Installing Keycloak

Installing Keycloak¶

Hint - active virus scanner

An active virus scanner may slow down the installation.

In a browser, log on to the SEAL Systems delivery platform with your logon data:

Hint - logon data

You receive the logon data from your Technical Project Manager at SEAL Systems.
Download the Keycloak - 26.8.1.162 - rpm folder. It is saved as Keycloak - 26.8.1.162 - rpm.zip.

Extract .zip archive:

unzip "Keycloak - 26.8.1.162 - rpm.zip"

Change to the Keycloak - 26.8.1.162 - rpm directory and start installing the package:
```
cd "Keycloak - 26.8.1.162 - rpm"
```
```
sudo sh install.sh
```
Hint - insufficient java version

If the Java Version is insufficient, the install.sh script stops the installation with an error. Keycloak 22.0 and later versions require at least version 17, see requirements.

Set the JAVA_HOME environment variable when installing Java.
Open the required firewall ports:
```
sudo sh firewall.sh
```
Start the service:
```
sudo systemctl start seal-keycloak
```
Hint - service does not start

If the service does not start, maybe Java cannot be found in the service context. In this case, stop the seal-keycloak service and add the following line to the [Service] section of the /usr/lib/systemd/system/seal-keycloak.service file:
```
[Service]
...
Environment="JAVA_HOME=<java_installation_dir>"
...
```
