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...

### Other (Cleanup or Flake)

- Adopted a new implementation of watch caches for **list** verbs, using a btree data structure. The new implementation is active by default; you can opt out by disabling the `BtreeWatchCache` feature gate.

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。

## 檢查虛擬環境是否啟動 { #check-the-virtual-environment-is-active }

檢查虛擬環境是否啟動（前面的指令是否生效）。

/// tip

這是**非必需的**，但這是一個很好的方法，可以**檢查**一切是否按預期工作，以及你是否使用了你打算使用的虛擬環境。

## 가상 환경 활성화 여부 확인 { #check-the-virtual-environment-is-active }

가상 환경이 활성화되어 있는지(이전 명령어가 작동했는지) 확인합니다.

/// tip

이 단계는 **선택 사항**이지만, 모든 것이 예상대로 작동하고 있는지, 그리고 의도한 가상 환경을 사용하고 있는지 **확인**하는 좋은 방법입니다.
