Ubuntu 12.04上安装 MongoDB 并运行

作者：凯鲁嘎吉 - 博客园 http://www.cnblogs.com/kailugaji/

在Terminal输入

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list
sudo apt-get update
sudo apt-get install mongodb-10gen

结果显示如下：

wrr@ubuntu:~$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
[sudo] password for wrr:

wrr@ubuntu:~$ echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list
deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen
wrr@ubuntu:~$ sudo apt-get update
wrr@ubuntu:~$ sudo apt-get install mongodb-10gen

下载完成后，查看版本号

wrr@ubuntu:~$ mongo -version
MongoDB shell version: 2.4.14

如果不行，执行下面操作

wrr@ubuntu:~$ sudo rm /var/cache/apt/archives/lock
wrr@ubuntu:~$ sudo rm /var/lib/dpkg/lock
wrr@ubuntu:~$ sudo apt-get update

然后在查看版本号即可。以下命令为启动与关闭MongoDB。

sudo service mongodb start
sudo service mongodb stop

以下为启动MongoDB并进行简单操作。

wrr@ubuntu:~$ sudo service mongodb start
mongodb start/running, process 4004
wrr@ubuntu:~$ pgrep mongo -l
4004 mongod
wrr@ubuntu:~$ mongo
MongoDB shell version: 2.4.14

插入数据

> db.student.insert({_id:2018001, sname:'zhangsan', sage:20})
> db.student.save({_id:2018002, sname:'lisi', sage:22})
> db.student.find()
{ "_id" : 2018001, "sname" : "zhangsan", "sage" : 20 }
{ "_id" : 2018002, "sname" : "lisi", "sage" : 22 }

查找数据

> db.student.find({sname:'lisi'})
{ "_id" : 2018002, "sname" : "lisi", "sage" : 22 }
> db.student.find({},{sname:1, sage:1})
{ "_id" : 2018001, "sname" : "zhangsan", "sage" : 20 }
{ "_id" : 2018002, "sname" : "lisi", "sage" : 22 }
> db.student.find({sname:'zhangsan', sage:22})
> db.student.find({$or: [{sage: 22},{sage:25}]})
{ "_id" : 2018002, "sname" : "lisi", "sage" : 22 }

修改数据

将李四的年龄修改为30

> db.student.find().pretty()
{ "_id" : 2018001, "sname" : "zhangsan", "sage" : 20 }
{ "_id" : 2018002, "sname" : "lisi", "sage" : 22 }
> db.student.update({sname:'lisi'},{$set:{sage:30}},false,true)
> db.student.find({sname:'lisi'})
{ "_id" : 2018002, "sname" : "lisi", "sage" : 30 }

删除数据

删除一条学生记录

> db.student.remove({sname:'zhangsan'})
> db.student.find()
{ "_id" : 2018002, "sname" : "lisi", "sage" : 30 }

删除学生数据集

> db.student.drop()
true
> show collections
