docker安装elk7.6.0版本，配合filebeat收集日志

jdk版本用的是11

测试用了两台虚拟机，一台搭建elk，另外一台安装filebeat

我的测试java程序放到了gitee上面，其中的collector文件夹下有相应的程序  

https://gitee.com/guoanhao/Architect-Stage-Kafka.git

 

第一步 安装elk7.6.0（第一台机器）

docker pull sebp/elk:760

docker images

 

运行elk

1，运行之前，需要编辑两个文件

vi /etc/sysctl.conf

#添加如下代码
vm.max_map_count=262144

#刷新一下，否则不生效
sysctl -p 

 

第二个文件

vim /etc/security/limits.conf

添加以下内容，注意要添加在End of file之前，否则报错

* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096

　　

 

 

 

 

2，运行，设置一下ES_MIN_MEM和ES_MAX_MEM，因为我的虚拟机内存比较小。

docker run  -p 5601:5601 -p 9200:9200 -p 5044:5044 -itd  -e ES_MIN_MEM=128m -e ES_MAX_MEM=128m --name elk sebp/elk:760

 

# 查看elk日志，会输出很多信息，不太容易确定是否启动成功了。
# 等到日志信息不再增加了，说明启动好了
docker logs -f -t elk
# 通过docker ps命令查看，也不足以证明没有问题。

　　

怎么确定启动成功呢？访问一下下面的地址，出现页面就是启动成功了。

# elasticsearch地址
http://192.168.186.135:9200/
# kibana地址
http://192.168.186.135:5601/

# 或者这样检查elasticsearch
curl 127.0.0.1:9200

　　

 

 

 

 

 

启动后有可能报错，我们修改一些配置文件就可以了

 

# 进入容器
docker exec -it elk bash

# 进入目录
cd /etc/logstash/conf.d

# 编辑文件，将ssl相关的配置删除，如下图
vim 02-beats-input.conf 

# 退出容器，并且重启elk
exit
docker restart elk

 

 

 

 

 

 

 

第二步，搭建filebeat（第二台机器）

下载与elk相同版本的filebeat7.6.0，我在华为开源镜像站上下载的。上传到第二台服务器上（我放到了/home/software下）

# 也可以直接通过wget安装
wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-7.6.0-linux-x86_64.tar.gz

 

 

1. 解压到/usr/local目录下

tar -zxvf filebeat-7.6.0-linux-x86_64.tar.gz -C /usr/local/

2. 配置filebeat（filebeat.yml）

cd /usr/local/filebeat-7.6.0-linux-x86_64
vim filebeat.yml

配置信息如下

• 配置日志收集路径

• 关闭filebeat输出到elasticsearch

• 打开filebeat输出到logstash的配置（在logstash中配置输出到elasticsearch）

• 配置文件注意缩进

• 这里我用的filebeat是7.6版本，不同于6.0之前的，这里没有了document_type，我们使用fields:service:来代替，logstash配置文件也要相应的修改。

版本更新踩的坑： https://blog.51cto.com/kexiaoke/2092029

 

filebeat.inputs:

# Each - is an input. Most options can be set at the input level, so
# you can use different inputs for various configurations.
# Below are the input specific configurations.

- type: log

  # Change to true to enable this input configuration.
  enabled: true

  # Paths that should be crawled and fetched. Glob based paths.
  paths:
    # - /var/log/*.log
    - /home/software/logs/app-collector.log
    #- c:\programdata\elasticsearch\logs\*
  fields:
      service: app-log

- type: log
  enabled: true

  paths:
    - /home/software/logs/error-collector.log
    #- c:\programdata\elasticsearch\logs\*
  fields:
      service: error-log


# output.elasticsearch:
  # Array of hosts to connect to.
  # hosts: ["localhost:9200"]

output.logstash:
  # The Logstash hosts
  hosts: ["192.168.186.135:5044"]

配置文件中我们配置了两个- type: log，作用是将不同的log文件输出到logstash中，并且可以在logstash中通过fields:service: app-log或者fields:service: error-log确定是哪一个log，以便elasticsearch以不同的index输出。详见下面的logstash配置文件。

 

我的filebeat.yml如下

###################### Filebeat Configuration Example #########################

# This file is an example configuration file highlighting only the most common
# options. The filebeat.reference.yml file from the same directory contains all the
# supported options with more comments. You can use it as a reference.

  ### Multiline options

  # Multiline can be used for log messages spanning multiple lines. This is common
  # for Java Stack Traces or C-Line Continuation

  # The regexp Pattern that has to be matched. The example pattern matches all lines starting with [
  #multiline.pattern: ^\[

  # Defines if the pattern set under pattern should be negated or not. Default is false.
  #multiline.negate: false

  # Match can be set to "after" or "before". It is used to define if lines should be append to a pattern
  # that was (not) matched before or after or as long as a pattern is not matched based on negate.
  # Note: After is the equivalent to previous and before is the equivalent to to next in Logstash
  #multiline.match: after


#============================= Filebeat modules ===============================

filebeat.config.modules:
  # Glob pattern for configuration loading
  path: ${path.config}/modules.d/*.yml

  # Set to true to enable config reloading
  reload.enabled: false

  # Period on which files under path should be checked for changes
  #reload.period: 10s

#==================== Elasticsearch template setting ==========================

setup.template.settings:
  index.number_of_shards: 1
  #index.codec: best_compression
  #_source.enabled: false

#================================ General =====================================

# The name of the shipper that publishes the network data. It can be used to group
# all the transactions sent by a single shipper in the web interface.
#name:

# The tags of the shipper are included in their own field with each
# transaction published.
#tags: ["service-X", "web-tier"]

# Optional fields that you can specify to add additional information to the
# output.
#fields:
#  env: staging


#============================== Dashboards =====================================
# These settings control loading the sample dashboards to the Kibana index. Loading
# the dashboards is disabled by default and can be enabled either by setting the
# options here or by using the `setup` command.
#setup.dashboards.enabled: false

# The URL from where to download the dashboards archive. By default this URL
# has a value which is computed based on the Beat name and version. For released
# versions, this URL points to the dashboard archive on the artifacts.elastic.co
# website.
#setup.dashboards.url:

#============================== Kibana =====================================

# Starting with Beats version 6.0.0, the dashboards are loaded via the Kibana API.
# This requires a Kibana endpoint configuration.
setup.kibana:

  # Kibana Host
  # Scheme and port can be left out and will be set to the default (http and 5601)
  # In case you specify and additional path, the scheme is required: http://localhost:5601/path
  # IPv6 addresses should always be defined as: https://[2001:db8::1]:5601
  #host: "localhost:5601"

  # Kibana Space ID
  # ID of the Kibana Space into which the dashboards should be loaded. By default,
  # the Default Space will be used.
  #space.id:

#============================= Elastic Cloud ==================================

# These settings simplify using Filebeat with the Elastic Cloud (https://cloud.elastic.co/).

# The cloud.id setting overwrites the `output.elasticsearch.hosts` and
# `setup.kibana.host` options.
# You can find the `cloud.id` in the Elastic Cloud web UI.
#cloud.id:

# The cloud.auth setting overwrites the `output.elasticsearch.username` and
# `output.elasticsearch.password` settings. The format is `<user>:<pass>`.
#cloud.auth:

#================================ Outputs =====================================

# Configure what output to use when sending the data collected by the beat.

#-------------------------- Elasticsearch output ------------------------------
# output.elasticsearch:
  # Array of hosts to connect to.
  # hosts: ["localhost:9200"]

  # Protocol - either `http` (default) or `https`.
  #protocol: "https"

  # Authentication credentials - either API key or username/password.
  #api_key: "id:api_key"
  #username: "elastic"
  #password: "changeme"

#----------------------------- Logstash output --------------------------------
output.logstash:
  # The Logstash hosts
  hosts: ["192.168.186.135:5044"]

  # Optional SSL. By default is off.
  # List of root certificates for HTTPS server verifications
  #ssl.certificate_authorities: ["/etc/pki/root/ca.pem"]

  # Certificate for SSL client authentication
  #ssl.certificate: "/etc/pki/client/cert.pem"

  # Client Certificate Key
  #ssl.key: "/etc/pki/client/cert.key"

#================================ Processors =====================================

# Configure processors to enhance or manipulate events generated by the beat.

processors:
  - add_host_metadata: ~
  - add_cloud_metadata: ~
  - add_docker_metadata: ~
  - add_kubernetes_metadata: ~

#================================ Logging =====================================

# Sets log level. The default log level is info.
# Available log levels are: error, warning, info, debug
#logging.level: debug

# At debug level, you can selectively enable logging only for some components.
# To enable all selectors use ["*"]. Examples of other selectors are "beat",
# "publish", "service".
#logging.selectors: ["*"]

#============================== X-Pack Monitoring ===============================
# filebeat can export internal metrics to a central Elasticsearch monitoring
# cluster.  This requires xpack monitoring to be enabled in Elasticsearch.  The
# reporting is disabled by default.

# Set to true to enable the monitoring reporter.
#monitoring.enabled: false

# Sets the UUID of the Elasticsearch cluster under which monitoring data for this
# Filebeat instance will appear in the Stack Monitoring UI. If output.elasticsearch
# is enabled, the UUID is derived from the Elasticsearch cluster referenced by output.elasticsearch.
#monitoring.cluster_uuid:

# Uncomment to send the metrics to Elasticsearch. Most settings from the
# Elasticsearch output are accepted here as well.
# Note that the settings should point to your Elasticsearch *monitoring* cluster.
# Any setting that is not set is automatically inherited from the Elasticsearch
# output configuration, so if you have the Elasticsearch output configured such
# that it is pointing to your Elasticsearch monitoring cluster, you can simply
# uncomment the following line.
#monitoring.elasticsearch:

#================================= Migration ==================================

# This allows to enable 6.7 migration aliases
#migration.6_to_7.enabled: true

 

 

3.启动filebeat

# 进入filebeat目录
cd /usr/local/filebeat-7.6.0-linux-x86_64
# 运行filebeat
nohup ./filebeat -e -c filebeat.yml > filebeat.log &
# 查看运行状态
ps -ef |grep filebeat
# 关闭filebeat
kill -9 pid

 

 

第三步 配置logstash

我们使用docker启动的elk，所以得先进入elk容器然后再进行配置

# 进入容器
docker exec -it elk bash

#进入logstash配置文件目录
/etc/logstash/conf.d

#编辑02-beats-input.conf文件
vim 02-beats-input.conf

1. 修改配置文件，我的文件内容如下（注意缩进）

配置文件中的 index => "app-log-%{[fields][service]}-%{+YYYY.MM.dd}" 
可以改为 index => "%{[fields][service]}-%{+YYYY.MM.dd}"或者 index => "app-log-%{+YYYY.MM.dd}" 

input {
  beats {
    port => 5044
  }
}

filter {

  ## 时区转换
  ruby {
        code => "event.set('index_time',event.timestamp.time.localtime.strftime('%Y.%m.%d'))"
  }

  if "app-log" in [fields][service]{
    grok {
        ## 表达式
        match => ["message", "\[%{NOTSPACE:currentDateTime}\] \[%{NOTSPACE:level}\] \[%{NOTSPACE:thread-id}\] \[%{NOTSPACE:class}\] \[%{DATA:hostName}\] \[%{DATA:ip}\] \[%{DATA:applicationName}\] \[%{DATA:location}\] \[%{DATA:messageInfo}\] ## (\'\'|%{QUOTEDSTRING:throwable})"]
    }
  }

  if "error-log" in [fields][service]{
    grok {
        ## 表达式
        match => ["message", "\[%{NOTSPACE:currentDateTime}\] \[%{NOTSPACE:level}\] \[%{NOTSPACE:thread-id}\] \[%{NOTSPACE:class}\] \[%{DATA:hostName}\] \[%{DATA:ip}\] \[%{DATA:applicationName}\] \[%{DATA:location}\] \[%{DATA:messageInfo}\] ## (\'\'|%{QUOTEDSTRING:throwable})"]
    }
  }

}

# 输出到elasticsearch
output {
  if [fields][service] == "app-log" {
    elasticsearch {
      hosts => ["192.168.186.135:9200"]
      index => "%{[fields][service]}-%{index_time}"
    }
  }else if [fields][service] == "error-log" {
    elasticsearch {
      hosts => ["192.168.186.135:9200"]
      index => "error-log-%{[fields][service]}-%{+YYYY.MM.dd}"
    }
  }
}

2.重启elk

docker restart elk

 

3. 测试日志收集，我的测试程序放到了gitee上，需要将jar包放到/home/software文件加下启动（因为filebeat配置的收集日志的目录是/home/software/logs）

启动后生成logs文件夹

java -jar collector.jar 

 文件夹中有两个日志文件，一个是正常的log，一个是异常log

 

浏览器访问下面的路径，会在日志文件中写入相应的日志，filebeat会收集到里面的日志信息。

http://192.168.186.137:8001/index
http://192.168.186.137:8001/err

 

 打印出来的日志信息

 

日志可视化

浏览器访问kibana，点击management =》index Patterns=》create index pattern

http://192.168.186.135:5601/

 

 创建index pattern，名称要与logstash中配置文件的相匹配

 输入名称后，点击next

这里我选的是i don't want use the time Filter。也可以选另一个进行测试 。

选择后点击 Create Index Pattern。这样index pattern就创建好了。

 查看index Pattern中的日志信息，右侧就是日志信息

 可以进行搜索

另一个index Pattern，err-log-*在创建的时候我选择了@timestamp

这里会多出来一个时间选择，选择后会查询时间范围之内的日志信息

 

也可以选择currentDateTime

 

 我一般情况下选择这种，具体区别我忘记了

 

 

 

 

到此配置完成 。
