I have installed Apache Tomcat 6 and configure Solr 1.4. Now Solr service running successfully.
In Solr 1.4 has two important file solrconfig.xml and schema.xml to configure c# application with Solr service.
But whenver I changed schema.xml file according to sql table’s field it’s stop the Solr service.
so tell me step by step to configure solrconfig.xml and schema.xml
Thanks,
Unfortunately, the question isn't clear or is too broad, so I can only give general advice and point to documentation.
But whenver I changed schema.xml file according to sql table’s field it’s stop the Solr service.
Yes, after changing your schema you either have to restart your Solr instance, or, if you are using Cores (recommended), you have to reload the changed core.
tell me step by step to configure solrconfig.xml and schema.xml
Just change the files according to your needs. The Solr package contains numerous examples, all thoroughly commented. Documentation on solrconfig.xml is here. Documentation on schema.xml is here. After making any change in solrconfig.xml you have to restart your Solr instance.
Also, when making changes to the schema, make sure you reflect those changes in your SolrNet mapping.

We're using Solr 7 and running in production via docker images. I was reading the https://lucene.apache.org/solr/guide/7_4/schema-api.html guide to using the API and trying it to add a new field to an existing schema on a local instance when I got the following error:
{
"responseHeader":{
"status":0,
"QTime":9},
"errors":[{"errorMessages":"schema is not editable"}]}
So I wondered what is the best practice approach for updating a schema on a live system. Is it a case of editing the schema.xml on each node and restarting in turn?
You can either use managed-schema (ManagedIndexSchemaFactory) or classic schema.xml (ClassicIndexSchemaFactory), defined in the solrconfig.xml. The schema.xml doesn't allow change the schema via API. Also if using
ManagedIndexSchemaFactory check if subtag name="mutable" is false, if so the change is disabled. If you are using SolrCloud and recent versions of Solr it is recommended to use managed-schema.
I understand that in Solr 5.0, they provide a REST API to do real-time update of the schema using Curl. However, I could not do that for my eariler version of Solr 4.10.1.
Would like to check, is this function available for the earlier version of Solr, and is the curl syntax the same as Solr 5.0?
According to Solr Wiki, it's possible to request schema from Solr 4.2 and modify it starting from Solr 4.4
In order to enable schema modifications via the Schema REST API, the
schema implementation must be declared as managed by Solr, that is,
not to be manually edited.
Further, the schema must be configured as mutable in order to make
modifications to it.
Both of these schema features (managed and mutable) are configured via
the element in solrconfig.xml.

I am trying to implement solr into sitecore but could not find any way for creating a Solr instance for the same. I have few PDFs from SDN I could find any way to create Solr instance in any. Considering that I am new to CMS I hope I could get some help here. Thank you
There are lots of resources available for setting up Solr, and integrating Sitecore.
Essentially Sitecore is ignorant with respects to how you setup Solr (barring a few exceptions), so you need to follow standard methods to set Solr up. If you are doing this on your local machine, then I recommend you simply download Solr and get it running through the provided Jetty App Server.
Once Solr is running, download the Solr Extensions from SDN, then follow the search scaling guide to integrate Solr. This really only boils down to the following;
Remove Lucene config files
Add Solr config files and binaries
Add Solr endpoint into relevant config
Generate Solr Schema via Sitecore -> Control Panel -> Search (within Sitecore)
Add Schema file to Solr Core configuration
et voila
There is a great guide here: http://www.dansolovay.com/2013/05/setting-up-solr-with-sitecore-7.html
I am going to migrate our app from Lucene 4.7 to Solr 4.7 (in cloud).
As we have some custom analysers I am interested in how complicated is deployment process with Solr Cloud.
Exactly how does it looks like with custom analysers.
I couldn't find any specific information, can anybody help me?
Regards
If you have the jars present on the hosts and inside the solr jvm classpath (or specified in the solr config as presented here : http://svn.apache.org/repos/asf/lucene/dev/trunk/solr/example/solr/collection1/conf/solrconfig.xml) then it should not be harder than specifying the field definitions along with your custom analyzers inside the schema file
how do i change the schema.xml for a collection in SolrCloud?
I have set up a zookeeper-ensemble on 3 nodes and i guess i could make the changes there, but don't know exactly.
You can reload schema.xml for cores on SolrCloud by using zkCli.sh
More details in the Stackoverflow link: Reloading Zoo keeper solr conf (schema.xml)
As of Solr 5.x released, a Schema API was implemented to change the Schema more easily:
https://cwiki.apache.org/confluence/display/solr/Schema+API
The easiest way would be to use 1 node as a bootstrapper, you may add a bootstrap_configdir pointing to your configuration directory. Restarting the service would upload configuration files.
Another option is to use the ZkCli - you can find the usage examples here: http://wiki.apache.org/solr/SolrCloud
