docker系列-06.docker搭建ELK，集成filebeat客户端配置使用（二）
接上一篇docker系列-06.docker搭建ELK（一）。
本篇将就filebeat远程将日志文件中的内容远程写入elk服务器中的logstash配置和使用做详细说明。
1.在客户端中搭建filebeat
filebeat将会将客户端中的日志文件远程写入elk服务器中的logstash中，
Elasticsearch处理完这些日志后，提供给kibana搜索。如果有多台客户端的日志需要写入到elk的logstash中，每台客户端都需要安装filebeat
本人选择docker的搭建方式。
首先搜索filebeat的docker镜像：
[root@localhost logs]# docker search filebeat

这里选择的是prima/filebeat镜像
2.创建filebeat配置文件，filebeat.yml，放入到/home/filebeat/文件夹中，filebeat.yml配置文件如下：
###################### 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.
#
# You can find the full configuration reference here:
# https://www.elastic.co/guide/en/beats/filebeat/index.html
# For more available modules and options, please see the filebeat.reference.yml sample
# configuration file.
#=========================== Filebeat prospectors =============================
filebeat.prospectors:
# Each - is a prospector. Most options can be set at the prospector level, so
# you can use different prospectors for various configurations.
# Below are the prospector specific configurations.
- type: log
# Change to true to enable this prospector configuration.
enabled: true
# Paths that should be crawled and fetched. Glob based paths.
#配置filebeat要读取的log文件路径，有多个的话可以使用通配符或者多个paths节点配置
paths:
- /home/logs/*_all.log
#- c:\programdata\elasticsearch\logs\*
# Exclude lines. A list of regular expressions to match. It drops the lines that are
# matching any regular expression from the list.
#exclude_lines: ['^DBG']
# Include lines. A list of regular expressions to match. It exports the lines that are
# matching any regular expression from the list.
#include_lines: ['^ERR', '^WARN']
# Exclude files. A list of regular expressions to match. Filebeat drops the files that
# are matching any regular expression from the list. By default, no files are dropped.
#exclude_files: ['.gz$']
# Optional additional fields. These fields can be freely picked
# to add additional information to the crawled log files for filtering
#fields:
# level: debug
# review: 1
### Multiline options
# Mutiline 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 ===============================
#modules也没有使用到，暂时不知道怎么使用，本人也注释掉了
#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: 3
#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` CLI flag or 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"
#============================= 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 `:` .
#cloud.auth:
#================================ Outputs =====================================
# Configure what output to use when sending the data collected by the beat.
#-------------------------- Elasticsearch output ------------------------------
#本人没有使用elasticseach，注释掉了
#output.elasticsearch:
# Array of hosts to connect to.
# hosts: ["192.168.1.33:9200"]
# Optional protocol and basic auth credentials.
#protocol: "https"
#username: "elastic"
#password: "changeme"
#----------------------------- Logstash output --------------------------------
output.logstash:
# The Logstash hosts，elk服务器logstash开放的地址和端口，嫌使用ssl的方式太麻烦，内网使用，所以ssl的相关配置也注释掉了
hosts: ["192.168.1.33:5044"]
logging.metrics.enabled: false
# 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"
#================================ Logging =====================================
# Sets log level. The default log level is info.
# Available log levels are: critical, 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: ["*"]
3.因为没使用到上述的modules，为了使filebeat启动的时候不报错，在home文件夹下创建一个modules的空目录
至此，filebeat客户端的安装准备工作完毕。
4.切换到elk服务器，配置logstash端口接收部分：
1）执行以下命令，进入到elk容器内部
docker exec -it elk（本人elk的docker容器名字） /bin/bash2）修改logstash的input配置文件(也可以通过使用苏追究文件映射的方式来处理)
root@b15eb2b7fdbb:cd /etc/logstash/conf.d
root@b15eb2b7fdbb:cd vi 02-beats-input.conf将文件内容修改成以下内容即可：
client_inactivity_timeout为客户端连接超时时间，默认是5秒貌似。
input {
beats {
port => 5044
client_inactivity_timeout => 36000
}
}5.重启elk
docker restart elk6.切换到filebeat客户端机器，运行以下命令，启动filebeat docker容器
docker run --name filebeat -v /home/filebeat/filebeat.yml:/filebeat.yml -v /home/logs/:/home/logs/ -v /home/filebeat/module:/module --net=host prima/filebeat如果看到以下日志，则说明已经往elk里面发送日志信息了：
7.打开kibana，创建filebeat-*索引，
我这里已经创建好了，就不再创建了。
8.进入kibana搜索页面，查看效果：
至此，整个elk的搭建和客户端filebeat的搭建使用介绍完毕。
