# ansible-role-mariadb
|
||||
Ansible Role: MariaDB
|
||||
# Ansible role: MariaDB
|
||||
|
||||
[](https://travis-ci.org/fauust/ansible-role-mariadb)
|
||||
|
||||
Install and configure MariaDB server on Debian/Ubuntu.
|
||||
|
||||
Optionally, this role also permits to:
|
||||
|
||||
- deploy a master/slave cluster;
|
||||
- setup backups and rotation of the dumps.
|
||||
|
||||
## Requirements
|
||||
|
||||
The role use
|
||||
[`mysql_user`](https://docs.ansible.com/ansible/latest/modules/mysql_user_module.html)
|
||||
and
|
||||
[`mysql_db`](https://docs.ansible.com/ansible/latest/modules/mysql_db_module.html)
|
||||
ansible modules that depends on [PyMySQL](https://github.com/PyMySQL/PyMySQL) so
|
||||
the following Python 2.7 or Python 3.X versions are needed.
|
||||
|
||||
For older Python versions, you may use
|
||||
[MySQLdb](http://mysql-python.sourceforge.net/MySQLdb.html) but then the role
|
||||
may not be idempotent (not tested).
|
||||
|
||||
## Fact gathering (performance)
|
||||
|
||||
Unless you want to use the MariaDB official repository (and then need
|
||||
`ansible_distribution_version`, see [`tasks/setup.yml`](./tasks/setup.yml)) this
|
||||
role does not require fact gathering.
|
||||
|
||||
## Role variables
|
||||
|
||||
Available variables are listed below, along with default values (see
|
||||
[`defaults/main.yml`](./defaults/main.yml)):
|
||||
|
||||
### MariaDB version
|
||||
|
||||
```yaml
|
||||
mariadb_use_official_repo: false
|
||||
mariadb_use_official_repo_url: "http://ftp.igh.cnrs.fr/pub/mariadb/repo"
|
||||
mariadb_use_official_repo_version: "10.4"
|
||||
```
|
||||
|
||||
You may deploy the MariaDB Server version that comes with your distribution (Debian/Ubuntu) or
|
||||
deploy the version packaged by the MariaDB Foundation.
|
||||
You will find the repositories URL here:
|
||||
<https://downloads.mariadb.org/mariadb/repositories/>
|
||||
|
||||
By default we deploy the MariaDB Server version that comes with the distribution.
|
||||
|
||||
### MariaDB service activation and restart
|
||||
|
||||
```yaml
|
||||
mariadb_enabled_on_startup: true
|
||||
mariadb_can_restart: true
|
||||
```
|
||||
|
||||
**Warning:** you may consider setting `mariadb_can_restart` to `false` on
|
||||
production systems to prevent ansible runs to restart the MariaDB server.
|
||||
|
||||
### General configuration
|
||||
|
||||
To populate the MariaDB Server configuration file, we use almost only raw
|
||||
variables. This permits more flexibility and a very simple
|
||||
[`templates/my.cnf.j2`](./templates/my.cnf.j2) file.
|
||||
|
||||
By default, some common and standard options are deployed.
|
||||
|
||||
#### Basic settings
|
||||
|
||||
The following variables are also needed by playbooks so we can not use raw
|
||||
variables.
|
||||
|
||||
```yaml
|
||||
mariadb_config_file: /etc/mysql/my.cnf
|
||||
mariadb_datadir: "/var/lib/mysql"
|
||||
mariadb_port: "3306"
|
||||
mariadb_bind_address: "127.0.0.1"
|
||||
mariadb_unix_socket: "/run/mysqld/mysqld.sock"
|
||||
```
|
||||
|
||||
```yaml
|
||||
mariadb_basic_settings_raw: |
|
||||
user = mysql
|
||||
pid-file = /run/mysqld/mysqld.pid
|
||||
socket = {{ mariadb_unix_socket }}
|
||||
basedir = /usr
|
||||
datadir = {{ mariadb_datadir }}
|
||||
tmpdir = /tmp
|
||||
lc-messages-dir = /usr/share/mysql
|
||||
lc_messages = en_US
|
||||
skip-external-locking
|
||||
port = {{ mariadb_port }}
|
||||
bind-address = {{ mariadb_bind_address }}
|
||||
```
|
||||
|
||||
#### Fine tuning
|
||||
|
||||
```yaml
|
||||
mariadb_fine_tuning_raw: |
|
||||
max_connections = 100
|
||||
connect_timeout = 5
|
||||
wait_timeout = 600
|
||||
max_allowed_packet = 16M
|
||||
thread_cache_size = 128
|
||||
sort_buffer_size = 4M
|
||||
bulk_insert_buffer_size = 16M
|
||||
tmp_table_size = 32M
|
||||
max_heap_table_size = 32M
|
||||
```
|
||||
|
||||
#### Query cache
|
||||
|
||||
```yaml
|
||||
mariadb_query_cache_raw: |
|
||||
query_cache_size = 16M
|
||||
```
|
||||
|
||||
#### Logging
|
||||
|
||||
```yaml
|
||||
mariadb_logging_raw: |
|
||||
log_error = /var/log/mysql/error.log
|
||||
```
|
||||
|
||||
#### Character sets
|
||||
|
||||
```yaml
|
||||
mariadb_character_sets_raw: |
|
||||
character-set-server = utf8mb4
|
||||
collation-server = utf8mb4_general_ci
|
||||
```
|
||||
|
||||
#### InnoDB
|
||||
|
||||
```yaml
|
||||
mariadb_innodb_raw: |
|
||||
# InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.
|
||||
# Read the manual for more InnoDB related options. There are many!
|
||||
```
|
||||
|
||||
#### Mariadbdump
|
||||
|
||||
```yaml
|
||||
mariadb_mysqldump_raw: |
|
||||
quick
|
||||
quote-names
|
||||
max_allowed_packet = 16M
|
||||
```
|
||||
|
||||
### Databases management
|
||||
|
||||
```yaml
|
||||
# Databases.
|
||||
mariadb_databases: []
|
||||
# - name: db1
|
||||
# collation: utf8_general_ci
|
||||
# encoding: utf8
|
||||
# replicate: true|false
|
||||
```
|
||||
|
||||
See: <https://docs.ansible.com/ansible/latest/modules/mysql_db_module.html>
|
||||
|
||||
### Users management
|
||||
|
||||
```yaml
|
||||
# Users.
|
||||
mariadb_users: []
|
||||
# - name: user
|
||||
# host: 100.64.200.10
|
||||
# password: password
|
||||
# priv: "*.*:USAGE/db1.*:ALL"
|
||||
# state: present|absent
|
||||
```
|
||||
|
||||
See: <https://docs.ansible.com/ansible/latest/modules/mysql_user_module.html>
|
||||
|
||||
### Replication (optional)
|
||||
|
||||
Replication is only enabled if `mariadb_replication_role` has a value (`master` or
|
||||
`slave`).
|
||||
|
||||
The replication setup on the slave use the GTID autopositionning
|
||||
`master_use_gtid=slave_pos`. See:
|
||||
<https://mariadb.com/kb/en/library/change-master-to/#master_use_gtid>
|
||||
|
||||
For the moment, we use an `SQL` command but in ansible 2.10, we should be able
|
||||
to use the
|
||||
[`mysql_replication`](https://docs.ansible.com/ansible/latest/modules/mysql_replication_module.html)
|
||||
module (see
|
||||
[`tasks/replication_slave.yml`](./tasks/replication_slave.yml#L09-L33) and
|
||||
<https://github.com/ansible/ansible/pull/62648>).
|
||||
|
||||
```yaml
|
||||
mariadb_replication_role: "" # master|slave
|
||||
mariadb_replication_master_ip: ""
|
||||
mariadb_server_id: "1"
|
||||
mariadb_max_binlog_size: "100M"
|
||||
mariadb_binlog_format: "MIXED"
|
||||
mariadb_expire_logs_days: "10"
|
||||
|
||||
# Same keys as `mariadb_users` above.
|
||||
# priv is set to "*.*:REPLICATION SLAVE" by default
|
||||
mariadb_replication_user: []
|
||||
```
|
||||
|
||||
### Backups (optional)
|
||||
|
||||
```yaml
|
||||
# db dumps backup
|
||||
mariadb_backup_db: false
|
||||
mariadb_backup_db_cron_min: "50"
|
||||
mariadb_backup_db_cron_hour: "00"
|
||||
mariadb_backup_db_dir: "/mnt/backup"
|
||||
mariadb_backup_db_rotation: "15"
|
||||
|
||||
# name of the database to dump
|
||||
# (mandatory if mariadb_backup_db is set to true)
|
||||
mariadb_backup_db_name: []
|
||||
# - db1
|
||||
# - db2
|
||||
```
|
||||
|
||||
Database dump is done serially and compression (`gzip`) is done at the end to
|
||||
avoid too long locks.
|
||||
|
||||
## Example Playbook
|
||||
|
||||
```yaml
|
||||
- hosts: database
|
||||
roles:
|
||||
- fauust.mariadb
|
||||
```
