Install SSL in Apache Tomcat

Download and copy your certificate files to your server

Note: When executing the command to import the SSL certificate, you must specify the actual Alias used when you initially created the keystore. If you are unsure of this, run the following command to see the contents of your keystore: keytool -list -keystore mykeystore.jks -v

Configure the keystore

  1. Import a root or intermediate CA certificate to an existing Java keystore. You MUST use the same alias used when the keystore was created, in this case the alias used was mydomain
    • keytool -import -trustcacerts -alias root -file L1root.crt -keystore mykeystore.jks
    • keytool -import -trustcacerts -alias root -file L1Chain.crt -keystore mykeystore.jks
  2. Enter your keystore password. You should get the follow response:
  3. ... is not trusted. Install reply anyway? [no]: yes
  4. Enter 'yes' and hit Enter.
  5. You should get the following response:
  6. Certificate reply was installed in keystore
  7. Import a signed primary certificate to an existing Java keystore
  8. keytool -import -trustcacerts -alias mydomain -file entrustcert.crt -keystore mykeystore.jks

Configure the server

  1. Locate the tomcat config file (default is server.xml), the config filename can be different depending on your Tomcat version or flavour. The config file will need to be updated to reference your keystore file and password.
  2. Open the server.xml file in a text editor (such as vi or notepad)
  3. Find the following section of code in the file (try searching for SSL Connector) and remove the comment tags around the connector entry.
  4. < Connector
        port="8443" minProcessors="5"
        connectionTimeout="60000" debug="0"
        scheme="https" secure="true">
    < Factory
        clientAuth="false" protocol="TLS"
        keystorePass="keystore password here">
    < /Connector>
  5. Save the server.xml file
  6. Restart Tomcat
