5.1. Zookeeper集群搭建
第一步：需要安装jdk环境。
第二步：把zookeeper的压缩包上传到服务器。
第三步：解压缩。
第四步：把zookeeper复制三份。
[root@localhost ~]# mkdir /usr/local/solr-cloud
[root@localhost ~]# cp -r zookeeper-3.4.6 /usr/local/solr-cloud/zookeeper01
[root@localhost ~]# cp -r zookeeper-3.4.6 /usr/local/solr-cloud/zookeeper02
[root@localhost ~]# cp -r zookeeper-3.4.6 /usr/local/solr-cloud/zookeeper03
第五步：在每个zookeeper目录下创建一个data目录。
第六步：在data目录下创建一个myid文件，文件名就叫做“myid”。内容就是每个实例的id。例如1、2、3
[root@localhost data]# echo 1 >> myid
[root@localhost data]# ll
total 4
-rw-r--r--. 1 root root 2 Apr 7 18:23 myid
[root@localhost data]# cat myid
1
第七步：修改配置文件。把conf目录下的zoo_sample.cfg文件改名为zoo.cfg
server.1=192.168.25.154:2881:3881
server.2=192.168.25.154:2882:3882
server.3=192.168.25.154:2883:3883
第八步：启动每个zookeeper实例。
启动bin/zkServer.sh start
5.2. Solr集群的搭建
第一步：创建四个tomcat实例。每个tomcat运行在不同的端口。8180、8280、8380、8480
第二步：部署solr的war包。把单机版的solr工程复制到集群中的tomcat中。
第三步：为每个solr实例创建一个对应的solrhome。使用单机版的solrhome复制四份。
第四步：需要修改solr的web.xml文件。把solrhome关联起来。
第五步：配置solrCloud相关的配置。每个solrhome下都有一个solr.xml，把其中的ip及端口号配置好。
第六步：让zookeeper统一管理配置文件。需要把solrhome/collection1/conf目录上传到zookeeper。上传任意solrhome中的配置文件即可。
使用工具上传配置文件：/root/solr-4.10.3/example/scripts/cloud-scripts/zkcli.sh
./zkcli.sh -zkhost 192.168.25.154:2181,192.168.25.154:2182,192.168.25.154:2183 -cmd upconfig -confdir /usr/local/solr-cloud/solrhome01/collection1/conf -confname myconf
到了这一步报错

P.S. zookeeper已经启动，两个从一个主，防火墙已关闭
