Confluence Install fails on RHEL8 with HTTP Status 500
Asked by James:

I'm trying to install Confluence 7.0.2 on RHEL 8 using MSSQL 2017 on Windows Server 2019. The install fails with the error below.

The test database connection is successful. I've assigned this user all permissions (db_owner, db_securityadmin, db_datawriter, db_datareader, etc) on the database I'm using for this. I see a successful login in the logs. I've installed the correct fonts. JRE_HOME is set to /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.222.b10-0.el8_0.x86_64/jre

I installed the package. java-1.8.0-openjdk-devel

I was following this guide

<https://confluence.atlassian.com/doc/installing-confluence-on-linux-143556824.html>

I found a couple of threads with a similar issue but those solutions did not work. I'm lost here. I'm really hoping I don't need to spin up a new VM for RHEL 7. Any ideas?

body: Hi,

can you share more error details from your log?

comments: author: James
body: Hi Petr,

I uploaded the contents of /opt/atlassian/confluence/logs/catalina.2019-10-06.log to Pastebin. I'm getting an error when I try to paste here directly.

<https://pastebin.com/raw/H37nYGr5>

I'd be happy to provide more logs or try something else. I'm stumped at the moment.

body: Did you configure DB by this tutorial?  

<https://confluence.atlassian.com/doc/database-setup-for-sql-server-9258.html>  

Also try to check this troubleshooting article - especially resolution 4

<https://confluence.atlassian.com/confkb/confluence-does-not-start-due-to-spring-application-context-has-not-been-set-218278311.html?_ga=2.34532961.1726001132.1570427201-1758119979.1561550281>  

Let me know


author: James
body: I went through resolutions 1-10 restarting the install after each step and no change.

I decided to do a clean reinstall of Confluence and dropped the MSSQL DB/User I created. I made everything again following that tutorial and I still get a 500 Internal Server Error. This is discouraging. I need a break lol


author: Petr Van??ek
body: Hi,

ok, then I have another advice. Try to install Confluence with PostgreSQL (supported version by supported platforms knowledge base) - if it will work then problem will be somewhere around MS SQL.  

Just try this - then you will be sure where is current problem.
