最新版solr7.2集群搭建详细步骤

集群：高可用，备份，数据可分片

需要运行4个tomcat

1、tomcat端口号（默认占用8005,8009,8080三个端口）

tomcat服务	占用端口
tomcat1	6005、6060、6009
tomcat2	7005、7070、7009
tomcat3	8005、8080、8009
tomcat4	9005、9090、9009

2、创建solr集群目录，将单节点的solr复制共计4份至该目录

创建目录

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

复制单节点

[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

注意：删除每个solrhome实例目录下的core.properties

[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、修改16个配置文件

　　3.1  solr中的配置文件

　　　　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中的配置文件

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、上传配置文件至zookeeper

调用solr解压目录zkCli.sh上传配置文件

[root@node004 ~]# cd /root/solr-7.2.0/server/scripts/cloud-scripts/
[root@node004 cloud-scripts]# ls
log4j.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/s
olrCloud/solr1/home/jonychen/conf/  -confname jonychen

查看是否上传成功

[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

有configs则说明上传成功

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

5、启动4个tomcat

为方便查看日志，复制四个窗口进行操作，分别切换到各自对应的目录

[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

启动成功界面

6、创建集群

创建

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

删除

http://192.168.178.164:6060/solr/admin/collections?action=DELETE&name=jonychen
