mysql-5.7.16-winx64 安装

官方下载地址：http://dev.mysql.com/downloads/mysql/

我这里下载的是：MySQL Community Server 5.7.16（Windows (x86, 64-bit), ZIP Archive）

win7 系统安装到D盘根目录

1、将压缩包解压到D盘根目录

D:\mysql-5.7.16-winx64

2、修改D:\mysql-5.7.16-winx64\my-default.ini文件

 basedir = D:\mysql-5.7.16-winx64
 datadir = D:\mysql-5.7.16-winx64\data
 port = 3306
 server_id = 1
 tempdir = D:\mysql-5.7.16-winx64\temp


skip-grant-tables
skip-networking

完整配置如下：

# 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.

[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:\mysql-5.7.16-winx64
 datadir = D:\mysql-5.7.16-winx64\data
 port = 3306
 server_id = 1
 tempdir = D:\mysql-5.7.16-winx64\temp


# 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 

#修改mysql 配置文件跳过密码验证，密码修改完成后请将他们注释掉
skip-grant-tables
skip-networking

3、添加系统变量MYSQL_HOME,变量值为：D:\mysql-5.7.16-winx64

在系统变量path中添加%MYSQL_HOME%\bin;(记得加英文分号)

4、安装mysql 服务

以系统管理员身份打开cmd命令行，命令行中切换到D:\mysql-5.7.16-winx64\bin目录，输入：

mysqld --install

5、初始化mysql

还是在刚才的命令窗口，输入：

mysqld --initialize

输入命令后会创建data目录及相关文件

6、启动mysql服务

net start MySQL

7、修改root默认密码

用记事本打开D:\mysql-5.7.16-winx64\data\下后缀位.err 的文件。我这里是WIN-6.err。

查找password，这里v%eKW7DekFrt是随机生成的密码，用于下面登陆使用。

[Note] A temporary password is generated for root@localhost: v%eKW7DekFrt

8、执行mysql -uroot -pv%eKW7DekFrt登陆mysql

mysql -uroot -pv%eKW7DekFrt

9、输入命令修改密码

SET PASSWORD = PASSWORD('123456');

密码设置为123456，exit退出MySQL，然后就可以重新登陆了。

------------------------------------------------------------------------------------------------------------

在到第6步，启动MySQL服务时候遇到一个问题，服务无法启动，没有错误信息提示。。。

通过下面命令删除，重新安装了一下，然后启动服务ok。

mysqld --remove 删除mysql服务

mysqld --install 安装mysql服务

mysqld --initialize 一定要初始化

net start mysql 启动服务
