NAME
       keepalived - load-balancing and high-availability service

SYNOPSIS
       keepalived [-f|--use-file=FILE] [-P|--vrrp] [-C|--check] [-l|--log-console] [-D|--log-detail] [-S|--log-facility={0-7}]
       [-V|--dont-release-vrrp] [-I|--dont-release-ipvs] [-R|--dont-respawn] [-n|--dont-fork] [-d|--dump-conf] [-p|--pid=FILE]
       [-r|--vrrp_pid=FILE] [-c|--checkers_pid=FILE] [-v|--version] [-h|--help]

DESCRIPTION
       Keepalived provides simple and robust facilities for load-balancing and high-availability. The load-balancing framework relies on
       well-known and widely used Linux Virtual Server (IPVS) kernel module providing Layer4 load-balancing. Keepalived implements a set of
       checkers to dynamically and adaptively maintain and manage load-balanced server pool according their health. Keepalived also implements the
       VRRPv2 protocol to achieve high-availability with director failover.

OPTIONS
	-f, --use-file=FILE
	      Use the specified configuration file. The default configuration file is "/etc/keepalived/keepalived.conf".

	-P, --vrrp
	      Only run the VRRP subsystem. This is useful for configurations that do not use IPVS load balancer.

	-C, --check
	      Only run the healthcheck subsystem. This is useful for configurations that use the IPVS load balancer with a single director with no
	      failover.

	-l, --log-console
	      Log messages to the local console. The default behavior is to log messages to syslog.

	-D, --log-detail
	      Detailed log messages.

	-S, --log-facility=[0-7]
	      Set syslog facility to LOG_LOCAL[0-7]. The default syslog facility is LOG_DAEMON.

	-V, --dont-release-vrrp
	      Don't remove VRRP VIPs and VROUTEs on daemon stop. The default behavior is to remove all VIPs and VROUTEs when keepalived exits

	-I, --dont-release-ipvs
	      Don't remove IPVS topology on daemon stop. The default behavior it to remove all entries from the IPVS virtual server table on when
	      keepalived exits.

	-R, --dont-respawn
	      Don't respawn child processes. The default behavior is to restart the VRRP and checker processes if either process exits.

	-n, --dont-fork
	      Don't fork the daemon process. This option will cause keepalived to run in the foreground.

	-d, --dump-conf
	      Dump the configuration data.

	-p, --pid=FILE
	      Use specified pidfile for parent keepalived process. The default pidfile for keepalived is "/var/run/keepalived.pid".

	-r, --vrrp_pid=FILE
	      Use specified pidfile for VRRP child process. The default pidfile for the VRRP child process is "/var/run/keepalived_vrrp.pid".

	-c, --checkers_pid=FILE
	      Use specified pidfile for checkers child process. The default pidfile for the checker child process is
	      "/var/run/keepalived_checkers.pid".

	-v, --version
	      Display the version and exit.

	-h, --help
	      Display this help message and exit.
