elk、kafka、zookeeper 安装

1、elk解释


ELK分别是Elasticsearch、Logstash、Kibana三个开源框架缩写

Elasticsearch    开源分布式搜索引擎,提供存储、分析、搜索功能。特点:分布式、基于reasful风格、支持海量高并发的准实时搜索场景、稳定、可靠、快速、使用方便等。    接收搜集的海量结构化日志数据,并提供给kibana查询分析

Logstash    开源日志搜集、分析、过滤框架,支持多种数据输入输出方式。    用于收集日志,对日志进行过滤形成结构化数据,并转发到elasticsearch中

Kibana    开源日志报表系统,对elasticsearch以及logstash有良好的web页面支持。    对elasticsearch提供的数据进行分析展示



ELK经典架构

Logstash部署至服务主机,对各个服务的日志进行采集、过滤、推送。

Elasticsearch存储Logstash传送的结构化数据,提供给Kibana。

Kibana提供用户UIweb页面进行,数据展示和分析形成图表等



logs 指各种日志文件以及日志信息:windows,negix,tomcat,webserver等



由于Logstash消耗资源大,而服务器资源相当宝贵,所以引进另一个轻量级日志采集框架Beats,其中包含以下6种

Packetbeat    用于搜集网络流量数据

Heartbeat       用于运行时间监控

Filebeat    用于搜集文件数据

Winlogbeat    用于搜集winodws事件数据

Metricbeat    用于指标

Auditbeat    用于审计数据



高并发场景

由于logstash消耗性能,所以高并发场景容易遇到流量上的瓶颈,及时使用logstash集群也是如此,所以可以添加中间件进行日志缓存处理。由于logstash数据源具有多种方式,所有中间件也可以很多选择,常见的有kafka,redis


logback出现的业务数据可以通过写入redis或者kafka等中间件进行缓存,再通过合理限制流量阀值输送至logstash进行过滤

beats 如果是filebeat其日志若无实时性要求,可以通过控制log文件更新速度限制Beats传输日志流量



2、ELK搭建(非集群)


2.1、下载ELK(保持版本一致)

Elasticsearch    官网elasticsearch-6.3.0.tar

Kibana        官网kibana-6.3.0下载 linux64位

Logstash    官网logstash-6.3.0.tar

Filebeat    官网filebeat-6.3.0 linux64位


环境:centos7.5系统

ip地址:192.168.0.91


通过rz命令上传安装包至centos7虚拟机home目录下



解压

cd /home

tar -zxvf elasticsearch-6.3.0.tar.gz          
tar -zxvf kibana-6.3.0-linux-x86_64.tar.gz
tar -zxvf filebeat-6.3.0-linux-x86_64.tar.gz  
tar -zxvf logstash-6.3.0.tar.gz




2.2、java环境搭建 

请参照:https://www.cnblogs.com/effortsing/p/10012211.html

推荐使用jdk1.8jdk环境配置



2.3、安装elasticsearch

修改配置文件

vi /home/elasticsearch-6.3.0/config/elasticsearch.yml


# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 192.168.0.91           ##服务器ip地址,必须写成ip,默认的localhost是无法通过浏览器访问的,localhost意思是只能从本地访问
#
# Set a custom port for HTTP:
#
http.port: 9200                 ##服务端口
#
# For more information, consult the network module documentation.
#


创建elsearch用户

groupadd elsearch           
useradd elsearch -g elsearch -p elasticsearch
chown -R elsearch:elsearch  elasticsearch-6.3.0


修改系统配置文件限制

sed -i '$a\vm.max_map_count = 655360' /etc/sysctl.conf


修改安全限制配置文件

cat> /etc/security/limits.conf<<EOF

# End of file
elsearch       hard        nofile        65536 
elsearch       soft        nofile        65536
*              soft       nproc         4096
*              hard       nproc         4096 
EOF


重启linux系统,否则不生效

reboot



启动elasticsearch

su elsearch

/home/elasticsearch-6.3.0/bin/elasticsearch   #命令窗运行

/home/elasticsearch-6.3.0/bin/elasticsearch  -d  #后台线程运行

启动报错问题请参照:https://www.cnblogs.com/effortsing/p/10363107.html


说明:

等几分钟,启动比较慢

用后台来启动后就不用管了,等一会查看到elsearch端口后就可以按ctrl+c 停止了,端口会继续存在



关闭elasticsearch

ctrl+c                                   #命令窗关闭

ps -ef | grep elastic                    #后台线程关闭

kill -9 4442                             ##pid 4442为查处线程的pid 



查看elasticsearch端口

}


出现上面这个报错是正常的,因为还没有安装es的管理插件,es官方提供一个用于管理es的插件,可清晰直观看到es集群的状态,以及对集群的操作管理,



下面开始安装es管理插件


首先安装npm

下载网址:https://nodejs.org/dist/latest-v8.x/

rz node-v8.15.0-linux-x86.tar.xz


解压安装包

tar -xf /root/node-v8.15.0-linux-x86.tar.xz -C /usr/local/


重命名为node

cd /usr/local/

mv node-v8.15.0-linux-x86 node


添加环境变量

cat>> /etc/profile<<EOF
#set for nodejs
export NODE_HOME=/usr/local/node
export PATH=$NODE_HOME/bin:$PATH
EOF
source /etc/profile


必须重启系统

reboot


查看版本

node -v

缺少libstdc++.so.6库报错解决请参照:https://www.cnblogs.com/effortsing/p/10363921.html

npm -v


安装es的管理插件


下载 elasticsearch-head

mv elasticsearch-head /home/


下面所有操作需要进入elasticsearch-head文件目录

cd /home/elasticsearch-head/

安装grunt命令行工具grunt-cli

npm install -g grunt-cli


安装grunt及其插件

npm install grunt --save-dev

npm install grunt@latest
npm install grunt-cli@latest
npm install grunt-contrib-copy@latest
npm install grunt-contrib-concat@latest
npm install grunt-contrib-uglify@latest
npm install grunt-contrib-clean@latest
npm install grunt-contrib-watch@latest
npm install grunt-contrib-connect@latest
npm install grunt-contrib-jasmine@latest

安装最后这个插件时候会卡住不动,这个时候就已经可以启动elasticsearch-head,不用管它,ctrl+c停止即可

时间比较漫长,要等一会


查看安装版本情况 

grunt -version


修改head的连接地址

修改 http://localhost:9200 为 http://192.168.0.91:9200, 这是elasticsearch的地址

vi /home/elasticsearch-head/_site/app.js

(function( app, i18n ) {

        var ui = app.ns("ui");
        var services = app.ns("services");

        app.App = ui.AbstractWidget.extend({
                defaults: {
                        base_uri: null
                },
                init: function(parent) {
                        this._super();
                        this.prefs = services.Preferences.instance();
                        this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://192.168.0.91:9200";


修改服务器的监听地址


添加:hostname: 192.168.0.91, 这是grunt所在的地址

cp /home/elasticsearch-head/Gruntfile.js /home/elasticsearch-head/Gruntfile.js.bak

vi /home/elasticsearch-head/Gruntfile.js

                connect: {
                        server: {
                                options: {
                                        hostname: 192.168.0.91,
                                        port: 9100,
                                        base: '.',
                                        keepalive: true
                                }
                        }
                }

        });



修改elasticseach的配置文件elasticsearch.yml, 修改对应的ip以及跨域的设置,添加:

http.cors.enabled: true
http.cors.allow-origin: "*"

cat>> /home/elasticsearch-6.3.0/config/elasticsearch.yml<<EOF
http.cors.enabled: true
http.cors.allow-origin: "*"
EOF


重启es

kill -9 6104

su elsearch
/home/elasticsearch-6.3.0/bin/elasticsearch  -d 



启动head

cd /home/elasticsearch-head/

grunt server


测试

在浏览器输入 http://192.168.0.91:9100



连接elasticsearch

点击浏览器最上表栏里面的连接可以看到下面出现许多文字,表示连接成功





2.4、安装kibana


修改配置文件

vi /home/kibana-6.3.0-linux-x86_64/config/kibana.yml

server.port: 5601            ##服务端口
server.host: "192.168.0.91"     ##服务器ip  本机地址
 
elasticsearch.url: "http://192.168.0.91:9200"    ##elasticsearch服务地址 与elasticsearch对应



启动kibana

su elsearch

/home/kibana-6.3.0-linux-x86_64/bin/kibana       #命令窗启动

nohup /home/kibana-6.3.0-linux-x86_64/bin/kibana &   #后台线程启动

说明:

需要使用和启动elasticsearch同一个用户来启动,否则启动失败

启动有些慢,需要一分钟




查看kibana端口:5601

查看kibana进程

[elsearch@bogon root]$ ps -ef | grep kibana

elsearch   1638   1586  0 08:21 pts/1    00:00:00 grep --color=auto kibana



关闭kibana

ctrl+c                                   #命令窗关闭

ps -ef | grep kibana                     #后台线程关闭

kill -9 1586                             ##pid 4525 为查处线程的pid 



验证kibana启动

http://192.168.0.91:5601

出现图形界面表示成功




2.5、安装logstash

新建logback-es.conf配置文件

cat> /home/logstash-6.3.0/config/logback-es.conf<<EOF
input {
    tcp {
        port => 9601
        codec => json_lines      
    }
}
output {
        elasticsearch {
                hosts => "192.168.0.91:9200"
        }
        stdout { codec => rubydebug }
}
EOF


说明:

上述文件复制时必须去除多余空格,保持yml文件规范。


上面文件解释:


input {                                    ##input 输入源配置
    tcp {                                  ##使用tcp输入源      官网有详细文档
        port => 9601                       ##服务器监听端口9061 接受日志  默认ip localhost
        codec => json_lines                ##使用json解析日志    需要安装json解析插件
    }
} 
filter {                                  ##数据处理
}                                
output {                                   ##output 数据输出配置
        elasticsearch {                    ##使用elasticsearch接收
            hosts => "192.168.0.91:9200"   ##集群地址  多个用,隔开,这里不能写localhost,否则无法启动
        }
        stdout { codec => rubydebug}       ##输出到命令窗口
}



检查配置文件是否有语法错

/home/logstash-6.3.0/bin/logstash -f /home/logstash-6.3.0/config/logback-es.conf --config.test_and_exit

正确执行结果:
