[GitHub] [apisix] amazing-gao opened a new issue #5363: bug: configure upstream `Hostname` does not work
amazing-gao opened a new issue #5363:
URL: https://github.com/apache/apisix/issues/5363
### Issue description
I configure upstream `Hostname` to `Use the domain or IP from Node List`, but upstream received hostname still be `Keep the same Host from client request`.
Proxy request log show it uses `host: "10.2.130.145:9080"`, not my upstream node IP.
```
2021/10/29 01:11:21 [info] 44#44: *5416719 [lua] balancer.lua:349: run(): proxy request to 10.51.167.92:7007 while connecting to upstream, client: 10.2.230.47, server: _, request: "GET /user/info?test=abc HTTP/1.1", host: "10.2.130.145:9080"
```
My upstream deployed on k8s and has an envoy gateway. if HTTP `host` is wrong, will get 404.
apisix: `10.2.130.145:9080`
upstream: `10.51.167.92:7007`
### Environment
- apisix version (cmd: `apisix version`): `2.10.0`
- OS (cmd: `uname -a`): `Linux c0fff832da83 5.4.0-48-generic #52-Ubuntu SMP Thu Sep 10 10:58:49 UTC 2020 x86_64 Linux`
- OpenResty / Nginx version (cmd: `nginx -V` or `openresty -V`): `nginx version: openresty/1.19.3.1`
- etcd version, if have (cmd: run `curl http://127.0.0.1:9090/v1/server_info` to get the info from server-info API): `3.4.9`
- apisix-dashboard version, if have: `2.9.0`
- the plugin runner version, if the issue is about a plugin runner (cmd: depended on the kind of runner):
- luarocks version, if the issue is about installation (cmd: `luarocks --version`): `3.7.0`
### Steps to reproduce
1. upstream config:
```json
{
"nodes": [
{
"host": "10.51.167.92",
"port": 7007,
"weight": 1
}
],
"retries": 1,
"timeout": {
"connect": 6,
"send": 6,
"read": 6
},
"type": "roundrobin",
"scheme": "http",
"pass_host": "node",
"name": "yyyyy",
"keepalive_pool": {
"idle_timeout": 60,
"requests": 1000,
"size": 320
}
}
```
2. route config:
```json
{
"uri": "/*",
"name": "xxxx",
"upstream_id": "378825999736898241",
"status": 1
}
```
3. curl apisix gateway get 404
```sh
curl -v http://10.2.130.145:9080/user/info\?test\=abc
* Trying 10.2.130.145...
* TCP_NODELAY set
* Connected to 10.2.130.145 (10.2.130.145) port 9080 (#0)

> Host: 10.2.130.145:9080
> User-Agent: curl/7.64.1
> Accept: */*

### Actual result
curl apisix gateway get 404
### Error log
1. access.log
```

Posted by GitBox <gi...@apache.org>.

URL: https://github.com/apache/apisix/issues/5363#issuecomment-954412031
> Proxy request log show it uses `host: "10.2.130.145:9080"`, not my upstream node IP.
This is the expected behavior, since the host in client's request is `10.2.130.145:9080`, see:
> ```shell
> * Trying 10.2.130.145...
> * TCP_NODELAY set
> * Connected to 10.2.130.145 (10.2.130.145) port 9080 (#0)
> > GET /user/info?test=abc HTTP/1.1
> > Host: 10.2.130.145:9080
> > User-Agent: curl/7.64.1
> > Accept: */*
> ```
you need to use `proxy-rewrite` plugin to rewrite the host.
