Here is the final step ( CentOS 5 ):

– Comment out basedir in /etc/my.cnf

#basedir=/var/lib

– Create new directory if not exists

mkdir /var/run/mysqld
chown mysql.mysql /var/run/mysqld

– Done

service mysql start

great post. Have been having the same problem, now sorted. Thanks.

@ David Grega. Yeah, the detailed instructions are there but it just fails to update to v5 from v4, does not matter what one does.

Note, /scripts/mysqlup (also called when you go to the Software section of the WHM interface and click Update Server Software) will only update you to the latest version of the branch of MySQL you are using. Therefore if you are using MySQL 4.1, by design, it will only update you to the latest MySQL 4.1 version. If you are using MySQL 5.0, then it will only update you to the latest 5.0 version.

Detailed instructions for upgrading from MySQL 4.1 to 5.0 are right in the WHM interface in the setting that controls the MySQL version (in WHM -> Server Configuration -> Tweak Settings -> MySQL).

Note that after such an upgrade, you should recompile Apache and PHP via EasyApache to ensure PHP scripts interact properly with the new MySQL version rather than generate errors.

Additionally, MySQL 5.0 is not readily downgradable to 4.1 so be sure to make a backup BEFORE upgrading.
