错误信息

使用 yum-config-manager命令时错误信息如下

sudo yum-config-manager \
> --add-repo \
> https://download.docker.com/linux/centos/docker-ce.repo
sudo: yum-config-manager: command not found

解决办法

第一步：

sudo yum -y install yum-utils

如果提示安装成功，则可用执行上述指令，如果提示如下错误，则执行下一步

Package yum-3.4.3-168.el7.centos.noarch already installed and latest version
No package utils available.
Nothing to do

第二步：删除 yum-3.4.3-168.el7.centos.noarch

[planck@NZTCN001 ~]$ sudo yum remove yum-3.4.3-168.el7.centos.noarch
Loaded plugins: fastestmirror

第三步：更换阿里镜像源，重新安装 yum-utils (经过测试，centos 7.9 自带的镜像源安装yum-utils，yum-config-manager 不可用，不知道是系统都是这个问题还是拷贝的系统问题，有待验证)

更换阿里镜像源请参考：yum源-镜像源

再重新安装yum-utils

sudo yum -y install yum-utils
