# 源码升级glibc有很多依赖关系，rhel的yum源无法使用，使用centos的yum源进行升级
1、卸载rhel6.2默认的yum
# rpm -qa|grep yum|xargs rpm -e --nodeps 2、安装centos6.2的yum软件
# ll yum-*
-rw-r--r--. 1 root root 1010148 Dec92011 yum-3.2.29-22.el6.centos.noarch.rpm
-rw-r--r--. 1 root root 27224 Sep 262011 yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

# rpm -ivh yum-*
