13.3. 列出系统服务



  • 要列出所有当前载入的服务单元,请输入:

    $ systemctl list-units --type service
    UNIT                     LOAD   ACTIVE SUB     DESCRIPTION
    abrt-ccpp.service        loaded active exited  Install ABRT coredump hook
    abrt-oops.service        loaded active running ABRT kernel log watcher
    abrtd.service            loaded active running ABRT Automated Bug Reporting Tool
    systemd-vconsole-setup.service loaded active exited  Setup Virtual Console
    tog-pegasus.service            loaded active running OpenPegasus CIM Server
    LOAD   = Reflects whether the unit definition was properly loaded.
    ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
    SUB    = The low-level unit activation state, values depend on unit type.
    46 loaded units listed. Pass --all to see loaded but inactive units, too.
    To show all installed unit files use 'systemctl list-unit-files'

    默认情况下,systemctl list-units 命令只显示活跃的单位。对于每个服务单元文件,命令会显示:

    • UNIT :其全名
    • LOAD :是否载入了单元文件的信息
    • ACTIVE\ SUB :其高级别和低级单元文件激活状态
    • DESCRIPTION: 一个较短的描述信息
  • 要列出所有载入的单元,而不考虑其状态,使用 --all-a 命令行选项输入以下命令:

    $ systemctl list-units --type service --all
  • 要列出所有可用服务单元的状态(启用/禁用),请输入:

    $ systemctl list-unit-files --type service
    UNIT FILE                               STATE
    abrt-ccpp.service                       enabled
    abrt-oops.service                       enabled
    abrtd.service                           enabled
    wpa_supplicant.service                  disabled
    ypbind.service                          disabled
    208 unit files listed.


    • UNIT FILE :其全名
    • STATE :是否启用或禁用服务单元
