ELK收集windows服务器日志笔记

时间:2024-02-29 13:36:33

一、软件版本

  1.jdk-8u211-linux-x64.rpm

  2.elasticsearch-6.8.1.rpm

  3.logstash-6.8.1.rpm

  4.kibana-6.8.1-x86_64.rpm

  5.winlogbeat-6.8.4-windows-x86_64   在windows服务器安装配置

     说明:elasticsearch做集群   主机1:192.168.1.102 主机2:192.168.1.104

     logstash和kibana安装在主机1上

二、安装软件

  2.1 主机1和主机2:jdk-8u211-linux-x64.rpm和elasticsearch-6.8.1.rpm 并配置elasticsearch

    说明:elasticsearch依赖jdk环境,所以先安装jdk-8u211-linux-x64.rpm

    yum -y localinstall  jdk-8u211-linux-x64.rpm

            yum -y localinstall  elasticsearch-6.8.1.rpm

        

  创建数据目录和日志目录及权限修改
  [root@linux-elk1 ~]# mkdir -p /elk/{data,logs}
  [root@linux-elk1 ~]# chown elasticsearch.elasticsearch /elk/ -R

  修改内存限制,内存锁定需要进行配置需要2g以上内存,否则会导致无法启动elasticsearch。
  [root@linux-elk1 ~]# vim /usr/lib/systemd/system/elasticsearch.service
  在[Service]下加入下面这行内容
  LimitMEMLOCK=infinity

  [root@linux-elk1 ~]# vim /etc/elasticsearch/jvm.options
  -Xms2g
  -Xmx2g #最小和最大内存限制.

        编辑配置文件:vim /etc/elasticsearch/elasticsearch.yml 

  [root@logsystem src]# grep -v "^#" /etc/elasticsearch/elasticsearch.yml
  cluster.name: my-log
  node.name: node-1
  path.data: /elk/data
  path.logs: /elk/logs
  network.host: 192.168.1.102
  http.port: 9200
  discovery.zen.ping.unicast.hosts: ["192.168.1.102","192.168.1.104"]

  设置开机启动
  systemctl enable elasticsearch.service

  systemctl daemon-reload
  systemctl start elasticsearch.service

  查看状态
  systemctl status elasticsearch.service

  正在运行,查看端口
  ss -tnl

  

  查看信息,也是一种检测。若能出现如下信息,则说明配置正确
  curl http://192.168.1.102:9200

  

  

  集群有状态: green ,red , yellow
  绿色表示一切是好的(集群功能齐全)
  黄色意味着所有数据是可用的,但是一些副本尚未分配(集群功能齐全)
  红色意味着一些数据不可用
  即使一个集群是红色的,它仍然是部分功能(即它将继续搜索请求从服务可用的碎片)但是你可能需要尽快修复它,因为你有缺失的数据。

  Restful API:
  四类API
  1. 检查集群,节点,索引等健康与否,以及获取其相应状态
  2.管理集群,节点,索引及元数据
  3.执行CRUD操作
  4.执行高级操作,如paging ,filtering等


  ES访问接口:9200/tcp

  语法:
  curl -X<VERB> \'<PROTOCOL>://host:port/<PATH>?QUERY_STRING/\' -d \'<BODY>\'

  查看elasticsearch相关信息 json格式的
  [root@logsystem ~]# curl http://192.168.1.102:9200/_cluster/health?pretty=true
  {
  "cluster_name" : "elasticsearch",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 0,
  "active_shards" : 0,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0,
  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 100.0
  }

  [root@logsystem ~]# curl -X GET http://192.168.1.102:9200/_cat/nodes?v
  ip heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name
  192.168.1.102 7 95 1 0.00 0.01 0.05 mdi * node-1


  [root@logsystem ~]# curl -X GET http://192.168.1.102:9200/_cat/indices?help

  [root@logsystem ~]# curl -X GET \'http://192.168.1.102:9200/_cluster/state/version?pretty\'
  {
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "qKuBK9TlQ3G-Rj6IFAXzTQ",
  "version" : 16,
  "state_uuid" : "SzhdF4PvRIGFbwlI_PD_cg"
  }

  2.2主机1: logstash-6.8.1.rpm 并配置

   wget https://artifacts.elastic.co/downloads/logstash/logstash-6.8.1.rpm

   yum -y localinstall  logstash-6.8.1.rpm

  [root@logsystem ~]cd /etc/logstash/conf/

  vim system-log.conf 

  input{

    beats{
    add_field => {"myid"=>"windows_log"}
    port => 5044
  }
    beats {
    add_field => {"myid"=>"nginx_log"}
    port => 5400
    }
  stdin{}
  }

  output{
    if [myid] == "windows_log"{
      elasticsearch{
      hosts=>"192.168.1.102:9200"
      index=>"%{type}-%{+YYYY-MM-dd}"
      }
  }
  if [myid] == "nginx_log"{
      elasticsearch{
      hosts=>"192.168.1.102:9200"
      index=>"nginx_pj_log-%{+YYYY-MM-dd}"
      }
      }
  stdout{ codec=>rubydebug }
  }

  启动logstash:

    [root@logsystem src]# nohup logstash -f /etc/logstash/conf.d/server_log.conf & 

  测试配置文件是否有语法错误:
  [root@logsystem ~]logstash -f /etc/logstash/conf/system-log.conf

  数据类型
  Array: [item1,item2,...]
  Boolean: true,false
  Bytes:
  Codec: 编码器
  Hash: key=>value
  Number:
  Password:
  Path:文件系统路径
  String:字符串
  字段引用 []
  条件判断: == ,!=,<,>, in ,not in ,and,or ....


  常用imput Plugin
  imput插件:
  File :从指定的文件中读取事件流,按行来标记一个事件。
  使用FileWatch(Ruby开发)来监听文件是否变化; .sincedb保存文件的相关信息数据库中。

  [root@logsystem logstash]# rpm -ql logstash |grep "patterns" 查找pattern

      elasticsearch服务收到数据验证:

 

  2.3主机1:安装配置kibana   

  [root@logsystem src]# wget https://artifacts.elastic.co/downloads/kibana/kibana-6.8.1-x86_64.rpm
  安装
  [root@logsystem src]# yum localinstall kibana-6.8.1-x86_64.rpm -y 

  配置
  [root@logsystem src]# vim /etc/kibana/kibana.yml
  server.port: 5601 #监听端口
  server.host: "192.168.1.102" #监听地址
  elasticsearch.hosts: ["http://192.168.1.102:9200"] #elasticsearch服务器地址
  i18n.locale: "zh-CN" #修改中文

  [root@logsystem src]# systemctl start kibana
  [root@logsystem src]# systemctl enable kibana

    查看服务

 

     访问:http://192.168.1.102:5601

 

 

 

 

   2.4 收集服务器日志上安装winlogbeat-6.8.4-windows-x86_64

  解压到 C:\Program Files

  重新命名文件夹为winlogbeat
  用管理员身份打开windows的 powershell
  运行以下命令来安装服务
  PS C:\Users\Administrator> cd \'C:\Program Files\Winlogbeat\'
  PS C:\Program Files\Winlogbeat> .\install-service-winlogbeat.ps1

  不能安装时,令来关闭一些安全防护,输入命令后按Y确认
  PS C:\Program Files\Winlogbeat> set-executionpolicy remotesigned
  PS C:\Program Files\Winlogbeat> set-executionpolicy Bypass

     winlogbeat.yml 配置文件修改:

  winlogbeat.event_logs:
  - name: Application #应用程序事件;
  ignore_older: 8h #忽略8小时后的日志,初次启用传日志很有用;
  provider: #过虑源yml列表
  - Application Error
  - Application Hang
  - Windows Error Reporting
  - name: Security #安全日志
  ignore_older: 8h
  event_id: 4624, 4625, 4700-4800, -4735 #事件ID 匹配中事件ID发送
  - name: System #系统日志
  ignore_older: 8h

 

  检查配置语法
.  \winlogbeat.exe test config -c .\winlogbeat.yml -e

  启动winlogbeat
  C:\Program Files\Winlogbeat> Start-Service winlogbeat

  Windlogbeat基本配置 

  1.配置发送日志到logstash
  output.logstash:
  # The Logstash hosts
  hosts: ["10.10.10.10:5044"]
  2.配置发送日志到elasticsearch
  output.elasticsearch:
  hosts: ["10.10.10.10:9200"]
  template.name: "winlogbeat"
  template.path: "winlogbeat.template.json"
  template.overwrite: false

 

坑1:插件存放路径
报错:
org.elasticsearch.bootstrap.StartupException: java.lang.IllegalArgumentException: Property [elasticsearch.version] is missing for plugin [head]
        at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:125) ~[elasticsearch-5.2.2.jar:5.2.2]
        at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:112) ~[elasticsearch-5.2.2.jar:5.2.2]
        at org.elasticsearch.cli.SettingCommand.execute(SettingCommand.java:54) ~[elasticsearch-5.2.2.jar:5.2.2]
        at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:122) ~[elasticsearch-5.2.2.jar:5.2.2]
        at org.elasticsearch.cli.Command.main(Command.java:88) ~[elasticsearch-5.2.2.jar:5.2.2]
        at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:89) ~[elasticsearch-5.2.2.jar:5.2.2]
        at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:82) ~[elasticsearch-5.2.2.jar:5.2.2]

原因:新版本的elasticsearch不允许插件放入/usr/share/elasticsearch/plugins 目录下。(插件bigdesk,head ...)
解决:把插件移到其它目录即可
