Solrcloud安装与使用

准备

• JDK 1.8.0.181
• solr 7.5.0
• zookeeper 3.4.13

安装步骤

zookeeper集群安装

1. 下载zookeeper http://mirror.bit.edu.cn/apache/zookeeper
2. 解压缩zookeeper-3.4.13.tar.gz

   cd /usr/local/app
   tar -xf zookeeper-3.4.13.tar.gz
   mv zookeeper-3.4.13 zookeeper
   

3. 修改zoo.cfg配置文件

   cd /usr/local/app/zookeeper/conf
   vi zoo.cfg
   --------------------------------
   tickTime=2000
   initLimit=10
   syncLimit=5
   dataDir=/usr/local/app/zookeeper/data
   clientPort=2181
   # server.1中的1位器群机器zookeeper服务的myid
   server.1=172.30.1.31:2888:3888
   server.2=172.30.1.32:2888:3888
   server.3=172.30.1.33:2888:3888
   --------------------------------
   

4. data目录创建myid文件

   cd /usr/local/app/zookeeper/
   mkdir data
   vi myid
   --------------------------------
   # 第二台机器为2，依次类推
   1
   --------------------------------
   

5. 启动服务

   ./bin/zkServer.sh start
   

6. 集群状态检查

   # 带所有服务启动命令之后执行
   ./bin/zkServer.sh start
   

solrcloud安装

1. 单机安装所有节点服务，见solr单机版安装
2. 创建chroot

   # 登录任意一台solr节点服务器
   cd /opt/solr/bin/
   ./solr zk mkroot solr -z 172.30.1.31:2181,172.30.1.32:2181,172.30.1.33:2181
   

3. solr集群配置

   # 每个节点执行
   vi /etc/default/solr.in.sh
   --------------------------------------------
   # 修改java运行环境
   SOLR_JAVA_HOME="/usr/local/jdk1.8.0_31"
   # 修改solrcloud配置
   ZK_HOST="172.30.1.32:2181,172.30.1.33:2181/test"
   # 修改内存
   SOLR_JAVA_MEM="-Xms512m -Xmx512m"
   --------------------------------------------
   

4. 创建collection

   # 登录任意节点执行
   cd /opt/solr/bin
   # -c collection名称
   # -shards 分片数量
   # -replicationFactor 副本数量
   ./solr create_collection -c second -d _default -shards 2 -replicationFactor 3
   

5. 修改字段配置
   1. 下载zookeeper管理的配置文件

      # -d 配置文件下载目标目录
      # -n chroot名称
      # -z zookeeper集群地址
      /opt/solr/bin/solr zk downconfig -n second -d ./
      
      
      

   2. 修改下载的配置文件

      vi managed-schema
      -----------------------------------------------------------
      
      
      <schema name="default-config" version="1.6">
        
        <uniqueKey>iduniqueKey>

        <fieldType name="pfloats" class="solr.FloatPointField" docValues="true" multiValued="true"/>
        <fieldType name="pint" class="solr.IntPointField" docValues="true"/>
        <fieldType name="pints" class="solr.IntPointField" docValues="true" multiValued="true"/>
        <fieldType name="plong" class="solr.LongPointField" docValues="true"/>
        <fieldType name="plongs" class="solr.LongPointField" docValues="true" multiValued="true"/>
        <fieldType name="random" class="solr.RandomSortField" indexed="true"/>

        <fieldType name="text_general" class="solr.TextField" positionIncrementGap="100" multiValued="true">
      	<analyzer type="index">
      	  <tokenizer class="solr.StandardTokenizerFactory"/>
      	  <filter class="solr.StopFilterFactory" words="stopwords.txt" ignoreCase="true"/>
      	  <filter class="solr.LowerCaseFilterFactory"/>
      	analyzer>
      	<analyzer type="query">

        <fieldType name="text_ik" class="solr.TextField">

      	  <tokenizer class="org.wltea.analyzer.lucene.IKTokenizerFactory" conf="ik.conf" useSmart="true"/>
      	  <filter class="solr.LowerCaseFilterFactory"/>
      	analyzer>
        fieldType>
      
        
        <field name="_version_" type="plong" indexed="false" stored="false"/>

        <field name="birthday" type="pdate" indexed="true" stored="true"/>
      schema>
      

   3. 上传配置文件到zookeeper

      /opt/solr/bin/solr zk upconfig -n demo -d ./
      

   4. 重启集群

客户端开始使用

• springboot 2.1.1
• solr 7.5

导入依赖

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-data-solrartifactId>
dependency>

application.properties配置

spring.data.solr.zk-host=172.30.1.31:2181,172.30.1.32:2181,172.30.1.33:2181/solr
spring.data.solr.repositories.enabled=true
