现在有两个前端app-H5项目，共用了一个pc端后台接口，简单的方法是配两个端口访问不同的前端项目，但是客户服务器只有一个80端口开放，于是乎研究了下一个端口下nginx部署多个前端项目的方法，这个功能类似于tomcat，在tomcat下是可以放多个项目的，但是tomcat没有反向代理功能，所以淘汰了tomcat使用nginx会比较方便。

如上图在nginx服务器中有两个前端项目 一个在默认的html文件夹下的index.html，一个在gtmcApp文件夹下的index.html

编辑conf文件夹下的nginx.conf文件

    #        root   html;

    #    }
    #}

}

如上面配置，在80端口下配置两个location，一个是根目录，通过配置root来指定html文件夹（默认就是这个），一个是/gtmcApp目录，通过配置alias gtmcApp;来实现gmtcApp文件夹的识别，每个server只能有一个root 所以在根目录默认有root之后，可以通过alias来配置其他文件夹，其他两个location共用的同一个后台，通过/api/和/gtmcApp/api/来区分

如此，localhost访问的根目录进入一个前端项目 localhost/gtmcApp进入第二个前端项目便配置好了。
