logstash收集nginx日志

使用Beats采集日志(filebeat)

logstash收集nginx日志

1.

133上(在logstash这台机器上加入这个配置文件)

编辑配置文件 vi /etc/logstash/conf.d/nginx.conf//加入如下内容

input {
  file {
    path => "/tmp/elk_access.log"
    start_position => "beginning"
    type => "nginx"
  }
}
filter {
    grok {
        match => { "message" => "%{IPORHOST:http_host} %{IPORHOST:clientip} - %{USERNAME:remote_user} \[%{HTTPDATE:timestamp}\] \"(?:%{WORD:http_verb} %{NOTSPACE:http_request}(?: HTTP/%{NUMBER:http_version})?|%{DATA:raw_http_request})\" %{NUMBER:response} (?:%{NUMBER:bytes_read}|-) %{QS:referrer} %{QS:agent} %{QS:xforwardedfor} %{NUMBER:request_time:float}"}
    }
    geoip {
        source => "clientip"
    }
}
output {
    stdout { codec => rubydebug }
    elasticsearch {
        hosts => ["192.168.193.133:9200"]
	index => "nginx-test-%{+YYYY.MM.dd}"
  }

  }

input { #输入

file { #此处指定一个文件,把这个文件的内容,作为logstash的输入

path => "/tmp/elk_access.log" #指定这个文件的路径

start_position => "beginning" #指定这个文件从什么时候开始收集

type => "nginx" #自定义

}

}

filter { #这个是对这个日志对一个过滤(比如输出格式)。所以访问日志的格式也要定义,下面会编辑nginx日志的格式(第3步骤)

grok {

match => { "message" => "%{IPORHOST:http_host} %{IPORHOST:clientip} - %{USERNAME:remote_user} \[%{HTTPDATE:timestamp}\] \"(?:%{WORD:http_verb} %{NOTSPACE:http_request}(?: HTTP/%{NUMBER:http_version})?|%{DATA:raw_http_request})\" %{NUMBER:response} (?:%{NUMBER:bytes_read}|-) %{QS:referrer} %{QS:agent} %{QS:xforwardedfor} %{NUMBER:request_time:float}"}

}

geoip {

source => "clientip"

}

}

output { #输出

stdout { codec => rubydebug }

elasticsearch {

hosts => ["192.168.193.133:9200"]

index => "nginx-test-%{+YYYY.MM.dd}"

}                                                                                                                                                                                                                                          

}

#(注意花括号)配置不对会找不到nginx-test

2.

下面是配置代理。我们要产生日志,得去配置。配置之前要先检测一下,上面写的日志是否正确:

以下在132上操作

检测配置文件是否有错

cd /usr/share/logstash/bin

./logstash --path.settings /etc/logstash/ -f /etc/logstash/conf.d/nginx.conf --config.test_and_exit

yum install -y nginx #没有nginx要安装

vi /etc/nginx/conf.d/elk.conf//写入如下内容 #写一个虚拟主机配置文件

server {


listen 80;

server_name elk.aming.com;




location / {

proxy_pass http://192.168.193.128:5601; #代理的目标

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

access_log /tmp/elk_access.log main2; #自动生成

}

3.

以下在132上操作

vim /etc/nginx/nginx.conf//增加如下内容 #定义nginx的日志格式

log_format main2 '$http_host $remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$upstream_addr" $request_time';

nginx -t #解释

/usr/local/nginx/sbin/nginx -t

 /usr/local/nginx/sbin/nginx -s reload

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

systemctl start nginx

绑定hosts 192.168.193.132 elk.aming.com

浏览器访问,检查是否有日志产生

systemctl restart logstash

4.

128上curl  '192.168.193.128:9200/_cat/indices?v'

health status index                 uuid                   pri rep docs.count docs.deleted store.size pri.store.size
yellow open   .kibana               HUhL8JS6Sgqxr8mSq9UgoQ   1   1          2            0      7.2kb          7.2kb
yellow open   system-syslog-2019.06 fqLpMdxRTG2EAV5DC8eIMw   5   1        840            0    526.9kb        526.9kb

查看有没有日志

ls /tmp/elk_access.log

/tmp/elk_access.log

wc -l !$

wc -l /tmp/elk_access.log
0 /tmp/elk_access.log

cat !$

检查是否有nginx-test开头的索引生成

如果有,才能到kibana里去配置该索引

左侧点击“Managerment”-> “Index Patterns”-> “Create Index Pattern”

Index pattern这里写nginx-test-* #支持统配,直接这样写就可以

之后点击左侧的Discover

使用Beats采集日志(filebeat)

beats属于一个轻量的日志采集器。而logstash在启动的时候很慢,会消耗资源。那我们可以尝试着使用beats去采集日志。

beats可以自定义我们想要的beats

https://www.elastic.co/cn/products/beats

filebeat metricbeat packetbeat winlogbeat auditbeat heartbeat #filebeat的成员组件(我们用到的是filebeat,他是针对日志的)

可扩展,支持自定义构建

在133上执行

wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-6.0.0-x86_64.rpm

rpm -ivh filebeat-6.0.0-x86_64.rpm #下载rpm包安装filebeat

以下是在屏幕上的输出:

首先编辑配置文件

vim /etc/filebeat/filebeat.yml //增加或者更改 #注意文件的格式,空格

filebeat.prospectors:

- input_type: log #定义input类型是log(此处type前面的input字样,在新版本不会出现,需注意)

paths: #定义日志的路径

- /var/log/messages

output.console: #此处文件里可能没有output.console:,需要添加这两行进去。但是添加完,要将out.elasticsearch:注释掉。如下图:

enable: true

/usr/share/filebeat/bin/filebeat -c /etc/filebeat/filebeat.yml //可以在屏幕上看到对应的日志信息 #-c指定配置文件,启动filebeat

以下是以服务的角色出现:

再编辑配置文件

vim /etc/filebeat/filebeat.yml //增加或者更改

filebeat.prospectors:

- input_type: log

paths:

- /var/log/messages #针对这个日志

output.elasticsearch: #注意此处跟上面有区分,就不是output.console:了

hosts: ["192.168.133.130:9200"] #如下图:

systemctl start filebeat

ps aux |grep filebeat

然后,可以在kibana上创建新的索引
