MHA问题

#解决办法:

vim /etc/my.cnf
[mysqld]#mysql5.6
skip-name-resolve
skip-name-resolv
#mysql5.7
skip_name_resolve

/etc/init.d/mysqld restart

 

#碰到这个问题,是因为创建私钥公钥的问题, 解决办法:

[root@node1 .ssh]#  cd /root/.ssh/

[root@node1 .ssh]#  rm -rf *

然后重新创建私钥公钥

#在主节点的mysql 内添加:

grant replication slave on *.* to rep@'%' identified by '123';

 CHANGE MASTER TO MASTER_HOST='10.0.0.51', MASTER_PORT=3306, MASTER_LOG_FILE='mysql-bin.000008', MASTER_LOG_POS=120, MASTER_USER='rep', MASTER_PASSWORD='xxx';
