1 下载地址 http://lucene.apache.org/solr/

wget https://mirrors.tuna.tsinghua...
tar -zxvf solr-8.1.0.tgz

2 运行 停止

切换到目录(solr-8.1.0/bin)
./solr start -force
./solr start -p 9529 -force (指定端口)
./solr stop -all
启动错误提示 Your Max Processes Limit is currently 将solr-8.1.0/bin/solr.in.sh文件中,SOLR_ULIMIT_CHECKS设置为false
浏览器输入http://127.0.0.1:9529/solr

3 修改时区

修改文件 solr-8.1.0/bin/solr.in.sh
SOLR_TIMEZONE=PRC

4 创建core实例

首先去目录solr-8.1.0/server/solr/ 创建一个名字为new_core的文件夹(如:fgou)
然后拷贝把目录solr-8.1.0/server/configsets/basic_configs下的conf目录拷贝到fgou目录下
cp -r /usr/local/src/solr-8.1.0/server/solr/configsets/_default/conf  /usr/local/src/solr-8.1.0/server/solr/fgou/
然后再点击创建即可

5 配置中文分词

下载IK分词器 https://pan.baidu.com/s/1fZ52... 提取码:f76c
IKAnalyzer下载后解压会有如下文件

把核心jar文件复制到solr WEB应用的lib文件夹下 solr学习笔记

把配置文件和词库等文件复制到WEB应用的classes文件夹下,如果子WEB-INF下没有这个文件夹自己创建即可 solr学习笔记

在配置文件managed-schema中增加如下配置

<fieldType name="fgou_ik" class="solr.TextField">
    <analyzer type="index">
      <tokenizer class="org.wltea.analyzer.lucene.IKTokenizerFactory" useSmart="false"/>
   </analyzer>
    <analyzer type="query">
      <tokenizer class="org.wltea.analyzer.lucene.IKTokenizerFactory" useSmart="true"/>
    </analyzer>
</fieldType>
重启服务 这样就可以选择到ik分词了,创建个

6 导入MYSQL数据

首先在D:/server/solr-7.4.0/dist目录下复制如下的jar包
solr学习笔记
复制到 D:/server/solr-7.4.0/server/solr-webapp/webapp/WEB-INF/lib
再到 https://search.maven.org/search?q=mysql-connector下载mysql-connector
复制到D:/server/solr-7.4.0/server/solr-webapp/webapp/WEB-INF/lib目录下
在D:/server/solr-7.4.0/server/solr/fgou/conf/solrconfig.xml配置数据库文件信息
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
       <lst name="defaults">
           <str name="config">fgou-config.xml</str>
       </lst>
</requestHandler>

创建fgou-config.xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<dataConfig>
<dataSource typ="JdbcDataSource"
    driver="com.mysql.cj.jdbc.Driver"
    url="jdbc:mysql://127.0.0.1/fgou?useSSL=true&amp;serverTimezone=UTC&amp;verifyServerCertificate=false&amp;allowMultiQueries=true&amp;useUnicode=true&amp;characterEncoding=UTF-8"
    user="root"
    password="hufeng"
/>
<document>
    <entity pk="gid" dataSource="JdbcDataSource" name="goods" query="select gid,gname,group_price,sell_num,status from goods where status=1" 
            deltaQuery="select gid from goods where status = 1 and addtime > '${dataimporter.last_index_time}'" #新增修改索引
            deletedPkQuery="select gid from goods where status != 1 and addtime > '${dataimporter.last_index_time}'" #删除索引             
            deltaImportQuery="select gid,gname,group_price,sell_num,status from goods where gid='${dataimporter.delta.gid}'"
    >
        <field column="gid" name="gid"/>
        <field column="gname" name="gname"/>
        <field column="group_price" name="group_price"/>
        <field column="sell_num" name="sell_num"/>
        <field column="status" name="status"/>
    </entity>
</document>
</dataConfig>

在managed-schema中配置字段检索使用的分词器

修改:<uniqueKey>gid</uniqueKey>
  新增:
  <field name="goods" type="fgou_ik" uninvertible="true" indexed="true" stored="true"/>
  <field name="gid" type="string" multiValued="false" indexed="true" required="true" stored="true"/>
  <field name="gname" type="fgou_ik" indexed="true" stored="true"/>
  <field name="group_price" type="pdouble" indexed="true" stored="true"/>
  <field name="sell_num" type="pint" indexed="true" stored="true"/>
  <field name="status" type="pint" indexed="true" stored="true"/>

    public function solrQuery($core='fgou',$fl='gid',$fq='status:1',$q='gid:1',$sort='gid desc,sell desc',$start=0,$rows=10){
         $fl = urlencode($fl);
         $fq = urlencode($fq);
         $q = urlencode($q);
         $sort = urlencode($sort);

         $res = file_get_contents($url);
         $resArr = json_decode($res,true);
         return $resArr['response']; 
     } 
    //solr 更新索引 
    public function solrIndex($core='fgou'){
         $url = 'http://127.0.0.1:9529/solr/fgou/dataimport?indent=on&wt=json';
         $param = [

             'verbose'=>'false',
             'clean'=>'false',
             'commit'=>'true',
             'core'=>$core,
             'name'=>'dataimport',
         ];
         $this->httpCurl($url,$param); }
     }
