今天有同事找我，說圖片上傳以後，不知道去哪裏了。分析了一下問題，找到緣由以後作了處理，這裏簡要記錄一下。html

問題緣由：nginx

1.首前後臺log並沒有錯誤信息；web

2.撿查了一下瀏覽器，發現network中有報錯，413 Request Entity Too Large，但前臺未報錯。centos

解決辦法：api

1.備份Nginx配置文件；（我的習慣，省得修改以後，若是須要還原，忘記原來的配置）瀏覽器

2.查看當前Nginx配置文件：tomcat

[root@VM_0_16_centos nginx]# cat nginx.conf | grep client_max_body_size測試

client_max_body_size 10m;ui

client_max_body_size 10m;this

client_max_body_size 10m;

結果發現涉及到不少項目，繼續查詢

cat /etc/nginx/nginx.conf | grep -C 10 client_max_body_size

獲得結果以下：

[root@VM_0_16_centos nginx]# cat /etc/nginx/nginx.conf | grep -C 10 client_max_body_size

        }


     location ^~ /qn/prv/ {
            proxy_pass http://private.haochuang.cn/; 
　　　　}

3.修改配置文件：

location / {
            root   html;
            index  index.html index.htm;
   client_max_body_size    1000m;
  }

修改client_max_body_size 配置：

server
{
    listen   80;
    server_name  chat.erp.360buy.com;
    #access_log    /export/servers/nginx/logs/chat.erp.360buy.com;
    location / {
        proxy_pass     http://tomcat;
        client_max_body_size    10m; #表示最大上傳10M，須要多大設置多大。
} }

3.從新加載配置文件，並從新加載nginx：

[root@VM_0_16_centos nginx]# /usr/sbin/nginx -c /etc/nginx/nginx.conf

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
