4. 配置启动服务

   [root@bluse /]# cat /usr/lib/systemd/system/redis.service
   [Unit]
   Description=Redis
   After=network.target
   
   [Service]
   Type=forking
   PIDFile=/var/run/redis_6379.pid
   ExecStart=/data1/srv/redis/bin/redis-server /data1/srv/redis/bin/redis.conf
   ExecReload=/bin/kill -s HUP $MAINPID
   ExecStop=/bin/kill -s QUIT $MAINPID
   PrivateTmp=true
   
   [Install]
   WantedBy=multi-user.target

   • [Install]

     • WantedBy=multi-user.target

   • [Unit] 表示这是基础信息

     • Description 是描述
     • After 是在那个服务后面启动，一般是网络服务启动后启动

   • [Service] 表示这里是服务信息 ExecStart 是启动服务的命令

     • ExecStop 是停止服务的指令

   • [Install] 表示这是是安装相关信息 WantedBy 是以哪种方式启动：

     • multi-user.target表明当系统以多用户方式（默认的运行级别）启动时，这个服务需要被自动运行。

systemctl daemon-reload
systemctl enable redis && systemctl start redis
