【交流】keepalived告警交流

Ly_stu

   基于的keepalived 的主主（雙ip）做了nginx的高可用性， 檢測keepalived主備狀態(tài)改態(tài)改變，然后通過

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"

復(fù)制代碼

只是 感覺時(shí)不時(shí) 會(huì)收到告警 提示，”A主機(jī)切換為master，馬上就會(huì)切換為backup“
  日志信息如下：
  
  什么會(huì)導(dǎo)致這種情況產(chǎn)生呢，網(wǎng)絡(luò)連接狀況嗎 并且主備切換 也配置了延遲，延遲時(shí)間為30秒，

你的Nginx監(jiān)聽的IP地址是什么？對(duì)外的vip的地址嗎？

Ly_stu

嗯 是的
你指的 偵聽配置是是

能不能把你的Nginx的配置貼一下��？
   

Ly_stu

nginx的配置很簡單，設(shè)置一個(gè)server{} 根據(jù)upstream{} 進(jìn)行分配給后端，
