Percona Monitoring and Management on Proxmox

  • April 28, 2020December 29, 2020

PMM Server is supplied as a Open Virtualization Format (OVF) appliance file. Proxmox does not directly support the same but we can follow a few steps to make it work ! In my case, I used CEPH rbd storage in proxmox cluster for innstalling PMM. Downlaoded from HERE


SCP the file to Proxmox Host

scp pmm-server-2.5.0.ova root@proxmoxHostIp:/var/lib/vz ssh root@proxmoxHostIp cd /var/lib/vz tar xvf pmm-server-2.5.0.ova ls # PMM2-Server-2020-04-14-1130-disk001.vmdk pmm-server-2.5.0.ova snippets # images PMM2-Server-2020-04-14-1130-disk002.vmdk PMM2-Server-2020-04-14-1130.ovf private # template
Code language: PHP (php)

Convert VMDKs to RAW, the format supported by CEPH RBD storage). Commands to convert to qcow2 format (if you wish to use ZSH) are also listed here

qemu-img convert -f vmdk PMM2-Server-2020-04-14-1130-disk001.vmdk -O raw disk1.raw qemu-img convert -f vmdk PMM2-Server-2020-04-14-1130-disk002.vmdk -O raw disk2.raw qemu-img convert -f vmdk PMM2-Server-2020-04-14-1130-disk001.vmdk -O qcow2 disk001.qcow2 qemu-img convert -f vmdk PMM2-Server-2020-04-14-1130-disk002.vmdk -O qcow2 disk002.qcow2 qm importdisk 126 disk1.raw cephpool1 qm importdisk 126 disk2.raw cephpool1

Create a VM with 2 cores, 4 GB RAM and a HDD in the Proxmox Host. Note the VMID. In my case, VMID was 126. The hard-drives attached to this VM were in a CEPH rbd pool of the proxmox cluster. The name of the pool was cephpool1. Create but do not start the VM.

Now Import the RAW disks to the cephpool1 and associate with the the VMID 126

qm importdisk 126 disk1.raw cephpool1 qm importdisk 126 disk2.raw cephpool1
Code language: CSS (css)

Now these hard drives are imported but not yet enabled for the VM.

Select the VMID > Hardware. You will see two unused disks there. If there are any already attached HDDs, remove and delete them. Then select the first unused (lower numbered) HDD, click Edit > Add in the dialog box. Repeat process for the next unused HDD.

Start up the VM and PMM should start.

Log in using user – root, password – percona and set a new password by followng the prompts.

Set a Static IP address. This is a CentOS 7 VM LINK

vi /etc/cloud/cloud.cfg # ADD LINES network: config: disabled # !wq # IP Address in CIDR notation nmcli con mod "System eth0" ipv4.addresses # Default gateway nmcli con mod "System eth0" ipv4.gateway # DNS nmcli con mod "System eth0" ipv4.dns "" nmcli con mod "System eth0" ipv4.method manual nmcli con mod "System eth0" connection.autoconnect yes sudo reboot
Code language: PHP (php)


ip a # Note the name of ethernet device and edit the corresponding config file vi /etc/sysconfig/network-scripts/ifcfg-eth0
Code language: PHP (php)

Add a user for management and exchange SSH Keys

# On PMM Server adduser vivek passwd vivek usermod -aG wheel vivek yum install nano nano /etc/ssh/sshd_config # Enable PasswordLogin # PasswordAuthentication yes systemctl restart sshd # On Client ssh-copy-id vivek@ # On PMM Server nano /etc/ssh/sshd_config # Disable PasswordLogin # PasswordAuthentication no systemctl restart sshd
Code language: PHP (php)

Set environment

nano /etc/environment # LANG=en_US.utf-8 # LC_ALL=en_US.utf-8 sudo reboot
Code language: PHP (php)

Access web interface and set password

Using a broswer go to the Dashboard at

Log in using admin:admin

set a new password: PMMPassword
