* Microsoft SQL Server, etc.

En este ejemplo, usaremos **SQLite**, porque utiliza un solo archivo y Python tiene soporte integrado. Así que puedes copiar este ejemplo y ejecutarlo tal cual.

Más adelante, para tu aplicación en producción, es posible que desees usar un servidor de base de datos como **PostgreSQL**.

allow 9000:9010/tcp ``` ### firewall-cmd For hosts with firewall-cmd enabled (CentOS), you can use `firewall-cmd` command to allow traffic to specific ports. Use below commands to allow access to port 9000 ```sh firewall-cmd --get-active-zones ``` This command gets the active zone(s). Now, apply port rules to the relevant zones returned above. For example if the zone is `public`, use ```sh firewall-cmd --zone=public --add-port=9000/tcp --permanent ``` Note that `permanent` makes sure the rules are persistent...

每次你在這個環境中安裝一個**新的套件**時，都需要**重新啟動**這個環境。

這麼做確保了當你使用一個由這個套件安裝的**終端（<abbr title="command line interface - 命令列介面">CLI</abbr>）程式**時，你使用的是你的虛擬環境中的程式，而不是全域安裝、可能版本不同的程式。
