To ensure a smooth transition from an embedded Solr instance to a standalone one while maintaining data and configuration integrity, follow the steps outlined below:

1. Download Solr and unzip it parrel to ofbiz-framework 
   
   

   Code Block
   / ├── ofbiz-framework/ └── solr-8.11.3/

   
   
   

2. Stop Solr 
   If Solr standalone is running, need to stop.

   Code Block
   ./home/solr8.11.3/bin/solr stop

   
   
   

3. Stop OFBiz
   Before starting, stop the embedded Solr instance to prevent data corruption and file lock issues.
   
   

   Code Block
   cd /home/ofbiz-framework/ ./gradlew terminateOfbiz

   
   
   

4. Copy Core Configuration

   • Navigate to  ${ofbiz.home}/plugins/solr/home/{YourCoreName}  and copy the core configuration. 

   • Paste it into your standalone Solr instance at  solr8.11.3/server/solr/{YourCoreName}. 
     From ofbiz-framework/   

     Code Block
     # Make sure that the {YourCoreName} directory exists in Solr mkdir -p /home/solr8.11.3/server/solr/{YourCoreName}/data/ cp -r plugins/solr/home/{YourCoreName}/* /home/solr8.11.3/server/solr/{YourCoreName}/

     
     
     

5. Copy Data

   • Locate the  <dataDir>  tag in solrconfig.xml to identify the existing data directory. By default, it is  ${ofbiz.home}/runtime/indexes/solr/products/.

   • Copy the contents of the data directory and paste them into  solr8.11.3/server/solr/{YourCoreName}/data/.
     From ofbiz-framework/   

     Code Block
     # Make sure the target data directory exists mkdir -p /home/solr8.11.3/server/solr/{YourCoreName}/data/ # Copy the index data from OFBiz to your standalone Solr core's data directory cp -r runtime/indexes/solr/products/* /home/solr8.11.3/server/solr/{YourCoreName}/data/

     
     
     

6. Update Data Directory

   • Modify  solr8.11.3/server/solr/{YourCoreName}/conf/solrconfig.xml  to set the appropriate data directory path.
     
     

   • To use Solr’s default path, set the following:

     <dataDir>${solr.data.dir:}</dataDir>



   • If you have copied the core data to a custom path, update the path accordingly.
     From ofbiz-framework/ run - 

     Code Block
     sed -i 's|<dataDir>.*</dataDir>|<dataDir>${solr.data.dir:}</dataDir>|' /home/solr8.11.3/server/solr/{YourCoreName}/conf/solrconfig.xml grep "<dataDir>" /home/solr8.11.3/server/solr/{YourCoreName}/conf/solrconfig.xml

     
     
     

7. Start Solr 
   

   Code Block
   cd /home/solr8.11.3bin/solr start
