### 进入MySQL官方下载通道 ###

### 选择合适的文件压缩包进行下载 ###

### 解压缩到自己的文件目录之下，并创建一个my.ini文件和data文件夹 ###

### ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM4MjM0MDE1_size_16_color_FFFFFF_t_70 3][] ###

### my.ini文件中写入如下配置信息 ###

[mysql]
    # 设置mysql客户端默认字符集
    default-character-set=utf8
    [mysqld]
    # 设置3306端口
    port = 3306
    # 设置mysql的安装目录
    basedir=C:\DataBase\mysql
    # 设置mysql数据库的数据的存放目录
    datadir=C:\DataBase\mysql\data
    # 允许最大连接数
    max_connections=20
    # 服务端使用的字符集默认为8比特编码的latin1字符集
    character-set-server=utf8
    # 创建新表时将使用的默认存储引擎
    default-storage-engine=INNODB
    
    wait_timeout=31536000
    interactive_timeout=31536000

***根据自己的文件路径对应修改mysql的安装目录和数据存放目录***

### 使用管理员权限打开cmd命令行 ###

### 进入MySQL文件的加压路径中的bin目录下 ###

C:\Windows\system32>cd C:\DataBase\mysql\bin
    
    C:\DataBase\mysql\bin>

### 输入初始化命令，等待计算机完成初始化 ###

C:\DataBase\mysql\bin>mysqld --initialize --console
    2019-04-30T09:09:37.144941Z 0 [Warning] option 'wait_timeout': unsigned value 31536000 adjusted to 2147483

    C:\DataBase\mysql\bin>

### 输入安装mysql的命令，完成安装 ###

C:\DataBase\mysql\bin>mysqld -install
    Service successfully installed.
    
    C:\DataBase\mysql\bin>

### 启动MySQL服务 ###

C:\DataBase\mysql\bin>net start mysql
    MySQL 服务正在启动 .
    MySQL 服务已经启动成功。
    
    
    C:\DataBase\mysql\bin>

### 现在，MySQL已经安装完成并启动，可以进行登录操作 ###

首次登录的密码是初始化时随机生成的密码，本次安装中生成的是 fgHs(n37-elf

C:\DataBase\mysql\bin>mysql -hlocalhost -uroot -p
    Enter password: ************

    mysql>

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

笔者安装过程中，由于使用了之前的my.ini配置文件，在配置文件中启用了二进制日志，导致初始化失败

C:\DataBase\mysql\bin>mysqld --initialize --console
    2019-04-30T09:07:33.533588Z 0 [Warning] option 'wait_timeout': unsigned value 31536000 adjusted to 2147483
    2019-04-30T09:07:33.537527Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
    2019-04-30T09:07:33.656415Z 0 [ERROR] You have enabled the binary log, but you haven't provided the mandatory server-id. Please refer to the proper server start-up parameters documentation
    2019-04-30T09:07:33.657652Z 0 [ERROR] Aborting

解决的方法很简单，只需要把my.ini文件中有关启用二进制日志的配置信息注释或者删除就可以了。

在具体的初始化和安装过程中，可能会出现各种形式的问题，但是一定会有相应的报错信息，根据报错信息是很容易找到原因并解决的。
