[tomcat] How to change Apache Tomcat web server port number

How to change Apache Tomcat web server default port number?


I am developing a web application in JSP, in that for some purpose I need to change tomcat accessing port. Is there any possibility?

This question is related to tomcat port

The answer is


Navigate to /tomcat-root/conf folder. Within you will find the server.xml file.

Open the server.xml in your preferred editor. Search the below similar statement (not exactly same as below will differ)

    <Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Going to give the port number to 9090

     <Connector port="9090" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Save the file and restart the server. Now the tomcat will listen at port 9090


You need to edit the Tomcat/conf/server.xml and change the connector port. The connector setting should look something like this:

<Connector port="8080" maxHttpHeaderSize="8192"
           maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionTimeout="20000" disableUploadTimeout="true" />

Just change the connector port from default 8080 to another valid port number.


1) Locate server.xml in {Tomcat installation folder}\ conf \ 2) Find following similar statement

       <!-- Define a non-SSL HTTP/1.1 Connector on port 8180 -->
      <Connector port="8080" maxHttpHeaderSize="8192"
           maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionTimeout="20000" disableUploadTimeout="true" />

For example

<Connector port="8181" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Edit and save the server.xml file. Restart Tomcat. Done
