一、环境及软件版本
# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core) # ll /software jdk-8u60-linux-x64.tar.gz elasticsearch-5.6.1.tar.gz filebeat-5.6.1-x86_64.rpm kafka_2.11-0.11.0.1.tgz kibana-5.6.1-linux-x86_64.tar.gz logstash-5.6.1.tar.gz zookeeper-3.4.10.tar.gz
二、架构描述
1、采集层-->日志生产：10.150.27.55
NGINX LOG： /data/log/nginx/
TOMCAT LOG： /opt/tomcat/apache-tomcat-8.0.26/logs/
2、数据处理、缓存层-->日志转发LOGSTASH：10.150.27.66
3、数据处理、缓存层-->日志缓存集群：10.150.27.66/10.150.27.65
KAFKA/ZOOKEEPER
4、检索、展示层-->日志提取及过滤LOGSTASH：10.150.27.65
5、检索、展示层-->日志搜索ELASTICSEARCH：10.150.27.65
6、检索、展示层-->日志展示KIBANA：10.150.27.65
详细系统架构图如下：
三、安装部署
0、系统初始化
# more /etc/security/limits.conf root soft nofile 655350 root hard nofile 655350 * soft nofile 655350 * hard nofile 655350 # ulimit -HSn 65530 # more /etc/sysctl.conf vm.max_map_count= 262144 # sysctl -p
1、JAVA环境
# tar xf jdk-8u60-linux-x64.tar.gz
# mv jdk1.8.0_60 /usr/local/
# more /etc/profile
export JAVA_HOME=/usr/local/jdk1.8.0_60
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
# source /etc/profile
解决后面出现的LOGSTASH启动缓慢问题：
修改文件$JAVA_HOME/jre/lib/security/java.security
设置参数securerandom.source=file:/dev/urandom
2、安装ELASTICSEARCH
切换到普通用户 su - king
$ tar xf elasticsearch-5.6.1.tar.gz $ cd elasticsearch-5.6.1
安装x-pack插件：
$ ./bin/elasticsearch-plugin install x-pack
按照需求调整内存占用参数：
$ grep -Ev "#|^$" ./config/jvm.options -Xms2g -Xmx2g -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+AlwaysPreTouch -server -Xss1m -Djava.awt.headless=true -Dfile.encoding=UTF-8 -Djna.nosys=true -Djdk.io.permissionsUseCanonicalPath=true -Dio.netty.noUnsafe=true -Dio.netty.noKeySetOptimization=true -Dio.netty.recycler.maxCapacityPerThread=0 -Dlog4j.shutdownHookEnabled=false -Dlog4j2.disable.jmx=true -Dlog4j.skipJansi=true -XX:+HeapDumpOnOutOfMemoryError
修改监听端口，允许外部系统远程访问：
$ grep -Ev "#|^$" ./config/elasticsearch.yml network.host: 10.150.27.65
启动ElasticSearch：
./bin/elasticsearch &
验证是否成功启动：
$ curl http://elastic:[email protected]:9200 { "name" : "Z2-xF9U", "cluster_name" : "elasticsearch", "cluster_uuid" : "CfPyniZDSv6zJV9ww0Ks5Q", "version" : { "number" : "5.6.1", "build_hash" : "667b497", "build_date" : "2017-09-14T19:22:05.189Z", "build_snapshot" : false, "lucene_version" : "6.6.1" }, "tagline" : "You Know, for Search" }
3、安装LOGSTASH（10.160.27.65）
切换成root用户
# tar xf logstash-5.6.1.tar.gz # cd logstash-5.6.1 # mkdir conf.d/
设置接收kafka输入，输出到elasticsearch。（kafka安装配置完成后再配置此处，提前将配置列出。）
# more ./conf.d/kafka.conf
input {
kafka {
bootstrap_servers => "10.150.27.66:9092,10.150.27.65:9092"
topics => ["ecplogs"]
}
}
output {
elasticsearch {
hosts => ["10.150.27.65:9200"]
user => "elastic"
password => "changeme"
index => "ecp-log-%{+YYYY.MM.dd}"
flush_size => 20000
idle_flush_time => 10
template_overwrite => true
}
}
启动Logstash：
# ./bin/logstash -f conf.d/kafka.conf &
4、安装KIBANA
# tar -xf kibana-5.6.1-linux-x86_64.tar.gz # cd kibana-5.6.1-linux-x86_64/ # ./bin/kibana-plugin install x-pack
设置Kibaba对外开放的IP和ElasticSearch的url
# grep -Ev "#|^$" ./config/kibana.yml server.host: "10.150.27.65" elasticsearch.url: "http://10.150.27.65:9200"
启动Kibana并验证：
# ./bin/kibana & http://10.150.27.65:5601 elastic/changeme
5、安装ZOOKEEPER集群
10.150.27.66：
# tar xf zookeeper-3.4.10.tar.gz -C /usr/local/ # cd /usr/local/zookeeper-3.4.10/config/ # cp zoo_sample.cfg zoo.cfg # grep -Ev "#|^$" zoo.cfg tickTime=2000 initLimit=10 syncLimit=5 dataDir=/usr/local/zookeeper-3.4.10/zookeeper clientPort=2181 server.1=10.150.27.66:12888:13888 server.2=10.150.27.65:12888:13888 # more ../zookeeper/myid 1
10.150.27.65：
# more ../zookeeper/myid 2
启动Zookeeper并验证：
# ../bin/zkServer.sh start # ../bin/zkServer.sh status ZooKeeper JMX enabled by default Using config: /usr/local/zookeeper-3.4.10/bin/../conf/zoo.cfg Mode: follower
6、安装KAFKA集群
10.150.27.66：
# tar xf kafka_2.11-0.11.0.1.tgz -C /usr/local/ # cd /usr/local/kafka_2.11-0.11.0.1/config/ # grep -Ev "#|^$" server.properties broker.id=1 port=9092 host.name=10.150.27.66 num.network.threads=3 num.io.threads=8 socket.send.buffer.bytes=102400 socket.receive.buffer.bytes=102400 socket.request.max.bytes=104857600 log.dirs=/usr/local/kafka-logs num.partitions=1 num.recovery.threads.per.data.dir=1 offsets.topic.replication.factor=1 transaction.state.log.replication.factor=1 transaction.state.log.min.isr=1 log.retention.hours=1 log.segment.bytes=1073741824 log.retention.check.interval.ms=300000 zookeeper.connect=10.150.27.66:2181,10.150.26.65:2181 default.replication.factor=2 zookeeper.connection.timeout.ms=6000 group.initial.rebalance.delay.ms=0
10.150.27.65：
# grep -Ev "#|^$" server.properties broker.id=2 host.name=10.150.27.65
启动并验证：
# ../bin/kafka-server-start.sh -daemon server.properties # ../bin/kafka-topics.sh --create --zookeeper 10.150.27.66:2181 --replication-factor 1 --partitions 2 --topic ecplogs # ../bin/kafka-console-producer.sh --broker-list 10.150.27.66:2181 --topic ecplogs # ../bin/kafka-console-consumer.sh --zookeeper 10.150.27.65:2181 --from-beginning --topic ecplogs
7、日志中转LOGSTASH安装
# pwd
/usr/local/logstash-5.6.1/conf.d
# more kafka.conf
input {
beats {
port => "5044"
}
}
output {
kafka {
bootstrap_servers => "10.150.27.66:9092,10.150.27.65:9092"
topic_id => "ecplogs"
}
}
8、FILEBEAT安装配置
# rpm -ivh filebeat-5.6.1-x86_64.rpm [root@appcan-t-app-4 ~]# grep -Ev "#|^$" /etc/filebeat/filebeat.yml filebeat.prospectors: - input_type: log paths: - /opt/tomcat/apache-tomcat-8.0.26/logs/* output.logstash: hosts: ["10.150.27.66:5044"]
至此，配置全部完成。

另：TOMCAT日志格式更改为json样式。
cd /opt/tomcat/apache-tomcat-8.0.26/conf/
more server.xml
