Problem running spring boot with Let's Encrypt certificate on VPS

I want to add an application in Spring Boot services, but I want it to only run as root. When I try to run it as a different user, I have an error:

Failed to start component [Connector[HTTP/1.1-8081]]

org.apache.catalina.LifecycleException: Protocol handler start failed

https://pastecode.xyz/view/2410ddfc

When I run it with sudo it starts correctly.

The application works with the Let's Encrypt certificate, I do not know if it matters.

In my opinion, there is no permission to run Tomcat. :-(

I do not know what to do anymore.

Thank you for your help.

Solution

  • As your stack trace reads, you are not permitted to acces the file:

    /etc/letsencrypt/live/dawid.cloud/keystore.p12 (Permission denied)

    The bottom most caused by statement always is the root cause of an exception.

    If your server shall run as a [user] other than root, which indeed is absolutly a good idea, make this file accessible for that particular [user].

    As a workaround as root:

    mkdir /home/[user]/key
cp -p /etc/letsencrypt/live/dawid.cloud/keystore.p12 /home/[user]/key/
chown -R [user].[user] /home/[user]/key

    Where [user] is your user name.

    I bet there's a more streight forward solution to automate this using the certbot or what ever tool you use to obtain the Let's Encrypt certificate.

    Edit: certbot deploy hook seemes to be a good next search term as pointed out in an answer on superuser.com
