删除默认的源，国外的比较慢
yum clean all
rm -rf /etc/yum.repos.d/*.repo
下载阿里云的base源
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
下载阿里云的epel源
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
修改里面的系统版本为7.3.1611,当前用的centos的版本的的yum源可能已经清空了
sed -i '/aliyuncs/d' /etc/yum.repos.d/CentOS-Base.repo
sed -i '/aliyuncs/d' /etc/yum.repos.d/epel.repo
sed -i 's/$releasever/7.3.1611/g' /etc/yum.repos.d/CentOS-Base.repo
添加ceph源
vim /etc/yum.repos.d/ceph.repo
添加
[ceph]
name=ceph
baseurl=http://mirrors.aliyun.com/ceph/rpm-jewel/el7/x86_64/
gpgcheck=0
[ceph-noarch]
name=cephnoarch
baseurl=http://mirrors.aliyun.com/ceph/rpm-jewel/el7/noarch/
gpgcheck=0
[ceph-source]
name=cephsource
baseurl=http://mirrors.aliyun.com/ceph/rpm-infernalis/el7/SRPMS
gpgcheck=0
[ceph-radosgw]
name=cephradosgw
baseurl=http://mirrors.aliyun.com/ceph/rpm-jewel/el7/x86_64/
gpgcheck=0
进行yum的makecache
yum makecache
安装软件
yum install ceph ceph-deploy
然后我们可以顺利按照官网来安装ceph cluster了
