一、下载MySQL
MySQL官网:https://www.mysql.com/cn/
mysql-8.0.31-winx64下载地址:https://dev.mysql.com/downloads/mysql/
2、下载结束后,解压到指定目录,笔者存放在D盘 ,为求简单,设置目录如下:
D:\mysql-8.0.31-winx64
3、新建my.ini文件,并粘贴如下内容,可依实际修改。
注意:修改:basedir、datadir、属性;
[mysqld]
port=3306
basedir=D:\mysql-8.0.31-winx64
datadir=D:\mysql-8.0.31-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
4、安装与配置mysql ,以管理员身份打开cmd
注意:打开cmd 窗口要跳转到:d:\mysql-8.0.31-winx64 目录下:
跳转命令:C:\Windows\system32>cd /d d:\mysql-8.0.31-winx64
cd 后面要加 “/d” ,后面就是你的目录“d:\mysql-8.0.31-winx64”
d:\mysql-8.0.31-winx64>cd bin #管理员身份打开cmd,进入mysql bin目录
d:\mysql-8.0.31-winx64\bin>mysqld --install #运行安装命令
#笔者前期运行过,首次运行该命令结果为 Service successfully installed.
The service already exists!
The current server installed: D:\mysql-8.0.31-winx64\bin\mysqld MySQL
d:\mysql-8.0.31-winx64\bin>mysqld --initialize
#初始化 Data目录下会生成计算名命名的 .err文件,初始密码位于***@localhost:后
d:\mysql-8.0.31-winx64\bin>net start mysql #启动mysql服务
MySQL 服务正在启动 .
MySQL 服务已经启动成功。
d:\mysql-8.0.31-winx64\bin>mysql -u root -p #登录
