关于免费解决RedHat6.5的:This system is not registered to Red Hat Subscription Managemen
redhat默认自带的yum源需要注册,才能更新,报错:
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
可替换为centos对应的源。 操作如下:
1.检查是否安装yum包。查看RHEL是否安装了yum,若是安装了,那么又有哪些yum包:
rpm -qa |grep yum
2 删除redhat自带的yum包
rpm -qa|grep yum|xargs rpm -e --nodeps(不检查依赖,直接删除rpm包)
rpm -qa |grep yum (查询确认)
[root@localhost ~]#
3.下载新的yum包。使用Centos6.5的yum包
1) 查看版本号和系统类别:
cat /etc/redhat-release
arch
2)根据上一步,找到对应的yum包,然后下载。我的服务器对应的为:
wget
wget
wget
3)执行:
rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm yum-3.2.29-60.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm
如果这一步报错,大底如下:
libc.so.6 is needed by yum-metadata-parser-1.1.2-16.el6.i686
libc.so.6(GLIBC_2.0) is needed by yum-metadata-parser-1.1.2-16.el6.i686
libc.so.6(GLIBC_2.1.3) is needed by yum-metadata-parser-1.1.2-16.el6.i686
libglib-2.0.so.0 is needed by yum-metadata-parser-1.1.2-16.el6.i686
libpthread.so.0 is needed by yum-metadata-parser-1.1.2-16.el6.i686
libpython2.6.so.1.0 is needed by yum-metadata-parser-1.1.2-16.el6.i686
libsqlite3.so.0 is needed by yum-metadata-parser-1.1.2-16.el6.i686
libxml2.so.2 is needed by yum-metadata-parser-1.1.2-16.el6.i686
libxml2.so.2(LIBXML2_2.4.30) is needed by yum-metadata-parser-1.1.2-16.el6.i686
则说明下载安装的yum包与系统版本不匹配,需要重新下载安装。另外,163镜像站点对于6.0~6.5的资源均合并在6的目录下。
4)更换yum源,将原有源删除或备份到别的目下下:
cd /etc/yum.repos.d/
wget
vi CentOS6-Base-163.repo
编辑文件,把文件里面的$releasever全部替换为版本号:6(注意,不是6.5!)最后保存!
替换命令:
[root@node2 ~]# sed -i "s/\$releasever/6/g" -i /etc/yum.repos.d/CentOS6-Base-163.repo
4.清除原有缓存,重建缓存:
clean all
yum makecache
5.更新系统:
yum update
