nginx,php 502错误解决

一：错误场景：leyangjun-cc-web.com/api/cc/callback.php 访问返回502

 

二：Nginx错误报错为：

2018/10/22 18:07:09 [crit] 775#0: *41 connect() to unix:/var/run/php7.0-fpm.sock failed

 

三：错误原因

我的Nginx配置文件，配置的不对

server {
     listen       80;
     server_name  leyangjun-cc-web.com;
     root   /www/leyanjgun/cc/src/App/;    index  index.html index.htm index.php;
    access_log /www/log/dev-cc.leyangjun.com-access.log;
     error_log  /www/log/dev-cc.leyangjun.com-error.log error;    location / {
          try_files $uri $uri/ /index.php?$query_string;
     }    location ~ \.php$ {
         fastcgi_pass unix:/run/php7.0-fpm.sock;
         fastcgi_index  index.php;
         fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
         include        fastcgi_params;
         #include     /usr/local/etc/nginx/php-fpm;
         include    fastcgi_params;
     }    error_page  404 403 500 502 503 504  /error.html;
     location = /error.html {
        root   /Users/leyangjun/code/;
     }
 }

就是因为 fastcgi_pass unix:/run/php7.0-fpm.sock; 这个配置，Nginx走的是sock配置，但是我php的www.conf配置文件中没有对sock文件监听，导致Nginx报错

解决方法：

一：vi /usr/local/etc/php/7.1/php-fpm.d/www.conf 增加对文件的监听,能后保存重启服务即可

二：或者直接改用IP形式使用

server {
     listen       80;
     server_name  leyangjun-cc-web.com;
     root   /www/leyanjgun/cc/src/App/;    index  index.html index.htm index.php;
    access_log /www/log/dev-cc.leyangjun.com-access.log;
     error_log  /www/log/dev-cc.leyangjun.com-error.log error;    location ~ ^/(page|aj|api|test)/{
          try_files $uri $uri/ /index.php?$query_string;
     }    location / {
         try_files /index.html =404;
     }    location ~ \.php$ {
         fastcgi_split_path_info ^(.+\.php)(/.+)$;
         fastcgi_pass 127.0.0.1:9000;
         fastcgi_index index.php;
         fastcgi_param MY_ENV 'develop';
         fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
         include fastcgi_params;
     }}

保存重启Nginx服务即可
