windows安装Mysql解压版

一、下载mysql-8.0.36-winx64.zip

官网：https://dev.mysql.com/downloads/

二、解压

三、配置

3.1. 添加环境变量：新建MYSQL_HOME

MYSQL_HOME

%MYSQL_HOME%\bin

3.2.如何验证是否添加成功：必须以管理员身份启动

如果提示Can't connect to MySQL server on 'localhost'则证明添加成功；

如果提示mysql不是内部或外部命令，也不是可运行的程序或批处理文件则表示添加添加失败，请重新检查步骤并重试。

mysql

3.3. 初始化MySQL：必须以管理员身份启动

以管理员身份，运行命令行窗口：

mysqld --initialize-insecure

如果没有出现报错信息，则证明data目录初始化没有问题，此时再查看MySQL目录下已经有data目录生成。

3.4. 注册MySQL服务：必须以管理员身份启动

mysqld -install

计算机上已经安装好了MySQL服务了

3.5. 启动MySQL服务

net start mysql  // 启动mysql服务
    
net stop mysql  // 停止mysql服务

3.6. 修改默认账户密码

在黑框里敲入mysqladmin -u root password 123456，这里的123456就是指默认管理员(即root账户)的密码。

mysqladmin -u root password 123456

四、登录MySQL

输入mysql -uroot -p1234，回车，出现下图且左下角为mysql>，则登录成功。

mysql -uroot -p123456

六、退出mysql：

exit
quit

七、登陆参数：

mysql -u用户名 -p密码 -h要连接的mysql服务器的ip地址(默认127.0.0.1) -P端口号(默认3306)

八、卸载MySQL

点击开始菜单，输入cmd，选择 “命令提示符”，选择右侧的 “以管理员身份运行”。

net stop mysql

mysqld -remove mysql

删除MySQL目录及相关的环境变量

九、MySQL卸载完成

十、my-default.ini
