安装ceph客户端
yum -y install ceph ceph-radosgw ntp ntpdate
关闭selinux和firewalld
sed -i 's/SELINUX=.*/SELINUX=disabled/' /etc/selinux/config #重启机器
systemctl stop firewalld
systemctl disable firewalld
同步各个节点时间：
ntpdate -s time-a.nist.gov
echo ntpdate -s time-a.nist.gov >> /etc/rc.d/rc.local
echo "01 01 * * * /usr/sbin/ntpdate -s time-a.nist.gov >> /dev/null 2>&1" >> /etc/crontab
开始部署
在部署节点(mon-1)安装ceph-deploy，下文的部署节点统一指mon-1:
[root@mon-1 ~]# yum -y install ceph-deploy
[root@mon-1 ~]# ceph-deploy --version
1.5.36
[root@mon-1 ~]# ceph -v
ceph version 10.2.3 (ecc23778eb545d8dd55e2e4735b53cc93f92e65b)
在部署节点创建部署目录
[root@mon-1 ~]# mkdir cluster
[root@mon-1 ~]# cd cluster
[root@mon-1 cluster]# ceph-deploy new mon-1 osd-1 osd-2
