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

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)
