mysql安装 8.0.25 zip

本文主要是介绍mysql安装 8.0.25 zip，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

好气啊，我用msi包安装了十几遍都没成功！！！！最终解决了 哎。。。心累

1.下载MySQL链接

https://dev.mysql.com/downloads/mysql/

2.解压zip 

        自己找个位置，解压完大致长这样（可别下载debug版本啊，哎。。。心累，我感觉把所有的坑踩了一遍）

4.初始化Mysql

创建文件(ACSI编码)  重点！！！！！！！ 见下图

先新建一个文件，一般都是新建一个txt嘛， 编辑下面这段配置。之后另存为  my.ini, 还得配置编码我跟你讲！！！！

下面这个配置信息  basedir    datadir 这个换成自己的 `D:\soft\mysql-8.0.25-winx64`

\Data 别动  注意：Data文件夹不要手动创建，让他自动生成

my.ini文件代码如下：别抄我的 自己看着改改 主要是路径，如果一会报错了，试试将这两个地方的单\ 都改为\\ ,例如： 

`basedir=D:\\soft\mysql-8.0.25-winx64

datadir=D:\\soft\mysql-8.0.25-winx64\\Data`

[mysqld]
port=3306
basedir=D:\soft\mysql-8.0.25-winx64
datadir=D:\soft\mysql-8.0.25-winx64\Data
max_connections=200
max_connect_errors=10
character-set-server=utf8mb4
default-storage-engine=INNODB
default_authentication_plugin=mysql_native_password
[mysql]
default-character-set=utf8mb4
[client]
port=3306
default-character-set=utf8mb4

文件另存为，改一下编码，保存！！！！！

5.以管理员身份打开命令行

你可能跟我一样直接在文件夹里来个 cmd 打开的，不得行！！！！！

 切换到自己的mysql安装目录bin下

6.执行命令

mysqld --initialize --console

7.记住临时密码{注意，要等他执行完命令后自动退出}

最后就是 初始化密码  ：  root@localhost: ZPv(aI(AU3<9

D:\software\mysql-8.0.25-winx64\bin>mysqld --initialize --console

8.安装mysql服务

执行：mysqld --install

9.启动Mysql服务

还是在bin下执行：

net start mysql

`D:\software\mysql-8.0.25-winx64\bin>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。
`启动成功

10.修改密码

执行：mysql -u root -p

再输入刚刚保存的临时密码

如图出现出现（mysql> ）字样代表成功

再执行(注意下面的语句是不是英文输入法的单引号）

ALTER USER 'root'@'localhost' IDENTIFIED BY 'admin';

密码就改成 admin了 

刷新权限，使新密码生效

flush privileges;

再次登录出现mysql即成功

最后附下my.ini 弄好之后的操作：

cd bin

D:\software\mysql-8.0.25-winx64\bin>mysqld --initialize --console
