ceph-mimic版本部署
一、ceph-mimic版本部署
1、环境规划
192.168.140.10 node01 ceph集群节点/ceph-deploy /dev/sdb
192.168.140.11 node02 ceph集群节点 /dev/sdb
192.168.140.12 node03 ceph集群节点 /dev/sdb
192.168.140.13 业务服务器
2、系统基础环境准备
2.1 关闭防火墙、SELinux
2.2 确保所有主机时间同步
[root@node01 ~]# ntpdate 120.25.115.20
14 Jun 11:43:21 ntpdate[1300]: step time server 120.25.115.20 offset -86398.543174 sec
[root@node01 ~]# crontab -l
*/30 * * * * /usr/sbin/ntpdate 120.25.115.20 &> /dev/null
2.3 所有主机ssh免密
[root@node01 ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:I56kRZucE7YCQAOM4RGGOuYuiBj4tgo/1CI9IXqaDEw root@node01
The key's randomart image is:
+---[RSA 2048]----+
|XB. |

|B+ o. @ S |
|*o* .* + . |

+----[SHA256]-----+
[root@node01 ~]# mv /root/.ssh/id_rsa.pub /root/.ssh/authorized_keys
[root@node01 ~]# scp -r /root/.ssh/ root@192.168.140.11:/root/
[root@node01 ~]# scp -r /root/.ssh/ root@192.168.140.12:/root/
[root@node01 ~]# scp -r /root/.ssh/ root@192.168.140.13:/root/
[root@node01 ~]# for i in 10 11 12 13; do ssh root@192.168.140.$i hostname; ssh root@192.168.140.$i date; done

2.4 添加所有主机解析
[root@node01 ~]# cat /etc/hosts

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.140.10 node01
192.168.140.11 node02
192.168.140.12 node03
192.168.140.13 app
[root@node01 ~]# for i in 10 11 12 13
> do
> scp /etc/hosts root@192.168.140.$i:/etc/hosts
> done
hosts 100% 244 411.0KB/s 00:00
hosts 100% 244 51.2KB/s 00:00
hosts 100% 244 58.0KB/s 00:00
hosts 100% 244 58.3KB/s 00:00
[root@node01 ~]#
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]
name=ceph
baseurl=http://mirrors.aliyun.com/ceph/rpm-mimic/el7/x86_64/
enabled=1
gpgcheck=0
priority=1
[ceph-noarch]
name=cephnoarch
baseurl=http://mirrors.aliyun.com/ceph/rpm-mimic/el7/noarch/

enabled=1
gpgcheck=0
priority=1
[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
[root@node01 ceph]# ceph-deploy mon create-initial
[ceph_deploy.conf][DEBUG ] found configuration file at: /root/.cephdeploy.conf
[ceph_deploy.cli][INFO ] Invoked (2.0.1): /usr/bin/ceph-deploy mon create-initial

[root@node02 ~]# ls /etc/ceph/

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 -s

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
[root@node01 ceph]# ceph-deploy mgr create node03
9.3 再次查看集群状态
[root@node01 ceph]# ceph -s
cluster:
id: e2010562-0bae-4999-9247-4017f875acc8
health: HEALTH_WARN

10.3 再次查看集群状态
[root@node01 ceph]# ceph -s
cluster:
id: e2010562-0bae-4999-9247-4017f875acc8
health: HEALTH_OK
services:
mon: 3 daemons, quorum node01,node02,node03
mgr: node01(active), standbys: node02, node03
osd: 3 osds: 3 up, 3 in
data:

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 -s
cluster:
id: e2010562-0bae-4999-9247-4017f875acc8
health: HEALTH_OK
services:
mon: 3 daemons, quorum node01,node02,node03
mgr: node01(active), standbys: node02, node03
osd: 3 osds: 3 up, 3 in
data:
pools: 0 pools, 0 pgs
objects: 0 objects, 0 B
usage: 3.0 GiB used, 57 GiB / 60 GiB avail
pgs:
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
