在ubuntu下为nginx配置支持cgi脚本的方案

在nginx下支持cgi脚本于支持node类似的，只要在nginx直接做个转发，转发到对应的cgi套接字就好。

使用Fcgiwrap

Fcgiqwrap是另外一个CGI封装库，跟Simple CGI类似。

安装fcgiwrap

apt-get install fcgiwrap

安装以后fcgiwrap默认已经启动，对应的套接字是 /var/run/fcgiwrap.socket 。如果没有启动，使用 /etc/init.d/fcgiwrap 手动启动。

配置nginx的vhost文件

在要支持cgi脚本的路径下，添加对应的server配置。比如所有的cgi都在cgi-bin路径下：

server {
[...]
  location /cgi-bin/ {
   # Disable gzip (it makes scripts feel slower since they have to complete
   # before getting gzipped)
   gzip off;
   # Set the root to /usr/lib (inside this location this means that we are
   # giving access to the files under /usr/lib/cgi-bin)
   root /var/www/www.example.com;
   # Fastcgi socket
   fastcgi_pass unix:/var/run/fcgiwrap.socket;
   # Fastcgi parameters, include the standard ones
   include /etc/nginx/fastcgi_params;
   # Adjust non standard parameters (SCRIPT_FILENAME)
   fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  }
[...]
}

重新加载nginx：

nginx -s reload

测试

在cgi-bin下创建hello-world.cgi

#!/usr/bin/perl -w
   # Tell perl to send a html header.
   # So your browser gets the output
   # rather then (command line
   # on the server.)
print "Content-type: text/html\n\n";
   # print your basic html tags.
   # and the content of them.
print "\n";
print "
Hello world
\n";

设置执行权限

chmod 755 /var/www/www.example.com/cgi-bin/hello_world.cgi

在浏览器打开对应脚本，即可看到已经配置成功！ http://www.example.com/cgi-bin/hello_world.cgi
