BUG:upstream timed out (10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected

更换Apache扑向Nginx，刚搭建完WNMP，nginx能访问php页面 但是访问现有开发项目报错

1 [error] 4112#3724: *9 upstream timed out (10060: A connection attempt failed because the connected party did not properly respond
2 after a period of time, or established connection failed because connected host has failed to respond) while reading response header
3 from upstream, client: 127.0.0.1, server: localhost, request: "GET /right/backend/web/index.php?r=api/get-products HTTP/1.1",
4 upstream: "fastcgi://127.0.0.1:9000", host: "127.0.0.1"

通过探寻 找到原因 当前使用的是项目A，但是A调用了项目B（权限系统） 但是配置的Nginx时只固定了一个9000端口 A占用后；B就无法访问

解决方案：

1.修改nginx.conf 添加端口（红色部分）

http {
include       mime.types;
default_type  application/octet-stream;

#log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
#                  '$status $body_bytes_sent "$http_referer" '
#                  '"$http_user_agent" "$http_x_forwarded_for"';

#access_log  logs/access.log  main;

sendfile        on;
#tcp_nopush     on;

#keepalive_timeout  0;
keepalive_timeout  65;

gzip  on;

upstream fastcgi_backend {
server 127.0.0.1:9001;
server 127.0.0.1:9002;
server 127.0.0.1:9003;
server 127.0.0.1:9004;
server 127.0.0.1:9005;
server 127.0.0.1:9006;
server 127.0.0.1:9007;
}
server {
listen       80;
server_name  localhost;

#charset koi8-r;

#access_log  logs/host.access.log  main;

location / {
root   D:/WNMP/nginx-1.10.3/html;
index  index.html index.htm index.php;
autoindex on;
}

#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   D:/WNMP/nginx-1.10.3/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           D:/WNMP/nginx-1.10.3/html;
fastcgi_pass   fastcgi_backend;
fastcgi_index  index.php;
fastcgi_param  SCRIPT_FILENAME  D:/WNMP/nginx-1.10.3/html$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;
#}
}

2.如果使用快捷脚本启动WNMP，脚本修改（可以将php nginx加入环境变量使用相对路径，我用的绝对路径哈，因为项目多，方便应用不同php版本）

@echo off
start /B  D:/WNMP/php7/php-cgi.exe -b 127.0.0.1:9001  &
start /B  D:/WNMP/php7/php-cgi.exe -b 127.0.0.1:9002  &
