Solr 集群搭建，
zookeeper配置
1.下载zookeeper，解压
2.conf同级目录新建data, log两个文件夹
3.data中新建myid文件，内容分别存放server的名称（1，2，3）(对应zoo.zfg中的server.1,server.2,server.3)
4.进入conf文件夹，拷贝zoo.example.zfg文件为zoo.zfg
5.修改zoo.zfg文件：
dataDir=XXX/XXX/zookeeper-3.4.10/data
dataLogDir=XXX/XXX/zookeeper-3.4.8/log
clientPort=2181
server.1=zooserver01:2888:3888
server.2=zooserver02:2888:3888
server.3=zooserver03:2888:3888
solr配置
1.下载solr，解压
2.修改bin下的solr.ini.cmd
ZK_HOST="zooserver01:2181,zooserver02:2181,zooserver03:2181"
去掉 ZK_CLIENT_TIMEOUT 的注释
3.上传configset，进入下面目录：7.4/server/server/scripts/cloud-scripts，执行命令
./zkcli.sh -zkhost zooserver01:2181,zooserver02:2181,zooserver03:2181 -cmd upconfig -confdir 7.4/server/server/solr/configsets/default/conf -confname default
4.修改solr.xml, 进入目录:7.4/server/solr/solr.xml
host改为域名或IP
5.zookeeper集群操作上传的文件
进入zookeeper的bin下
./zkCli.sh 连接zookeeper集群
ls /configs/myconf 查看上传的配置文件
delete /configs/myconf/solrconfig.xml 删除文件
delete /configs/myconf 删除空文件夹
get /configs/myconf/solrconfig.xml 查看文件内容
rmr /configs/myconf 递归删除（慎重使用）
6.启动solr集群
进入 solr-5.5.3下
./bin/solr restart
7.操作collection
a.创建collection
http://192.168.17.142:8983/solr/admin/collections?action=CREATE&name=test&numShards=3&replicationFactor=3&maxShardsPerNode=3&collection.configName=myconf
b.删除
http://192.168.17.142:8983/solr/admin/collections?action=DELETE&name=test
c.重新加载
http://192.168.17.143:8983/solr/admin/collections?action=RELOAD&name=test
