How to allow a master server to access es over HTTP?
Jay also added an important point - if you're using a firewall, remember to add a rule allowing traffic to that port. If you want to allow a master server to access ES over http, then add a rule allowing access to only from that particular address. For example, say you are using ufw, then run this command to add your port:
How do I access Elasticsearch remotely?

How do I connect to an Elasticsearch server?
There are two ways to connect to your Elasticsearch cluster: Through the RESTful API or through the Java transport client. Both ways use an endpoint URL that includes a port, such as https://ec47fc4d2c53414e1307e85726d4b9bb.us-east-1.aws.found.io:9243 .
How do you expose Elasticsearch?
You need to include network. host:0.0. 0.0 in your elasticsearch. yml file so that it listens on the non-loopback address and after that, if your app-server and ES are both in the same VPC, app-server will be able to connect to ES(provided if you exposed 9200 port in security group(in case of AWS).

Create an entry in your SSH config file ( ~/.ssh/config on a Mac): ... Run ssh estunnel -N from the command line.localhost:9200 should now be forwarded to your secure Elasticsearch cluster.
How do I know if Elasticsearch is reachable?
Verify elasticsearch is running by typing $ smarts/bin/sm_service show. 2. Verify elasticsearch is serving requests from a browser on the same machine in Windows or using a tool like curl on Linux. A page specific to the browser will appear.
Is it safe to expose Elasticsearch?
Whatever you do, never expose your cluster nodes to the web . This sounds obvious, but evidently this isn't done by all. Your cluster should never-ever be exposed to the public web .
How do I access Kibana remotely?

How do I run Elasticsearch on localhost?
On a mac, double-click on the file to unzip it. In your terminal, go to the folder that contains Kibana, and run this command. Now, head to the following link in your browser : http://localhost:5601. We now have both Kibana and Elasticsearch running!
Can Elasticsearch be used as a primary database?
Now, is it still possible to use ElasticSearch as a database ? Yes, on the following cases: Event sourcing on the database end. That means, a message queue or event streaming system such as Kafka front the ElasticSearch indexing.
Why use Elasticsearch instead of SQL?
You want Elasticsearch when you're doing a lot of text search, where traditional RDBMS databases are not performing really well (poor configuration, acts as a black-box, poor performance). Elasticsearch is highly customizable, extendable through plugins. You can build robust search without much knowledge quite fast.
Is Elasticsearch a relational database?
Because Elasticsearch is not a relational database, joins do not exist as a native functionality like in an SQL database. It focuses more on search efficiency as opposed to storage efficiency. The stored data is practically flattened out or denormalized to drive fast search use cases.
How do I find my Elasticsearch URL?

What is the default username and password for Elasticsearch?
The default Elasticsearch installation contains a few users, including an admin user with the password elasticadmin.
What ports does Elasticsearch use?
By default, Elasticsearch will use port 9200 for requests and port 9300 for communication between nodes within the cluster.
Connect to remote clusters edit
Your local cluster uses the transport interface to establish communication with remote clusters. The coordinating nodes in the local cluster establish long-lived TCP connections with specific nodes in the remote cluster. Elasticsearch requires these connections to remain open, even if the connections are idle for an extended period.
Dynamically configure remote clusters edit
Use the cluster update settings API to dynamically configure remote settings on every node in the cluster. The following request adds three remote clusters: cluster_one, cluster_two, and cluster_three.
Statically configure remote clusters edit
If you specify settings in elasticsearch.yml, only the nodes with those settings can connect to the remote cluster and serve remote cluster requests.
Remote clusters edit
You can connect a local cluster to other Elasticsearch clusters, known as remote clusters. Remote clusters can be located in different datacenters or geographic regions, and contain indices or data streams that can be replicated with cross-cluster replication or searched by a local cluster using cross-cluster search.
Sniff mode edit
In sniff mode, a cluster is created using a name and a list of seed nodes. When a remote cluster is registered, its cluster state is retrieved from one of the seed nodes and up to three gateway nodes are selected as part of remote cluster requests. This mode requires that the gateway node’s publish addresses are accessible by the local cluster.
Proxy mode edit
In proxy mode, a cluster is created using a name and a single proxy address. When you register a remote cluster, a configurable number of socket connections are opened to the proxy address. The proxy is required to route those connections to the remote cluster. Proxy mode does not require remote cluster nodes to have accessible publish addresses.
How to secure Elasticsearch?
You need to secure access to your remote Elasticsearch instance with a username and password. We recommend securing your remote Elasticsearch instance with a security plugin that requires anyone connecting to it provides authentication credentials. Atlassian provides a free plugin called Buckler for this purpose. Bitbucket Server also supports authentication to Elasticsearch through other plugins that provide basic authentication, like Elastic's Shield plugin.
What file to add elasticsearch parameters?
Add these parameters to your elasticsearch.yml file
How to enable Buckler?
To enable the Buckler for basic HTTP authentication, you add these properties to the file, creating a username and password that Bitbucket will use to access Elasticsearch (configured in a later step).
What is elasticsearch.yml?
The elasticsearch.yml file contains configuration details for your Elasticsearch instance.
Where is the configuration directory in ElasticSearch?
The location of your configuration directory varies depending on how you installed Elasticsearch. For rpm/deb installations the location is typically in /etc/elasticsearch
Does Bitbucket require Elasticsearch?
Bitbucket Data Center requires a remote Elasticsearch instance, as it is not bundled or installed for Bitbucket Data Center.
Step 1: Install Elasticsearch on a remote machine
We don't provide specific instructions for installing Elasticsearch, but a good place to start is the Elasticsearch (6.8.6) installation instructions . Elastic provides installation packages in several different formats here.
Step 2: Configure Elasticsearch
The elasticsearch.yml file contains configuration details for your Elasticsearch instance.
Step 3: Secure Elasticsearch
You need to secure access to your remote Elasticsearch instance with a username and password. We recommend securing your remote Elasticsearch instance with a security plugin that requires anyone connecting to it provides authentication credentials. Atlassian provides a free plugin called Buckler for this purpose.
