--------------------

### 一、环境准备 ###

官网下载地址：[https://downloads.mysql.com/archives/community/][https_downloads.mysql.com_archives_community]

mysql-5.7.22-win32.zip：[https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.22-win32.zip][https_cdn.mysql.com_archives_mysql-5.7_mysql-5.7.22-win32.zip]

mysql-5.7.22-win64.zip：[https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.22-winx64.zip][https_downloads.mysql.com_archives_get_p_23_file_mysql-5.7.22-winx64.zip]

64位和32位安装步骤一致

### 二、配置文件 ###

这里解压到 D:\\MySQL 目录

my.ini 文件内容如下：

[mysqld]
    port=3306
    basedir=D:\MySQL\mysql-5.7.22-win32
    datadir=D:\MySQL\mysql-5.7.22-win32\data
    
    explicit_defaults_for_timestamp=true
    character-set-server=utf8
    default-storage-engine=INNODB
    sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
    ## sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
    
    max_connections=1000
    max_allowed_packet=8G
    tmp_table_size=16G
    max_heap_table_size=12G
    
    [mysql]
    default-character-set=utf8
    ## default-collation=utf8_general_ci

### 三、配置环境变量 ###

### 四、验证版本 ###

mysql -V

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxMjYyNTkzNDIx_size_16_color_FFFFFF_t_70 1][]

### 五、命令行安装 ###

右击我的电脑，选择 命令提示符（管理员）

mysqld --initialize

mysqld -install

> The service already exists!  
> The current server installed: D:\\MySQL\\mysql-5.7.22-win32\\bin\\mysqld MySQL

如果出现以上报错，使用管理员身份执行以下命令

sc query mysql  ::查看mysql服务
    sc delete mysql ::删除mysql服务
    mysqld -install ::安装mysql服务

net start mysql

### 六、重置密码 ###

在日志文件D:\\MySQL\\mysql-5.7.22-win32\\data\\AlEinstein.err 查看自动生成的密码，使用临时密码登录并修改密码

日志文件：配置的 /data 目录下的 .err后缀的 文件 user 指用户名或电脑名

mysql -uroot -p

set password for root@localhost=password('123456');

### 七、允许远程登录 ###

grant all privileges on *.* to root@'%' identified by '123456';
    flush privileges;

### 八、防火墙开启端口 ###
