Installs and configures PostgreSQL server on RHEL/CentOS or Debian/Ubuntu servers.
No special requirements; note that this role requires root access, so either run it in a playbook with a global become: yes, or invoke the role in your playbook like:
- hosts: database
roles:
- role: geerlingguy.postgresql
become: yes
Available variables are listed below, along with default values (see defaults/main.yml):
postgresql_enablerepo: ""
(RHEL/CentOS only) You can set a repo to use for the PostgreSQL installation by passing it in here.
postgresql_restarted_state: "restarted"
Set the state of the service when configuration changes are made. Recommended values are restarted or reloaded.
postgresql_python_library: python-psycopg2
Library used by Ansible to communicate with PostgreSQL. If you are using Python 3 (e.g. set via ansible_python_interpreter), you should change this to python3-psycopg2.
postgresql_user: postgres
postgresql_group: postgres
The user and group under which PostgreSQL will run.
postgresql_unix_socket_directories:
- /var/run/postgresql
The directories (usually one, but can be multiple) where PostgreSQL's socket will be created.
postgresql_service_state: started
postgresql_service_enabled: true
Control the state of the postgresql service and whether it should start at boot time.
postgresql_global_config_options:
- option: unix_socket_directories
value: '{{ postgresql_unix_socket_directories | join(",") }}'
Global configuration options that will be set in postgresql.conf. Note that for RHEL/CentOS 6 (or very old versions of PostgreSQL), you need to at least override this variable and set the option to unix_socket_directory.
postgresql_hba_entries:
- { type: local, database: all, user: postgres, auth_method: peer }
- { type: local, database: all, user: all, auth_method: peer }
- { type: host, database: all, user: all, address: '127.0.0.1/32', auth_method: md5 }
- { type: host, database: all, user: all, address: '::1/128', auth_method: md5 }
Configure host based authentication entries to be set in the pg_hba.conf. Options for entries include:
type(required)database(required)user(required)address(one of this or the following two are required)ip_addressip_maskauth_method(required)auth_options(optional)
If overriding, make sure you copy all of the existing entries from defaults/main.yml if you need to preserve existing entries.
