keepalived指定日志文件

首先查看keepalived命令的参数，-S指定syslog的facility。

/usr/local/keepalived/sbin/keepalived --vrrp               -P    Only run with VRRP subsystem.
/usr/local/keepalived/sbin/keepalived --check              -C    Only run with Health-checker subsystem.
/usr/local/keepalived/sbin/keepalived --dont-release-vrrp  -V    Dont remove VRRP VIPs & VROUTEs on daemon stop.
/usr/local/keepalived/sbin/keepalived --dont-release-ipvs  -I    Dont remove IPVS topology on daemon stop.
/usr/local/keepalived/sbin/keepalived --dont-fork          -n    Dont fork the daemon process.
/usr/local/keepalived/sbin/keepalived --use-file           -f    Use the specified configuration file.
                              Default is /etc/keepalived/keepalived.conf.
/usr/local/keepalived/sbin/keepalived --dump-conf          -d    Dump the configuration data.
/usr/local/keepalived/sbin/keepalived --log-console        -l    Log message to local console.
/usr/local/keepalived/sbin/keepalived --log-detail         -D    Detailed log messages.
/usr/local/keepalived/sbin/keepalived --log-facility       -S    0-7 Set syslog facility to LOG_LOCAL[0-7]. (default=LOG_DAEMON)
/usr/local/keepalived/sbin/keepalived --help               -h    Display this short inlined help screen.
/usr/local/keepalived/sbin/keepalived --version            -v    Display the version number
/usr/local/keepalived/sbin/keepalived --pid                -p    pidfile
/usr/local/keepalived/sbin/keepalived --checkers_pid       -c    checkers pidfile
/usr/local/keepalived/sbin/keepalived --vrrp_pid           -r    vrrp pidfile

然后通过如下命令启动keepalived，

[root@LVS02 ~]# /usr/local/keepalived/sbin/keepalived -d -D -S 0

或者修改/etc/sysconfig/keepalived，然后用service来启动。

[root@LVS02 ~]# cat /etc/sysconfig/keepalived
# Options for keepalived. See `keepalived --help' output and keepalived(8) and
# keepalived.conf(5) man pages for a list of all options. Here are the most
# common ones :
#
# --vrrp               -P    Only run with VRRP subsystem.
# --check              -C    Only run with Health-checker subsystem.
# --dont-release-vrrp  -V    Dont remove VRRP VIPs & VROUTEs on daemon stop.
# --dont-release-ipvs  -I    Dont remove IPVS topology on daemon stop.
# --dump-conf          -d    Dump the configuration data.
# --log-detail         -D    Detailed log messages.
# --log-facility       -S    0-7 Set local syslog facility (default=LOG_DAEMON)
#

KEEPALIVED_OPTIONS="-D -d -S 0"

[root@LVS02 ~]# service keepalived start

最后设置syslog，修改/etc/syslog.conf.

root@LVS02 ~]# cat /etc/syslog.conf
# Log all kernel messages to the console.
# Logging much else clutters up the screen.
#kern.*                         /dev/console

# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none        /var/log/messages

# The authpriv file has restricted access.
authpriv.*                      /var/log/secure

# Log all the mail messages in one place.
mail.*                          -/var/log/maillog


# Log cron stuff
cron.*                          /var/log/cron

# Everybody gets emergency messages
*.emerg                         *

# Save news errors of level crit and higher in a special file.
uucp,news.crit                      /var/log/spooler

# Save boot messages also to boot.log
local7.*                        /var/log/boot.log

# keepalived -S 0
local0.*                                                /var/log/keepalived.log

重启syslog，设置完成。
