Linux系统yum的安装、升级、卸载命令详解

2024-04-06 04:23:54 北京举报

简介： Linux系统yum的安装、升级、卸载命令详解

+关注继续查看

yum安装命令

yum 安装软件包的命令基本格式为：

[root@localhost yum.repos.d]# yum -y install 包名

其中：

install：表示安装软件包。
-y：自动回答 yes。如果不加 -y，那么每个安装的软件都需要手工回答 yes；

例如使用此 yum 命令安装 gcc：

[root@localhost yum jepos.d]#yum -y install gcc
#使用yum自动安装gcc

gcc 是 C 语言的编译器，鉴于该软件包涉及到的依赖包较多，建议使用 yum 命令安装。

yum 升级命令

使用 yum 升级软件包，需确保 yum 源服务器中软件包的版本比本机安装的软件包版本高。 yum 升级软件包常用命令如下：

yum -y update：升级所有软件包。不过考虑到服务器强调稳定性，因此该命令并不常用。
yum -y update 包名：升级特定的软件包。

yum 卸载命令

使用 yum 卸载软件包时，会同时卸载所有与该包有依赖关系的其他软件包，即便有依赖包属于系统运行必备文件，也会被 yum 无情卸载，带来的直接后果就是使系统崩溃。除非你能确定卸载此包以及它的所有依赖包不会对系统产生影响，否则不要使用 yum 卸载软件包。 yum 卸载命令的基本格式如下：

[root@localhost yum.repos.d]# yum remove 包名
#卸载指定的软件包

例如，使用 yum 卸载 samba 软件包的命令如下：

[root@localhost yum.repos.d]# yum remove samba
#卸载samba软件包

域名到期后多久可以注册

域名到期后，并不会立即被他人注册，而是经历了一定的释放周期。这是因为域名注册机构为了保护域名的合法权益，会设置一段时间用于处理续期、赎回以及其他相关操作。
