php 9000端口没有启动怎么办

PHP 9000端口没有启动的解决办法：1、找到“PHP5/fpm/pool.d/www.conf”；2、将listen改为“127.0.0.1:9000”；3、将Nginx改回用端口监听的方式；4、重启Nginx和PHP-fpm即可。

PHP 9000端口没有启动怎么办?PHP-fpm启动以后，没有出现9000端口?

最近在复现一个PHP扩展的后门，需要搭建Nginx+PHP环境，Nginx我是用源码裸装的，不带任何第三方模块。

PHP-cli和PHP-fpm 则是通过ubuntu的标准apt-get命令安装的。

随后需要修改Nginx的Nginx.conf文件让其支持PHP脚本解析。

经查询网上的配置有两种，一种是

支持127.0.0.1：9000

location ~ \.PHP$ {
    root           html;
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.PHP;
    fastcgi_param  SCRIPT_FILENAME   /usr/local/Nginx/html/$fastcgi_script_name;
    include        fastcgi_params;
}

另一种是使用sock文件

location ~ .PHP$ {
        root           /usr/share/Nginx/html;
        fastcgi_pass   unix:/var/run/PHP-fpm/PHP5-fpm.sock;
        fastcgi_index  index.PHP;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

刚开始使用第一种9000端口的方式进行配置，PHP解析不了，后经过查询PHP-fpm日志，发现有sock

[17-Sep-2019 00:23:02] NOTICE: fpm is running, pid 5617
[17-Sep-2019 00:23:02] NOTICE: ready to handle connections
[17-Sep-2019 00:23:02] NOTICE: systemd monitor interval set to 10000ms
[17-Sep-2019 00:31:28] ERROR: An another FPM instance seems to already listen on /var/run/PHP5-fpm.sock
[17-Sep-2019 00:31:28] ERROR: FPM initialization Failed
[17-Sep-2019 00:37:34] NOTICE: configuration file /etc/PHP5/fpm/PHP-fpm.conf test is successful

随后在Nginx配置文件中改用第二种sock文件交互的模式，发现还是页面解析不了。

最后找到/etc/PHP5/fpm/pool.d/www.conf 配置文件，将listen改为127.0.0.1:9000

又将Nginx改回用端口监听的方式，重启Nginx和PHP-fpm以后，终于可以解析PHP脚本了。。

Nginx.conf配置文件

 server {
        listen       80;
        server_name  localhost;
        root   html;
        index  index.PHP;
        location ~\.PHP$ {
            fastcgi_pass  127.0.0.1:9000;
            fastcgi_index index.PHP;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
        }

/etc/PHP5/fpm/pool.d/www.conf文件修改的地方：

; The address on which to accept FastCGI requests.
; Valid Syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific address on

;                            specific port;
;   '/path/to/unix/socket' - to listen on a unix socket.

listen = 127.0.0.1:9000
