Installation on Slackware 13

2011-08-03T11:55:00Z

Tnkflx: /* Contact */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working. If not, have a look at [http://linux-vserver.org/Installation_on_Linux_2.6 this] page.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages ("*.tgz" or "*.txz") to be installed are stored. This folder will be automatically created by these scripts.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the packages in the PKG_LIST list. If you use this scriptlet all the packages will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is a shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modifies ''/etc/rc.d/rc.6'' ''/etc/rc.d/rc.M'' and ''/etc/rc.d/rc.inet2''. It must be applied after the creation of the guest. In the patch I switched off all the mounts and executables that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.37/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.37/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

Installation on Slackware 13

2011-08-03T11:53:25Z

Tnkflx: /* Download the patch and the installer script */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working. If not, have a look at [http://linux-vserver.org/Installation_on_Linux_2.6 this] page.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages ("*.tgz" or "*.txz") to be installed are stored. This folder will be automatically created by these scripts.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the packages in the PKG_LIST list. If you use this scriptlet all the packages will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is a shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modifies ''/etc/rc.d/rc.6'' ''/etc/rc.d/rc.M'' and ''/etc/rc.d/rc.inet2''. It must be applied after the creation of the guest. In the patch I switched off all the mounts and executables that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.37/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.37/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

Installation on Slackware 13

2011-08-03T11:50:35Z

Tnkflx: /* Download the patch and the installer script */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working. If not, have a look at [http://linux-vserver.org/Installation_on_Linux_2.6 this] page.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored. This folder will be automatically created by these scripts.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modify ''rc.6'' ''rc.M'' and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then

exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.37/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.37/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

Installation on Slackware 13

2011-08-03T11:49:02Z

Tnkflx:

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working. If not, have a look at [http://linux-vserver.org/Installation_on_Linux_2.6 this] page.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder. This folder will be automatically created.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modify ''rc.6'' ''rc.M'' and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.37/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.37/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

Installation on Slackware 13

2011-08-03T11:33:02Z

Tnkflx: /* Download the patch and the installer script */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working. If not, have a look at [http://linux-vserver.org/Installation_on_Linux_2.6 this] page.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder. This folder will be automatically created.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modify ''rc.6'' ''rc.M'' and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.37/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.37/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Contact ==
Any comments/suggestions/questions to ''roberto dot puzzanghera at sagredo dot eu'', [http://notes.sagredo.eu]

== Patch used ==
<pre>
Patch for Slackware 13.37 guest on a Linux-Vserver host

Installation on Slackware 13

2011-08-03T11:29:22Z

Tnkflx:

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working. If not, have a look at [http://linux-vserver.org/Installation_on_Linux_2.6 this] page.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modify ''rc.6'' ''rc.M'' and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.37/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.37/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>
