nginx+tomcat 504 Gateway Time-out异常
应用是nginx+tomcat根据这个错误,是因为tomcat没有及时回应nginx,导致错误.
先使用 fiddler 将页面的请求抓出来.
找到504的请求.然后查找原因.
因为这个请求时间比较长,只有90秒.
所以修改
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
修改成
proxy_connect_timeout 18000; ##修改成半个小时
proxy_send_timeout 18000;
proxy_read_timeout 18000;
附上，nginx配置文件实例
#userwww www;
worker_processes 8;
error_log/usr/local/nginx/logs/nginx_error.logcrit;
pid /usr/local/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
