nginx+fastcgi+c/cpp

参考：http://github.tiankonguse.com/blog/2015/01/19/cgi-nginx-three/

跟着做了一遍，然后根据记忆写的，不清楚有没错漏步骤，希望多多评论多多交流。。。

搭建环境

注意发现碰钉可以看看相应程序内的README

安装：nginx、spawn-fcgi、fastcgi、fcgiwrap

nginx

sudo apt-get install nginx-full

fastcgi

安装fastcgi的时候报EOF错误可以在include/fcgio.h中包含头文件cstdio

wget http://www.fastcgi.com/dist/fcgi.tar.gz
tar -zxvf fcgi.tar.gz
./configure
make
sudo make install

spawn-fcgi

git clone https://github.com/lighttpd/spawn-fcgi.git
sudo apt-get install autoconf
autoreconf -i
./autogen.sh
./configure
make
sudo make install

fcgiwrap

git clone https://github.com/gnosek/fcgiwrap.git
autoreconf -i
./configure
make
sudo make install

配置环境

配置nginx

vim /etc/nginx/sites-enabled/default

整个文件改成这样

server {

    listen 80 ;
    server_name nextbin.com;

    location / {
        root /home/zebin/nginx/htdoc/;
        index index.html index.htm;
        try_files $uri $uri/ =404;
    }

    location ~ ^/cgi-bin/.*$ {
        #cgi path: /home/zebin/nginx/cgi-bin/
        root /home/zebin/nginx/;
        fastcgi_pass 127.0.0.1:9000;
        #configure path: /etc/nginx/fastcgi.conf
        #include fastcgi.conf;
        include fastcgi_params;
    } 

}

配置hosts

vim /etc/hosts

追加

127.0.0.1 nextbin.com

配置库文件链接

sudo ln -s /usr/local/lib/libfcgi.so.0.0.0 /usr/local/lib/libfcgi.so.0
sudo ln -s /usr/local/lib/libfcgi.so.0.0.0 /usr/lib/libfcgi.so.0
sudo mkdir /usr/lib64
sudo ln -s /usr/local/lib/libfcgi.so.0.0.0 /usr/lib64/libfcgi.so.0

测试cgi

编写cgi程序编译后将可执行程序放在相应目录（如/home/zebin/nginx/cgi-bin/demo）

#include "fcgi_stdio.h"
#include <stdlib.h>

int main(int argc, char* argv[]){
    int count = 0;
    while (FCGI_Accept() >= 0){
        printf("Content-type: text/html
"
        "
"
        "<title>FastCGI Hello!</title>"
        "<h1>FastCGI Hello!</h1>"
        "Request number %d running on host <i>%s</i>
",
        ++count, getenv("SERVER_NAME"));
    }
    return 0;
}

编译：g++ demo.cpp -lfcgi -o demo

加载fcgi-application

spawn-fcgi -p 9000 -C 10  -f  /usr/local/sbin/fcgiwrap

浏览器访问 nextbin.com/cgi-bin/demo 都成功

=========小结=========

一些用得上的命令

ps -aux | grep cgi
nginx -t
ln --help

折腾了一天终于搭建好了。之前只试过LNMP。

1. 还没用上数据库，有待补充

2. 对spawn-fcgi、fcgiwrap、fastcgi的关系不清晰，有待理解

3. 对信息传输交互没接触，有待构建
