# PROVIDE: mysqlrouter
# REQUIRE: LOGIN
# KEYWORD: shutdown

#
# Add the following lines to /etc/rc.conf to enable mysqlrouter:
#
# mysqlrouter_enable (bool):	Set to "NO" by default.
#				Set it to "YES" to enable mysqlrouter.
# mysqlrouter_config (str):	Configuration file.
#				Default "%%PREFIX%%/etc/mysqlrouter/mysqlrouter.conf".
# mysqlrouter_user (str):	User to run mysqlrouter as, handled by rc.subr.
#				Default "mysqlrouter".
# mysqlrouter_group (str):	Group of the runtime, log and data directory.
#				Default "mysqlrouter".
# mysqlrouter_login_class (str):	Login class, see rc.subr(8) and
#				login.conf(5).  Raise openfiles there when the
#				router has to serve many connections, upstream
#				uses 10000.  Default "daemon".
# mysqlrouter_rundir (str):	Runtime directory. Must match "runtime_folder"
#				in the configuration file and the path used by
#				%%PREFIX%%/etc/logrotate.d/mysqlrouter.
#				Default "/var/run/mysqlrouter".
# mysqlrouter_logdir (str):	Log directory. Must match "logging_folder".
#				Default "/var/log/mysqlrouter".
# mysqlrouter_datadir (str):	Data directory, holds the keyring and the
#				dynamic state. Must match "data_folder".
#				Default "/var/db/mysqlrouter".
# mysqlrouter_args (str):	Custom additional arguments (default empty).
#
# mysqlrouter does not detach itself, so it is run under daemon(8).  The PID
# file is written by daemon(8), not by mysqlrouter.  Do not add a "pid_file"
# entry to the configuration file, mysqlrouter would then refuse to start
# with "PID file ... found. Already running?".
