Proxmox VE 3.x

TODO

Võrreldes varasema versiooniga on kasutajaliides põhjalikult ümber kirjutatud-disainitud.

• Kõik clustri noded on VÕRDSED. Pole enam master-slave tüüpi clustrit.
• Backup-restore haldusliidesest lihtsam
• haila-vaila (HA)
• kasutajate haldus, võimalik luua erinevate ligipääsuõigustega kasutajaid
• rrdtooliga genereeritud koormusgraafikud iga virtuaalmasina kohta
• Proxmoxi API virtuaalmasinate loomiseks

Cluster

Create the Cluster

Logime üle SSH esimesse clustri nodesse (10.0.0.6) ja anname käsu

# pvecm create YOUR-CLUSTER-NAME

To check the state of cluster:

# pvecm status

Seejärel logime teise clustri nodesse (10.40.0.7) ja anname seal käsu

# pvecm add 10.0.0.6

successfully added node 'jagaja' to cluster.

Kui midagi läks ikkagi viltu siis saab kõigi nodede konfiguratsiooni nullida ära järgmiste käskudega

service cman stop
service pve-cluster stop
rm /etc/cluster/cluster.conf
rm /var/lib/pve-cluster/*
service pve-cluster start
service cman start 

Probleemide korral kontrollida kas /etc/hosts failis on mõlemas masinas info korrektne, on proxmoxi versioon identne ning kellaajad süngis.

• permission denied - invalid ticket (401)

# pvecm updatecerts --force

I guess you need to restart pvedaemon and apache2 (or simply reboot).

How to switch Firefox Java plugin to Sun Java on Ubuntu Linux

Open Synaptic and go to Settings -> Repositories -> Other Software and activate the Canonical partner repo. Now close Synaptic, fire up a terminal and run the following commands in order, selecting Sun Java (java-6-sun) where appropriate:

sudo apt-get update
sudo apt-get install sun-java6-bin sun-java6-fonts sun-java6-jdk sun-java6-plugin
sudo update-alternatives --config java

The tricky part is: even when you have Sun's Java runtime installed, Firefox will still default to the open source IcedTea plugin, unless you tell it not to. Run the following command and select Sun's Java web browser plugin:

sudo update-alternatives --config mozilla-javaplugin.so
