Nginx Keepalive和DNS解析器 [英] nginx keepalive and dns resolver
本文介绍了Nginx Keepalive和DNS解析器的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我在AWS中有一个nginx实例,该实例具有上游应用程序层.
I have a nginx instance in AWS that has upstream Application layer.
nginx有两个要求
-keepalive
-使用解析器动态解析上游
There are two requirements for nginx
- keepalive
- use resolver to dynamically resolve the upstream
我能够使其中任何一个正常工作.
I am able to make either of them work.
以下是进行Keepalive工作的配置:
Here is the config for making keepalive work:
upstream "backend" {
server "appserver.example.com:443";
keepalive 250;
}
server {
resolver 10.0.0.2 valid=60s;
server_name _;
location / {
proxy_http_version 1.1;
proxy_pass https://backend;
}
}
这是DNS解析器正常工作的配置:
Here is the config for DNS resolver to work:
server {
resolver 10.0.0.2 valid=60s;
server_name _;
set $backend appserver.example.com:443;
location / {
proxy_http_version 1.1;
proxy_pass https://$backend;
}
}
如何在不使用开源NGinx中使用第三方插件的情况下使DNS解析器和keepalive正常工作
How can I get both DNS resolver and keepalive to work without using a third-party plugin in open source NGinx
推荐答案
根据此 jdomain插件
http {
resolver 8.8.8.8;
resolver_timeout 10s;
upstream backend {
jdomain www.baidu.com;
# keepalive 10;
}
server {
listen 8080;
location / {
proxy_pass http://backend;
}
}
}
