1、yum install 涌现：There are no enabled repositories in "/etc/yum.repos.d", "/etc/yum/repos.d", "/etc/distro.repos.d".
这是yum install git涌现的缺点
办理办法
从华为云获取镜像库文件
wget -O /etc/yum.repos.d/openEulerOS.repo https://repo.huaweicloud.com/repository/conf/openeuler_x86_64.repo
然后修正openEulerOS.repo文件内容
①将repo.huaweicloud.com/openeuler 改为 repo.openeuler.org
②将openEuler-20.03-LTS 改为 openEuler-22.03-LTS-SP1。由于openEuler是22.03-LTS-SP1版本
③[openEuler-EPOL]的baseurl中须要在EPOL后添加/main/
末了修正后如下内容
[openEuler-source]name=openEuler-sourcebaseurl=https://repo.openeuler.org/openEuler-22.03-LTS-SP1/source/enabled=1gpgcheck=1gpgkey=https://repo.openeuler.org/openEuler-22.03-LTS-SP1/source/RPM-GPG-KEY-openEuler[openEuler-os]name=openEuler-osbaseurl=https://repo.openeuler.org/openEuler-22.03-LTS-SP1/OS/x86_64/enabled=1gpgcheck=1gpgkey=https://repo.openeuler.org/openEuler-22.03-LTS-SP1/OS/x86_64/RPM-GPG-KEY-openEuler[openEuler-everything]name=openEuler-everythingbaseurl=https://repo.openeuler.org/openEuler-22.03-LTS-SP1/everything/x86_64/enabled=1gpgcheck=1gpgkey=https://repo.openeuler.org/openEuler-22.03-LTS-SP1/everything/x86_64/RPM-GPG-KEY-openEuler[openEuler-EPOL]name=openEuler-epolbaseurl=https://repo.openeuler.org/openEuler-22.03-LTS-SP1/EPOL/main/x86_64/enabled=1gpgcheck=0
2、yum install 涌现：Error: Unable to find a match: yum-utils
从阿里云获取镜像库文件
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
3、yum install 涌现：Error: Unable to find a match: docker-ce从阿里云获取镜像库文件
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
然后须要将docker-ce.repo文件中 $releaserver 改为 8
