#ELK 6安装配置 nginx日志收集 kabana汉化

#环境 centos 7.4 ,ELK 6 ,单节点

#服务端
Logstash 收集,过滤
Elasticsearch 存储,索引日志
Kibana 可视化
#客户端
filebeat 监控、转发,作为agent

filebeat-->Logstash-->Elasticsearch-->Kibana

#基本配置

#时间同步
#关闭selinux
#内核优化
#防火墙端口

#浏览器访问kabana设置

首次打开,需要添加索引模式
#Management管理-->Index Patterns索引模式-->Create index pattern创建索引模式
填写*(索引名)-->Next step-->选择如@timestamp-->Create index pattern ,完成
#Index pattern 下面填写logstash配置的名称如type => "logs"填写logs

#filebeat配置 (轻量客户端)

yum install -y filebeat 

#查看配置

rpm -qc filebeat
egrep -v ‘#|^$‘ /etc/filebeat/filebeat.yml
cp /etc/filebeat/filebeat.yml{,.bak}

#收集nginx日志试列

 #安装nginx
rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
yum install -y nginx
systemctl start nginx
curl localhost
 #查看nginx日志
tail /var/log/nginx/access.log

#配置filebeat收集nginx日志

echo ‘#filebeat#
filebeat.prospectors:
#nginx
- input_type: log
  enable: yes
  #tags: nginx-access
  paths:
    - /var/log/nginx/access.log
  exclude_lines: ["^$"]
  fields:
    type: "nginx-access"
  fields_under_root: true

output.logstash:
  hosts: ["localhost:5044"]
  #hosts: ["172.16.50.32:5044"]
  #index: filebeat
‘>/etc/filebeat/filebeat.yml

#启动

 systemctl enable  filebeat  
 systemctl restart filebeat  
 systemctl status  filebeat  

#在kibana查看日志


#logstash使用grok过滤nginx日志

nginx日志有main和log_json两种,默认为main普通文本格式
ELK存储为json格式,文本格式华,拆分出如ip地址、访问agent等,便于后续使用

#nginx默认日志格式

    log_format  main  ‘$remote_addr - $remote_user [$time_local] "$request" ‘
                      ‘$status $body_bytes_sent "$http_referer" ‘
                      ‘"$http_user_agent" "$http_x_forwarded_for"‘;

 #curl localhost生成日志格式如下
 #127.0.0.1 - - [22/Mar/2018:18:37:37 +0800] "GET / HTTP/1.1" 200 612 "-" "curl/7.29.0" "-"

#logstash配置,使用grok过滤nginx日志

grok使用的正则表达式在grok-patterns文件
可以引用或添加自定义规则
Grok=$(find / -name grok-patterns)
echo $Grok
#/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-patterns-core-4.1.2/patterns/grok-patterns

 #创建nginx正则表达式(引用grok正则)  
echo ‘#nginx-access
WZ ([^ ]*)
NGINXACCESS %{IP:remote_ip} \- \- \[%{HTTPDATE:timestamp}\] "%{WORD:method} %{WZ:request} HTTP/%{NUMBER:httpversion}" %{NUMBER:status} %{NUMBER:bytes} %{QS:referer} %{QS:agent} %{QS:xforward}
‘>/etc/logstash/conf.d/nginx-access


 #重新生成logstash配置文件  
echo ‘
input {

 #收集本地log#
  file {
     type => "logtest"
     path => "/var/log/logtest.txt"
     start_position => "beginning"
  }

 #filebeat客户端#
  beats {
     port => 5044
  }

}

 # #筛选
filter {

# 如果是nginx访问日志
  if ( [type] == "nginx-access" ) {

    #按字段切割
    grok { 
      patterns_dir=>"/etc/logstash/conf.d/nginx-access"
      match => { "message" => "%{NGINXACCESS}" }
      }

    # 时间格式转换
    date {
      match => [ "timestamp", "dd/MMM/YYYY:HH:mm:ss Z" ]
      }

    # 删除不需要的字段
    mutate { 
      remove_field => [ "offset", "@version", "beat", "input_type", "tags","id"]
      }
    }
}

output {

#标准输出,调试使用#
  stdout {
   codec => rubydebug { }
  }

# 输出到es#
  elasticsearch {
    hosts => ["http://172.16.50.32:9200"]
    index => "%{type}-%{+YYYY.MM.dd}"
  }

}
‘>/etc/logstash/conf.d/logstash-01.conf

#检测配置

/usr/share/logstash/bin/logstash -t -f /etc/logstash/conf.d/logstash-01.conf 

#调试logstash

 #关闭
systemctl stop  logstash
 #在终端启动查看
/usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/logstash-01.conf

#访问nginx产生日志,在elasticsearch-head或者kabana查看nginx日志

logstash配置文件可拆分为多个,按input、filter、output类型+序列号指定优先级


#elasticsearch调试工具(可选)

# elasticsearch安装head插件

 #安装NodeJS (epel源)  
yum install -y nodejs
 #安装npm  
npm install -g cnpm --registry=https://registry.npm.taobao.org
 #使用npm安装grunt  
npm install -g grunt

 #安装elasticsearch-head
 #查看https://github.com/mobz/elasticsearch-head
mkdir /opt/head
cd /opt/head
git clone git://github.com/mobz/elasticsearch-head.git
cd elasticsearch-head
npm install
 #启动
npm run start &

 #配置elasticsearch访问
echo ‘#elasticsearch-head
http.cors.enabled: true
http.cors.allow-origin: "*"
‘>>/etc/elasticsearch/elasticsearch.yml

 #重启elasticsearch
systemctl restart elasticsearch

 #浏览器访问9100端口 
http://ip:9100/
 #出现“未连接”,请修改localhost为ip地址
