LVS日志 默认，keeplived也是把默认的日志写在messages，这TM很鼓励人啊，随后Google
1.在主从keeplived节点上vim/etc/sysconfig/keepalived文件
#vi /etc/sysconfig/keepalived
# Options for keepalived. See `keepalived --help' output andkeepalived(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-checkersubsystem.
# --dont-release-vrrp -V Dont remove VRRP VIPs &VROUTEs on daemon stop.
# --dont-release-ipvs -I Dont remove IPVS topology ondaemon stop.
# --dump-conf -d Dump the configuration data.
# --log-detail -D Detailed log messages.
# --log-facility -S 0-7 Set local syslogfacility (default=LOG_DAEMON)
#
#KEEPALIVED_OPTIONS="-D" #原配置文件
#KEEPALIVED_OPTIONS="-D -d -S 0"
KEEPALIVED_OPTIONS="-D -d -S 0" #修改成现在的配置
##参数解释都在#注释里面
2. 修改主从节点日志配置文件/etc/rsyslog.conf
#touch /var/log/keepalived.log
#vi /etc/rsyslog.conf
加入如下配置：
#keepalived -S 0
local0.* /var/log/keepalived.log
3.重启日志服务
# /etc/init.d/rsyslog restart
# /etc/init.d/keepalived restart
4.检查/var/log/keepalived.log文件是否存在
# cat /var/log/keepalived.log
LVS的日志文件在可以从/var/log/message从得到.从这里你可以得到你在运行lvs各种服务时是否有报错信息,以及错误的来源与故障点,这个文件是系统排错时的理想助手.建议经常使用,方便排错与日常维护.
查看：tail -f /var/log/message
