How to raise JIRA after restart?

Question

PHP

Server on ubuntu x64

Decided to restart JIRA, executed shutdown.sh (the server remained hanging), killed it with the command catholine.sh stop -force
Then launched JIRA, when accessing the browser, it throws me to /secure/SetupDatabase.jspa I

click "next" gives the following "The database specified is not empty. Please specify an empty database for your JIRA installation."

Those. apparently the installation process is starting, but I don’t need to reinstall anything, I just need to start the already installed and configured system again.
