Configuring Solr slave - Configuring Solr slave - Alfresco - Alfresco Search Services - Alfresco/Alfresco-Search-Services/2.0/Alfresco-Search-Services/Configure/Solr-replication/Configuring-the-Alfresco-Content-Services-instance/Configuring-Solr-slave - 2.0 - 2.0

Here again, the solrconfig.xml file controls the configuration affecting replication. To configure the slave server, follow the steps below:

1. Add the following lines to the solrconfig.xml file.

    <requestHandler name="/replication" class="solr.ReplicationHandler" > 
       <lst name="slave">
         <str name="masterUrl">https://solr6master:8983/solr/alfresco</str>
         <str name="pollInterval">00:00:60</str>
       </lst>
    </requestHandler>

   where:

   Parameter name	Description
   pollInterval	Interval in which the slave should poll master .Format is hh:mm:ss. If this is missing, the slave server does not poll automatically.
   masterUrl	Fully qualified URL for the replication handler of master. Make sure the masterUrl ends with <tomcat base url>/solr/alfresco.

2. Set the master URL to point to the Solr master. Also, set how often the slave server should poll for changes.

    <str name="masterUrl">http://your-master-hostname:8983/solr/alfresco</str>
    <str name="pollInterval">00:00:60</str>
   

3. Set the following properties in the solrcore.properties file:

    enable.master=false
    enable.slave=true
   

4. Add the following mTLS client settings to solr.in.sh (Linux) or solr.in.cmd (Windows) files:

   # Slave needs to connect to Master using client mTLS settings
   SOLR_SSL_CLIENT_KEY_STORE: "/opt/alfresco-search-services/keystore/ssl-repo-client.keystore"
   SOLR_SSL_CLIENT_KEY_STORE_PASSWORD: "keystore"
   SOLR_SSL_CLIENT_KEY_STORE_TYPE: "JCEKS"
   SOLR_SSL_CLIENT_TRUST_STORE: "/opt/alfresco-search-services/keystore/ssl-repo-client.truststore"
   SOLR_SSL_CLIENT_TRUST_STORE_PASSWORD: "truststore"
   SOLR_SSL_CLIENT_TRUST_STORE_TYPE: "JCEKS" 

In this configuration, the Solr instance will only track model changes from the Alfresco Content Services platform.
