1.导入软件源的公钥
sudo apt-key adv –keyserverhkp://keyserver.ubuntu.com:80 –recv EA312927
2.为MongoDB创建软件源list文件
ubuntu12.04
echo “deb http://repo.mongodb.org/apt/ubuntu precise/mongodb-org/3.2 multiverse” | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
ubuntu14.04
echo “deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.2 multiverse” | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
ubuntu16.04
echo “deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse” | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
3.更新软件源并安装mongodb
sudo apt-get update
sudo apt-get install -y mongodb-org
如果想要安装特定的版本，使用下面命令：
sudo apt-get install -y mongodb-org=3.2.9 mongodb-org-server=3.2.9 mongodb-org-shell=3.2.9 mongodb-org-mongos=3.2.9 mongodb-org-tools=3.2.9
4.配置启动文件
如果是ubuntu16.04的版本，需要手动新建/lib/systemd/system/mongod.service文件，并写入下面内容：
[Unit]
Description=High-performance, schema-free document-oriented database
After=network.target
Documentation=https://docs.mongodb.org/manual[Service]
User=mongodb
Group=mongodb
ExecStart=/usr/bin/mongod –quiet –config /etc/mongod.conf[Install]
WantedBy=multi-user.target
5.启动、重启和关闭命令
sudo service mongod start
sudo service mongod restart
sudo service mongod stop
6.mongodb的完全卸载
先停止运行mongodb
sudo service mongod stop
再卸载软件
sudo apt-get purge mongodb-org*
删除数据库和日志文件
sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongodb
