kubernetes部署ELK Stack

文章目录

提供者：MappleZF

版本：1.0.0

一、部署ElasticSearch

1.1 下载

官网:https://www.elastic.co/cn/

官网下载地址：https://www.elastic.co/cn/downloads/elasticsearch

[root@k8smaster01:/opt/src]# wget -c https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.9.0-linux-x86_64.tar.gz
[root@k8smaster01:/opt/src]# wget -c https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.8.12.tar.gz

1.2 安装JDK11

注：ElasticSearch 7.X 版本需要JDK11支持

jdk下载地址请官方下载

[root@k8smaster02.host.com:/opt/src]# tar -xf jdk-11.0.8_linux-x64_bin.tar -C /usr/local/
[root@k8smaster02.host.com:/opt/src]# cd /usr/local/  && cd jdk-11.0.8/  && ls
bin  conf  include  jmods  legal  lib  README.html  release

1.3 安装Elasticsearch

[root@k8smaster02.host.com:/opt/src]# tar -xf elasticsearch-7.9.0-linux-x86_64.tar.gz -C /data/ 
[root@k8smaster02.host.com:/opt/src]# cd /data/  && mv elasticsearch-7.9.0 elasticsearch
[root@k8smaster02.host.com:/data]# mkdir -p /data/elasticsearch/{data,logs}

由于我们日常的代码开发都是使用的JDK1.8，所以这里不会把JAVA_HOME配置成JDK11，我们只需更改Elasticsearch的启动文件，使它指向我们下载的JDK11.

1.4 配置Elasticsearch

1.4.1 修改elasticsearch/bin/elasticsearch

[root@k8smaster02.host.com:/data/elasticsearch/bin]# vim elasticsearch
添加如下内容：
#!/bin/bash

# CONTROLLING STARTUP:
#
# This script relies on a few environment variables to determine startup
# behavior, those variables are:
#
#   ES_PATH_CONF -- Path to config directory
#   ES_JAVA_OPTS -- External Java Opts on top of the defaults set
#
# Optionally, exact memory values can be set using the `ES_JAVA_OPTS`. Example
# values are "512m", and "10g".
#
#   ES_JAVA_OPTS="-Xms8g -Xmx8g" ./bin/elasticsearch
#配置自己的jdk11
export JAVA_HOME=/usr/local/jdk-11.0.8
export PATH=$JAVA_HOME/bin:$PATH

#添加jdk判断
if [ -x "$JAVA_HOME/bin/java" ]; then
        JAVA="/usr/local/jdk-11.0.8/bin/java"
else
        JAVA=`which java`
fi

source "`dirname "$0"`"/elasticsearch-env
.........(省略号)........

1.4.2 修改elasticsearch/config/elasticsearch.yml

root@k8smaster02.host.com:/data/elasticsearch/config]# vim elasticsearch.yml
修改如下内容：
cluster.name: es.lowan.com
node.name: k8smaster02.host.com
path.data: /data/elasticsearch/data
path.logs: /data/elasticsearch/logs
bootstrap.memory_lock: true
network.host: 192.168.13.102
http.port: 9200


注意：如果部署的是单节点的话。还需要修改下列内容
不然会报如下错误：[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
ERROR: Elasticsearch did not exit normally - check the logs at /data/elasticsearch/logs/es.lowan.com.log
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1", "host2"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
cluster.initial_master_nodes: ["k8smaster02.host.com"]
#cluster.initial_master_nodes: ["node-1", "node-2"]
#

1.4.3 优化jam.options

[root@k8smaster02.host.com:/data/elasticsearch/config]# vim jvm.options
修改如下内容：
# 内存足够的话，可以考虑最大给到32G内存

-Xms12g
-Xmx12g

## GC configuration
## 原有的注释了，添加了G1回收器,原因是经典款11支持的垃圾回收器是-XX:+UseG1GC
#8-13:-XX:+UseConcMarkSweepGC
#8-13:-XX:CMSInitiatingOccupancyFraction=75
#8-13:-XX:+UseCMSInitiatingOccupancyOnly
-XX:+UseG1GC
-XX:CMSInitiatingOccupancyFraction=75
-XX:+UseCMSInitiatingOccupancyOnly

1.4.4 创建普通用户

注：ES使用root用户是无法启动的

[root@k8smaster02.host.com:/data/elasticsearch]# useradd -s /bin/bash -M elasticsearch
[root@k8smaster02.host.com:/data/elasticsearch]# chown -R elasticsearch:elasticsearch /data/elasticsearch
[root@k8smaster02.host.com:/data/elasticsearch]# id elasticsearch
uid=1001(elasticsearch) gid=1001(elasticsearch) 组=1001(elasticsearch)

1.4.5 修改文件描述符

[root@k8smaster02.host.com:/etc/security]# vim /etc/security/limits.d/elasticsearch.conf
elasticsearch soft nofile 1048576
elasticsearch soft fsize unlimited
elasticsearch hard memlock unlimited
elasticsearch soft memlock unlimited
~

1.4.6 优化内核

[root@k8smaster02.host.com:/etc/security]# sysctl -w vm.max_map_count=262144
vm.max_map_count = 262144
[root@k8smaster02.host.com:/etc/security]# echo "vm.max_map_count=262144" >> /etc/sysctl.conf
[root@k8smaster02.host.com:/etc/security]# sysctl -p
vm.max_map_count = 262144

或者用脚本
if [ `grep 'vm.max_map_count'  /etc/sysctl.conf|wc -l` -eq 0 ];then
   echo 'vm.max_map_count=262144' >>/etc/sysctl.conf
fi

1.5 启动elasticsearch

[root@k8smaster02.host.com:/data/elasticsearch/bin]# su -c "/data/elasticsearch/bin/elasticsearch -d" elasticsearch
[root@k8smaster02.host.com:/data/elasticsearch/bin]# ps -ef | grep elasticsearch 
elastic+  244947       1 71 22:04 ?        00:01:24 /usr/local/jdk-11.0.8/bin/java -Xshare:auto -Des.networkaddress.cache.ttl=60 -Des.networkaddress.cache.negative.ttl=10 -XX:+AlwaysPreTouch -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 -Dio.netty.allocator.numDirectArenas=0 -Dlog4j.shutdownHookEnabled=false -Dlog4j2.disable.jmx=true -Djava.locale.providers=SPI,COMPAT -Xms12g -Xmx12g -XX:+UseG1GC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -Djava.io.tmpdir=/tmp/elasticsearch-3665753017343694820 -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=data -XX:ErrorFile=logs/hs_err_pid%p.log -Xlog:gc*,gc+age=trace,safepoint:file=logs/gc.log:utctime,pid,tags:filecount=32,filesize=64m -XX:MaxDirectMemorySize=6442450944 -Des.path.home=/data/elasticsearch -Des.path.conf=/data/elasticsearch/config -Des.distribution.flavor=default -Des.distribution.type=tar -Des.bundled_jdk=true -cp /data/elasticsearch/lib/* org.elasticsearch.bootstrap.Elasticsearch -d
elastic+  245137  244947  0 22:04 ?        00:00:00 /data/elasticsearch/modules/x-pack-ml/platform/linux-x86_64/bin/controller
root      247347  137060  0 22:06 pts/2    00:00:00 grep --color=auto elasticsearch

[root@k8smaster02.host.com:/data/elasticsearch/bin]# netstat -luntp | grep 9200
tcp6       0      0 192.168.13.102:9200     :::*                    LISTEN      244947/java

1.6 调整elasticsearch日志模版

[root@k8smaster02.host.com:/data/elasticsearch/bin]# 
注： 由于是单机单副本，所以需要如下操作，假如是三机集群就可以不用一下操作
curl -H "Content-Type:application/json" -XPUT http://192.168.13.102:9200/_template/k8s -d '{
	"template": "k8s*",
	"index_patterns": ["k8s*"],
	"settings": {
		"number_of_shards": 5,
		"number_of_replicas": 0
	}
}'

1.7 删除ELK索引脚本

#还未测试
#!/bin/bash
# 保留7天的日志索引
DATE=`date -d "7 days ago" +%Y.%m.%d`
# 索引的名字
LOG_NAMES=(es-nacos-server es-eureka-server)
# 遍历所有时间段的索引，并删除大于7天的索引文件，打印删除成功
for LOG_NAME in ${LOG_NAMES[*]}
do
  FILE_NAME=${LOG_NAME}-${DATE}
  curl -XDELETE  http://192.168.56.30:9200/${FILE_NAME}
  echo "${FILE_NAME} delete success"
done

二、制作filebeat底包

官方地址https://www.elastic.co/cn/downloads/past-releases/filebeat-7-9-0

2.1 制作Dockerfile

[root@k8smaster01.host.com:/data/Dockerfile/filebeat]# vim Dockerfile
FROM debian:jessie

ENV FILEBEAT_VERSION=7.9.0 \
    FILEBEAT_SHA512=a069cc0906ff95d1c42118d501edc81d8af10d77124e5b38d209201d49e6649e4e2130a270885131abda214fee72c60f0d0174ef9ba92617ecc5b2554bc2fc35

COPY filebeat-7.9.0-linux-x86_64.tar.gz /opt/
RUN set -x && \
  apt-get update && \
  mv /opt/filebeat-7.9.0-linux-x86_64.tar.gz /opt/filebeat.tar.gz && \
  cd /opt && \
  echo "${FILEBEAT_SHA512}  filebeat.tar.gz" | sha512sum -c - && \
  tar xzvf filebeat.tar.gz && \
  cd filebeat-* && \
  cp filebeat /bin && \
  cd /opt && \
  rm -rf filebeat* && \
  apt-get autoremove -y && \
  apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

COPY docker-entrypoint.sh /
ENTRYPOINT ["/docker-entrypoint.sh"]

2.2 制作docker-entrypoint.sh

[root@k8smaster01.host.com:/data/Dockerfile/filebeat]# vim docker-entrypoint.sh

#!/bin/bash

ENV=${ENV:-"test"}
PROJ_NAME=${PROJ_NAME:-"no-define"}

  max_message_bytes: 10485760
EOF

set -xe

#If user don't provide any command
# Run filebeat
if [[ "$1" == "" ]]; then
        exec filebeat -c /etc/filebeat.yaml
else
        # Else allow the user to run arbitraritu commandes like bash
        exec "$@"
fi

#增加执行权限
[root@k8smaster01.host.com:/data/Dockerfile/filebeat]# chmod +x docker-entrypoint.sh

2.3 构建filebeat镜像

[root@k8smaster01.host.com:/data/Dockerfile/filebeat]# docker build -t harbor.iot.com/base/filebeat:7.9.0 .

2.4 filebeat接入p003-web

2.4.1 修改p003-web的deployment

[root@k8smaster01.host.com:/data/yaml/p003-web]# vim dp.yaml 

apiVersion: apps/v1
kind: Deployment
metadata:
  name: p003-web
  labels:
    app: p003-web
spec:
  replicas: 1
  selector:
    matchLabels:
      app: p003-web
  template:
    metadata:
      labels:
        app: p003-web
    spec:
      containers:
      - name: p003-web
        image: harbor.iot.com/p003/alpine_p003_web:V1.1.17
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 20300
          protocol: TCP
          name: tcp20300
        command:
        - sh
        - -c
        - "exec nginx -g 'daemon off;'"
        volumeMounts:
        - name: logm
          mountPath: "/opt/P003/log"
        - name: p003-web-config-volume
          mountPath: "/etc/nginx/conf.d"
        - name: p003-mqtt-config-volume
          mountPath: "/opt/P003/static-config"
        resources:
          limits:
            cpu: 1000m
            memory: 2000Mi
          requests:
            cpu: 200m
            memory: 350Mi
      - name: filebeat
        image: harbor.iot.com/base/filebeat:7.9.0
        imagePullPolicy: IfNotPresent
        env:
        - name: ENV
          value: test
        - name: PROJ_NAME
          value: p003-web-log
        volumeMounts:
        - mountPath: /logm
          name: logm
      volumes:
      - name: logm
        emptyDir: {}
      - name: p003-web-config-volume
        configMap:
          name: p003-web-nginx-conf
      - name: p003-mqtt-config-volume
        configMap:
          name: p003-web-mqtt-conf
      imagePullSecrets:
      - name: harbor
      terminationGracePeriodSeconds: 30
      securityContext:
        runAsUser: 0
      schedulerName: default-scheduler
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxSurge: 1  # 一次可以添加多少个Pod.
      maxUnavailable: 0  # 滚动更新期间最大多少个Pod不可用.
      # maxUnavailable设置为0可以完全确保在滚动更新期间服务不受影响，还可以使用百分比的值来进行设置。
  revisionHistoryLimit: 5
  progressDeadlineSeconds: 600

2.4.2 运行p003-web和filebeat

[root@k8smaster01.host.com:/data/yaml/p003-web]# kubectl apply -f dp.yaml 
deployment.apps/p003-web created

三、部署logstash

3.1准备镜像

docker pull logstash:7.9.0
docker tag docker.io/library/logstash:7.9.0 harbor.iot.com/base/logstash:7.9.0
docker push harbor.iot.com/base/logstash:7.9.0

3.2 创建namespace

[root@k8smaster01.host.com:/data/yaml/logstash]# vim namespace-es.yaml
apiVersion: v1
kind: Namespace
metadata:
  name: es

3.3 创建logstash的configmap

[root@k8smaster01.host.com:/data/yaml/logstash]# vim configmap-logstash-conf.yaml

kind: ConfigMap
apiVersion: v1
metadata:
  name: logstash-conf
  namespace: es
data:
  logstash.conf: |
    input {
      kafka {
         bootstrap_servers => ["kafka0.lowan.com:9092,kafka1.lowan.com:9092,kafka2.lowan.com:9092"]
         client_id => "test"
         group_id => "k8s_test"
         auto_offset_reset => "latest"
         consumer_threads => 4
         decorate_events => true
         topics_pattern => ["k8s-fb-test-.*"]
         }
       }
    filter {
      json { 
        source => "message"      
         }   
      } 

    output {
      elasticsearch {
        hosts => ["192.168.13.102:9200"]
        index => "k8s-test-%{+YYYY.MM.DD}"
         }
      }

3.4 创建logstash的service

[root@k8smaster01.host.com:/data/yaml/logstash]# vim svc-logstash.yaml
kind: Service
apiVersion: v1
metadata:
  labels:
    elastic-app: logstash
  name: logstash-service
  namespace: es
spec:
  ports:
  - port: 8080
    targetPort: 8080
  selector:
    elastic-app: logstash
 # type: NodePort  我们使用Ingressroute，因此不用nodeport，如测试要使用再开启

3.5 创建logstash的deployment

[root@k8smaster01.host.com:/data/yaml/logstash]# vim deployment-logstash.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    elastic-app: logstash
  name: logstash
  namespace: es
spec:
  replicas: 1
  revisionHistoryLimit: 10
  selector:
    matchLabels:
      elastic-app: logstash
  template:
    metadata:
      labels:
        elastic-app: logstash
    spec:
      containers:
      - name: logstash
        image: harbor.iot.com/base/logstash:7.9.0
        volumeMounts:
        - mountPath: /usr/share/logstash/pipeline/logstash.conf
          subPath: logstash.conf
          name: logstash-conf
        ports:
        - containerPort: 8080
          protocol: TCP
        env:
        - name: "XPACK_MONITORING_ELASTICSEARCH_URL"
          value: "http://192.168.13.102:9200"
        securityContext:
          privileged: true
        resources:
          limits:
            cpu: 1000m
            memory: 4000Mi
          requests:
            cpu: 200m
            memory: 350Mi
      volumes:
      - name: logstash-conf
        configMap:
          name: logstash-conf
      tolerations:
      - key: node-role.kubernetes.io/master
        effect: NoSchedule

3.6 应用资源配置清单

[root@k8smaster01.host.com:/data/yaml/logstash]# kubectl apply -f namespace-es.yaml 
[root@k8smaster01.host.com:/data/yaml/logstash]# kubectl apply -f svc-logstash.yaml 
[root@k8smaster01.host.com:/data/yaml/logstash]# kubectl apply -f configmap-logstash-conf.yaml 
[root@k8smaster01.host.com:/data/yaml/logstash]# kubectl apply -f deployment-logstash.yaml

3.7 检查日志

curl http://192.168.13.102:9200/_cat/indices?v

[root@k8smaster02.host.com:/opt/zookeeper/logs]# curl http://192.168.13.102:9200/_cat/indices?v

四、部署kibana

4.1 准备镜像

docker pull kibana:7.9.0
docker tag docker.io/library/kibana:7.9.0 harbor.iot.com/base/kibana:7.9.0
docker push harbor.iot.com/base/kibana:7.9.0

4.2 创建kibana的service

[root@k8smaster01.host.com:/data/yaml/kibana]# vim svc-kibana.yaml
kind: Service
apiVersion: v1
metadata:
  labels:
    elastic-app: kibana
  name: kibana-service
  namespace: es
spec:
  ports:
  - protocol: TCP
    port: 5601
    targetPort: 5601
  selector:
    elastic-app: kibana

4.3 创建kibana的configMap

[root@k8smaster01.host.com:/data/yaml/kibana]# vim configmap-kibana.yaml 
apiVersion: v1
kind: ConfigMap
metadata:
  name: kibana-config
  namespace: es
data:
  kibana.yml: |
    server.name: kibana
    server.host: "0"
    elasticsearch.hosts: [ "http://es.lowan.com:9200" ]
    monitoring.ui.container.elasticsearch.enabled: true

4.4 创建kibana的deployment

[root@k8smaster01.host.com:/data/yaml/kibana]# vim deployment-kibana.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    elastic-app: kibana
  name: kibana
  namespace: es
spec:
  replicas: 1
  revisionHistoryLimit: 10
  selector:
    matchLabels:
      elastic-app: kibana
  template:
    metadata:
      labels:
        elastic-app: kibana
    spec:
      containers:
      - name: kibana
        image: harbor.iot.com/base/kibana:7.9.0
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 5601
          protocol: TCP
        env:
        - name: "elasticsearch.hosts"
          value: "http://es.lowan.com:9200"
        resources:
          limits:
            cpu: 2000m
            memory: 4000Mi
          requests:
            cpu: 200m
            memory: 350Mi
        volumeMounts:
        - name: kibana-config-v
          mountPath: /usr/share/kibana/config/kibana.yml
          subPath: kibana.yml
      volumes:
      - name: kibana-config-v
        configMap:
          name: kibana-config
          items:
          - key: kibana.yml
            path: kibana.yml
      tolerations:
      - key: node-role.kubernetes.io/master
        effect: NoSchedule
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxUnavailable: 1
      maxSurge: 1
  revisionHistoryLimit: 7
  progressDeadlineSeconds: 600

4.5 创建kibana的ingressroute

[root@k8smaster01.host.com:/data/yaml/kibana]# vim ingressroute-kibana.yaml
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  labels:
    app: kibana
  name: kibana-ingress
  namespace: es
  annotations:
    traefik.ingress.kubernetes.io/router.entrypoints: web
    kubernetes.io/ingress.class: "traefik"
spec:
  entryPoints:
  - web
  routes:
  - match: Host(`kibana.lowan.com`) && PathPrefix(`/`)
    kind: Rule
    services:
    - name: kibana-service
      port: 5601

4.6 配置DNS域名解析

[root@lb03.host.com:/var/named]# vim lowan.com.zone
$ORIGIN lowan.com.
$TTL 600        ; 10 minutes
@       IN SOA  dns.lowan.com.   dnsadmin.lowan.com. (
                                        2020101011        ; serial
                                        10800             ; refresh (3 hours)
                                        900               ; retry (15 minutes)
