1.  mysql官网: 下载

2.在windows系统环境变量path,加入如下内容

D:\mysql\mysql-5.7.5-m15-winx64\bin;(注意加分号)

3.在D:\Program Files (x86)\mysql-5.7.9-winx64目录下创建一个 my.ini目录文件

4.my.ini内容如下:

[client]

 default-character-set=utf8

 [mysqld]

 port=3306

 basedir  ="D:\Program Files (x86)\mysql-5.7.9-winx64/"

 datadir  ="D:\Program Files (x86)\mysql-5.7.9-winx64/data/"

 tmpdir   ="D:\Program Files (x86)\mysql-5.7.9-winx64/data/"

 #socket   ="D:\Program Files (x86)\mysql-5.7.9-winx64/data/mysql.sock"

 log-error="D:\Program Files (x86)\mysql-5.7.9-winx64/data/mysql_error.log"

 #server_id = 2

 #skip-locking

 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 (x86)\mysql-5.7.9-winx64/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

 join_buffer_size = 128M

 sort_buffer_size = 32M

 read_rnd_buffer_size = 32M

 max_allowed_packet = 32M

5.将mysql注册为windows系统服务

进入cd D:\Program Files (x86)\mysql-5.7.9-winx64\bin 目录下

执行:mysqld install MySQL --defaults-file="D:\Program Files (x86)\mysql-5.7.9-winx64\my.ini" 

6.初始化Date目录

mysqld  --initialize-insecure

7.启动mysql服务:

在命令行启动mysql命令为: net start mysql

--关闭mysql命令为:net stop mysql

--移除mysql服务:mysqld remove

8.修改root的密码为root

命令行执行:mysql –uroot

mysql>show databases;

mysql>use mysql;

mysql>set password for root@localhost = password('root');

mysql>exit;

9.用新密码登录OK
