window下MySQL5.7.zip服务配置

官网下载了压缩包版本的mysql-5.7.13-winx64.zip,解压。

再解压目录下新建一个my.ini文件，内容如下：

# 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.[mysql]# 设置mysql客户端默认字符集default-character-set=utf8[mysqld]# 忽略登录检查(<span style="font-family: Arial, Helvetica, sans-serif;">忽略</span><span style="font-family: Arial, Helvetica, sans-serif;">登陆检查)</span>skip_grant_tables# Remove leading # and set to the amount of RAM for the most important data# cache in MySQL.

skip_grant_tables 忽略登录检查；mysql5.7增加了安全性，初始密码不再为空。

以管理员身份运行cmd, 打开到文件解压的目录中的bin下运行下面的指令创建并且启动服务(可以在环境变量设置为全局指令)：

D:\software\mysql\mysql-5.7.13-winx64\bin>mysqld --initializeD:\software\mysql\mysql-5.7.13-winx64\bin>mysqld --installService successfully installed.D:\software\mysql\mysql-5.7.13-winx64\bin> net start mysqlMySQL 服务正在启动 .MySQL 服务已经启动成功。D:\software\mysql\mysql-5.7.13-winx64\bin>mysql -uroot -pEnter password:Welcome to the MySQL monitor.

mysqld --initialize 初始化目录（data目录），如果执行命令失败，需先删除data目录后再执行；

mysqld -install 初始化mysql服务；

net start mysql 启动服务；

net stop mysql 停止服务。

修改密码：

</pre><pre name="code" class="plain">mysql> use mysql;Database changedmysql> update user set authentication_string=password('123456') where user='root';Query OK, 0 rows affected, 1 warning (0.00 sec)Rows matched: 1  Changed: 0  Warnings: 1mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)

mysql5.7的user中没有password字段，保存密码的字段变成authentication_string

关闭mysql服务，删掉my.ini中的skip_grant_tables；

重新启动服务，输入密码就可以登陆。

出现下面这个：

You must reset your password using ALTER USER statement before executing this statement.

解决:

step 1: SET PASSWORD = PASSWORD('root'); 
step 2: ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
step 3: flush privileges;
