进入终端后，我们先尝试ls命令
ls
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

cd $DIR
bash
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
轻轻按下ctrl+v，进入编辑模式
按j选中我们要修改代码的注释
然后再按D删除注释
选到第65行，按i进入编辑模式把php改为aliC
同时，找到第66,68,69,70行可以删除，不删也没关系。
按下ESC然后输入:wq保存及退出
:wq
最后重启nginx
nginx -s reload
或者
killall nginx
nginx
最后，运行一下
spawn-fcgi -f /alidata/www/default/index.aliC -p 9000
看到如下提示证明成功了
接下来运行浏览器，打开http://localhost/index.aliC，或者执行
curl http://localhost/index.aliC
或者
curl http://127.0.0.1/index.aliC
即可看到如下结果
遇到的问题及解决方案
曾经遇到spawn-fcgi返回child exited with: 0的问题，经过搜索，解决方案很少，几乎找不到。
经过排查，发现是C的源码问题。需要加上
while(FCGI_Accept() >= 0)
