配置免密登录
[rootnode1 ~]# ssh-keygen -f ~/.ssh/id_rsa -P -q
[rootnode1 ~]# ssh-copy-id node1
[rootnode1 ~]# ssh-copy-id node2
[rootnode1 ~]# ssh-copy-id node3
[rootnode1 ~]# ssh-copy-id node4配置扩展源同时进行部分必需软件安装三个服务器都需要配置
[rootnode1 ~]# wget -O /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo
[rootnode1 ~]# yum install python-pip ansible git -y
[rootnode1 ~]# yum install python-netaddr unzip python36-six.noarch python36-PyYAML.x86_64 ansible -y
[rootnode1 ~]# pip3 install pecan
[rootnode1 ~]# pip3 install werkzeug正式部署ceph集群
以下操作均在node1节点完成
克隆存储库
[rootnode1 ~]# git clone https://github.com/ceph/ceph-ansible.git
[rootnode1 ~]# cd ceph-ansible
[rootnode1 ceph-ansible]# git checkout stable-4.0
修改ansible的hosts主机文件并且进行主机清单添加同时使用以下命令检查判断是否正确。
[rootnode1 ceph-ansible]# vim /etc/ansible/hosts
[rootnode1 ceph-ansible]# ansible-inventory --graph

测试是否可以管理
[rootnode1 ceph-ansible]# ansible all -m ping
node2 | SUCCESS {ansible_facts: {discovered_interpreter_python: /usr/bin/python}, changed: false, ping: pong
}
node4 | SUCCESS {ansible_facts: {discovered_interpreter_python: /usr/bin/python}, changed: false, ping: pong
}
node1 | SUCCESS {ansible_facts: {discovered_interpreter_python: /usr/bin/python}, changed: false, ping: pong
}
node3 | SUCCESS {ansible_facts: {discovered_interpreter_python: /usr/bin/python}, changed: false, ping: pong
}将 ceph-ansible/group_vars/ 下的文件全部备份修改 ceph-ansible/group_vars/all.yml 的配置
[rootnode1 ceph-ansible]# cd group_vars
[rootnode1 group_vars]# for file in *;do cp $file ${file%.*};done修改过的内容如下 [rootnode1 ceph-ansible]# cd group_vars/[rootnode1 group_vars]# vim all.yml

备份 ceph-ansible/site.yml 再修改 ceph-ansible/site.yml 配置 [rootnode1 ceph-ansible]# vim site.yml
---- hosts:- mons - osds- mdss- rgws#- nfss#- rbdmirrors- clients- mgrs#- iscsigws- grafana-server执行启动即可
[rootnode1 ceph-ansible]# ansible-playbook site.yml
健康检查
检查是否部署成功
[rootnode1 ~]# ceph health
HEALTH_WARN mons are allowing insecure global_id reclaim # 该提示部署成功
