How do I start the second node for bamboo datacenter cluster?
Asked by Jonathan Diaz:

Hi I am trying to set up Bamboo Datacenter on a two node cluster for now following these steps:

<https://confluence.atlassian.com/bamboo/installing-bamboo-data-center-1063170560.html>

but when I try to add my other application node it will not start and I can't access it on the web page.

this is a snippet from the catalina.out logs:

Welcome to **Atlassian Community**!

According to the following message:

```
Caused by: java.net.BindException: Address already in use
```

Something is already running and using the port you have configured on \<bamboo-install\>/conf/server.xml.

Please check for any additional copies of Bamboo or other applications that may be using that port and try again.
