Installing Pomf on Fedora CoreOS

In this tutorial, we will guide you through the installation process of Pomf on your Fedora CoreOS Latest. Pomf is an open-source web application designed to allow users to upload and share files easily. With this tutorial, you will be able to share files effectively on your own instance of Pomf.

Prerequisites

Before we begin, make sure that you have the following prerequisites:

• Fedora CoreOS Latest installed.
• A non-root user account.

Step 1 - Install Required Packages

The first step is to install the necessary packages that Pomf requires to work correctly. Use the following command to install them:

sudo dnf install git wget gcc-c++ make openssl-devel boost-devel mariadb mariadb-server mariadb-devel -y

Step 2 - Clone Pomf Repository

Once the packages are installed, we will clone the Pomf repository from the official GitHub page. Follow these steps to clone it:

1. Move to the "/opt" directory with the following command:

cd /opt

2. Clone Pomf repository using git:

sudo git clone https://github.com/Pomf/Pomf.git

3. Move into the Pomf directory we just cloned:

cd Pomf

Step 3 - Build Pomf

Now, we will build the Pomf application. Follow these steps below:

1. Compile using make:

sudo make

2. Move the build script to /usr/local/bin/pomf:

sudo mv build/pomf /usr/local/bin/

Step 4 - Configure Pomf

For configuration, we will use a sample config file included in the repository.

1. Copy the sample configuration file to a new file:

sudo cp conf/sample.config.json conf/config.json

2. Open the configuration file:

sudo nano conf/config.json

3. In the configuration file, modify the following settings:

{
  "mysql": {
    "host": "127.0.0.1",
    "port": "3306",
    "db": "pomf",
    "user": "root",
    "pass": ""
  },
  "exts": [
    "jpg",
    "jpeg",
    "png",
    "gif",
    "zip",
    "rar",
    "7z",
    "gz",
    "bz2",
    "tar",
    "mp3",
    "mp4",
    "pdf"
  ],
  "listen": {
    "host": "0.0.0.0",
    "port": "5000"
  },
  "upload-path": "/srv/pomf/pomf-files",
  "url-prefix": "https://example.com/files/"
}

4. Here are the changes that you need to make:

• Configure the MariaDB database with the correct details.
• Modify the file extensions that are allowed to be uploaded.
• Set the upload path directory (create this directory before setting it up) and URL Prefix for uploaded files.

Step 5 - Set Up The MariaDB Database

To use Pomf, we need to set up a database. Follow these steps to set up a MariaDB database:

1. Start the MariaDB server:

sudo systemctl start mariadb

2. Secure the database:

sudo mysql_secure_installation

3. Log in to the MySQL console:

sudo mysql -u root -p`

4. Create a new database for Pomf:

CREATE DATABASE pomf;

5. Create a new user for Pomf:

CREATE USER 'pomfuser'@'localhost' IDENTIFIED BY 'pomfpassword';

6. Grant privileges to the new user:

GRANT ALL PRIVILEGES ON pomf.* TO 'pomfuser'@'localhost' IDENTIFIED BY 'pomfpassword';

7. Flush the privileges:

FLUSH PRIVILEGES;

8. Exit MySQL console:

quit

Step 6 - Start Pomf

To start the Pomf application, we need to create a new system unit file in the systemd directory.

1. Open a new file with the "nano" text editor:

sudo nano /etc/systemd/system/pomf.service

2. Paste the following configuration:

[Unit]
Description=Pomf upload site
Documentation=https://github.com/Pomf/Pomf/wiki
Requires=mariadb.service
After=network.target mariadb.service

[Service]
User=pomf
Group=pomf
Type=simple
PIDFile=/run/pomf.pid
ExecStart=/usr/local/bin/pomf -c /opt/Pomf/conf/config.json
GuessMainPID=no
# Don't restart the service if it crashes or is terminated
Restart=on-failure
# Restart the service every 3 hours to keep it fresh
RestartSec=10800s

[Install]
WantedBy=multi-user.target

The above configuration will set up a new unit for the Pomf service. Systemd will use this file to manage the service automatically.

3. Save and exit the text editor:

• Press Ctrl + X, then
• Press "y",
• Then press "Enter".

4. Start the Pomf service.

systemctl start pomf

5. You can verify whether the service has started correctly or not by checking its status:

systemctl status pomf

That's it! You have successfully installed the Pomf file-sharing service on your Fedora CoreOS. You can now use your web browser to access the Pomf service from your server IP address and upload files.
