Percona Server 5.7 ignores --pid-file in my.cnf

[Miguel Angel Nieto]

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
log-error=/var/log/mysqld.log
pid_file=/tmp/mysqld.pid

[mysqld_safe]
pid_file=/tmp/mysqld.pid

Still, mysqld uses:

/usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid

To make it work as expected I need to modify /etc/systemd/system/mysql.service

First comment the following line:

#PIDFile=/var/run/mysqld/mysqld.pid

then change this one:

ExecStart=/usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid $MYSQLD_OPTS

to this:

ExecStart=/usr/sbin/mysqld --daemonize
