Ansible Role: PostgreSQL

Installs and configures PostgreSQL server on RHEL/CentOS or Debian/Ubuntu servers.

Requirements

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

Role Variables

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_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_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_locales:
  - 'en_US.UTF-8'

(Debian/Ubuntu only) Used to generate the locales used by PostgreSQL databases.

postgresql_databases:
  - name: exampledb # required; the rest are optional
    lc_collate: # defaults to 'en_US.UTF-8'
    lc_ctype: # defaults to 'en_US.UTF-8'
    encoding: # defaults to 'UTF-8'
    template: # defaults to 'template0'
    login_host: # defaults to 'localhost'
    login_password: # defaults to not set
    login_user: # defaults to 'postgresql_user'
    login_unix_socket: # defaults to 1st of postgresql_unix_socket_directories
    port: # defaults to not set
    state: # defaults to 'present'

A list of databases to ensure exist on the server. Only the name is required; all other properties are optional.

postgresql_users:
  - name: jdoe #required; the rest are optional
    password: # defaults to not set
    priv: # defaults to not set
    role_attr_flags: # defaults to not set
    db: # defaults to not set
    login_host: # defaults to 'localhost'
    login_password: # defaults to not set
    login_user: # defaults to '{{ postgresql_user }}'
    login_unix_socket: # defaults to 1st of postgresql_unix_socket_directories
    port: # defaults to not set
    state: # defaults to 'present'

postgresql_config_path: [OS-specific]
postgresql_daemon: [OS-specific]
postgresql_packages: [OS-specific]
