生成证书

工具是用的：windows平台  Win64OpenSSL-3_2_0.exe   或  Win64OpenSSL_Light-3_2_0.exe    （建议用：Win64OpenSSL-3_2_0.exe ）

OpenSSL 3.2.0 23 Nov 2023 (Library: OpenSSL 3.2.0 23 Nov 2023)

根证书：
openssl genrsa -out ca.key 2048
openssl req -x509 -new -nodes -key ca.key -sha256 -days 3650 -out ca.pem -subj "/C=CN/ST=GuangDong/O=EMQX/CN=Client"
服务端证书：
openssl genrsa -out emqx.key 2048
openssl req -new -key emqx.key -config openssl.cnf -out emqx.csr
openssl x509 -req -in emqx.csr -CA ca.pem -CAkey ca.key -CAcreateserial -out emqx.pem -days 3650 -sha256 -extensions v3_req -extfile openssl.cnf
客户端证书：
openssl genrsa -out client.key 2048
openssl req -new -key client.key -out client.csr -subj "/C=CN/ST=GuangDong/O=EMQX/CN=Client"
openssl x509 -req -days 3650 -in client.csr -CA ca.pem -CAkey ca.key -CAcreateserial -out client.pem
校验证书的有效性：
openssl verify -CAfile ca.pem emqx.pem
openssl verify -CAfile ca.pem client.pem

常见错误：

Error [ERR_TLS_CERT_ALTNAME_INVALID]: Hostname/IP does not match certificate's altnames: IP: 192.168.10.32 is not in the cert's list:
Error: self signed certificate in certificate chain
Error: Connection refused: Not authorized # 没有设置用户名密码
