SOLR Cluster Environment Setup

SOLR cluster environment setup

A. Prepare

1. Download:

solr-4.4.0.zip SOLR installation package

apache-tomcat-7.0.47.tar.gz Tomcat installation package

2. Description:

Where the cluster environment using nginx for distribution (also can use Apache),nginx installation is no longer introduced here. We have a total of four machines, respectively, as follows

10.10.42.164

10.10.42.165

10.10.42.166

10.10.42.167

where 10.10.42.164 as the main node installation nginx,SOLR Master node, the remaining three installed SOLR slave node.

two. Installation

1. Tomcat Installation

CP apache-tomcat-7.0.47.tar.gz/opt

Cd/opt

TAR-ZXVF apache-tomcat-7.0.47.tar.gz

MV apache-tomcat-7.0.57 Tomcat

Start Tomcat

Opt/tomcat /bin/startup.sh

Visit http://127.0.0.1:8080to see Tomcat 's launch welcome page to prove that Tomcat is configured correctly

(1) Start the Tomcat service:

#/opt/tomcat/bin/startup.sh

#/opt/tomcat/bin/catalina.sh Start

(2) Close the Tomcat service:

#/opt/tomcat/bin/shutdown.sh

#/opt/tomcat/bin/catalina.sh stop

2. SOLR Installation

1. Unzip the SOLR and, under solr-4.4.0 \example\webapps , have a solr.war copy it to Tomcat/webapps directory, remember not to change the name of the War package

2. Add the slf4j,commons-loggin.jar to the apache-tomcat-7.0.42\webapps\solr\web-inf\lib . The 2 jar packages are missing from Solr 's own war package

3. Configure Solr.home. add such a section to Web. XML below apache-tomcat-7.0.42\webapps\solr\web-inf

<env-entry>

<env-entry-name>solr/home</env-entry-name>

<env-entry-value>/opt/solr/home</env-entry-value>

<env-entry-type>java.lang.String</env-entry-type>

</env-entry>

Change the E:\solr_home to your own directory, and then copy the solr-4.4.0 \EXAMPLE\SOLR to your ${solr_home}

4. do the same for all nodes.

5. Modify the ${solr_home}/solr/conf/solrconfig.xml of the master node (10.10.42.164)

<requesthandler name= "/replication" class= "SOLR. Replicationhandler ">

<lst name= "Master" >

<str name= "Replicateafter" >commit</str>

<str name= "Replicateafter" >startup</str>

<str name= "Conffiles" >schema.xml,stopwords.txt</str>

</lst>

<str name= "Maxnumberofbackups" >3</str>

</requestHandler>

6. Modify the slave node

<requesthandler name= "/replication" class= "SOLR. Replicationhandler ">

<str name= "Maxnumberofbackups" >8</str>

<lst name= "Slave" >

<str name= "MasterUrl" >http://10.10.42.164:8080/solrmaster/replication</str>

<str name= "PollInterval" >00:00:60</str>

</lst>

</requestHandler>

three. Configure Nginx

Modify nginx_home/nginx.conf

Add the following content

Upstream mango_solr{

Ip_hash;

Server 10.10.42.165:8080 max_fails=2 fail_timeout=5s;

Server 10.10.42.166:8080 max_fails=2 fail_timeout=5s;

Server 10.10.42.167:8080 max_fails=2 fail_timeout=5s;

}

location/solr{

Proxy_pass HTTP://MANGO_SOLR;

}
