Apache CloudStack is an open-source cloud computing platform that allows you to deploy and manage large networks of virtual machines. This guide will walk you through the step-by-step installation process on Ubuntu 22.

Prerequisites

  • Ubuntu 22 (with hardware virtualization support)

  • A /24 Network with a gateway ***.***.***.1 and no DHCP to avoid dynamic IP assignment for VMs

Step 1: Update and Upgrade System

sudo apt update && sudo apt upgrade -y

Verify the hostname and network connectivity:

hostname --fqdn
ping 8.8.8.8

Install Chrony for time synchronization:

sudo apt install chrony -y

CloudStack requires Java 17 JRE, which is automatically installed. However, you can configure it beforehand:

sudo apt install openjdk-17-jre -y

Step 2: Add CloudStack Repository

echo "deb https://download.cloudstack.org/ubuntu focal 4.20" | sudo tee /etc/apt/sources.list.d/cloudstack.list

Add the repository key:

wget -O - https://download.cloudstack.org/release.asc | sudo tee /etc/apt/trusted.gpg.d/cloudstack.asc

Update package lists:

sudo apt update

Install CloudStack management server:

sudo apt install cloudstack-management -y

Step 3: Install and Configure MySQL Database

Install MySQL server:

sudo apt install mysql-server -y

Edit the MySQL configuration file:

sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf

Add the following under [mysqld]:

innodb_rollback_on_timeout=1
innodb_lock_wait_timeout=600
max_connections=350
log-bin=mysql-bin
binlog-format = 'ROW'

Restart MySQL service:

sudo systemctl restart mysql

Secure MySQL installation:

sudo mysql_secure_installation

Provide ‘Y’ for all options.

Step 4: Configure SELinux

Check if SELinux is installed:

dpkg -l | grep selinux

Modify the SELinux configuration:

sudo vi /etc/selinux/config

Change:

SELINUX=enforcing

To:

SELINUX=permissive

Apply changes immediately without reboot:

sudo setenforce permissive

Step 5: Set Up CloudStack Database

Use the CloudStack script:

cloudstack-setup-databases cloud:<dbpassword>@localhost --deploy-as=root:<password> -e file -m management_key -k database_key -i <management_server_ip>

Or manually configure MySQL:

CREATE DATABASE cloud;
CREATE DATABASE cloud_usage;
CREATE USER 'cloud'@'localhost' IDENTIFIED BY '<password>';
CREATE USER 'cloud'@'%' IDENTIFIED BY '<password>';
GRANT ALL PRIVILEGES ON cloud.* TO 'cloud'@'localhost';
GRANT ALL PRIVILEGES ON cloud.* TO 'cloud'@'%';
GRANT ALL PRIVILEGES ON cloud_usage.* TO 'cloud'@'localhost';
GRANT ALL PRIVILEGES ON cloud_usage.* TO 'cloud'@'%';
GRANT PROCESS ON *.* TO 'cloud'@'localhost';
GRANT PROCESS ON *.* TO 'cloud'@'%';

Step 6: Configure NFS for Primary and Secondary Storage

Install NFS server:

sudo apt install nfs-kernel-server -y

Create storage directories:

mkdir -p /export/primary
mkdir -p /export/secondary

Edit the NFS exports file:

sudo vi /etc/exports

Add:

/export *(rw,async,no_root_squash,no_subtree_check)

Apply changes:

sudo exportfs -a

Edit NFS configuration:

sudo vi /etc/default/nfs-kernel-server

Uncomment:

LOCKD_TCPPORT=32803
LOCKD_UDPPORT=32769
MOUNTD_PORT=892
RQUOTAD_PORT=875
STATD_PORT=662
STATD_OUTGOING_PORT=2020

Allow ports :

sudo ufw allow from <NETWORK> to any proto udp port 111
sudo ufw allow from <NETWORK> to any proto tcp port 111
sudo ufw allow from <NETWORK> to any proto tcp port 2049
sudo ufw allow from <NETWORK> to any proto tcp port 32803
sudo ufw allow from <NETWORK> to any proto udp port 32769

Restart iptables:

sudo systemctl restart iptables
sudo systemctl save iptables

Step 7: Start CloudStack Services

Restart NFS and enable services:

sudo systemctl start rpcbind
sudo systemctl start nfs-kernel-server
sudo systemctl enable rpcbind
sudo systemctl enable nfs-kernel-server
cloudstack-setup-management

Install KVM

sudo apt update sudo apt install -y qemu-kvm libvirt-clients libvirt-daemon-system bridge-utils virtinst

add your user to libvirt group

sudo usermod -aG libvirt $(whoami) sudo usermod -aG kvm $(whoami)

run

newgrp libvirt

enable kvm

sudo systemctl enable --now libvirtd sudo systemctl start libvirtd

systemctl status libvirtd

verify

sudo virsh list --all

Install CloudStack Agent and UI

Install CloudStack Agent:

sudo apt install cloudstack-agent -y

Install CloudStack UI:

sudo apt install cloudstack-ui -y

Reboot the management server:

sudo reboot

Start CloudStack management service:

sudo systemctl start cloudstack-management

Check service status:

systemctl status cloudstack-management

Open the required port:

sudo ufw allow 8080/tcp

Step 8: Access CloudStack UI

Once everything is set up, access the CloudStack UI via:

http://<Management-Server-IP>:8080/client

Default Credentials:

  • Username: admin

  • Password: password
