filebeat 6.4.3 采集 nginx日志

nginx 日志格式规范：

将日志配置组合添加至nginx主配置文件；

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

ES集群安装插件

集群收集nginx日志需要安装 ingest-user-agent ，ingest-geoip ，安装完成之后需要重启es 服务，否则数据无法正常录入es集群。

/usr/share/elasticsearch/bin/elasticsearch-plugin install ingest-user-agent
/usr/share/elasticsearch/bin/elasticsearch-plugin install ingest-geoip
/usr/share/elasticsearch/bin/elasticsearch-plugin list

升级java至1.8

yum install java-1.8 -y

安装filebeat

导入key

rpm --import ​​https://artifacts.elastic.co/GPG-KEY-elasticsearch​​

创建repo 文件

more lostash.repo

[elastic-6.x]
name=Elastic repository for 6.x packages
baseurl=​​​https://artifacts.elastic.co/packages/6.x/yum​​​gpgcheck=1
gpgkey=​​​https://artifacts.elastic.co/GPG-KEY-elasticsearch​​​enabled=1
autorefresh=1
type=rpm-md

安装

yum install filebeat -y

修改filebeat主配置文件

more /etc/filebeat/filebeat.yml

filebeat.config:
prospectors:
path: ${path.config}/prospectors.d/.yml
reload.enabled: false
modules:
path: /etc/filebeat/modules.d/.yml
reload.enabled: false

output.elasticsearch:
hosts: ['10.2.3.30:9200']

setup.kibana:
host: "10.2.3.13:5601"

配置filebeat nginx 模块

Access 日志：/data/nginxlog/eslog/es-access.*
Error 日志：/data/nginxlog/eslog/es-error.*
more /etc/filebeat/modules.d/nginx.yml 
- module: nginx
  # Access logs
  access:
    enabled: true

    # Set custom paths for the log files. If left empty,
    # Filebeat will choose the paths depending on your OS.
    var.paths: ["/data/nginxlog/eslog/es-access.*"]
  # Error logs
  error:
    enabled: true

    # Set custom paths for the log files. If left empty,
    # Filebeat will choose the paths depending on your OS.
    var.paths: ["/data/nginxlog/eslog/es-error.*"]

添加启动

systemctl enable filebeat

开启nginx 模块

cd /etc/filebeat

filebeat modules enable nginx

filebeat modules list

初始化环境

此操作会自动导入filebeat模板和nginx dashboard 到es 集群：

Set up the initial environment:
Loaded index template
Loading dashboards (Kibana must be running and reachable)
Loaded dashboards
Loaded machine learning job configurations
./filebeat setup -e

启动服务

systemctl start filebeat

启动服务报错

内容如下：

Exiting: Error importing Kibana dashboards: fail to import the dashboards in Kibana: Error importing directory /usr/share/filebeat/kibana: Failed to import index-pattern: Failed to load directory /usr/share/filebeat/kibana/6/index-pattern:

处理办法：

登陆kibana 进入Dev tools 删除

删除旧模板
#DELETE _template/filebeat-6.X.X
删除旧数据
#DELETE filebeat-6.4.2-*
重新导入模板：

cd /etc/filebeat/
filebeat setup
Loaded index template
Loading dashboards (Kibana must be running and reachable)
Loaded dashboards
Loaded machine learning job configurations

重启服务：

systemctl restart filebeat
