![]() How do I secure my MySQL or MariaDB server against failure? (German only).Create and delete a MySQL database (German only).Use the following command: DROP USER sure you have reloaded the privileges after every change to the revision tables. The exact syntax is very well described in the documentation of MySQL. GRANT OPTION: Allows a user to set or revoke the rights of other users SELECT: Read permissions for a database or table INSERT: Allows a user to create new rows in a table * – to all databasesĬREATE: Allows a user to create new databasesĭELETE: Allows a user to delete individual rows in a table ALL PRIVILEGES: A wildcard for all rights to the selected database object or – with a *.In addition to the ‘ALL PRIVILEGES’ used above, you can also assign other sets of privileges to a user in your MySQL server. If you forget the command, it is possible that you cannot register with the new (or changed) access data to the database server yet. To update the copy of the privileges in the memory, you should run the command: FLUSH PRIVILEGES MySQL usually holds the user access rights in memory, hence slow I / O operations do not have to happen every time a user logs on to the database. – TO : This is the user who is going to receive these rights. * ‘To grant a user, for example, all rights, or the restriction to individual tables of a database, e.g. * : This specifies the areas to which the rights are to be assigned. There are also limited privileges, more about that later. – GRANT ALL PRIVILEGES : All available privileges (rights) are assigned. * TO short explanation of the commands above: Replace the value “user” with your own user name: GRANT ALL PRIVILEGES ON myDB. CREATE DATABASE 'myDB' Īnd now grant your new user all rights to this database. ![]() For test purposes create a new database, which the user may access later. You have created a user who does not have any permissions on any database or table yet. Just replace the values “user” and “password” in the following command: CREATE USER IDENTIFIED BY 'password' Type '\c' to clear the current input statement.Ĭreating a new user is comparatively easy.

If you have not set a password, do so without the parameter ‘-p’ and you will not be asked for a password. ![]() After the input you should see the MySQL prompt.

Even if only MySQL is mentioned in this article, all commands can be transferred to MariaDB one-to-one. This short article is about creating a new user and giving him rights to a database. A very fine-grained access rights system helps you controlling the access of different users. With these databases, you can dynamically store and manage large amounts of data. Dockerfile-mysqlĭocker run -d -name custom-mysql-container -p 127.0.0.MySQL and MariaDB are probably the most popular OpenSource database management systems. schemapath/privileges.sql /docker-entrypoint-initdb.d/įinally, execute below docker comments to create a custom MySQL image and run it as a container in detached mode. Privileges.sql CREATE USER IDENTIFIED BY 'readonly' ĬOPY. For the generic purpose, I have used % (any valid host) Additionally, As you have started with -skip-name-resolve mode, MySQL does not consider the DNS lookup values and look for IP address which is default 127.0.0.1. I have included my working code snippets which would suffice for the requirement, just modify the SQL in the privileges.sql file as per your need. All SQL files inside /docker-entrypoint-initdb.d/ the directory would be executed by default when MySQL container boots. I have created a SQL script and copy to a folder /docker-entrypoint-initdb.d/ inside an image. I have got into the same situation, in my case I have to start my standard MySQL container with readonly user with SELECT only privilege.
