cannot get confluence to run on AWS EC2 Ubuntu 14.04

[kimsia sim]

After I attempted to install the confluence 5.8.6,

I followed mainly the steps in https://confluence.atlassian.com/display/DOC/Installing+Confluence+on+Linux+from+Archive+File#InstallingConfluenceonLinuxfromArchiveFile-2.InstallJava and https://confluence.atlassian.com/display/DOC/Start+Confluence+Automatically+on+Linux

I used `confluence` as user and run `. confluence-start.sh` inside `/usr/local/confluence/current/bin/`

Almost immediately, I get the following message and my user account got switched out of `confluence` and back into `ubuntu`

confluence@ip-xxx.xxx.xxx.xxx:/usr/local/confluence/current/bin$ . start-confluence.sh

To run Confluence in the foreground, start the server with start-confluence.sh -fg
executing as current user
If you encounter issues starting up Confluence, please see the Installation guide at http://confluence.atlassian.com/display/DOC/Confluence+Installation+Guide

confluence@xxx-xxx-xxx-xxx:/home/ubuntu$ cd /usr/local/confluence
confluence@ip-xxx-xxx-xxx-xxx:/usr/local/confluence$ ls -la

I then tried ip address:8090. I get nothing.

Please advise.

**UPDATE**

I have switched to java 8. Same issue

Hi Kimsia, 

Tomcat started.

Your Tomcat looks running fine, so probably your error messages will be on <confluence-data>/logs/atlassian-confluence.log. So, please try the following:

1 - Stop Confluence

2 - Start Confluence

3 - Watch the logs:

tail -f <confluence-data>/logs/atlassian.log

Lastly, can you confirm what are you facing when you try to access Confluence? I mean, is an error message, a blank page?

Regards, 

Renato Rudnicki

Right after I start confluence, the Ubuntu user will suddenly switch from confluence to ubuntu. Not sure if this is intentional. My confluence data is the folder /usr/local/confluence/data. There is nothing inside. Not even a logs folder.

"the Ubuntu user will suddenly switch from confluence to ubuntu" - this is nonsense without the context. Do you mean you are using an account by logging in as another person first and using "exit" to go back to the original? That a process is running and spawns another one running under a different user? Or is the session being forcibly killed by another process you've set up to deliberately kill it? Anyway... If your "cofluence home"/logs is empty, then Confluence is not starting at all. Tomcat is unable to get the application loaded. Have a look at /usr/local/confluence/current/logs/catalina.out - this should have an error message in it to tell you why it can't begin to start Confluence.

Can you confirm if you have setup confluence home variable properly? Please take a look on <confluence-data> confluence/WEB-INF/classes/confluence-init.properties

Nic Brough: without me pressing "exit" it went back to the original (i think) the log file for catalina.out last 2 errors are: # An error report file with more information is saved as: # /usr/local/confluence/atlassian-confluence-5.8.6/bin/hs_err_pid11076.log Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c0000000, 1073741824, 0) failed; error='Cannot allocate memory' (errno=12) # # There is insufficient memory for the Java Runtime Environment to continue. # Native memory allocation (mmap) failed to map 1073741824 bytes for committing reserved memory. # An error report file with more information is saved as: # /usr/local/confluence/atlassian-confluence-5.8.6/bin/hs_err_pid14165.log OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000b5a00000, 1073741824, 0) failed; error='Cannot allocate memory' (errno=12) # # There is insufficient memory for the Java Runtime Environment to continue. # Native memory allocation (malloc) failed to allocate 1073741824 bytes for committing reserved memory. # An error report file with more information is saved as: # /usr/local/confluence/atlassian-confluence-5.8.6/bin/hs_err_pid17813.log

Well, that's pretty clear. You are allocating too much memory to Confluence for your machine. You need to run this on a machine with more memory, or decrease the amount you're giving Confluence (if it's a default installation, then that's not going to work, it's on pretty minimal settings already, and you will definitely need to run this on a machine with more memory)

What does the atlassian-confluence.log file say is going wrong?

[kimsia sim]

where can i find this atlassian-confluence.log?
