　　centos 7 开始使用systemctl 管理服务
　　

　　服务脚本目录 /etc/systemd/system/mysql.service
　　脚本如下：
　　

　　

　　

　　#
　　# Simple MySQL systemd service file
　　#
　　# systemd supports lots of fancy features, look here (and linked docs) for a full list:
　　#  http://www.freedesktop.org/software/systemd/man/systemd.exec.html
　　#
　　# Note: this file ( /usr/lib/systemd/system/mysql.service )
　　# will be overwritten on package upgrade, please copy the file to
　　#
　　#  /etc/systemd/system/mysql.service
　　#
　　# to make needed changes.
　　#
　　# systemd-delta can be used to check differences between the two mysql.service files.

　　mysqld_pre_systemd (RPM platforms), mysql-system-start (Debian platforms): Support script for the unit file. This script assists in creating the error log file only if the log location matches a pattern (/var/log/mysql*.log for RPM platforms, /var/log/mysql/*.log for Debian platforms). In other cases, the error log directory must be writable or the error log must be present and writable for the user running the mysqld process.
　　

　　

　　如果 mysql error log 设置在 /var/log 下

　　

　　以下是percona mysql 设置
　　

　　

[root@c52cbe15cfa3 system]# cat mysqld.service

　　#
　　# Systemd service file for Percona Server
　　#
　　# # This service file is to start PS just with mysqld_safe
　　#
