2、检测系统可否升级
# 运行检测工具，结果显示可行
preupg -l

3、运行模拟升级工具
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.

7、解决升级过程中的下载速度慢
将上述命令中的地址，更换为 https://www.360docs.net/doc/3114370097.html,/centos/7/os/x86_64/ 速度快多了 :)
8、升级完成重启
安装完成
9、升级中遇到的问题
9.1、安装后重启很久才能重新启动成功
至少需要10分钟才能登录系统，原因未知，后来发现系统日志服务未启动。一直未查明原因。
9.2、首次进入系统，sshd等服务未启动；系统日志服务不可用
发现缺少/usr/lib64/libsasl2.so.2 导致的不能启动，然后升级之后这文件没了，只好
通过 ln -s /usr/lib64/libsasl2.so.3 /usr/lib64/libsasl2.so.2

上述两个服务都可以启动了
# 手动开启
systemctl start rsyslog start
systemctl enable rsys
9.3、yum update 问题
yum update 不能用，发现是python问题，原先centos6.5是2.6.6，系统后python升级2.7.5了，但还是要require2.6.6的库，升级程序没有搞好兼容怎么的
原因; 升级前centos6.5用了6的epel库，现在

升级到centos7后，yum还会找epel6的库依赖，结果一大堆错误。
解决：disable epel6 禁用后即可用
9.4、Protected multilib versions: mesa-libGL-9.2.5-6.20131218.el7_0.i686 != mesa-libGL-10.1.2-2.el6.x86_64
原因：因为升级的原因，安装了两个版本的mesa-libGL
解决：
查找相同的软件包
rpm -aq | grep mesa-libGL
mesa-libGL-devel-9.2.5-5.20131218.el7.x86_64
mesa-libGL-10.1.2-2.el6.x86_64
mesa-libGL-9.2.5-5.20131218.el7.i686
mesa-libGLU-10.1.2-2.el6.x86_64
删除低版本的
yum remove mesa-libGL-devel-9.2.5-5.20131218.el7.x86_64 mesa-libGL-9.2.5-5.20131218.el7.i686
