centos 7 升级后yum install出现Exiting on user cancel centos 7.x升级后用yum install进行安装时经常出现Exiting on user cancel,例如: [root@localhost ~]# yum install logstash Loaded plugins: axelget, fastestmirror No metadata available for base No metadata available for dock
由于centos的标准组件中是不带rrdtool的,因此我们需要添加一个dag的yum源,以安装rrdtool. 修改/etc/yum.repos.d/CentOS-Base.repo, #vi /etc/yum.repos.d/CentOS-Base.repo 在其末尾追加 [dag] name=Dag RPM Repository for Red Hat Enterprise Linux baseurl=http://apt.sw.be/redhat/el$releasever/en/$ba
