Logstash是一个接收，处理，转发日志的工具。支持系统日志，webserver日志，错误日志，应用日志，总之包括所有可以抛出来的日志类型。
典型的使用场景下(ELK)：
用Elasticsearch作为后台数据的存储，kibana用来前端的报表展示。Logstash在其过程中担任搬运工的角色，它为数据存储，报表查询和日志解析创建了一个功能强大的管道链。Logstash提供了多种多样的 input,filters,codecs和output组件，让使用者轻松实现强大的功能。
学习Logstash最好的资料就是官网，介绍三个学习地址：
1、ELK官网帮助文档

2、Logstash匹配帮助文档

3、Grok在线正则匹配

下面就正式开始主题~~
logstash部署配置
1、基础环境支持（JAVA）
yum -y install java-1.8*java --version
2、下载解压logstash
logstash-5.0.1.tar.gz tar -zxvf logstash-5.0.1.tar.gz cd logstash-5.0.1 mkdir conf #创建conf文件夹存放配置文件 cd conf
3、配置文件
配置test文件（结合前面搭建好的ES集群测试）
[[email protected] conf]# cat test.conf
input {
stdin {
}
}
output {
elasticsearch {
hosts =>["172.16.81.133:9200","172.16.81.134:9200"]
index => "test-%{+YYYY.MM.dd}"
}
stdout {
codec => rubydebug
}
}
#检查配置文件语法
[[email protected] conf]# /opt/logstash-5.0.1/bin/logstash -f /opt/logstash-5.0.1/conf/test.conf --config.test_and_exit
Sending Logstash‘s logs to /opt/logstash-5.0.1/logs which is now configured via log4j2.properties
Configuration OK
[2017-12-26T11:42:12,816][INFO ][logstash.runner ] Using config.test_and_exit mode. Config Validati on Result: OK. Exiting Logstash
#执行命令
/opt/logstash-5.0.1/bin/logstash -f /opt/logstash-5.0.1/conf/test.conf
手动输入信息
2017.12.26 admin 172.16.81.82 200
结果：
{
"@timestamp" => 2017-12-26T03:45:48.926Z,
"@version" => "1",
"host" => "0.0.0.0",
"message" => "2017.12.26 admin 172.16.81.82 200",
"tags" => []
}
配置kafka集群的logstash配置文件
客户端logstash推送日志
#配置客户端logstash配置文件
[[email protected] conf]# cat nginx_kafka.conf
input {
file {
type => "access.log"
path => "/var/log/nginx/imlogin.log"
start_position => "beginning"
}
}
output {
kafka {
bootstrap_servers => "172.16.81.131:9092,172.16.81.132:9092"
topic_id => ‘summer‘
}
}
配置服务端logstash过滤分割日志
[[email protected] conf]# cat kafka.conf
input {
kafka {
bootstrap_servers => "172.16.81.131:9092,172.16.81.132:9092"
group_id => "logstash"
topics => ["summer"]
consumer_threads => 50
decorate_events => true
}
}
filter {
grok {
match => {
"message" => "%{NOTSPACE:accessip} \- \- \[%{HTTPDATE:time}\] %{NOTSPACE:auth} %{NOTSPACE:uri_stem} %{NOTSPACE:agent} %{WORD:status} %{NUMBER:bytes} %{NOTSPACE:request_url} %{NOTSPACE:browser} %{NOTSPACE:system} %{NOTSPACE:system_type} %{NOTSPACE:tag} %{NOTSPACE:system}"
}
}
date {
match => [ "logdate", "MMM dd YYYY HH:mm:ss" ]
}
}
output {
elasticsearch {
hosts => ["172.16.81.133:9200","172.16.81.134:9200"]
index => "logstash-%{+YYYY.MM.dd}"
}
}
然后再es集群上观察消费情况
[[email protected] ~]# curl -XGET ‘172.16.81.134:9200/_cat/indices?v&pretty‘
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size

green open logstash-2017.12.29.05 kPQAlVkGQL-izw8tt2FRaQ 5 1 1289 0 2mb 1mb
配合ES集群的head插件使用！！观察日志生成情况！！
4、kibana安装部署
下载rpm包
kibana-5.0.1-x86_64.rpm
安装kibana软件
rpm -ivh kibana-5.0.1-x86_64.rpm
配置文件
[[email protected] opt]# cat /etc/kibana/kibana.yml | grep -v "^#" | grep -v "^$"
server.port: 5601
server.host: "172.16.81.133"
elasticsearch.url: "http://172.16.81.133:9200"
启动kibana
systemctl start kibana systemctl enable kibana
浏览器浏览
http://172.16.81.133:5601/
正常显示数据！！
有问题请指出！出现了很多IP地址不知道可以查看前面几篇！
