It is not enough to have a single node cluster. We need to add more nodes, more nodes, and more nodes! (In fact, no more than 2 ).
1) add the second node
Start node1. If node1 is not added to the myad. Local Domain, add it. For more information about how to add a computer to a domain, find a solution.On node1, use clusteradmin to log on (the administrator can also use the clusteradmin account when adding the domain ). Do you still remember what cluste

[MongoDB] mongodb sharded cluster (iii) on windows platform, mongodb Cluster
In the previous two blogs, we elaborated on the working principle and building process of the sharded cluster. In this blog, we will analyze the testing results of the sharded cluster;
First, check the status of the sharded
This paper records the entire process of building elasticsearch clusters using Docker (the 2.1.2 examples used in this article), and process affinity is also applicable to elasticsearch2.x,5.x, and subsequent authors will continue to study es in depth, The next step is to make a retrofit test based on this cluster for source Elasticsearch (hereafter referred to as ES). 1. Environment Introduction
This paper runs the environment ubuntu16.04 + docker17.

Depending on the newly added node type, there are 2 ways to add new nodes to the cluster.
1: If you add a new node that is a master, then we need to create an empty node and then move some hash buckets to this empty node.
2: To add the new node is slave, then we will set the new node as a replica of a
