author: Nic Brough -Adaptavist-
body: 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)


author: xin qiu
body: Finally got the result from the log, the memory of virtual machine is NOT enough.

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>

body: 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?  
\[/opt/atlassian/confluence\]

<br />

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


author: xin qiu
body: 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

body: 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

\[root@VM_0_16_centos qiuxin\]# ps -ef\|grep conflu  

The confluence is not well run ?
