Trying to uninstall older Jira on CentOs

[Shirley Shorter]

I am trying to uninstall an older Jira before I install the current version since I did not get to use the older version anyway (v7.7.1)

I am not a Linux person by trade. I followed the instructions at https://confluence.atlassian.com/adminjiraserver071/uninstalling-jira-applications-from-linux-802592174.html  and get this:     

  root@server [/opt/atlassian/jira]# ls -a
./ conf/ jre/ NOTICE tomcat-docs/
../ external-source/ lib/ README.html uninstall*
atlassian-jira/ .install4j/ licenses/ README.txt webapps/
bin/ install.reg logs/ temp/ work/
root@server [/opt/atlassian/jira]# uninstall
-bash: uninstall: command not found
   

The uninstall* word in the directory is a bright green for some reason.

@Shirley Shorterif you want to uninstall older version in order to use a new version why not simply upgrading older version to current?

Yes that is possible except I never complered the install so an upgrade might not come out clean

[Shirley Shorter]

I did not use the upgrade method because I used the default database in the installation.
I want my production version to use postgreSQL.
The upgrade only works if you are using the same database.

I followed the advice on another thread about uninstall in Ubuntu (mine is CentOS)
and deleted the installed directories:

sudo service jira stop
rm -rf /opt/atlassian/jira
rm -rf /root/jira
rm -rf /var/atlassian
rm -rf /var/spool/mail/jira

I also deleted a few JIRA web directories in my /home
-->but DO NOT delete the /home/virtfs files!!!

Looking back,
The uninstall did not run for me initially -
I could have tried running with "./uninstall"
(I just typed "uninstall")
If that did not work, I could have tried chmod to give it executable permissions

root@jira-test:/opt/atlassian/jira# uninstall
uninstall: command not found
root@jira-test:/opt/atlassian/jira# ./uninstall
