CentOS7配置Nginx+Spawn-fcgi+fcgi（新）

注：全局使用超级用户root进行配置

1.准备

nginx-1.12.2.tar.gz（来源：wget http://nginx.org/download/nginx-1.12.2.tar.gz）

spawn-fcgi-1.6.4.tar.gz（来源：wget http://download.lighttpd.net/spawn-fcgi/releases-1.6.x/spawn-fcgi-1.6.4.tar.gz）

fcgi-2.4.0.tar.gz（来源：wget http://down1.chinaunix.net/distfiles/fcgi-2.4.0.tar.gz）

tar -xzvf 压缩包　　#进行解压

2.安装Nginx

（1）执行：yum -y install pcre-devel　　#HTTP rewrite module requires the PCRE library

（2）执行：yum -y install zlib-devel　　#HTTP gzip module requires the zlib library

（3）执行：yum -y install openssl-devel　　#SSL modules require the OpenSSL library

（4）执行：./configure --with-http_ssl_module

运行结果：

Configuration summary
+ using system PCRE library
+ using system OpenSSL library
+ using system zlib library

nginx path prefix: "/usr/local/nginx"
nginx binary file: "/usr/local/nginx/sbin/nginx"
nginx modules path: "/usr/local/nginx/modules"
nginx configuration prefix: "/usr/local/nginx/conf"
nginx configuration file: "/usr/local/nginx/conf/nginx.conf"
nginx pid file: "/usr/local/nginx/logs/nginx.pid"
nginx error log file: "/usr/local/nginx/logs/error.log"
nginx http access log file: "/usr/local/nginx/logs/access.log"
nginx http client request body temporary files: "client_body_temp"
nginx http proxy temporary files: "proxy_temp"
nginx http fastcgi temporary files: "fastcgi_temp"
nginx http uwsgi temporary files: "uwsgi_temp"
nginx http scgi temporary files: "scgi_temp"

（5）执行：make && make install　　#编译及安装

（6）查看安装位置：whereis nginx

结果：

nginx: /usr/local/nginx

3.spawn-fcgi安装

（1）执行：./configure

（2）执行：make && make install

（3）查看版本：spawn-fcgi -v

 结果：

spawn-fcgi v1.6.4 - spawns FastCGI processes

4.fcgi库安装

（1）执行：./configure

（2）修改include/fcgio.h文件，加入#include <stdio.h>　　#防止出现编译错误：error: 'EOF' was not declared in this scope

（3）执行：make && make install

5.fcgi编程

（1）样例代码

#include <fcgi_stdio.h>

int main(int argc, char *argv[])
{
        while( FCGI_Accept() >=0 )
        {
                FCGI_printf("Content-Type: text/html\r\n\r\n");
                FCGI_printf("Hello world!");
        }

        return 0;
}

（2）编译：g++ -o test.fcgi test.cpp -L/usr/local/lib -lfcgi

（3）测试运行：./test.fcgi

如果出现类似错误：

./test.fcgi: error while loading shared libraries: libfcgi.so.0: cannot open shared object file: No such file or directory

 则进行如下处理：

将路径/usr/local/lib添加到文件/etc/ld.so.conf的末尾

文件打开命令可以使用：visudo　　#vi /etc/ld.so.conf　　//或者用vi命令

变更后，形如：

include ld.so.conf.d/*.conf
/usr/local/lib

 运行ldconfig命令马上生效

（参考：https://www.cnblogs.com/chris-cp/p/3591306.html）

 5.启动fcgi应用程序

（1）将fcgi程序统一存储至一个目录，例如：cp test.fcgi /usr/local/nginx/fcgi-bin

（2）启动程序：spawn-fcgi -a 127.0.0.1 -p 9001 -F 10 -f /usr/local/nginx/fcgi-bin/test.fcgi

 6.启动nginx

（1）打开配置文件：vi conf/nginx.conf

（2）将原配置：

        #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;
        #}

　　改为：

        location = /test.fcgi {
        #    root           html;
            fastcgi_pass   127.0.0.1:9001;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            include        fastcgi_params;
        }

（3）启动：./nginx　　#./nginx -s reload //重新加载

7.Http访问

 8.服务器外部访问

打开服务器外部访问端口，重启防火墙：

firewall-cmd --add-port=80/tcp --permanent
firewall-cmd --reload
