一、使用 oracle 提供的脚本完整替换 参考:http://www.tuicool.com/articles/IRbU3e [root@svr205-7 ~]# curl -O https://linux.oracle.com/switch/centos2ol.sh [root@svr205-7 ~]# sh centos2ol.sh [root@svr205-7 ~]# yum upgrade oh yeah,升级完毕,注意upgrade的时候,磁盘空间要足够。 [root@svr205-7 ~]# rpm -qif /etc/redhat-release Name : oraclelinux-release Relocations: (not relocatable) Version : 6Server Vendor: Oracle America Release : 6.0.2 Build Date: Thu 16 Oct 2014 10:08:37 AM CST Install Date: Thu 28 May 2015 01:50:37 PM CST Build Host: ca-buildj3.us.oracle.com Group : System Environment/Base Source RPM: oraclelinux-release-6Server-6.0.2.src.rpm Size : 49559 License: GPL Signature : RSA/8, Thu 16 Oct 2014 10:41:14 AM CST, Key ID 72f97b74ec551f03 Summary : Oracle Linux 6 release file Description : System release and information files [root@svr205-7 ~]# cat /etc/issue Oracle Linux Server release 6.6 Kernel \r on an \m [root@svr205-7 ~]# uname -r 2.6.32-504.23.4.el6.x86_64 [root@svr205-7 ~]# cat /etc/grub.conf # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition.

当前名称:更换centos6的内核为oracleuek内核
