How To Install Cachet Nginx

Overview

Cachet is an open-source monitoring platform that is widely used by web developers, DevOps engineers, and system administrators for monitoring the performance of a wide variety of web applications and services. It can be used for monitoring server performance, application errors, resource usage, and other metrics. This tutorial will guide you through the process of setting up Cachet with Nginx on an Ubuntu 18.04 server.

Prerequisites

Before you begin this guide you’ll need the following:

• A non-root user with sudo privileges
• An Ubuntu 18.04 server
• Nginx installed and configured
• PHP 7.2 or higher installed
• MySQL 5.7 or higher installed
• Cachet Nginx configured

Step 1 – Installing Required Software

We will be installing packages from the default Ubuntu repositories, so update the apt index first and upgrade any existing packages. To do this, run the following command:

sudo apt update

sudo apt upgrade

Next, install the software vendor’s repository key by running the following command:

sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys ACCOF6T1

You will need to add the repository containing the latest version of Cachet. To do this, create a new file in your /etc/apt/sources.list.d directory with the following command:

sudo nano /etc/apt/sources.list.d/cachet.list

Add the following line to the file:

deb https://www.cachet.io/{distribution} {codename} main

Be sure to replace {distribution} and {codename} with the version of Ubuntu you are using. For example, deb https://www.cachet.io/ubuntu bionic main.

Save and close the file when you are finished, then update the apt index and install the Cachet Nginx package with the following command:

sudo apt update

sudo apt install cachet-nginx

When prompted, press Y and then ENTER to confirm the installation.

Step 2 – Configure Cachet Nginx

Once the installation is complete, you will need to configure Cachet Nginx for your domain. To do this, open the configuration file in your text editor with the following command:

sudo nano /etc/cachet-nginx/cachet-config.conf

You will need to change the two variables for the Cachet root and domain. For the root, you will need to enter the root directory of the Cachet installation. This will depend on where you chose to install Cachet. For the domain, you will need to enter the domain name that you wish to use for your Cachet installation. For example:

root /var/www/cachet-nginx

domain example.com

Save and close the file when you are finished, then restart the Nginx web server with the following command:

sudo service nginx restart

Step 3 – Create the MySQL Database

In the next step, you will need to create a new MySQL database for Cachet. To do this, log in to your MySQL shell with the following command:

mysql -u root -p

You will be asked to enter the MySQL root user’s password. Once logged in, create a new database for Cachet with the following command:

CREATE DATABASE cachet;

Next, create a new database user and assign the correct privileges to it with the following commands:

GRANT ALL PRIVILEGES ON cachet.* TO ‘cachetuser’@’localhost’ IDENTIFIED BY ‘password’;

FLUSH PRIVILEGES;

Be sure to replace cachetuser and password with the appropriate database user and password.

Exit the MySQL shell with the following command:

exit

Step 4 – Configure Cachet

Now that the MySQL database has been created and configured, you will need to configure Cachet itself. To do this, open the Cachet configuration file in your text editor with the following command:

sudo nano /etc/cachet-nginx/cachet-config.php

You will need to replace the existing values for the CACHE_DRIVER, SESSION_DRIVER, QUEUE_CONNECTION, and METRIC_DRIVER with the correct values for your system. You will also need to set the values for the following fields:

• DB_HOST – The database host (e.g. localhost)
• DB_USERNAME – The database username (e.g. cachetuser)
• DB_PASSWORD – The database password (e.g. password)
• DB_DATABASE – The name of the database (e.g. cachet)
• APP_URL – The base URL of the application (e.g. http://example.com)

Save and close the file when you are finished.

Step 5 – Install Cachet

At this point, you can install Cachet with the following command:

php artisan cachet:install

You will be asked to enter your database credentials, an administrative email address, and an administrative password. When prompted, press Y and then ENTER to confirm the installation.

Once the installation is complete, you can access the Cachet admin dashboard at http://example.com/admin/. Log in using the administrative email address and password that you provided during the installation.

Step 6 – Testing Cachet

At this point, your Cachet installation is complete and ready to use. To test it out, open your browser and go to http://your-domain-name.com. You should see the Cachet dashboard. Now that you have Cachet up and running, you can begin monitoring your web applications and services.

Conclusion

Congratulations, you have now successfully installed and configured Cachet on your Ubuntu 18.04 server. You can now begin monitoring web applications and services using Cachet. For more information, you can refer to the official Cachet documentation.
