3、配置ceph软件仓库
[root@node01 ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
[root@node01 ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
[root@node01 ~]# cat /etc/yum.repos.d/ceph.repo
[ceph]

[root@ceph-node01 ~]# yum update
[root@ceph-node01 ~]# reboot
4、安装ceph-deploy工具
[root@node01 ~]# yum install -y ceph-deploy
5、ceph集群初始化
[root@node01 ~]# mkdir /etc/ceph
[root@node01 ~]# cd /etc/ceph
[root@node01 ceph]#
ImportError: No module named pkg_resources初始化时提示错误，安装yum install -y python2-pip
[root@node01 ceph]# ceph-deploy new node01

6、所有ceph集群节点安装相关软件
[root@node01 ceph]# yum install -y ceph ceph-radosgw [root@node01 ceph]# ceph -v
ceph version 13.2.10 (564bdc4ae87418a232fc901524470e1a0f76d641) mimic (stable)7、客户端安装ceph-common软件
[root@app ~]# yum install -y ceph-common
8、在ceph集群中创建ceph monitor组件
8.1 在配置文件中添加public network配置
[root@node01 ceph]# cat ceph.conf
[global]
fsid = e2010562-0bae-4999-9247-4017f875acc8
mon_initial_members = node01
mon_host = 192.168.140.10
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
public network = 192.168.140.0/24
8.2 在node01节点创建MON服务

8.3 为避免MON的单点故障，在另外两个节点添加MON服务
[root@node01 ceph]# ceph-deploy mon add node02
[root@node01 ceph]# ceph-deploy mon add node03
8.4 查看ceph集群状态
[root@node01 ceph]# ceph -scluster:id: e2010562-0bae-4999-9247-4017f875acc8health: HEALTH_OKservices:mon: 3 daemons, quorum node01,node02,node03mgr: no daemons activeosd: 0 osds: 0 up, 0 indata:pools: 0 pools, 0 pgsobjects: 0 objects, 0 Busage: 0 B used, 0 B / 0 B availpgs:
9、创建mgr服务
ceph自L版本后，添加Ceph Manager Daemon，简称ceph-mgr
该组件的出现主要是为了缓解ceph-monitor的压力，分担了moniotr的工作，例如插件管理等，以更好的管理集群
9.1 在node01节点创建mgr
[root@node01 ceph]# ceph-deploy mgr create node01

9.2 添加多个mgr
[root@node01 ceph]# ceph-deploy mgr create node02

10.3 再次查看集群状态
[root@node01 ceph]# ceph -scluster:id: e2010562-0bae-4999-9247-4017f875acc8health: HEALTH_OKservices:mon: 3 daemons, quorum node01,node02,node03mgr: node01(active), standbys: node02, node03osd: 3 osds: 3 up, 3 indata:pools: 0 pools, 0 pgsobjects: 0 objects, 0 Busage: 3.0 GiB used, 57 GiB / 60 GiB availpgs:
集群扩容的流程(加osd）：
1、准备系统基础环境
2、新节点安装ceph, ceph-radosgw软件
3、同步配置文件到新节点
4、磁盘初始化，添加osd
11、添加dashboard插件
11.1 查看mgr运行的主节点
[root@node01 ceph]# ceph -scluster:id: e2010562-0bae-4999-9247-4017f875acc8health: HEALTH_OKservices:mon: 3 daemons, quorum node01,node02,node03mgr: node01(active), standbys: node02, node03osd: 3 osds: 3 up, 3 indata:pools: 0 pools, 0 pgsobjects: 0 objects, 0 Busage: 3.0 GiB used, 57 GiB / 60 GiB availpgs:
11.2 启用dashboard插件
[root@node01 ceph]# ceph mgr module enable dashboard
11.3 创建dashboard需要的证书
[root@node01 ceph]# ceph dashboard create-self-signed-cert
Self-signed certificate created[root@node01 ceph]# mkdir /etc/mgr-dashboard
[root@node01 ceph]# cd /etc/mgr-dashboard
[root@node01 mgr-dashboard]# openssl req -new -nodes -x509 -subj "/O=IT-ceph/CN=cn" -days 3650 -keyout dashboard.key -out dashboard.crt -extensions v3_ca
Generating a 2048 bit RSA private key
...............................................................................................+++

writing new private key to 'dashboard.key'
-----
[root@node01 mgr-dashboard]#
[root@node01 mgr-dashboard]# ls
dashboard.crt dashboard.key
[root@node01 mgr-dashboard]# 11.4 设置dashboard访问地址
[root@node01 mgr-dashboard]# ceph config set mgr mgr/dashboard/server_addr 192.168.140.10
[root@node01 mgr-dashboard]# ceph config set mgr mgr/dashboard/server_port 8080
[root@node01 mgr-dashboard]#
11.5 重启dashboard插件
[root@node01 mgr-dashboard]# ceph mgr module disable dashboard
[root@node01 mgr-dashboard]# ceph mgr module enable dashboard
11.6 设置用户名、密码
[root@node01 mgr-dashboard]# ceph dashboard set-login-credentials martin redhat
Username and password updated
[root@node01 mgr-dashboard]#
11.7 访问webUI
