1、安装mysql 5.7.16
2、修改my.ini为

Python code

# 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]

default-character-set=utf8

port = 3306

[mysqld]

# Remove leading # and set to the amount of RAM for the most important data

# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.

# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging

# changes to the binary log between backups.

# log_bin

# These are commonly set, remove the # and set as required.

basedir = "D:\Program Files\MySQL\MySQL Server 5.7"

datadir = "D:\Program Files\MySQL\MySQL Server 5.7\data"

tmpdir = "D:\Program Files\MySQL\MySQL Server 5.7\data"

socket = "D:\Program Files\MySQL\MySQL Server 5.7\data\mysql.sock"

port = 3306

log-error = "D:\Program Files\MySQL\MySQL Server 5.7\data\mysql_error.log"

# server_id = .....

max_connections = 100

table_open_cache = 256

query_cache_size = 1M

tmp_table_size = 32M

thread_cache_size = 8

innodb_data_home_dir = "D:\Program Files\MySQL\MySQL Server 5.7\data\"

innodb_flush_log_at_trx_commit = 1

innodb_log_buffer_size = 128M

innodb_buffer_pool_size = 128M

innodb_log_file_size = 10M

innodb_thread_concurrency = 16

innodb-autoextend-increment = 1000

# Remove leading # to set options mainly useful for reporting servers.

# The server defaults are faster for transactions and fast SELECTs.

# Adjust sizes as needed, experiment to find the optimal values.

join_buffer_size = 128M

sort_buffer_size = 32M

read_rnd_buffer_size = 32M

max_allowed_packet = 32M

explicit_defaults_for_timestamp = true

sql_mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

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。
