分别在dlp节点、node1、node2节点上安装Ceph
[root@dlp ~]# yum -y install yum-utils [root@dlp ~]# yum-config-manager --add-repo https://dl.Fedoraproject.org/pub/epel/7/x86_64/ [root@dlp ~]# yum -y install epel-release --nogpgcheck [root@dlp ~]# cat <<END >>/etc/yum.repos.d/ceph.repo [Ceph] name=Ceph packages for \$basearch baseurl=http://mirrors.163.com/ceph/rpm-jewel/el7/\$basearch enabled=1 gpgcheck=0 type=rpm-md gpgkey=https://mirrors.163.com/ceph/keys/release.asc priority=1 [Ceph-noarch] name=Ceph noarch packages baseurl=http://mirrors.163.com/ceph/rpm-jewel/el7/noarch enabled=1 gpgcheck=0 type=rpm-md gpgkey=https://mirrors.163.com/ceph/keys/release.asc priority=1 [ceph-source] name=Ceph source packages baseurl=http://mirrors.163.com/ceph/rpm-jewel/el7/SRPMS enabled=1 gpgcheck=0 type=rpm-md gpgkey=https://mirrors.163.com/ceph/keys/release.asc priority=1 END
[root@dlp ~]# ls /etc/yum.repos.d/ ##必须保证有默认的官网源，结合epel源和网易的ceph源，才可以进行安装；
