如何在 CentOS 中添加、启用和禁用一个仓库 ====== 在基于 RPM 的系统上,例如 RHEL、CentOS 等,我们中的许多人使用 yum 包管理器来管理软件的安装、删除、更新、搜索等。 Linux 发行版的大部分软件都来自发行版官方仓库。官方仓库包含大量免费和开源的应用和软件。它很容易安装和使用。 由于一些限制和专有问题,基于 RPM 的发行版在其官方仓库中没有提供某些包。另外,出于稳定性考虑,它不会提供最新版本的核心包。 为了克服这种情况,我们需要安装或启用需要的第三方仓库。对于基于 RPM 的系统,有许多第三方仓库可用,但所建议使用的仓库很少,因为这些不会替换大量的基础包。 建议阅读: - [在 RHEL/CentOS 系统中使用 YUM 命令管理包][1] - [在 Fedora 系统中使用 DNF (YUM 的分支) 命令来管理包][2] - [命令行包管理器和用法列表][3] - [Linux 包管理器的图形化工具][4] 这可以在基于 RPM 的系统上完成,比如 RHEL, CentOS, OEL, Fedora 等。 * Fedora 系统使用 `dnf config-manager [options] [section …]` * 其它基于 RPM 的系统使用 `yum-config-manager [options] [section …]` ### 如何列出启用的仓库 只需运行以下命令即可检查系统上启用的仓库列表。 对于 CentOS/RHEL/OLE 系统: ``` # yum repolist Loaded plugins: fastestmirror, security Loading mirror speeds from cached hostfile repo id repo name status base CentOS-6 - Base 6,706 extras CentOS-6 - Extras 53 updates CentOS-6 - Updates 1,255 repolist: 8,014 ``` 对于 Fedora 系统: ``` # dnf repolist ``` ### 如何在系统中添加一个新仓库 每个仓库通常都提供自己的 `.repo` 文件。要将此类仓库添加到系统中,使用 root 用户运行以下命令。在我们的例子中将添加 EPEL 仓库 和 IUS 社区仓库,见下文。 但是没有 `.repo` 文件可用于这些仓库。因此,我们使用以下方法进行安装。 对于 EPEL 仓库,因为它可以从 CentOS 额外仓库获得,所以运行以下命令来安装它。 ``` # yum install epel-release -y ``` 对于 IUS 社区仓库,运行以下 bash 脚本来安装。 ``` # curl 'https://setup.ius.io/' -o setup-ius.sh # sh setup-ius.sh ``` 如果你有 `.repo` 文件,在 RHEL/CentOS/OEL 中,只需运行以下命令来添加一个仓库。 ``` # yum-config-manager --add-repo http://www.example.com/example.repo Loaded plugins: product-id, refresh-packagekit, subscription-manager adding repo from: http://www.example.com/example.repo grabbing file http://www.example.com/example.repo to /etc/yum.repos.d/example.repo example.repo | 413 B 00:00 repo saved to /etc/yum.repos.d/example.repo ``` 对于 Fedora 系统,运行以下命令来添加一个仓库: ``` # dnf config-manager --add-repo http://www.example.com/example.repo adding repo from: http://www.example.com/example.repo ``` 如果在添加这些仓库之后运行 `yum repolist` 命令,你就可以看到新添加的仓库了。Yes,我看到了。 注意:每当运行 `yum repolist` 命令时,该命令会自动从相应的仓库获取更新,并将缓存保存在本地系统中。 ``` # yum repolist Loaded plugins: fastestmirror, security Loading mirror speeds from cached hostfile epel/metalink | 6.1 kB 00:00 * epel: epel.mirror.constant.com * ius: ius.mirror.constant.com ius | 2.3 kB 00:00 repo id repo name status base CentOS-6 -
