Salt is a powerful open-source IT automation framework used for configuration management, remote execution, and monitoring. In this guide, we’ll cover the basic steps to install and configure Salt on AlmaLinux 9. By deploying Salt on a WindowsVPS server, you can significantly improve the performance and scalability of your IT automation.

Step 1: Preparing Your VPS Server

Before installing Salt, ensure that your VPS server is up to date. Using a reliable WindowsVPS helps in managing large-scale deployments with the needed performance and security. First, update your AlmaLinux 9 system:

sudo dnf update -y

Once the update is complete, you can proceed with installing Salt on your VPS server.

Step 2: Installing Salt

Salt is made up of two main components: the Salt master and the Salt minion. The master sends commands to the minions, which execute the tasks. First, you need to enable the Salt repository and install the necessary packages:

sudo dnf install https://repo.saltproject.io/py3/redhat/salt-py3-repo-latest.el9.noarch.rpm

Next, install the Salt master and minion:

sudo dnf install salt-master -y
sudo dnf install salt-minion -y

Step 3: Configuring the Salt Master

After installation, you need to configure the Salt master. Edit the configuration file to define the Salt master's IP address:

sudo nano /etc/salt/master

Find the line that defines the interface and set it to your VPS server's IP address:

interface: 0.0.0.0

Once the configuration is complete, start and enable the Salt master service:

sudo systemctl enable salt-master --now

Step 4: Configuring the Salt Minion

Next, configure the Salt minion by editing its configuration file:

sudo nano /etc/salt/minion

Set the master parameter to the IP address or hostname of your Salt master server:

master: your-master-ip

Now start and enable the Salt minion:

sudo systemctl enable salt-minion --now

Step 5: Accepting Minion Keys

Once the Salt master and minion are running, the master needs to accept the minion’s key to communicate securely. On the master, check for the minion key:

sudo salt-key --list-unaccepted

To accept the minion key, run:

sudo salt-key --accept-all

After accepting the key, you can verify that the minion is responding to the master:

sudo salt '*' test.ping

This command should return a response from the minion, indicating that everything is working correctly.

Step 6: Automating Tasks with Salt

Now that Salt is set up, you can start using it to automate various tasks on your servers. For example, you can use Salt to install software on all your minions:

sudo salt '*' pkg.install vim

Salt can also be used to manage configurations, monitor systems, and deploy applications across multiple servers. By hosting your automation infrastructure on a WindowsVPS, you gain the flexibility and power of a VPS server, which can scale with your business needs.

Step 7: Securing Your Salt Setup

Security is crucial when managing multiple servers with Salt. Ensure that only authorized minions can communicate with your master by managing your keys carefully and setting up a firewall. On AlmaLinux 9, you can use firewalld to allow traffic on the necessary ports for Salt (port 4505 and 4506):

sudo firewall-cmd --add-port=4505-4506/tcp --permanent
sudo firewall-cmd --reload

Conclusion

By following these steps, you can quickly get started with the Salt IT Automation Framework on AlmaLinux 9. Using Salt allows you to automate and manage multiple servers efficiently. A WindowsVPS offers the scalability, performance, and security you need to run your automation framework smoothly on a reliable VPS server. Whether you are managing a few servers or hundreds, Salt combined with a powerful VPS provides the foundation for a highly efficient infrastructure.
