ceph_deploy部署ceph分布式文件系统

1.前期准备：centos6.5 minimal版本3台

选择其中一台作为一个安装节点,能无密码登录其他机器。ssh-keygen

ssh-keygen -i ~/.ssh/id_rsa.pub node1 node2 node3

2.

命令：

yum install cepy-deploy -y

所有节点安装lsb

yum install lsb -y

关闭防火墙，后面osd服务会向mon服务请求6789端口，防火墙开了访问不了

service iptables stop

创建mon

ceph-deploy new node1 node2 node3

ceph-deploy mon create-initial

创建osd

在所有的osd服务器上执行：

mkdir -p  /var/lib/ceph/osd

mkdir -p /var/lib/ceph/osd

执行命令

ceph-deploy prepare node1:/usr/local/ceph01 node2:/usr/local/ceph02 node3:/usr/local/ceph03

ceph-deploy activate node1:/usr/local/ceph01 node2:/usr/local/ceph03 node3:/usr/local/ceph03

最后执行

ceph -s

如果报错：

ceph-deploy gatherkeys node1

ceph-deploy gatherkeys node2

ceph-deploy gatherkeys node3

如果正常，OK
