MongoDB是不是在Ubuntu 16.04開始

我設置的MongoDB在Ubuntu 16.04有：MongoDB是不是在Ubuntu 16.04開始

echo "deb http://repo.mongodb.org/apt/debian wheezy/mongodb-org/3.0 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list 
sudo apt-get update 
sudo apt-get install -y mongodb-org

但我得到這些錯誤，當我嘗試啓動服務：

**~$** systemctl start mongodb 
Failed to start mongodb.service: Unit mongodb.service is masked. 

**~$** systemctl start mongod 
Failed to start mongod.service: Unit mongod.service not found. 

**~$** sudo service mongod start 
Failed to start mongod.service: Unit mongod.service not found. 

**~$** mongod 
mongod --help for help and startup options

但是當我檢查狀態是積極的，請幫助我。我不知道我必須做什麼！

我以前工作的C9，但它有這麼多的問題，是緩慢的，我需要的MongoDB爲我的項目工作（對不起，我的壞簡體）
