1.  下载MySQL软件
2.  Windows平台下安装与配置MySQL
3.  Windows平台下ZIP版配置MySQL

**下载MySQL**

**Windows平台下载MySQL**

**(****1****)****进入MySQL的官网：https****://www.mysql.com/。****点击DOWNLOADS导航栏****，****再****点击Community（社区版****），****切换到社区版的下载页面，最后点击MySQL** **Community** **Server下边的DOWNLOAD按钮即可进入MySQL数据库****下载页面。**

**(****2****)****进入MySQL数据库的下载界面后，首先在“Select** **Operating** **System”下拉菜单中选择“Microsoft** **Windows”平台，然后进入MySQL下载页面****。**

**Linux平台下载MySQL**

**Linux操作系统的版本有很多种，如Red** **Hat Enterprise、Ubnutu、Debian、CentOS等，我们需要针对自己电脑选择适合的操作平台，然后再选择是下载32位的还是64位的文件。**

**下面以64位的CentOS7系统进行演示，由于CentOS系统是来自于Red Hat Enterprise** **Linux依照开放源代码规定释出的源代码编译而成的，所以下载时可以按照Red** **Hat平台进行选择版本的下载****。**

**需要注意的是，CentOS7系统不能只下载服务器端和客户端软件，还要下载一些依赖包，所以在此直接下载“RPM** **Bundle”压缩包。最后使用xftp或其他工具，将下载的压缩包上传到Linux服务器中的“download”目录中****。**

**安装与配置MySQL**

**安装MySQL**

**双击安装程序mysql-installer-community-8.0.12.0.msi，此时会弹出MySQL许可协议界面。单击选中复选框“I accept the license** **terms”后，点击“Next”按钮，进入安装类型选择界面****。**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpNjAzMDYwOTcx_size_16_color_FFFFFF_t_70 5][]

**选择自定义安装类型“Custom”（****此类型可以根据用户自己的需求选择安装需要的产品****），****然后单击“Next”按钮****。**

**配置MySQL**

**直接点击“Next”按钮，直接进入参数配置页面中的“Type** **and** **NetWorking”界面****。**

**进入“Type** **and** **Networking”界面后****，** **我们要选择的是“Standalone** **MySQL Server / Classic MySQL** **Replication”选项，然后点击“Next”按钮服务器配置类型“Config** **Type”选择“Development** **machine”，****不同的选择将决定系统为MySQL服务器实例分配资源的大小****，“Development** **machine”占用的内存是最少的；连接方式保持默认的TCP****/IP，端口号也保持默认的3306即可；点击“Next”按钮。**

**zip版MySQL的安装**

减压配置MySQL

**将下载的zip版安装文件解压到你想放到的磁盘处，例如****(E:\\mysql-8.0.12-winx64)。在mysql-8.0.12-winx64文件夹下找到my.ini，进行配置。如果没有.ini结尾的文件那么就新增。注意basedir和datadir是我自己的路径位置，根据自己的定夺。记得新增一个文件data文件夹**

**my.ini文件内容**

**\[****mysqld****\]**

**\# 设置3306端口**

**port=3306**

**\#** **设置mysql的安装目录**

**basedir****=E:\\\\mysql-8.0.12-winx64**

**\#** **设置mysql数据库的数据的存放目录**

**datadir****=E:\\\\mysql-8.0.12-winx64\\\\Data**

**\#** **允许最大连接数**

**max\_connections****=200**

**\#** **允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统**

**max\_connect\_errors****=10**

**\# 服务端使用的字符集默认为UTF8**

**character-set-server=utf8**

**\#** **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**

**default\_authentication\_plugin****=****mysql\_native\_password**

**\[****mysql****\]**

**\#** **设置mysql客户端默认字符集**

**default-character-set=utf8**

**\[client\]**

**\#** **设置mysql客户端连接服务端时默认使用的端口**

**port=3306**

**default-character-set=utf8**

•cmd打开命令窗口，初始化mysql，初始化语句：

mysqld --defaults-file=E:\\mysql-8.0.12-winx64\\my.ini --initialize –console

执行该语句后会出下日志内容，找到root@localhost，冒号后面的为mysql的初始密码，一定要先记住，下面用来登录修改密码。

•安装MySQL当前服务，

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpNjAzMDYwOTcx_size_16_color_FFFFFF_t_70 16][]

• 接着启动服务我们来修改密码，执行mysql -u root -p登录mysql，回车后输入我们记下来的初始密码，回车后进入mysql命令，输入修改密码命令ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql\_native\_password BY 'root'; root是你自己定义的密码。至此mysql免安装版的配置已完成。

•查看默认安装的数据库。执行如下命令：

show databases;
