一、基础环境配置
1、环境准备
规划3个节点，其中1个作为主节点，2个作为数据节点：
2. 修改主机名(三台都修改)
[root@localhost ~]# hostnamectl set-hostname elk-1
[root@localhost ~]# bash
[root@elk-1 ~]#
- 配置hosts文件(三台都修改)
[root@elk-1 ~]# vi /etc/hosts
192.168.200.10 elk-1
192.168.200.40 elk-2
192.168.200.90 elk-3
[root@elk-1 ~]# ping elk-2

rtt min/avg/max/mdev = 0.650/0.784/0.990/0.125 ms
[root@elk-1 ~]# ping elk-3
- 安装JDK(三台都安装)
[root@elk-1 ~]# yum install -y java-1.8.0-openjdk java-1.8.0-openjdk-devel
[root@elk-1 ~]# java -version 检查jdk版本
openjdk version "1.8.0_65"
OpenJDK Runtime Environment (build 1.8.0_65-b17)
OpenJDK 64-Bit Server VM (build 25.65-b01, mixed mode)
[root@elk-1 ~]# rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
错误一
[root@elk-1 ~]# rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
curl: (6) Could not resolve host: artifacts.elastic.co; Unknown error
error: https://artifacts.elastic.co/GPG-KEY-elasticsearch: import read failed(2).
[root@elk-1 ~]# vi /etc/resolv.conf
# Generated by NetworkManager

错误二
[root@elk-2 ~]# rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
curl: (35) TCP connection reset by peer
error: https://artifacts.elastic.co/GPG-KEY-elasticsearch: import read failed(2).
更新curl
[root@elk-2 ~]# yum update curl
Updated:
curl.x86_64 0:7.29.0-59.el7_9.1
Dependency Updated:
libcurl.x86_64 0:7.29.0-59.el7_9.1 libssh2.x86_64 0:1.8.0-4.el7 nspr.x86_64 0:4.25.0-2.el7_9
nss.x86_64 0:3.53.1-3.el7_9 nss-pem.x86_64 0:1.0.3-7.el7 nss-softokn.x86_64 0:3.53.1-6.el7_9

nss-util.x86_64 0:3.53.1-1.el7_9
Complete!
错误三
[root@elk-2 ~]# rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
curl: (60) Peer's Certificate has expired.
More details here: http://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.
error: https://artifacts.elastic.co/GPG-KEY-elasticsearch: import read failed(2).
修改一下日期
[root@elk-2 ~]# date
Thu Nov 26 11:29:33 CST 2020
[root@elk-2 ~]# date -s "2021-02-21 14:22:30"

[root@elk-2 ~]# date

2、配置Elasticserach
elk-1节点：
配置文件：vi /etc/elasticsearch/elasticsearch.yml
# ---------------------------------- Cluster -----------------------------------
#cluster.name: my-application
cluster.name: elk
//配置es的集群名称，默认是elasticsearch，es会自动发现在同一网段下的es，如果在同一网段下有多个集群，就可以用这个属性来区分不同的集群
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
node.name: elk-1
//节点名，默认随机指定一个name列表中名字，该列表在es的jar包中config文件夹里name.txt文件中，其中有很多作者添加的有趣名字
node.master: true
//指定该节点是否有资格被选举成为node，默认是true，es是默认集群中的第一台机器为master，如果这台机挂了就会重新选举master。 其他两节点为false
node.data: false
//指定该节点是否存储索引数据，默认为true。其他两节点为true
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 192.168.0.1
network.host: 192.168.200.10
//设置绑定的ip地址，可以是ipv4或ipv6的，默认为0.0.0.0
http.port: 9200
//启动的es对外访问的http端口，默认9200
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /var/lib/elasticsearch
//索引数据存储位置(保持默认,不要开启注释)
#
# Path to log files:
#
path.logs: /var/log/elasticsearch
//设置日志文件的存储路径，默认是es根目录下的logs文件夹
# --------------------------------- Discovery ----------------------------------
discovery.zen.ping.unicast.hosts: ["elk-1", "elk-2","elk-3"]
//设置集群中master节点的初始列表，可以通过这些节点来自动发现新加入集群的节点
[root@elk-1 ~]# cat /etc/hosts

[root@elk-3 ~]# cat /etc/elasticsearch/elasticsearch.yml |grep -v ^# |grep -v ^$
cluster.name: ELK

- 启动服务
先关闭防火墙，再启动es （三个节点都需要)
[root@elk-2 ~]# systemctl stop firewalld.service && setenforce 0 && iptables -F
[root@elk-2 ~]# systemctl start elasticsearch
使用ps命令查看进程是否存在
[root@elk-1 ~]# ps -ef |grep elasticsearch

使用netstat命令查看是否端口启动
[root@elk-1 ~]# netstat -lntp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

tcp6 0 0 :::22 :::* LISTEN 1098/sshd
tcp6 0 0 ::1:25 :::* LISTEN 1471/master
有以上端口或者进程存在，证明es服务启动成功
- 检测集群状态
