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
