pymysql 操作数据库 (含使用socket连接数据库的方法)

db = pymysql.connect(host="127.0.0.1", user="root",password="root", db="mysql", port=3306, charset='utf8',unix_socket="/Applications/MAMP/tmp/mysql/mysql.sock")

connect里面的参数参考: https://www.jianshu.com/p/4850afe7098f

unix_socket为使用socket登录，我用mamp中的phpmyadmin 有给的

 

正常链接

db = pymysql.connect("数据库地址","账号","密码","库名")

例子:

一:

#连接测试数据库数据库
db = pymysql.connect("数据库地址","账号","密码","访问的数据库")      ##这里这样默认填可能会说传入参数过多的解决方法 https://www.cnblogs.com/kaibindirver/p/14425482.html

二: 使用socket连接

db = pymysql.connect(host="127.0.0.1", user="root",password="root", db="访问的数据库", port=3306, charset='utf8',unix_socket="/Applications/MAMP/tmp/mysql/mysql.sock")
