查看Nginx配置文件信息如下：
server {
listen 80;
server_name ra.nerc-edu.com;
location / {
proxy_pass http://172.17.136.237;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
#Proxy Settings
proxy_redirect off;
proxy_set_header Connection close;
proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
proxy_max_temp_file_size 0;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}将其中的proxy_buffer_size 4k;调整到8k proxy_buffer_size 8k; 后测试正常。
