1、安装mysql 5.7.16
2、修改my.ini为

# 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

##################### @wangjian0228 感谢回复。 ##################### .err错误日志如下：链接：http://pan.baidu.com/s/1c2OdQoC 密码：yu7n。用户创建规则http://dev.mysql.com/doc/refman/5.7/en/create-user.html看了一上午，已经聚焦于mysql_native_password，但是还不会实操。索性就加了skip-grant-tables裸奔。 ##################### @yupeigu 感谢回复。 ##################### 应该是你提到的问题，但是具体怎么修改为mysql_native_password呢？代码如下：

mysql> select user,password,plugin from user;
