**1、解压**

**2、初始化脚本 my.ini，放到 mysql 的解压目录，与 bin 目录平级**

# 设置3306端口
    port=3306
    # 设置mysql的安装目录
    basedir=E:\install\mysql8\product
    # 设置mysql数据库的数据的存放目录
    #datadir=E:\install\mysql8\data
    # 允许最大连接数
    max_connections=200
    # 允许连接失败的次数。
    max_connect_errors=10
    # 服务端使用的字符集默认为utf8mb4
    character-set-server=utf8mb4
    # 创建新表时将使用的默认存储引擎
    default-storage-engine=INNODB
    # 默认使用“mysql_native_password”插件认证
    #mysql_native_password
    default_authentication_plugin=mysql_native_password
    [mysql]
    # 设置mysql客户端默认字符集
    default-character-set=utf8mb4
    [client]
    # 设置mysql客户端连接服务端时默认使用的端口
    port=3306
    default-character-set=utf8mb4

**3、管理员方式启动 CMD**

**4、在 mysql 安装目录的 bin 目录，执行安装命令**

mysqld --initialize --console

本地报错

我从脚本之家下了这个 dll 文件  
[http://xz6.jb51.net:81/dll/2019/vcruntime140\_1\_jb51.rar][http_xz6.jb51.net_81_dll_2019_vcruntime140_1_jb51.rar]  
将 vcruntime140\_1.dll 文件放到 C:\\Windows\\System32 目录下

继续执行安装指令

mysqld --initialize --console

**5、安装成功，生成 root 用户的临时密码**

![format_png 1][]

**6、安装服务**

mysqld --install

![format_png 2][]  
已存在需要删除，sc delete mysql

**7、启动服务**

net start mysql

![format_png 3][]

**8、连接 mysql，修改密码**

mysql -u root -p

输入临时密码

![format_png 4][]

**9、修改 localhost 的 root 密码**

ALTER USER 'root'@'localhost' IDENTIFIED BY 'constxiong@123';

![format_png 5][]

**10、用 navicate 连接，操作**

![format_png 6][]
