如果要设置成恢复后不抢占只需要加上一条语句

state MASTER 修改为 state BACKUP 

nopreempt  设置为不抢夺VIP

keepalived默认的日志文件保存在/var/log/messages，更改日志保存位置到/var/log/keepalived.log

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
