Wang, Josh.I. OverviewLucene is a text retrieval class library written by the Java language, which is implemented using the inverted-row principle, and SOLR is a text retrieval application service based on Lucene. Solrcloud is a pioneering, zookeeper-based distributed search solution developed by the Solr4.0 version, and the main idea is to use zookeeper as the configuration information Center for the cluster. It can also be said that

Multiple Physical shards form a complete index collection. Solrcloud automatically supports SOLR replication, which can replicate shards and store them in redundancy.

I. INTRODUCTION Solrcloud is a distributed search scheme based on SOLR and zookeeper after the Solr4.0 version. Solrcloud is SOLR based on a zookeeper deployment approach. SOLR can be deployed in a variety of ways, such as stand-alone mode, multiple-machine master-slaver mode. Two. Featured Features Solrcloud has several features: Centralized configuration inform

Solrcloud Usage tutorials, Introduction to PrinciplesSolrcloud is a distributed search scheme based on SOLR and Zookeeper and is one of the core components of the Solr4.0 in development, and its main idea is to use Zookeeper as the configuration Information Center for the cluster. It has several features: ① centralized configuration information ② automatic fault tolerance ③ near real-time search ④ query automatically load balance. Here's a look at the

SolrCloud-5.2.1 cluster deployment and Testing I. Description Solr5 has built-in Jetty service, so you do not need to install and deploy Tomcat. The information on deploying Tomcat on the internet is too extensive. Preparations before deployment: 1. Configure the IP addresses of each host as static IP addresses (ensure that each host can communicate normally. To avoid excessive network transmission, we recommend that you use the same network segment )

Solrcloud is a distributed solution for SOLR, this article briefly introduces the environment configuration of Solrcloud. Because the actual production environment is mainly Linux system, this article will be carried out under the Linux system.This article uses solr4.7 + zookeeper3.4.6 (standalone mode)1 Configure two stand-alone SOLR services, which can be referenced here (broadly similar to Linux and Wind
