In order to enable SSL, there are some system properties that you have to turn on. These properties can be found in SOLR_HOME/bin/solr.in.cmd in Windows and SOLR_HOME/bin/solr.in.sh in Unix-based systems.

When you open the file, you will see a set of properties intended for SSL, as highlighted here:

Uncomment the lines:

set SOLR_SSL_ENABLED=true
set SOLR_SSL_KEY_STORE=E:/book/solr/solr-7.2.0/keys/mysolrkeystore.jks
set SOLR_SSL_KEY_STORE_PASSWORD=solrpass
set SOLR_SSL_KEY_STORE_TYPE=JKS
set SOLR_SSL_TRUST_STORE=E:/book/solr/solr-7.2.0/keys/mysolrkeystore.jks
set SOLR_SSL_TRUST_STORE_PASSWORD=solrpass
set SOLR_SSL_TRUST_STORE_TYPE=JKS
set SOLR_SSL_NEED_CLIENT_AUTH=false
set SOLR_SSL_WANT_CLIENT_AUTH=false

Make sure you have changed the keystore path and password as per your configuration.

Once you have done the preceding changes, start Solr using the following command:

solr -p 8984 -Dsolr.ssl.checkPeerName=false

Once the Solr server is up, navigate to the browser and run the following URL:

https://localhost:8984/solr/#/

Since it is a self-signed certificate, you may get a message to accept the certificate and continue. Once you continue, you will see the Solr home page:

In order to check whether the details of the certificate are the same as you created, click on F12 to open developer tools if you are using a Chrome browser:

As shown, click on the Security tab and then on the View Certificate option, which will open a dialog box. Navigate to the Details tab and you will see all the details of the certificate that you have created.
