SolrCloud 4.3.1+Tomcat 7安装配置实践
我们使用Solr Replication可以实现Solr服务器的可用性，即使某一个索引副本由于磁盘介质故障或者误操作删除等，其他的多个复制副本仍然可以提供服务。如果只是单纯的基于Solr Replication技术，只能对一个索引进行管理维护，当索引数据达到一定规模，搜索的性能成了瓶颈，除了重新规划设计索引，实现逻辑划分以外，没有更好地方法实现查询服务器的可扩展性。
SolrCloud就是为了解决这个问题而提出的。SolrCloud通过ZooKeeper集群来进行协调，使一个索引（SolrCloud中叫做一个Collection）进行分片，各个分片可以分布在不同的物理节点上，而且，对于同一个Collection的多个分片（Shard）之间没有交集，亦即，多个物理分片组成一个完成的索引Collection。为了保证分片数据的可用性，SolrCloud自动支持Solr Replication，可以同时对分片进行复制，冗余存储。下面，我们基于Solr最新的4.3.1版本进行安装配置SolrCloud集群，通过实践来实现索引数据的分布存储和检索。
准备工作
- 服务器信息
三台服务器：
[plain] view plain copy
- 10.95.3.61 master
- 10.95.3.62 slave1
- 10.95.3.65 slave4
- ZooKeeper集群配置
安装ZooKeeper集群，在上面3分节点上分别安装，使用的版本是zookeeper-3.4.5。
首先，在master节点上配置zoo.cfg，内容如下所示：
[plain] view plain copy
- [[email protected] ~]$ vi applications/zookeeper/zookeeper-3.4.5/conf/zoo.cfg
- # The number of milliseconds of each tick
- tickTime=2000
- # The number of ticks that the initial
- # synchronization phase can take
- initLimit=10
- # The number of ticks that can pass between
- # sending a request and getting an acknowledgement
- syncLimit=5
- # the directory where the snapshot is stored.
- # do not use /tmp for storage, /tmp here is just
- # example sakes.
- dataDir=/home/hadoop/applications/zookeeper/zookeeper-3.4.5/data
- # the port at which the clients will connect
- clientPort=2188
- dataLogDir=/home/hadoop/applications/zookeeper/zookeeper-3.4.5/data/logs
- server.1=master:4888:5888
- server.2=slave1:4888:5888
- server.3=slave4:4888:5888
- #
- # Be sure to read the maintenance section of the
- # administrator guide before turning on autopurge.
- #
- # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
- #
- # The number of snapshots to retain in dataDir
- #autopurge.snapRetainCount=3
- # Purge task interval in hours
- # Set to "0" to disable auto purge feature
- #autopurge.purgeInterval=1
然后，创建对应的数据存储目录后，可以直接将该配置复制到其他两个节点上：
[plain] view plain copy
- [[email protected] ~]$ scp -r applications/zookeeper/zookeeper-3.4.5 [email protected]:~/applications/zookeeper/
- [[email protected] ~]$ scp -r applications/zookeeper/zookeeper-3.4.5 [email protected]:~/applications/zookeeper/
启动ZooKeeper集群，在每个节点上分别启动ZooKeeper服务：
[plain] view plain copy
- [[email protected] ~]$ cd applications/zookeeper/zookeeper-3.4.5/
- [[email protected] zookeeper-3.4.5]$ bin/zkServer.sh start
- [[email protected] ~]$ cd applications/zookeeper/zookeeper-3.4.5/
- [[email protected] zookeeper-3.4.5]$ bin/zkServer.sh start
- [[email protected] ~]$ cd applications/zookeeper/zookeeper-3.4.5/
- [[email protected] zookeeper-3.4.5]$ bin/zkServer.sh start
[plain] view plain copy
- [[email protected] zookeeper-3.4.5]$ bin/zkServer.sh status
- JMX enabled by default
- Using config: /home/hadoop/applications/zookeeper/zookeeper-3.4.5/bin/../conf/zoo.cfg
- Mode: follower
- [[email protected] zookeeper-3.4.5]$ bin/zkServer.sh status
- JMX enabled by default
- Using config: /home/hadoop/applications/zookeeper/zookeeper-3.4.5/bin/../conf/zoo.cfg
- Mode: follower
- [[email protected] zookeeper-3.4.5]$ bin/zkServer.sh status
- JMX enabled by default
- Using config: /home/hadoop/applications/zookeeper/zookeeper-3.4.5/bin/../conf/zoo.cfg
- Mode: leader
可以看到，slave4节点是ZooKeeper集群服务Leader。
- SolrCloud相关目录
我们选择/home/hadoop/applications/solr/cloud目录存放Solr的库文件和配置文件，该目录下有lib和multicore两个子目录。
另外，还有一个存储索引的目录，设置为/home/hadoop/applications/storage/cloud/data。
SolrCloud配置
首先在一个节点上对SOLR进行配置，我们选择master节点。
1、SOLR基本配置
将下载的SOLR的压缩包解压缩，将solr-4.3.1\example\webapps\solr.war解开，将solr-4.3.1\example\webapps\solr\WEB-INF\lib和solr-4.3.1\example\lib\ext中的jar文件拷贝到solr-4.3.1\example\webapps\solr\WEB-INF\lib中，并将解开的solr目录改名为solr-cloud，然后传到服务器的Tomcat下的webapps目录下。
将solr-4.3.1\example\webapps\solr\WEB-INF\lib和solr-4.3.1\example\lib\ext下面的jar文件都拷贝到指定目录/home/hadoop/applications/solr/cloud/lib/中：
[plain] view plain copy
- [[email protected] ~]$ ls /home/hadoop/applications/solr/cloud/lib/
- commons-cli-1.2.jar lucene-analyzers-common-4.3.1.jar lucene-suggest-4.3.1.jar
- commons-codec-1.7.jar lucene-analyzers-kuromoji-4.3.1.jar noggit-0.5.jar

- commons-io-2.1.jar lucene-codecs-4.3.1.jar org.restlet.ext.servlet-2.1.1.jar
- commons-lang-2.6.jar lucene-core-4.3.1.jar slf4j-api-1.6.6.jar
- guava-13.0.1.jar lucene-grouping-4.3.1.jar slf4j-log4j12-1.6.6.jar
- httpclient-4.2.3.jar lucene-highlighter-4.3.1.jar solr-core-4.3.1.jar
- httpcore-4.2.2.jar lucene-memory-4.3.1.jar solr-solrj-4.3.1.jar
- httpmime-4.2.3.jar lucene-misc-4.3.1.jar spatial4j-0.3.jar
- jcl-over-slf4j-1.6.6.jar lucene-queries-4.3.1.jar wstx-asl-3.2.7.jar
- jul-to-slf4j-1.6.6.jar lucene-queryparser-4.3.1.jar zookeeper-3.4.5.jar
- log4j-1.2.16.jar lucene-spatial-4.3.1.jar
目录/home/hadoop/applications/solr/cloud/multicore的结构，如图所示：
下面，我们对上面conf目录下的配置文件进行说明：
- schema.xml文件
[html] view plain copy
-
-
-
-

- solrconfig.xml文件
[html] view plain copy

solr
- solrcore.properties文件
[plain] view plain copy
- solr.shard.data.dir=/home/hadoop/applications/storage/cloud/data
属性solr.shard.data.dir在solrconfig.xml文件中北引用过，指定索引数据的存放位置。
- solr.xml文件
该文件中指定了ZooKeeper的相关配置，已经Solr Core的配置内容：
[html] view plain copy
注意：这里，我们并没有配置任何的core元素，这个等到整个配置安装完成之后，通过SOLR提供的REST接口，来实现Collection以及Shard的创建，从而来更新这些配置文件。
2、ZooKeeper管理监控配置文件
SolrCloud是通过ZooKeeper集群来保证配置文件的变更及时同步到各个节点上，所以，需要将配置文件上传到ZooKeeper集群中：
[plain] view plain copy
- [[email protected] ~]$ java -classpath .:/home/hadoop/applications/solr/cloud/lib/* org.apache.solr.cloud.ZkCLI -cmd upconfig -zkhost master:2188,slave1:2188,slave4:2188 -confdir /home/hadoop/applications/solr/cloud/multicore/collection1/conf -confname myconf
- [[email protected] ~]$ java -classpath .:/home/hadoop/applications/solr/cloud/lib/* org.apache.solr.cloud.ZkCLI -cmd linkconfig -collection collection1 -confname myconf -zkhost master:2188,slave1:2188,slave4:2188
上传完成以后，我们检查一下ZooKeeper上的存储情况：
[plain] view plain copy
- [[email protected] ~]$ cd applications/zookeeper/zookeeper-3.4.5/
- [[email protected] zookeeper-3.4.5]$ bin/zkCli.sh -server master:2188
- ...
- [zk: master:2188(CONNECTED) 0] ls /
- [configs, collections, zookeeper]
- [zk: master:2188(CONNECTED) 2] ls /configs
- [myconf]
- [zk: master:2188(CONNECTED) 3] ls /configs/myconf
- [solrcore.properties, solrconfig.xml, schema.xml]
3、Tomcat配置与启动
在Tomcat的启动脚本bin/catalina.sh中，增加如下配置：
[plain] view plain copy
- JAVA_OPTS="-server -Xmx4096m -Xms1024m -verbose:gc -Xloggc:solr_gc.log -Dsolr.solr.home=/home/hadoop/applications/solr/cloud/multicore -DzkHost=master:2188,slave1:2188,slave4:2188"
启动Tomcat服务器：
[plain] view plain copy
- [[email protected] ~]$ cd servers/apache-tomcat-7.0.42
- [[email protected] apache-tomcat-7.0.42]$ bin/catalina.sh start
[plain] view plain copy

这时候，SolrCloud集群中只有一个活跃的节点，而且默认生成了一个collection1实例，这个实例实际上虚拟的，因为通过web界面无法访问 http://master:8888/solr-cloud/，看不到任何有关SolrCloud的信息，如图所示：
4、同步数据和配置信息，启动其他节点
在另外两个节点上安装Tomcat和Solr服务器，只需要拷贝对应的目录即可：
[plain] view plain copy
- [[email protected] ~]$ scp -r servers/ [email protected]:~/
- [[email protected] ~]$ scp -r servers/ [email protected]:~/
- [[email protected] ~]$ scp -r applications/solr/cloud [email protected]:~/applications/solr/
- [[email protected] ~]$ scp -r applications/solr/cloud [email protected]:~/applications/solr/
- [[email protected] ~]$ mkdir -p applications/storage/cloud/data/
- [[email protected] ~]$ mkdir -p applications/storage/cloud/data/
启动其他Solr服务器节点：
[plain] view plain copy
- [[email protected] ~]$ cd servers/apache-tomcat-7.0.42
- [[email protected] apache-tomcat-7.0.42]$ bin/catalina.sh start
- [[email protected] ~]$ cd servers/apache-tomcat-7.0.42
- [[email protected] apache-tomcat-7.0.42]$ bin/catalina.sh start
查看ZooKeeper集群中数据状态：
[plain] view plain copy
- [zk: master:2188(CONNECTED) 3] ls /live_nodes
- [10.95.3.65:8888_solr-cloud, 10.95.3.61:8888_solr-cloud, 10.95.3.62:8888_solr-cloud]
这时，已经存在3个活跃的节点了，但是SolrCloud集群并没有更多信息，访问 http://master:8888/solr-cloud/后，同上面的图是一样的，没有SolrCloud相关数据。
5、创建Collection、Shard和Replication
- 创建Collection及初始Shard
直接通过REST接口来创建Collection，如下所示：
[plain] view plain copy
- [[email protected] ~]$ curl 'http://master:8888/solr-cloud/admin/collections?action=CREATE&name=mycollection&numShards=3&replicationFactor=1'
上面链接中的几个参数的含义，说明如下：
[plain] view plain copy
- name 待创建Collection的名称
- numShards 分片的数量
- replicationFactor 复制副本的数量
执行上述操作如果没有异常，已经创建了一个Collection，名称为mycollection，而且每个节点上存在一个分片。这时，也可以查看ZooKeeper中状态：
[plain] view plain copy
- [zk: master:2188(CONNECTED) 5] ls /collections
- [mycollection, collection1]
- [zk: master:2188(CONNECTED) 6] ls /collections/mycollection
- [leader_elect, leaders]
可以通过Web管理页面，访问 http://master:8888/solr-cloud/#/~cloud，查看SolrCloud集群的分片信息，如图所示：
由上图可以看到，对应节点上SOLR分片的对应关系：
[plain] view plain copy
- shard3 10.95.3.61 master
- shard1 10.95.3.62 slave1
- shard2 10.95.3.65 slave4
实际上，我们从master节点可以看到，SOLR的配置文件内容，已经发生了变化，如下所示：
[html] view plain copy
- [[email protected] ~]$ cat applications/solr/cloud/multicore/solr.xml
-
-
- 创建Replication
下面对已经创建的初始分片进行复制。
shard1已经在slave1上，我们复制分片到master和slave4上，执行如下命令：
shard1已经在slave1上，我们复制分片到master和slave4上，执行如下命令：
[plain] view plain copy
- [[email protected] ~]$ curl 'http://master:8888/solr-cloud/admin/cores?action=CREATE&collection=mycollection&name=mycollection_shard1_replica_2&shard=shard1'
- [[email protected] ~]$ curl 'http://master:8888/solr-cloud/admin/cores?action=CREATE&collection=mycollection&name=mycollection_shard1_replica_3&shard=shard1'
- [[email protected] ~]$ curl 'http://slave4:8888/solr-cloud/admin/cores?action=CREATE&collection=mycollection&name=mycollection_shard1_replica_4&shard=shard1'
最后的结果是，slave1上的shard1，在master节点上有2个副本，名称为mycollection_shard1_replica_2和mycollection_shard1_replica_3，在slave4节点上有一个副本，名称为mycollection_shard1_replica_4.
也可以通过查看master和slave4上的目录变化，如下所示：
[plain] view plain copy
- [[email protected] ~]$ ll applications/solr/cloud/multicore/
- 总用量 24
- drwxrwxr-x. 4 hadoop hadoop 4096 8月 1 09:58 collection1
- drwxrwxr-x. 3 hadoop hadoop 4096 8月 1 15:41 mycollection_shard1_replica_2
- drwxrwxr-x. 3 hadoop hadoop 4096 8月 1 15:42 mycollection_shard1_replica_3
- drwxrwxr-x. 3 hadoop hadoop 4096 8月 1 15:23 mycollection_shard3_replica1
- -rw-rw-r--. 1 hadoop hadoop 784 8月 1 15:42 solr.xml
- -rw-rw-r--. 1 hadoop hadoop 1004 8月 1 10:02 zoo.cfg
- [[email protected] ~]$ ll applications/solr/cloud/multicore/
- 总用量 20
- drwxrwxr-x. 4 hadoop hadoop 4096 8月 1 14:53 collection1
- drwxrwxr-x. 3 hadoop hadoop 4096 8月 1 15:44 mycollection_shard1_replica_4
- drwxrwxr-x. 3 hadoop hadoop 4096 8月 1 15:23 mycollection_shard2_replica1
- -rw-rw-r--. 1 hadoop hadoop 610 8月 1 15:44 solr.xml
- -rw-rw-r--. 1 hadoop hadoop 1004 8月 1 15:08 zoo.cfg
其中，mycollection_shard3_replica1和mycollection_shard2_replica1都是创建Collection的时候自动生成的分片，也就是第一个副本。
通过Web界面，可以更加直观地看到shard1的情况，如图所示：
我们再次从master节点可以看到，SOLR的配置文件内容，又发生了变化，如下所示：
[html] view plain copy
- [[email protected] ~]$ cat applications/solr/cloud/multicore/solr.xml
-
-
-
-
到此为止，我们已经基于3个物理节点，配置完成了SolrCloud集群。

我们向已经搭建好的SolrCloud集群，执行索引数据的操作。这里，实现了一个简易的客户端，代码如下所示：
[java] view plain copy
- package org.shirdrn.solr.indexing;
- import java.io.IOException;
- import java.net.MalformedURLException;
- import java.text.DateFormat;
- import java.text.SimpleDateFormat;
- import java.util.Date;
- import org.apache.solr.client.solrj.SolrServerException;
- import org.apache.solr.client.solrj.impl.CloudSolrServer;
- import org.apache.solr.common.SolrInputDocument;
- import org.shirdrn.solr.data.BuildingSampleGenerator;
- import org.shirdrn.solr.data.BuildingSampleGenerator.Coordinate;
- public class CloudSolrClient {
- private CloudSolrServer cloudSolrServer;
- public synchronized void open(final String zkHost, final String defaultCollection,
- int zkClientTimeout, final int zkConnectTimeout) {
- if (cloudSolrServer == null) {
- try {
- cloudSolrServer = new CloudSolrServer(zkHost);
- cloudSolrServer.setDefaultCollection(defaultCollection);
- cloudSolrServer.setZkClientTimeout(zkClientTimeout);
- cloudSolrServer.setZkConnectTimeout(zkConnectTimeout);
- } catch (MalformedURLException e) {
- System.out
- .println("The URL of zkHost is not correct!! Its form must as below:\n zkHost:port");
- e.printStackTrace();
- } catch (Exception e) {
- e.printStackTrace();
- }
- }
- }
- public void addDoc(long id, String area, int buildingType, String category,
- int temperature, String code, double latitude, double longitude, String when) {
- try {
- SolrInputDocument doc = new SolrInputDocument();
- doc.addField("id", id);
- doc.addField("area", area);
- doc.addField("building_type", buildingType);
- doc.addField("category", category);
- doc.addField("temperature", temperature);
- doc.addField("code", code);
- doc.addField("latitude", latitude);
- doc.addField("longitude", longitude);
- doc.addField("when", when);
- cloudSolrServer.add(doc);
- cloudSolrServer.commit();
- } catch (SolrServerException e) {
- System.err.println("Add docs Exception !!!");
- e.printStackTrace();
- } catch (IOException e) {
- e.printStackTrace();
- } catch (Exception e) {
- System.err.println("Unknowned Exception!!!!!");
- e.printStackTrace();
- }
- }
- public static void main(String[] args) {
- final String zkHost = "master:2188";
- final String defaultCollection = "mycollection";
- final int zkClientTimeout = 20000;
- final int zkConnectTimeout = 1000;
- CloudSolrClient client = new CloudSolrClient();
- client.open(zkHost, defaultCollection, zkClientTimeout, zkConnectTimeout);
- BuildingSampleGenerator gen = new BuildingSampleGenerator();
- final DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
- for(int i = 0; i < 10000; i++) {
- long id = gen.genId();
- String area = gen.genArea();
- int buildingType = gen.genBuildingType();
- String category = gen.genBuildingCategory();
- int temperature = gen.genTemperature();
- String code = gen.genCode();
- Coordinate coord = gen.genCoordinate();
- double latitude = coord.getLatitude();
- double longitude = coord.getLongitude();
- String when = df.format(new Date());
- client.addDoc(id, area, buildingType, category, temperature, code, latitude, longitude, when);
- }
- }
- }
当然，也可以从Web管理页面上来管理各个分片的副本数据，比如某个分片具有太多的副本，通过页面上的删除掉（unload）该副本，实际该副本的元数据信息被从ZooKeeper集群维护的信息中删除，在具体的节点上的副本数据并没有删除，而只是处于离线状态，不能提供服务。
搜索数据
我们可以执行搜索，执行如下搜索条件：
[plain] view plain copy
- http://master:8888/solr-cloud/mycollection/select?q=北京 纽约&fl=*&fq=category:公寓&fq=building_type:2&start=0&rows=10
搜索结果，如下所示：
[html] view plain copy
可以查看对应的日志，示例如下所示：
[plain] view plain copy
- 2013-08-05 18:38:26.814 [http-bio-8888-exec-228] INFO org.apache.solr.core.SolrCore – [mycollection_shard1_0_replica2] webapp=/solr-cloud path=/select params={NOW=1375699145633&shard.url=10.95.3.62:8888/solr-cloud/mycollection_shard1_0_replica1/|10.95.3.61:8888/solr-cloud/mycollection_shard1_0_replica3/&fl=id,score&start=0&q=北京+纽约&distrib=false&wt=javabin&isShard=true&fsv=true&fq=category:公寓&fq=building_type:2&version=2&rows=10} hits=41529 status=0 QTime=102
- 2013-08-05 18:39:06.203 [http-bio-8888-exec-507] INFO org.apache.solr.core.SolrCore – [mycollection_shard3_replica1] webapp=/solr-cloud path=/select params={fl=*&start=0&q=北京+纽约&fq=category:公寓&fq=building_type:2&rows=10} hits=201568 status=0 QTime=570
相关问题
1、我在进行Collection的创建的时候，当前有4个节点，在ZooKeeper集群中注册，执行如下命令：
[plain] view plain copy
- [[email protected] multicore]$ curl 'http://slave1:8888/solr-cloud/admin/collections?action=CREATE&name=tinycollection&numShards=2&replicationFactor=3'
出现异常：
[html] view plain copy
根据上面异常信息可知，当前有4个节点可用，但是我在创建Collection的时候，指定两个Shard，同时复制因子是3，所以最低要求，需要6个节点。所以，可以减少复制因子，例如replicationFactor=2，表示一共存在两个副本（Leader分片和另一个副本），然后再执行创建Collection的操作就不会报错了。
