  • mysql (command line binary)
  • mysqldump (command line binary)

client_key
path
added in 2.0
The path to the client private key.

aliases: ssl_key
collation
-
Collation mode (sorting). This only applies to new table/databases and does not update existing ones, this is a limitation of MySQL.
config_file
path
added in 2.0
Default:
"~/.my.cnf"

connect_timeout
integer

Default:
[]
A list of table names that will be ignored in the dump of the form database_name.table_name
login_host
string
Default:
"localhost"
Host running the database.
login_password
string
The password used to authenticate with.
login_port
integer
Default:
3306

login_unix_socket

The path to a Unix domain socket for local connections.
login_user
string
The username used to authenticate with.
name
- / required
name of the database to add or remove
name=all May only be provided if state is dump or import.
if name=all Works like --all-databases option for mysqldump (Added in 2.0)

aliases: db
quick
boolean
added in 2.1
    Choices:
  • no
  • yes ←
Option used for dumping large tables
single_transaction
boolean
added in 2.1
    Choices:
  • no ←
  • yes
Execute the dump in a single transaction
state
-
    Choices:
  • present ←
  • absent
  • dump
  • import
The database state
target
-
Location, on the remote host, of the dump file to read from or write to. Uncompressed SQL files (.sql) as well as bzip2 (.bz2), gzip (.gz) and xz (Added in 2.0) compressed files are supported.

Notes

Note

  • Requires the mysql and mysqldump binaries on the remote host.
  • This module is not idempotent when state is import, and will import the dump file each time if run more than once.
  • Requires the PyMySQL (Python 2.7 and Python 3.X) or MySQL-python (Python 2.X) package on the remote host. The Python package may be installed with apt-get install python-pymysql (Ubuntu; see apt) or yum install python2-PyMySQL (RHEL/CentOS/Fedora; see yum). You can also use dnf install python2-PyMySQL for newer versions of Fedora; see dnf.
  • Both login_password and login_user are required when you are passing credentials. If none are present, the module will attempt to read the credentials from ~/.my.cnf, and finally fall back to using the MySQL default login of ‘root’ with no password.

Examples

- name: Create a new database with name 'bobdata'
  mysql_db:
    name: bobdata
    state: present

# Copy database dump file to remote host and restore it to database 'my_db'
- name: Copy database dump file
  copy:
    src: dump.sql.bz2
    dest: /tmp
- name: Restore database
  mysql_db:
    name: my_db
    state: import
    target: /tmp/dump.sql.bz2

- name: Dump all databases to hostname.sql
  mysql_db:
    state: dump
    name: all
    target: /tmp/{{ inventory_hostname }}.sql

- name: Import file.sql similar to mysql -u <username> -p <password> < hostname.sql
  mysql_db:
    state: import
    name: all
    target: /tmp/{{ inventory_hostname }}.sql
