一、ElasticStack 技术栈
1、什么是ElasticStack 技术栈
ElasticsStak是elatic公司推出的一些列技术栈，早期有一个比较响亮的名字叫"ELK"用于日志采集系统，后续由于对该组件的扩充，引入很多新的组件，比如beats，xpack及云原生相关的组件，最终统称为elasticstack。
2、EFK 架构
3、ELFK 架构
3、ELFK 加价购升级
二、ElasticSearch集群部署
节点准备
ElasticStack
----> 2C 4G内存，磁盘50G+
elk91 10.0.0.91
elk92 10.0.0.92
elk93 10.0.0.93
1、ElaticSeach 的RPM的单点部署
1.1 下载Elcticsearch
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.17.5-x86_64.rpm
1.2 使用rpm包安装
rpm -ivh elasticsearch-7.17.5-x86_ 64.rpm
1.3 设置别名
#vim ~/.bashrc
...
alias yy=`egrep -v "^#|^$"`
#source ~/.bashrc alias yy='egrep -v "^#|^$"'
1. 4 修该配置文件
#yy /etc/elasticesearch/elaticsearch.yml
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 10.0.0.91
discovery.seed_hosts:["10.0.0.91"]
1.5 启动 elasticsearch 服务
systemctl enable --now elasticsearch
1.6 访问 elasticsearch 的 WebUI
curl http://10.0.0.91:9200/
2、Elasticsearch 的 rpm 集群部署
2.1 下载 Elastic search
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.17.5-x86_64.rpm
2.2 所有节点配置主机解析
cat >> /etc/hosts <<EOF
10.0.0.91 elk91
10.0.0.92 elk92
10.0.0.93 elk93
EOF
2.3 安装 elasticsearch
rpm -ivh elasticsearch-7.17.5-x86_64.rpm
2.4修改配置文件
# yy /etc/elasticsearch/elasticsearch.yml
cluster.name: oldboyedu-linux87
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
discovery.seed_hosts: ["elk91","elk92","elk93"]
cluster.initial_master_nodes: ["elk91","elk92","elk93"]
...
# scp /etc/elasticsearch/elasticsearch.yml elk92:/etc/elasticsearch/elasticsearch.yml
# scp /etc/elasticsearch/elasticsearch.yml elk93:/etc/elasticsearch/elasticsearch.yml
2.5 启动集群
# systemctl stop elasticsearch
systemctl enable --now elasticsearch
# systemctl restart elasticsearch
2.6 检查集群状态
# curl 10.0.0.91:9200/_cat/nodes
10.0.0.92 13 91 8 0.09 0.20 0.15 cdfhilmrstw - elk92
10.0.0.91 13 96 9 0.11 0.23 0.18 cdfhilmrstw * elk91
10.0.0.93 14 71 7 0.21 0.25 0.13 cdfhilmrstw - elk93
2.7 集群关机拍照
init 0
温馨提示:
如果你的集群不正常工作，执行如下操作
(1)集群所有节点停止服务
systemctl stop elasticsearch
pkill java
(2)确保停止服务完成，可以执行"ss -ntl"查看监听端口是否存在或者是查看java
ss -ntl
ps -ef | grep java
(3)删除集群默认的数据
rm -rf /var/lib/elasticsearch/* /var/log/elasticsearch/* /tmp/*
(4)重新启动集群即可
systemctl restart elasticsearch
