把日志单独存放
修改/etc/sysconfig/keepalived
把KEEPALIVED_OPTIONS="-D" 修改为：KEEPALIVED_OPTIONS="-D -d -S 0"
[root@lb01 /]# vim /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"
在/etc/rsyslog.conf 末尾添加
[root@lb01 /]# vim /etc/rsyslog.conf local0.* /var/log/keepalived.log
