[GitHub] [apisix] spacewander commented on issue #5155: request help: configure etcd mTLS warn certificate host mismatch

We upgrade lua-resty-http in 2.10.0.
Previously, it doesn't send SNI and verify the common name part in the certificate: https://github.com/ledgetech/lua-resty-http/issues/236
This behavior is a bug and is fixed in the latest lua-resty-http.
You need to use `openssl x509 -text -noout -in your_domain_cert` and change the host in the etcd URI to the common name.
For example, assume:
```
$ openssl x509 -text -noout -in t/certs/etcd.pem
Certificate:
Data:
Version: 3 (0x2)
Serial Number:
8d:cc:7a:ef:e0:25:54:cb
Signature Algorithm: sha256WithRSAEncryption
Issuer: C = CN, ST = Zhejiang, L = Hangzhou, O = test, OU = test, CN = blahblah
Validity
Not Before: Oct 28 03:33:02 2020 GMT
Not After : Oct 28 03:33:02 2021 GMT
Subject: C = CN, ST = Zhejiang, L = Hangzhou, O = test, OU = test, CN = etcd.cluster.local
```
You need to change:
```
etcd:
host:
- "https://192.168.27.11:2379"
```
to
```
etcd:
host:
- "https://etcd.cluster.local:2379"
```
