安装步骤

下载8.0.25（压缩版）

https://cdn.mysql.com/archives/mysql-8.0/mysql-8.0.25-winx64.zip

解压并设置

第一步：解压mysql-8.0.25-winx64.zip 至 C:\WindowsApplicaions\mysql-8.0.25-winx64

第二步：配置环境变量 环境-> Path -> 环境变量

第三步：编辑my.ini

[mysql]
default-character-set=utf8

[mysqld]
port=3306
basedir=C:\WindowsApplicaions\mysql-8.0.25-winx64
datadir=C:\WindowsApplicaions\mysql-8.0.25-winx64\data
character-set-server=utf8
default-storage-engine=INNODB
skip_grant_tables

my.ini 存放路径（非常重要！）：C:\WindowsApplicaions\mysql-8.0.25-winx64\bin

第四步：初始化

C:\WindowsApplicaions\mysql-8.0.25-winx64\bin>mysqld --initialize --user=mysql --console
2023-03-22T06:45:22.360457Z 0 [System] [MY-013169] [Server] C:\WindowsApplicaions\mysql-8.0.25-winx64\bin\mysqld.exe (mysqld 8.0.25) initializing of server in progress as process 9992

2023-03-22T06:45:24.052125Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: TiBfhr5UkE%(

产生的临时密码：TiBfhr5UkE%(

第五步：安装mysql

mysqld --install

第六步：start mysql

net start mysql

第七步：登录

C:\WindowsApplicaions\mysql-8.0.25-winx64\bin>mysql -u root -p
Enter password: ************
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 9

输入临时密码后，即可成功登录。

删除MySQL服务

查看MySQL服务

正常运行后，查看service会看到MySQL服务

C:\WindowsApplicaions\mysql-8.0.25-winx64\bin>sc query mysql

SERVICE_NAME: mysql
        TYPE               : 10  WIN32_OWN_PROCESS
        STATE              : 4  RUNNING
                                (STOPPABLE, PAUSABLE, ACCEPTS_SHUTDOWN)
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0

通过命令可以看到服务详细信息

查看端口3306

C:\WindowsApplicaions\mysql-8.0.25-winx64\bin>netstat -ano | findstr "3306"
  TCP    0.0.0.0:3306           0.0.0.0:0              LISTENING       24164
  TCP    0.0.0.0:33060          0.0.0.0:0              LISTENING       24164
  TCP    [::]:3306              [::]:0                 LISTENING       24164
  TCP    [::]:33060             [::]:0                 LISTENING       24164
  TCP    [::1]:64861            [::1]:3306             TIME_WAIT       0

MySQL端口默认设置为3306，可通过命令检测

删除服务

C:\WindowsApplicaions\mysql-8.0.25-winx64\bin>sc delete mysql
[SC] DeleteService SUCCESS

成功删除MySQL服务后，service列表会删除MySQL服务。

修改密码

MySQL进入后，执行use mysql;会报错

mysql> use mysql;

C:\WindowsApplicaions\mysql-8.0.25-winx64\bin>mysql -u root -p
