Module to provide MySQL compatibility to salt.

|
---|
Note
On CentOS 5 (and possibly RHEL 5) both MySQL-python and python26-mysqldb need to be installed.
configuration: | In order to connect to MySQL, certain configuration is required in /etc/salt/minion on the relevant minions. Some sample configs might look like: mysql.host: 'localhost'
mysql.port: 3306
mysql.user: 'root'
mysql.pass: ''
mysql.db: 'mysql'
mysql.unix_socket: '/tmp/mysql.sock'
mysql.charset: 'utf8'
You can also use a defaults file: mysql.default_file: '/etc/mysql/debian.cnf'

Changed in version 2014.1.0: (Hydrogen) charset connection argument added. This is a MySQL charset, not a python one
Changed in version 0.16.2: Connection arguments from the minion config file can be overridden on the CLI by using the arguments defined here. Additionally, it is now possible to setup a user with no password.
Repairs the full database or just a given table

salt '*' mysql.db_check dbname
salt '*' mysql.db_check dbname dbtable

salt '*' mysql.db_create 'dbname'
salt '*' mysql.db_create 'dbname' 'utf8' 'utf8_general_ci'
Checks if a database exists on the MySQL server.
CLI Example:
salt '*' mysql.db_exists 'dbname'
Return a list of databases of a MySQL server using the output from the SHOW DATABASES query.

salt '*' mysql.db_list
Optimizes the full database or just a given table
CLI Example:
salt '*' mysql.db_optimize dbname
Removes a databases from the MySQL server.
CLI Example:
salt '*' mysql.db_remove 'dbname'
Repairs the full database or just a given table
CLI Example:
salt '*' mysql.db_repair dbname
Shows the tables in the given MySQL database (if exists)
CLI Example:
salt '*' mysql.db_tables 'database'
Frees a slave from its master. This is a WIP, do not use.
CLI Example:
salt '*' mysql.free_slave
Retrieves the master status from the minion.
CLI Example:
salt '*' mysql.get_master_status
Retrieves the slave status from the minion.

CLI Example:
salt '*' mysql.get_slave_status
Adds a grant to the MySQL server.
For database, make sure you specify database.table or database.*
CLI Example:
salt '*' mysql.grant_add 'SELECT,INSERT,UPDATE,...' 'database.*' 'frank' 'localhost'
Checks to see if a grant exists in the database
CLI Example:
salt '*' mysql.grant_exists 'SELECT,INSERT,UPDATE,...' 'database.*' 'frank' 'localhost'
Removes a grant from the MySQL server.
CLI Example:
salt '*' mysql.grant_revoke 'SELECT,INSERT,UPDATE' 'database.*' 'frank' 'localhost'
Retrieves the processlist from the MySQL server via "SHOW FULL PROCESSLIST".
CLI Example:
salt '*' mysql.processlist
Run an arbitrary SQL query and return the results or the number of affected rows.
CLI Example:
salt '*' mysql.query mydb "UPDATE mytable set myfield=1 limit 1"
Return data:
{'query time': {'human': '39.0ms', 'raw': '0.03899'}, 'rows affected': 1L}
CLI Example:
salt '*' mysql.query mydb "SELECT id,name,cash from users limit 3"
Return data:
{'columns': ('id', 'name', 'cash'),
'query time': {'human': '1.0ms', 'raw': '0.001'},
'results': ((1L, 'User 1', Decimal('110.000000')),
(2L, 'User 2', Decimal('215.636756')),
(3L, 'User 3', Decimal('0.040000'))),
'rows returned': 3L}
CLI Example:
salt '*' mysql.query mydb 'INSERT into users values (null,"user 4", 5)'
Return data:
{'query time': {'human': '25.6ms', 'raw': '0.02563'}, 'rows affected': 1L}
CLI Example:
salt '*' mysql.query mydb 'DELETE from users where id = 4 limit 1'
Return data:
{'query time': {'human': '39.0ms', 'raw': '0.03899'}, 'rows affected': 1L}
Jinja Example: Run a query on mydb and use row 0, column 0's data.
{{ salt['mysql.query']('mydb', 'SELECT info from mytable limit 1')['results'][0][0] }}
Return an identifier name (column, table, database, etc) escaped for MySQL
This means surrounded by "`" character and escaping this charater inside. It also means doubling the '%' character for MySQLdb internal usage.
Parameters: |

CLI Example:
salt '*' mysql.quote_identifier 'foo`bar'
Retrieves the show global variables from the minion.
CLI Example:
salt '*' mysql.showglobal
Retrieves the show variables from the minion.
CLI Example:
salt '*' mysql.showvariables
Return the number of seconds that a slave SQL server is lagging behind the master, if the host is not a slave it will return -1. If the server is configured to be a slave for replication but slave IO is not running then -2 will be returned. If there was an error connecting to the database or checking the slave status, -3 will be returned.
CLI Example:
salt '*' mysql.slave_lag
Return the status of a MySQL server using the output from the SHOW STATUS query.

Change password for a MySQL user
The password in hashed form. Be sure to quote the password because YAML doesn't like the *. A password hash can be obtained from the mysql command-line client like so:
mysql> SELECT PASSWORD('mypass');
+-------------------------------------------+
| PASSWORD('mypass') |
+-------------------------------------------+
| *6C8989366EAF75BB670AD8EA7A7FC1176A95CEF4 |
+-------------------------------------------+
1 row in set (0.00 sec)
New in version 0.16.2: The allow_passwordless option was added.
CLI Examples:
salt '*' mysql.user_chpass frank localhost newpassword
salt '*' mysql.user_chpass frank localhost password_hash='hash'
salt '*' mysql.user_chpass frank localhost allow_passwordless=True
Creates a MySQL user
The password in hashed form. Be sure to quote the password because YAML doesn't like the *. A password hash can be obtained from the mysql command-line client like so:

salt '*' mysql.user_create 'username' 'hostname' password_hash='hash'
salt '*' mysql.user_create 'username' 'hostname' allow_passwordless=True
Checks if a user exists on the MySQL server. A login can be checked to see if passwordless login is permitted by omitting password and password_hash, and using passwordless=True.
New in version 0.16.2: The passwordless option was added.

salt '*' mysql.user_exists 'username' 'hostname' 'password'
salt '*' mysql.user_exists 'username' 'hostname' password_hash='hash'
