报错时机

使用了mycat，而不是单纯使用了mysql。

报错信息

ERROR 1129 (HY000): Host '1.23.22.18' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'

解决思路

网上搜索一大把解决方法，大同小异，都是flush host等等。

比如2013年的cnblogs

但是，首先做的，应该是检查下是不是用户或者端口粗心写错了。

解决方法

  • mysql端口3306改为mycat的端口8066即可
mysql -h1.23.22.18 -umyuser -p123456-P3306

mysql -umyuser -p123456-P8066
  • ip去掉
mysql -h1.23.22.18 -uroot -p123456-P3306

mysql -uroot -p123456-P3306
