Question

我正在尝试更改默认的data和logs目录，作为新的MongoDB安装的一部分。首先，这就是我安装MongoDB的方式：

$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10

$ echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list

$ sudo apt-get update

$ sudo apt-get install -y mongodb-org

$ echo "mongodb-org hold" | sudo dpkg --set-selections
$ echo "mongodb-org-server hold" | sudo dpkg --set-selections
$ echo "mongodb-org-shell hold" | sudo dpkg --set-selections
$ echo "mongodb-org-mongos hold" | sudo dpkg --set-selections
$ echo "mongodb-org-tools hold" | sudo dpkg --set-selections

$ sudo service mongod start

$ tail /var/log/mongodb/mongod.log

然后，我尝试了一下MongoDB：

$ mongo

> use mydb;

> use mydb2;

> db;

> db.employeedetails.insert({"first" : "XYZ1" , "last" : "XYZ2"});

> db.employeedetails.find();

最后我尝试更改两个相应的路径，但是MongoDB严重失败:(

$ sudo service mongod stop

$ mkdir -p $XZY_PATH/mongodb

$ sudo nano /etc/mongod.conf

# update this:
dbPath: $XZY_PATH/mongodb

# as well as this:
path: $XZY_PATH/mongod.log

$ sudo service mongod start

修改

$ sudo service mongod start返回mongod start/running, process 10777，但我知道$ mongo，我得到：

MongoDB shell version: 3.0.7

我有什么遗漏的吗？

如何在MongoDB中迁移数据和日志？
