10.3. Booleans
SELinux is based on the least level of access required for a service to run. Services can be run in a variety of ways; therefore, you must tell SELinux how you are running services. The following Boolean allows you to tell SELinux how you are running MySQL:
allow_user_mysql_connect
When enabled, this Boolean allows users to connect to MySQL.
exim_can_connect_db
When enabled, this Boolean allows the exim mailer to initiate connections to a database server.
ftpd_connect_db
When enabled, this Boolean allows ftp daemons to initiate connections to a database server.
httpd_can_network_connect_db
Enabling this Boolean is required for a web server to communicate with a database server.
