Prerequisites

• Planning your Locator Search SolrCloud setup
• Installing/configuring a Primary Server in a multi-server environment
• Installing/Configuring a Secondary Search Server

Configuration

To configure the secondary server to be an additional web server and Solr Cloud node, follow these steps. 
For version 2.8 and older:Note: in order to add Solr Cloud shards to the secondary server, the current index needs This is a guide to set up SolrCloud on multiple search servers. It's assumed that you have completed configuring the primary server and all secondary search servers, see Prerequisites. You need to have decided on the number of shards for your SolrCloud. This guide will create 6 shards without replication

Note: This guide requires  the current index to be deleted, requiring a re-index of all data.

1. Start by opening Command Prompts in administrator mode on both machines and stop the index service on all machines.
2. Primary: Add new inbound firewall rule. Execute following line in command prompt: 
   netsh advfirewall firewall add rule name="Locator Zookeeper" protocol=TCP localport=9983 action=allow dir=IN profile=domain

3. Primary: Remove all data EXCEPT "configsets" from ProgramData\ayfie\Locator\Solr
   
4. Primary: Remove all data from ProgramData\ayfie\Locator\ZooKeeper
   
5. Secondary: In Program Files\afyie\Locator\SOLR\bin\Solr.in.cmd replace line "REM set ZK_HOST=" with "set ZK_HOST=<<Primary_IPv4_Address>>:9983". On Locator upgrades this will be loaded from the Secondary's DataAccess.config
   
6. Secondary: Add new inbound firewall rule. Execute following line in command prompt: 
   netsh advfirewall firewall add rule name="Locator index admin dashboard" protocol=TCP localport=8983 remoteip=<<Primary_IPv4_Address>> action=allow dir=IN profile=domain

7. Secondary: Remove all data from ProgramData\ayfie\Locator\Solr. The config sets will now be loaded from ZooKeeper on the primary.
   
8. Secondary: Remove folder ProgramData\ayfie\Locator\ZooKeeper
   
9. Primary: Start the index service and upload the config with the command: (In Program Files\ayfie\Locator\SOLR\bin)
   solr zk upconfig -z localhost:9983 -n ViaWorksCloud -d C:\ProgramData\ayfie\Locator\Solr\configsets\ViaWorksCloud\conf
   
10. Secondary: Start index service
    
11. Primary: Run the command (this will create 6 shards divided on the two servers WITHOUT replication) (In Program Files\ayfie\Locator\SOLR\bin)
    solr create -c ViaWorksCloud -d "C:\ProgramData\ayfie\Locator\Solr\ViaWorksCloud" -shards 6 -replicationFactor 1 -p 8983
    
12. Primary: Verify that logs are OK (Go to http://localhost:8983/solr/#/~logging) and the SOLR dashboard now shows 6 shards (http://localhost:8983/solr/#/~cloud)
    
13. Primary: Reindex all data using the Via.repository tool and monitor the reindexing.

For Locator 2.9 and newer:

Note: in order to add Solr Cloud shards to the secondary server, the current index needs to be deleted, requiring a re-index of all data.

1. Start by opening Command Prompts in administrator mode on both machines and stop the index service on all machines.
2. Primary: Add new inbound firewall rule. Execute following line in command prompt: 
   netsh advfirewall firewall add rule name="Locator Zookeeper" protocol=TCP localport=9983 action=allow dir=IN profile=domain

3. Primary: Remove all data EXCEPT "configsets" from ProgramData\ayfie\Locator\Solr
   
4. Primary: Remove all data from ProgramData\ayfie\Locator\ZooKeeper
   
5. Secondary: In Program Files\ayfie\Locator\SOLR\bin\Solr.in.cmd replace line "REM set ZK_HOST=" with "set ZK_HOST=<<Primary_IPv4_Address>>:9983". On Locator upgrades this will be loaded from the Secondary's DataAccess.config
   
6. Secondary: Add new inbound firewall rule. Execute following line in command prompt: 
   netsh advfirewall firewall add rule name="Locator index admin dashboard" protocol=TCP localport=8983 remoteip=<<Primary_IPv4_Address>> action=allow dir=IN profile=domain

7. Secondary: Remove all data from ProgramData\ayfie\Locator\Solr. The config sets will now be loaded from ZooKeeper on the primary.
   
8. Secondary: Remove folder ProgramData\ayfie\Locator\ZooKeeper
   
9. Primary: Start the index service and upload the config with the command: (In Program Files\ayfie\Locator\SOLR\bin)
   solr zk upconfig -z localhost:9983 -n ViaWorksCloud -d C:\ProgramData\ayfie\Locator\Solr\configsets\ViaWorksCloud\conf
   
10. Secondary: Start index service
    
11. Primary: ~collections/ViaWorksCloud
12. Delete the ViaWorksCloud collection, by clicking Delete and confirming the deletion.
