Mysql连接错误:Mysql Host is blocked because of many connection errors
环境:linux,mysql5.5.31错误:Host is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'
原因:
同一个ip在短时间内产生太多(超过mysql数据库max_connection_errors的最大值)中断的数据库连接而导致的阻塞;
解决方法:
1、提高允许的max_connection_errors数量(治标不治本):
① 进入Mysql数据库查看max_connection_errors: show variables like '%max_connect_errors%';
② 修改max_connection_errors的数量为1000: set global max_connect_errors = 1000;
③ 查看是否修改成功:show variables like '%max_connect_errors%';
2、使用mysqladmin flush-hosts 命令清理一下hosts文件(不知道mysqladmin在哪个目录下可以使用命令查找:whereis mysqladmin);
① 在查找到的目录下使用命令修改:/usr/bin/mysqladmin flush-hosts -h192.168.1.1 -P3308 -uroot -prootpwd;
备注:
其中端口号,用户名,密码都可以根据需要来添加和修改;
配置有master/slave主从数据库的要把主库和从库都修改一遍的(我就吃了这个亏明明很容易的几条命令结果折腾了大半天);
第二步也可以在数据库中进行,命令如下:flush hosts;
