MongoDB自签名SSL连接:SSL对等证书验证失败

Question

我已按照本指南使用PyMongo进行自签名SSL连接,由Wan Bachtiar创建三个.pem文件; server.pem,client.pem和ca.pem.

我使用的是Ubunut 16.04和mongoDB v3.2.11.

目的是在将mongoDB打开到公共互联网之前保护它.

让我们启动mongod:

$ mongod --auth --port 27017 --dbpath /data/db1 
--sslMode requireSSL --sslPEMKeyFile /etc/ssl/server.pem 
--sslCAFile /etc/ssl/ca.pem --sslAllowInvalidHostnames &

输出:

运行mongod之后,我启动了mongo shell:

$ mongo --port 27017 -u "my username" -p "my password" 
--authenticationDatabase "" --ssl --sslPEMKeyFile /etc/ssl/client.pem 
--sslCAFile /etc/ssl/ca.pem --host tim

输出类似于Marshall Farrier的问题 ; 我们来看一下.

我究竟做错了什么？

Answer 1

经过一些搜索,似乎这个错误是由于主机名"CN"不正确.

来自digitalocean:

每当您生成CSR时,系统都会提示您提供有关证书的信息.此信息称为区分名称(DN).DN中的一个重要字段是公共名称(CN),它应该是您打算使用证书的主机的确切完全限定域名(FQDN).

也来自MongoDB 文档:

如果MongoDB部署使用SSL,则还必须指定--host选项.mongo验证您要连接的mongod或mongos的主机名是否与mongod或mongos的-sslPEMKeyFile证书的CN或SAN匹配.如果主机名与CN/SAN不匹配,则mongo将无法连接.

解:

我重新生成了密钥,将localhost替换为CN = < hostname > 中的任何其他主机名,并完成了Wan Bachtiar的指南.

完成后运行以下命令:

$ mongo --port 27017 -u '<_username_>' -p '<_password_>' 
--authenticationDatabase "<_my db_>" --ssl --sslPEMKeyFile 
/etc/ssl/client.pem  --sslCAFile /etc/ssl/ca.pem --host localhost

注意:MongoDB对谁有权访问mongo shell中的快速测试数据进行严格裁定:

>显示dbs

返回错误.但是,我的用户实际上只能访问"< my db >"中指定的db,因此循环遍历"< my db >"中的行非常有效.
