安装前准备

#确认安装lvm2
yum install lvm2 -y
#启用rbd模块
modprobe rbd
cat > /etc/rc.sysinit << EOF
#!/bin/bash
for file in /etc/sysconfig/modules/*.modules
do
  [ -x \$file ] && \$file
done
EOF
cat > /etc/sysconfig/modules/rbd.modules << EOF
modprobe rbd
EOF
chmod 755 /etc/sysconfig/modules/rbd.modules
lsmod |grep rbd

克隆文件

$ git clone --single-branch --branch v1.9.2 https://github.com/rook/rook.git
#以上官网的

#我的已经修改好的镜像
  git clone  https://git.rapha.top/admins/rook-ceph.git

修改 operator.yaml 只是简单替换镜像

  ROOK_CSI_CEPH_IMAGE: "registry.cn-hangzhou.aliyuncs.com/qiansong/cephcsi:v3.6.1"
  ROOK_CSI_REGISTRAR_IMAGE: "registry.cn-hangzhou.aliyuncs.com/google_containers/csi-node-driver-registrar:v2.5.0"
  ROOK_CSI_RESIZER_IMAGE: "registry.cn-hangzhou.aliyuncs.com/google_containers/csi-resizer:v1.4.0"
  ROOK_CSI_PROVISIONER_IMAGE: "registry.cn-hangzhou.aliyuncs.com/google_containers/csi-provisioner:v3.1.0"
  ROOK_CSI_SNAPSHOTTER_IMAGE: "registry.cn-hangzhou.aliyuncs.com/google_containers/csi-snapshotter:v5.0.1"
  ROOK_CSI_ATTACHER_IMAGE: "registry.cn-hangzhou.aliyuncs.com/google_containers/csi-attacher:v3.4.0"
  ROOK_CSI_NFS_IMAGE: "registry.cn-hangzhou.aliyuncs.com/google_containers/nfsplugin:v3.1.0"

修改1

在这里插入图片描述

修改2 ROOK_ENABLE_DISCOVERY_DAEMON改成true即可：

在这里插入图片描述

最后部署

kubectl create -f crds.yaml -f common.yaml -f operator.yaml
kubectl -n rook-ceph get pod
kubectl create -f cluster.yaml

在这里插入图片描述

开启配置ceph dashboard 可以看1.83版本的

创建块存储以供 Pod (RWO) 使用

kubectl apply -f storageclass.yaml
# demon
kubectl apply -f pvc.yaml  -f pod.yaml

本次主推文件系统多节点存储

创建文件系统

cat > filesystem.yaml<<END
apiVersion: ceph.rook.io/v1
kind: CephFilesystem
metadata:
  name: myfs
  namespace: rook-ceph
spec:
  metadataPool:
    replicated:
      size: 3
  dataPools:
    - name: replicated
      replicated:
        size: 3
  preserveFilesystemOnDelete: true
  metadataServer:
    activeCount: 1
    activeStandby: true
END

等待mds pod启动，确认文件系统配置完成

# kubectl -n rook-ceph get pod -l app=rook-ceph-mds
