Zookeeper installation* xx.xxx.xxx.100 D:/Stage4/zookeeper/instance1 xx.xxx.xxx.101 D:/Stage4/zookeeper/instance2 and D:/Stage4/zookeeper/instance3 Running ZK on two servers, even if you have three instances, does not give you redundancy. If you lost the .101 server, your ZK would lose quorum, and Solr would become read-only. You must have your three ZK instances on three separate servers in order to have redundancy. http://zookeeper.apache.org/doc/r3.4.12/zookeeperAdmin.html#sc_zkMulitServerSetup If you need assistance moving ZK, consult that project for support resources. From what you have indicated, it doesn't look too challenging, though. *7. Solr installation* There are 2 solr nodes below are the Server IP and its Folder structure xx.xxx.xxx.100 D:/Stage4/solr/ xx.xxx.xxx.101 D:/Stage4/solr/ *8. Edit the file solr.cmd present in /bin folder* Change the value of SOLR_JAVA_MEM from -Xms512m -Xmx512m to –Xms6g –Xmx6g *9. Editing in solr_start.cmd file as per environment specific:* D:\Stage4\Solr\instance2\bin\solr start -f -c -p -z "xx.xxx.xxx.100::xxx7,xx.xxx.xxx.101:xxx8,xx.xxx.xxx.101:xxx9" You don't need the -c option. The presence of the -z option is enough to start in cloud mode. The -c option is only needed if you want to start the embedded ZK server, though it will only start if the -z option is NOT present. Instead of editing solr.cmd to change the heap size, you can add a line to solr.in.cmd: set SOLR_HEAP="6g" Because you are not setting the solr home at all, all you're going to need to do for this move (aside from copying or moving the files) is to stop the existing services, remove the existing services, edit your starting batch file to change the path, and recreate the services. Instead of removing and recreating the services, you could probably edit the registry to modify the services in-place. Thanks, Shawn
Re: Drive Change for existing Solr Setup
Hi Shawn, Thanks for the response. Below are the high level Installation steps used for ZK and Solr setup in Windows* D:\ drive*. Could you please go through once and suggest possible solution/steps needs to be done for the setup moving to the E:\ Drive(New drive) without any impacting to the existing application. We have two cluster servers (IP addresses xx.xxx.xxx.100 and xx.xxx.xxx.101) *1. Zookeeper installation* xx.xxx.xxx.100 D:/Stage4/zookeeper/instance1 xx.xxx.xxx.101 D:/Stage4/zookeeper/instance2 and D:/Stage4/zookeeper/instance3 *2. Example for editing zoo.cfg file as per mentioned like below did for 3 instances.* *tickTime=2000* *initLimit=10syncLimit=5dataDir= D:/Stage /zookeeper/instance1/dataclientPort=server.1= xx.xxx.xxx.101 :xxx7:xxx7server.2= xx.xxx.xxx.101 :xxx8:xxx8server.3= xx.xxx.xxx.101 :xxx9:xxx9**3. Go to the main folder D:/Stage4* a) Right click on folder “zookeeper” -> Properties -> Security -> Edit -> Add -> Add both service accounts b) Under permissions -> give full control c) Click Ok. d) Similarly, add the admin’s name who is working on the set up, and provide full permission to this folder *4. Create zookeeper as a Windows service* a) Create a folder named “nssm” in D: drive. b) Open command prompt and navigate to /nssm-2.24/win64. c) Type the command to create windows service. nssm.exe install Zookeeper_Stage4_instance1 “D:\Stage4\zookeeper\instance1\bin\zkServer.cmd” nssm.exe install Zookeeper_Stage4_instance2 “D:\Stage4\zookeeper\instance2\bin\zkServer.cmd” nssm.exe install Zookeeper_Stage4_instance3 “D:\Stage4\zookeeper\instance3\bin\zkServer.cmd” e) An warning message may appear with text: Administrator access is needed to install a service Press “Yes” in the popup that appears. It will continue and create the service. *5. Go to Windows Start, search “services.msc” and open it. * a) From Services window, select the newly created service and double click on it. b) Service Properties window opens. a. Go to Log on tab. b. Select “Log on as this account” c. Provide the service account name and password d. Click OK. h) Start the service. i) Status should show Running like shown in the below screenshot. *6) Verify if zookeeper is set up correctly.* Go to D:/Stage4/zookeeper/instance Folder named “logs” should be created, with the file zookeeper.log *7. Solr installation* There are 2 solr nodes below are the Server IP and its Folder structure xx.xxx.xxx.100 D:/Stage4/solr/ xx.xxx.xxx.101 D:/Stage4/solr/ *8. Edit the file solr.cmd present in /bin folder* Change the value of SOLR_JAVA_MEM from -Xms512m -Xmx512m to –Xms6g –Xmx6g *9. Editing in solr_start.cmd file as per environment specific:* D:\Stage4\Solr\instance2\bin\solr start -f -c -p -z "xx.xxx.xxx.100::xxx7,xx.xxx.xxx.101:xxx8,xx.xxx.xxx.101:xxx9" *10. Go to the main folder D:/Stage4 * a) Right click on folder “solr” -> Properties -> Security -> Edit -> Add -> Add both service accounts b) Under permissions -> give full control c) Click Ok. d) Similarly, add the admin’s name who is working on the set up, and provide full permission to this folder Create solr as a Windows service a) If “nssm” folder is not present in the machine, then create a folder named “nssm” in D: drive. b) Open command prompt and navigate to /nssm-2.24/win64. c) Type the corresponding commands as in below table 10.240.194.100 nssm.exe install Solr_Stage4_instance1 “D:\Stage4\solr\instance1\bin\solr_start.cmd” 10.240.194.101 nssm.exe install Solr_Stage4_instance2 “D:\Stage4\solr\instance2\bin\ solr_start.cmd” d) A warning message may appear with text: Administrator access is needed to install a service. Press “Yes” in the popup that appears. *11. Go to Windows Start, search “services.msc” and open it. * f) From Services window, select “Solr_Stage4_instance” service and double click on it. g) Service Properties window opens. a. Go to Log on tab. b. Select “Log on as this account” c. Provide the service account name and password d. Click OK. h) Start the service *12. Copy deployment files from file share* *13. Collection creation and validation and 1) Upload config files to zookeeper:* a) Open command prompt and navigate to D:\Stage4\solr\instance2\server\scripts\cloud-scripts b) Then type the following command: zkcli.bat –zkhost “xx.xxx.xxx.100:xxx0,xx.xxx.xxx.101:xxx1,xx.xxx.xxx.101:xxx2” –cmd upconfig –confname en_cache_config –confdir D:/Stage4/PMDM_CacheIndexer/en_cache_config/conf c) Once the upload is done, no success or failure message will be displayed *14. Scheduling indexing tasks* Thanks, Srinivas On Mon, Jun 25, 2018 at 11:34 AM, Shawn Heisey wrote: > On 6/25/2018 1:41 AM, Srinivas Muppu (US) wrote: > >> Is there any possible solution/steps for the moving solr installation >> setup >> from 'E' drive to 'D'-Drive (New Drive) without any impact to the existing >> application(it should not create re indexing again) >> > > You started a previous thread on this topic five

I replied to the list at that time. This time I'm going to include you as a BCC - normally I do not do this, because list membership is usually required to post to the list. Here is the previous reply: - Exactly what needs to be done will be highly dependent on how you installed Solr on your system. The project doesn't have any specific installation steps for Windows, so we have absolutely no idea what you have done. Whoever set up your Solr install is going to know a LOT more about it than we ever can. At a high level, without any information specific to your setup, here's the steps you need: * Stop Solr * Move or copy files to the new location * Change the solr home and possibly other config * Start Solr. - It's very important that you understand that we have absolutely no idea how you've set *anything* up, so we cannot tell you what files need to be changed or where they will be. If you can get in touch with the person who set your Solr up, they should be able to help you make the change that you want to make. Thanks, Shawn
Drive Change for existing Solr Setup
Hi Solr Team, After subscription done with the *solr-user@lucene.apache.org * sending below issue details again to the Solr Mailing list. Please help us as earliest. As part of Solr project installation setup and instances(including clustered solr, zk services and indexing jobs scheduler services) are available in Windows 'E:\ ' drive in production environment. As business needs to remove the E:\ drive, going forward D:\ drive will be used and operational. Is there any possible solution/steps for the moving solr installation setup from 'E' drive to 'D'-Drive (New Drive) without any impact to the existing application(it should not create re indexing again) Please let us know your suggestions if required will create the JIRA ticket for this. Your earliest response will be appreciated!!
