How to configure domain name in tomcat

To configure Tomcat to use a domain name, perform the following steps: Create a server.xml backup. Open server.xml and add the Host element, replacing example.com with your domain name. Create an SSL certificate for the domain name (if required). Add an SSL connector in server.xml, change the port, keystore file, and password. Save server.xml. Restart Tomcat.

Tomcat Configure Domain Name

To configure Tomcat to use a domain name, you need to complete the following steps:

1. Create a backup copy of the server .xml file

Always create a backup copy of the original file before you start modifying the file.

2. Open the server.xml file

usually located in <Tomcat installation directory>/conf.

3. Add the Host element

Inside the <Server> element, add the following XML code snippet:

<code class="xml"><Host name="example.com" appBase="webapps/" unpackWARs="true" autoDeploy="true">
    <Context path="" docBase="ROOT" reloadable="true" />
</Host></code>

• Replace example.com with your domain name.
• appBase Specifies the directory for the web application.
• unpackWARs Specifies whether to unpack WAR files into the appBase directory.
• autoDeploy Specifies whether to automatically deploy new applications found in the appBase directory.
• path Specifies the URL path of the web application.
• docBase Specifies the document root directory of the web application.

4. Create an SSL certificate for your domain name

If you need to use SSL, you must create an SSL certificate for your domain name. For instructions on how to create an SSL certificate, see your certification authority (CA) documentation.

5. Configure the SSL connector

Inside the <Server> element, add the following XML snippet:

<code class="xml"><Connector port="443" protocol="org.apache.coyote.http11.Http11NioProtocol"
           maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
           keystoreFile="path/to/keystore.jks" keystorePass="keystore_password" /></code>

• Change port to the port you want the SSL connector to use. Typically port 443 is used.
• maxThreads Specifies the maximum number of threads that the connector can handle.
• SSLEnabled and scheme enable SSL connections.
• secure Specifies whether the connection uses SSL.
• keystoreFile Specifies the location of the SSL keystore file.
• keystorePass Specifies the password for the keystore file.

6. Save the server.xml file

Save the changes to the server.xml file.

7. Restart Tomcat

Restart Tomcat for the changes to take effect.

After completing these steps, your Tomcat server will be configured to use the provided domain name.
