Hey there,

We do have a KB article related to the error you're facing:

org.apache.jasper.JasperException: com.atlassian.confluence.tenant.VacantException: Confluence is vacant, a call to tenanted [public abstract net.sf.hibernate.connection.ConnectionProvider

Check it here: https://confluence.atlassian.com/pages/viewpage.action?pageId=779164449

I hope it helps,

Eduardo

Hey There,

I guess something went wrong while setting your database connection. If possible delete your home folder and start the setup once more. 

Or you can also check your database connection into the  confluence.cfg file located in the home folder.

Cheers, 

[Konstantin Abakumov]

Thanks for answer, >>start the setup once more. I have done it several times. I did not set up DP properties, because i'can access web interface for first launch. (There will be asked which db to use) I tried to set up it manually in configuration but it did not hepl Regards, Konstantin.

[Phillip Pham]

where can i find the home folder?

[Guilherme V.]

The home folder path is located inside the confluence-init.properties file. 

To find this file:
<conf_install>/confluence/WEB-INF/classes/ 

[John Harmon]

In my case, mysql was failing to start due to a bad parameter in the my.cnf.  I tracked it down in the /var/log/mysqld.log.  Once I removed the bad parameter(s) mysql started normally and the atlassian products followed.

Just wanted to post that info should anyone else need ideas as to where to look.

[Tom Dickson]

You'd think they could make a simple "UNABLE TO CONNECT TO DATABASE" error, but noooooo.

[Deleted user]

I'm having the same issue on CentOS 6.7 installing 5.8.14.  I had the DNS issue to start but fixed, then uninstalled and re-installed everything (including  dropping/recreating the db).  Not sure what else to try.  I do the install, then browse for the post install.  After choosing the db (MySQL) it appears to go off and do the setup then fails with a blank screen.  catalina.out has:
