Solr 7.2 cluster deployment details

Solr 7.2 cluster deployment details
Cluster: high availability, backup, and data sharding

Four tomcat servers are required.

1. tomcat port number (three ports 8080, and are used by default)

Tomcat Service	Occupied port
Tomcat1	6005, 6060, 6009
Tomcat2	7005, 7070, 7009
Tomcat3	8005, 8080, 8009
Tomcat4	9005, 9090, 9009

2. Create a solr cluster directory and copy the solr of a single node to this directory in four copies.

Create directory

[Root @ node004] # mkdir-p/usr/local/solrCloud

Copy A Single Node

[Root @ node004 ~] # Cp/usr/local/solr/usr/local/solrCloud/solr1-rf

[Root @ node004 ~] # Cp/usr/local/solr/usr/local/solrCloud/solr2-rf

[Root @ node004 ~] # Cp/usr/local/solr/usr/local/solrCloud/solr3-rf

[Root @ node004 ~] # Cp/usr/local/solr/usr/local/solrCloud/solr4-rf

Note: delete core. properties under each solrhome instance directory.

[Root @ node004 ~] # Rm/usr/local/solrCloud/solr1/home/jonychen/core. properties-rf
[Root @ node004 ~] # Rm/usr/local/solrCloud/solr2/home/jonychen/core. properties-rf
[Root @ node004 ~] # Rm/usr/local/solrCloud/solr3/home/jonychen/core. properties-rf
[Root @ node004 ~] # Rm/usr/local/solrCloud/solr4/home/jonychen/core. properties-rf

3. Modify 16 configuration files in solr 3.1

Solr. xml

[Root @ node004 ~] # Vi/usr/local/solrCloud/solr1/home/solr. xml

 

[Root @ node004 ~] # Vi/usr/local/solrCloud/solr2/home/solr. xml
[Root @ node004 ~] # Vi/usr/local/solrCloud/solr3/home/solr. xml
[Root @ node004 ~] # Vi/usr/local/solrCloud/solr4/home/solr. xml

3.2 tomcat configuration file server. xml

[Root @ node004 ~] # Vi/usr/local/solrCloud/solr1/apache-tomcat-8.5.24/conf/server. xml

[Root @ node004 ~] # Vi/usr/local/solrCloud/solr2/apache-tomcat-8.5.24/conf/server. xml
[Root @ node004 ~] # Vi/usr/local/solrCloud/solr3/apache-tomcat-8.5.24/conf/server. xml
[Root @ node004 ~] # Vi/usr/local/solrCloud/solr4/apache-tomcat-8.5.24/conf/server. xml

　　　　

Web. xml

[Root @ node004 ~] # Vi/usr/local/solrCloud/solr1/apache-tomcat-8.5.24/webapps/solr/WEB-INF/web. xml

[Root @ node004 ~] # Vi/usr/local/solrCloud/solr2/apache-tomcat-8.5.24/webapps/solr/WEB-INF/web. xml
[Root @ node004 ~] # Vi/usr/local/solrCloud/solr3/apache-tomcat-8.5.24/webapps/solr/WEB-INF/web. xml
[Root @ node004 ~] # Vi/usr/local/solrCloud/solr4/apache-tomcat-8.5.24/webapps/solr/WEB-INF/web. xml

 

Catalina. sh

[Root @ node004 ~] # Vi/usr/local/solrCloud/solr1/apache-tomcat-8.5.24/bin/catalina. sh

[Root @ node004 ~] # Vi/usr/local/solrCloud/solr2/apache-tomcat-8.5.24/bin/catalina. sh
[Root @ node004 ~] # Vi/usr/local/solrCloud/solr3/apache-tomcat-8.5.24/bin/catalina. sh
[Root @ node004 ~] # Vi/usr/local/solrCloud/solr4/apache-tomcat-8.5.24/bin/catalina. sh

4. Upload the configuration file to zookeeper.

Call solr extract directory zkCli. sh to upload the configuration file

[root@node004 ~]# cd /root/solr-7.2.0/server/scripts/cloud-scripts/[root@node004 cloud-scripts]# lslog4j.properties  snapshotscli.sh  zkcli.bat  zkcli.sh[root@node004 cloud-scripts]# ./zkcli.sh -zkhost 192.168.178.161:2181,192.168.178.161:2182,192.168.178.161:2183  -cmd upconfig -confdir /usr/local/solrCloud/solr1/home/jonychen/conf/  -confname jonychen

Check whether the upload is successful

[Root @ node001 ~] #/Usr/local/zkCluster/zk1/bin/zkServer. sh status
ZooKeeper JMX enabled by default
Using config:/usr/local/zkCluster/zk1/bin/../conf/zoo. cfg
Mode: follower
[Root @ node001 ~] #/Usr/local/zkCluster/zk1/bin/zkCli. sh

If configs is available, the upload is successful.

[Zk: localhost: 2181 (CONNECTED) 1] quit
Quitting...

5. Start 4 tomcat

To view logs conveniently, copy the four windows and switch to their respective directories.

[Root @ node004 ~] # Cd/usr/local/solrCloud/solr1
[Root @ node004 solr1] # ls
Apache-tomcat-8.5.24 home logs
[Root @ node004 solr1] #./apache-tomcat-8.5.24/bin/startup. sh & tailf./apache-tomcat-8.5.24/logs/catalina. out

Startup successful page

 

6. Create a cluster

Create

Http: // 192.168.178.164: 6060/solr/admin/collections? Action = CREATE & name = jonychen & numShards = 2 & replicationFactor = 2

 

Delete

Http: // 192.168.178.164: 6060/solr/admin/collections? Action = DELETE & name = jonychen
