YUM Error CentOS Template [message #152]

I just installed all the latest RPM's and used the down loadable CentOS template from the OVZ website. I installed YUM into the newly created VPS via vzyum. When I try and use YUM from inside the VPS I get the following error:

# yum install nano

Any ideas how to solve this?

First, it's preferrable to use vzyum for installation of packages inside the VPS, just because that way there will be a common yum cache to be used by all VPSs based on a given OS template. Well, if you plan to have just one CentOS VPS, you can use yum from inside VPS as well.

So the questions are:
1. What your host system rpm and yum versions are? ('rpm -q rpm yum')
2. Does rpm -q work inside your VPS? What VPS' rpm and yum versions are? ('rpm -q rpm yum' inside VPS).
3. Try 'yum makecache' inside VPS if your yum version supports it

Ok, you brought up some important questions which I should have included in my original post. I did find a fix though Surprised

I used the following once and it solved my YUM problems then and thereafter:

PYTHONPATH=/usr/lib/python2.3/site-packages yum update

I'm guessing if I installed Python-Devel It might have cleared it up too. As always, thanks for assisting, It is much appreciated.

**EDIT**

I should explain that I used "vzpkgcache centos-4" to make a centos tar.gz for the /vz/templates/cache I tryed the above on a newly built VPS (102) with the new tar.gz file and it corrected the error. I tried the above on the original VPS (101) and it DID NOT correct the yum error even after installing python-devel.

So VPS 102 has a working YUM. As a side note "DF" yields no output on this CentOS install.

VPS 101 Does not have a working YUM but "DF" works as it should

As for 'df' problem, do you have /etc/mtab? Normally, it should be present and be a symlink to /proc/mounts

After creating a CentOS-4 VPS by following the steps outlined in the PDF userguide, mtab was a regular file with this content:

none /dev/pts devpts rw 0 0

We don't get df output with that, so removing that file and creating the symlink fixes things up.

rm -f /etc/mtab
ln -s /proc/mounts /etc/mtab

Once the symlink is created, df from inside the VPS correctly displays the amount of disk space free.

Example:

[root@vps ~]# df -h
Filesystem Size Used Avail Use% Mounted on
simfs 1.0G 413M 612M 41% /

This is a bug in centos-4 template that claimed to be fixed in 1.0-5 version of template metadata, but not actually fixed.

I just put the issue to bugzilla as bug #45. For now, to fix the bug please add the following lines to the end of /vz/template/centos/4/config/install-post file:

# Link /etc/mtab to /proc/mounts
rm -f $VE_ROOT/etc/mtab
ln -s /proc/mounts $VE_ROOT/etc/mtab

After that, you have to recreate template cache from scratch:

vzpkgcache -f centos-4
