2，持久化卷
- 採用NFS作為後端儲存，NAS、GFS、CEPH同理
- 所有節點
yum install nfs-utils -y2.1 NFS -- > 伺服器：k8s-node01
- 在NFS伺服器上建立es的儲存目錄（使用動態儲存可以自動建立pv，無需此步驟）
[[email protected] es]# pwd
/nfs/es
[[email protected] es]# mkdir es{0..2}
[[email protected] es]# ls
es0 es1 es2- 啟動 nfs
systemctl start rpcbind && systemctl enable rpcbind
systemctl start nfs && systemctl enable nfs- 配置NFS
[[email protected] ~]# more /etc/exports
/nfs/es/ 192.168.2.0/24(rw,sync,no_subtree_check,no_root_squash)- 配置生效
[[email protected] es]# exportfs -rv
exporting 192.168.2.0/24:/nfs/es- 檢視nfs掛載點
[[email protected] es]# showmount -e localhost
Export list for localhost:
/nfs/es 192.168.2.0/24- 測試掛載
[[email protected] ~]#mkdir -p /nfs/es
[[email protected] ~]# mount -t nfs k8s-node01:/nfs/es /nfs/es3，建立叢集
- 使用靜態pv建立es叢集
- 檔案地址：https://github.com/xiaoqshuo/k8s-cluster/tree/master/k8s-efk
- 注：配置了3個pv，只啟了2個例項
