环境搭建

一.zookeeper

参考:http://blog.chinaunix.net/uid-25135004-id-4214399.html

  

二.solrCloud

参考:http://lucien-zzy.iteye.com/blog/2002463

1.安装tomcat,配置端口。部署solr.war,将solr\example\lib\ext下的jar拷贝到solr\WEB-INF\lib下。

2.创建

/home/solr/solrcloud

/home/solr/solrcloud/config-files (放置solr\example\solr\collection1\conf 下的所有文件)

/home/solr/solrcloud/solr-lib (放置solr\WEB-INF\lib下的所有jar包)

3.配置中文分词器

4.创建solr数据目录

/home/solr/solr-cores

生成solr.xml,如下:

<?xml version="1.0" encoding="UTF-8" ?>
<solr persistent="true">
<logging enabled="true">
<watcher size="100" threshold="INFO" />
</logging>
<cores defaultCoreName="collection1" adminPath="/admin/cores" host="${host:}" hostPort="8080" hostContext="${hostContext:solr}" zkClientTimeout="${zkClientTimeout:15000}">
</cores>
</solr>


5.创建

tomcat/conf/Catalina

tomcat/conf/Catalina/localhost

并创建solr.xml

<?xml version="1.0" encoding="UTF-8"?>
<Context docBase="/soft/apache-tomcat-7.0.37/webapps/solr" debug="0" crossContext="true">
<Environment name="solr/home" type="java.lang.String" value="/home/solr/solr-cores" override="true"/>
</Context>


docBase根据实际情况配置;

solr/home为之前创建的目录:/home/solr/solr-cores

6.修改tomcat/bin/cataina.sh 文件,在最上方加入:JAVA_OPTS="-DzkHost=master:2181,slave1:2181,slave2:2181",或直接使用ip。

将以上配置发布到集群其他机器上。

7.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。执行如下操作:

java -classpath .:/home/solr/solrcloud/solr-lib/* org.apache.solr.cloud.ZkCLI -cmd upconfig -zkhost 192.168.91.128:2181,192.168.91.129:2181,192.168.91.130:2181 -confdir /home/solr/solrcloud/config-files/ -confname myconf


-cmd upconfig:上传配置文件

-confdir:配置文件的目录

-confname:指定对应的名称

java -classpath .:/home/solr/solrcloud/solr-lib/* org.apache.solr.cloud.ZkCLI -cmd linkconfig -collection collection1 -confname myconf -zkhost 192.168.91.128:2181,192.168.91.129:2181,192.168.91.130:2181


-cmd linkconfig:为指定collection"绑定"配置文件

-collection

-confname

8.检查zookeeper的配置信息

zkCli.sh -server ip:port

ls /configs/myconf

ls /live_nodes

9.启动tomcat,创建collection

curl 'http://192.168.91.128:8080/solr/admin/collections?action=CREATE&name=mycollection&numShards=3&replicationFactor=1'


action:CREATE

name:collection名称

numShards:分片数量

replicationFactor:副本集数量

也可以通过zk查询collection的情况:ls /collections/mycollection

-------------------------------

1.ZK CLI

ZooKeeper's Command Line Utility (CLI).


zkcli
Parameters

Short

Parameter Usage

Meaning

-cmd <arg>

CLI Command to be executed:
bootstrap
,
upconfig
,
downconfig
,

,
get
,
getfile
,
put
,
putfile
,
list
or
clear
.

This parameter is mandatory
-z

-zkhost <locations>

ZooKeeper host address.

This parameter is mandatory for all CLI commands.
-c

-collection <name>

For
linkconfig
: name of the collection.
-d

-confdir <path>

For
upconfig
: a directory of configuration files.
-h

-help

Display help text.
-n

-confname <arg>

For
upconfig
,
linkconfig
: name of the configuration set.
-r

-runzk <port>

Run ZooKeeper internally by passing the Solr run port; only for clusters on one machine.
-s

-solrhome <path>

For
bootstrap
or when using
-runzk
: the mandatory solrhome location.
ZooKeeper CLI Examples

Below are some examples of using the zkcli CLI:

Uploading a Configuration Directory

java -classpath example/solr-webapp/WEB-INF/lib/*
org.apache.solr.cloud.ZkCLI -cmd upconfig -zkhost 127.0.0.1:9983
-confdir example/solr/collection1/conf -confname conf1 -solrhome example/solr


Put arbitrary data into a new ZK file

java -classpath example/solr-webapp/WEB-INF/lib/*
org.apache.solr.cloud.ZkCLI -zkhost 127.0.0.1:9983 -put /data.txt 'some data'


Put a local file into a new ZK file

java -classpath example/solr-webapp/WEB-INF/lib/*
org.apache.solr.cloud.ZkCLI -zkhost 127.0.0.1:9983 -putfile /data.txt /some/local/file.txt


Linking a Collection to a Configuration Set

java -classpath example/solr-webapp/webapp/WEB-INF/lib/*
org.apache.solr.cloud.ZkCLI -cmd linkconfig -zkhost 127.0.0.1:9983
-collection collection1 -confname conf1 -solrhome example/solr


Bootstrapping All the Configuration Directories in solr.xml

java -classpath example/solr-webapp/webapp/WEB-INF/lib/*
org.apache.solr.cloud.ZkCLI -cmd bootstrap -zkhost 127.0.0.1:9983
-solrhome example/solr


Scripts

There are scripts in example/cloud-scripts that handle the classpath and class name for you if you are using Solr out of the box with Jetty. Commands then become:

sh zkcli.sh -cmd linkconfig -zkhost 127.0.0.1:9983
-collection collection1 -confname conf1 -solrhome example/solr


2.Managing collections via the collections API

CREATE---

http://localhost:8983/solr/admin/collections?action=CREATE&name=mycollection&numShards=3&replicationFactor=4


name:collection的名称

numShards:指定分片数量(slices)

replicationFactor:副本数量

maxShardsPerNode:默认值为1,注意三个数值:numShards、replicationFactor、liveSolrNode,一个正常的solrCloud集群不容许同一个liveSolrNode上部署同一个shard的多个replic,因此当maxShardsPerNode=1时,numShards*replicationFactor>liveSolrNode时,报错。因此正确时因满足以下条件:

numShards*replicationFactor<liveSolrNode*maxShardsPerNode

createNodeSet:

collection.configName:指定该collection使用那份config,这份config必须存在于zk中。

DELETE---

http://localhost:8983/solr/admin/collections?action=DELETE&name=mycollection


RELOAD---

http://localhost:8983/solr/admin/collections?action=RELOAD&name=mycollection


SPLIT SHARD---

http://localhost:8983/solr/admin/collections?action=SPLITSHARD&collection=<collection_name>&shard=shardId


3.Creating cores via CoreAdmin

curl 'http://localhost:8983/solr/admin/cores?action=CREATE&name=mycore&collection=collection1&shard=shard2'


-------------------------------

Q1:Multiple schemas in the same SolrCloud ?

java -classpath .:/home/solrcloud/solr-lib/* org.apache.solr.cloud.ZkCLI -cmd upconfig -zkhost 10.200.51.190:2224,10.200.51.192:2224,10.200.51.194:2224 -confdir /home/solrcloud/fox-config-files/ -confname foxconf


指定配置文件,上传到zk。

curl 'http://10.200.51.194:2223/solr/admin/collections?action=CREATE&name=fox4&numShards=1&replicationFactor=5&collection.configName=foxconf'


为创建的collection指定collection.configName。
