Should pid File path
what ? The app you queried doesn't have this one --pid-file= parameter , Then it means that the application is not specified pid, The random distribution of the system is used , What should I do? ? Create it yourself , Just check the data and create one
[root@admin conf]# ps -ef|grep mysql mysql 2937 1 0 08:53 ? 00:00:00 /bin/sh /
usr/bin/mysqld_safe --basedir=/usr mysql 3167 2937 0 08:53 ? 00:00:15 /usr/sbin/
mysqld-- basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/
plugin--log-error=/var/log/mysqld.log --pid-file=/var/run/mysqld/mysqld.pid --
