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。
本文操作环境：ubuntu 16.04系统、PHP7.1版、DELL G3电脑
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 ; a specific port; ; 'port' - to listen on a TCP socket to all addresses on a ; specific port; ; '/path/to/unix/socket' - to listen on a unix socket. ; Note: This value is mandatory. listen = 127.0.0.1:9000
