How to Install CloudStack on OpenBSD

In this tutorial, we will go through the steps to install CloudStack on OpenBSD. CloudStack is an open-source cloud computing platform that helps manage a large network of virtual machines.

Prerequisites

• A running instance of OpenBSD
• Root access to the server
• Basic knowledge of the OpenBSD operating system

Step 1: Update the System

Before installing any software, it is important to ensure that the server's software is up-to-date. Run the following command to update the system:

# pkg_add -u

This will update all the packages installed on the system.

Step 2: Install Required Packages

CloudStack requires several packages to be installed on the system, including Java, MySQL, and Tomcat. To install these packages, run the following command:

# pkg_add openjdk mysql-server tomcat

Step 3: Download and Install CloudStack

The next step is to download and install CloudStack. To download CloudStack, go to the official website at http://cloudstack.apache.org/ and download the latest version. In this tutorial, we will be using version 4.12.0.

# curl -O https://downloads.apache.org/cloudstack/4.12.0/apache-cloudstack-4.12.0-src.tar.bz2

Next, extract the downloaded file and change to the extracted directory:

# tar -xvjf apache-cloudstack-4.12.0-src.tar.bz2
# cd apache-cloudstack-4.12.0-src

To build and install CloudStack, run the following command:

# ./install.sh

This will compile the necessary files and install CloudStack on the server.

Step 4: Configure MySQL

After installing CloudStack, you need to configure MySQL to work with CloudStack. First, start the MySQL service:

# rcctl enable mysqld
# rcctl start mysqld

Next, log in to MySQL as the root user:

# mysql -u root

Create a database for CloudStack:

mysql> create database cloud;

Create a new MySQL user and grant it privileges to the cloud database:

mysql> create user 'cloud'@'%' identified by 'password';
mysql> grant all privileges on cloud.* to 'cloud'@'%';
mysql> flush privileges;

Step 5: Configure CloudStack

The final step is to configure CloudStack. Open the global_settings.py file in a text editor:

# vi /usr/local/cloudstack/management/conf/db/global_settings.py

Find the following lines:

db_url = "mysql://root:@localhost/cloud"
db_username = "cloud"
db_password = "password"

Change the root and password values to the values you created in Step 4.

Save and close the file.

Step 6: Start CloudStack

To start CloudStack, start the Tomcat service:

# rcctl enable tomcatd
# rcctl start tomcatd

CloudStack should now be accessible at http://localhost:8080/client.

Conclusion

In this tutorial, we have gone through the steps to install CloudStack on OpenBSD. You should now have a fully functional cloud computing platform to manage virtual machines.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
