• 配置文件 创建并修改配置文件vi /usr/lib/systemd/system/mysql.service,编辑内容如下：

[Unit]
Description=MySQL Server
Documentation=man:mysqld(8)
Documentation=http://dev.mysql.com/doc/refman/en/using-systemd.html
After=network.target
After=syslog.target

[Install]
WantedBy=multi-user.target

[Service]
User=mysql
Group=mysql
ExecStart=/usr/local/mysql/bin/mysqld
LimitNOFILE = 5000
#Restart=on-failure
#RestartPreventExitStatus=1
#PrivateTmp=false

• 测试是否可以正常启动 systemctl start mysql

[root@localhost ~]# ps -ef | grep mysql
mysql      1378      1  0 11:18 ?        00:00:01 /usr/local/mysql/bin/mysqld
root       3613   2017  0 11:21 pts/0    00:00:00 grep --color=auto mysql

查看是否有对应的进程

• 设置开机启动 systemctl enable mysql
