Keepalived日志分离配置

Keepalived日志默认是在系统日志下的/var/log/messages，此时我们可以对其进行日志分离，将Keepalived的日志单独写入至我们配置好的路径中

---

vi /etc/sysconfig/keepalived

KEEPALIVED_OPTIONS="-D -S 0 -d"

vi /etc/rsyslog.conf

#这里的0对应着上方配置的-S 0
local0.* /etc/keepalived/keepalived.log

重启rsyslog和Keepalived

systemctl restart rsyslog

/etc/init.d/keepalived restart

此时，keepalived日志就被分离了

tail -f /var/log/keepalived.log
