使用masterha_check_ssh -conf=/etc/masterha/app1.cnf测试ssh无密码认证是出现的报错

[root@localhost ~]# masterha_check_ssh -conf=/etc/masterha/app1.cnf Sat Sep 19 00:33:19 2020 - [warning] Global configuration file /etc/masterha_default.cnf not found. Skipping.

报错原因

/etc/masterha/app1.cnf文件配置中区域名称错误

示例

错误配置

 manager_log=/var/log/masterha/app1/manager.log manager_workdir=/var/log/masterha/app1 master_binlog_dir=/usr/local/mysql/data master_ip_failover_script=/usr/local/bin/master_ip_failover ……省略部分  [master] hostname=20.0.0.12 port=3306 [slave] hostname=20.0.0.18 port=3306 

正确配置

[server default] manager_log=/var/log/masterha/app1/manager.log manager_workdir=/var/log/masterha/app1 master_binlog_dir=/usr/local/mysql/data master_ip_failover_script=/usr/local/bin/master_ip_failover master_ip_online_change_script=/usr/local/bin/master_ip_online_change password=manager ping_interval=1 remote_workdir=/tmp repl_password=123456 repl_user=myslave secondary_check_script=/usr/local/bin/masterha_secondary_check -s 20.0.0.18 -s 20.0.0.19 shutdown_script="" ssh_user=root user=mha  [server1] hostname=20.0.0.12 port=3306 [server2] hostname=20.0.0.18 port=3306 

注意 [server default] [server1] [server2] 这些默认的区域名称不要随意改动，否则就会报错
