Proxmox VE Cluster memungkinkan untuk melakukan manajemen terpusat dari banyak server fisik. Sebuah Proxmox VE Cluster terdiri dari minimal satu master dan beberapa node (minimal satu master dan satu node).
Fitur Utama
Fitur utama ProxMox VE Cluster adalah
- Manajemen terpusat melalui web.
- satu login dan password untuk mengakses semua node dan guest
- Console dapat melihat semua Virtual Machines
- Melakukan migrasi dari virtual machine antara berbagai mesin yang secara fisik berbeda.
- Sinkronisasi Virtual Appliance template store
Membuat Proxmox VE Cluster
Pertama-tama, instal dua Proxmox VE servers seperti biasa. Pastikan masing-masing Proxmox VE server mempunyai hostname yang unik, karena default-nya semua server akan mempunyai hostname yang sama.
Saat ini, pembuatan cluster hanya dapat dilakukan melalui consol, anda dapat login ke Proxmox VE server melalui ssh.
Semua konfigurasi dapat dilakukan melalui "pveca", PVE Cluster Administration Toolkit
USAGE: pveca -l # memperlihatkan status cluster
pveca -c # membuat cluster baru dengan localhost sebagai master
pveca -s [-h IP] # sync konfigurasi cluster dari master (atau IP)
pveca -d ID # delete node
pveca -a [-h IP] # tambahkan sebuah node baru ke cluster
pveca -m # memaksa local node untuk menjadi master
Mendefinisikan Master
Login melalui ssh ke Proxmox VE server pertama.
Membuat master:
pveca -c
Check status cluster:
pveca -l
Tambahkan node ke master
Login melalui ssh ke Proxmox VE server kedua. Please note, the node should not have any VM´s. (If yes you will get conflicts with identical VMID´s - to workaround, use vzdump to backup and to restore to a different VMID after the cluster configuration).
Join a node to the master:
pveca -a -h IP-ADDRESS-MASTER
To check the state of cluster:
pveca -l
Display the state of cluster:
pveca -l CID----IPADDRESS----ROLE-STATE--------UPTIME---LOAD----MEM---ROOT---DATA 1 : 192.168.7.104 M A 5 days 01:43 0.54 20% 1% 4% 2 : 192.168.7.103 N A 2 days 05:02 0.04 26% 5% 29% 3 : 192.168.7.105 N A 00:13 1.41 22% 3% 15% 4 : 192.168.7.106 N A 00:05 0.54 17% 3% 3%
Working with Proxmox VE Cluster
Now, you can start creating Virtual Machines on Cluster nodes by using the Central Web-based Management on the master.
Troubleshooting
You can manually check the cluster configuration files on each node. Before you edit these files, stop the cluster sync and tunnel service via web interface.
nano /etc/pve/cluster.cfg
Also check if the following file are still up to date, if not because your keys got updated just remove/adapt it.
/root/.ssh/known_hosts
Delete and recreate a cluster configuration
Sometimes it's quicker to delete and recreate your cluster configuration than it is to try and figure out what went wrong. The process includes stoping the cluster sync and tunnel service, deleting the existing cluster config and creating/joining the new cluster. The steps can be found below:
- Note: If your ssh host keys have changed you may need to delete them on each host before you begin:
rm /root/.ssh/known_hosts
- Jot down the IP of the new master node.
- Run on new master node:
/etc/init.d/pvemirror stop /etc/init.d/pvetunnel stop rm /etc/pve/cluster.cfg pveca -c
- Verify that the cluster has been created:
pveca -l
- Run on nodes you wish to add to the new cluster.
- Note: Change IP-ADDRESS-MASTER to the IP of the new master node.
/etc/init.d/pvemirror stop /etc/init.d/pvetunnel stop rm /etc/pve/cluster.cfg pveca -a -h IP-ADDRESS-MASTER
- Verify that the node has been added to the new cluster:
pveca -l
