aliases: ssl_cert
client_key
path
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
Default:
"~/.my.cnf"

connect_timeout
integer
Default:

login_host
string
Default:
"localhost"
Host running the database.
login_password

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

aliases: db
quick
boolean
    Choices:
  • no
  • yes ←
Option used for dumping large tables
single_transaction
boolean
    Choices:
  • no ←
  • yes
Execute the dump in a single transaction
state
-
    Choices:
  • present ←
  • absent
  • dump
  • import
The database state
target
-

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

- name: Create new databases with names 'foo' and 'bar'
  mysql_db:
    name:
      - foo
      - bar
    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 multiple databases
  mysql_db:
    state: dump
    name: db_1,db_2
    target: /tmp/dump.sql

- name: Dump multiple databases
  mysql_db:
    state: dump
    name:
      - db_1
      - db_2
    target: /tmp/dump.sql

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

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

- name: Delete database with name 'bobdata'
  mysql_db:
    name: bobdata
    state: absent

- name: Make sure there is neither a database with name 'foo', nor one with name 'bar'
  mysql_db:
    name:
      - foo
      - bar
    state: absent
