Installing Lemmy on Fedora Server

Lemmy is a decentralized link aggregator that is open-source and privacy-focused. In this tutorial, we will learn how to install Lemmy on Fedora Server, the latest version.

Step 1 – Update the System

We need to make sure the server software packages are up to date before we install Lemmy.

sudo dnf update -y

Step 2 – Install Required Dependencies

Lemmy requires PostgreSQL and Rust to run. We also need to install some other required dependencies to install Lemmy.

sudo dnf install -y gcc-c++ postgresql-server postgresql-devel \
openssl-devel clang cmake pkg-config redis

Step 3 – Install Rust

We can use rustup to install Rust on Fedora Server.

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

After installing Rust, we need to add the following line in .bashrc file.

source $HOME/.cargo/env

Step 4 – Install Lemmy

We can use Git to clone the latest version of Lemmy source code from Github's repository.

git clone https://github.com/LemmyNet/lemmy.git
cd lemmy

With the above command, we must be in the Lemmy directory. Now we can compile and run the software.

RUSTFLAGS='-C target-cpu=native' cargo build --release

In the release folder, we should have a binary named lemmy in location target/release/lemmy.

Next, we can create the configuration file.

cp config-example.toml config.toml

Step 5 – Configure PostgreSQL

We must create a new user and database using the following command.

sudo -u postgres psql -c "CREATE USER lemmy WITH PASSWORD 'password';"
sudo -u postgres psql -c "CREATE DATABASE lemmy OWNER lemmy;"

Lemmy needs to run database migrations to configure the database.

./target/release/lemmy migrate up

Step 6 – Start Lemmy

After completing steps 1 to 5, we can start the Lemmy service.

./target/release/lemmy

We have to navigate to http://localhost:8536 to see the installed Lemmy instance.

Conclusion

In this tutorial, we have learned how to install Lemmy on Fedora Server. If you want to use Lemmy in production, it is recommended to use a web server proxy like Nginx.
