Linux yum如何卸載軟件包

在Linux系統中，使用YUM（Yellowdog Updater, Modified）包管理器卸載軟件包非常簡單。請按照以下步驟操作：

1. 打開終端（Terminal）。

2. 輸入以下命令，將package_name替換為您要卸載的軟件包名稱：

sudo yum remove package_name

例如，如果您要卸載名為httpd的軟件包，請輸入：

sudo yum remove httpd

3. 按Enter鍵執行命令。系統可能會提示您確認是否要卸載該軟件包。輸入y并按Enter鍵以確認。

4. YUM將開始卸載過程，并顯示相關信息。完成后，您會看到類似以下的輸出：

Loaded plugins: fastestmirror, langpacks

 * extras: centos_mirror.btte.net
