keepalived
KEEPALIVED(8) System Manager's Manual KEEPALIVED(8)
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.
