我检查了/etc/mongod.conf的权限：
vagrant@trusty64:/vagrant/test$ sudo docker exec -it mongodb ls -l /etc/mongod.conf
-rw-r--r-- 1 root root 472 Jun 22 00:09 /etc/mongod.conf
然后，我检查了它的相应内容：
vagrant@trusty64:/vagrant/test$ sudo docker exec -it mongodb cat /etc/mongod.conf
## mongodb.conf, this file is enforced by puppet.
##
## Note: http://docs.mongodb.org/manual/reference/configuration-options/
##
## where and how to store data.
storage:
dbPath: /var/lib/mongodb
journal:
enabled: true
## where to write logging data.
systemLog:
destination: file
logAppend: true
path: /var/log/mongodb/mongod.log
## network interfaces

bindIp: 0.0.0.0
## mongodb process
processManagement:
pidFilePath: /var/run/mongod.pid
## role-based access controls
#security:
# authorization: enabled
接下来，我添加了一个mongodb用户，调整了mongod.conf，然后重新启动了mongod进程：
vagrant@trusty64:/vagrant/test$ sudo docker exec -it mongodb sudo mongo mongodb://mongodb:27017 --eval "db.getSiblingDB('admin'); db.createUser({\
user: 'authenticated',\
pwd: 'password',\
roles: [\
'readWrite',\
'userAdmin',\
'dbAdmin',\
{ role: 'readWrite', db: 'dataset' },\
{ role: 'userAdmin', db: 'dataset' },\
{ role: 'dbAdmin', db: 'dataset' },\
]\
},\
{ w: 'majority' , wtimeout: 5000 } )" --quiet
sudo docker exec -it mongodb sudo sed -i "/#[[:space:]]*security:/s/^#//g" /etc/mongod.conf
sudo docker exec -it mongodb sudo sed -i "/#[[:space:]]*authorization:[[:space:]]*enabled/s/^#//g" /etc/mongod.conf
sudo docker restart mongodb
现在，我已准备好尝试从docker容器中实现pymongo连接器：
vagrant@trusty64:/vagrant/test$ sudo docker exec -it webserver python

我被Authentication failed拒绝了。我确认我们的/etc/mongod.conf配置文件已根据authorization指令进行了正确调整：

答案 0 :(得分：0)
我之前在IRC上与您交谈过。
问题在于，当您使用
行创建用户时vagrant@trusty64:/vagrant/test$ sudo docker exec -it mongodb sudo mongo mongodb://mongodb:27017 --eval "db.getSiblingDB('admin'); db.createUser(...
您实际上并未将db变量设置为兄弟（admin）数据库。您只是调用一个返回数据库的函数。
您需要在shell中使用命令db = db.getSiblingDB('admin');将当前数据库设置为“admin”数据库。
您也可以使用简写use admin。
或者您可以在您的mongod调用中包含admin数据库，并完全放弃eval'd db开关。数据库名称通常是mongod可执行文件的第一个参数。我不是100％肯定它将如何转换为您的docker命令。
也许vagrant@trusty64:/vagrant/test$ sudo docker exec -it mongodb sudo mongo admin mongodb://mongodb:27017 --eval "db.createUser(...
干杯！
