MySQL5.7绿色版安装

1. 下载MySQL 5.7，地址：http://dev.mysql.com/downloads/mysql/ （选择32位或者64位版本需根据自身PC情况）

2. 下载后解压，比如我的目录结构是：

3. 配置Path路径：系统属性 => 高级 => 高级 => 系统变量 => path后添加 F:\CSoft\MySQL-5.7\bin

4. 修改my-default.ini，此文件是初始化信息：

# For advice on how to change settings please see

# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the

[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 = F:\CSoft\MySQL-5.7
datadir = F:\CSoft\MySQL-5.7\data
port = 3306
# server_id = .....

# 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 = 2M
# read_rnd_buffer_size = 2M 

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
# !o>UZ!e(h6(m  初始化的密码

5. 系统管理员模式运行cmd 输入如下命令

C:\Users\LCF>F:          //切换到F目录
F:\>cd CSoft\MySQL-5.7\bin   //进入bin目录
F:\CSoft\MySQL-5.7\bin>mysqld --install   //安装MYSQL服务
Service successfully installed.  //提示服务安装成功
The current server installed: F:\CSoft\MySQL-5.7\bin\mysqld MySQL

F:\CSoft\MySQL-5.7\bin>mysqld --initialize --console  //根据配置文件初始化，此时会有一大堆消息，
(注意最后的消息:
2016-07-13T14:21:39.268917Z 1 [Note] A temporary password is generated for root@
localhost: !o>UZ!e(h6(m  )
后面这个是密码待会儿登录使用的。

F:\CSoft\MySQL-5.7\bin>net start mysql  //启动mysql服务
MySQL 服务正在启动 .
MySQL 服务已经启动成功。

F:\CSoft\MySQL-5.7\bin>mysql -uroot -p  //登录mysql
Enter password: ************   //密码就是输入的密码

mysql> set password=password('123456');     //修改密码
Query OK, 0 rows affected, 1 warning (0.00 sec)

目前为止成功安装。
