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. SEE ALSO
