MySql报错:unblock with ‘mysqladmin flush-hosts

信息排查

# 查看最大错误连接数限制
show global variables like 'max_connect_errors';

# 查看连接IP
select * from performance_schema.host_cache

 # 刷新数据库IP缓存 
flush hosts


 # 查看连接
SELECt substring_index(host, ':',1) AS host_name, state, count(*) FROM information_schema.processlist GROUP BY state, host_name;

解决:进入数据库 使用admin权限账号

1、将变量max_connection_errors的值设置为一个更大的值

set global max_connect_errors=1500;


2、执行命令使用flush hosts


3、改变系统变量值是的让MySQL服务器不记录host cache信息（不建议）如：set global host_cache_size=0;
