<p>Verit: </p> <hr /> <div>=Install Patched vyum=<br /> <br /> == The Issue ==<br /> If you are getting the following error:-<br /> <br /> You are using a version of yum which is insecure and broken in chroot<br /> related operations; either apply the patches shipped in the 'contrib/'<br /> directory of util-vserver, or ask the author of yum to apply them<br /> (preferred).<br /> In the meantime, 'vyum' will continue with dirty hacks which might not<br /> work when the vserver is running and local DOS attacks are possible.<br /> Execution will continue in 5 seconds...<br /> <br /> == How to solve ==<br /> <br /> Find your Yum version<br /> yum --version<br /> <br /> Change directory<br /> cd /usr/src/*/SOURCES/<br /> <br /> Next find the correct patch at http://svn.linux-vserver.org/svn/util-vserver/trunk/contrib/ and download it (replace X.X.X with your yum version)<br /> wget http://svn.linux-vserver.org/svn/util-vserver/trunk/contrib/yum-X.X.X-chroot.patch<br /> <br /> Now lets create a directory to build all this<br /> cd /root<br /> mkdir yum-chroot<br /> cd yum-chroot<br /> <br /> Go to http://rpm.pbone.net/ and search for yum-X.X.X<br /> Pick the correct version eg 32 or 64bit, etc<br /> Then click the SOURCE file (important, don’t go to the RPM's)<br /> Select the right option from the list (eg. Centos or Redhat)<br /> Then pick a mirror (replace X.X.X with your yum version)<br /> wget ftp://ftp.nluug.nl/pub/os/Linux/distr/CentOS/5.0/os/SRPMS/yum-X.X.X-1.el5.centos.2.src.rpm<br /> rpm -i yum-X.X.X-1.el5.centos.2.src.rpm<br /> <br /> Now we will have 'yum.spc' file to modify, move it to our working directory<br /> cp /usr/src/*/SPECS/yum.spec .<br /> <br /> Edit the yum.spec file and find Patch lines as below (yours may be different):-<br /> Patch1: yum.conf.centos<br /> Patch2: yum-fix-install.patch<br /> And add another patch line after last Patch eg.<br /> Patch1: yum.conf.centos<br /> Patch2: yum-fix-install.patch<br /> Patch3: yum-X.X.X-chroot.patch (replace X with version)<br /> Then find:-<br /> %patch1 -p1<br /> %patch2 -p1<br /> And add another line with the same number you added above:-<br /> %patch1 -p1<br /> %patch2 -p1<br /> %patch3 -p1<br /> Save and exit<br /> <br /> <br /> Now the build<br /> rpmbuild -ba yum.spec<br /> <br /> Now update yum to our patched version<br /> rpm -U /usr/src/*/RPMS/noarch/yum-*<br /> <br /> vyum should now be patched, to test<br /> vyum &lt;vserver_name&gt; -- update</div>
