在 Windows 10 中安装 phpMyAdmin 4.8，基于 Composer 安装升级，以避免后续手动安装升级的麻烦

1、参考网址：https://docs.phpmyadmin.net/zh_CN/latest/setup.html#installing-using-composer

2、基于 Composer 安装，运行命令，如图1

4、使用安装程序生成配置文件：config.inc.php，打开浏览器并使用 /setup 后缀访问，网址：http://localhost/phpmyadmin-localhost/setup/ ，新建服务器，如图3

图3

5、点击 应用 按钮后，再点击 下载 按钮，以下载配置文件：config.inc.php，如图4、图5

图5

6、复制 config.inc.php 至 /phpmyadmin-localhost/config.inc.php，打开网址：http://localhost/phpmyadmin-localhost ，有警告信息：phpMyAdmin 高级功能尚未完全设置，部分功能未激活。查找原因。如图6

图6

7、按照提示：Create a database named ‘phpmyadmin’ and setup the phpMyAdmin configuration storage there.，点击 Create 链接，成功创建数据库：phpmyadmin，回到主页，警告信息已消失，如图7

8、打开网址：https://www.phpmyadmin.net/themes/ ，下载主题：Metro 2.8，复制至 /themes/，切换主题为：Metro，如图8、图9

9、注：主题的安装升级暂时没有法子基于 Composer ，只能够通过下载的方案实现，且基于 Composer 安装升级不能够升级至最新的版本：4.8.3，原因在于 Composer 库的版本更新有所延迟，需要等待。

10、当要增加新的服务器时，需要先删除 /phpmyadmin-localhost/config.inc.php，打开网址：http://localhost/phpmyadmin-localhost/setup/ ，新建服务器，如图10

图10

11、下载配置文件：config.inc.php，复制 config.inc.php 至 /phpmyadmin-localhost/config.inc.php，打开网址：http://localhost/phpmyadmin-localhost ，登录时，选择服务器已经存在2个，可以自行选择登录哪个服务器，如图11
