[ENSIM] CentOS 5 updates introduce new keyutils-libs RPM, breaking multiple services
After applying some recent updates to CentOS 5 Ensim Pro 10 servers, we started to receive error message emails from the MailQueueCleaner (MailQueueCleaner failure reports), which said the following:
domain.com: sendmail error, stdout: [], stderr: ['/usr/sbin/sendmail: error while loading shared libraries: libkeyutils.so.1: cannot open shared object file: No such file or directory\n'], exit code: 127
It turns out that recent updates to the krb5-libs package now require the installation of keyutils-libs as a dependency. Unfortunately, Ensim at this time is not set up to roll this package out to the virtual filesystems of individual sites, so various services (including virthostmail) fail, mentioning the libkeyutils.so file above.
To fix this problem, you will need to add a custom package script in the
/etc/virtualhosting/filelists/ directory. I added a file called
sendmail.custom.sh, which had the following contents:
#!/bin/bash
read
while [ $? == 0 ]; do
echo $REPLY
read
done
echo "S,rpm:keyutils-libs"
Create this file on your server, then run the system through maintenance to roll out the fix to all the virtual sites:
set_pre_maintenance && set_maintenance && set_post_maintenance
service epld start
While I fixed this by creating a sendmail.custom.sh file, I have seen
that others have used apache.custom.sh. Either way seems to work and the naming of these
files only seems to be used as a way to remember what service an RPM is required for. As this RPM
affects several services, your custom.sh script could potentially use any name...
