Here's a short explanation of the configuration directives.
mysql.allow_persistent boolean
Whether to allow persistent connections to MySQL.
mysql.max_persistent integer
The maximum number of persistent MySQL connections per process.
mysql.max_links integer
The maximum number of MySQL connections per process, including
persistent connections.
mysql.default_port string
The default TCP port number to use when connecting to the
database server if no other port is specified. If no default
is specified, the port will be obtained from the MYSQL_TCP_PORT
environment variable, the mysql-tcp entry in /etc/services
or the compile-time MYSQL_PORT constant, in that order.
Win32 will only use the MYSQL_PORT constant.
mysql.default_socket string
The default socket name to use when connecting to a local
database server if no other socket name is specified.
mysql.default_host string
The default server host to use when connecting to the database
server if no other host is specified. Doesn't apply in safe
mode.
mysql.default_user string
The default user name to use when connecting to the database
server if no other name is specified. Doesn't apply in safe
mode.
mysql.default_password string
The default password to use when connecting to the database
server if no other password is specified. Doesn't apply
in safe mode.
mysql.connect_timeout integer
Connect timeout in seconds. On Linux this timeout is also
used for waiting for the first answer from the server.
