DESCRIPTION

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

OPTIONS

28        -f, --use-file=FILE
29              Use the specified configuration file. The default configuration
30              file is "/etc/keepalived/keepalived.conf".
31
32        -P, --vrrp
33              Only run the VRRP subsystem. This is useful for configurations
34              that do not use IPVS load balancer.
35
36        -C, --check
37              Only run the healthcheck subsystem. This is useful for
38              configurations that use the IPVS load balancer with a single
39              director with no failover.
40
41        -l, --log-console
42              Log messages to the local console. The default behavior is to
43              log messages to syslog.
44
45        -D, --log-detail
46              Detailed log messages.
47
48        -S, --log-facility=[0-7]
49              Set syslog facility to LOG_LOCAL[0-7]. The default syslog
50              facility is LOG_DAEMON.
51
52        -V, --dont-release-vrrp
53              Don't remove VRRP VIPs and VROUTEs on daemon stop. The default
54              behavior is to remove all VIPs and VROUTEs when keepalived exits
55
56        -I, --dont-release-ipvs
57              Don't remove IPVS topology on daemon stop. The default behavior
58              it to remove all entries from the IPVS virtual server table on
59              when keepalived exits.
60
61        -R, --dont-respawn
62              Don't respawn child processes. The default behavior is to
63              restart the VRRP and checker processes if either process exits.
64
65        -n, --dont-fork
66              Don't fork the daemon process. This option will cause keepalived
67              to run in the foreground.
68
69        -d, --dump-conf
70              Dump the configuration data.
71
72        -p, --pid=FILE
73              Use specified pidfile for parent keepalived process. The default
74              pidfile for keepalived is "/var/run/keepalived.pid".
75
76        -r, --vrrp_pid=FILE
77              Use specified pidfile for VRRP child process. The default
78              pidfile for the VRRP child process is
79              "/var/run/keepalived_vrrp.pid".
80
81        -c, --checkers_pid=FILE
82              Use specified pidfile for checkers child process. The default
83              pidfile for the checker child process is
84              "/var/run/keepalived_checkers.pid".
85
86        -x, --snmp
87              Enable SNMP subsystem.
88
89        -v, --version
90              Display the version and exit.
91
92        -h, --help
93              Display this help message and exit.
