(1) 解压
zookeeper 安装包

tar -zxvf zookeeper-3.4.6.tar.gz

(2)创建data和logs目录

创建目录并赋于写权限

指定zookeeper的数据存放目录和日志目录

(3)拷贝zookeeper
配制文件zoo_sample.cfg，文件在conf目录下

拷贝zookeeper配制文件zoo_sample.cfg并重命名zoo.cfg

(4) 修改zoo.cfg
zoo.cfg配制完后如下:

 

# The number of milliseconds of each tick

tickTime=2000

# The number of ticks that the initial

# synchronization phase can take

initLimit=10

# The number of ticks that can pass between

# sending a request and getting an acknowledgement

syncLimit=5

# the directory where the snapshot is stored.

# do not use /tmp for storage, /tmp here is just

# example sakes.

dataDir=/usr/local/zookeeper/data

dataLogDir=/usr/local/zookeeper/logs

# the port at which the clients will connect

clientPort=2181

# the maximum number of client connections.

# increase this if you need to handle more clients

#maxClientCnxns=60

#

# Be sure to read the maintenance section of the

# administrator guide before turning on autopurge.

#

# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance

#

# The number of snapshots to retain in dataDir

#autopurge.snapRetainCount=3

# Purge task interval in hours

# Set to "0" to disable auto purge feature

#autopurge.purgeInterval=1

server.1=192.168.98.202:2888:3888

server.2=192.168.98.203:2888:3888

server.3=192.168.98.204:2888:3888

 

(5)进入data
文件夹建立对应的myid文件

(6)拷贝zookeeper

文件夹到其他机器

 

3：配置solr（各个solr节点一样）(单节点)

(1) 将solr-6.0.0\server\solr-webapp目录下的webapp文件夹拷贝到tomcat8下webapps下，并改名为solr。

(2) 修改apache-tomcat-9.0.0.M4\webapps\solr\WEB-INF目录下的web.xml文件修改指定solrhome的位置

(3) 把solr目录下的server/sole复制到solrhome

cp -r /home/hadoop/app/solr-6.0.0/server/solr ~/data/solrhome

(4) 在solrhome下创建solrcore，复制solr-6.0.0/example/example-DIH/solr文件生成solrcore

cp -r ~/app/solr-6.0.0/server/solr/configsets/sample_techproducts_configs ~/data/solrhome/core1

(5) 将solr-6.0.0\server\lib\ext目录下的所有jar包拷贝到tomcat -> webapps -> solr -> WEB-INF -> lib

cp ~/app/solr-6.0.0/server/lib/ext/* ~/app/apache-tomcat-9.0.0.M4/webapps/solr/WEB-INF/lib

(6)将solr-6.0.0\server\resources目录下的log4j.properties文件拷贝到apache-tomcat\webapps\solr\WEB-INF\classes下,classes文件不存在则创建一个

mkdir ~/app/apache-tomcat-9.0.0.M4/webapps/solr/WEB-INF/classes

cp ~/app/solr-6.0.0/server/resources/log4j.properties ~/app/apache-tomcat-9.0.0.M4/webapps/solr/WEB-INF/classes

(7) 启动tomcat，访问solr

app/apache-tomcat-9.0.0.M4/bin/startup.sh

http://192.168.98.201:8080/solr/index.html#/

4：配置solr服务

(1) 在solr下，上传相关信息至zookeeper

在/home/hadoop/app/solr-6.0.0/server/scripts/cloud-scripts/目录下执行

./zkcli.sh -zkhost 192.168.98.202:2181,192.168.98.203:2181,192.168.98.204:2181 -cmd upconfig -confdir /home/hadoop/data/solrhome/core1/conf -confname myconf

(2) 每一台solr和zookeeper关联

修改每一台solr的tomcat 的 bin目录下catalina.sh文件中加入DzkHost指定zookeeper服务器地址：

 

在JAVA_OPTS添加zookeepre地址

JAVA_OPTS="-DzkHost=192.168.98.202:2181,192.168.98.203:2181,192.168.98.204:2181"

(3) 启动每一台solr服务器

(4) 查看tomcat日志

tail -f ~/app/apache-tomcat-9.0.0.M4/logs/catalina.out

在页面上会只看到一个节点是活的，查看文件知道，是使用了solr默认的8983端口

(5) 修改solr启动端口（各个节点的配置一样）

在solrhome下，有一个solr.xml文件，修改其中的内容为：

${host:192.168.98.201}

${jetty.port:8080}
