centos yum設置dag源，安装rrdtool

源码安装rrdtool依赖太多了,很麻煩，下面进行yum 安装rrdtool,首先加入dag的yum.

[root@localhost]# cd /etc/yum.repos.d/
[root@localhost]# vim dag.repo
[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt./redhat/el$releasever/en/$basearch/dag
gpgcheck=1
gpgkey=http://dag./rpm/packages/RPM-GPG-KEY.dag.txt
enabled=1

[root@localhost]# yum install -y rrdtool perl-rrdtool rrdtool-devel
 

这可自动处理依赖，顺利完成安装！
