Go实战--golang使用ssl连接MongoDB(mgo)

前端之家收集整理的这篇文章主要介绍了Go实战--golang使用ssl连接MongoDB(mgo)前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

生命不止,继续 go go go!!!

之前写过关于golang如何使用mongodb的文章
Go实战–golang中使用MongoDB(mgo)

文中主要介绍了Windows下如何安装mongodb,mongodb的简单命令,golang如何操作mongodb,以及使用golang+mongodb创建的微服务。

今天继续深深耕一点。

Windows下mongo使用配置文件

创建一个配置文件,例如命名为mongod.cfg

创建一个日志文件,例如命名为mongodb.log

创建一个存储数据的文件

配置文件中键入以下内容

systemLog:
  destination: file
  path: "D:\\mongodb_log\\mongodb.log"
  logAppend: true
storage:
  dbPath: "D:\\mongodb_data\\db"
security:
  authorization: enabled

cmd键入以下命令:

mongod --config "d:\Program Files\MongoDB\conf\mongod.cfg"

此时查看mongodb.log内容为:

使用tail查看实时日志

此时,你是不是很怀念linux呢,实时查看日志。我们也可以在windows上使用tail命令

下载
http://files.cnblogs.com/hantianwei/tail.zip

解压,添加到环境变量

重启一个cmd,键入:

tail -f D:\mongodb_log\mongodb.log

为mongodb增加证书

生成证书
命令:

openssl req -newkey rsa:2048 -new -x509 -days 365 -nodes -out mongodb-cert.crt -keyout mongodb-cert.key

需要填写一些信息:

λ openssl req -newkey rsa:2048 -new -x509 -days 365 -nodes -out mongodb-cert.crt -keyout mongodb-cert.key
Generating a 2048 bit RSA private key
..........+++
..............................................+++
writing new private key to 'mongodb-cert.key'
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,If you enter '.',the field will be left blank.
-----
Country Name (2 letter code) [AU]:cn State or Province Name (full name) [Some-State]:beijing Locality Name (eg,city) []:beijing Organization Name (eg,company) [Internet Widgits Pty Ltd]:superwang Organizational Unit Name (eg,section) []:wangshubo Common Name (e.g. server FQDN or YOUR name) []:wangshubo Email Address []:wangshubo1989@126.com

生成pem

cat mongodb-cert.key mongodb-cert.crt > mongodb.pem

修改配置文件
mongod.cfg文件增加ssl:

systemLog:
  destination: file
  path: "D:\\mongodb_log\\mongodb.log"
  logAppend: true
storage:
  dbPath: "D:\\mongodb_data\\db"
security:
  authorization: enabled
net:
  ssl:
    mode: requireSSL
    PEMKeyFile: "D:\\Program Files\\MongoDB\\mongodb.pem"

启动mongo服务

mongod --config "d:\Program Files\MongoDB\conf\mongod.cfg"

通过tail查看日志:

启动mongodb客户端
cmd输入命令:

mongo

如下:

MongoDB shell version v3.4.6
connecting to: mongodb://127.0.0.1:27017
2017-08-24T17:38:05.507+0800 I NETWORK  [thread1] Socket recv() 远程主机强迫关闭了一个现有的连接。 127.0.0.1:27017

exception: connect Failed

没有证书的原因

通过ssl启动mongodb客户端
cmd键入命令:

mongo --ssl --sslPEMKeyFile "D:\Program Files\MongoDB\mongodb.pem" --sslAllowInvalidCertificates

如下:

MongoDB shell version v3.4.6
connecting to: mongodb://127.0.0.1:27017
2017-08-24T17:47:06.597+0800 W NETWORK  [thread1] SSL peer certificate validation Failed: self signed certificate
2017-08-24T17:47:06.597+0800 W NETWORK  [thread1] The server certificate does not match the host name. Hostname: 127.0.0.1 does not match CN: wangshubo
MongoDB server version: 3.4.6

这里需要提醒的是,千万不要忘记--sslAllowInvalidCertificates,因为这是我们自制的证书。

解决not authorized on admin to execute command的问题
1.不带ssl启动mongod

mongod.exe --dbpath d:\mongodb_data\db

2.客户端端连接

mongo

3.切换到admin

use admin

4.创建role

> db.createRole({role:'sysadmin',roles:[],privileges:[{resource:{anyResource:true},actions:['anyAction']}]})
{
        "role" : "sysadmin","roles" : [ ],"privileges" : [
                {
                        "resource" : {
                                "anyResource" : true
                        },"actions" : [
                                "anyAction"
                        ]
                }
        ]
}

5.切换到test,创建用户

> use test
switched to db test
> db.createUser({user:'wangshubo',pwd:'dabaojian',roles:[{role:'sysadmin',db:'admin'}]})
Successfully added user: {
        "user" : "wangshubo","roles" : [
                {
                        "role" : "sysadmin","db" : "admin"
                }
        ]
}

6.重新启动mongodb服务端,使用认证

mongod --config "d:\Program Files\MongoDB\conf\mongod.cfg"

7.使用ssl连接

mongo --ssl --sslPEMKeyFile "D:\Program Files\MongoDB\mongodb.pem" --sslAllowInvalidCertificates --sslAllowInvalidHostnames

8.使用
使用test

use test

查看数据库

> show dbs
2017-08-25T10:36:48.550+0800 E QUERY    [thread1] Error: listDatabases Failed:{
        "ok" : 0,"errmsg" : "not authorized on admin to execute command { listDatabases: 1.0 }","code" : 13,"codeName" : "Unauthorized"
} :

shellHelper.show@src/mongo/shell/utils.js:769:19
shellHelper@src/mongo/shell/utils.js:659:15
@(shellhelp2):1:1

9.不要灰心,操作前先认证就好了

> db.auth("wangshubo","dabaojian")
1
> show dbs
admin  0.000GB
local  0.000GB
store  0.000GB
test   0.000GB

golang通过ssl连接mongodb

还记得吗,昨天写了一篇日志:
Go实战–golang中使用HTTPS以及TSL(.crt、.key、.pem区别以及crypto/tls包介绍)

所以,关于golang中介绍不再过多赘述,直接可以上代码了。为了方便起见,我直接把证书内容写到了程序里面。

    "crypto/tls"
    "crypto/x509"
    "fmt"
    "log"
    "net"

    "gopkg.in/mgo.v2/bson"
