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 & start /B D:/WNMP/php7/php-cgi.exe -b 127.0.0.1:9003 & start /B D:/WNMP/php7/php-cgi.exe -b 127.0.0.1:9004 & start /B D:/WNMP/php7/php-cgi.exe -b 127.0.0.1:9005 & start /B D:/WNMP/php7/php-cgi.exe -b 127.0.0.1:9006 & start /B D:/WNMP/php7/php-cgi.exe -b 127.0.0.1:9007 & start /B D:/WNMP/nginx/nginx.exe
