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".

-x, –snmp

Enable SNMP subsystem.

-v, –version

Display the version and exit.

-h, –help

Display this help message and exit.
