// 当访问当前域名80端口的时候，会去访问 root设置的目录下的网页
// 如果服务是在8000端口， 就可以通过上面的配置将请求在上面域名80端口的请求转发到 服务器上面的8000端口 
// 通过这种转发的机制可以配置多个服务，如果需要使用https 只需要将80端口改为443

　　}

　　location /proj2/ {
　　　　proxy_pass http://www.aaa.con:8087/proj2/;
　　}
 }

   这段配置的意思是访问www.aaa.com或者aaa.com的请求，会被nginx映射到http://www.aaa.con:8087/proj1/；
而访问www.bbb.com或者bbb.com的请求，
会被映射到http://www.aaa.con:8087/proj2/。多配置location /proj1/的原因是避免CSS/JS等在html中设置了
项目名路径的资源因为nginx的反向代理造成丢失工程名而无法访问到资源。

      这样，我们就能够在一台机器上发布针对若干个域名的WEB服务了。

修改 /etc/profile 文件，在文件末尾加上如下两行代码 
PATH=$PATH:/usr/local/MATLAB/R2013a/bin 
export PATH

export PATH=$PATH:/usr/local/nginx/sbin

最后执行命令 source /etc/profile 或执行点命令 ./profile 使其修改生效。
