标签：upgrade CentOS centos preupgrade 升级 失败 usr openscap xsl
操作系统: CentOS6.10
本系统源
#wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
1.查看当前CentOS版本
[root@sky9890 sky9890]# cat /etc/redhat-release
CentOS release 6.10 (Final)
2.更新源
#vim /etc/yum.repos.d/upgrade.repo
[upgrade]
name=upgrade
baseurl=https://buildlogs.centos.org/centos/6/upg/x86_64/
enable=1
gpgcheck=0
3.卸载6.x自带的较新的助手，并安装老版,否则会报错。
#先删除旧版本
#yum erase openscap -y
#以下无法连接
#yum install http://dev.centos.org/centos/6/upg/x86_64/Packages/openscap-1.0.8-1.0.1.el6.centos.x86_64.rpm -y
#以下两个连接都有效
yum install ftp://ftp.pbone.net/mirror/ftp.scientificlinux.org/linux/scientific/6.5/x86_64/updates/fastbugs/openscap-1.0.8-1.el6_5.x86_64.rpm -y
yum install https://buildlogs.centos.org/centos/6/upg/x86_64/Packages/openscap-1.0.8-1.0.1.el6.centos.x86_64.rpm -y
4.安装升级系统助手
#利用到upgrade.repo源
#yum install redhat-upgrade-tool preupgrade-assistant-contents -y
5.检测是否可以升级
#preupg -s CentOS6_7
Preupg tool doesn't do the actual upgrade.
Please ensure you have backed up your system and/or data in the event of a failed upgrade
that would require a full re-install of the system from installation media.

#尝试过多个系统版本，均无法升级。
