我们利用phpmyadmin上传一个1MB的文件时没有任何问题，但在上传20MB时发现提示

错误日志为： 413 Request Entity Too Large

[error] 24225#0: *44 client intended to send too large body: 20MB, client: x.x.x.x, server: _, request: "POST /phpmyadmin/import.php HTTP/1.1", host: "111cn.net", referrer: "http://www.111cn.net /xxxxxxxxxxxxxxxxxx

1.打开nginx.conf并在http{}字段里添加
2.client_max_body_size 64M; #多少M根据实际情况填写
3.# keepalive_timeout 的值最好也修改一下，否则phpmyadmin上传的时候很容易time out

错误日志二 timed out

Nginx错误日志为:upstream timed out (110: Connection timed out) while reading response header from upstream

解决办法为在server字段里修改proxy_read_timeout的值

proxy_connect_timeout 300;
proxy_read_timeout 300;
proxy_send_timeout 300;
