mysql MHA報錯 Can't exec "mysqlbinlog": No such file or directory at /usr/local/share/perl5/MHA/BinlogManager.pm line 99.

IT oca ilo 引入 cut found with while keepal

如果發現如下錯誤:

Can‘t exec "mysqlbinlog": No such file or directory at /usr/local/share/perl5/MHA/BinlogManager.pm line 99.
mysqlbinlog version not found!
Testing mysql connection and privileges..sh: mysql: command not found
mysql command failed with rc 127:0!

可以通過以下方法解決(在所有節點上執行):

還是報錯,糾結N久,才發現原因是:原來Failover兩種方式:一種是虛擬IP地址,一種是全局配置文件。MHA並沒有限定使用哪一種方式,而是讓用戶自己選擇,虛擬IP地址的方式會牽扯到其它的軟件,比如keepalive軟件,而且還要修改腳本master_ip_failover。


所以先暫時註釋master_ip_failover_script= /usr/local/bin/master_ip_failover這個選項。後面引入keepalived後和修改該腳本以後再開啟該選項

192.168.2.131 [root ~]$ grep master_ip_failover /etc/masterha/app1.cnf
#master_ip_failover_script= /usr/local/bin/master_ip_failover 

再次進行狀態查看:
