问题根源有2个:
1,windows上测试
2,使用了nginx
今天在搭建一个laravel项目的时候,遇到了一个问题,Apache可以正常使用,换成nginx就请求超时。排查到使用Guzzlehttp请求自己的时候出错了。
以前也遇到过类似的,当时也是在nginx上,做了一次curl,然后一直超时。
问题原因:
我猜测是php只启动了一个进程,nginx又不维护进程池,单个请求还好,一旦出现自己请求自己,就麻瓜了。因为自己请求自己,不就是递归吗,但是提供递归的服务是单线程,发请求占用了唯一的线程,一直hang到超时。
解决方法:
总共分三步
本地起10个php-cgi进程,分别监听不同的端口。找到自己php所在的目录,CMD下输入cd D:\www\php7.1 php-cgi.exe -b 127.0.0.1:9071 -c D:\www\php7.1 php-cgi.exe -b 127.0.0.1:9072 -c D:\www\php7.1 php-cgi.exe -b 127.0.0.1:9073 -c D:\www\php7.1 php-cgi.exe -b 127.0.0.1:9074 -c D:\www\php7.1 php-cgi.exe -b 127.0.0.1:9075 -c D:\www\php7.1 php-cgi.exe -b 127.0.0.1:9076 -c D:\www\php7.1 php-cgi.exe -b 127.0.0.1:9077 -c D:\www\php7.1 php-cgi.exe -b 127.0.0.1:9078 -c D:\www\php7.1 php-cgi.exe -b 127.0.0.1:9079 -c D:\www\php7.1 php-cgi.exe -b 127.0.0.1:9070 -c D:\www\php7.1 pause
修改nginx.conf配置,对这些进程,做负载均衡处理
events {
worker_connections 1024;
worker_processes auto;
error_log D:/www/nginx/logs/error.log;
pid D:/www/nginx/logs/nginx.pid;
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
#keepalive_timeout 0;
keepalive_timeout 65;
types_hash_max_size 2048;
#gzip on;
include vhost/*.conf;
####注意,下面这一块儿就是对上面进程的管理
upstream php_farm {
server 127.0.0.1:9070 weight=1;
server 127.0.0.1:9071 weight=1;

实际项目中,增加监听(因为是laravel项目遇到的,所以部分conf是兼容laravel的路由逻辑,不是laravel项目的同学只需要注意fast_cgi的配置那里就行)
server {
listen 987;
server_name www.a.com;
root D:/project/laravel/public;
index index.php index.html index.htm;
try_files $uri $uri/ @rewrite;
location @rewrite {
rewrite ^/(.*)$ /index.php?_url=/$1;
location ~ \.php {
add_header Access-Control-Allow-Origin http://localhost;
add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS';
add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization,lang,access-token';
if ($request_method = 'OPTIONS') {
return 204;
