linux-ELK安装配置

标签：ELK filebeat 7.13 config elasticsearch linux 安装 logstash es

前言：

ELK 是三个开源项目的首字母缩写，这三个项目分别是：Elasticsearch、Logstash 和 Kibana。

• Elasticsearch 是一个搜索和分析引擎。

• Logstash 是服务器端数据处理管道，能够同时从多个来源采集数据，转换数据，然后将数据发送到诸如 Elasticsearch 等存储库中。

• Kibana 则可以让用户在 Elasticsearch 中使用图形和图表对数据进行可视化。

filbeat是安装到web端的服务器进行日志采集

正式安装：

！！！！！！！！！！！注意好对应的版本！！！！！！！！！ (该教程使用的是7.13.2版本)

一.安装配置es(Elasticsearch)

由于一开始装的是7.10.2的所以截图中是7.10.2，版本不对应的话会出现版本冲突问题，后续统一调整为了7.13.2版本

创建es用户组：groupadd es
在es用户组下创建es用户：useradd es -g es -p es

进入es用户
[root@iZj6c49h0dw85252u6oxu0Z ~]# su es

下载安装包或者上传安装包
[es@iZj6c49h0dw85252u6oxu0Z data]$ wget https://artifacts.elastic.co/downloads/elasticsearch/eelasticsearch-7.13.2-linux-x86_64.tar.gz

解压
[es@iZj6c49h0dw85252u6oxu0Z data]$ tar -zxvf elasticsearch-7.13.2-linux-x86_64.tar.gz 

赋予用户权限：chown -R es:es /data/elasticsearch-7.13.2

启动es
[es@iZj6c49h0dw85252u6oxu0Z es]$ cd elasticsearch-7.13.2/
[es@iZj6c49h0dw85252u6oxu0Z elasticsearch-6.5.0]$ bin/elasticsearch -d

修改三个配置文件，文件中添加
export JAVA_HOME=/data/elasticsearch-7.13.2/jdk
export PATH=$JAVA_HOME/bin:$PATH

在/data/elasticsearch-7.13.2/config 中修改配置

服务器中验证  curl http://内网ip:9200

出现该画面就是按照配置成功启动了！

可以修改 /elasticsearch-7.13.2/config/jvm.options 文件
分配运行内存
-Xms4g
-Xmx4g

安装时遇到的问题：

错误问题

一
[root@izuf672oio5mc4fbyj0s0jz ~]# curl http://47.244.38.173:9200/
curl: (7) Failed connect to 47.244.38.173:9200; Connection refused

修改elasticsearch.yml文件，去掉注释并修改IP：network.host: 0.0.0.0，并开通入方向的阿里云访问规则，再次启动ES就可以了
[es@izuf672oio5mc4fbyj0s0jz elasticsearch-6.5.0]$ vi config/elasticsearch.yml 


二
[1] bootstrap checks failed
[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]

root用户下修改/etc/security/limits.conf
：su root
vim /etc/security/limits.conf

1.修改内容：
root soft nofile 65535
root hard nofile 65535
* soft nofile 65536
* hard nofile 65536

2.修改/etc/sysctl.conf
最后新增vm.max_map_count=655360
修改完成后，执行 sysctl -p 命令，使配置生效

二.安装配置Logstash

上传并解压
tar -zxvf logstash-7.13.2-linux-x86_64.tar.gz

解压完之后进入/config，拷贝一份logstash-sample.conf到bin目录下，方便后面启动：
cp /data/logstash-7.13.2/config/logstash-sample.conf /data/logstash-7.13.2/config/logstash.conf

编辑以下内容拷贝到bin的logstash.conf

# Sample Logstash configuration for creating a simple
# Beats -> Logstash -> Elasticsearch pipeline.

input {
  beats {
    port => 5044
  }
}

# log.file.path=/data/jars/logs/charge-server/charge-server-2023-08-29.5.log
# index => "%{[@metadata][beat]}}-%{+YYYY.MM.dd}"
# index => "%{[fields][log_type]}-%{+YYYY.MM.dd}"

output {
    elasticsearch {
      hosts => ["http://localhost:9200"]
      index => "%{[fields][log_type]}-%{+YYYY.MM.dd}"
      #user => "elastic"
      #password => "changeme"
  }
 
}

服务器后台启动
nohup bin/logstash -f config/logstash.conf > /dev/null 2>&1 &
    
应用命令启动（可实时看到启动日志）
bin/logstash -f config/logstash.conf

三.kibana安装与配置

上传并解压
tar -zxvf kibana-7.13.2-linux-x86_64.tar.gz

编辑/config/kibana.yml

这里用的是默认端口5601，这里serverhost不能用localhost，不然外网访问不到，在配置文件的最后一行，还可以将系统设置为中文。

kibana也不能使用root用户启动

# Kibana is served by a back end server. This setting specifies the port to use.
#server.port: 5601

# Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values.
# The default is 'localhost', which usually means remote machines will not be able to connect.
# To allow connections from remote users, set this parameter to a non-loopback address.
server.host: "0.0.0.0"


# Specifies locale to be used for all localizable strings, dates and number formats.
# Supported languages are the following: English - en , by default , Chinese - zh-CN .
i18n.locale: "zh-CN"

#es的hosts
elasticsearch.hosts: ["http://192.xxx.x.211:9200"]

cd kibana-7.13.2-linux-x86_64/bin/
    
启动    
./kibana --allow-root &
nohup ./kibana --allow-root &

日志路径
/data/ELK/kibana-7.13.2-linux-x86_64/config/node.options

四.filbeat安装与配置

上传并解压
tar -zxvf filebeat-7.13.2-linux-x86_64.tar.gz

编辑/filebeat-7.13.2-linux-x86_64/filebeat.yml

filebeat.inputs:

- type: log
  enabled: true
  paths:
    # 地址是服务的日志地址
    - /data/jars/logs/base-server/*.log
    #- c:\programdata\elasticsearch\logs\*
  fields:
    log_type: "base-server"

#多个服务就在后面追加
- type: log
  enabled: true
  paths:
    - /data/jars/logs/finance-server/*.log
    #- c:\programdata\elasticsearch\logs\*
  fields:
    log_type: "finance-server"
    

- type: filestream

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

  # Paths that should be crawled and fetched. Glob based paths.
  paths:
    - /var/log/*.log
    #- c:\programdata\elasticsearch\logs\*


# ============================== 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




# =================================== 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:


#日志是推送到Logstash,
# ------------------------------ Logstash Output -------------------------------
output.logstash:
  #The Logstash hosts
  #配置安装Logstash所在的服务器ip
  hosts: ["127.0.0.1:5044"]

  # 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 =================================
processors:
  - add_host_metadata:
      when.not.contains.tags: forwarded
  - add_cloud_metadata: ~
  - add_docker_metadata: ~
  - add_kubernetes_metadata: ~

启动运行
nohup ./filebeat -e -c filebeat.yml > /dev/null 2>&1 &
./filebeat -e -c filebeat.yml

遇到的问题:

不定时间，filebeat就会自动退出或者ssh连接断开filebeat自动退出

1后台启动
`nohup ./filebeat -e -c filebeat.yml > /dev/null 2>&1 &`

2不要直接关闭终端，而是先执行命令exit后

3关闭shh连接终端

最后 ip:5601访问kibana 至此安装完毕！
