openEuler移植案例 | 移植操作指南 | openEuler社区官网

  cat /etc/redhat-release 
CentOS Linux release 7.9.2009 (Core)

需要两台机器，

不通过原因 在待升级节点检查是否有安装x2openEuler-core时, 发现已经安装了,不能作为升级节点。该节点为：

解决方案 请到待升级节点使用‘rpm -qa | grep x2openEuler-core’命令检查是否有安装包, 请换一台机器

下载x2openEuler-core-3.0.0-20240125.x86_64.rpm

wget https://repo.oepkgs.net/openEuler/rpm/openEuler-20.03-LTS-SP1/contrib/x2openEuler/x86_64/Packages/x2openEuler-core-3.0.0-20240125.x86_64.rpmyum install -y x2openEuler-core-3.0.0-20240125.x86_64.rpm 

 更换阿里yum源

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
curl -s -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
curl -s -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.reposed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo

 使用mariadb，需要先设置密码
