Docker 部署ELK

1、下载镜像

这里我们使用elk集成镜像，地址：https://hub.docker.com/r/sebp/elk/tags

[root@centos-mq ~]# docker pull sebp/elk:660

注：660为elk版本

2、启动

[root@centos-mq ~]# echo "vm.max_map_count=262144" > /etc/sysctl.conf
[root@centos-mq ~]# sysctl -p
[root@centos-mq ~]# docker run -dit --name elk 
    -p 5601:5601 
    -p 9200:9200 
    -p 5044:5044 
    -v /opt/elk-data:/var/lib/elasticsearch 
    -v /etc/localtime:/etc/localtime 
    sebp/elk:660

说明：-p 指定映射端口，5601kibana访问，9200es端口，5044 logstash收集日志端口；-v 指定es数据目录

3、访问

启动后等待数据初始化后，浏览器输入：http://10.10.0.13:5601,可看到kibana web界面

4、文件目录

通过docker exec -it elk /bin/bash可进入容器中，具体各服务配置文件路径如下

 [root@centos-mq ~]# docker exec -it elk /bin/bash
  /etc/logstash/        ## logstash 配置文件路径
  /etc/elasticsearch/   ##es 配置文件路径
  /var/log/             ## 日志路径

 5、通过filebeat收集java

 filebeat部署，版本最好与elk一直，这里也选择6.6.0版本，filebeat部署在应用所在服务器，进行日志收集，日志样例；

　　a）下载安装

[root@centos-mq ~]# wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-6.6.0-x86_64.rpm
[root@centos-mq ~]# rpm -ivh filebeat-6.6.0-x86_64.rpm

 　b）配置收集java日志

[root@vanje-dev02 ~]# vim /etc/filebeat/filebeat.yml 
#=========================== Filebeat inputs ============================
filebeat.inputs:- type: log
  enabled: true
  paths:
    - /apps/oneJars/himalaya/logs/one.log     ## 日志路径
  tags: ["one-himalaya"]　　　　　　　　　　　　　## 标签，用于判断
  multiline.pattern: '^d{4}-d{2}-d{2}'　　 ## 匹配日志开头
  multiline.negate: true　　　　　　　　　　　　 ## 日志合并
  multiline.match: after

#-------------------------- Elasticsearch output ------------------------------
#output.elasticsearch:
  #hosts: ["localhost:9200"]      ## 注释 这里是配置采集的日志存放的方式，我们先经过logstash处理，所以这里注释

#----------------------------- Logstash output --------------------------------
output.logstash:
  hosts: ["10.10.0.13:5044"]   ## 采集日志输出到logstash，ip为logstash服务ip

## 启动filebeat

[root@vanje-dev02 ~]# systemctl restart filebeat

 　　c）logstash配置

以下配置只是收集"2019-06-19 14:34:23.261 [http-nio-8090-exec-7] INFO  com.one.api.user.controller.UserBacklogController - [李强]:获取待办数"格式日志，用来分析用户使用时间及姓名

## 定过滤指定日志，没用的日志我们这里不收集，正常是要收集所有，
vim /etc/logstash/conf.d/02-beats-input.conf
input {
  beats {
    port => 5044
  }
}
filter {
  #if "one-himalaya" in [tags] {
  if [message] =~ '获取待办数' {
    grok {
      patterns_dir => ["/etc/logstash/patterns"]
      match => {
        "message" => "%{DAYTIME:day}s*%{THREAD:thread}s%{LOGEVL:level}s*%{JAVACLASS:class}s*- [%{JAVALOGMESSAGE:logmessage}]:"
         }
    }
  }
}
output {
 # if "one-himalaya" in [tags] {
  if [message] =~ '获取待办数' {
    elasticsearch {
      hosts => ["172.16.223.55:9200"]
      index => "one-himalaya10-15-%{+YYYY.MM.dd}"
    }
  }
}

## 自定义匹配规则
vim /etc/logstash/patterns
DAYTIME d{4}-d{2}-d{2}sd{2}:d{2}:d{1,2}.d{1,4}
LOGEVL [a-zA-Z]{4}
NUM d{1}
THREAD [http-nio-d{4}-exec-d{1,3}]

## 重启logstash
/etc/init.d/logstash restart

说明：实际生产中，我们会对收集的日志做各种分析提取，需要灵活使用grok 正则匹配来提取自己想要的数据。 可以通过Kibana Dev Tools>>Grok Debugger工具进行调式，例如：

6、kibana查看日志

打开kibana web界面，跟据提示创建索引，即可看到已经收集的日志信息：day logmessage 这两个字段，为切割日志自定义的字段，这些字段跟据自己所需灵活定义，以区分切割的数据。
