序

想更新rh6.7企业版上的gcc,才能编译手头的工程.
先要使yum可以更新非本地的软件,再从外网升级yum.
实验还没做完,先记录这些.

实验

rh企业版要升级,正常是要有企业账号. 个人账号不好使.
网上的方法是找centos版的yum配置文件进行修改和替换.
网上有个原版centos的rhel-source.repo,下载后,将文件中的$releasever文本都换成6,然后替换到/etc/yum.repos.d/rhel-source.repo.

#
# @file rhel-souce.repo
# please replace all $releasever to 6,means the file's configure is for centos6
# after modify,please replace to /etc/yum.repos.d/rhel-source.repo
#

升级yum

替换完配置文件后,可以从外网进行yum了.
现在升级yum,写了一个很挫的脚本来进行yum升级.
用wget时,发现centos镜像站点上的目录结构和文件名已经变了,如果以后还要用这个脚本,要去镜像站点先确认下,文件名称和位置,如果变了,替换脚本中的对应文件名称和下载点url.
如果将博客中的脚本贴到.sh后,需要在vi或si中处理一下回车符号为unix回车符号.

总结

升级完yum,就可以去升级gcc到新版本了. 实验还没做. 不升级linux版本,只升级部分组件(e.g. yum,gcc),还是有潜在问题的. 如果用户那的计算机本来运行的溜溜的,谁也不能保证他用的现有软件是否会依赖升级后的组件. 最好的方法,还是不升级用户计算机上的任何组件.
