systemd - Manage services.

New in version 2.2.

Synopsis

  • Controls systemd services on remote hosts.

Requirements (on host that executes module)

  • A system managed by systemd

Options

parameter required default choices comments
daemon_reload
no
  • yes
  • no
run daemon-reload before doing any other operations, to make sure systemd has read any changes.

aliases: daemon-reload
enabled
no
  • yes
  • no
Whether the service should start on boot. At least one of state and enabled are required.
masked
no
  • yes
  • no
Whether the unit should be masked or not, a masked unit is impossible to start.
name
no
Name of the service. When using in a chroot environment you always need to specify the full name i.e. (crond.service).

aliases: unit, service
no_block
(added in 2.3)
no
  • yes
  • no
Do not synchronously wait for the requested operation to finish. Enqueued job will continue without Ansible blocking on its completion.
state
no
  • started
  • stopped
  • restarted
  • reloaded
started/stopped are idempotent actions that will not run commands unless necessary. restarted will always bounce the service. reloaded will always reload.
user
no
  • yes
  • no
run systemctl talking to the service manager of the calling user, rather than the service manager of the system.

Examples

- name: Make sure a service is running
  systemd: state=started name=httpd

- name: stop service cron on debian, if running
  systemd: name=cron state=stopped

- name: restart service cron on centos, in all cases, also issue daemon-reload to pick up config changes
  systemd:
    state: restarted
    daemon_reload: yes
    name: crond

- name: reload service httpd, in all cases
  systemd:
    name: httpd
    state: reloaded

- name: enable service httpd and ensure it is not masked
  systemd:
    name: httpd
    enabled: yes
    masked: no

- name: enable a timer for dnf-automatic
  systemd:
    name: dnf-automatic.timer
    state: started
    enabled: True

- name: just force systemd to reread configs (2.4 and above)
  systemd: daemon_reload=yes

Notes

Note

  • Since 2.4, one of the following options is required ‘state’, ‘enabled’, ‘masked’, ‘daemon_reload’, and all except ‘daemon_reload’ also require ‘name’.
  • Before 2.4 you always required ‘name’.
