ubuntu 12.04上安装 mongodb并运行

作者:凯鲁嘎吉 - 博客园 

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: 
executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /tmp/tmp.vcn87sdcvf --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv 7f0ceb10
gpg: requesting key 7f0ceb10 from hkp server keyserver.ubuntu.com

gpg: key 7f0ceb10: public key "richard kreuter <richard@10gen.com>" imported
gpg: no ultimately trusted keys found
gpg: total number processed: 2
gpg:               imported: 2  (rsa: 2)
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
connecting to: test

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
system.indexes
teacher

退出
