[大数据]Centos7 安装ELK7.x鲲鹏系统

1 引言

如果你正在寻找如何快速安装和配置ELK，那么恭喜你找对教程了。

这篇博文我们就来分享下如何在Centos7 鲲鹏服务器上搭建ELK 7.x 版本

2 开始之前

在开始搭建之前,我们首先需要先检查 ELK 对 自己服务器的操作系统以及 JDK 是否兼容。

点击查看ELK对操作系统是否兼容

点击查看ELK对JDK是否兼容信息列表

ELK 是Elasticsearch ,Logstash, Kibana 的简称缩写,主要专注于可视化日志分析和查询

Elastic Stack 主要包括三大部分，

海量数据存储和检索----- Elasticsearch 分布式存储和查询
可视化界面和图表生成----Kibana 可提供可视化界面和各种图表的生成。
数据采集-----可以用Logstash采集日志也可以使用FileBeat 采集日志。
所以ELK 不过是Elastic Stack 用法中日志分析栈的一部分罢了。

3.下载elk所需的4个压缩包

ES 的官方下载地址:?https://www.elastic.co/cn/downloads/elasticsearch

kibana的官方下载地址:?https://www.elastic.co/cn/downloads/kibana

Logstash 官方下载地址：https://www.elastic.co/cn/downloads/logstash

Filebeat官方下载地址：https://www.elastic.co/cn/downloads/logstash

首先进入linux文件夹 、usr/local/elk

使用curl 命令行下载ES,kibana,logstash,filebeat

curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.13.4-linux-aarch64.tar.gz;
curl -L -O https://artifacts.elastic.co/downloads/kibana/kibana-7.13.4-linux-aarch64.tar.gz;
curl -L -O https://artifacts.elastic.co/downloads/logstash/logstash-7.13.4-linux-aarch64.tar.gz;
curl -L -O https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-7.13.4-linux-arm64.tar.gz;

如果操作系统不支持curl命令也可以使用wget命令下载

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.13.4-linux-aarch64.tar.gz;
wget https://artifacts.elastic.co/downloads/kibana/kibana-7.13.4-linux-aarch64.tar.gz;
wget https://artifacts.elastic.co/downloads/logstash/logstash-7.13.4-linux-aarch64.tar.gz;
wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-7.13.4-linux-arm64.tar.gz;

4.安装es

4.1 解压ES

tar -xzvf?elasticsearch-7.13.4-linux-aarch64.tar.gz

?

cd elasticsearch-7.13.4

?4.2修改操作系统限制
在Centos7 Linux 操作系统中，默认单个进程可以打开的最多文件数是1024

但是ES 对操作系统有些特殊要求

要求操作系统单个进程可以打开的最大文件数最少要达到65535.
而且ES 将会使用很多线程,也需要修改下操作系统限制。
如果不配置就会报错如下所示：
?

bootstrap checks failed. You must address the points described in the following [3] lines before starting Elasticsearch.
bootstrap check failure [1] of [3]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]
bootstrap check failure [2] of [3]: max number of threads [3687] for user [elasticsearch] is too low, increase to at least [4096]
bootstrap check failure [3] of [3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

解决方案：

如果想检查当前操作系统支持单个进程可以打开的最多文件数输入如下命令即可：

ulimit -n

返回值如果没修改会显示1024

要修复bootstrap check failure [1] of [3]?和bootstrap check failure [2] of [3]错误

需要修改/etc/security/limits.conf

vi /etc/security/limits.conf

编辑内容如下：

* ? ? ? ? ? ? ? soft ? ?nofile ? ? ? ? ?65535
* ? ? ? ? ? ? ? hard ? ?nofile ? ? ? ? ?65535
* ? ? ? ? ? ? ? hard ? ?nproc ? ? ? ? ? 4096
* ? ? ? ? ? ? ? soft ? ?nproc ? ? ? ? ? 4096

如下是参考：

root soft nofile 65535
root hard nofile 65535
* soft nofile 65535
* hard nofile 65535
elastic soft memlock unlimited
elastic hard memlock unlimited
elastic soft nofile 65536
elastic hard nofile 65536

设置限制数量，第一列表示用户，* 表示所有用户
soft nproc ：单个用户可用的最大进程数量(超过会警告);
hard nproc：单个用户可用的最大进程数量(超过会报错);
soft nofile ：可打开的文件描述符的最大数(超过会警告);
hard nofile ：可打开的文件描述符的最大数(超过会报错);
原文链接：https://blog.csdn.net/zxljsbk/article/details/89153690
断开session 链接，重新登陆生效
要修复bootstrap check failure [3] of [3] 错误，需要修改/etc/sysctl.conf
?

vi /etc/sysctl.conf

编辑内容如下:

vm.max_map_count=262144

• vm.max_map_count?配置确保操作系统拥有足够多的虚拟内存
• 如果使用的是包管理器方式安装，那么不需要这个操作，默认会进行配置。

刷新配置立即生效

sysctl -p

4.3 创建ES 用户

除此之外，ES 7.x 开始不再允许以任何方式使用root 用户直接操作ES,因此需要创建一个非root 用户。

ES 7.x 之前支持通过命令参数强行允许使用root用户执行ES, 但为了安全性,ES7.x 不再允许。
如果想查看当前Linux 下的所有用户列表,可输入如下命令:
?

compgen -u

因此我们还需要创建一个叫做非root用户，比如我们新创建一个叫做elastic的用户

# 创建用户
adduser elastic

然后为elastic?用户创建登陆密码,至少需要八位

# 选择要修改密码的用户名称
passwd elastic

执行后会提示两次输入密码,比如我们设置密码为es611521
New Password: es611521
Retype new password: es611521

再然后将es文件夹的操作权限授予elastic用户

# 授予执行权限
chmod u+x  /usr/local/elk/elasticsearch-7.13.4/bin
# ES 文件夹权限授权给elastic 用户
chown -R elastic /usr/local/elk/
# 创建数据文件夹
mkdir -p /usr/local/elk/data/es
# 将ES数据存储文件夹权限授权给elastic用户
chown -R elastic /usr/local/elk/data/es
# 创建日志文件夹
# 将ES 日志存储文件夹权限授权给elastic用户
chown -R elastic /usr/local/elk/data/es

4.4?修改 elasticsearch.yml 配置文件

进入config 文件

• cd /usr/local/elk/elasticsearch-7.13.4/config
  

  编辑elasticsearch.yml

• vi elasticsearch.yml
  

  # ======================== Elasticsearch Configuration =========================
  #
  # NOTE: Elasticsearch comes with reasonable defaults for most settings.
  #       Before you set out to tweak and tune the configuration, make sure you
  #       understand what are you trying to accomplish and the consequences.
  #
  # The primary way of configuring a node is via this file. This template lists
  # the most important settings you may want to configure for a production cluster.
  #
  # Please consult the documentation for further information on configuration options:
  # https://www.elastic.co/guide/en/elasticsearch/reference/index.html
  #
  # ---------------------------------- Cluster -----------------------------------
  #
  # Use a descriptive name for your cluster:
  #集群名称
  cluster.name: my-es
  #
  # ------------------------------------ Node ------------------------------------
  #
  # Use a descriptive name for the node:
  #集群节点���称
  node.name: node-1
  # ES默认 只允许本地 127.0.0.1 和[::1] 访问
  # # 也可以设置成0.0.0.0 允许所有IP主机访问
  # # 如果不配置就默认认为是开发者模式，如果配置不正确会写入警告但是能正确运行
  # # 如果配置了就会认为进入了生产环境, 如果配置不正确就会升级为异常,ES无法正确启动。
  network.host: 0.0.0.0
  # Add custom attributes to the node:
  #
  #node.attr.rack: r1
  #
  # ----------------------------------- Paths ------------------------------------
  #
  # Path to directory where to store the data (separate multiple locations by comma):
  #设置数据存放路径,建议修改这个路径到ES的安装文件夹外面,避免ES升级误删掉这个文件夹
  path.data: /usr/local/elk/data/es
  #
  # Path to log files:
  #设置数据存放路径,建议修改这个路径到ES的安装文件夹外面,避免ES升级误删掉这个文件夹
  path.logs: /usr/local/elk/data/es
  # ----------------------------------- Memory -----------------------------------
  #
  # Lock the memory on startup:
  #
  #bootstrap.memory_lock: false
  #
  # Make sure that the heap size is set to about half the memory available
  # on the system and that the owner of the process is allowed to use this
  # limit.
  #
  # Elasticsearch performs poorly when the system is swapping the memory.
  #
  # ---------------------------------- Network -----------------------------------
  #
  # By default Elasticsearch is only accessible on localhost. Set a different
  # address here to expose this node on the network:
  #
  #network.host: 127.0.0.1
  #
  # By default Elasticsearch listens for HTTP traffic on the first free port it
  # finds starting at 9200. Set a specific HTTP port here:
  #默认ES节点端口9200，如果是伪集群（在一台服务器上搭建集群），需要修改
  http.port: 9200
  # For more information, consult the network module documentation.
  #
  # --------------------------------- Discovery ----------------------------------
  #
  # Pass an initial list of hosts to perform discovery when this node is started:
  # The default list of hosts is ["127.0.0.1", "[::1]"]
  #发现其他节点主机配置 这里配置的是ES所在服务器的公网IP地址
  discovery.seed_hosts: ["127.0.0.1"]
  #
  # Bootstrap the cluster using an initial set of master-eligible nodes:
  #哪些节点可以被选举为主节点配置
  cluster.initial_master_nodes: ["node-1"]
  #
  # For more information, consult the discovery and cluster formation module documentation.
  #
  # ---------------------------------- Various -----------------------------------
  #
  # Require explicit names when deleting indices:
  #
  #action.destructive_requires_name: true
  #配置密码登录，kabana相应的配置
  #xpack.security.enabled: true
  #xpack.license.self_generated.type: basic
  #xpack.security.transport.ssl.enabled: true

  ?启动Elasticsearch

• 最后切换用户登陆

• # 切换用户
  su elastic
  

  启动ES

• ./bin/elasticsearch

  
  后台启动ES

• /usr/local/elk/elasticsearch-7.13.4-1/bin/elasticsearch -d

  访问Elasticsearch

• http://127.0.0.1:9200/

• 执行成功后会返回类似下面的内容

• {
    "name": "node-1",
    "cluster_name": "my-es",
    "cluster_uuid": "M0PH3gmtRu2Ov0mlP6uZDA",
    "version": {

      "build_type": "tar",
      "build_hash": "78722783c38caa25a70982b5b042074cde5d3b3a",
      "build_date": "2021-03-18T06:17:15.410153305Z",
      "build_snapshot": false,
      "lucene_version": "8.8.0",
      "minimum_wire_compatibility_version": "6.8.0",
      "minimum_index_compatibility_version": "6.0.0-beta1"
    },
    "tagline": "You Know, for Search"
  }

测试下配置是否正确

/usr/local/elk/filebeat-7.13.4/filebeat test config -e -c /usr/local/elk/filebeat-7.13.4/filebeat.ym

启动filebeat

如果首次启动需要输入如下命令：

/usr/local/elk/filebeat-7.13.4/filebeat setup -e -c /usr/local/elk/filebeat-7.13.4/filebeat.yml 

以后启动需要输入如下命令：

/usr/local/elk/filebeat-7.13.4/filebeat -e -c /usr/local/elk/filebeat-7.13.4/filebeat.yml 

?

• 如果需要后台运行filebeat

• nohup /usr/local/elk/filebeat-7.13.4/filebeat -e -c /usr/local/elk/filebeat-7.13.4/filebeat.yml -d "Publish" & > nohup.out
  

  如果想停止filebeat,那么可以输入如下命令

• ps aux | grep filebeat
  

  把进程kill掉就可以

• 本篇完～

• 如果需要设置kibana跟elasticsearch密码，请往下看

• 修改es的配置文件：elasticsearch.yml，添加如下配置

• vim /usr/local/elk/elasticsearch-7.13.4/config/elasticsearch.yml

• 

  ?

• es的bin目录下，执行设置用户名和密码的命令

• cd /usr/local/elk/elasticsearch-7.13.4/bin/;
  ./elasticsearch-setup-passwords interactive;
  

  这里会设置六个账号的密码：elastic,apm_system,kibana,logstash_system,beats_system,remote_monitoring_user.

?

修改kibana的配置kibana.yml：

vim /usr/local/elk/kibana-7.13.4/config/kibana.yml

?

重启es和kibana?
