How to Install Remark42 on Fedora Server Latest

Remark42 is an open-source commenting system that can be integrated into any website. It is written in Go and supports multiple databases. In this tutorial, we will show you how to install Remark42 on a Fedora Server Latest.

Prerequisites

  • Fedora Server Latest
  • Root access
  • Nginx or Apache webserver
  • PostgreSQL, MySQL or MariaDB server
  • Git

Step 1: Install Dependencies

Before installing Remark42, we need to install some dependencies.

sudo dnf update && sudo dnf install git golang postgresql-server postgresql-contrib
sudo systemctl enable postgresql
sudo systemctl start postgresql

Step 2: Create a Database

Next, we need to create a database for Remark42. In this example, we will use PostgreSQL.

sudo su - postgres
createdb remark42
createuser remark42user
psql
ALTER USER remark42user WITH ENCRYPTED PASSWORD 'your-strong-password';
GRANT ALL PRIVILEGES ON DATABASE remark42 TO remark42user;
\q
exit

Step 3: Clone Remark42 Repository

We will clone the Remark42 repository using Git.

cd /var/www/
git clone https://github.com/umputun/remark.git

Step 4: Build and Configure Remark42

We will now build and configure Remark42.

cd remark
make
cd bin
./remark migrate --config="../configs/russian.yml"

Next, we need to edit the configuration file. In this example, we will use Nginx.

nano ../configs/nginx-ssl.yml

Uncomment the following lines:

#externalUrl: "http://localhost:8080/"
#tlsCert: "/etc/ssl/certs/localhost.crt"
#tlsKey: "/etc/ssl/private/localhost.key"

Modify the externalUrl with your domain name or IP address.

externalUrl: "https://example.com/"

Save and exit the file.

Step 5: Create Systemd Service

We will now create a systemd service for Remark42.

nano /etc/systemd/system/remark42.service

Add the following lines:

[Unit]
Description=Remark42
After=network.target postgresql.service

[Service]
Type=simple
WorkingDirectory=/var/www/remark/bin/
ExecStart=/var/www/remark/bin/remark serve --config ../configs/nginx-ssl.yml
User=www-data
Group=www-data
LimitNOFILE=4096

[Install]
WantedBy=multi-user.target

Save and exit the file.

Step 6: Start and Enable Remark42

We will now start and enable Remark42.

sudo systemctl enable remark42
sudo systemctl start remark42

Step 7: Configure Firewall

Finally, we need to configure the firewall to allow HTTPS traffic.

sudo firewall-cmd --permanent --zone=public --add-service=https
sudo firewall-cmd --reload

Conclusion

Congratulations! You have successfully installed Remark42 on your Fedora Server Latest. You can now use this commenting system on your website.
