一、环境
系统:centos 6.5
JDK:1.8
Elasticsearch-5.2.2
Logstash-5.2.2
kibana-5.2.2
二、安装
1、安装JDK
下载JDK:http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
本环境下载的是64位tar.gz包,将安装包拷贝至安装服务器/usr/local目录
[root@server~]# cd /usr/local/
[root@localhost local]# tar -xzvf jdk-8u111-linux-x64.tar.gz
配置环境变量
[root@localhost local]# vim /etc/profile
将下面的内容添加至文件末尾(假如服务器需要多个JDK版本,为了ELK不影响其它系统,也可以将环境变量的内容稍后添加到ELK的启动脚本中)
JAVA_HOME=/usr/local/jdk1.8.0_111
JRE_HOME=/usr/local/jdk1.8.0_111/jre
CLASSPATH=.:$JAVA_HOME/lib:/dt.jar:$JAVA_HOME/lib/tools.jar
PATH=$PATH:$JAVA_HOME/bin
export JAVA_HOME
export JRE_HOME
ulimit -u 4096
[root@server local]# source /etc/profile
配置limit相关参数
[root@server local]# vim /etc/security/limits.conf
添加以下内容
* soft nproc 65536
* hard nproc 65536
* soft nofile 65536
* hard nofile 65536
[root@server local]# vim /etc/sysctl.conf
vm.max_map_count=262144
[root@server local]# sysctl –p (y)
创建运行ELK的用户
[root@server local]# groupadd elasticsearch
[root@server local]# useradd -g elasticsearch elasticsearch
[root@server local]# mkdir /opt/elk
[root@server local]# chown elasticsearch. /opt/elk -R
2、安装ELK
以下由elasticsearch用户操作
以elasticsearch用户登录服务器
[root@server ~]# su - elasticsearch
下载ELK安装包:https://www.elastic.co/downloads,并上传到服务器且解压,解压命令:tar -xzvf 包名
kibana5.2.2 下载地址:https://artifacts.elastic.co/downloads/kibana/kibana-5.2.2-linux-x86_64.tar.gz
elasticsearch 下载地址:https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.2.2.tar.gz
logstash下载地址:https://artifacts.elastic.co/downloads/logstash/logstash-5.2.2.tar.gz
配置Elasticsearch(单节点ES)
[root@server elk]# cd elasticsearch-5.2.2
[root@server elasticsearch-5.2.2]# vim config/elasticsearch.yml
添加:
network.host: 192.168.1.124
http.port: 9200
bootstrap.system_call_filter: false
http.cors.enabled: true
http.cors.allow-origin: "*"
action.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history*,logstash*
elasticsearch 默认启动会使用2g内存,如果自己测试需修改配置文件
[root@server elasticsearch-5.2.2]# vim config/jvm.options
-Xms2g --> 256m
-Xmx2g --> 256m
启动 elasticsearch
[root@server elasticsearch-5.2.2]# ./bin/elasticsearch -d
注: 启动完成后想看WEB端网页可以参考 以下网站安装head插件

安装logstash
[root@server logstash-5.2.2]# pwd
/opt/elk/logstash-5.2.2
[root@server logstash-5.2.2]# mkdir config.d
[root@server config.d]# vim nginx_accss.conf
input { file { path => [ "/usr/local/nginx/logs/access.log" ] start_position => "beginning" ignore_older => 0 type => "nginx-access" } } filter { if [type] == "nginx-access" { grok { match => [ "message","%{IPORHOST:clientip} %{NGUSER:ident} %{NGUSER:auth} \[%{HTTPDATE:timestamp}\] \"%{WORD:verb} %{URIPATHPARAM:request} HTTP/%{NUMBER:httpversion}\" %{NUMBER:response} (?:%{NUMBER:bytes}|-) %{QS:referrer} %{QS:agent} %{NOTSPACE:http_x_forwarded_for}" ] } urldecode { all_fields => true } date { locale => "en" match => ["timestamp" , "dd/MMM/YYYY:HH:mm:ss Z"] } geoip { source => "clientip" target => "geoip" database => "/opt/elk/logstash-5.2.2/data/GeoLite2-City.mmdb" add_field => [ "[geoip][coordinates]", "%{[geoip][longitude]}" ] add_field => [ "[geoip][coordinates]", "%{[geoip][latitude]}" ] } mutate { convert => [ "[geoip][coordinates]", "float" ] convert => [ "response","integer" ] convert => [ "bytes","integer" ] replace => { "type" => "nginx_access" } remove_field => "message" } } } output { elasticsearch { hosts => ["192.168.1.124:9200"] index => "logstash-nginx-access-%{+YYYY.MM.dd}" } stdout {codec => rubydebug} }
简单说明:
logstash的配置文件须包含三个内容:
input{}:此模块是负责收集日志,可以从文件读取、从redis /kafka读取或者开启端口让产生日志的业务系统直接写入到logstash
filter{}:此模块是负责过滤收集到的日志,并根据过滤后对日志定义显示字段
output{}:此模块是负责将过滤后的日志输出到elasticsearch或者文件、redis等
logstash配置及说明: ELK系统分析Nginx日志并对数据进行可视化展示
测试配置文件是否有问题:
/opt/elk/logstash-5.2.2/bin/logstash -t -f /opt/elk/logstash-5.2.2/config.d/nginx_accss.conf
启动 logstash:
nohup /opt/elk/logstash-5.2.2/bin/logstash -f /opt/elk/logstash-5.2.2/config.d/nginx_accss.conf &
查看是否启动成功
tail -f nohup.out
出现以上内容表示启动成功
安装kibana
保存退出
启动kibana
nohup ./bin/kibana &
其中 logstash-nginx-access- 从来的
代表实时收集的日志条数
