centos7 systemd加入mysqld.service

写一个mysql.service

vim mysql.service

[Unit]

Description=MySQL Server
Documentation=man:mysqld(5.7)

After=network.target
After=syslog.target
Before=shutdown.target # 关机前操作

[Install]
WantedBy=multi-user.target
Alias=mysql.service

[Service]
User=mysql
Group=mysql

Type=forking
PIDFile=/var/lib/mysql/Devops-mysql-master.pid

#Disable service start and stop timeout logic of systemd for mysqld service.
TimeoutSec=0

#Execute pre and post scripts as root
PermissionsStartOnly=true

#Needed to create system tables
ExecStartPre=/usr/bin/mysqld_pre_systemd

#Start|Stop main service
ExecStart=/etc/init.d/mysqld start
ExecStop=/etc/init.d/mysqld stop

#Sets open_files_limit
LimitNOFILE = 5000
Restart=on-failure
RestartPreventExitStatus=1
PrivateTmp=false

配置了mysql.service直接推送到/usr/lib/systemd/system目录中

#添加了mysql.service后，需要daemon-reload
systemctl daemon-reload

查看数据库状态

#直接查看启动
systemctl status mysqld
systemctl start mysqld
