今天尝试搭建了个 CentOS+NGINX+Spawn-fcgi+CPP 的开发环境。

测试环境

  • CentOS
  • Nginx

安装 GCC、GCC-C++ 等工具

1
yum install gcc gcc-c++ autoconf automake

安装 Spawn-fcgi

1
yum install fcgi-devel spawn-fcgi

编写 FCGI 程序并编译

#include <stdlib.h>
#include <fcgi_stdio.h>
 
int main(int argc, char **argv) {
    int count = 0;
    while(FCGI_Accept() >= 0)
        printf("Content-type: text/html\n\n"
               "<html><head><title>FastCGI Hello!</title></head>\n"
               "<body><h1>FastCGI Hello!</h1>\n"
               "Request number %d running on host <i>%s</i></body></html>\n",
               ++count, getenv("SERVER_NAME"));
    return 0;
}

保存为 hello.cpp，然后编译：

1
gcc -o hello.cgi hello.cpp -lfcgi

Spawn-fcgi 执行 FCGI 程序

1
2
[root@localhost ~]# spawn-fcgi -p 3000 -f /data/web/fcgi/hello.cgi 
spawn-fcgi: child spawned successfully: PID: 2956

监听 3000 端口，执行刚刚编译的 FGCI 程序。可以看到执行完进程 ID 是 2956。如果要结束进程，用 kill 命令即可。

配置 Nginx

1
vim /etc/nginx/conf.d/default.conf

修改配置为：

server {
    listen       80;
    server_name  localhost;
 
    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;
 
    #location / {
    #    root   /usr/share/nginx/html;
    #    index  index.html index.htm;
    #}
 
    #Broly: FCGI Config
    location / {
        root   /data/web/fcgi;
        index  index.cgi;
    }
	
    location ~ \.cgi$ {
        fastcgi_pass   127.0.0.1:3000;
        fastcgi_index  index.cgi;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
 
    #error_page  404              /404.html;
 
    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
 
    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}
 
    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}
 
    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

保存并退出。然后重启 Nginx：

1
systemctl restart nginx.service
