Hello CentOS users,

for a Wordpress website I have installed mysql-server-5.1.69-1.el6_4.x86_64 and run /usr/bin/mysql_secure_installation on a CentOS 6.4 machine with mucho RAM (32 GB) and I wonder, what would be the best place for the mysqld parameters descibed at http://dev.mysql.com/doc/refman/5.1/en/server-parameters.html

mysqld_safe --key_buffer_size=64M --table_open_cache=256 \ --sort_buffer_size=4M --read_buffer_size=1M &

Should I just edit the file /etc/init.d/mysqld or is there a better place in CentOS for that (under sysconfig?)

Don't touch the init script. It would get overridden by a future package update.

/etc/my.cnf is the configuration file where you add all the desired tuning options. It will not be touched by an update.

For your help the mysql-server package ships with example configurations for different setups:

/usr/share/mysql/*.cnf

I had my.cnf replaced when it was a symlink. It was a linked to shared storage (drbd mount). It may have been replaced because the shared storage wasn't mounted so it was a "broken" link. chattr +i would probably have kept it from happening. It's an edge case, but it's worth keeping in mind if you're doing anything cute.
