Linux yum如何卸载软件包

在Linux系统中，使用YUM（Yellowdog Updater, Modified）包管理器卸载软件包非常简单。请按照以下步骤操作：

1. 打开终端（Terminal）。

2. 输入以下命令，将package_name替换为您要卸载的软件包名称：

sudo yum remove package_name

例如，如果您要卸载名为httpd的软件包，请输入：

sudo yum remove httpd

3. 按Enter键执行命令。系统可能会提示您确认是否要卸载该软件包。输入y并按Enter键以确认。

4. YUM将开始卸载过程，并显示相关信息。完成后，您会看到类似以下的输出：
