进入终端后，我们先尝试ls命令

ls命令，是显示目录内的文件，类似CMD中的dir。和powershell中的ls类似。

如果没有nginx-1.6.0.sh这份文件，我们可以运行一下VIM把下面的文件保存为nginx-1.6.0.sh

然后，我们需要更改文件的运行权限

chmod +x nginx-1.6.0.sh

然后在运行nginx-1.6.0.sh文件

./nginx-1.6.0.sh

等待运行结束，可以看到这个界面

这个时候，我们再浏览一下IP，可以看到

则证明nginx安装成功。

接下来我们需要安装一下spawn-fcgi和fcgi，在shell界面下执行

yum -y install spawn-fcgi

yum -y install fcgi-devel

切换到网站运行目录

cd /alidata/www/default/

新建一份C文件

vim a.cpp

按下i进入编辑模式

#include "fcgi_stdio.h"
#include <stdlib.h>
#include <stdio.h>int main()
{while(FCGI_Accept() >= 0)     {printf("Content-type: text/*\r\n\r\n"); printf("欢迎来到由阿里云运行的C语言");}return 0;
}

按下ESC退出编辑模式，输入

:wq

保存及退出VIM

编译这个文件

g++ a.cpp -o index.aliC -lfcgi

等待完成后，我们就可以去编译我们的C语言了

接下来，把文件替换一下，因aliyun是经过优化的，我们需要他原来的那份默认配置编辑

\cp -rf /alidata/nginx/conf/nginx.conf.default /alidata/nginx/conf/nginx.conf

运行VIM编辑文件并定位到第65行

vim /alidata/nginx/conf/nginx.conf +65
