Nginx报错：upstream timed out (110: Connection timed out)和client intended to send too large body【转】

nginx日志报错

2018/01/26 16:36:49 [error] 23327#0: *54953 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 10.68.16.37, server: 10.70.35.119, request: "POST /ApprovalManagement.do?method=approveShow&listType=A&approveType=change&opdb=mod&opinionId=15056 HTTP/1.1", upstream: "http://10.70.35.120:8080/ApprovalManagement.do?method=approveShow&listType=A&approveType=change&opdb=mod&opinionId=15056", host: "10.72.35.119", referrer: "http://10.70.35.119/ApprovalManagement.do?method=flowToList&listType=A"

2018/01/26 17:14:53 [error] 23325#0: *57462 client intended to send too large body: 2008762 bytes, client: 10.2.176.48, server: 10.70.35.119, request: "POST /ApprovalManagement.do?method=checkFileSize HTTP/1.1", host: "10.70.35.119", referrer: "http://10.70.35.119/ApprovalManagement.do?method=approveShow&listType=B&approveType=new&opdb=mod&opinionId=15014"

第一个错误，为代理超时

第二个错误，为client发送body size太大了

解决办法（见绿色部分）：

    server {
        listen       ;
        server_name  10.70.35.119;
        #rewrite ^(.*) https://$10.72.16.112$1 permanent;
        #rewrite ^(.*) https://$server_name$1 permanent;
        location / {
        proxy_pass http://jboss;
                proxy_redirect     off;
                proxy_set_header   Host $host;
    #            proxy_set_header   Host $proxy_host;
    #           proxy_set_header Host $host:$server_port;
                proxy_hide_header Server;
                proxy_set_header X-Real-IP      $remote_addr;
                proxy_set_header X-Forwarded-For $remote_addr;
                client_max_body_size 10m;
                client_body_buffer_size 328k;
                #proxy_buffering off
                proxy_connect_timeout ;
                proxy_send_timeout ;
                proxy_read_timeout ;
                proxy_buffer_size 320k;
                proxy_buffers  320k;
                proxy_busy_buffers_size 640k;
                proxy_temp_file_write_size 640k; 
 
       }

然后重新加载nginx配置文件

service nginx reload

后续记录，设置完以上俩项后，nginx错误日志还是有以上俩个错误，解决办法增加以下参数设置成600s。client_max_body_size参数大于报错大小，暂不调整。

                proxy_connect_timeout ;
                proxy_send_timeout ;
                proxy_read_timeout ;
