【问题描述】：

我在我的 linux 机器上创建了自签名证书，我在其中提供了与该 linux 的 IP 相同的证书 CN 我已将它们添加到 mongodb.conf 并重新启动服务器我可以通过命令连接

mongo --ssl --sslPEMKeyFile /etc/ssl/mongodbcerts/mongodb.pem --sslCAFile /etc/ssl/mongodbcerts/ca.pem

但是当我尝试从 nodeJS mongoose 连接时，我遇到了类似的错误

MongooseServerSelectionError: Hostname/IP does not match certificate's altnames: IP: XXX.xx.x.xx is not in the cert's list:

我的连接mongodb的nodejs代码如下

const connectionOptions = { useCreateIndex: true,
     useNewUrlParser: true, 
     useUnifiedTopology: true,
     useFindAndModify: false ,
     server:{
    ssl: true,
    sslValidate:true,
    sslCA: require('fs').readFileSync("/etc/ssl/mongodbcerts/ca.pem"),
    sslKey:require('fs').readFileSync("/etc/ssl/mongodbcerts/mongodb.key"),
    sslCert:require('fs').readFileSync("/etc/ssl/mongodbcerts/mongodb.crt")
            }
};

let mongo_url="mongodb://username:password@IPaddress/DB"
console.log(mongo_url)
mongoose.connect(mongo_url,connectionOptions).then(() => console.log( 'Database Connected' ))
.catch(err => console.log( err ));;

请告诉我错误

【解决方案1】：

我犯的错误是我创建了以通用名称 (CN) 作为 IP 地址 (XXX.xx.x.xx) 的自签名证书，但我们需要创建以 CN 作为主机名的自签名证书。要获取主机名，请打开 mongo shell 并执行以下命令：

>getHostName()

您将使用该 VM 的主机名并创建具有相同主机名的自签名证书，并尝试使用 mongoose nodejs 连接。它会起作用的。支持文档：https://mongoosejs.com/docs/tutorials/ssl.html

【解决方案2】：

我最近遇到了this issue。从 MongoDB 4.2 开始，在进行 SAN 比较时，MongoDB 也支持 IP 地址比较。您可以在 CN 字段中使用 IP 地址，但请确保您的 openssl 配置文件在 alt_names 部分中包含您的服务器 IP 地址。

这是官方 MongoDB 文档中提供的示例 cnf 文件 -

default_bits = 4096
default_keyfile = myTestServerCertificateKey.pem    ## The default private key file name.
