执行yum install时，终端一直刷重复的内容

执行yum install时，终端一直刷重复的内容，看起来不像报错，可是又无休止的刷

起因

启动nginx报错，说找不到libcrypto.so.6
这是因为缺少openssl相关包
于是执行下载 yum install openssl*

发现同步了一些库后，开始重复的刷如下内容：

—> Package hal.x86_64 0:0.5.14-11.el6 will be obsoleted
–> Processing Dependency: hal >= 0.5.10 for package: hal-info-20090716-3.1.el6.noarch

原因

这是centos6和centos7的yum源混用了导致的

处理

首先配置yum源
yum源配置参考：

(如果wget报错 可以尝试手动打开后面的链接查看yum源配置 复制到本机的/etc/yum.repos.d/CentOS-Base.repo)
#yum clean all
#yum makecache
