How to Install Homer on Clear Linux Latest

Homer is an open-source dashboard for your infrastructure, created by Bastien Wirtz. It provides a centralized place to monitor your system metrics, network traffic, application logs, and more. In this tutorial, we will install Homer on Clear Linux Latest using Docker to run the application.

Prerequisites

Before you begin, make sure you have the following:

• Clear Linux Latest installed
• Docker installed and running
• Git installed

Step 1: Clone the Homer repository

First, we need to download Homer from the GitHub repository. Open your terminal and run the following command:

git clone https://github.com/bastienwirtz/homer.git

This will download the entire repository into a new folder called "homer".

Step 2: Configure the environment file

Next, we need to configure the environment file. This file contains information about the database connection, passwords, and other settings for Homer. In the "homer" folder, copy the sample environment file with the following command:

cp .env-example .env

Then, open the ".env" file using a text editor such as Nano:

nano .env

Edit the following lines to match your environment:

APP_URL=http://localhost
APP_URL_PORT=3000
DB_CONNECTION=mysql
DB_HOST=homer_db # this is the name of the Docker container we will create later
DB_PORT=3306
DB_DATABASE=homer
DB_USERNAME=homer
DB_PASSWORD=homerpassword

Make sure to change the passwords and other credentials to match your preferences. Once you are done, save and exit the file.

Step 3: Create the Docker infrastructure

Homer uses several Docker containers to run. We need to create these containers and configure them properly.

a) Create the MySQL container

First, we will create the MySQL container. This container will be used to store the data for Homer.

docker run -d --name homer_db \
-e MYSQL_DATABASE=homer \
-e MYSQL_USER=homer \
-e MYSQL_PASSWORD=homerpassword \
-e MYSQL_ROOT_PASSWORD=rootpassword \
mysql

This command will create a new Docker container with the name "homer_db". The container runs an instance of MySQL with the specified environment variables.

b) Create the Nginx container

Next, we will create the Nginx container. This container will act as a web server for Homer.

docker run -d --name homer_web \
--link homer_db:mysql \
-p 80:80 \
-v `pwd`:/var/www/html \
-v `pwd`/nginx/default.conf:/etc/nginx/conf.d/default.conf \
nginx

This command will create a new Docker container with the name "homer_web". The container runs an instance of Nginx with the specified volume and port mappings.

c) Create the Homer container

Finally, we will create the Homer container. This container will contain the actual Homer dashboard.

docker run -d --name homer \
--link homer_db:mysql \
--link homer_web:nginx \
-v `pwd`/src:/usr/src/app/src \
-v `pwd`/views:/usr/src/app/views \
-v `pwd`/public:/usr/src/app/public \
-v `pwd`/logs:/usr/src/app/logs \
-e NODE_ENV=production \
bastienwirtz/homer:latest

This command will create a new Docker container with the name "homer". The container runs an instance of Homer with the specified volume and environment variables.

Step 4: Access the Homer dashboard

You can now access the Homer dashboard by opening a web browser and navigating to "http://localhost". If everything was configured correctly, you should see the Homer login page.

Login with the default credentials (admin/admin) and you will be redirected to the Homer dashboard. Congratulations, you have successfully installed Homer on Clear Linux Latest!

Conclusion

Homer is a powerful tool for monitoring your infrastructure. By following this tutorial, you have learned how to install it on Clear Linux Latest using Docker. Remember to always configure your environment variables and passwords properly to ensure a secure installation. Happy monitoring!

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!
