ELK介绍
ELK Stack （5.0版本之后） Elastic Stack == （ELK Stack + Beats）
ELK Stack包含：ElasticSearch、Logstash、Kibana
ElasticSearch是一个搜索引擎，用来搜索、分析、存储日志。它是分布式的，也就是说可以横向扩容，可以自动发现，索引自动分片，总之很强大。文档https://www.elastic.co/guide/cn/elasticsearch/guide/current/index.html
Logstash用来采集日志，把日志解析为json格式交给ElasticSearch。
Kibana是一个数据可视化组件，把处理后的结果通过web界面展示
Beats在这里是一个轻量级日志采集器，其实Beats家族有5个成员
早期的ELK架构中使用Logstash收集、解析日志，但是Logstash对内存、cpu、io等资源消耗比较高。相比 Logstash，Beats所占系统的CPU和内存几乎可以忽略不计
x-pack对Elastic Stack提供了安全、警报、监控、报表、图表于一身的扩展包，是收费的
ELK架构
ELK安装 – 准备工作
准备3台机器130,132,133
角色划分：
3台全部安装elasticsearch(后续简称es) ，1主节点130,2数据节点132,133
es主130上安装kibana
1台es数据节点132上安装logstash 3台机器全部安装jdk8（openjdk即可）
yum install -y java-1.8.0-openjdk
ELK安装 – 安装es
以下操作3台机器上都要执行
rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
vim /etc/yum.repos.d/elastic.repo //加入如下内容
[elasticsearch-6.x]
name=Elasticsearch repository for 6.x packages
gpgcheck=1
enabled=1
autorefresh=1
type=rpm-md
yum install -y elasticsearch //也可以直接下载rpm文件，然后安装
rpm -ivh elasticsearch-6.0.0.rpm
ELK安装 – 配置es
elasticsearch配置文件/etc/elasticsearch和/etc/sysconfig/elasticsearch
在130上编辑配置文件vim /etc/elasticsearch/elasticsearch.yml//增加或更改
cluster.name: weifenglinux
node.master: true//意思是该节点为主节点
node.data: false
network.host: 0.0.0.0
discovery.zen.ping.unicast.hosts: ["192.168.133.130", "192.168.133.132", "192.168.133.133"]
配置实例：
[root@weifeng678 ~]# cat /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:
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: ywkd123
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: ywkd01
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
node.master: true
node.data: false
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /var/lib/elasticsearch
#
# Path to log files:
#
path.logs: /var/log/elasticsearch
#
# ----------------------------------- 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: 0.0.0.0
#
# 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: ["192.168.4.81", "192.168.4.82","192.168.4.83"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes:
#
# 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 -----------------------------------

},
curl -XDELETE 'localhost:9200/logstash-xxx-*' 可以删除指定索引
浏览器访问192.168.132.130:5601，到kibana配置索引
左侧点击“Managerment”-> “Index Patterns”-> “Create Index Pattern”
Index pattern这里需要根据前面curl查询到的索引名字来写，否则下面的按钮是无法点击的
再点击 index 可以查看系统的日志，如没有信息被搜索到 可调整时间间隔来尝试
logstash收集nginx日志
132上 编辑配置文件 vim /etc/logstash/conf.d/nginx.conf//加入如下内容
input {
file {
path => "/tmp/elk_access.log"
start_position => "beginning"
type => "nginx"
}
}
filter {
grok {
match => { "message" => "%{IPORHOST:http_host} %{IPORHOST:clientip} - %{USERNAME:remote_user} [%{HTTPDATE:timestamp}] "(?:%{WORD:http_verb} %{NOTSPACE:http_request}(?: HTTP/%{NUMBER:http_version})?|%{DATA:raw_http_request})" %{NUMBER:response} (?:%{NUMBER:bytes_read}|-) %{QS:referrer} %{QS:agent} %{QS:xforwardedfor} %{NUMBER:request_time:float}"}
}
geoip {

elasticsearch {
hosts => ["192.168.133.132:9200"]
index => "nginx-test-%{+YYYY.MM.dd}"
}
}
以下在132上操作
检测配置文件是否有错
cd /usr/share/logstash/bin
./logstash --path.settings /etc/logstash/ -f /etc/logstash/conf.d/nginx.conf --config.test_and_exit
yum install -y nginx
vim /etc/nginx/conf.d/elk.conf//写入如下内容
server {
listen 80;
server_name elk.weifeng.com;
location / {
proxy_pass http://192.168.133.130:5601;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
access_log /tmp/elk_access.log main2;
}
实际配置内容：
[root@localhost ~]# cat /etc/nginx/conf.d/elk.conf
server {
listen 80;
server_name 192.168.4.83;
location / {
proxy_pass http://192.168.4.81:5601;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
access_log /tmp/elk_access.log main2;
}
以下在132上操作
vim /etc/nginx/nginx.conf//增加如下内容
log_format main2 '$http_host $remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$upstream_addr" $request_time';
nginx -t
systemctl start nginx
绑定hosts 192.168.133.132 elk.weifeng.com
浏览器访问，检查是否有日志产生
systemctl restart logstash
130上curl 'localhost:9200/_cat/indices?v'
实际操作：
[root@localhost ~]# curl '192.168.4.81:9200/_cat/indices?v'
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size
green open .kibana TXIUAJVJTA2F-2rRPq-EQQ 1 1 3 1 34.5kb 18.6kb

检查是否有nginx-test开头的索引生成
如果有，才能到kibana里去配置该索引
左侧点击“Managerment”-> “Index Patterns”-> “Create Index Pattern”
Index pattern这里写nginx-test-*
之后点击左侧的Discover
使用Beats采集日志
filebeat metricbeat packetbeat winlogbeat auditbeat heartbeat
可扩展，支持自定义构建
在133上执行
rpm -ivh filebeat-6.0.0-x86_64.rpm
首先编辑配置文件
vim /etc/filebeat/filebeat.yml //增加或者更改
filebeat.prospectors:
- type: log
paths:
- /var/log/messages
output.console:

# For more available modules and options, please see the filebeat.reference.yml sample
# configuration file.
#=========================== Filebeat prospectors =============================
filebeat.prospectors:
# Each - is a prospector. Most options can be set at the prospector level, so
