- Elasticsearch
Elasticsearch是一个实时的分布式搜索分析引擎， 它能让你以一个之前从未有过的速度和规模，去探索你的数据。它被用作全文检索、结构化搜索、分析以及这三个功能的组合2.Logstash
Logstash是一款强大的数据处理工具，它可以实现数据传输，格式处理，格式化输出，还有强大的插件功能，常用于日志处理。3.Kibana
kibana是一个开源和免费的工具，它可以为Logstash和ElasticSearch提供的日志分析友好的Web界面，可以帮助您汇总、分析和搜索重要数据日志。官网地址：https://www.elastic.co/cn/downloads/
注意：配置文件ip要根据实际情况修改
环境准备,三台Linux服务器，系统统一
elk-node1 192.168.3.181 数据、主节点（安装elasticsearch、logstash、kabana、filebeat）
elk-node2 192.168.3.182 数据节点（安装elasticsearch、filebeat)
elk-node3 192.168.3.183 数据节点（安装elasticsearch、filebeat）修改hosts文件每台hosts均相同
vim /etc/hosts
192.168.243.162 elk-node1
192.168.243.163 elk-node2安装jdk11,二进制安装
已安装java则略过此步骤
{{
cd /home/tools &&
wget https://download.java.net/java/GA/jdk11/13/GPL/openjdk-11.0.1_linux-x64_bin.tar.gz解压到指定目录
tar -xzvf jdk-11.0.4_linux-x64_bin.tar.gz -C /usr/local/jdk 配置环境变量（set java environment）
JAVA_HOME=/usr/local/jdk/jdk-11.0.1
CLASSPATH=$JAVA_HOME/lib/
PATH=$PATH:$JAVA_HOME/bin
export PATH JAVA_HOME CLASSPATH使环境变量生效
source /etc/profileyum源安装
yum -y install java
java -version }}
修改系统内核参数
调整最大虚拟内存映射空间
在末尾追加如下
vim /etc/sysctl.conf
vm.max_map_count=262144 在末尾追加如下
vim /etc/security/limit.conf
* soft nofile 1000000
* hard nofile 1000000
* soft nproc 1000000
* hard nproc 1000000
* soft memlock unlimited
* hard memlock unlimited
sysctl -pcd /etc/security/limits.d
vi 20-nproc.conf
-# Default limit for number of user's processes to prevent
-# accidental fork bombs.
-# See rhbz #432903 for reasoning.
* soft nproc 4096
root soft nproc unlimited
将*号改成用户名

#修改这两行
-Xms4g #设置最小堆的值为4g
-Xmx4g #设置组大堆的值为4g配置TLS和身份验证 -- 此步为了安全也可跳过该步
{{
在Elasticsearch主节点上配置TLS.
cd /usr/share/elasticsearch/
./bin/elasticsearch-certutil ca ##一直用enter键
./bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12
ll

-rw------- 1 root root 2527 Jun 28 16:43 elastic-stack-ca.p12#####给生产的文件添加elasticsearch组权限
chgrp elasticsearch /usr/share/elasticsearch/elastic-certificates.p12 /usr/share/elasticsearch/elastic-stack-ca.p12
#####给这两个文件赋640权限
chmod 640 /usr/share/elasticsearch/elastic-certificates.p12 /usr/share/elasticsearch/elastic-stack-ca.p12
######把这两个文件移动到elasticsearch配置文件夹中
mv /usr/share/elasticsearch/elastic-* /etc/elasticsearch/将tls身份验证文件拷贝到节点配置文件夹中
scp /etc/elasticsearch/elastic-certificates.p12 root@192.168.243.163:/etc/elasticsearch/
scp /etc/elasticsearch/elastic-stack-ca.p12 root@192.168.243.163:/etc/elasticsearch/}}
启动服务，验证集群
先启动主节点集群，在随后启动其他节点
systemctl start elasticsearch设置密码--统一设置密码为123456
/usr/share/elasticsearch/bin/elasticsearch-setup-passwords interactive验证集群--##浏览器访问
