ELK 架构之 Elasticsearch、Kibana、Logstash 和 Filebeat 安装配置汇总（6.2.4 版本）

相关文章：

之前安装 ELK 的版本是 5.6.9，而且使用yum命令安装的，这边用最新版本 6.2.4 重新再安装一遍，不再使用yum命令安装，而是直接下载tar.gz包，解压执行命令运行。

ELK Stach 包地址：https://www.elastic.co/downloads/past-releases

1. Elasticsearch

之前 Elasticsearch 运行在 root 命令下，因为 Elasticsearch 运行会接受脚本，所以为了安全，正式环境要用非 root 账户进行运行。

创建用户组及用户：

[root@node1 ~]# groupadd es &&
useradd es -g es

切换到 es 用户：

[root@node1 ~]# su es

下载 Elasticsearch 包并解压：

[es@node1 ～]# cd /home/es
[es@node1 es]# wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.4.tar.gz
tar -zvxf elasticsearch-6.2.4.tar.gz

编辑配置文件：

[es@node1 es]# vi /home/es/elasticsearch-6.2.4/config/elasticsearch.yml

network.host: node1
http.port: 9200

启动 Elasticsearch：

[es@node1 es]# cd bin
[es@node1 es]# ./elasticsearch

出现下面错误：

[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]

解决方案，切换到 root 用户，并在/etc/security/limits.conf中添加配置：

[es@node1 es]# su root
[root@node1 ~]# vi /etc/security/limits.conf

* soft nofile 65536

* hard nofile 131072

* soft nproc 2048

* hard nproc 4096

然后切换到 es 用户，后台启动 Elasticsearch：

[es@node1 ~]# cd /home/es/elasticsearch-6.2.4/bin
[es@node1 es]# ./elasticsearch -d

查看 Elasticsearch 运行是否正常：

[es@node1 es]# curl http://node1:9200/
{
  "name" : "rK2jCU6",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "m6_Ijnd3Qki3HN20S-Bajg",
  "version" : {
    "number" : "6.2.4",
    "build_hash" : "ccec39f",
    "build_date" : "2018-04-12T20:37:28.497551Z",
    "build_snapshot" : false,
    "lucene_version" : "7.2.1",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

2. Kibana

下载 Kibana 包并解压：

[root@node1 ~]# mkdir software && cd software
[root@node1 software]# wget https://artifacts.elastic.co/downloads/kibana/kibana-6.2.4.tar.gz
[root@node1 software]# tar -zvxf kibana-6.2.4-linux-x86_64.tar.gz

编辑配置文件：

[root@node1 software]# vi /software/kibana-6.2.4-linux-x86_64/config/kibana.yml

# 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: "192.168.0.11"

# The Kibana server's name.  This is used for display purposes.
server.name: "kibana-server"

# The URL of the Elasticsearch instance to use for all your queries.
elasticsearch.url: "http://node1:9200"

后台运行 Kibana：

[root@node1 software]# cd /software/kibana-6.2.4-linux-x86_64/bin
[root@node1 software]# nohup ./kibana &

浏览器访问：http://node1:5601/

3. Logstash

下载 Logstash 包并解压：

[root@node1 software]# wget https://artifacts.elastic.co/downloads/logstash/logstash-6.2.4.tar.gz
[root@node1 software]# tar -zvxf logstash-6.2.4.tar.gz

创建logstash.conf配置文件：

[root@node1 software]# mkdir /software/logstash-6.2.4/conf.d
[root@node1 software]# vi /software/logstash-6.2.4/conf.d/logstash.conf

添加下面配置内容：

input {
 beats {
   port => 10515
  }
}
filter {
  if [fields][logtype] == "syslog" {
    grok {
      match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}" }
      add_field => [ "received_at", "%{@timestamp}" ]
      add_field => [ "received_from", "%{host}" ]
    }
    syslog_pri { }
    date {
      match => [ "syslog_timestamp", "MMM  d HH:mm:ss", "MMM dd HH:mm:ss" ]
    }
  }
  if [fields][logtype] == "spring-boot-log4j2" {
    json {
      source => "message"
      target => "data"
    }
  }
}
output {
  if [fields][logtype] == "spring-boot-log4j2"{
    elasticsearch {
      hosts => ["127.0.0.1:9200"]
      index => "spring-boot-log4j2-%{+YYYY.MM.dd}"
    }
  }

  if [fields][logtype] == "syslog"{
    elasticsearch {
      hosts => ["127.0.0.1:9200"]
      index => "filebeat-%{+YYYY.MM.dd}"
    }
  }
}

后台启动 Logstash：

[root@node1 software]# cd /software/logstash-6.2.4/bin
[root@node1 bin]# nohup ./logstash -f ../conf.d/logstash.conf &

查看端口是否被监听：

[root@node1 bin]# netstat -lntp |grep 10515
tcp6       0      0 :::10515                :::*                    LISTEN      28934/java

4. Filebeat

下载 Filebeat 包并解压：

[root@node1 software]# wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-6.2.4-linux-x86_64.tar.gz
[root@node1 software]# tar -zvxf filebeat-6.2.4-linux-x86_64.tar.gz

编辑配置文件：

[root@node1 software]# vi /software/filebeat-6.2.4-linux-x86_64/filebeat.yml

添加如下配置内容：

filebeat.prospectors:
- input_type: log
  paths:
    - /var/log/spring-boot-log4j2/*.log
  document_type: "spring-boot-log4j2" # 定义写入 ES 时的 _type 值
  multiline:
    #pattern: '^\s*(\d{4}|\d{2})\-(\d{2}|[a-zA-Z]{3})\-(\d{2}|\d{4})'   # 指定匹配的表达式（匹配以 2017-11-15 08:04:23:889 时间格式开头的字符串）
    pattern: '^\s*("{)'                         # 指定匹配的表达式（匹配以 "{ 开头的字符串）
    negate: true                                # 是否匹配到
    match: after                                # 合并到上一行的末尾
    max_lines: 1000                             # 最大的行数
    timeout: 30s                                # 如果在规定的时候没有新的日志事件就不等待后面的日志
  fields:
    logsource: node1
    logtype: spring-boot-log4j2

- input_type: log
  paths:
    - /var/log/messages
    #- /var/log/*.log
  document_type: "syslog" # 定义写入 ES 时的 _type 值
  fields:
    logsource: node1
    logtype: syslog

#output.elasticsearch:
  #hosts: ["node1:9200"]

output.logstash:
  hosts: ["node1:10515"]

后台启动 Filebeat：

[root@node1 software]# cd /software/filebeat-6.2.4-linux-x86_64
[root@node1 bin]# nohup ./filebeat -e -c filebeat.yml &
