开始学python 交互MySQLdb,踩了很多坑
第一个
%d format: a number is required, not str
解决方法:
# -*- coding: utf-8 -*- import MySQLdb try: conn=MySQLdb.connect(host='localhost',port='3306',db='test',user='root',passwd='toor',charset='utf-8') csl=conn.cursor() count=csl.execute("inser into stu(stu_id,stu_name,stu_phone,stu_hometown) values('0003','kj','19564832601',河北)") print count conn.commit() csl.close() conn.close() except Exception,e: print e.message an integer is required (got type str) port=3306
即可
(1129, "Host '192.168.65.1' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'")
mysql -u root -p 进入数据库
show variables like 'max_connect_errors';
查看最大连接数
set global max_connect_errors = 1000;
修改max_connect_errors的值:
(3)查看是否修改成功
> show variables like '%max_connect_errors%';
解决方法2:使用mysqladmin flush-hosts 命令清理一下hosts文件
(1)在查找到的目录下使用命令修改:mysqladmin -u xxx -p flush-hosts
或者
> flush hosts;
解决方法3:重启mysqld
也可以在重启之前,在配置文件中将该参数调大。
# vi /etc/my.cnf max_connect_errors = 100
