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"

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 ;
