说明

  service命令用于管理系统服务，比如启动(start)、停止(stop)、重启(restart)、重新加载配置(reload)、查看状态(status)等，该命令在Centos7中被systemctl取代

格式

  service [option] [command]

参数说明

• —status-all：显示所有服务状态

示例

1、查看当前服务状态

[root@localhost ~]# service --status-all
● iprdump.service - LSB: Start the ipr dump daemon
   Loaded: loaded (/etc/rc.d/init.d/iprdump; bad; vendor preset: disabled)
   Active: active (running) since Mon 2018-06-11 03:06:01 EDT; 5min ago
     Docs: man:systemd-sysv-generator(8)
  Process: 1293 ExecStart=/etc/rc.d/init.d/iprdump start (code=exited, status=0/SUCCESS)
 Main PID: 1391 (iprdump)
   CGroup: /system.slice/iprdump.service
           └─1391 /sbin/iprdump --daemon
...

2、管理系统服务

[root@localhost ~]# service mysqld stop
Shutting down MySQL.. SUCCESS! 
[root@localhost ~]# service mysqld start
Starting MySQL.. SUCCESS! 
[root@localhost ~]# service mysqld restart
Shutting down MySQL.. SUCCESS! 
Starting MySQL.^[[A SUCCESS! 
[root@localhost ~]# service mysqld status
 SUCCESS! MySQL running (2932)
[root@localhost ~]# service mysqld stop
Shutting down MySQL.. SUCCESS!

3、在工作中，推荐使用/etc/init.d/mysqld这种方式来管理系统服务，这种格式可以使用tab进行补全，当忘记了服务的名称，就可以使用tab键。

[root@localhost ~]# /etc/init.d/mysqld stop
Shutting down MySQL.. SUCCESS! 
[root@localhost ~]# /etc/init.d/mysqld start
Starting MySQL. SUCCESS! 
[root@localhost ~]# /etc/init.d/mysqld status
 SUCCESS! MySQL running (3265)
[root@localhost ~]# /etc/init.d/mysqld restart
Shutting down MySQL.. SUCCESS! 
Starting MySQL. SUCCESS!
