Percona won't read /etc/my.cnf

I know that it’s trying to read it. From mysqld --help --verbose | head -n 30:

Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf

And permissions:

-rw-r–r--. 1 root root 425 Jul 9 16:28 /etc/my.cnf

Any suggestions? Thanks.

Disabling selinux fixed it.

Permissions look fine. I’m guessing that you are thinking that the config file is not being read because MySQL (Percona) is doing something that you are not expecting? If so, please post up the symptoms / errors and we can try and help find the cause.
