你在本地把所有依賴都弄到一個文件中 pip freeze > requirements.txt，把該文件上傳到服務(wù)器。

然后再在服務(wù)器上先新建一個python虛擬環(huán)境，再激活虛擬環(huán)境，切換到requirements.txt文件夾目錄下，

通過 pip install -r requirements.txt就會把所有依賴全部裝上。

首先安裝apache：

sudo apt-get install apache2

安裝完畢后，重啟下服務(wù)：

/etc/init.d/apache2 restart

輸入你的密碼，屏幕顯示如下字樣表示重啟完畢：

然后，使用瀏覽器輸入127.0.0.1試一下能否進入apache的歡迎界面，如果進入，則表示apache安裝成功。
