【Nginx】第一个程序Hello World

要注意，先关闭Nginx再添加第三方的模块，负责会编译不进去，我被这个地方坑了好久。
 
关闭命令：/usr/local/nginx/sbin/nginx -s quit
然后才是：
./configure --prefix=/usr/local/nginx --add-module=/root/coding/nginxcode
 make
sudo make install
最后启动Nginx：/usr/local/nginx/sbin/nginx
 
测试结果：
 
centos虚拟机下：
 
 
windows下：
附件：
location:
location /test {
    mytest;
}
