环境
- 操作系统
Ubuntu18.04或者CentOS7.6- ELK
elasticsearch-7.6.0-amd64.deb
filebeat-7.6.0-amd64.deb
kibana-7.6.0-amd64.deb
logstash-7.6.0.deb
logstash-7.6.0.zip- Java
安装过程
Ubuntu
代码语言：javascript复制wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.6.0-amd64.deb
sudo dpkg -i elasticsearch-7.6.0-amd64.deb
sudo /bin/systemctl enable elasticsearch.service
sudo systemctl start elasticsearch.serviceKibana和Filebeat和上面一样
Logstash dpkg安装失败所以使用zip解压，然后进如./bin目录下启动
CentOS
下载4个软件的压缩包解压，都是进入./bin目录下启动。
使用压缩包解压得到的kibana和elasticsearch不能运行在root权限下，需要新建非root用户，并将kibana和elasticsearch的拥有者改为新建用户。
Logstash 脚本配置
以收集nginx日志为例，在logstash的文件夹下新建pipelines.conf文件，填入下列内容：
代码语言：javascript复制input {
beats {
port => "5044"
}
}
# The filter part of this file is commented out to indicate that it is
# optional.
filter {
grok {
match => { "message" => "%{COMBINEDAPACHELOG}" }
}
geoip {
source => "clientip"
}
}
output {
elasticsearch {
hosts => [ "localhost:9200" ]
index => "nginx-access-%{ YYYY.MM.dd}"
}
}Filebeat脚本配置
同样以收集nginx日志为例：
代码语言：javascript复制###################### 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 inputs =============================
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/nginx/*.log
#- c:programdataelasticsearchlogs*
# 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
tags: ["nginx"]
#Second

# review: 1
#tags: ["ssh"]
### 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"]
# Optional protocol and basic auth credentials.
#protocol: "https"
#username: "elastic"
#password: "changeme"
#----------------------------- Logstash output --------------------------------
output.logstash:
# The Logstash hosts
hosts: ["localhost: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完成上述工作后就可以启动ELK了
外部访问
- 安装nginx
- 生成登陆密码
社区版kibana登陆时没有身份验证，为了保证服务器安全需要在nginx上设置身份认证。因此需要先生成用户名和密码
需要先安装apache的一个套件用于生成用户名密码
代码语言：javascript复制sudo apt-get install apache2-utils设置用户名和密码
代码语言：javascript复制sudo htpasswd -c /etc/nginx/passwd/kibana.passwd username之后会要求输入密码
3. 修改/etc/nginx/nginx.conf脚本
在http{}中加入下面代码：
代码语言：javascript复制server {
listen 你的PORT http2;
listen [::]:你的PORT http2;
server_name 你的IP;
root /usr/share/nginx/html;
access_log /var/log/nginx/kibana_access.log;
error_log /var/log/nginx/kibana_error.log;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
auth_basic "Kibana Auth";#由于我没有x-pack，所以在访问kibana时设置了身份认证，保证服务器安全
auth_basic_user_file /etc/nginx/passwd/kibana.passwd;
location / {
proxy_pass http://127.0.0.1:5601;#访问你的端口时，会自动代理到127.0.0.1的5601端口
}
}4. 重启nginx
代码语言：javascript复制systemctl restart nginx.service转载地址
