5）查看 SysV 服务启动状态

[root@lee ~]# chkconfig --list注意：该输出结果只显示 SysV 服务，并不包含原生 systemd 服务。SysV 配置数据可能被原生 systemd 配置覆盖。       如果您想列出 systemd 服务,请执行 'systemctl list-unit-files'。      欲查看对特定 target 启用的服务请执行      'systemctl list-dependencies [target]'。netconsole      0:关 1:关 2:关 3:关 4:关 5:关 6:关network         0:关 1:关 2:开 3:开 4:开 5:开 6:关rhnsd           0:关 1:关 2:开 3:开 4:开 5:开 6:关
