ELK大家应该很了解了，废话不多说开始部署
kafka在其中作为消息队列解耦和让logstash高可用
kafka和zk 的安装可以参考这篇文章
深入理解Kafka3.6.0的核心概念，搭建与使用-CSDN博客
第一步、官网下载安装包
需要
elasticsearch-8.10.4
logstash-8.10.4
kibana-8.10.4
kafka_2.13-3.6.0
apache-zookeeper-3.9.1-bin.tar
filebeat-8.10.4-linux-x86_64.tar
第二步: 环境配置（每一台都做）
创建es用户
useradd es配置主机名、配置IP地址、每台主机配置/etc/hosts名称解析
192.168.1.1 es1
192.168.1.2 es2
192.168.1.3 es3
将Linux系统的软硬限制最大文件数改为65536，将所有用户的最大线程数修改为65536
打开/etc/security/limits.conf文件，添加以下配置（每一台都做）
vim /etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536
* soft nproc 65536
* hard nproc 65536
es hard core unlimited #打开生成Core文件
es soft core unlimited
es soft memlock unlimited #允许用户锁定内存
es hard memlock unlimited
soft xxx : 代表警告的设定，可以超过这个设定值，但是超过后会有警告。
hard xxx : 代表严格的设定，不允许超过这个设定的值。
nproc : 是操作系统级别对每个用户创建的进程数的限制
nofile : 是每个进程可以打开的文件数的限制
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);
修改/etc/sysctl.conf文件，添加下面这行，并执行命令sysctl -p使其生效
vim /etc/sysctl.conf
vm.max_map_count=262144 #限制一个进程可以拥有的VMA(虚拟内存区域)的数量，es要求最低65536
net.ipv4.tcp_retries2=5 #数据重传次数超过 tcp_retries2 会直接放弃重传，关闭 TCP 流
解压安装包，进入config文件夹，修改elasticsearch.yml 配置文件
cluster.name: elk #集群名称
node.name: node1 #节点名称
node.roles: [ master,data ] #节点角色
node.attr.rack: r1 #机架位置，一般没啥意义这个配置
path.data: /data/esdata
path.logs: /data/eslog
bootstrap.memory_lock: true #允许锁定内存
network.host: 0.0.0.0
http.max_content_length: 200mb
network.tcp.keep_alive: true
network.tcp.no_delay: true
http.port: 9200
http.cors.enabled: true #允许http跨域访问，es_head插件必须开启
http.cors.allow-origin: "*" #允许http跨域访问，es_head插件必须开启
discovery.seed_hosts: ["ypd-dmcp-log01", "ypd-dmcp-log02"]
cluster.initial_master_nodes: ["ypd-dmcp-log01", "ypd-dmcp-log02"]
xpack.monitoring.collection.enabled: true #添加这个配置以后在kibana中才会显示联机状态，否则会显示脱机状态
xpack.security.enabled: true
#xpack.security.enrollment.enabled: true
xpack.security.http.ssl.enabled: true
xpack.security.http.ssl.keystore.path: elastic-certificates.p12 #我把文件都放在config下。所以直接写文件名，放在别处需要写路径
xpack.security.http.ssl.truststore.path: elastic-certificates.p12
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: elastic-certificates.p12k
xpack.security.transport.ssl.truststore.path: elastic-certificates.p12
配置jvm内存大小
修改 jvm.options
-Xms6g #你服务器内存的一半，最高32G
-Xmx6g #你服务器内存的一半，最高32G改好文件夹准备生成相关key
创建ca证书，什么也不用输入，两次回车即可（会在当前目录生成名为elastic-stack-ca.p12的证书文件）
bin/elasticsearch-certutil ca使用之前生成的ca证书创建节点证书，过程三次回车，会在当前目录生成一个名为elastic-certificates.p12的文件
bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12生成http证书，根据提示信息进行操作，主要是下面几步
bin/elasticsearch-certutil http
Generate a CSR? [y/N]n
Use an existing CA? [y/N]y
CA Path: /usr/local/elasticsearch-8.10.4/config/certs/elastic-stack-ca.p12
Password for elastic-stack-ca.p12: 直接回车，不使用密码
For how long should your certificate be valid? [5y] 50y#过期时间
Generate a certificate per node? [y/N]n
Enter all the hostnames that you need, one per line. #输入es的节点 两次回车确认
When you are done, press <ENTER> once more to move on to the next step.
es1
es2
es3
You entered the following hostnames.
- es1
- es2
- es3
Is this correct [Y/n]y
When you are done, press <ENTER> once more to move on to the next step. #输入es的ip 两次回车确认
192.168.1.1
192.168.1.2
192.168.1.3
You entered the following IP addresses.
- 192.168.1.1
- 192.168.1.2
- 192.168.1.3
Is this correct [Y/n]y
Do you wish to change any of these options? [y/N]n
接下来一直回车，然后会在当前目录生成名为：elasticsearch-ssl-http.zip的压缩文件
解压缩http证书文件到config下，证书在http文件夹里。名字是http.p12，mv出来到config下
确保elasticsearch目录下所有文件的归属关系都是es用户
chown -R es:es /home/es/elasticsearch-8.10.4启动es
su - es #到es用户下
bin/elasticsearch 初次可以前台启动 没问题就放后台
bin/elasticsearch -d复制整个es文件夹到es2，es3
只需要修改
node.name: es2 #节点名称
network.host: 192.168.1.2 #节点ip
node.name: es3 #节点名称
network.host: 192.168.1.3 #节点ip浏览器访问一下es的web ui
https://192.168.1.1:9200
生成账户密码
bin/elasticsearch-setup-passwords interactive
warning: ignoring JAVA_HOME=/usr/local/java/jdk1.8.0_361; using bundled JDK
******************************************************************************
Note: The 'elasticsearch-setup-passwords' tool has been deprecated. This command will be removed in a future release.
******************************************************************************
Initiating the setup of passwords for reserved users elastic,apm_system,kibana,kibana_system,logstash_system,beats_system,remote_monitoring_user.
You will be prompted to enter passwords as the process progresses.
Please confirm that you would like to continue [y/N]y
Enter password for [elastic]:
Reenter password for [elastic]:
Enter password for [apm_system]:
Reenter password for [apm_system]:

Changed password for user [apm_system]
Changed password for user [kibana_system]
Changed password for user [kibana]
Changed password for user [logstash_system]
Changed password for user [beats_system]
Changed password for user [remote_monitoring_user]
Changed password for user [elastic]
这个时候就可以使用账号密码访问了创建一个给kibana使用的用户
bin/elasticsearch-users useradd kibanauser
kibana不能用es超级用户，此处展示一下用法
bin/elasticsearch-users roles -a superuser kibanauser
加两个角色 不然没有监控权限
bin/elasticsearch-users roles -a kibana_admin kibanauser
bin/elasticsearch-users roles -a monitoring_user kibanauser
然后配置kibana
解压然后修改kibana.yml
server.port: 5601
server.host: "0.0.0.0"
server.ssl.enabled: true
server.ssl.certificate: /data/elasticsearch-8.10.4/config/client.cer
server.ssl.key: /data/elasticsearch-8.10.4/config/client.key
elasticsearch.hosts: ["https://192.168.1.1:9200"]
elasticsearch.username: "kibanauser"
elasticsearch.password: "kibanauser"
elasticsearch.ssl.certificate: /data/elasticsearch-8.10.4/config/client.cer
elasticsearch.ssl.key: /data/elasticsearch-8.10.4/config/client.key
elasticsearch.ssl.certificateAuthorities: [ "/data/elasticsearch-8.10.4/config/client-ca.cer" ]
elasticsearch.ssl.verificationMode: certificate
i18n.locale: "zh-CN"
xpack.encryptedSavedObjects.encryptionKey: encryptedSavedObjects1234567890987654321
xpack.security.encryptionKey: encryptionKeysecurity1234567890987654321
xpack.reporting.encryptionKey: encryptionKeyreporting1234567890987654321
启动
bin/kibana访问 https://ip:5601
配置logstash
解压后在conf下创建一个配置文件，我取名logstash.conf
input {
kafka {
bootstrap_servers => "192.168.1.1:9092"
group_id => "logstash_test"
client_id => 1 #设置相同topic,设置相同groupid,设置不同clientid,实现LogStash多实例并行消费kafka
topics => ["testlog"]
consumer_threads => 2 #等于 topic分区数
codec => json { #添加json插件，filebeat发过来的是json格式的数据
charset => "UTF-8"
}
decorate_events => false #此属性会将当前topic、offset、group、partition等信息也带到message中
type => "testlog" #跟topics不重合。因为output读取不了topics这个变量
}
}
filter {
mutate {
remove_field => "@version" #去掉一些没用的参数
remove_field => "event"
remove_field => "fields"
}
}
output {
elasticsearch {
cacert => "/data/elasticsearch-8.10.4/config/client-ca.cer"
ssl => true
ssl_certificate_verification => false
user => elastic
password => "123456"
action => "index"
hosts => "https://192.168.1.1:9200"
index => "%{type}-%{+YYYY.MM.dd}"
}
}
修改jvm.options
-Xms6g #你服务器内存的一半，最高32G
-Xmx6g #你服务器内存的一半，最高32G
启动logstash
bin/logstash -f conf/logstash.conf最后去服务器上部署filebeat 文章来源：https://www.toymoban.com/news/detail-764435.html
filebeat.inputs:
- type: filestream 跟以前的log类似。普通的日志选这个就行了
id: testlog1
enabled: true
paths:
- /var/log/testlog1.log
field_under_root: true #让kafka的topic: '%{[fields.log_topic]}'取到变量值
fields:
log_topic: testlog1 #跟id不冲突，id输出取不到变量值
multiline.pattern: '^\d(4)' # 设置多行合并匹配的规则，意思就是不以4个连续数字，比如2023开头的 视为同一条
multiline.negate: true # 如果匹配不上
multiline.match: after # 合并到后面
- type: filestream
id: testlog2
enabled: true
paths:
- /var/log/testlog2
field_under_root: true
fields:
log_topic: testlog2
multiline.pattern: '^\d(4)'
multiline.negate: true
multiline.match: after
filebeat.config.modules:
path: ${path.config}/modules.d/*.yml
reload.enabled: true #开启运行时重载配置
#reload.period: 10s
path.home: /data/filebeat-8.10.4/ #指明filebeat的文件夹。启动多个时需要
path.data: /data/filebeat-8.10.4/data/
path.logs: /data/filebeat-8.10.4/logs/
processors:
- drop_fields: #删除不需要显示的字段
fields: ["agent","event","input","log","type","ecs"]
output.kafka:
enabled: true
hosts: ["10.8.74.35:9092"] #kafka地址，可配置多个用逗号隔开
topic: '%{[fields.log_topic]}' #根据上面添加字段发送不同topic
初步的部署这就完成了。后面的使用才是大头，路漫漫其修远兮 文章来源地址https://www.toymoban.com/news/detail-764435.html
