环境说明
架构说明及架构图
filebeat部署在客户端用于收集日志并把收集到的日志发送到logstash.
logstash把收集到的日志处理之后交给elasticsearch.
kibana从elasticsearch中提取数据并进行展示.
之所以使用filebeat进行日志收集是因为filebeat不会像logstash使用大量的资源,影响业务服务器.
环境需求
需要Java环境和redis
yum install java
yum install redis使用版本
java 1.8.0_111
redis 2.8.16
filebeat 5.1.2
logstash 5.1.2
elasticsearch 5.1.1
kibana 5.1.1
安装配置
filebeat安装及配置
安装filebeat
rpm --import
cat > /etc/yum.repos.d/elk.repo <<EOF
[elasticsearch-5.x]
name=Elasticsearch repository for 5.x packages
baseurl=https://artifacts.elastic.co/packages/5.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md
EOF
yum clean all
yum install filebeat -y
配置filebeat
vim /etc/filebeat/filebeat.yml
paths:
- /var/log/nginx/access.log
tags: ["nginx"]
output.logstash:
hosts: ["1.8.101.53:5044"]
其中path选项为filebeat发送给logstash的路径, 多个日志可以使用*.log通配. file不会自动递归日志目录下的子目录, 如果需要递归子目录可以使用类似 /var/log/*/*.log 的结构. tags选项会向log中添加一个标签, 此标签可以提供给logstash用于区分不同客户端不同业务的log. output指定发送log到哪台服务器的哪个服务, 默认输出到elasticsearch. 本例使用logstash, 所以需要注释掉发送到elasticsearch的配置, 并启用发送到logstash的配置.
