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。
