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
第一步
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
D: cd D:wwwphp7.1 php-cgi.exe -b 127.0.0.1:9071 -c D:wwwphp7.1 php-cgi.exe -b 127.0.0.1:9072 -c D:wwwphp7.1 php-cgi.exe -b 127.0.0.1:9073 -c D:wwwphp7.1 php-cgi.exe -b 127.0.0.1:9074 -c D:wwwphp7.1 php-cgi.exe -b 127.0.0.1:9075 -c D:wwwphp7.1 php-cgi.exe -b 127.0.0.1:9076 -c D:wwwphp7.1 php-cgi.exe -b 127.0.0.1:9077 -c D:wwwphp7.1 php-cgi.exe -b 127.0.0.1:9078 -c D:wwwphp7.1 php-cgi.exe -b 127.0.0.1:9079 -c D:wwwphp7.1 php-cgi.exe -b 127.0.0.1:9070 -c D:wwwphp7.1 pause
第二步
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; server 127.0.0.1:9072 weight=1; server 127.0.0.1:9073 weight=1; server 127.0.0.1:9074 weight=1; server 127.0.0.1:9075 weight=1; server 127.0.0.1:9076 weight=1; server 127.0.0.1:9077 weight=1; server 127.0.0.1:9078 weight=1; server 127.0.0.1:9079 weight=1; } }
第三步
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; } fastcgi_pass php_farm; fastcgi_index /index.php; fastcgi_split_path_info ^(.+.php)(/.+)$; fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } location ~ /.ht { deny all; } }
重启服务,搞定,enjoy it!
