ELK日志分析
1、下载lrzsc
[root@localhost ~]# hostnamectl set-hostname elk ##更改主机名
[root@localhost ~]# bash
[root@elk ~]# history yum isntall -y lrzsc
2、下载源包
https://www.elastic.co/downloads/past-releases/ ##下载网址
压缩成elfk.tar.gz压缩包，并加载到主机上
3、解压文件,下载elasticsearch、kibana、 logstash
[root@elk ~]# tar xf elfk.tar.gz
[root@elk ~]# cd /rpm
[root@elk ~]# ls
elasticsearch-7.1.1-x86_64.rpm filebeat-7.1.1-x86_64.rpm kibana-7.1.1-x86_64.rpm logstash-7.1.1.rpm
[root@elk ~]# yum localinstall elasticsearch-7.1.1-x86_64.rpm
[root@elk ~]# yum localinstall kibana-7.1.1-x86_64.rpm
[root@elk ~]# yum localinstall logstash-7.1.1.rpm
4、配置elasticsearch
[root@elk ~]# vim /etc/elasticsearch/elasticsearch.yml ##配置elasticsearch
找到Cluster定义
Elasticsearch 集群名称
node.name：elk 节点名称
找到 Memory
network：192.168.11.160 主机IP
http.port: 9200 HTTP端口
找到 Discovery
cluster.initial_master_nodes 集群初始主节点
[root@elk ~]# systemctl start elasticsearch.service ##启动程序
[root@elk kibana]# netstat -anptu | grep java ##查看程序
tcp6 0 0 192.168.11.160:9200 :::* LISTEN 48445/java
tcp6 0 0 192.168.11.160:9300 :::* LISTEN 48445/java
tcp6 0 0 192.168.11.160:9200 192.168.11.160:58732 ESTABLISHED 48445/java
tcp6 0 0 192.168.11.160:9200 192.168.11.160:58738 ESTABLISHED 48445/java
5、配种域名解析
[root@elk ~]# vim /etc/hosts ##配置域名解析
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.11.160 elk
6、配置kibana
[root@elk ~]# vim /etc/kibana/kibana.yml ##配置kibana
server.port:5601 打开服务器端口5601
server.host:192.168.11.160 服务器主机 （也可以为elk ，因为hosts已经配置）
sercer.name: elk 服务器名
elasticsearch.hosts: ["http://192.168.11.160:9200"] elasticsearch主机
kibana.index: ".kibana" kibana索引
i18n.locale: "zh-CN" 中文表达
[root@elk ~]# systemctl start kibana ##启动kibana
[root@elk ~]# netstat -anptu | grep 5601 ##查看kibana
tcp 0 0 192.168.11.160:5601 0.0.0.0:* LISTEN 57307/node
7、配置logstash
[root@elk ~]# cat /etc/logstash/logstash.yml ##查看logstash配置但不进行配置
[root@elk ~]# vim /etc/logstash/conf.d/pipline.conf ##创建pipline.conf配置文件进行如下配置
input { ## 使用 file 插件从文件中读取数据file { ##指定要读取的日志文件路径path => "/var/log/messages" ##设定首次运行时的起始读取位置start_position => "beginning" ##设定首次运行时的起始读取位置##"beginning" - 从头读取文件所有内容}}
output { ##输出部分：定义数据的去向elasticsearch { ##使用 elasticsearch 插件将数据发送到 Elasticsearchhosts => ["http://192.168.11.160:9200"] ##指定 Elasticsearch 集群的节点地址##支持多个节点地址，实现高可用index => "system-log-%{+YYYY.MM.dd}" ##定义索引名称模板，自动按日期创建索引}
stdout { ##同时输出到标准输出（控制台）codec => rubydebug ##指定输出格式为 rubydebug##rubydebug 格式会将数据以易读的 JSON 格式打印}}

8、进行测试
对logstash测试
[root@elk ~]# logstash -e 'input{ stdin{} }output { stdout{} }'
[INFO ] 2025-07-16 21:21:29.007 [Api Webserver] agent - Successfully started Logstash API endpoint {:port=>9600}
1

[root@elk conf.d]# logstash -e 'input{ stdin{} }output { elasticsearch{ hosts=>["192.168.11.160:9200"]}}'
[INFO ] 2025-07-16 20:11:13.660 [Api Webserver] agent - Successfully started Logstash API endpoint {:port=>9600}

}
...... ##不主动关闭一直刷新
对elasticsearch测试
[root@localhost ~]# curl 192.168.11.160:9200
{"name" : "elk","cluster_name" : "my-application","cluster_uuid" : "WzA4MSNsRV6vMYSgX5EePw","version" : {"number" : "7.1.1","build_flavor" : "default","build_type" : "rpm","build_hash" : "7a013de","build_date" : "2019-05-23T14:04:00.380842Z","build_snapshot" : false,"lucene_version" : "8.0.0","minimum_wire_compatibility_version" : "6.8.0","minimum_index_compatibility_version" : "6.0.0-beta1"},"tagline" : "You Know, for Search"
}
对kibana测试
http://192.168.11.160:5601
在进行如下操作时，会出先system-log索引 如下图
[root@elk conf.d]# logstash -e 'input{ stdin{} }output { elasticsearch{ hosts=>["192.168.11.160:9200"]}}'
查看到如上界面，kibana配置成功
