一、ceph集群搭建准备
二、ceph搭建步骤
三、ceph搭建命令
管理机至各个节点的免密操作
1.1 修改.ssh/config配置文件为
Host ceph-001
Hostname ceph-001
User cephuser
1.2配置文件赋值
chmod 644 ~/.ssh/config
1.3管理节点上生成key
ssh-keygen
1.4将公钥分发至各个节点
此处有多种方式分发
第一种:使用ssh-copy-id命令远程拷贝 ssh-copy-id ceph-002
第二种:scp远程拷贝authorized_keys文件,如果没有该文件就将.ssh/id_rsa.pub的内容复制到该文件中,注意拷贝之后修改目标机器上的该文件权限 chmod 600 authorized_keys
卸载磁盘 umount /data1 ps:卸载12块磁盘并检查type为xfs
创建ceph安装目录,用于存放配置文件
安装ceph,此处使用离线安装

以上为需要安装的rpm,安装是如遇到一下错误
File “/bin/ceph-deploy”, line 18, in
from ceph_deploy.cli import main
File “/usr/lib/python2.7/site-packages/ceph_deploy/cli.py”, line 1, in
import pkg_resources
ImportError: No module named pkg_resources
请执行下面脚本,作用是安装python的包
sudo yum install python-pkg-resources python-setuptools -y
安装过程中可能会遇到很多缺失包和依赖包的错误,切记不可删除系统文件
初始化集群节点 ceph-deploy new ceph-001
修改ceph.conf 此处需要配置网段掩码,否则会造成添加osd节点时错误
public network = xx.xx.xx.x/22 #网段掩码
osd pool default size = 2 #osd副本数量
创建集群 ceph-deploy mon create-initial
将配置同步给各个节点机器 ceph-deploy admin ceph-001 ceph-002
在各个节点上修改权限 sudo chmod 644 /etc/ceph/ceph.client.admin.keyring
创建mgr ceph-deploy mgr create ceph-001
给osd挂载磁盘 ceph-deploy osd create --data /dev/sdb ceph-003
增加2个mon节点,一般要有奇数monitor,但不是必须的。
ceph-deploy mon add ceph-002
ceph-deploy mon add ceph-003
创建对象网关 ceph-deploy rgw create ceph-001
创建账户 sudo radosgw-admin user create --uid=admin --display-name=admin --access_key=admin --secret=123456
创建access秘钥sudo radosgw-admin key create --uid=admin --key-type=s3 --gen-access-key --gen-secret
四、参数及集群节点优化
未完待续
