ELFK日志分析系统之搭建ELF+Filebeaat+Zookeeper+Kafka
作者:mmseoamin日期:2024-04-30

引言

结合前面所学

http://ELK日志分析系统

一、为什么要做日志分析平台

随着业务量的增长,每天业务服务器将会产生上亿条的日志,单个日志文件达几个GB,这时我们发现用Linux自带工具,cat grep awk 分析越来越力不从心了,而且除了服务器日志,还有程序报错日志,分布在不同的服务器,查阅繁琐。

待解决的痛点:

  1. 大量不同种类的日志成为了运维人员的负担,不方便管理;
  2. 单个日志文件巨大,无法使用常用的文本工具分析,检索困难;
  3. 日志分布在多台不同的服务器上,业务一旦出现故障,需要一台台查看日志。

二、ELK+Filebeat+Zookeeper+Kafka架构

ELFK日志分析系统之搭建ELF+Filebeaat+Zookeeper+Kafka,第1张

整体的架构如上图所示

这个架构图从左到右,总共分为5层,每层实现的功能和含义分别介绍如下:

第一层、数据采集层

  • 数据采集层位于最左边的业务服务器集群上,在每个业务服务器上面安装了filebeat做日志收集,然后把采集到的原始日志发送到Kafka+zookeeper集群上。

    第二层、消息队列层

    • 原始日志发送到Kafka+zookeeper集群上后,会进行集中存储,此时,filbeat是消息的生产者,存储的消息可以随时被消费。

      第三层、数据分析层

      • Logstash作为消费者,会去Kafka+zookeeper集群节点实时拉取原始日志,然后将获取到的原始日志根据规则进行分析、清洗、过滤,最后将清洗好的日志转发至Elasticsearch集群。

        第四层、数据持久化存储

        • Elasticsearch集群在接收到logstash发送过来的数据后,执行写磁盘,建索引库等操作,最后将结构化的数据存储到Elasticsearch集群上。

          第五层、数据查询、展示层

          • Kibana是一个可视化的数据展示平台,当有数据检索请求时,它从Elasticsearch集群上读取数据,然后进行可视化出图和多维度分析。

            三、搭建ELK+Filebeat+Zookeeper+Kafka

            1、环境准备

            服务器ip地址节点名称安装组件
            192.168.10.100node1 Elasticsearch 、Kibana
            192.168.10.101node2Elasticsearch
            192.168.10.102logstashlogstash、Apache
            192.168.10.103filebeatfilebeat
            192.168.10.104zk+kfk1zookeeper、Kafka
            192.168.10.105zk+kfk2zookeeper、Kafka

             所有服务器关闭防火墙以及核心防护

            systemctl stop firewalld
            setenforce 0

            修改主机名

            ##第一台
            [root@localhost ~]#hostnamectl set-hostname node1
            [root@localhost ~]#bash
            ##第二台
            [root@localhost ~]#hostnamectl set-hostname node2
            [root@localhost ~]#bash
            ##第三台
            [root@localhost ~]#hostnamectl set-hostname logstash
            [root@localhost ~]#bash
            ##第四台
            [root@localhost ~]#hostnamectl set-hostname filebeat
            [root@localhost ~]#bash
            ##第五台
            [root@localhost ~]#hostnamectl set-hostname zk-kfk1
            [root@localhost ~]#bash
            ##第六台
            [root@localhost ~]#hostnamectl set-hostname zk-kfk2
            [root@localhost ~]#bash

            配置域名解析

            echo "192.168.10.100 node1" > /etc/hosts
            echo "192.168.10.101 node2" > /etc/hosts
            echo "192.168.10.102 logstash" > /etc/hosts
            echo "192.168.10.103 filebeat" > /etc/hosts
            echo "192.168.10.104 zk-kfk1" > /etc/hosts
            echo "192.168.10.105 zk-kfk2" > /etc/hosts

            查看java环境

            ##java -version
            openjdk version "1.8.0_131"
            OpenJDK Runtime Environment (build 1.8.0_131-b12)
            OpenJDK 64-Bit Server VM (build 25.131-b12, mixed mode)

            2、部署ElasticSearch(在node1、node2节点上)

            两台同时操作

            1.安装ElasticSearch的rpm包,并解压

            #上传elasticsearch-5.5.0.rpm到/opt目录下
            cd /opt
            rz -E
            rpm -ivh elasticsearch-5.5.0.rpm  ##解压

            2.加载服务系统并开启开机自启

            systemctl daemon-reload                   ##加载服务
            systemctl enable elasticsearch.service    ##设置开机自启服务

            3.修改ElasticSearch主配置文件

            [root@node1 opt]#cp /etc/elasticsearch/elasticsearch.yml /etc/elasticsearch/elasticsearch.yml.bak              ##先进性备份
            [root@node1 opt]#vim /etc/elasticsearch/elasticsearch.yml   ###修改elasticsearch主配置文件
             
            cluster.name: my-elk-cluster             ##第17行, 取消注释,指定集群名字
            node.name: node1                         ##第23行, 取消注释,指定节点名字:Node1节点为node1,Node2节点为node2
            path.data: /data/elk_data                ##第33行, 取消注释,指定数据存放路径
            path.logs: /var/log/elasticsearch/       ##第37行, 取消注释,指定日志存放路径
            bootstrap.memory_lock: false             ##第43行, 取消注释,改为在启动的时候不锁定内存
            network.host: 0.0.0.0                    ##第55行, 取消注释,设置监听地址,0.0.0.0代表所有地址
            http.port: 9200                          ##第59行, 取消注释,ES 服务的默认监听端口为9200
            discovery.zen.ping.unicast.hosts: ["node1", "node2"]       ##第68行, 集群发现通过单播实现,指定要发现的节点 node1、node2
             
            [root@node1 opt]#grep -v "^#" /etc/elasticsearch/elasticsearch.yml
            cluster.name: my-elk-cluster
            node.name: node1
            path.data: /data/elk_data
            path.logs: /var/log/elasticsearch/
            bootstrap.memory_lock: false
            network.host: 0.0.0.0
            http.port: 9200
            discovery.zen.ping.unicast.hosts: ["node1", "node2"]

            4.创建数据存放路径并授权,启动服务并查看端口是否开启

            mkdir -p /data/elk_data                                ##创建数据存放路径
            chown elasticsearch:elasticsearch  /data/elk_data/     ##给数据存放路径赋予权限
            systemctl start elasticsearch.service                  ##启动比较慢,需要等待
            netstat -natp | grep 9200                              ##过滤端口
            tcp6       0      0 :::9200                 :::*                    LISTEN      37606/java

            5.查看节点信息

            浏览器访问  http://192.168.10.100:9200  、 http://192.168.10.101:9200 查看节点 Node1、Node2 的信息。
             
            浏览器访问 http://192.168.10.100:9200/_cluster/health?pretty  、 http://192.168.10.101:9200/_cluster/health?pretty查看群集的健康情况,可以看到 status 值为 green(绿色), 表示节点健康运行。
             
            #使用上述方式查看群集的状态对用户并不友好,可以通过安装 Elasticsearch-head 插件,可以更方便地管理群集。
             
            绿色:健康  数据和副本 全都没有问题
            红色:数据都不完整
            黄色:数据完整,但副本有问题

            3、安装ElasticSearch-head插件(在node1节点上操作)

            1.编译安装node1

            #上传软件包 node-v8.2.1.tar.gz 到/opt
            yum install gcc gcc-c++ make -y
            cd /opt
            rz -E
            tar zxvf node-v8.2.1.tar.gz
            cd node-v8.2.1/
            ./configure
            make -j4 && make install

            2.安装phantomjs(前端框架)

            [root@node1 opt]#ls
            elasticsearch-5.5.0.rpm    kibana-5.5.1-x86_64.rpm  node-v8.2.1.tar.gz                    rh
            elasticsearch-head.tar.gz  node-v8.2.1              phantomjs-2.1.1-linux-x86_64.tar.bz2
            [root@node1 opt]#tar  jxf phantomjs-2.1.1-linux-x86_64.tar.bz2 -C /usr/local/src/
            [root@node1 opt]#cd /usr/local/src/phantomjs-2.1.1-linux-x86_64/bin/
            [root@node1 bin]#ls
            phantomjs
            [root@node1 bin]#cp phantomjs  /usr/local/bin/

            3.安装ElasticSearch-head数据可视化工具

            [root@node1 opt]#ls
            elasticsearch-5.5.0.rpm    kibana-5.5.1-x86_64.rpm  node-v8.2.1.tar.gz                    rh
            elasticsearch-head.tar.gz  node-v8.2.1              phantomjs-2.1.1-linux-x86_64.tar.bz2
            [root@node1 opt]#tar xf elasticsearch-head.tar.gz -C /usr/local/src/
            [root@node1 opt]#cd /usr/local/src/elasticsearch-head/
            [root@node1 elasticsearch-head]#ls
            Dockerfile                          Gruntfile.js       LICENCE       package-lock.json             README.textile  test
            Dockerfile-alpine                   grunt_fileSets.js  node_modules  plugin-descriptor.properties  _site
            elasticsearch-head.sublime-project  index.html         package.json  proxy                         src
            [root@node1 elasticsearch-head]#npm install
            npm WARN deprecated fsevents@1.2.13: The v1 package contains DANGEROUS / INSECURE binaries. Upgrade to safe fsevents v2
            npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules/karma/node_modules/chokidar/node_modules/fsevents):

            up to date in 5.63s

            4.修改ElasticSearch主配置文件

            [root@node1 opt]#vim /etc/elasticsearch/elasticsearch.yml      ##修改 Elasticsearch 主配置文件
             
            --末尾添加以下内容--
            http.cors.enabled: true				#开启跨域访问支持,默认为 false
            http.cors.allow-origin: "*"			#指定跨域访问允许的域名地址为所有
             
            systemctl restart elasticsearch     ##重启elasticsearch服务

            5.启动ElasticSearch-head服务

            #必须在解压后的 elasticsearch-head 目录下启动服务,进程会读取该目录下的 gruntfile.js 文件,否则可能启动失败。
            cd /usr/local/src/elasticsearch-head/
            npm run start &
             
            > elasticsearch-head@0.0.0 start /usr/local/src/elasticsearch-head
            > grunt server
             
            Running "connect:server" (connect) task
            Waiting forever...
            Started connect web server on http://localhost:9100
             
            #elasticsearch-head 监听的端口是 9100
            ss -natp |grep 9100

            6.通过ELasticSearch-head查看ElasticSearch信息

            通过浏览器访问 http://192.168.10.100:9100/ 地址并连接群集。
            如果看到群集健康值为 green 绿色,代表群集很健康。
            注意:有的时候显示未连接,这时将 localhost 改成 IP 地址即可

            7.插入索引

            #通过命令插入一个测试索引,索引为 index-demo,类型为 test。
            curl -X PUT 'localhost:9200/index-demo1/test/1?pretty&pretty' -H 'content-Type: application/json' -d '{"user":"zhangsan","mesg":"hello world"}'
             
            //输出结果如下:
            {
            "_index" : "index-demo",
            "_type" : "test",
            "_id" : "1",
            "_version" : 1,
            "result" : "created",
            "_shards" : {
            "total" : 2,
            "successful" : 2,
            "failed" : 0
            },
            "created" : true
            }

            8.浏览器查看索引信息

            浏览器访问 http://192.168.10.100:9100/ 查看索引信息,
            可以看见索引默认被分片5个,并且有一个副本。
            点击“数据浏览”,会发现在node1上创建的索引为 index-demo,类型为 test 的相关信息。

            4、ELK Logstash部署(在APache节点上操作)

            1.安装Apache服务(httpd)

            yum install httpd -y   ##安装Apache服务

            2.安装java环境

            [root@logstash opt]#java -version
            openjdk version "1.8.0_131"
            OpenJDK Runtime Environment (build 1.8.0_131-b12)
            OpenJDK 64-Bit Server VM (build 25.131-b12, mixed mode)

            3.安装Logstash

            [root@logstash ~]#cd /opt/
            [root@logstash opt]#rz -E
            rz waiting to receive.

            5.定义Logstash配置文件

            #修改 Logstash 配置文件,让其收集系统日志/var/log/messages,并将其输出到 elasticsearch 中。
            chmod +r /var/log/messages					#让 Logstash 可以读取日志
             
            vim /etc/logstash/conf.d/system.conf                #该文件需自行创建,文件名可自定义
            input {
                file{
                    path =>"/var/log/messages"						#指定要收集的日志的位置
                    type =>"system"									#自定义日志类型标识
                    start_position =>"beginning"					#表示从开始处收集
                }
            }
            output {
                elasticsearch {										#输出到 elasticsearch
                    hosts => [ "192.168.10.100:9200" ]	#指定 elasticsearch 服务器的地址和端口
                    index =>"system-%{+YYYY.MM.dd}"					#指定输出到 elasticsearch 的索引格式
                }
            }
             
            systemctl restart logstash

            5、ELK Kibana部署(在node1节点上操作)

            1.安装Kibana

            下载地址:https://www.elastic.co/cn/downloads/past-releases/kibana-5-5-1
            [root@node1 ~]#cd /opt/
            [root@node1 opt]#ls
            elasticsearch-5.5.0.rpm    kibana-5.5.1-x86_64.rpm  node-v8.2.1.tar.gz                    rh
            elasticsearch-head.tar.gz  node-v8.2.1              phantomjs-2.1.1-linux-x86_64.tar.bz2
            [root@node1 opt]#rpm -ivh kibana-5.5.1-x86_64.rpm 
            警告:kibana-5.5.1-x86_64.rpm: 头V4 RSA/SHA512 Signature, 密钥 ID d88e42b4: NOKEY
            准备中...                          ################################# [100%]
            正在升级/安装...
               1:kibana-5.5.1-1                   ################################# [100%]

            2.设置Kibana的主配置文件

            cp /etc/kibana/kibana.yml /etc/kibana/kibana.yml.bak ##给匹配值文件做备份
            vim /etc/kibana/kibana.yml                           ##设置 Kibana 的主配置文件
            ---------------------------------------------------------------------------------------------
            server.port: 5601                                    ##第2行, 取消注释,Kiabana 服务的默认监听端口为5601
            server.host: "0.0.0.0"                               ##第7行, 取消注释,设置 Kiabana 的监听地址,0.0.0.0代表所有地址
            elasticsearch.url: "http://192.168.10.100:9200"      ##第21行,取消注释,设置和 Elasticsearch 建立连接的地址和端口
            kibana.index: ".kibana"                              ##第30行,取消注释,设置在 elasticsearch 中添加.kibana索引

            3.启动Kibana服务

            [root@node1 opt]#systemctl start kibana.service 
            [root@node1 opt]#systemctl enable kibana.service 
            Created symlink from /etc/systemd/system/multi-user.target.wants/kibana.service to /etc/systemd/system/kibana.service.
            [root@node1 opt]#lsof -i:5601
            COMMAND  PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
            node    2332 kibana   11u  IPv4  32050      0t0  TCP *:esmagent (LISTEN)
            [root@node1 opt]#netstat -natp | grep 5601
            tcp        0      0 0.0.0.0:5601            0.0.0.0:*               LISTEN      2332/node

            4.验证Kibana

            5.将Apache服务器的日志(访问的、错误的)添加到ES并通过Kibana显示

            [root@logstash ~]#systemctl status httpd.service
            [root@logstash ~]#systemctl start httpd.service 
            [root@logstash ~]#systemctl status httpd.service
            [root@logstash conf.d]#vim /etc/logstash/conf.d/apache_log.conf
             
              file {
                path => "/etc/httpd/logs/access_log"
                type => "access"
                start_position => "beginning"
              } 
              file {
                path => "/etc/httpd/logs/error_log"
                type => "error"
                start_position => "beginning"
              } 
            } 
             
            output {
              if [type] == "access" {
                elasticsearch {
                  hosts => ["192.168.10.100:9200"]
                  index => "apache_access-%{+YYYY.MM.dd}"
                } 
              } 
              if [type] == "error" {
                elasticsearch {
                  hosts => ["192.168.10.100:9200"]
                  index => "apache_error-%{+YYYY.MM.dd}"
                } 
              } 
            } 
            cd /etc/logstash/conf.d/
            /usr/share/logstash/bin/logstash -f apache_log.conf
