centos7 systemd加入mysqld.service

说明: 前面的数据库文章中提到数据库初始化主主
所以这里就直接接着上文写了

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
