Linux server

info

Currently, running Re:Rearth on a serverless platform in the cloud is easier and safer, with less maintenance, and is strongly recommended. The installation method described here should only be performed if you really want to host it on a server that you manage yourself.

This page does not apply if you are using upstart, sysvinit, and so on. We will not explain it here, so please do your own research...

1. Set up a systemd unit file​

  1. Run Re:Earth with an executable binary
  2. Run Re:Earth with docker-compose

1-1. Run Re:Earth with an executable binary​

First, place a binary file of the web server app and front-end files of Re:Earth at anywhere you like.

Check a version and CPU architecture you want to install at GitHub releases

VERSION=0.6.1
ARCH=x86_64
mkidr -p /usr/local/reearth # If you want to run Re:Earth in user mode, ~/reearth is better.
cd $_
curl -Ls https://github.com/reearth/reearth-backend/releases/download/v${VERSION}/reearth-backend_${VERSION}_linux_${ARCH}.tar.gz | tar xvz
curl -Ls https://github.com/reearth/reearth-web/releases/download/v${VERSION}/reearth-web_v${VERSION}.tar.gz | tar xvz
mv reearth-web web

It is OK if the directory structure is as follows:

/usr/local/reearth
├ reearth-backend
└ web
　 ├ index.html
　 └ ...

Then, give permission of the binary file.

chmod a+x reearth-backend

Place a unit file at /lib/systemd/system/reearth.service (root mode) or ~/.config/systemd/user/reearth.service (user mode) as following:

[Unit]
After=network.target

[Service]
ExecStart=/usr/local/reearth/reearth-backend
Restart=always
Type=simple

[Install]
WantedBy=multi-user.target

Next, install MongoDB. See https://www.mongodb.com/docs/manual/installation/.

Next, create a config file at /user/local/reearth/.env. See How to configure Re:Earth.

Then reload systemd:

sudo systemctl daemon-reload

1-2. Run Re:Earth with docker-compose​

First, install Docker.

Next, download Re:Earth's docker-compose.yml at anywhere you like.

mkidr -p /usr/local/reearth # If you want to run Re:Earth in user mode, ~/reearth is better.
cd $_
curl -LOs https://raw.githubusercontent.com/reearth/reearth/main/docker-compose.yml

Next, place a unit file at /lib/systemd/system/reearth.service (root mode) or ~/.config/systemd/user/reearth.service (user mode) as following:

[Unit]
Requires=docker.service

[Service]
Type=simple
ExecStartPre=-/usr/local/bin/docker compose -f ${COMPOSE_FILE} down
ExecStart=/usr/local/bin/docker compose -f ${COMPOSE_FILE} up
ExecStop=/usr/local/bin/docker compose -f ${COMPOSE_FILE} down
Environment=COMPOSE_FILE=/usr/local/reearth/docker-compose.yml

[Install]
WantedBy=multi-user.target

Then reload systemd:

sudo systemctl daemon-reload

2. Start Re:Earth with systemd​

info

If you want to run Re:Earth in user mode, sudo is not required but --user option for systemctl is always required.

Enable and start Re:Earth:

sudo systemctl enable reearth
sudo systemctl start reearth

You can see logs from Re:Earth:

sudo journalctl -u reearth

If you want to stop and disable Re:Earth:

sudo systemctl stop reearth
sudo systemctl disable reearth

3. Set up reverse proxy of your web server​

By default, Re:Earth is delivered on the unprivileged port 8080. The easiest way to make this available to the outside world is to use the reverse proxy function of the web server used in your server beforehand.

3-1. Apache​

info

Someone please write. Or google

3-2. Nginx​

Edit config and then reload Nginx.

The config here are for reference only. Please change them as you see fit to suit your environment.

/etc/nginx/sites-available/reearth.conf
server {
  listen 80;
  server_name reearth.example.com, *.reearth.example.com;

  proxy_http_version                 1.1;
  proxy_set_header Upgrade           $http_upgrade;
  proxy_set_header Connection        "upgrade";
  proxy_set_header Host              $host;
  proxy_set_header X-Real-IP         $remote_addr;
  proxy_set_header X-Forwarded-For   $proxy_add_x_forwarded_for;
  proxy_set_header X-Forwarded-Proto $scheme;
  proxy_set_header X-Forwarded-Host  $host;
  proxy_set_header X-Forwarded-Port  $server_port;

  location / {
    proxy_pass http://127.0.0.1:8080;
  }
}
sudo nginx -t # test nginx config
sudo systemctl reload nginx
curl http://reearth.example.com

4. Set up HTTPS and IDaaS​

ReEarth strongly recommends that you use HTTPS for delivery to protect users' personal information, so please issue a TLS certificate using Let's Encrypt or similar and set it up on your web server.

Also using an IDaaS is recommended instead of Re:Earth build-in authentication server for security in production environments.

I will not explain it here, so please do your own research.
