      一套好的日志分析系统可以详细记录系统的运行情况，方便我们定位分析系统性能瓶颈、查找定位系统问题。上一篇说明了日志的多种业务场景以及日志记录的实现方式，那么日志记录下来，相关人员就需要对日志数据进行处理与分析，基于E(ElasticSearch)L(Logstash)K(Kibana)组合的日志分析系统可以说是目前各家公司普遍的首选方案。

    • Elasticsearch: 分布式、RESTful 风格的搜索和数据分析引擎，可快速存储、搜索、分析海量的数据。在ELK中用于存储所有日志数据。

    • Logstash： 开源的数据采集引擎，具有实时管道传输功能。Logstash 能够将来自单独数据源的数据动态集中到一起，对这些数据加以标准化并传输到您所选的地方。在ELK中用于将采集到的日志数据进行处理、转换然后存储到Elasticsearch。

    • Kibana： 免费且开放的用户界面，能够让您对 Elasticsearch 数据进行可视化，并让您在 Elastic Stack 中进行导航。您可以进行各种操作，从跟踪查询负载，到理解请求如何流经您的整个应用，都能轻松完成。在ELK中用于通过界面展示存储在Elasticsearch中的日志数据。

      作为微服务集群，必须要考虑当微服务访问量暴增时的高并发场景，此时系统的日志数据同样是爆发式增长，我们需要通过消息队列做流量削峰处理，Logstash官方提供Redis、Kafka、RabbitMQ等输入插件。Redis虽然可以用作消息队列，但其各项功能显示不如单一实现的消息队列，所以通常情况下并不使用它的消息队列功能；Kafka的性能要优于RabbitMQ，通常在日志采集，数据采集时使用较多，所以这里我们采用Kafka实现消息队列功能。
      ELK日志分析系统中，数据传输、数据保存、数据展示、流量削峰功能都有了，还少一个组件，就是日志数据的采集，虽然log4j2可以将日志数据发送到Kafka，甚至可以将日志直接输入到Logstash，但是基于系统设计解耦的考虑，业务系统运行不会影响到日志分析系统，同时日志分析系统也不会影响到业务系统，所以，业务只需将日志记录下来，然后由日志分析系统去采集分析即可，Filebeat是ELK日志系统中常用的日志采集器，它是 Elastic Stack 的一部分，因此能够与 Logstash、Elasticsearch 和 Kibana 无缝协作。

    • Kafka： 高吞吐量的分布式发布订阅消息队列，主要应用于大数据的实时处理。

    • Filebeat: 轻量型日志采集器。在 Kubernetes、Docker 或云端部署中部署 Filebeat，即可获得所有的日志流：信息十分完整，包括日志流的 pod、容器、节点、VM、主机以及自动关联时用到的其他元数据。此外，Beats Autodiscover 功能可检测到新容器，并使用恰当的 Filebeat 模块对这些容器进行自适应监测。

    软件下载：

      因经常遇到在内网搭建环境的问题，所以这里习惯使用下载软件包的方式进行安装，虽没有使用Yum、Docker等安装方便，但是可以对软件目录、配置信息等有更深的了解，在后续采用Yum、Docker等方式安装时，也能清楚安装了哪些东西，安装配置的文件是怎样的，即使出现问题，也可以快速的定位解决。

    Elastic Stack全家桶下载主页： https://www.elastic.co/cn/downloads/

    我们选择如下版本：

    Kafka下载：

    安装配置：

      安装前先准备好三台CentOS7服务器用于集群安装，这是IP地址为：172.16.20.220、172.16.20.221、172.16.20.222，然后将上面下载的软件包上传至三台服务器的/usr/local目录。因服务器资源有限，这里所有的软件都安装在这三台集群服务器上，在实际生产环境中，请根据业务需求设计规划进行安装。
      在集群搭建时，如果能够编写shell安装脚本就会很方便，如果不能编写，就需要在每台服务器上执行安装命令，多数ssh客户端提供了多会话同时输入的功能，这里一些通用安装命令可以选择启用该功能。

    一、安装Elasticsearch集群

    1、Elasticsearch是使用Java语言开发的，所以需要在环境上安装jdk并配置环境变量。

    新建/usr/local/java目录

    mkdir /usr/local/java

    将下载的jdk软件包jdk-8u64-linux-x64.tar.gz上传到/usr/local/java目录，然后解压

    tar -zxvf jdk-8u77-linux-x64.tar.gz

    配置环境变量/etc/profile

    vi /etc/profile

    在底部添加以下内容

    JAVA_HOME=/usr/local/java/jdk1.8.0_64
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar
export PATH JAVA_HOME CLASSPATH

    使环境变量生效

    source /etc/profile
    • 另外一种十分快捷的方式，如果不是内网环境，可以直接使用命令行安装，这里安装的是免费版本的openjdk
    yum install java-1.8.0-openjdk* -y
    2、安装配置Elasticsearch
    • 进入/usr/local目录，解压Elasticsearch安装包，请确保执行命令前已将环境准备时的Elasticsearch安装包上传至该目录。
    tar -zxvf elasticsearch-8.0.0-linux-x86_64.tar.gz
    • 重命名文件夹
    mv elasticsearch-8.0.0 elasticsearch
    • elasticsearch不能使用root用户运行，这里创建运行elasticsearch的用户组和用户
    # 创建用户组
groupadd elasticsearch
# 创建用户并添加至用户组
useradd elasticsearch -g elasticsearch
# 更改elasticsearch密码，设置一个自己需要的密码，这里设置为和用户名一样：El12345678
passwd elasticsearch
    • 新建elasticsearch数据和日志存放目录，并给elasticsearch用户赋权限
    mkdir -p /data/elasticsearch/data
mkdir -p /data/elasticsearch/log
chown -R elasticsearch:elasticsearch /data/elasticsearch/*
chown -R elasticsearch:elasticsearch /usr/local/elasticsearch/*
    • elasticsearch默认启用了x-pack，集群通信需要进行安全认证，所以这里需要用到SSL证书。注意：这里生成证书的命令只在一台服务器上执行，执行之后copy到另外两台服务器的相同目录下。
    # 提示输入密码时，直接回车
./elasticsearch-certutil ca -out /usr/local/elasticsearch/config/elastic-stack-ca.p12

# 提示输入密码时，直接回车
./elasticsearch-certutil cert --ca /usr/local/elasticsearch/config/elastic-stack-ca.p12 -out /usr/local/elasticsearch/config/elastic-certificates.p12 -pass ""
# 如果使用root用户生成的证书，记得给elasticsearch用户赋权限
chown -R elasticsearch:elasticsearch /usr/local/elasticsearch/config/elastic-certificates.p12
    • 设置密码，这里在出现输入密码时，所有的都是输入的123456
    ./elasticsearch-setup-passwords interactive

Enter password for [elastic]: 
Reenter password for [elastic]: 
Enter password for [apm_system]: 
Reenter password for [apm_system]: 
Enter password for [kibana_system]: 
Reenter password for [kibana_system]: 
Enter password for [logstash_system]: 
Reenter password for [logstash_system]: 
Enter password for [beats_system]: 
Reenter password for [beats_system]: 
Enter password for [remote_monitoring_user]: 
Reenter password for [remote_monitoring_user]: 
Changed password for user [apm_system]
Changed password for user [kibana_system]
Changed password for user [kibana]
Changed password for user [logstash_system]
Changed password for user [beats_system]
Changed password for user [remote_monitoring_user]
Changed password for user [elastic]
    • 修改elasticsearch配置文件
    vi /usr/local/elasticsearch/config/elasticsearch.yml

    # 修改配置
# 集群名称
cluster.name: log-elasticsearch
# 节点名称
node.name: node-1
# 数据存放路径
path.data: /data/elasticsearch/data
 # 日志存放路径
path.logs: /data/elasticsearch/log
# 当前节点IP
network.host: 192.168.60.201
 # 对外端口
http.port: 9200
# 集群ip
discovery.seed_hosts: ["172.16.20.220", "172.16.20.221", "172.16.20.222"]
# 初始主节点
cluster.initial_master_nodes: ["node-1", "node-2", "node-3"]
# 新增配置
# 集群端口
transport.tcp.port: 9300
transport.tcp.compress: true

http.cors.enabled: true
http.cors.allow-origin: "*" 
http.cors.allow-methods: OPTIONS, HEAD, GET, POST, PUT, DELETE
http.cors.allow-headers: "X-Requested-With, Content-Type, Content-Length, X-User"

xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: elastic-certificates.p12
    • 配置Elasticsearch的JVM参数
    vi /usr/local/elasticsearch/config/jvm.options

    -Xms1g
-Xmx1g
    • 修改Linux默认资源限制数
    vi /etc/security/limits.conf 

    # 在最后加入，修改完成后，重启系统生效。
*                soft    nofile          131072
*                hard   nofile          131072


    vi /etc/sysctl.conf
# 将值vm.max_map_count值修改为655360
vm.max_map_count=655360
# 使配置生效
sysctl -p
    • 切换用户启动服务
    su elasticsearch
cd /usr/local/elasticsearch/bin
# 控制台启动命令，可以看到具体报错信息
./elasticsearch

    • 访问我们的服务器地址和端口,可以看到，服务已启动：
      http://172.16.20.220:9200/
      http://172.16.20.221:9200/
      http://172.16.20.222:9200/


      elasticsearch服务已启动
    • 正常运行没有问题后，Ctrl+c关闭服务，然后使用后台启动命令
    ./elasticsearch -d

    备注：后续可通过此命令停止elasticsearch运行

    # 查看进程id
ps -ef | grep elastic
# 关闭进程
kill -9 1376(进程id)
    3、安装ElasticSearch界面管理插件elasticsearch-head，只需要在一台服务器上安装即可，这里我们安装到172.16.20.220服务器上
    # 解压
tar -xvJf node-v16.14.0-linux-x64.tar.xz
# 重命名
mv node-v16.14.0-linux-x64 nodejs
# 配置环境变量
vi /etc/profile
# 新增以下内容
export NODE_HOME=/usr/local/nodejs
PATH=$JAVA_HOME/bin:$NODE_HOME/bin:/usr/local/mysql/bin:/usr/local/subversion/bin:$PATH
export PATH JAVA_HOME NODE_HOME JENKINS_HOME CLASSPATH
# 使配置生效
source /etc/profile
# 测试是否配置成功
node -v

    # 解压
unzip elasticsearch-head-master.zip
# 重命名
mv elasticsearch-head-master elasticsearch-head
# 进入到elasticsearch-head目录
cd elasticsearch-head
#切换软件源，可以提升安装速度
npm config set registry https://registry.npm.taobao.org
# 执行安装命令
npm install -g npm@8.5.1
npm install phantomjs-prebuilt@2.1.16 --ignore-scripts
npm install
# 启动命令
npm run start

    二、安装Kafka集群

    • 环境准备：

      新建kafka的日志目录和zookeeper数据目录，因为这两项默认放在tmp目录，而tmp目录中内容会随重启而丢失,所以我们自定义以下目录:

     mkdir /data/zookeeper
 mkdir /data/zookeeper/data
 mkdir /data/zookeeper/logs

 mkdir /data/kafka
 mkdir /data/kafka/data
 mkdir /data/kafka/logs
    • zookeeper.properties配置
    vi /usr/local/kafka/config/zookeeper.properties

    修改如下：

    # 修改为自定义的zookeeper数据目录
dataDir=/data/zookeeper/data

# 修改为自定义的zookeeper日志目录
dataLogDir=/data/zookeeper/logs

# 端口
clientPort=2181

# 注释掉
#maxClientCnxns=0

# 设置连接参数，添加如下配置
# 为zk的基本时间单元，毫秒
tickTime=2000
# Leader-Follower初始通信时限 tickTime*10
initLimit=10
# Leader-Follower同步通信时限 tickTime*5
syncLimit=5

# 设置broker Id的服务地址，本机ip一定要用0.0.0.0代替
server.1=0.0.0.0:2888:3888
server.2=172.16.20.221:2888:3888
server.3=172.16.20.222:2888:3888
    • 在各台服务器的zookeeper数据目录/data/zookeeper/data添加myid文件，写入服务broker.id属性值

    在data文件夹中新建myid文件，myid文件的内容为1（一句话创建：echo 1 > myid）

    cd /data/zookeeper/data

vi myid

#添加内容：1 其他两台主机分别配置 2和3
1
    • kafka配置，进入config目录下，修改server.properties文件
    vi /usr/local/kafka/config/server.properties

    # 每台服务器的broker.id都不能相同
broker.id=1
# 是否可以删除topic
delete.topic.enable=true
# topic 在当前broker上的分片个数，与broker保持一致
num.partitions=3
# 每个主机地址不一样：
listeners=PLAINTEXT://172.16.20.220:9092
advertised.listeners=PLAINTEXT://172.16.20.220:9092
# 具体一些参数
log.dirs=/data/kafka/kafka-logs
# 设置zookeeper集群地址与端口如下：
zookeeper.connect=172.16.20.220:2181,172.16.20.221:2181,172.16.20.222:2181
    • Kafka启动

    kafka启动时先启动zookeeper，再启动kafka；关闭时相反，先关闭kafka，再关闭zookeeper。
    1、zookeeper启动命令

    ./zookeeper-server-start.sh ../config/zookeeper.properties &

    后台运行启动命令：

    nohup ./zookeeper-server-start.sh ../config/zookeeper.properties >/data/zookeeper/logs/zookeeper.log 2>1 &

    或者

    ./zookeeper-server-start.sh -daemon ../config/zookeeper.properties &

    查看集群状态：

    ./zookeeper-server-start.sh status ../config/zookeeper.properties

    2、kafka启动命令

    ./kafka-server-start.sh ../config/server.properties &

    后台运行启动命令：

    nohup bin/kafka-server-start.sh ../config/server.properties >/data/kafka/logs/kafka.log 2>1 &

    或者

     ./kafka-server-start.sh -daemon ../config/server.properties &

    3、创建topic，最新版本已经不需要使用zookeeper参数创建。

    ./kafka-topics.sh --create --replication-factor 2 --partitions 1 --topic test --bootstrap-server 172.16.20.220:9092

    参数解释:
    复制两份
    　　--replication-factor 2
    创建1个分区
    　　--partitions 1
    topic 名称
    　　--topic test

    4、查看已经存在的topic（三台设备都执行时可以看到）

    ./kafka-topics.sh --list --bootstrap-server 172.16.20.220:9092

    5、启动生产者：

    ./kafka-console-producer.sh --broker-list 172.16.20.220:9092 --topic test

    6、启动消费者：

    ./kafka-console-consumer.sh --bootstrap-server 172.16.20.221:9092 --topic test
./kafka-console-consumer.sh --bootstrap-server 172.16.20.222:9092 --topic test

    添加参数 --from-beginning 从开始位置消费，不是从最新消息

    ./kafka-console-consumer.sh --bootstrap-server 172.16.20.221 --topic test --from-beginning

    7、测试：在生产者输入test，可以在消费者的两台服务器上看到同样的字符test，说明Kafka服务器集群已搭建成功。

    三、安装配置Logstash

    Logstash没有提供集群安装方式，相互之间并没有交互，但是我们可以配置同属一个Kafka消费者组，来实现统一消息只消费一次的功能。

    • 解压安装包
    tar -zxvf logstash-8.0.0-linux-x86_64.tar.gz
mv logstash-8.0.0 logstash
    • 配置kafka主题和组
    cd logstash
# 新建配置文件
vi logstash-kafka.conf
# 新增以下内容
input {
  kafka {
    codec => "json"
    group_id => "logstash"
    client_id => "logstash-api"
    topics_pattern => "api_log"
    type => "api"
    bootstrap_servers => "172.16.20.220:9092,172.16.20.221:9092,172.16.20.222:9092"
    auto_offset_reset => "latest"
  }
  kafka {
    codec => "json"
    group_id => "logstash"
    client_id => "logstash-operation"
    topics_pattern => "operation_log"
    type => "operation"
    bootstrap_servers => "172.16.20.220:9092,172.16.20.221:9092,172.16.20.222:9092"
    auto_offset_reset => "latest"
  }
  kafka {
    codec => "json"
    group_id => "logstash"
    client_id => "logstash-debugger"
    topics_pattern => "debugger_log"
    type => "debugger"
    bootstrap_servers => "172.16.20.220:9092,172.16.20.221:9092,172.16.20.222:9092"
    auto_offset_reset => "latest"
  }
  kafka {
    codec => "json"
    group_id => "logstash"
    client_id => "logstash-nginx"
    topics_pattern => "nginx_log"
    type => "nginx"
    bootstrap_servers => "172.16.20.220:9092,172.16.20.221:9092,172.16.20.222:9092"
    auto_offset_reset => "latest"
  }
}
output {
 if [type] == "api"{
  elasticsearch {
    hosts => ["172.16.20.220:9200","172.16.20.221:9200","172.16.20.222:9200"]
    index => "logstash_api-%{+YYYY.MM.dd}"
    user => "elastic"
    password => "123456"
  }
 }
 if [type] == "operation"{
  elasticsearch {
    hosts => ["172.16.20.220:9200","172.16.20.221:9200","172.16.20.222:9200"]
    index => "logstash_operation-%{+YYYY.MM.dd}"
    user => "elastic"
    password => "123456"
  }
 }
 if [type] == "debugger"{
  elasticsearch {
    hosts => ["172.16.20.220:9200","172.16.20.221:9200","172.16.20.222:9200"]
    index => "logstash_operation-%{+YYYY.MM.dd}"
    user => "elastic"
    password => "123456"
  }
 }
 if [type] == "nginx"{
  elasticsearch {
    hosts => ["172.16.20.220:9200","172.16.20.221:9200","172.16.20.222:9200"]
    index => "logstash_operation-%{+YYYY.MM.dd}"
    user => "elastic"
    password => "123456"
  }
 }
}
    • 启动logstash
    # 切换到bin目录
cd /usr/local/logstash/bin
# 启动命令
nohup ./logstash -f ../config/logstash-kafka.conf &
#查看启动日志
tail -f nohup.out

    四、安装配置Kibana

    • 解压安装文件
    tar -zxvf kibana-8.0.0-linux-x86_64.tar.gz

mv kibana-8.0.0 kibana
    • 修改配置文件
    cd /usr/local/kibana/config
vi kibana.yml
# 修改以下内容
server.port: 5601
server.host: "172.16.20.220"
elasticsearch.hosts: ["http://172.16.20.220:9200","http://172.16.20.221:9200","http://172.16.20.222:9200"]
elasticsearch.username: "kibana_system"
elasticsearch.password: "123456"
    • 启动服务
    cd /usr/local/kibana/bin
# 默认不允许使用root运行，可以添加 --allow-root 参数使用root用户运行，也可以跟Elasticsearch一样新增一个用户组用户
nohup ./kibana --allow-root &

    • 访问http://172.16.20.220:5601/，并使用elastic / 123456登录。

    五、安装Filebeat

      Filebeat用于安装在业务软件运行服务器，收集业务产生的日志，并推送到我们配置的Kafka、Redis、RabbitMQ等消息中间件，或者直接保存到Elasticsearch，下面来讲解如何安装配置：

    1、进入到/usr/local目录，执行解压命令

    tar -zxvf filebeat-8.0.0-linux-x86_64.tar.gz

mv filebeat-8.0.0-linux-x86_64 filebeat

    2、编辑配置filebeat.yml
      配置文件中默认是输出到elasticsearch，这里我们改为kafka，同文件目录下的filebeat.reference.yml文件是所有配置的实例，可以直接将kafka的配置复制到filebeat.yml

    • 配置采集开关和采集路径：
    # filestream is an input for collecting log messages from files.
- type: filestream

  # Change to true to enable this input configuration.
  # enable改为true
  enabled: true

  # Paths that should be crawled and fetched. Glob based paths.
  # 修改微服务日志的实际路径
  paths:

  #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.
  #prospector.scanner.exclude_files: ['.gz$']

  # Optional additional fields. These fields can be freely picked
  # to add additional information to the crawled log files for filtering
  #fields:
  #  level: debug
  #  review: 1
    • Elasticsearch 模板配置
    # ======================= Elasticsearch template setting =======================

setup.template.settings:
  index.number_of_shards: 3
  index.number_of_replicas: 1
  #index.codec: best_compression
  #_source.enabled: false

# 允许自动生成index模板
setup.template.enabled: true
# # 生成index模板时字段配置文件
setup.template.fields: fields.yml
# # 如果存在模块则覆盖
setup.template.overwrite: true
# # 生成index模板的名称
setup.template.name: "api_log" 
# # 生成index模板匹配的index格式 
setup.template.pattern: "api-*" 
#索引生命周期管理ilm功能默认开启，开启的情况下索引名称只能为filebeat-*， 通过setup.ilm.enabled: false进行关闭；
setup.ilm.pattern: "{now/d}"
setup.ilm.enabled: false
    • 开启仪表盘并配置使用Kibana仪表盘：
    # ================================= Dashboards =================================
# These settings control loading the sample dashboards to the Kibana index. Loading
# the dashboards is disabled by default and can be enabled either by setting the
# options here or by using the `setup` command.
setup.dashboards.enabled: true

# The URL from where to download the dashboards archive. By default this URL
# has a value which is computed based on the Beat name and version. For released
# versions, this URL points to the dashboard archive on the artifacts.elastic.co
# website.
#setup.dashboards.url:
# =================================== Kibana ===================================

# Starting with Beats version 6.0.0, the dashboards are loaded via the Kibana API.
# This requires a Kibana endpoint configuration.
setup.kibana:

  # Kibana Host
  # Scheme and port can be left out and will be set to the default (http and 5601)
  # In case you specify and additional path, the scheme is required: http://localhost:5601/path
  # IPv6 addresses should always be defined as: https://[2001:db8::1]:5601
  host: "172.16.20.220:5601"

  # Kibana Space ID
  # ID of the Kibana Space into which the dashboards should be loaded. By default,
  # the Default Space will be used.

    • 执行filebeat启动命令
     ./filebeat -e -c filebeat.yml

    后台启动命令

    nohup ./filebeat -e -c filebeat.yml >/dev/null 2>&1 &

    停止命令

    ps -ef |grep filebeat
kill -9 进程号

    六、测试配置是否正确

    1、测试filebeat是否能够采集log文件并发送到Kafka
    • 在kafka服务器开启消费者，监听api_log主题和operation_log主题
    ./kafka-console-consumer.sh --bootstrap-server 172.16.20.221:9092 --topic api_log

./kafka-console-consumer.sh --bootstrap-server 172.16.20.222:9092 --topic operation_log
    • 手动写入日志文件，按照filebeat配置的采集目录写入
    echo "api log1111" > /data/gitegg/log/gitegg-service-system/api.log

echo "operation log1111" > /data/gitegg/log/gitegg-service-system/operation.log

    • 观察消费者是消费到日志推送内容


      api_log
    operation_log

    2、测试logstash是消费Kafka的日志主题，并将日志内容存入Elasticsearch

    • 手动写入日志文件
    echo "api log8888888888888888888888" > /data/gitegg/log/gitegg-service-system/api.log
echo "operation loggggggggggggggggggg" > /data/gitegg/log/gitegg-service-system/operation.log

    自动新增的两个index，规则是logstash中配置的


    image.png

    数据浏览页可以看到Elasticsearch中存储的日志数据内容，说明我们的配置已经生效。


    image.png

    七、配置Kibana用于日志统计和展示

    • 依次点击左侧菜单Management -> Kibana -> Data Views -> Create data view , 输入logstash_* ,选择@timestamp，再点击Create data view按钮，完成创建。


      image.png
      Kibana

    • 点击日志分析查询菜单Analytics -> Discover，选择logstash_* 进行日志查询
