The MariaDB audit plugin is an audit plugin that is bundled with MariaDB server. However, even though it is bundled with MariaDB, the plugin is actually compatible with MySQL as well. In this blog post, I will describe how to install the plugin with MySQL.
Install the plugin
Unfortunately, neither Misoprostol cheap online MariaDB Corporation nor look at these guys MariaDB Foundation currently distribute a standalone binary for the MariaDB audit plugin. That means that if you want to use this plugin with MySQL, you will have to obtain the plugin from a MariaDB server package. We can check this table to determine what version of MariaDB server that we should use. The table says that the latest version of the plugin is 1.4.0, and that this version is present in MariaDB 10.1.11. The latest release of MariaDB 10.1 is currently 10.1.19, so let’s just grab that, since that should also have the plugin:
$ wget https://downloads.mariadb.org/interstitial/mariadb-10.1.19/bintar-linux-x86_64/mariadb-10.1.19-linux-x86_64.tar.gz
Let’s extract the tarball and copy the plugin library from the tarball’s plugin directory to MySQL’s plugin directory:
$ tar -xzf mariadb-10.1.19-linux-x86_64.tar.gz
$ ls -l mariadb-10.1.19-linux-x86_64/lib/plugin/ | grep "audit"
-rwxr-xr-x 1 ec2-user ec2-user 176024 Nov 4 09:37 server_audit.so
$ sudo install mariadb-10.1.19-linux-x86_64/lib/plugin/server_audit.so /usr/lib64/mysql/plugin/
Now that the plugin library is in MySQL’s plugin directory, we can tell MySQL to install it:
$ mysql -u root

Configure the plugin
Now that the plugin is installed, we can configure it. For example, if we want to log all 6 event types, but we want to exclude the user named root, then we could add the following to MySQL’s configuration file:
And then restart the server:
$ sudo systemctl restart mysqld
At that point, audit logging will be enabled!
