  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] 示意这是根底信息

      • Description 是形容
      • After 是在那个服务前面启动,个别是网络服务启动后启动
    • [Service] 示意这里是服务信息 ExecStart 是启动服务的命令

      • ExecStop 是进行服务的指令
    • [Install] 示意这是是装置相干信息 WantedBy 是以哪种形式启动:

      • multi-user.target 表明当零碎以多用户形式(默认的运行级别)启动时,这个服务须要被主动运行。
systemctl daemon-reload
systemctl enable redis && systemctl start redis
