# Deploying SpaceBeans on Debian
This is simple "how to" to deploy the service on a stock Debian installation.
All commands need to be run as `root` user.
(tip: `sudo -i` if you're using sudo)
0. Install OpenJDK JRE headless:
```
apt install openjdk-8-jre-headless
```
(If Java 8 is not available, you can install 11 instead)
1. Create a system user:
```
groupadd spacebeans
adduser --quiet \
--system \
--shell /usr/sbin/nologin \
--home /nonexistent \
--ingroup spacebeans \
--no-create-home \
--disabled-password \
spacebeans
```
2. Copy the server's binary to `/opt/spacebeans/`:
```
mkdir -p /opt/spacebeans
cd /opt/spacebeans
wget https://github.com/reidrac/spacebeans/releases/download/vVERSION/spacebeans-VERSION.jar
```
3. Create a certificate (optional, only if you don't have one already):
```
cd /opt/spacebeans
keytool -genkey -keyalg RSA -alias ALIAS -keystore keystore.jks -storepass SECRET -noprompt -validity 36500 -keysize 2048
chown spacebeans:spacebeans keystore.jks
chmod 0400 keystore.jks
```
When entering the certificate details, use the domain name as `CN`.
In the configuration file provide the path to the keystore, the alias and the
secret used when generating the certificate.
4. Prepare your `spacebeaans.conf` file.
Put it in `/opt/spacebeans/`, with at least one virtual host.
For example:
```
virtual-hosts = [
{
host = "*your domain*"
root = "/var/gemini/*your domain*"
index-file = "index.gmi"
directory-listing = true
key-store {
path = "/opt/spacebeans/keystore.jks"
alias = "*your domain*"
password = "*your secret*"
}
}
]
```
Ensure that the file has the right permissions:
```
cd /opt/spacebeans
chown spacebeans:spacebeans spacebeans.conf
chmod 0400 spacebeans.conf
```
5. Create `/etc/systemd/system/spacebeans.service`:
```
[Unit]
Description=SpaceBeans Gemini Server
After=network.target
[Service]
Type=simple
Restart=always
RestartSec=5
User=spacebeans
ExecStart=/usr/bin/java -jar /opt/spacebeans/spacebeans-VERSION.jar -c /opt/spacebeans/spacebeans.conf
[Install]
WantedBy=multi-user.target
```
Then start the service:
```
systemctl start spacebeans.service
```
Check that it is up and running:
```
systemctl status spacebeans.service
```
(should say "Active: active (running)")
Then enable it so it starts after a reboot:
```
systemctl enable spacebeans.service
```
And you're probably done!
6. Optionally, tidy up your logs.
The logs have redundant information when collected by systemd.
Create this file in `/opt/spacebeans/logback.xml`:
```
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>[%level] %message%n%xException{10}</pattern>
</encoder>
</appender>
<logger name="net.usebox.gemini.server" level="INFO" />
<root level="WARN">
<appender-ref ref="STDOUT" />
</root>
</configuration>
```
Change the `ExecStart` command in your service file to:
```
ExecStart=/usr/bin/java -Dlogback.configurationFile=/opt/spacebeans/logback.xml -jar /opt/spacebeans/spacebeans-VERSION.jar -c /opt/spacebeans/spacebeans.conf
```
This should make the logs nicer.
