Ubuntu中MongoDB 3.0安装与升级的方法

由于服务器中使用了阿里云提供的源，安装的MongoDB版本太低（好像是MongoDB 2.0.4），MongoDB 3.0出来也有一段时间了，咱也尝尝鲜。下面来介绍我的升级方法，此安装方法来自于MongoDB官网http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/。 （小虾 虎鱼原创）

导入public GPG Key:

Import the public key used by the package management system: The Ubuntu package management tools (i.e. dpkg and apt) ensure package consistency and authenticity by requiring that distributors sign packages with GPG keys. Issue the following command to import the MongoDB public GPG Key:

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

将MongoDB的源地址添加到源中

Create a list file for MongoDB: Create the /etc/apt/sources.list.d/mongodb-org-3.0.list list file using the following command:

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

更新源

Issue the following command to reload the local package database: Reload local package database

sudo apt-get update
安装MongoDB

Install the MongoDB packages: You can install either the latest stable version of MongoDB or a specific version of MongoDB.

安装最新稳定版的MongoDB

sudo apt-get install -y mongodb-org

安装特定版本的MongoDB

Specify each component package individually and append the version number to the package name, as in the following example

sudo apt-get install -y mongodb-org=3.0.1 mongodb-org-server=3.0.1 mongodb-org-shell=3.0.1 mongodb-org-mongos=3.0.1 mongodb-org-tools=3.0.1

最后可以通过命令mongo --version来查看MongoDB的版本号。
