修改keepalived日志路径

keepalived默认的日志文件保存在/var/log/messages，直接在控制台输入/var/log/messages 报没有权限，tail /var/log/messages 则没有打印keepalived相关日志，所以重定向keepalived的日志路径。

1.vim  /etc/sysconfig/keepalived  将文件的这一行 KEEPALIVED_OPTIONS="-D" 修改为      KEEPALIVED_OPTIONS="-D -d -S 0"

2.vim /etc/rsyslog.conf 在文件的最后添加一行

   local0.*     /var/log/keepalived.log

3.重启rsyslog服务  systemctl restart  rsyslog

4.重启keepalived服务，日志会打印到/var/log/keepalived.log
