yum install -y yum-utils出错

前言：（步骤）


# 安装 docker
yum install -y yum-utils
yum-config-manager \
  --add-repo \
  https://download.docker.com/linux/centos/docker-ce.repo
yum install -y docker-ce docker-ce-cli containerd.io
 
# 启动 docker。
systemctl start docker

一、centos8执行yum install -y yum-utils出错

[root@localhost ~]# yum install -y yum-utils
CentOS-8 - AppStream 25 B/s | 38 B 00:01
CentOS-8 - Base 69 B/s | 38 B 00:00
Failed to synchronize cache for repo 'AppStream', ignoring this repo.
Failed to synchronize cache for repo 'BaseOS', ignoring this repo.
Last metadata expiration check: 0:11:10 ago on Mon 20 May 2024 06:26:45 AM PDT.
No match for argument: yum-utils
Error: Unable to find a match

①正确解决步骤：

1.#进入配置文件目录

[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ll
total 44
-rw-r--r--. 1 root root 731 Aug 13 2019 CentOS-AppStream.repo
-rw-r--r--. 1 root root 712 Aug 13 2019 CentOS-Base.repo
-rw-r--r--. 1 root root 798 Aug 13 2019 CentOS-centosplus.repo
-rw-r--r--. 1 root root 1320 Aug 13 2019 CentOS-CR.repo
-rw-r--r--. 1 root root 668 Aug 13 2019 CentOS-Debuginfo.repo
-rw-r--r--. 1 root root 756 Aug 13 2019 CentOS-Extras.repo
-rw-r--r--. 1 root root 338 Aug 13 2019 CentOS-fasttrack.repo
-rw-r--r--. 1 root root 928 Aug 13 2019 CentOS-Media.repo
-rw-r--r--. 1 root root 736 Aug 13 2019 CentOS-PowerTools.repo
-rw-r--r--. 1 root root 1382 Aug 13 2019 CentOS-Sources.repo
-rw-r--r--. 1 root root 74 Aug 13 2019 CentOS-Vault.repo

2.#删除所有的.repo源文件----->很重要

[root@localhost yum.repos.d]# rm *.repo #
rm: remove regular file 'CentOS-AppStream.repo'? y
rm: remove regular file 'CentOS-Base.repo'? y
rm: remove regular file 'CentOS-centosplus.repo'? y
rm: remove regular file 'CentOS-CR.repo'? y
rm: remove regular file 'CentOS-Debuginfo.repo'? y
rm: remove regular file 'CentOS-Extras.repo'? y
rm: remove regular file 'CentOS-fasttrack.repo'? y
rm: remove regular file 'CentOS-Media.repo'? y
rm: remove regular file 'CentOS-PowerTools.repo'? y
rm: remove regular file 'CentOS-Sources.repo'? y
rm: remove regular file 'CentOS-Vault.repo'? y

3.#下载可用的.repo文件

[root@localhost yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
--2024-05-20 06:54:40-- https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo

/etc/yum.repos.d/Ce 100%[===================>] 2.44K --.-KB/s in 0s

2024-05-20 06:54:40 (39.5 MB/s) - ‘/etc/yum.repos.d/CentOS-Base.repo’ saved [2495/2495]

4.#运行yum makecache生成缓存

[root@localhost yum.repos.d]# yum makecache
CentOS-8.5.2111 - AppStream - mirrors.aliyun.co 3.5 MB/s | 8.4 MB 00:02
CentOS-8.5.2111 - Base - mirrors.aliyun.com 13 kB/s | 3.9 kB 00:00
CentOS-8.5.2111 - Extras - mirrors.aliyun.com 2.9 kB/s | 1.5 kB 00:00
Metadata cache created.

5.#运行yum install -y yum-utils

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

完成！！

②错误步骤：（请勿模仿）

#运行yum install -y yum-utils又报错--->原因：没有删除所有的.repo源文件

二、成功在CentOS系统上添加Docker的官方仓库

三、启动 docker

[root@localhost ~]# systemctl start docker

查看版本:

[root@localhost ~]# docker version
