winx64 MySQL 5.7绿色版安装步骤

win安装绿色版 MySQL 5.7

一、下载安装服务

1.1. 下载解压

我的解压路径为:
D:\Env\MySQL\mysql-5.7.24-winx64

1.2. 配置环境变量

  • 变量名:MYSQL_HOME
  • 变量值:D:\Env\MySQL\mysql-5.7.24-winx64
  • path里添加:%MYSQL_HOME%\bin

1.3. 新建my.ini文件

[mysql]
default-character-set=utf8
[mysqld]
basedir=D:\Env\MySQL\mysql-5.7.24-winx64
datadir=D:\DataBase\MySQLData
port=3306
max_connections=200
character-set-server=utf8
default-storage-engine=INNODB
skip-grant-tables 

1.4. 安装服务命令

管理员打开CMD:

# 初始化
mysqld  --initialize

# 安装卸载服务
mysqld -install
mysqld -remove

# 启动停止mysql
net start mysql
net stop mysql

二、登陆创建密码

2.1. 登陆mysql

>mysql -uroot -p    #无密码
mysql> update mysql.user set authentication_string=password('123456') where user='root';    # 修改密码
mysql> flush privileges;    ##刷新权限
mysql> \q

2.2. 注释掉my.ini免密检查

[mysql]
default-character-set=utf8
[mysqld]
basedir=D:\Env\MySQL\mysql-5.7.24-winx64
datadir=D:\DataBase\MySQLData
port=3306
max_connections=200
character-set-server=utf8
default-storage-engine=INNODB
#skip-grant-tables

2.3. 重新登陆【完成安装】

mysql> alter user user() identified by "123456";

三、配置无密码登陆

[client] 
port = 3306  
default-character-set=utf8
host=127.0.0.1
user=root
password=123456

四、忘记密码修改

4.1. 关闭mysql密码检查

net stop mysql
mysqld --skip-grant-tables

4.2.多开一个cmd窗口,登陆mysq

4.3.修改密码重启电脑

mysql> update mysql.user set authentication_string=password('123456') where user='root';
mysql> flush privileges;
mysql> \q

4.4.登陆测试

>mysql -uroot -p

4.5.解决错误

mysql> alter user user() identified by "123456";

五、错误问题

5.1. msvcr120.dll丢失

安装Visual C++ Redistributable Packages

安装完成后重新执行上述步骤

5.2. ERROR 1820 (HY000)

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
声明密码

mysql> alter user user() identified by "123456";

六、版本差异

6.1.改密码

新版:

update mysql.user set authentication_string=password('123456') where user='root';

老版:

update user set password=password('新密码') where user='root'
