nginx根据header分流

Posted 2023-01-24

OS：Centos 7.6
 version: nginx 1.18.0
 nginx根据header分流
 不同header头分发到不同节点
 同一域名路径根据不同header头分发到不同节点
 主要配置 通过 http_version 判断版本，转发至不同upstream。test.nerdaye.com.conf
 server 
 listen 80;
 server_name test.nerdaye.com;
 underscores_in_headers on;
 access_log /apps/nginx/log/test.nerdaye.com.access.log;
 error_log /apps/nginx/log/test.nerdaye.com.error.log;location / 
proxy_redirect off;
proxy_http_version 1.1;
proxy_set_header Connection "";
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X_CUSTOM_HEADER $http_host;
if ($http_version = 1)
     proxy_pass http://hl_v1_node;

    if ($http_version = 2)
     proxy_pass http://hl_v2_node;
    
 
upstream
 upstream hl_v1_node 
 server 10.1.1.1:8080 id=102 weight=10;
 keepalive 100;
 check interval=3000 rise=2 fall=5 timeout=1000 type=tcp;
 upstream hl_v2_node 
 server 10.1.1.2:8080 id=102 weight=10;
 keepalive 100;
 check interval=3000 rise=2 fall=5 timeout=1000 type=tcp;
 测试方法
 curl -H “version:2” http://test.nerdaye.comcurl -H “version:1” http://test.nerdaye.com
