Mysql cannot execute binary file upcp fails error 25

[sajugovind]

If you see this in the mysql log when starting mysql, and can not run upcp;

Code: [Select]

/usr/sbin/mysqld: /usr/sbin/mysqld: cannot execute binary file
140513 00:16:10 mysqld_safe mysqld from pid file /var/lib/mysql/<hostname>.pid ended

The RPM's likely need to be rebuilt:

Code: [Select]

/bin/rm -rf /var/lib/rpm/__db.*
rpm --rebuilddb
/scripts/check_cpanel_rpms --fix
Then run

Code: [Select]

/scripts/upcp --force
The problem is that this file:

/var/cpanel/sysinfo.config

This line:

rpm_dist_ver=unknown

Needs to match the major version of the OS on the machine, for Centos 6.5:

rpm_dist_ver=6

Centos 5.x:

rpm_dist_ver=5
