在尝试安装 yum-utils 的过程中，我遇到了似乎没有启用 repos 的问题。当我似乎需要他这样做时，如何启用yum-config-manager。
[root@spectrumscale ~]# yum install yum-utils
Failed to set locale, defaulting to C

There are no enabled repos.
Run "yum repolist all" to see the repos you have.
You can enable repos with yum-config-manager --enable <repo>

要从特定仓库安装特定包，您可以使用
yum install --enablerepo=name-of-repo name-of-package
假设版本之间可能存在冲突，考虑安装 mariadb 5.5.66 的示例，在我的情况下，我有 2 个 repo mariadb-5 和 mariadb-10，假设如果我想从 mariadb-5 repo 安装，那么我使用
yum install --disablerepo=mariadb-10 --enablerepo=mariadb-5 MariaDB-server MariaDB-client
要启用特定的 repo，您可以使用
yum-config-manager --enable name-of-repo
这是Centos 7.7上的示例

它实际上做了什么？？？
我在/etc/yum.repos.d/得到MariaDB.repo文件，当你使用--enable <repo-name>或--disable <repo-name>时，它会将enabled =的值更改为0或1，基于此，yum repolist将向您显示存储库。
[root@localhost server-setup]# cat /etc/yum.repos.d/MariaDB.repo
[mariadb-10]
name = MariaDB
baseurl = http://yum.mariadb.org/10.4.10/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
[mariadb-5]
name = MariaDB
baseurl = http://yum.mariadb.org/5.5.66/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
enabled = 1

glibc-langpack-en 不见了？可能是yum reinstall glibc-langpack-en
