一、chkconfig 介绍
二、service 介绍
1、常见 service 命令
[root@localhost ~]# service supervisord stop [root@localhost ~]# service supervisord start [root@localhost ~]# service supervisord status [root@localhost ~]# service --status-all # 查看Linux所有服务的运行状态
三、systemctl 介绍
1、常见 systemctl 命令
[root@localhost ~]# systemctl stop supervisord [root@localhost ~]# systemctl start supervisord [root@localhost ~]# systemctl status supervisord [root@localhost ~]# systemctl restart supervisord [root@localhost ~]# systemctl is-active supervisord # 查看服务是否运行 [root@localhost ~]# systemctl enable supervisord # 设置服务允许开机启动 [root@localhost ~]# systemctl disable supervisord # 设置服务禁止开机启动 [root@localhost ~]# systemctl is-enabled supervisord # 查看服务是否设置为开机启动，得到的值可以是enable、disable或static，这里的 static 它是指对应的 Unit 文件中没有定义[Install]区域，因此无法配置为开机启动服务。 [root@localhost ~]# systemctl daemon-reload # 添加.service文件后，或者变更.service文件设置后，需要执行一下这个 [root@localhost ~]# systemctl list-unit-files # 查看开机启动项 [root@localhost ~]# systemctl list-unit-files | grep 程序名称 # 查看某些服务开机启动状态 [root@localhost ~]# systemctl list-unit-files | grep enable # 查看哪些为开机启动服务 [root@localhost ~]# systemctl list-units --type=service # 查看所有已启动的服务 [root@localhost ~]# systemctl --failed # 查看启动失败的服务列表 [root@localhost ~]# systemctl mask supervisord # 注销supervisord服务 [root@localhost ~]# systemctl unmask supervisord # 取消注销supervisord服务 [root@localhost ~]# systemctl get-default # 获得当前的运行级别 [root@localhost ~]# systemctl set-default multi-user.target # 设置默认的运行级别为mulit-user，即开机不开启图形 [root@localhost ~]# systemctl set-default graphical.target # 设置默认的运行级别为mulit-user，即开机启动图形 [root@localhost ~]# systemctl isolate multi-user.target # 在不重启的情况下，切换到运行级别mulit-user下 [root@localhost ~]# systemctl isolate graphical.target # 在不重启的情况下，切换到图形界面下
