Simple !!... you can do it easily via server.xml

Go to tomcat>conf folder
Edit server.xml
Search "Connector port"
Replace "8080" by your port number
Restart tomcat server.

You are done!.

In windows usually, the tomcat config folder is located at "C:\Program Files\Apache Software Foundation\Tomcat 9.0\conf" – Marwan Salim Nov 06 '18 at 04:48
If I change to 8081, it works perfectly, but if i change to 80, it did not work at all. Googled a few solutions, no one worked, any idea? I am using Apache 9 & Ubuntu 18. Thanks – Charlie Dec 26 '19 at 01:20

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.

i got the answer, thanks for your time. – Siva Siva Aug 24 '13 at 06:19 — Siva Siva, Aug 24 '13 at 06:19

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
