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

Notes

Note

  • Requires the python-mysqldb package on the remote host, as well as mysql and mysqldump binaries.
  • Requires the MySQLdb Python package on the remote host. For Ubuntu, this is as easy as apt-get install python-mysqldb. (See apt.) For CentOS/Fedora, this is as easy as yum install MySQL-python. (See yum.)
  • 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.
