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.
