怎样在Ubuntu上安装mongoDB

http://songgz.iteye.com/blog/1139345

下面讲述怎样在Ubuntu 11.04上安装mongoDB。 
1. 添加10gen package到source.list。10gen package 包含最新的mongoDB版本， 在文件“/etc/apt/sources.list”的末尾添加下面的行。 

deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen

例如：用nano编辑文件“source.list”并像下面一样添加10gen package。 

$ sudo nano /etc/apt/sources.list

文件: /etc/apt/sources.list 内容如下。 

#...content omitted ...

## This software is not part of Ubuntu, but is offered by third-party
## developers who want to ship their latest software.
deb http://extras.ubuntu.com/ubuntu natty main
deb-src http://extras.ubuntu.com/ubuntu natty main

#mongo repo ###############new line
deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen

2. 添加GPG Key。 
10gen package 要求 GPG key, 导入它 : 

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10

3. 更新 package。 
从新修订 “/etc/apt/sources.list”。 

sudo apt-get update

现在, 一个新的 “mongodb-10gen – 一个面向对像，面向文档的数据库对于安装是有效的。 
4. 安装 mongodb-10gen 
万事具备, 现在可以安装mongoDB package 了: 

sudo apt-get install mongodb-10gen

5. 善后工作。 
现在, mongoDB已被安装, 启动和自动启动mongoDB的脚本被生成到“/etc/init/mongo” 和 “/etc/init.d/mongo“。 另外所有的mongoDB文件被放到 “/usr/bin” 文件夹下。 
主要的配置文件“mongodb.conf”被放到“/etc/mongodb.conf“，在这里可以修改自定义配置。 
文件: mongodb.conf如下。 

# mongodb.conf

# Where to store the data.

# Note: if you run mongodb as a non-root user (recommended) you may
# need to create and set permissions for this directory manually,
# e.g., if the parent directory isn't mutable by the mongodb user.
dbpath=/var/lib/mongodb

#where to log
logpath=/var/log/mongodb/mongodb.log

logappend=true

#port = 27017
#......

6. 验证。 
使用“mongo”连接到mongoDB验证它。 

$ mongo
MongoDB shell version: 1.8.1
connecting to: test
