開始學python 交互MySQLdb，踩了很多坑
第一個
%d format: a number is required, not str
參照以下博客：
https://blog.csdn.net/u011878172/article/details/72599120
# -*- 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 進入資料庫
show variables like 'max_connect_errors';
查看最大連接數
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%';
解決方法2：使用mysqladmin flush-hosts 命令清理一下hosts文件
(1)在查找到的目錄下使用命令修改：mysqladmin -u xxx -p flush-hosts
或者
> flush hosts;
解決方法3：重啟mysqld
也可以在重啟之前，在配置文件中將該參數調大。
# vi /etc/my.cnf
max_connect_errors = 100
