• While로 돌리면서 Primary DB를 Kill하였을떄 기존 Secondary가 Primary로 넘어가면서 Connection이 되는것을 확인함
• db = client['test']  = test Database 접속
• collection = db['testdb'] = testdb Collection 접속 

• [root@mongo ~]# yum -y install python2-pip
  pip2 install --upgrade pip==20.3
  pip2 install pymongo
  
  [root@mongo ~]# cat mongo.py

  ## Connect Test Database
  db = client['test']

  ## Connect testdb collection
  collection=db['testdb']
