mysql.server can be found in the support-files directory under your MariaDB installation directory or in a MariaDB source distribution.
If you use the Linux server RPM package (MySQL-server-VERSION.rpm), the mysql.server script will be installed in the /etc/init.d directory with the name mysql. You need not install it manually.
Some vendors provide RPM packages that install a startup script under a different name such as mysqld.
If you install MariaDB from a source distribution or using a binary distribution format that does not install mysql.server automatically, you can install it manually.
mysql.server reads options from the [mysql.server] and [mysqld] sections of option files. For backward compatibility, it also reads [mysql_server] sections, although you should rename such sections to [mysql.server]&.
mysql.server supports the following options.
The path to the MariaDB installation directory.
The path to the MariaDB data directory.
The path name of the file in which the server should write its process ID. If not provided, the default, "host_name.pid" is used.
How long in seconds to wait for confirmation of server startup. If the server does not start within this time, mysql.server exits with an error. The default value is 900. A value of 0 means not to wait at all for startup. Negative values mean to wait forever (no timeout).
Use mysqld_safe to start the server. This is the default.
Use Instance Manager to start the server.
The login user name to use for running mysqld.
