如何重定向Keepalived日志的输出路径

Keepalived默认所有的日志都是写入到/var/log/message下的，由于message的日志太多了，而Keepalived的日志又很难分离出来，所以本文提供了一个调整Keepalived日志输出路径的方法。
具体操作步骤如下：
一、修改 /etc/sysconfig/keepalived
把KEEPALIVED_OPTIONS="-D" 修改为KEEPALIVED_OPTIONS="-D -d -S 0"
#其中-S指定syslog的facility
二、重启服务
service keepalived restart
三、设置syslog，修改/etc/syslog.conf，添加内容如下
# keepalived -S 0 
local0.*                    /var/log/keepalived.log
注意：local0是l是字符L的小写
四、Keepalived相关管理的知识拓展
/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
