config.sh is not working on Centos 7 Linux with Jira 7.9

[Michael Angelo Timoteo]

Base from the documentation:

https://confluence.atlassian.com/adminjiraserver079/supported-platforms-950288096.html I do not need to install Java on a centos since I will use the linux bundle to install it.

I somehow successfully install it, however, upon executing ./config.sh, I got the following error 

./config.sh
No JRE_HOME or JAVA_HOME environment variable is set - attempting to just run java command
*************************************************************************************************************************************
********** Wrong JVM version! You are running with .. but JIRA requires at least 1.8 to run. **********
*************************************************************************************************************************************

Weird enough, this should not happen because it is already a bundle. 

Is there a way for me to fix this? 

Additionally, when I execute ./version.sh I get the following results:

You need to run java -version and if no return, you need to reboot your server.

If you run java -version and return a version, you need to remove the java that is installed since Jira dont need the server to install it.

@Michael Angelo TimoteoWhat do you wan't to  archive  by running the config  script ?

Hi @Moses Thomas,

I am trying to change port and explore the tool. I finally figure out to make it work; 

1.) Uninstall java that was installed so when you execute java -version it should return null

2.) Restart server

On the changing of ports: there is a manual way to do it but I want to learn and explore the tool.
