      CentOS 6.1操作系統升級至Centos 7.7.1908

      時間:2024-06-07來源:風信官網 點擊: 2856次
      CentOS 6.1操作系統升級至Centos 7.7.1908操作過程記錄步驟如下:
       
      1.查看下當前的系統版本
       
      cat /etc/redhat-release
       
      CentOS release 6.10 (Final)
       
      2.配置更新源
       
      vi /etc/yum.repos.d/upgradetool.repo
       
      [upgrade]
      name=upgrade
      baseurl=http://vault.centos.org/centos/6/upg/x86_64/
      enable=1
      gpgcheck=0
       
      安裝更新助手
       
      由于centos 6.5自帶的助手之一版本較高,所以需要卸載了裝個更老的:
      yum erase openscap -y
      yum install redhat-upgrade-tool preupgrade-assistant-contents -y
       
      如果提示以下錯誤信息:
      Loaded plugins: fastestmirror, security
      Setting up Install Process
