The confluence is not well run ?

[Nic Brough -Adaptavist-]

That probably does mean it is not running.  I usually look for "java" though, in case you have not used "confluence" in the path name.

Go to the <install>/bin directory and try running ./start-confluence.sh - that should start it, or give you an error to work with

Hi Nic,

Thanks for your response.

Why do we need to look for "java"?  Bin Installation does not require Java installation, right?   Jave does NOT exist in my virtual machine.

[root@VM_0_16_centos ~]# ps -ef|grep java
root 11973 11835 0 17:03 pts/0 00:00:00 grep --color=auto java
[root@VM_0_16_centos ~]#

Best,

Robert

In term of the install path, I completely use the default setting in the process of installation.    The details are itemized below:

Select the folder where you would like Confluence 7.0.1 to be installed,
then click Next.
Where should Confluence 7.0.1 be installed?
[/opt/atlassian/confluence]

Default location for Confluence data
[/var/atlassian/application-data/confluence]

[xin qiu]

[root@VM_0_16_centos bin]# pwd
/opt/atlassian/confluence/bin

[root@VM_0_16_centos bin]# ./start-confluence.sh

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

Finally got the result from the log,  the memory of virtual machine is NOT enough.  

[Nic Brough -Adaptavist-]

Ah good, yes, you need to run this on a machine which has enough memory to hold the operating system plus the maximum heap size you set for both confluence and synchrony (if you want the collaborative editing)

Thank you!
