shell ssh-copy-id shyt-ceph-mon2
shell ssh-copy-id shyt-ceph-mon3
shell ssh-copy-id shyt-ceph-osd-node1
shell ssh-copy-id shyt-ceph-osd-node2 c) 安装ceph-deploy# 修改本地yum源
shell wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
shell yum clean all
shell yum makecacheshell yum -y install https://mirrors.aliyun.com/ceph/rpm-mimic/el7/noarch/ceph-deploy-1.5.39-0.noarch.rpm
shell ceph-deploy --version
1.5.39 d) 创建部署目录shell mkdir deploy_ceph_cluster cd deploy_ceph_cluster 2. 部署mon/mgr/mds节点 a) 配置主机名shell hostnamectl --static set-hostname shyt-ceph-mon1 b) 修改yum源shell wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
shell wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
shell yum clean all
shell yum makecache c) 创建Ceph Monitor节点在ceph-admin中执行# 生成ceph配置文件、monitor秘钥文件以及部署日志文件。
shell ceph-deploy new shyt-ceph-mon1 shyt-ceph-mon2 shyt-ceph-mon3 d) 在ceph.conf配置中增加以下信息注释版详见附件shell cat /etc/ceph/ceph.conf

--release mimic \
--repo-url http://mirror.tuna.tsinghua.edu.cn/ceph/rpm-mimic/el7/ \
--gpg-url http://mirror.tuna.tsinghua.edu.cn/ceph/keys/release.asc f) 配置初始monitor、并收集所有密钥shell ceph-deploy mon create-initial g) 分发配置文件# 通过ceph-deploy将配置文件以及密钥拷贝至其他节点使得不需要指定mon地址以及用户信息就可以直接管理我们的ceph集群
shell ceph-deploy admin shyt-ceph-mon1 shyt-ceph-mon2 shyt-ceph-mon3 h配置mgr# 运行ceph health打印
# HEALTH_WARN no active mgr
# 自从ceph 12开始manager是必须的应该为每个运行monitor的机器添加一个mgr否则集群处于WARN状态。
shell ceph-deploy mgr create shyt-ceph-mon1:cephsvr-16101 shyt-ceph-mon2:cephsvr-16102 shyt-ceph-mon3:cephsvr-16103# 提示当ceph-mgr发生故障相当于整个ceph集群都会出现严重问题
# 建议在每个mon中都创建独立的ceph-mgr(至少3个ceph mon节点)只需要在每个mon节点参考上面的方法进行创建即可(每个mgr需要不同的独立命名)。 # 关闭ceph-mgr的方式
shell systemctl stop ceph-mgrcephsvr-16101 3. 部署osd节点 a) 配置主机名shell hostnamectl --static set-hostname shyt-ceph-osd-node1 b) 修改yum源shell wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
shell wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
shell yum clean all
shell yum makecache c) 安装ceph软件包shell ceph-deploy install shyt-ceph-osd-node1 shyt-ceph-osd-node2 \
--release mimic \
--repo-url http://mirror.tuna.tsinghua.edu.cn/ceph/rpm-mimic/el7/ \
--gpg-url http://mirror.tuna.tsinghua.edu.cn/ceph/keys/release.asc d) 配置osd节点shell ceph-deploy disk zap shyt-ceph-osd-node1:sdb shyt-ceph-osd-node1:sdc shyt-ceph-osd-node1:sdd
shell ceph-deploy osd create shyt-ceph-osd-node1:sdb shyt-ceph-osd-node1:sdc shyt-ceph-osd-node1:sdd e) 分发配置文件shell ceph-deploy admin shyt-ceph-osd-node1 shyt-ceph-osd-node2# 查看ceph osd节点状态
shell ceph -s
shell ceph osd tree 三、启用Dashboard 在任意节点中执行开启dashboard支持# 启用dashboard插件
shell ceph mgr module enable dashboard
# 生成自签名证书
shell ceph dashboard create-self-signed-cert
Self-signed certificate created
# 配置dashboard监听IP和端口
shell ceph config set mgr mgr/dashboard/server_port 8080
# 配置dashboard认证
shell ceph dashboard set-login-credentials root 123456
Username and password updated
# 关闭SSL支持只用HTTP的方式访问
shell ceph config set mgr mgr/dashboard/ssl false
# 每个mon节点重启dashboard使配置生效
shell systemctl restart ceph-mgr.target
# 浏览器访问 http://10.52.0.181:8080# 查看ceph-mgr服务
shell ceph mgr services
{dashboard: http://shyt-ceph-mon1:8080/
} 四、创建Ceph MDS角色 1. 安装ceph mds # 为防止单点故障需要部署多台MDS节点
shell ceph-deploy mds create shyt-ceph-mon1 shyt-ceph-mon2 shyt-ceph-mon3 2、手动创建data和metadata池 shell ceph osd pool create data 128 128
shell ceph osd pool create metadata 128 128
shell ceph fs new cephfs metadata data
shell ceph mds stat
cephfs-1/1/1 up {0shyt-ceph-mon3up:active}, 2 up:standby 3、挂载cephfs文件系统 shell wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
shell wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
shell cat /etc/yum.repos.d/ceph.repo EOF
