1.下载软件
[root@elk-1 ~]\# wget http://archive.apache.org/dist/zookeeper/zookeeper-3.4.14/zookeeper-3.4.14.tar.gz

2.解压并移动zookeeper
[root@elk-1 ~]\# tar xf soft/zookeeper-3.4.13.tar.gz -C /data/
[root@elk-1 ~]\# mv /data/zookeeper-3.4.13/ /data/zookeeper

3.创建数据目录和日志目录
[root@elk-1 ~]\# mkdir /data/zookeeper/{data,logs}

4.准备配置文件
[root@elk-1 ~]\# cd /data/zookeeper/conf
[root@elk-1 /data/zookeeper/conf]\# cp zoo_sample.cfg zoo.cfg
[root@elk-1 /data/zookeeper/conf]\# vim zoo.cfg 
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zookeeper/data
DataLogDir=/data/zookeeper/logs
clientPort=2181

server.1=192.168.81.210:2888:3888
server.2=192.168.81.220:2888:3888
server.3=192.168.81.230:2888:3888

1.下载软件
[root@elk-1 ~]\# wget http://archive.apache.org/dist/zookeeper/zookeeper-3.4.14/zookeeper-3.4.14.tar.gz

2.解压并移动zookeeper
[root@elk-1 ~]\# tar xf soft/zookeeper-3.4.13.tar.gz -C /data/
[root@elk-1 ~]\# mv /data/zookeeper-3.4.13/ /data/zookeeper

3.创建数据目录和日志目录
[root@elk-1 ~]\# mkdir /data/zookeeper/{data,logs}

4.准备配置文件
[root@elk-1 ~]\# cd /data/zookeeper/conf
[root@elk-1 /data/zookeeper/conf]\# cp zoo_sample.cfg zoo.cfg
[root@elk-1 /data/zookeeper/conf]\# vim zoo.cfg 
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zookeeper/data
DataLogDir=/data/zookeeper/logs
clientPort=2181

server.1=192.168.81.210:2888:3888
server.2=192.168.81.220:2888:3888
server.3=192.168.81.230:2888:3888

5.生成节点id文件
#节点id只能保护数字
[root@elk-1 /data/zookeeper]\# echo 1 > /data/zookeeper/data/myid

4.2.配置zookeeper-2节点

与zookeeper-1节点只有配置文件和节点id文件有点不同，其余全一样

[root@elk-2 /data/zookeeper/conf]\# cat zoo.cfg 
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zookeeper/data
DataLogDir=/data/zookeeper/logs
clientPort=2181

server.1=192.168.81.210:2888:3888
server.2=192.168.81.220:2888:3888
server.3=192.168.81.230:2888:3888

[root@elk-2 /data/zookeeper/conf]\# echo 2 > /data/zookeeper/data/myid

[root@elk-2 /data/zookeeper/conf]\# cat zoo.cfg 
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zookeeper/data
DataLogDir=/data/zookeeper/logs
clientPort=2181

server.1=192.168.81.210:2888:3888
server.2=192.168.81.220:2888:3888
server.3=192.168.81.230:2888:3888

[root@elk-2 /data/zookeeper/conf]\# echo 2 > /data/zookeeper/data/myid

4.3.配置zookeeper-3节点 

[root@elk-3 /data/zookeeper/conf]\# cat zoo.cfg 
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zookeeper/data
DataLogDir=/data/zookeeper/logs
clientPort=2181

server.1=192.168.81.210:2888:3888
server.2=192.168.81.220:2888:3888
server.3=192.168.81.230:2888:3888

[root@elk-3 /data/zookeeper/conf]\# echo 3 > /data/zookeeper/data/myid

[root@elk-3 /data/zookeeper/conf]\# cat zoo.cfg 
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zookeeper/data
DataLogDir=/data/zookeeper/logs
clientPort=2181

server.1=192.168.81.210:2888:3888
server.2=192.168.81.220:2888:3888
server.3=192.168.81.230:2888:3888

[root@elk-3 /data/zookeeper/conf]\# echo 3 > /data/zookeeper/data/myid

4.4.启动所有节点

zookeeper集群必须保证有两个节点存活，也就是说必须同时要启动两个节点，否则集群将启动不成功，因此要都修改好配置文件后，再统一启动

[root@elk-1 /data/zookeeper]\# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /data/zookeeper/bin/../conf/zoo.cfg
Mode: follower

[root@elk-2 /data/zookeeper]\# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /data/zookeeper/bin/../conf/zoo.cfg
Mode: follower

[root@elk-3 /data/zookeeper]\# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /data/zookeeper/bin/../conf/zoo.cfg
Mode: leader

[root@elk-1 /data/zookeeper]\# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /data/zookeeper/bin/../conf/zoo.cfg
Mode: follower

[root@elk-2 /data/zookeeper]\# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /data/zookeeper/bin/../conf/zoo.cfg
Mode: follower

[root@elk-3 /data/zookeeper]\# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /data/zookeeper/bin/../conf/zoo.cfg
Mode: leader

5.部署kafka

注意：不要使用kafka2.11版本，有严重的bug，filebeat无法写入数据到kafka集群，写入的协议版本不同，存在问题

5.1.配置kafka-1节点 

1.下载二进制包
[root@elk-1 ~]\# wget https://archive.apache.org/dist/kafka/2.0.0/kafka_2.11-2.0.0.tgz

zookeeper.connection.timeout.ms=60000
group.initial.rebalance.delay.ms=0

4.创建数据目录
[root@elk-3 ~]\# mkdir /data/kafka/data

1.下载二进制包
[root@elk-1 ~]\# wget https://archive.apache.org/dist/kafka/2.0.0/kafka_2.11-2.0.0.tgz

2.安装kafka
[root@elk-1 ~/soft]\# tar xf kafka_2.13-2.4.0.tgz -C /data/

[root@elk-1 ~]\# /data/kafka/bin/kafka-server-start -daemon /data/kafka/config/server.properties
[root@elk-2 ~]\# /data/kafka/bin/kafka-server-start -daemon /data/kafka/config/server.properties
[root@elk-3 ~]\# /data/kafka/bin/kafka-server-start -daemon /data/kafka/config/server.properties

[root@elk-1 ~]\# /data/kafka/bin/kafka-server-start -daemon /data/kafka/config/server.properties
[root@elk-2 ~]\# /data/kafka/bin/kafka-server-start -daemon /data/kafka/config/server.properties
[root@elk-3 ~]\# /data/kafka/bin/kafka-server-start -daemon /data/kafka/config/server.properties

6.测试kafka与zookeeper连接

kafka能够产生数据并消费，整个集群就可以使用了

1.创建一个topic
[root@elk-1 /data/kafka]\# ./bin/kafka-topics.sh --create --zookeeper 192.168.81.210:2181,192.168.81.220:2181,192.168.81.230:2181 --replication-factor 1 --partitions 1 --topic testpic
Created topic "testpic".

2.查看topic
[root@elk-1 /data/kafka]\# ./bin/kafka-topics.sh --list --zookeeper 192.168.81.210:2181,192.168.81.220:2181,192.168.81.230:2181
testpic

#删除一个topic
[root@elk-1 /data/kafka]\# ./bin/kafka-topics.sh --delete --zookeeper 192.168.81.210:2181  --topic testpic

8.3.启动logstash并观察日志 

[root@elk-3 ~]\# nphup /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/in_kafka_to_es.conf &

[root@elk-3 ~]\# nphup /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/in_kafka_to_es.conf &

观察日志的输出，已经从nginx-access、tomcat-cata topic中读取了数据并存到了es集群中 部署ELK+Kafka+Filebeat日志收集分析系统_tomcat_06

8.4.查看elasticsearch集群是否增加了对应的索引库

es集群已经生成了tomcat-cata以及nginx-access索引库

到此为止logstash已经成功从kafka集群读取到日志数据，然后传入到elasticsearch集群不同的索引库
