ELK
一、ELK介绍
ELK是3个开源软件的缩写，分别为Elasticsearch 、 Logstash和Kibana , 它们都是开源软件。不过现在还新增了一个Beats，它是一个轻量级的日志收集处理工具（Agent），Beats占用资源少，适合于在各个服务器上搜集日志后传输给Logstash，官方也推荐此工具，目前由于原本的ELK Stack成员中加入了Beats工具所以已改名为Elastic Stack。
Elasticsearch是个开源分布式搜索引擎，提供搜集、分析、存储数据3大功能。它的特点有：分布式，零配置，自动发现，索引自动分片，索引副本机制，restful风格接口，多数据源，自动搜索负载等。
Logstash主要是用来日志的搜集、分析、过滤日志的工具，支持大量的数据获取方式。一般工作方式为c/s架构，Client端安装在需要收集日志的主机上，server端负责将收到的各节点日志进行过滤、修改等操作在一并发往Elasticsearch上去。
Kibana也是一个开源和免费的工具，Kibana可以为 Logstash和 ElasticSearch提供的日志分析友好的 Web 界面，可以帮助汇总、分析和搜索重要数据日志。
Beats在这里是一个轻量级日志采集器，其实Beats家族有6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。
二、基础环境
1.（虚拟机）规划三个节点，一个为主节点，两个为数据节点：
主机名：elk--1 节点IP：192.168.233.201 节点规划：Elasticsearch+Kibana（主）
主机名：elk--2 节点IP：192.168.233.202 节点规划：Elasticsearch+Logstash（数据）
主机名：elk--3 节点IP：192.168.233.203 节点规划：Elasticsearch（数据）
2.修改主机名：
elk_1节点：
[root@localhost ~]# hostnamectl set-hostname elk--1
[root@localhost ~]# bash
[root@elk--1 ~]#
elk_2节点：
[root@localhost ~]# hostnamectl set-hostname elk--2
[root@localhost ~]# bash
[root@elk--2 ~]#
elk_3节点：
[root@localhost ~]# hostnamectl set-hostname elk--3
[root@localhost ~]# bash
[root@elk--3 ~]#
3.配置hosts文件：
elk--1节点：
[root@elk--1 ~]# vi /etc/hosts
[root@elk--1 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.11 elk--1
192.168.100.12 elk--2
192.168.100.13 elk--3
elk--2节点：
[root@elk--2 ~]# vi /etc/hosts
[root@elk--2 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.11 elk--1
192.168.100.12 elk--2
192.168.100.13 elk--3
elk--3节点：
[root@elk--3 ~]# vi /etc/hosts
[root@elk--3~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.11 elk--1
192.168.100.12 elk--2
192.168.100.13 elk--3
4.yum安装
部署ELK环境需要jdk1.8以上的JDK版本软件环境，我们使用opnejdk1.8，3节点全部安装
[root@elk--1~]# yum install -y java-1.8.0-openjdk java-1.8.0-openjdk-devel vim net-tools wget
[root@elk--1~]# java -version
openjdk version "1.8.0_242"
OpenJDK Runtime Environment (build 1.8.0_242-b08)
OpenJDK 64-Bit Server VM (build 25.242-b08, mixed mode)
三、部署Elasticserach
1.下载 Elasticserach 三个节点都需要下载
下载 Elasticserach-6.0.0.rpm 包
[root@elk--1 ~]# wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.0.0.rpm
[root@elk--1 ~]# ls
anaconda-ks.cfg elasticsearch-6.0.0.rpm
2.安装 Elasticserach 三个节点都需要安装
[root@elk--1 ~]# rpm -ivh elasticsearch-6.0.0.rpm
// 参数含义：i表示安装，v表示显示安装过程，h表示显示进度
warning: elasticsearch-6.0.0.rpm: Header V4 RSA/SHA512 Signature, key ID d88e42b4: NOKEY
Preparing... ################################# [100%]

Updating / installing...
1:elasticsearch-0:6.0.0-1 ################################# [100%]
### NOT starting on installation, please execute the following statements to configure elasticsearch service to start automatically using systemd
sudo systemctl daemon-reload
sudo systemctl enable elasticsearch.service
### You can start elasticsearch service by executing
sudo systemctl start elasticsearch.service
3.配置 Elasticserach
elk--1节点（加蓝标深的是需要修改的地方）：
[root@elk_1 ~]# 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: ELK
//配置es的集群名称，默认是elasticsearch，es会自动发现在同一网段下的es，如果在同一网段下有多个集群，就可以用这个属性来区分不同的集群。
# ------------------------Node -----------------
# Use a descriptive name for the node:
node.name: elk-1
//节点名，默认随机指定一个name列表中名字，该列表在es的jar包中config文件夹里name.txt文件中，其中有很多作者添加的有趣名字。
node.master: true
//指定该节点是否有资格被选举成为node，默认是true，es是默认集群中的第一台机器为master，如果这台机挂了就会重新选举master。 其他两节点为false
node.data: false
//指定该节点是否存储索引数据，默认为true。其他两节点为true
# ----------------- Paths ----------------
# Path to directory where to store the data (separate multiple locations by comma):
path.data: /var/lib/elasticsearch
//索引数据存储位置(保持默认,不要开启注释)
# Path to log files:
path.logs: /var/log/elasticsearch
//设置日志文件的存储路径，默认是es根目录下的logs文件夹
# --------------- Network ------------------
# Set the bind address to a specific IP (IPv4 or IPv6):
network.host: 192.168.233.201
//设置绑定的ip地址，可以是ipv4或ipv6的，默认为0.0.0.0。
# Set a custom port for HTTP:
http.port: 9200
//启动的es对外访问的http端口，默认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"]
discovery.zen.ping.unicast.hosts: ["elk-1","elk-2","elk-3"]
//设置集群中master节点的初始列表，可以通过这些节点来自动发现新加入集群的节点。
elk--2节点：
[root@elk--2 ~]# vi /etc/elasticsearch/elasticsearch.yml
cluster.name: ELK
node.name: elk-2
node.master: false
node.data: true
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 192.168.233.202
http.port: 9200
discovery.zen.ping.unicast.hosts: ["elk-1","elk-2","elk-3"]
elk--3节点：
[root@elk--3 ~]# vi /etc/elasticsearch/elasticsearch.yml
cluster.name: ELK
node.name: elk-2
node.master: false
node.data: true
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 192.168.233.203
http.port: 9200
discovery.zen.ping.unicast.hosts: ["elk-1","elk-2","elk-3"]
4.启动服务
通过命令启动es服务，启动后使用ps命令查看进程是否存在或者使用netstat命令查看是否端口启动
三个节点都需要启动
[root@elk--1 ~]# systemctl start elasticsearch
[root@elk--1 ~]# ps -ef |grep elasticsearch
elastic+ 19280 1 0 09:00 ? 00:00:54 /bin/java -Xms1g -Xmx1g -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+AlwaysPreTouch -server -Xss1m -Djava.awt.headless=true -Dfile.encoding=UTF-8 -Djna.nosys=true -XX:-OmitStackTraceInFastThrow -Dio.netty.noUnsafe=true -Dio.netty.noKeySetOptimization=true -Dio.netty.recycler.maxCapacityPerThread=0 -Dlog4j.shutdownHookEnabled=false -Dlog4j2.disable.jmx=true -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/lib/elasticsearch -Des.path.home=/usr/share/elasticsearch -Des.path.conf=/etc/elasticsearch -cp /usr/share/elasticsearch/lib/* org.elasticsearch.bootstrap.Elasticsearch -p /var/run/elasticsearch/elasticsearch.pid --quiet
root 19844 19230 0 10:54 pts/0 00:00:00 grep --color=auto elasticsearch
[root@elk--1 ~]# netstat -lntp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1446/sshd
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1994/master

tcp6 0 0 :::22 :::* LISTEN 1446/sshd
tcp6 0 0 ::1:25 :::* LISTEN 1994/master
有以上端口或者进程存在，证明es服务启动成功
5.检查集群状态
使用curl命令来检查集群状态 elk_1 节点：
[root@elk--1 ~]# curl '192.168.233.201:9200/_cluster/health?pretty'
{
"cluster_name" : "ELK",
"status" : "green",
//为green则代表健康没问题，yellow或者red 则是集群有问题
"timed_out" : false,
//是否有超时
"number_of_nodes" : 3,
//集群中的节点数量
"number_of_data_nodes" : 2,
//集群中data节点的数量
"active_primary_shards" : 1,
"active_shards" : 2,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 0,
"delayed_unassigned_shards" : 0,
"number_of_pending_tasks" : 0,
"number_of_in_flight_fetch" : 0,
"task_max_waiting_in_queue_millis" : 0,
"active_shards_percent_as_number" : 100.0
}
四、部署 Kibana
下载部署nginx进行负载均衡
[root@elk-1 ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo[root@elk-1 ~]# yum install nginx -y
[root@elk-1 ~]# systemctl start nginx
[root@elk-1 ~]# vim /etc/nginx/nginx.conf
upstream elasticsearch {
zone elasticsearch 64K;
server elk-1:9200;
server elk-2:9200;
server elk-3:9200;
}
server {
listen 8080;
server_name 192.168.233.201;
location / {
proxy_pass http://elasticsearch;
proxy_redirect off;
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 /var/log/es_access.log;
}
1.在主节点下载安装 Kibana
[root@elk--1 ~]# wget https://artifacts.elastic.co/downloads/kibana/kibana-6.0.0-x86_64.rpm
[root@elk--1 ~]# rpm -ivh kibana-6.0.0-x86_64.rpm
warning: kibana-6.0.0-x86_64.rpm: Header V4 RSA/SHA512 Signature, key ID d88e42b4: NOKEY
Preparing... ################################# [100%]
Updating / installing...
1:kibana-6.0.0-1 ################################# [100%]
2.配置 Kibana
[root@elk--1 ~]# vim /etc/kibana/kibana.yml
server.port: 5601
server.host: "192.168.233.201"
elasticsearch.url: "http://192.168.233.201:9200"
4.启动 Kibana
[root@elk--1 ~]# systemctl start kibana
[root@elk--1 ~]# ps -ef |grep kibana
kibana 19958 1 41 11:26 ? 00:00:03 /usr/share/kibana/bin/../node/bin/node --no-warnings /usr/share/kibana/bin/../src/cli -c /etc/kibana/kibana.yml
root 19970 19230 0 11:26 pts/0 00:00:00 grep --color=auto kibana
[root@elk--1 ~]# netstat -lntp |grep node
tcp 0 0 192.168.233.201:5601 0.0.0.0:* LISTEN 19958/node
启动成功后网页访问，可以访问到如下界面。http://192.168.233.201:5601 访问的这个页面
五、部署 Logstash
1. 在elk--2节点下载安装 Logstash
[root@elk--2 ~]# wget https://artifacts.elastic.co/downloads/logstash/logstash-6.0.0.rpm
[root@elk--2 ~]# rpm -ivh logstash-6.0.0.rpm
warning: logstash-6.0.0.rpm: Header V4 RSA/SHA512 Signature, key ID d88e42b4: NOKEY
Preparing... ################################# [100%]
Updating / installing...
1:logstash-1:6.0.0-1 ################################# [100%]
Using provided startup.options file: /etc/logstash/startup.options
2. 配置 Logstash
修改增加如下：
[root@elk--2 ~]# vim /etc/logstash/logstash.yml
http.host: "192.168.233.202"
配置logstash收集syslog日志：
[root@elk--2 ~]# vim /etc/logstash/conf.d/syslog.conf
input {
file {
path => "/var/log/messages"
type => "systemlog"
start_position => "beginning"
stat_interval => "3"
}
}
output {
elasticsearch {
hosts => ["192.168.233.201:9200","192.168.233.202:9200","192.168.233.203:9200"]
index => "system-log-%{+YYYY.MM.dd}"
}
}
检测配置文件是否错误：
[root@elk--2 ~]# ln -s /usr/share/logstash/bin/logstash /usr/bin
// 创建软连接，方便使用logstash命令
[root@elk--2 ~]# logstash --path.settings /etc/logstash/ -f /etc/logstash/conf.d/syslog.conf --config.test_and_exit
Sending Logstash's logs to /var/log/logstash which is now configured via log4j2.properties
Configuration OK
// 为ok则代表没问题
3. 授权
[root@elk--2 ~]# chmod 755 /var/log/messages
[root@elk--2 ~]# chown -R logstash /var/lib/logstash/
4. 启动 logstash
检查配置文件没有问题后，启动Logstash服务：
[root@elk_2 ~]# systemctl start logstash
使用ps命令，查看进程：
[root@elk--2 ~]# ps -ef |grep logstash
logstash 21835 1 12 16:45 ? 00:03:01 /bin/java -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+DisableExplicitGC -Djava.awt.headless=true -Dfile.encoding=UTF-8 -XX:+HeapDumpOnOutOfMemoryError -Xmx1g -Xms256m -Xss2048k -Djffi.boot.library.path=/usr/share/logstash/vendor/jruby/lib/jni -Xbootclasspath/a:/usr/share/logstash/vendor/jruby/lib/jruby.jar -classpath : -Djruby.home=/usr/share/logstash/vendor/jruby -Djruby.lib=/usr/share/logstash/vendor/jruby/lib -Djruby.script=jruby -Djruby.shell=/bin/sh org.jruby.Main /usr/share/logstash/lib/bootstrap/environment.rb logstash/runner.rb --path.settings /etc/logstash
root 21957 20367 0 17:10 pts/2 00:00:00 grep --color=auto logstash
使用netstat命令，查看进程端口：
[root@elk--2 ~]# netstat -lntp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 957/sshd
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1152/master
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 7390/nginx: master
tcp6 0 0 :::10514 :::* LISTEN 7403/java
tcp6 0 0 192.168.233.202:9300 :::* LISTEN 6418/java
tcp6 0 0 :::22 :::* LISTEN 957/sshd
tcp6 0 0 ::1:25 :::* LISTEN 1152/master
tcp6 0 0 192.168.233.202:9600 :::* LISTEN 7403/java
tcp6 0 0 192.168.233.202:9200 :::* LISTEN 6418/java
主要查看9600 端口
5. Kibana 上查看日志
之前部署Kibana完成后，还没有检索日志。现在Logstash部署完成，我们回到Kibana服务器上查看日志索引，执行命令如下：
[root@elk--1 ~]# curl '192.168.233.201:9200/_cat/indices?v'
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size
green open system-syslog-2022.01 tAd3L8W6RHqDeRDOvOdrTA 5 1 10631 0 2.8mb 1.3mb
green open .kibana HJ8wt6BuQaeVcc5Vf1zbcg 1 1 3
6. Web 界面配置
浏览器访问192。168.233.201:5601，到 Kibana 上配置索引
复制下图黄色标注的地方 粘贴到Web界面
按完之后按、按Discover。出现的这个是乱码显现
跟着下图走就可以解决乱码了
这就是正常界面
六、Logstash 收集 Nginx 日志
1.下载安装Nginx
[root@elk--2 ~]# wget http://nginx.org/packages/centos/7/x86_64/RPMS/nginx-1.16.1-1.el7.ngx.x86_64.rpm
[root@elk--2 ~]# rpm -ivh nginx-1.16.1-1.el7.ngx.x86_64.rpm
警告：nginx-1.16.1-1.el7.ngx.x86_64.rpm: 头V4 RSA/SHA1 Signature，密钥 ID 7bd9bf62: NOKEY

3. 配置 Logstash
在elk--2节点编辑nginx配置文件：
[root@elk--2 ~]# vim /etc/logstash/conf.d/nginx.conf
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 {
source => "clientip"
}
}
output {
stdout { codec => rubydebug }
elasticsearch {
hosts => ["192.168.233.202:9200"]
index => "nginx-test-%{+YYYY.MM.dd}"
}
}
使用logstash命令检查文件是否错误：
[root@elk--2 ~]# logstash --path.settings /etc/logstash/ -f /etc/logstash/conf.d/nginx.conf --config.test_and_exit
Sending Logstash's logs to /var/log/logstash which is now configured via log4j2.properties
Configuration OK
编辑监听Nginx日志配置文件，加入如下内容：
# 不移走这个文件就 elk.conf 就执不了。因为这个文件也是 80 端口
[root@elk--2 ~]# mv /etc/nginx/conf.d/default.conf /tmp/
[root@elk--2 ~]#vim /etc/nginx/conf.d/elk.conf
server {
listen 80;
server_name elk.com;
location / {
proxy_pass http://192.168.233.201:5601;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
access_log /tmp/elk_access.log main2;
}
修改Nginx日志配置文件，增加如下内容（需注意Nginx配置文件格式）：
[root@elk--2 ~]# vim /etc/nginx/nginx.confhttp {
include /etc/nginx/mime.types;
default_type application/octet-stream;
# log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#插入这些加蓝代码
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';
access_log /var/log/nginx/access.log main2;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
[root@elk--2 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
启动
[root@elk-2 ~]# systemctl restart logstash
在/etc/hosts文件中添加下面信息
192.168.100.30 elk.com
浏览器访问，检查是否有日志产生
4. Web 页面配置
浏览器访问192.168.233.201:5601，到Kibana上配置索引：
查看elk--1主节点收到没有
[root@elk--1 ~]# curl '192.168.233.201:9200/_cat/indices?v'
health status index uuid pri rep d
green open system-syslog-2022.01 tAd3L8W6RHqDeRDOvOdrTA 5 1
green open nginx-test-2022.01.14 vzFiklXgRP-GenN_KMe87A 5 1
green open .kibana HJ8wt6BuQaeVcc5Vf1zbcg 1 1
跟着点击即可，如果出现乱码显现就去修改他的时间
七、Beats采集日志
