1、安装mysql 5.7.16
2、修改my.ini为
Python code
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 | # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL. [client]

3、下载mysql 5.6.27,并解压
4、拷贝其中的data文件夹中的mysql文件夹至5.7.16版本的对应位置
5、安装mysql-connector-odbc-noinstall-5.3.6-winx64
6、用root登陆mysql一切正常;添加root密码,再次用root加密码登陆,失败,显示“”error 1524: plugin ... in not loaded"
7、在my.ini中添加了skip-grant-tables,然后不用密码登陆root
8、mysql>use mysql;
9、mysql>update user set password=PASSWORD("123456") where user='root';
10、修改成功,再次root加密码登陆,失败,还是同样的问题
11、在my.ini中添加了skip-grant-tables,然后不用密码登陆root。mysql> SELECT Host,User,Password,plugin from user;发现plugin参数不是“mysql_native_password”
12、update user set plugin='mysql_native_password';搞定。
