【交流】keepalived告警交流

Ly_stu

   基于的keepalived 的主主（双ip）做了nginx的高可用性， 检测keepalived主备状态改态改变，然后通过

1. notify_master "/usr/local/keepalived/etc/keepalived/notify1.sh master"
   
2. notify_backup "/usr/local/keepalived/etc/keepalived/notify1.sh backup"
   
3. notify_stop"/usr/local/keepalived/etc/keepalived/notify1.sh stop"

复制代码

只是 感觉时不时 会收到告警 提示，”A主机切换为master，马上就会切换为backup“
  日志信息如下：
  
  什么会导致这种情况产生呢，网络连接状况吗 并且主备切换 也配置了延迟，延迟时间为30秒，

你的Nginx监听的IP地址是什么？对外的vip的地址吗？

Ly_stu

嗯 是的
你指的 侦听配置是是

附上一个node的 配置keepalived.conf代码

能不能把你的Nginx的配置贴一下啊？
   

Ly_stu

nginx的配置很简单，设置一个server{} 根据upstream{} 进行分配给后端，
