1、安装包导入到 /usr/local/ 文件夹下
2、依次解压到各自文件夹下
tar -zxvf elasticsearchxxxxxxx.tar.gz
tar -zxvf logstashxxxxxxx.tar.gz
tar -zxvf kibanaxxxxxxx.tar.gz
1、新建用户 es,密码: es123456
adduser es
passwd es
2、文件夹授权给es用户
chown es /usr/local/elasticsearch-8.4.1/ -R
3、修改配置文件
编辑 /etc/security/limits.conf
末尾追加:
* soft nofile 1048576
* hard nofile 1048576
es soft nofile 1048576
es hard nofile 1048576
es soft nproc 4096
es hard nproc 4096
编辑 /etc/sysctl.conf
末尾追加:
kernel.printk=5
vm.max_map_count=655360
4、执行如下语句,使上面配置生效
sysctl -p
5、进入config文件夹开始配置,编辑jvm.options:
vim /usr/local/elasticsearch/config/jvm.options
新增:
-Xms108m
-Xmx108m
6、切换到es用户,启动服务
su es
./bin/elasticsearch -d (-d 后台运行)
报错:
[2022-09-08T11:12:03,244][ERROR][o.e.b.Elasticsearch ] [localhost.localdomain] fatal exception while booting Elasticsearchjava.

See logs for more details.
ERROR: Elasticsearch did not exit normally - check the logs at /usr/local/elasticsearch-8.4.1/logs/elasticsearch.log
ERROR: Elasticsearch exited unexpectedly
log日志:
找不到 jdk/lib/tool.jar,查看文件夹下发现有tools.jar,没有tool.jar
解决方案:
把tools.jar复制一份,改名叫tool.jar
cp tools.jar tool.jar
7、重新启动
8、访问测试
输入 ip:9200,访问失败
原因:elasticsearch开启了安全认证,虽然start成功,但是访问ip:9200失败
解决方案:修改 config/elasticsearch.yml 配置文件
搜索 security,把两处 ture 改成 false
9、报错
[ERROR]fatal exception while booting Elasticsearchjava.lang.IllegalStateException:failed to obtain node locks,tried [/usr/local/elasticsearch-8.4.1/data];maybe these locations are not wirtable or multiple nodes were started on the same data path?
原因:因为上面已经用es用户启动了一次elasticsearch,故而本次启动失败
解决方案:
(1) 查进程
ps -ef | grep elastic
(2) 杀进程:把所有看到的占用的端口都杀死一遍
kill -9 xxxxx
10、启动服务,成功
11、访问测试,成功
12、启动ElasticHD
进入elasticsearch文件夹下,执行
./ElasticHD -p 0.0.0.0:9800
没有那个文件或目录
1、进入logstash文件夹
2、更改配置文件 config/logstash.yml
修改监听地址和端口
地址填本机,端口9600-9700
3、启动服务:
./bin/logstash -e ‘input {stdin{}} output{stdout{}}’
4、简单测试,成功
5、创建配置文件 logstash-sample.conf
input {
tcp{
mode => "server"
host => "0.0.0.0"
type => "elk1"
port => 9601
codec => json
}
tcp{
mode => "server"
host => "0.0.0.0"
type => "elk2"
port => 9602
codec => json
}
}
output {
if [type]=="elk1" {
elasticsearch {
action => "index"
hosts => "**.**.**.**:9200"
index => "elk1"
codec =>"json"
}
}
if [type]=="elk2" {
elasticsearch {
action => "index"
hosts => "**.**.**.**:9200"
index => "elk2"
codec =>"json"
}
}
}
6、后台启动logstash
nohup ./bin/logstash -f ./config/logstash-sample.conf &
7、测试,成功
浏览器输入 ip:9600
1、文件夹权限授权
chown es /usr/local/kibana-8.4.1/ -R
2、修改配置文件:config下的kibana.yml
server.port:5601
server.host:’0.0.0.0’
elasticsearch.hosts:[‘http://x.x.x.x:9200’]
3、切换用户,后台启动服务
nohup ./bin/kibana &
4、测试,成功
浏览器输入 ip:5601
