1、查看当前CentOS版本
cat /etc/redhat-release

2、更新源
vim /etc/yum.repos.d/upgrade.repo 并输入以下内容：

CODE:

[base]
name=CentOS-6
failovermethod=priority
baseurl=https://vault.centos.org/6.10/os/x86_64/
baseurl=http://mirrors.sohu.com/centos/6.10/os/x86_64/
gpgcheck=0

[Copy to clipboard]

3、卸载6.x自带的较新的助手，并安装老版[否则会报错]

QUOTE:

yum install http://buildlogs.centos.org/centos/6/upg/x86_64/Packages/openscap-1.0.8-1.0.1.el6.centos.x86_64.rpm -y

4、安装助手
yum install redhat-upgrade-tool preupgrade-assistant-contents -y
如果不成功，用这样的方式

QUOTE:

yum install https://buildlogs.centos.org/centos/6/upg/x86_64/Packages/preupgrade-assistant-1.0.2-33.0.3.el6.centos.x86_64.rpm -y
yum install https://buildlogs.centos.org/centos/6/upg/x86_64/Packages/preupgrade-assistant-contents-0.5.13-1.0.5.el6.centos.noarch.rpm -y
yum install https://buildlogs.centos.org/centos/6/upg/x86_64/Packages/preupgrade-assistant-ui-1.0.2-33.0.3.el6.centos.x86_64.rpm -y
yum install https://buildlogs.centos.org/centos/6/upg/x86_64/Packages/redhat-upgrade-tool-0.7.22-3.el6.centos.noarch.rpm -y

5、检测版本升级的风险，如果控制台输出了错误信息，则需要查询下解决方案并解决
preupg -s CentOS6_7

6、导入CentOS7的key

QUOTE:

rpm --import http://vault.centos.org/centos/7.6.1810/os/x86_64/RPM-GPG-KEY-CentOS-7

7、开始升级

QUOTE:

centos-upgrade-tool-cli --network 7 --instrepo=http://vault.centos.org/centos/7.6.1810/os/x86_64/

8、国内服务器需经过漫长的等待

8、更新完后，重启服务器
reboot
