Installing and configuring Search Services with mutual TLS

Use this information to install Alfresco Search Services with mutual TLS.
This task assumes that you're using Alfresco Content Services 6.0.1 with clustering enabled.
Important: Alfresco strongly recommends that you use firewalls and other infrastructure means to ensure that the Search Services server is not accessible from anything other than trusted hosts and/or users, and only on the ports needed for Search Services.
  1. Browse to the Alfresco Support Portal and download
  2. Extract the Search Services distribution to a preferred location.

    See Search Services directory structure for more details.

  3. Set the environment variable, SOLR_PORT:

    If you are using a Windows-based platform, update the alfresco-search-services/ file:

    set SOLR_PORT=8983

    If you are using a Linux-based platform, update the alfresco-search-services/ file:

  4. To secure access to Search Services, you must create a new set of keystores and keys.
    1. Generate secure keys specific to your Alfresco installation.

      For more information, see Generating secure keys overview.

    2. Create a new keystore directory at alfresco-search-services/solrhome.
    3. In the production environment, copy your custom keystore and truststore to the alfresco-search-services/solrhome/keystore directory.
    4. Update the SSL-related system properties.

      If you are using a Windows-based platform, update the alfresco-search-services/ file:

      set SOLR_SSL_KEY_STORE=<SOLR_HOME>\keystore\ssl.repo.client.keystore
      set SOLR_SSL_KEY_STORE_PASSWORD=password
      set SOLR_SSL_TRUST_STORE=<SOLR_HOME>\keystore\ssl.repo.client.truststore

      If you are using a Linux-based platform, update the alfresco-search-services/ file:


      In the above examples, replace <SOLR_HOME> with alfresco-search-services/solrhome, and set your keystore and truststore passwords.

  5. Update the alfresco-search-services/solrhome/conf/ file.

    • If you use several languages across your organization, you must enable cross-language search support in all fields, by adding the following:
  6. (Optional) If you want to install Search Services on a separate machine, check the following before starting Search Services:
    1. Set the environment variable, SOLR_SOLR_HOST, in the following file.




    2. Set the values of environment variables, such as SOLR_ALFRESCO_HOST, in the following file.





      See Search Services externalized configuration.

  7. (Optional) Update the alfresco-search-services/solrhome/conf/ file.

    • Suggestion is disabled by default for Search Services. If you want to enable suggestion, add the following:{}name{}title{}description{}content

    Note: The spell check functionality does not work with Search Services as suggestion is disabled for scalability purpose.
  8. To configure the Solr cores, set the following options:

    • Before creating the alfresco and archive cores:
      • Set alfresco.secureComms=https in alfresco-search-services/solrhome/templates/rerank/conf/
      • Copy the custom keystores to the alfresco-search-services/solrhome/templates/rerank/conf directory.
    • If the alfresco and archive cores already exist, ensure that alfresco.secureComms is set to https for both the cores. For example:
      • alfresco-search-services/solrhome/alfresco/conf/
      • alfresco-search-services/solrhome/archive/conf/
  9. For running a single instance of Search Services (i.e. not sharded), use the following commands:

    cd alfresco-search-services
    ./solr/bin/solr start -a " -Dsolr.ssl.checkPeerName=false -Dcreate.alfresco.defaults=alfresco,archive"
    Note: The -Dcreate.alfresco.defaults=alfresco,archive command automatically creates the alfresco and archive cores. Therefore, you should only start Search Services with -Dcreate.alfresco.defaults=alfresco,archive the first time you are running Search Services.
    Note: To ensure that Search Services connects using IPv6 protocol instead of IPv4, add to the startup parameters.
    Note: You should run this application as a dedicated user. For example, you can create a Solr user.

    The default port used is 8983.

    The command line parameter, -a passes additional JVM parameters, for example, system properties using -D.

    Once Search Services is up and running, you should see a message like:

    Waiting up to 180 seconds to see Solr running on port 8983 [\]  
    Started Solr server on port 8983 (pid=24289). Happy searching!
    To stop all instances of Search Services, use:
    ./solr/bin/solr stop

    The logs are stored in the alfresco-search-services/logs/solr.log file, by default. This can be configured in (for Linux) or (for Windows) using SOLR_LOGS_DIR.

    You have successfully created an alfresco core and an archive core. To verify, in a browser, navigate to the Solr URL, https://localhost:8983/solr. In the Solr Admin UI, select the core selector drop-down list and verify that both the alfresco and archive cores are present in the list.

    Allow a few minutes for Search Services to start indexing.

If you are not using sharded Search Services:
  • Access the Admin Console > Search Service Sharding page.
  • Deselect Dynamic Shard Instance Registration.
  • Select Purge at Startup.
