## About
[Lemmy](https://github.com/dessalines/lemmy) is similar to sites like [Reddit](https://reddit.com), [Lobste.rs](https://lobste.rs), [Raddle](https://raddle.me), or [Hacker News](https://news.ycombinator.com/): you subscribe to forums you're interested in, post links and discussions, then vote, and comment on them. Behind the scenes, it is very different; anyone can easily run a server, and all these servers are federated (think email), and connected to the same universe, called the [Fediverse](https://en.wikipedia.org/wiki/Fediverse).
For a link aggregator, this means a user registered on one server can subscribe to forums on any other server, and can have discussions with users registered elsewhere.
The overall goal is to create an easily self-hostable, decentralized alternative to reddit and other link aggregators, outside of their corporate control and meddling.
Each lemmy server can set its own moderation policy; appointing site-wide admins, and community moderators to keep out the trolls, and foster a healthy, non-toxic environment where all can feel comfortable contributing.
## Why's it called Lemmy?
- Lead singer from [motorhead](https://invidio.us/watch?v=pWB5JZRGl0U).
- The old school [video game]().
- The [Koopa from Super Mario](https://www.mariowiki.com/Lemmy_Koopa).
- The [furry rodents](http://sunchild.fpwc.org/lemming-the-little-giant-of-the-north/).
Made with [Rust](https://www.rust-lang.org), [Actix](https://actix.rs/), [Inferno](https://www.infernojs.org), [Typescript](https://www.typescriptlang.org/) and [Diesel](http://diesel.rs/).
## Install
### Docker
Make sure you have both docker and docker-compose(>=`1.24.0`) installed.
```bash
mkdir lemmy/
cd lemmy/
wget https://raw.githubusercontent.com/dessalines/lemmy/master/docker/prod/docker-compose.yml
wget https://raw.githubusercontent.com/dessalines/lemmy/master/docker/prod/.env
# Edit the .env if you want custom passwords
docker-compose up -d
```
and goto http://localhost:8536
[A sample nginx config](/docker/prod/nginx.conf), could be setup with:
```bash
wget https://raw.githubusercontent.com/dessalines/lemmy/master/docker/prod/nginx.conf
# Replace the {{ vars }}
sudo mv nginx.conf /etc/nginx/sites-enabled/lemmy.conf
```
### Ansible
First, you need to [install Ansible on your local computer](https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html),
eg using `sudo apt install ansible`, or the equivalent for you platform.
Then run the following commands on your local computer:
```bash
git clone https://github.com/dessalines/lemmy.git
cd lemmy/ansible/
cp inventory.example inventory
nano inventory # enter your server, domain, contact email
ansible-playbook lemmy.yml
```
## Develop
### Docker Development
```bash
git clone https://github.com/dessalines/lemmy
cd lemmy/docker/dev
./docker_update.sh # This builds and runs it, updating for your changes
```
and goto http://localhost:8536
### Local Development
#### Requirements
- [Rust](https://www.rust-lang.org/)
- [Yarn](https://yarnpkg.com/en/)
- [Postgres](https://www.postgresql.org/)
#### Set up Postgres DB
```bash
psql -c "create user lemmy with password 'password' superuser;" -U postgres
psql -c 'create database lemmy with owner lemmy;' -U postgres
export DATABASE_URL=postgres://lemmy:password@localhost:5432/lemmy
```
#### Running
```bash
git clone https://github.com/dessalines/lemmy
cd lemmy
./install.sh
# For live coding, where both the front and back end, automagically reload on any save, do:
# cd ui && yarn start
# cd server && cargo watch -x run
```
