ubuntu16.04安装mongodb3.4

参考

  1. Import the public key used by the package management system. 
      sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 0C49F3730359A14518585931BC711F9BA15703C6
  2. Create a list file for MongoDB. 
      echo "deb [ arch=amd64,arm64 ] http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list

    上面是官方的镜像源，国内下载特别慢，故换成阿里源：

      echo "deb [ arch=amd64,arm64 ] http://mirrors.aliyun.com/mongodb/apt/ubuntu xenial/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list
  3. Reload local package database. 
      sudo apt-get update
  4. Install the latest stable version of MongoDB. 
      sudo apt-get install -y mongodb-org

    Run MongoDB Community Edition

    The MongoDB instance stores its data files in /var/lib/mongodb and its log files in /var/log/mongodb by default, and runs using the mongodb user account. You can specify alternate log and data file directories in /etc/mongod.conf.

  5. Start MongoDB. 
      sudo service mongod start
  6. erify that MongoDB has started successfully.
    查看mongodb的日志文件，最后一行会输出： 
      [initandlisten] waiting for connections on port <port>
  7. Stop MongoDB. 
      sudo service mongod stop
  8. Restart MongoDB. 
      sudo service mongod restart

    Uninstall MongoDB Community Edition

  9. Stop MongoDB.
  10. Remove packages: 
      sudo apt-get purge mongodb-org*
  11. Remove MongoDB databases and log files.
