solrCloud 4.9 分布式集群部署及注意事项

环境搭建

一.zookeeper

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

现有4台机器 10.14.2.201 10.14.2.202 10.14.2.203 10.14.2.204
安装zookeeper集群 在所有机器上进行
1、下载安装包解压
tar xvf zookeeper-3.4.5.tar.gz -C /export/
cd /export/
ln -s zookeeper-3.4.5 zookeeper 2、设置环境变量
vim /etc/profile
#Set ZooKeeper Enviroment
export ZOOKEEPER_HOME=/export/zookeeper
export PATH=$PATH:$ZOOKEEPER_HOME/bin 3、加载环境变量
source /etc/profile
4、配置zookeeper
cd /export/zookeeper/conf
cp zoo_sample.cfg zoo.cfg
vim zoo.cfg tickTime=2000
initLimit=10
syncLimit=5
dataDir=/export/zookeeper/data
dataLogDir=/export/zookeeper/log
clientPort=2181
server.1=10.14.2.201:2888:3888
server.2=10.14.2.202:2888:3888
server.3=10.14.2.203:2888:3888
server.4=10.14.2.204:2888:3888 5、dataDir和日志目录dataLogDir
mkdir -p /export/zookeeper/data
mkdir -p /export/zookeeper/log 6、在10.14.2.201上
在dataDir目录下创建myid文件
echo 1 > /export/zookeeper/data/myid myid中的数字与zoo.cfg中的"server.数字=ip或者域名:port1:port2"相对应,
配置文件中10.14.2.201对应的server.数字是1 所以myid的数字应为1 7、在10.14.2.202上
在dataDir目录下创建myid文件
echo 2 > /export/zookeeper/data/myid 8、在10.14.2.203上
在dataDir目录下创建myid文件
echo 3 > /export/zookeeper/data/myid 9、在10.14.2.204上
在dataDir目录下创建myid文件
echo 4 > /export/zookeeper/data/myid 在所用机器上执行
10、修改权限
chown hadoop.hadoop -R /export/zookeeper/
chown hadoop.hadoop -R /export/zookeeper 11、启动zookeeper
/export/zookeeper/bin/zkServer.sh start 12、观察zookeeper状态
1> 10.14.2.201
# /export/zookeeper/bin/zkServer.sh status
JMX enabled by default
Using config: /export/zookeeper/bin/../conf/zoo.cfg
Mode: follower 2> 10.14.2.202
# /export/zookeeper/bin/zkServer.sh status
JMX enabled by default
Using config: /export/zookeeper/bin/../conf/zoo.cfg
Mode: follower 3> 10.14.2.203
# /export/zookeeper/bin/zkServer.sh status
JMX enabled by default
Using config: /export/zookeeper/bin/../conf/zoo.cfg
Mode: leader 4> 10.14.2.204
# /export/zookeeper/bin/zkServer.sh status
JMX enabled by default
Using config: /export/zookeeper/bin/../conf/zoo.cfg
Mode: follower 13、此时zookeeper已安装并启动完毕

  

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="" threshold="INFO" />
</logging>
<cores defaultCoreName="collection1" adminPath="/admin/cores" host="${host:}" hostPort="" hostContext="${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="" 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: bootstrapupconfigdownconfiglinkconfigmakepathgetgetfileput,putfilelist 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 upconfiglinkconfig: 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:
-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。
