之前一直用RedHat el5 server做服务器使用,但是Redhat的yum需要在线更新是需要收费的,所以后来换了CentOS 6.2版本,但是要想使用它的yum功能,还需要做一些其他的改动,以下是具体的内容:
修改/etc/yum.conf文件,在该文件的后面加上代理服务器ip及端口,如果有用户名和密码的话,也要加上,没有的话就不用了:
proxy=http://ip:port proxy_username=username proxy_password=password
# cd /etc/yum.repos.d/ # wget http://mirrors.163.com/.help/CentOS6-Base-163.repo # vi CentOS6-Base-163.repo
sohu的yum源:wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo
如果第二步wget不可用的话,可以直接在浏览器中得到.repo配置文件。
编辑文件,把文件里面的$releasever全部替换为版本号,即6 最后保存!或者直接把下面的内存拷贝到CentOS6-Base-163.repo文件中即可(已经修改好):

# yum clean all
# yum makecache #将服务器上的软件包信息缓存到本地,以提高搜索安装软件的速度
# yum install vim* #测试域名是否可用
至此,Redhat6可以使用CentOS的yum源在线安装软件了!
最后,可以考虑装个插件,yum install yum-fastestmirror -y,这个会自动选择快的那个源。
如果我在那个目录里放了很多源,怎么知道当前用的是那个呢?如果你没有改yum.conf,那么看/var/cache/yum/文件夹里的一个time开头的文件,就知道了。
