Solr 5 - Restrict access to specific IP - solr

Due to security reasons, I wish to restrict access to Solr server to particular IP's only. Since Solr 5 runs as a standalone server, could someone please let me know how can I do this restriction.
I did try searching for a solution, but all I could come up with were solutions related to Solr 4 and previous versions in which Solr war was deployed in containers and not standalone.
Thanks in advance !!!

Unable to contact your Apache Solr server

I have a problem with an old TYPO3 installation (TYPO3 site 7 LTS [7.6.9]).
The site is using Apache Solr as the search engine, but it's not working. When a user tries to search, the system shows a message telling that the search engine is not available now.
In the administration panel, if I go to the Search option, I see this message:
Unable to contact your Apache Solr server.
Hosts missing:http://localhost:8080/solr/core_es/
http://localhost:8080/solr/core_eu/
http://localhost:8080/solr/core_en/
Of course, I have checked that Solr is running and listening on the port 8080. The Solr server is on the same machine than TYPO3.
I found this link about the Apache Solr configuration, but I cannot find these administration pages. I would like to test with the machine's public IP. In fact, I changed all the records regarding Solr in the cf_tx_solr_configuration table, and cleared all the cache tables manually, with no effect.
I have a couple of questions here:
Is it possible to change the configuration of the Solr server in TYPO3? If so, how can I do that?
Is TYPO3 shipped with an out-of-the-box search feature? If so, how can I disable Apache Solr and use the default search engine?
Thanks so much in advance!
please consume appropriate documentation Version of installed Extension.
So I assume(see Version Matix) you are using EXT:Solr version 6.5, therefore you must use the documentation for EXT:Solr v. 6.5.

Is it possible to change the configuration of the Solr server in TYPO3? If so, how can I do that?
Yes, it is. You can set it via TypoScript path "plugin.tx_solr.solr.scheme|host|port|..."
Is TYPO3 shipped with an out-of-the-box search feature? If so, how can I disable Apache Solr and use the default search engine?
Yes, TYPO3 has build in search feature. Its name is indexed_search.
PS: You know, there are much more modern versions of TYPO3 available? Please upgrade at least to the newer major release.

Hoster requirements for running Solr

I am planning to add a full-text search engine for searching a MySQL database to a website. Most recommendations on a nice, user-friendly implementation I found, mentioned the use of Apache Solr.
Keeping this in mind I started searching for the requirements for a hoster to use Solr but I didn't find any useful information expect for "it should support java". So I picked a random host that states it has Java JRE installed (http://wiki.dreamhost.com/What_We_Support) and asked if they supported Solr. Unfortunately, the answer was "no".
So, what would I need to be looking for? Do I need a dedicated server, a VPN, or are there shared hosting solutions where it is possible to run Solr?
What are the system requirements?
I hope there is someone out there, who knows a bit about this. Thanks!
The Solr requirements can be found here: https://wiki.apache.org/solr/SolrInstall
So an installed JRE is needed, but also an servlet container, which also needs an JRE.
If I would be in your situation, I would rent an virtual server.
An other option is an hosting service, specialized for solr hosting: search the web for "apache solr hosting". There are offers for free or payed offers also.
I've been running two drupal websites + apache solr on an ssd vps from rosehosting utilizing 2 cpu cores and 1gb ram. I wasn't able to setup apache solr and java myself so that's why I rented a managed vps service.
If you're not that technical I suggest you add managed to the keywords mentioned by #The Bndr and make sure you check with your host that they will support apache solr and java on your vps

Need some information about Crawl Anywhere and solr

I gone through the crawl anywhere documentation but i am very much confuse about its installation steps.
What i understood is Apache is optional. But do need independent tomcat instance for crawl? Because what i saw in folder structure, there is tomcat folder already present and war file is also there?
Also do we need independent instance of Apache solr also ?
If we want to add postgresql database to crawl, how we can do that?
Please provide some link also so that I can go through it and clarify any doubt I have in my mind.
Apache is needed to use admin interface. Tomcat is needed for some interactive features. You can crawl without both of them.
No.
MySQL and MongoDB are supported. The code is open source, so you can add postgresql support.

Embedded Solr on Amazon AWS

Currently, I have developed a web application. In my web application, I used embedded solr server to make indexing. After that I deployed onto the Tomcat 6 on window xp. Everything is ok. Next, I have tried my web application to deploy on Amazon AWS. My platform is linux + mysql. When I deployed, I got the exception related with embedded solr.
[ WARN] 19:50:55 SolrCore - [] Solr index directory 'solrhome/./data/index' doesn't exist. Creating new index...
[ERROR] 19:50:55 CoreContainer - java.lang.RuntimeException: java.io.IOException: Cannot create directory: /usr/share/tomcat6/solrhome/./data/index
at org.apache.solr.core.SolrCore.initIndex(SolrCore.java:403)
at org.apache.solr.core.SolrCore.<init>(SolrCore.java:552)
at org.apache.solr.core.CoreContainer.create(CoreContainer.java:480)
So how to fix my problem. I am novie to linux.
My guess is that the user you are running Solr under does not have permission to access that directory.
Also, which version of Solr are you using? Looks like 3+. The latest version is 4, so it may make sense to try using that from the start. Probably a bit more troubleshooting to start, but a much better pay off that starting with legacy configuration.
I got solution. That is because of permission affair on Amazon Linux with ec2-user. So , I changed permission by following.
sudo chmod -R ugo+rw /usr/share/tomcat6
http://wiki.apache.org/solr/SolrOnAmazonEC2strong text
t should allow access to ports 22 and 8983 for the IP you're working from, with routing prefix /32 (e.g., 4.2.2.1/32). This will limit access to your current machine. If you want wider access to the instance available to collaborate with others, you can specify that, but make sure you only allow as much access as needed. A Solr instance should not be exposed to general Internet traffic. If you need help figuring out what your IP is, you can always use whatismyip.com. Please note that production security on AWS is a wide ranging topic and is beyond the scope of this tutorial.

Multiple Solr One Application Server (Jboss 7.1)

Is it possibile to have multiple Solrs in the same application server?
If yes, how can I do it?
Im in need of 3 Solr instance and I want them running at the same application server.
Im using Solr 3.6 and Jboss 7.1
Thanks in advance!
It basically depends on what exactly your requirement is.
If your requirement is just to have 3 separate indexes to search upon 3 different modules within a single application, you could probably go with multiple cores in same Solr server.
Refer http://wiki.apache.org/solr/CoreAdmin for more details regarding Solr cores.
If you are planning to host a separate search server for 3 independent applications, then I would suggest you go with 3 Solrs on different ports, as given in above answer.
Yes. You can deploy them on different ports.
http://localhost:8080/solr1
http://localhost:8081/solr2
http://localhost:8082/solr3
and so on.
Check out the instructions from this link http://wiki.apache.org/solr/SolrJBoss
