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: 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 "Totally Legit Signing Key <mallory@example.org>" imported 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 Welcome to the MongoDB shell.
