docker部署solr+zk集群，
在三台服务器上搭建solr集群，具体架构如下所示：
192.168.184.127 solr1/zk1
192.168.184.128 solr2/zk2
192.168.184.129 solr3/zk3
1.安装docker
三台服务器上都执行以下命令
# setenforce 0
# systemctl stop firewalld
# systemctl disable firewalld
# sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
安装docker
# yum -y install docker
# systemctl start docker
# systemctl enable docker
2.安装zk集群,三台服务器上都执行以下命令
# mkdir -p /usr/local/solr-zk/zk/{conf,data,datalog}
solr1服务器执行：
# vim /usr/local/solr-zk/zk/conf/zoo.cfg
dataDir=/data
dataLogDir=/datalog
clientPort=2181
tickTime=2000
initLimit=5
syncLimit=2
autopurge.snapRetainCount=3
autopurge.purgeInterval=0
maxClientCnxns=60
standaloneEnabled=true
admin.enableServer=false
server.1=0.0.0.0:2888:3888
server.2=192.168.184.128:2888:3888
server.3=192.168.184.129:2888:3888
solr2服务器执行：
# vim /usr/local/solr-zk/zk/conf/zoo.cfg
dataDir=/data
dataLogDir=/datalog
clientPort=2181
tickTime=2000
initLimit=5
syncLimit=2
autopurge.snapRetainCount=3
autopurge.purgeInterval=0
maxClientCnxns=60
standaloneEnabled=true
admin.enableServer=false
server.1=192.168.184.127:2888:3888
server.2=0.0.0.0:2888:3888
server.3=192.168.184.129:2888:3888
solr3服务器执行：
# vim /usr/local/solr-zk/zk/conf/zoo.cfg
dataDir=/data
dataLogDir=/datalog
clientPort=2181
tickTime=2000
initLimit=5
syncLimit=2
autopurge.snapRetainCount=3
autopurge.purgeInterval=0
maxClientCnxns=60
standaloneEnabled=true
admin.enableServer=false
server.1=192.168.184.127:2888:3888
server.2=192.168.184.128:2888:3888
server.3=0.0.0.0:2888:3888
新建myid文件
192.168.184.127上执行
# echo "1" > /usr/local/solr-zk/zk/data/myid
192.168.184.128上执行
# echo "2" > /usr/local/solr-zk/zk/data/myid
192.168.184.129上执行
# echo "3" > /usr/local/solr-zk/zk/data/myid

# docker ps
访问solr集群：http://192.168.184.127:8983/solr/index.html
用命令创建cllocetion
curl 'http://127.0.0.1:8983/solr/admin/collections?action=CREATE&name=a&numShards=1&replicationFactor=3&maxShardsPerNode=1'
如下图所示，其他节点也会进行同步
