Logstash 是一个功能强大的工具，可与各种部署集成。 它提供了大量插件，可帮助你解析，丰富，转换和缓冲来自各种来源的数据。 如果你的数据需要 Beats 中没有的其他处理，则需要将 Logstash 添加到部署中。配套有各种轻量级beats收集工具，比如Heartbeat能够通过ICMP、TCP和HTTP进行ping检测主机可用性。在第三方组件里面，Fluented最近比较火。Filebeat比较轻量，适合收集容器环境日志，具有各种插件。
本节教程主机集群环境配置信息：
host hostname
192.168.31.101 es1
192.168.31.102 es2
192.168.31.103 es3
192.168.31.104 web1
检查ubuntu虚拟机操作系统版本信息：
root@web1:/usr/local/src# uname -r
5.15.0-57-generic
修改ubuntu虚拟机名称为web1
root@web1:~# vim /etc/hostname
web1.example.com
root@web1:reboot
root@web1:~# cd /usr/local/src
logstash软件包需要从官网或者清华大学镜像站等权威网站下载，需要注意的是logstash自带jdk，我从虚拟机利用xftp工具上传并安装logstash安装包:
由于logstash需要使用普通用户身份启动，可能出现部分日志无法读取的情况，是因为日志缺少普通用户读取权限，logstash必须具备对系统全部日志的读取权限。
root@web1:~# dpkg -i logstash-8.5.1-amd64.deb #dpkg方式安装logstash组件
Selecting previously unselected package logstash.
(Reading database ... 202869 files and directories currently installed.)
Preparing to unpack logstash-8.5.1-amd64.deb ...
Unpacking logstash (1:8.5.1-1) ...
Setting up logstash (1:8.5.1-1) ...
查看logstash默认配置文件信息，可以发现User和Group默认都是logstash
root@web1:~# cat /lib/systemd/system/logstash.service|grep -E 'User|Group' #查找配置文件默认用户和用户组信息
User=logstash
Group=logstash
由于Linux系统部分系统日志缺少“其他用户”权限，比如yum.log日志没有logstash用户权限，为了演示需要，将logstash组件启动默认用户和默认用户组改为root用户：
[root@web1 log]# ls -al /var/log/yum.log #yum.log文件没有logstash用户权限
-rw------- 1 root root 0 Jan 1 13:34 /var/log/yum.log

配置文件修改完毕，首先做个测试，查看logstash服务功能运行是否正常：
root@web1:/etc/logstash/conf.d# vim stdin-stout-test.conf #编辑配置文件
input {
stdin {
id => "my_plugin_id"
}
}
output {
stdout {
}
}
root@web1:/etc/logstash/conf.d# /usr/share/logstash/bin/logstash -f stdin-stout-test.conf -t #使用配置文件测试logstash

通过应用elasticsearch-head插件，检查es1节点（192.168.31.101）生成的索引数据：
需要注意，为了避免不必要的报错 ，elasticsearch、logstash、kibana三个组件版本务必保持一致，此处都是8.5.1版本。为了检验效果，需要做个测试，新建配置文件syslog-to-es.conf，内容如下所示：
root@web1:/etc/logstash/conf.d# vim syslog-to-es.conf
input{
file{
path => "/var/log/syslog"
type => "systemlog" #日志类型
start_position => "beginning" #开始位置
stat_interval => "10" #采样间隔，此处每10秒采集一次
}
}
output{
if[type]=="systemlog"{ #首先判断是否systemlog类型
elasticsearch{
hosts =>["192.168.31.101:9200"] #es1服务器地址
index =>"manager-systemlog-%{+YYYY.MM.dd}" #索引文件名称
password =>"123456
user => "manager"
}}
}
root@web1:/etc/logstash/conf.d# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/syslog-to-es.conf -t
root@web1:/etc/logstash/conf.d# systemctl start logstash && systemctl enable logstash
Created symlink /etc/systemd/system/multi-user.target.wants/logstash.service → /lib/systemd/system/logstash.service.
可以发现logstash服务启动以后，已经生成索引文件
登录elasticsearch-head应用插件，验证测试数据：
索引数据写好以后，需要安装kibana进行数据展示，在es1服务器上安装kibana组件：
root@es1:/usr/local/src# dpkg -i kibana-8.5.1-amd64.deb #安装kibana
Selecting previously unselected package kibana.
(Reading database ... 202869 files and directories currently installed.)
Preparing to unpack kibana-8.5.1-amd64.deb ...
Unpacking kibana (8.5.1) ...
Setting up kibana (8.5.1) ...
Creating kibana group... OK
Creating kibana user... OK
Created Kibana keystore in /etc/kibana/kibana.keystore
kibana安装完毕，修改配置文件kibana.yml，内容如下所示：
root@es1:~# vim /etc/kibana/kibana.yml
server.port: 5601 #服务端口
server.host:"0.0.0.0" #监听端口
elasticsearch.hosts: ["http://192.168.31.103:9200"] #连接es3主机（也可以是es1、es2）
elasticsearch.username: "kibana_system" #用户名
elasticsearch.password: "123456" #密码
i18n.locale: "zh-CN" #中文显示
通过配置文件，启动kibana服务
root@es1:~# systemctl restart kibana.service
root@es1:~# systemctl enable kibana.service
Created symlink /etc/systemd/system/multi-user.target.wants/kibana.service → /lib/systemd/system/kibana.service.
通过检查进程、端口、日志等，充分检查kibana服务是否启动成功：
root@es1:/usr/local/src# ps aux|grep kibana

(省略部分输出，确保没有报错信息)
在360浏览器地址输入“192.168.31.101:5601”，首次访问启动界面如下所示：
输入用户名manager，密码123456，首次登录Elasticsearch
点击Management-stackmanager，创建数据视图：
创建数据视图，通过前期配置，Kibana能够自动访问es3节点内部索引数据
点击“创建数据视图”，如下所示：
按照命名习惯，数据视图名称填写“manager-systemlog”，索引模式即正则，填写“manager-systemlog-*”，代表找到所有以manager-systemlog开头的索引文件，时间戳字段选择默认“@timestamp”，系统自动匹配到2个源：manager-systemlog-2023.01.27、manager-systemlog-2023.01.28
点击“保存数据视图到Kibanad”，生成名称为manager-systemlog的数据视图：
选择Analytics下面的Discover，可以看到数据视图manager-systemlog
点击manager-systemlog，查看如下索引数据：
此处可以做个实验，在web1服务器上插入索引数据
root@web1:~# echo "111111" >> /var/log/syslog
root@web1:~# echo "222222" >> /var/log/syslog
切换kibana，可以看到上述两条索引数据已经在日志中生成，
演示收集多个不同类型日志，首先重新创建配置文件sys-to-es.conf
root@web1:/etc/logstash/conf.d# vim syslog-to-es.conf
input{
file{
path => "/var/log/syslog"
type => "systemlog"
start_position => "beginning"
stat_interval => "10"
}
file{
path => "/var/log/auth.log"
type => "authlog"
start_position => "beginning"
stat_interval => "10"
}
}
output{
if[type]=="systemlog"{
elasticsearch{
hosts =>["192.168.31.101:9200"]
index =>"manager-systemlog-%{+YYYY.MM.dd}"
password =>"123456"
user => "manager"
}}
if[type]=="authlog"{
elasticsearch{
hosts =>["192.168.31.101:9200"]
index =>"manager-authlog-%{+YYYY.MM.dd}"
password =>"123456"
user =>"manager"
}}
检查配置文件，重启logstash服务
root@web1:/etc/logstash/conf.d# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/syslog-to-es.conf -t #检查是否能够正常启动

同理，在kibana中创建manager-authlog视图：
通过elasticsearch-head应用插件进行查看，发现已经生成manager-systemlog-*和manager-authlog-*日志
