Elastic+logstash+filebeat做Nginx日志分析

一、Elasticserach安装
1、Installation(elastic 6.3.2 版本 依赖 java JDK8)

下载合适的版本：
curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.4.0.tar.gz
tar -xvf elasticsearch-6.4.0.tar.gz
cd elasticsearch-6.4.0/bin
./elasticsearch

2、集群健康检查
curl -XGET http://127.0.0.1:9200/_cat/health?v 集群健康查看
curl -XGET http://127.0.0.1:9200/_cat/nodes?v 节点状态查看
curl -XGET http://127.0.0.1:9200/_cat/indices?v 查看索引
curl -XPUT http://127.0.0.1:9200/customer?pretty 添加customer索引
curl -XDELETE http://127.0.0.1:9200/customer?pretty 删除索引

3、Config
cluster.name: 集群名
node.name: 节点名
path.data: 数据存储路径
path.logs: 日志存储路径
network.host: 监听地址
http.port: 监听端口
JVM 配置、logging配置 参考官方文档
重要参数：

Path settings
Cluster name
Node name
Network host
Discovery settings
Heap size
Heap dump path
GC logging
Temp directory
重要的系统参数：

Disable swapping
Increase file descriptors
Ensure sufficient virtual memory
Ensure sufficient threads
JVM DNS cache settings

4、Running as daemon
./bin/elasticsearch -d -p pid 启动
kill cat pid 停止

5、Set up X-Pack
参考x-pack破解方法

二、kibana安装及配置

        wget https://artifacts.elastic.co/downloads/kibana/kibana-6.4.0-linux-x86_64.tar.gz

tar -xzf kibana-6.4.0-linux-x86_64.tar.gz
cd kibana-6.4.0-linux-x86_64/

        1、启动  ./bin/kibana   

        2、config：

server.port: 5601
server.host: "192.168.12.81"
kibana.index: ".kibana"
elasticsearch.username: "elastic"
elasticsearch.password: "dinpay"

三、logstash安装及配置
wget https://artifacts.elastic.co/downloads/logstash/logstash-6.4.0.tar.gz

配置 filebeat 收集Nginx日志： （Nginx.conf）

input {
beats {
port => 5044
codec => "json"
}
}

output {
elasticsearch {
hosts => ["127.0.0.1:9200"]
index => "test1-nginx-access-%{+YYYY.MM.dd}"
template_overwrite => true
user => elastic
password => dinpay
}
}

配置logstash.yml elastic安装在本机（没有配置https）

xpack.monitoring.enabled: true
xpack.monitoring.elasticsearch.username: elastic
xpack.monitoring.elasticsearch.password: dinpay
xpack.monitoring.elasticsearch.url: ["http://127.0.0.1:9200"]

四、filebeat安装及配置

wget https://artifacts.elastic.co/downloads/beats/filebeat/https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-6.4.0-linux-x86_64.tar.gz

tar -xf filebeat-6.4.0-linux-x86_64.tar.gz

cd filebeat-6.4.0-linux-x86_64

配置 filebeat.yml

• type: log
  paths:

  • /var/log/nginx/access.log

output.logstash:

hosts: ["192.168.12.81:5044"]

xpack.monitoring:
enabled: true
elasticsearch:
hosts: ["http://192.168.12.81:9200", "http://192.168.12.81:9200"]
username: elastic
password: dinpay

五、Nginx 日志格式配置：

log_format json '{"@timestamp":"$time_iso8601",'
'"host":"$server_addr",'
'"clientip":"$clientRealIp",'
'"remote_user":"$remote_user",'
'"request":"$request",'
'"http_user_agent":"$http_user_agent",'
'"size":$body_bytes_sent,'
'"responsetime":$request_time,'
'"upstreamtime":"$upstream_response_time",'
'"upstreamhost":"$upstream_addr",'
'"http_host":"$host",'
'"url":"$uri",'
'"domain":"$host",'
'"xff":"$http_x_forwarded_for",'
'"referer":"$http_referer",'
'"status":"$status",'
'"ss":"$upstream_status"}';

access_log  /var/log/nginx/access.log  json;

map $http_x_forwarded_for $clientRealIp {

""  $remote_addr;

~^(?P<firstAddr>[0-9\.]+),?.*$    $firstAddr;

}
