Solr6.3快速入门

Posted on | Edited on | In

刚入门做Java，做Solr一个多月了，其实还是了解点皮毛，今天正好看了官方的pdf，从入门开始说起吧。

平时开发是在Windows环境下的，就说说Windows吧

一、环境搭建

  1. 下载Solr引擎，直接去官网，我这里用的是6.3版本的，贴个6.3版本的下载链接吧，Solr6.3
  2. 安装JDK，这个没什么好说的直接1.8，配置好对象的JAVA_HOME

二、安装启动Solr

下载解压缩之后，进入Solr的根目录，执行#./bin/solr start -e cloud -noprompt

Solr在2个节点上运行，一个端口是8983，另一个端口是7574。并自动建立了名称为gettingstarted的collection，此collection有2个shard，每个shard有2个replicas。

shard相当于分片，将一个collection分成块，每块的内容不同
replicas是副本，对每个分片内容的完整拷贝。

Welcome to the SolrCloud example!

Starting up 2 Solr nodes for your example SolrCloud cluster.

Creating Solr home directory D:\env\solr-6.3.0\example\cloud\node1\solr
Cloning D:\env\solr-6.3.0\example\cloud\node1 into
   D:\env\solr-6.3.0\example\cloud\node2

Starting up Solr on port 8983 using command:
D:\env\solr-6.3.0\bin\solr.cmd start -cloud -p 8983 -s "D:\env\solr-6.3.0\example\cloud\node1\solr"


Starting up Solr on port 7574 using command:
D:\env\solr-6.3.0\bin\solr.cmd start -cloud -p 7574 -s "D:\env\solr-6.3.0\example\cloud\node2\solr" -z localhost:9983


Connecting to ZooKeeper at localhost:9983 ...
Uploading D:\env\solr-6.3.0\server\solr\configsets\data_driven_schema_configs\conf for config gettingstarted to ZooKeeper at localhost:9983

Creating new collection 'gettingstarted' using command:
http://localhost:8983/solr/admin/collections?action=CREATE&name=gettingstarted&numShards=2&replicationFactor=2&maxShardsPerNode=2&collection.configName=gettingstarted

{
  "responseHeader":{
    "status":0,
    "QTime":5560},
  "success":{
    "10.1.64.31:8983_solr":{
      "responseHeader":{
        "status":0,
        "QTime":3983},
      "core":"gettingstarted_shard2_replica1"},
    "10.1.64.31:7574_solr":{
      "responseHeader":{
        "status":0,
        "QTime":4296},
      "core":"gettingstarted_shard2_replica2"}}}

Enabling auto soft-commits with maxTime 3 secs using the Config API

POSTing request to Config API: http://localhost:8983/solr/gettingstarted/config
{"set-property":{"updateHandler.autoSoftCommit.maxTime":"3000"}}
Successfully set-property updateHandler.autoSoftCommit.maxTime to 3000

我启动的是solrcloud模式。Solr在2个节点上运行，一个端口是8983，另一个端口是7574。并自动建立了名称为gettingstarted的collection，此collection有2个shard，每个shard有replicas。 好了，直接访问上面的链接，就可以看到它自动为你新建了一个Collection名为gettingstarted。

三、添加索引

由于windows自带的cmd和power shell不支持shell脚本，那么就用git bash吧。安装好git之后，打开git bash，进入Solr的根目录，执行

1
$ bin/post -c gettingstarted example/exampledocs/*.xml

用SimplePostTool 为example/exampledocs目录下的所有xml文件建立索引。exampledocs目录下还有一些其他格式的文件

为JSON文件建立索引

1
$ bin/post -c gettingstarted example/exampledocs/*.json

为CSV文件建立索引

1
$ bin/post -c gettingstarted example/exampledocs/books.csv

为solr安装目录下的docs文件夹中的文件建立索引。

1
$ bin/post -c gettingstarted docs/

四、搜索

打开搜索链接，在这里面就可以搜索你想要的信息啦。

五、简便方法

还有一种启用Solr单机模式的方法，并且自动帮你导入数据

1
$ bin/solr.cmd start -e techproducts
