Sebastian Schwarz 64e337194c Make MySQL root username configurable While this doesn't seem to make sense on first glance it is useful for systems which were screwed with Parallels Plesk, which renames the MySQL root user to "admin". This change allowes this role to be used while the server is transitioning from Plesk to Ansible.		2014-08-07 14:26:05 +02:00

Ansible Role: MySQL

Installs MySQL server on RHEL/CentOS or Debian/Ubuntu servers.

Requirements

None.

Role Variables

Available variables are listed below, along with default values (see vars/main.yml):

mysql_user_home: /root

The home directory inside which Python MySQL settings will be stored, which Ansible will use when connecting to MySQL. This should be the home directory of the user which runs this Ansible role.

mysql_root_password: root

The MySQL root user account password.

mysql_databases: []

The MySQL databases to create. A database has the values name, encoding (defaults to utf8) and collation (defaults to utf8_general_ci). The formats of these are the same as in the mysql_db module.

mysql_users: []

The MySQL users and their privileges. A user has the values name, host (defaults to localhost), password and priv (defaults to *.*:USAGE). The formats of these are the same as in the mysql_user module.

mysql_packages:
  - mysql
  - mysql-server
  - MySQL-python

(OS-specific, RedHat/CentOS defaults listed here) Packages to be installed. In some situations, you may need to add additional packages, like mysql-devel.

mysql_enablerepo: ""

(RedHat/CentOS only) If you have enabled any additional repositories (might I suggest geerlingguy.repo-epel or geerlingguy.repo-remi), those repositories can be listed under this variable (e.g. remi,epel). This can be handy, as an example, if you want to install later versions of MySQL.

mysql_port: "3306"
mysql_datadir: /var/lib/mysql
mysql_socket: /var/lib/mysql/mysql.sock

Default MySQL connection configuration.

mysql_key_buffer_size: "256M"
mysql_max_allowed_packet: "1M"
mysql_table_open_cache: "256"
[...]

The rest of the settings in defaults/main.yml control MySQL's memory usage. The default values are tuned for a server where MySQL can consume ~512 MB RAM, so you should consider adjusting them to suit your particular server better.

Dependencies

None.

Example Playbook

- hosts: db-servers
  vars_files:
    - vars/main.yml
  roles:
    - { role: geerlingguy.mysql }

Inside vars/main.yml:

mysql_root_password: super-secure-password
mysql_databases:
  - name: example_db
    encoding: latin1
    collation: latin1_general_ci
mysql_users:
  - name: example_user
    host: "%"
    password: similarly-secure-password
    priv: "example_db.*:ALL"
