All About MySQL Flush Privileges Ansible

Ansible includes the “mysql_flush” module which helps flush the privileges for a MySQL user. Furthermore, this module is used in Ansible playbooks in order to automate the configuration as well as the management of MySQL databases.

According to our experts, the mysql_flush module sends the “FLUSH PRIVILEGES” command to the MySQL server in order to reload the grant tables. This makes sure that changes made to the MySQL user privileges take effect immediately.

The changes made each time a MySQL user is created or its privileges are modified are stored in the grant tables. Furthermore, these tables are then read by the MySQL server when the user tries to connect to the database. The server relies on the information in these tables to authenticate the user as well as decide which actions are authorized.

Our experts would like to point out that the server does not immediately pick up on those changes. In fact, sometimes the changes take effect only after the server is restarted. This is where the “FLUSH PRIVILEGES” command comes in handy.

About the FLUSH PRIVILEGES Command

The FLUSH PRIVILEGES command informs the MySQL server to reload the grant tables. Hence, any changes made to the tables are applied immediately. As a result, users are authenticated and authorized correctly, and they have access to the data they need.

The FLUSH PRIVILEGES command is sent by the mysql_flush module in Ansible to the MySQL server to reload the grant tables. When we use this module in an Ansible playbook, we have to mention the MySQL user name for which we want to flush privileges. Furthermore, we have to include the login credentials for the MySQL server administrator as well.

For instance:

Here is a quick look at how the mysql_flush module is used in an Ansible playbook:

- name: Flush privileges for user mysql_flush: login_user: root login_password: rootpassword user: bob_user

In the above example, the mysql_flush module flushes the privileges for the MySQL user “bob_user”. The “login_user” and “login_password” specify the credentials of the MySQL server administrator, who has the necessary privileges to execute the “FLUSH PRIVILEGES” command.

In other words, the “mysql_flush” module is a useful tool for automating the management of MySQL databases with Ansible. By automating the execution of the “FLUSH PRIVILEGES” command, we can ensure that all changes made to the MySQL user privileges are immediately applied and take effect, without any manual intervention.
