Solr的配置网上讲的很多，但是实施总是遇到困难，现总结如下：
1. 从官网下载solr core的源码包，将solrwar包放到tomcat的webapps文件夹下，其它web容器亦然.
运行tomcat ,解压出来solr的文件夹.
2. Single core配置：以solr自带例子做讲解
2.1. 新建solrhome目录:d:/test/solrcore/singlecore ,从solr源码的example包下复制solr包
2.2. 在tomcat 下的 webappss的solr包 WEB-INF目录下修改web.xml的
<env-entry-name>solr/home</env-entry-name>
<env-entry-value> D:/test/solrcore/singlecore</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
2.3. 修改solrhome目录下的solr下的conf的solrconfig.xml文件
<dataDir>D:/test/solrcore/data/singlecore</dataDir>
此目录放置的是solr的data索引文件
2.4. 启动solr控制台，即可
3. multicore 配置：以solr core源码的multicore为例
3.1. 新建solrhome目录:d:/test/solrcore/multicore从solr源码的example下复制multicore目录到在solrhome下
3.2. 在tomcat 下的 webappss的solr包 WEB-INF目录下修改web.xml的
<env-entry-name>solr/home</env-entry-name>
<env-entry-value> D:/test/solrcore/multicore</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
3.2. 修改solrhome目录下的solr下的conf的solrconfig.xml文件
<dataDir>D:/test/solrcore/data/multicore</dataDir>
3.3. 将core0和core1的索引文件放到 D:/test/solrcore/data/multicore目录下
3.4. 启动solr控制台，可以看到二个core，安装完成
4. EmbeddedSolrServer使用
4.1.singleCore使用：
package com.taobao.terminator.allen.SolrjTest;
import org.apache.solr.client.solrj.SolrQuery;
import org.apache.solr.client.solrj.embedded.EmbeddedSolrServer;
import org.apache.solr.common.SolrDocument;
import org.apache.solr.common.SolrDocumentList;
import org.apache.solr.common.SolrInputDocument;
import org.apache.solr.core.CoreContainer;
import org.junit.Test;
public class EmbedSolrServerSingleCoreTest {
private static CoreContainer.Initializer initializer = null;
private static CoreContainer coreContainer = null;
private static EmbeddedSolrServer server = null;
static {
try {
System.setProperty("solr.solr.home", "D://test//solrcore//core0");
initializer = new CoreContainer.Initializer();
coreContainer = initializer.initialize();
server = new EmbeddedSolrServer(coreContainer, "");
} catch (Exception e) {
e.printStackTrace();
}
}
@Test
public void query() throws Exception {
try {
SolrQuery q = new SolrQuery();
q.setQuery("*:*");
q.setStart(0);
q.setRows(20);
SolrDocumentList list = server.query(q).getResults();
System.out.println(list.getNumFound());
} catch (Exception e) {
e.printStackTrace();
} finally {
coreContainer.shutdown();
}
}
@Test
public void deleteAllDoc() throws Exception {
try {
server.deleteByQuery("*:*");
server.commit();
query();
} catch (Exception e) {
e.printStackTrace();
} finally {
coreContainer.shutdown();
}
}
}
4.2.multiCore使用：
package com.taobao.terminator.allen.SolrjTest;
import java.io.File;
import org.apache.solr.client.solrj.SolrQuery;
import org.apache.solr.client.solrj.embedded.EmbeddedSolrServer;
import org.apache.solr.core.CoreContainer;
import org.apache.solr.core.CoreContainer.Initializer;
public class EmbedSolrServerMultiCoreTest {
private static CoreContainer.Initializer initializer = null;
private static CoreContainer coreContainer = null;
private static EmbeddedSolrServer server = null;
static {
try {
System.setProperty("solr.solr.home", "D://test//solrcore//core1");
initializer = new CoreContainer.Initializer();
coreContainer = initializer.initialize();
server = new EmbeddedSolrServer(coreContainer, "");
} catch (Exception e) {
e.printStackTrace();
}
}
public void query() throws Exception {
try {
File f = new File( "D:/test/solrcore/multicore", "solr.xml" );
coreContainer = new Initializer().initialize();
coreContainer.load("D:/test/multicore", f);
coreContainer.setPersistent(true);
server = new EmbeddedSolrServer(coreContainer, "core1");
SolrQuery q = new SolrQuery();
q.setQuery("*:*");
System.out.println(server.query(q).getResults().getNumFound());
} catch (Exception e) {
e.printStackTrace();
} finally {
coreContainer.shutdown();
}
}
}
