Installation support - before you can get SERVERID to generate License/SEN

[Jason Fuller]

I'm trying to install Crowd.  There's an error before I can complete the wizard, and hence can't get my ServerID to generate the eval license, and then the SEN - to create a support ticket. 

What to do?

[Nic Brough -Adaptavist-]

Fix the error!  What is it?

[Jason Fuller]

Lol fair enough...  Start script says tomcat started, but netstat shows no port open. Can't localhost:8095.  CentOS7/openjdk1.8/mysql 

(apologies on brevity- on ios atm)

Yeah, phones aren't great for typing

Have a read of the log files, they should tell you what's going wrong.  Start with <crowd data>/logs/atlassian-crowd.log as that should tell you if there are application errors killing it.  Then <crowd install>/apache-tomcat/logs/catalina.out - that's the Tomcat log which will tell you why it can't start the application (there will be an empty or missing atlassian-crowd.log if that's the case)

Hi Nic,

I can't find any log files.

INSTALL DIR is /opt/atlassian/crowd

HOME directory is /var/crowd-home -> it is empty

-rwxr--r--.  1 root root    70 Sep 13 15:35 start_crowd.sh

[root@crowdserver crowd]# ./start_crowd.sh

Tomcat started.
[root@crowdserver crowd]#

SELinux is disabled, firewalld is disabled

I can't find any log created by tomcat - either 'catalina' or 'tomcat' and crowd-home is empty

Ideas?

[Jason Fuller]

Might it be related to a Java problem?  Centos8 comes with OpenJDK1.8 which is on the supported list, and there is a symlink to /etc/aternatives/java in the /usr/bin, so nothing extra in the path needs to be setup.  I did add "export JAVA_HOME=/usr/bin" to the /etc/profile and 

env shows JAVA_HOME correctly.

[Nic Brough -Adaptavist-]

If crowd-home is empty, it's not even starting Crowd, so it must be Tomcat not even getting that far.  Without a catalina.out log file though, I'm stumped - Tomcat always logs something for startup, so I don't know where any output might be going.

I'd be tempted to use brute force - go to the installation and do something like: find -type f -exec grep  -H "Tomcat started" {} \;

That should at least find you the tomcat log.

Hi Nic, thanks for your suggestions. 

Found tomcat log - it was showing this error:

/opt/atlassian/crowd/apache-tomcat/bin/catalina.sh: line 396: /usr/bin/bin/java: No such file or directory

given above that I set the JAVA_HOME to /usr/bin - which is where the symlink is actually at... 

I changed in the /etc/profile to just JAVA_HOME=/usr, and now it works and starts

Is this normal behaviour, to set the JAVA_HOME to the root, and not the actual directory?

[Nic Brough -Adaptavist-]

Java home should set to where java is actually installed.  For example /usr/share/java_1.8_102 - under there, there should be a /bin directory where all the java executables live.  You should be able to work that out by looking at /usr/bin/java* - you should find they are symbolic links to the actual java installation.
