这是老版本的一个问题，你打开 /etc/yum.repos.d/appnode.repo 文件，内容替换成下面的：
Quote[appnode]
name=AppNode's RPM repository for Enterprise Linux 6 - $basearch
baseurl=http://repo.appnode.com/stable/el/6/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-appnode
[appnode-development]
name=AppNode's RPM repository for Enterprise Linux 6 - $basearch
baseurl=http://repo.appnode.com/development/el/6/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-appnode
[appnode-archive]
