Cachet is an open-source status page system that allows you to monitor the availability and performance of your applications, services, and infrastructure. It is built on top of the PHP programming language and the MySQL database, and it has a user-friendly interface and a variety of powerful features. In this article, we will show you how to install Cachet on Rocky Linux 8.

• Before you can install Cachet, you need to make sure that your Rocky Linux 8 system is up to date. Run the following command to update the package index:

sudo dnf update

• Next, you need to install the required dependencies for Cachet. This includes the Apache web server, the PHP programming language, and the MySQL database server. To install these dependencies, run the following command:

sudo dnf install httpd php mysql-server 

• After installing the dependencies, start the Apache web server and the MySQL server, and enable them to start at boot time by running the following commands:

sudo systemctl start httpd
sudo systemctl enable httpd
sudo systemctl start mysqld
sudo systemctl enable mysqld

• With the web server and database server running, you can download the latest version of Cachet from the official website. To do this, open a web browser and navigate to https://cachethq.io/. This will bring up the Cachet website, where you can download the Cachet installation package.
• Once the download is complete, extract the downloaded file to the /var/www/html directory. This directory is the default document root for the Apache web server, and it is where Cachet will be installed. To extract the file, run the following commands:

cd /var/www/html
unzip cachet*.zip

This will extract the contents of the downloaded file to the /var/www/html directory.

• After extracting the files, you need to create a database for Cachet. To do this, log in to the MySQL server as the root user by running the following command:

mysql -u root -p

This will prompt you for the password for the root user. Enter the password, and press Enter to log in to the MySQL server.

• Once you are logged in, run the following SQL commands to create a database named cachet and a user named cachet with the password cachet:

CREATE DATABASE cachet;
CREATE USER 'cachet'@'localhost' IDENTIFIED BY 'cachet';
GRANT ALL PRIVILEGES ON cachet.* TO 'cachet '@'localhost';

• After creating the database and user, exit the MySQL prompt by running the exit command.
• Next, you need to configure Cachet to connect to the database that you just created. To do this, open the .env file in the /var/www/html/cachet directory in a text editor. This file contains the environment variables that Cachet uses to configure its various settings.
• In the .env file, find the DB_DATABASE variable, and set its value to cachet. This tells Cachet to use the cachet database for storing its data.
• Find the DB_USERNAME variable, and set its value to cachet. This tells Cachet to use the cachet user to connect to the database.
• Find the DB_PASSWORD variable, and set its value to cachet. This specifies the password for the cachet user.
• Save the .env file, and close the text editor.
• With the database configured, you can now run the Cachet installation script. To do this, open a web browser and navigate to http://localhost/cachet/. This will bring up the Cachet installation page, where you can enter the details for your Cachet installation.
• On the installation page, enter the details for the Cachet administrator user account. This includes the username, password, and email address for the administrator user. Once you have entered the details, click the “Install Cachet” button to start the installation process.
• Once the installation is complete, click the “Login” button to log in to your Cachet account using the administrator username and password that you specified earlier.

Congratulations! You have successfully installed Cachet on Rocky Linux 8 and set up your Cachet administrator account. You can now start using Cachet to monitor the availability and performance of your applications, services, and infrastructure.
