快速搭建应用服务日志收集系统(Filebeat + ElasticSearch + kibana)

概要说明

需求场景，系统环境是CentOS，多个应用部署在多台服务器上，平时查看应用日志及排查问题十分不变。索性搭建一个服务器日志收集系统，由于每日日志规模仅在G级别，所有前期暂先不搭建集群。 
技术方案是 Filebeat + ElasticSearch + kibana (日志服务器上安装ElasticSearch,Kibana,其他应用服务器上安装Filebeat); 没有考虑加上Logstash,Flume，Kafka，Redis等，一是Filebeat比较轻量级，占用资源少，且可直接将日志输出到elasticsearch,仅是方便查看线上服务日志；不需要对日志字段进行解析，所以不打算引入技术太多，增加复杂性；没用Redis,原因仅是当前已有Redis集群，但主要是交易系统使用，不想增加其额外风险。
另外，当前的选用的日志服务器内存等配置不高。不适合安装过多软件，仅此而已。


也可参考我之前写的另一篇博客：
Windows下ELK-5.4.3环境搭建 http://www.cnblogs.com/huligong1234/p/7108109.html

一、安装ElasticSearch

1.安装JDK8环境

[root@app-001 src]# cd /usr/local/src/
[root@app-001 src]# rpm -qa | grep jdk
java-1.6.0-openjdk-1.6.0.41-1.13.13.1.el6_8.x86_64
[root@app-001 src]# rpm -e java-1.6.0-openjdk-1.6.0.41-1.13.13.1.el6_8.x86_64
[root@app-001 src]# curl -L -O http://download.oracle.com/otn-pub/java/jdk/8u144-b01/090f390dda5b47b9b721c7dfaa008135/jdk-8u144-linux-x64.rpm?AuthParam=1506173332_32b98eb52c8955419974ec3efcba2209
[root@app-001 src]# rpm -ivh jdk-8u144-linux-x64.rpm
[root@app-001 src]# java -version

2.安装ElasticSearch

[root@app-001 src]# curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.6.1.rpm
[root@app-001 src]# rpm -ivh elasticsearch-5.6.1.rpm
[root@app-001 src]# chkconfig --add elasticsearch

3.配置ElasticSearch

[root@app-001 src]# vi /etc/elasticsearch/elasticsearch.yml

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
#cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /data/elasticsearch/data
#
# Path to log files:
#
#path.logs: /data/elasticsearch/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
bootstrap.memory_lock: true

#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 192.168.1.106
#
# Set a custom port for HTTP:
#
http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.zen.ping.unicast.hosts: ["host1", "host2"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes: 3
#
# For more information, consult the zen discovery module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
http.cors.enabled: true
http.cors.allow-origin: "*"
#http.cors.allow-origin: "esmgr.domain.com"

注意：如果CentOS版本低于7.0还需要进行如下配置调整

bootstrap.memory_lock: false
bootstrap.system_call_filter: false

4.启动ElasticSearch

[root@app-001 src]# service elasticsearch start
[root@app-001 src]# curl "http://192.168.1.234:9200" #查看启动情况

5.防火墙放开iptables 9200端口，允许内网其他机器访问

[root@app-001 src]# vi /etc/sysconfig/iptables
增加如下内容：
-A INPUT -s 192.168.1.0/24 -p tcp -m state --state NEW -m tcp --dport 9200 -j ACCEPT

[root@app-001 src]# service iptables restart

二、安装Filebeat

1.下载

[root@app-001 src]# curl -L -O https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-5.6.1-x86_64.rpm

2.安装

[root@app-001 src]# rpm -ivh filebeat-5.6.1-x86_64.rpm
[root@app-001 src]# chkconfig --add filebeat

3.配置

[root@app-001 src]# vi /etc/filebeat/filebeat.yml

###################### Filebeat Configuration Example #########################

# This file is an example configuration file highlighting only the most common
# options. The filebeat.full.yml file from the same directory contains all the
# supported options with more comments. You can use it as a reference.
#
# You can find the full configuration reference here:
# https://www.elastic.co/guide/en/beats/filebeat/index.html

#=========================== Filebeat prospectors =============================

filebeat.prospectors:

# Each - is a prospector. Most options can be set at the prospector level, so
# you can use different prospectors for various configurations.
# Below are the prospector specific configurations.

- input_type: log

# Paths that should be crawled and fetched. Glob based paths.
paths:
#- /var/log/*.log
- /opt/tomcat-myapp/logs/myapp.log

# Include lines. A list of regular expressions to match. It exports the lines that are
# matching any regular expression from the list.
#include_lines: ["^ERR", "^WARN"]

# Exclude files. A list of regular expressions to match. Filebeat drops the files that
# are matching any regular expression from the list. By default, no files are dropped.
#exclude_files: [".gz$"]

# Optional additional fields. These field can be freely picked
# to add additional information to the crawled log files for filtering
#fields:
# level: debug
# review: 1

### Multiline options

# Mutiline can be used for log messages spanning multiple lines. This is common
# for Java Stack Traces or C-Line Continuation

# The regexp Pattern that has to be matched. The example pattern matches all lines starting with [
multiline.pattern: ^\[

# Defines if the pattern set under pattern should be negated or not. Default is false.
#multiline.negate: false

# Match can be set to "after" or "before". It is used to define if lines should be append to a pattern
# that was (not) matched before or after or as long as a pattern is not matched based on negate.
# Note: After is the equivalent to previous and before is the equivalent to to next in Logstash
multiline.match: after
encoding: utf-8

elasticsearch.url: "http://192.168.1.106:9200"

4.启动

[root@app-001 src]# service kibana start

浏览器访问 http://192.168.1.106:5601/

四、安装插件

1.elasticsearch-head

1.1.安装NodeJS环境

[root@app-001 src]# curl --silent --location https://rpm.nodesource.com/setup_8.x | bash -
[root@app-001 src]# yum install -y nodejs
[root@app-001 src]# node -v 
[root@app-001 src]# npm -v

1.2.下载 elasticsearch-head

[root@app-001 src]# wget https://codeload.github.com/mobz/elasticsearch-head/zip/master
[root@app-001 src]# unzip master

1.3.修改配置

1.3.1.修改elasticsearch.yml，增加跨域的配置(需要重启es才能生效)
http.cors.enabled: true
http.cors.allow-origin: "*"

1.3.2.编辑elasticsearch-head/Gruntfile.js，修改服务器监听地址，connect节点增加hostname属性，将其值设置为*

connect: {
    server: {
        options: {
            hostname:'*',
            port: 9100,
            base: '.',
            keepalive: true
        }
    }
}

1.3.3.编辑elasticsearch-head/_site/app.js,
修改默认es地址http://localhost:9200/为http://192.168.1.106:9200/。

1.4.启动

[root@app-001 src]# npm run start
浏览器访问 http://192.168.1.106:9100/

2.bigdesk

http://bigdesk.org/

五、使用Basic Auth给ElasticSearch和Kibana配置访问权限

1.创建密码

[root@app-001 src]# htpasswd -c /usr/local/tengine/db/passwd.db loguser

2.修改Nginx配置文件nginx.conf

[root@app-001 src]# vi /usr/local/tengine/conf/nginx.conf

        server {
            listen          80;
            server_name     esmgr.domain.com;
            auth_basic "basic auth esmgr";
            auth_basic_user_file /usr/local/nginx/db/passwd.db;
            location / { 
                proxy_pass        http://192.168.1.106:9200; 
            }
            location /head/ {
                proxy_pass    http://192.168.1.106:9100/; 
            }
        }

3.更新Nginx生效

[root@app-001 src]# /usr/local/tengine/sbin/nginx -t
nginx: the configuration file /usr/local/tengine/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/tengine/conf/nginx.conf test is successful
[root@app-001 src]# /usr/local/tengine/sbin/nginx -s reload

六、CURL查询方式示例

curl -XGET "http://192.168.1.106:9200/_search" -H 'Content-Type: application/json' -d'
{
  "query": {
    "match": {"message": "JD_08011137015349778"}
  }
}'

curl -XGET "http://192.168.1.106:9200/_search" -H 'Content-Type: application/json' -d'
{
  "query": {

    "match": {"log_type": "myapp"}
  },"size": 5
}'

curl -XGET "http://192.168.1.106:9200/_search" -H 'Content-Type: application/json' -d'
{"query":{"bool":{"must":[{"match":{"message":"JD_08011137015349778"}}],"filter":[{"range":{"@timestamp":{"from":"now-1d","to":"now"}}}]}}}
'

curl -XGET "http://192.168.1.106:9200/_search" -H 'Content-Type: application/json' -d'
{"query":{"bool":{"must":[{"match":{"message":"JD_08011137015349778"}}],"filter":[{"range":{"@timestamp":{"gte":"1506441600000","lte":"1506527999000"}}}]}}}
'

七、Java HttpClient 方式调用简单封装示例

package org.jeedevframework.common.es;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

import javax.servlet.http.HttpServletRequest;

import org.apache.commons.lang3.StringUtils;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.params.BasicHttpParams;
import org.apache.http.params.HttpConnectionParams;
import org.apache.http.util.EntityUtils;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

import org.jeedevframework.util.DateUtil;
/**
针对如下CURL请求方式的Java封装示例
curl -XGET "http://192.168.1.106:9200/_search" -H 'Content-Type: application/json' -d'
{"query":{"bool":{"must":[{"match":{"message":"JD_08011137015349778"}}],
"filter":[{"range":{"@timestamp":{"gte":"1506441600000","lte":"1506527999000"}}}]}}}
