ansible.builtin.systemd – Manage systemd units

Note

This module is part of ansible-core and included in all Ansible installations. In most cases, you can use the short module name systemd even without specifying the collections: keyword. However, we recommend you use the FQCN for easy linking to the module documentation and to avoid conflicting with other collections that may have the same module name.

New in version 2.2: of ansible.builtin

Synopsis

Controls systemd units (services, timers, and so on) on remote hosts.

Requirements

The below requirements are needed on the host that executes this module.

A system managed by systemd.

Parameters

Parameter	Choices/Defaults	Comments
daemon_reexec boolean added in 2.8 of ansible.builtin	Choices: no ← yes	Run daemon_reexec command before doing any other operations, the systemd manager will serialize the manager state. aliases: daemon-reexec
daemon_reload boolean	Choices: no ← yes	Run daemon-reload before doing any other operations, to make sure systemd has read any changes. When set to `true`, runs daemon-reload even if the module does not start or stop anything. aliases: daemon-reload
enabled boolean	Choices: no yes	Whether the unit should start on boot. At least one of state and enabled are required.
force boolean added in 2.6 of ansible.builtin	Choices: no yes	Whether to override existing symlinks.
masked boolean	Choices: no yes	Whether the unit should be masked or not, a masked unit is impossible to start.
name string		Name of the unit. This parameter takes the name of exactly one unit to work with. When no extension is given, it is implied to a `.service` as systemd. When using in a chroot environment you always need to specify the name of the unit with the extension. For example, `crond.service`. aliases: service, unit
no_block boolean added in 2.3 of ansible.builtin	Choices: no ← yes	Do not synchronously wait for the requested operation to finish. Enqueued job will continue without Ansible blocking on its completion.
scope string added in 2.7 of ansible.builtin	Choices: system ← user global	Run systemctl within a given service manager scope, either as the default system scope `system`, the current user's scope `user`, or the scope of all users `global`. For systemd to work with 'user', the executing user must have its own instance of dbus started and accessible (systemd requirement). The user dbus process is normally started during normal login, but not during the run of Ansible tasks. Otherwise you will probably get a 'Failed to connect to bus: no such file or directory' error. The user must have access, normally given via setting the ``XDG_RUNTIME_DIR`` variable, see example below.
state string	Choices: reloaded restarted started stopped	`started`/`stopped` are idempotent actions that will not run commands unless necessary. `restarted` will always bounce the unit. `reloaded` will always reload.

Notes

Note

Since 2.4, one of the following options is required state, enabled, masked, daemon_reload, (daemon_reexec since 2.8), and all except daemon_reload and (daemon_reexec since 2.8) also require name.
Before 2.4 you always required name.
Globs are not supported in name, i.e postgres*.service.
Supports check_mode.

Examples

- name: Make sure a service unit is running
  ansible.builtin.systemd:
    state: started
    name: httpd

- name: Stop service cron on debian, if running
  ansible.builtin.systemd:
    name: cron
    state: stopped

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

- name: Reload service httpd, in all cases
  ansible.builtin.systemd:
    name: httpd.service
    state: reloaded

- name: Enable service httpd and ensure it is not masked
  ansible.builtin.systemd:
    name: httpd
    enabled: yes
    masked: no

- name: Enable a timer unit for dnf-automatic
  ansible.builtin.systemd:
    name: dnf-automatic.timer
    state: started
    enabled: yes

- name: Just force systemd to reread configs (2.4 and above)
  ansible.builtin.systemd:
    daemon_reload: yes

- name: Just force systemd to re-execute itself (2.8 and above)
  ansible.builtin.systemd:
    daemon_reexec: yes

- name: Run a user service when XDG_RUNTIME_DIR is not set on remote login
  ansible.builtin.systemd:
    name: myservice
    state: started
    scope: user
  environment:
    XDG_RUNTIME_DIR: "/run/user/{{ myuid }}"
