amazon aws 初心

-
開始使用amazon aws,用的是一年免費版,我選擇ubuntu server 14.04,但在安裝psycopg2時發生了一些錯誤,,後來參考這位先生的方式解決了
這樣


＄sudo apt-get install python-psycopg2

安裝就成功了

 還就是如果想從外部連接到ec2上面看自己架的網站必須把Security group 的inbound 增加一個你的網站運行中的 TCP port,如下新增Custom TCP Rule  TCP Port 5000

為何是5000？因為網站在port 5000上運行,或是用All traffic也可以
