二:php查看后台内容有的栏目出现502?

(1)可能是php读取数据库时间太长或者计算量太大,加大php.ini里的内存;

? ?(2)得到相关的php语句查看打印执行时间;

? ?(3)去掉相关的sql语句试试.

三:413 Request Entity Too Large?

client_max_body_size 50m; ?上传大小限制

五:[error] 9706#0: *203994 FastCGI sent in stderr: "PHP message: PHP Notice:? Undefined index: HTTP_X_REAL_IP in /data/wwwroot/apigmtool.youjoy.tv/app/Controller/Api/Controller.php on line 13" while reading response header from upstream, client: 140.207.91.206, server: apigmtool.youjoy.tv, request

php5会出现这个问题 ,解决在变量前面加上@ ,nginx就不会提示这种警告了
