nginx根据header分流

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.com

curl -H “version:1” http://test.nerdaye.com
