logstash收集nginx日志、filebeat
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
