Stash is now known as Bitbucket Server.
See the

Unknown macro: {spacejump}

of this page, or visit the Bitbucket Server documentation home page.

You may wish to change the port that Stash listens on from the default '7990' to a different value if another application is already running on that port.

To change the port, edit the conf\server.xml file in the <Stash installation directory>.

Find the following lines in server.xml:

<Server port="8006" shutdown="SHUTDOWN">
<Connector port="7990" protocol="HTTP/1.1"

You need to modify both the server port (default is 8006) and the connector port (default is 7990) to ports that are free on your machine. The server port is required by Tomcat but is not user-facing in any way. The connector port is the port you use to access Stash. For example, in the snippet above, the URL would be

(tick)  Hint: You can use netstat to identify free ports on your machine. See more information on using netstat on  Windows  or on  Linux.

(warning) If you are using a firewall, you should ensure that it is configured to allow http/https traffic over the connector port you have chosen. 

(warning) If you are running Stash on a Linix server and want to bind to privileged ports (those below 1024, for example port 80), you will need to start Stash as root in order to successfully bind to the port. Alternatively, you can bind Stash to a port over 1024 and then configure iptables to redirect traffic from port 80 to the higher port.
