🌟ES8集群部署实战

停止ES单点服务

1.停止ES服务
[root@elk94 ~]# systemctl stop elasticsearch.service2.查看监听端口
[root@elk94 ~]# ss -ntl | egrep "9200|9300"3.删除数据目录
[root@elk94 ~]# rm -rf /var/lib/elasticsearch/*

拷贝软件包到其他节点

[root@elk94 ~]# scp elasticsearch-8.18.6-amd64.deb  10.0.0.95:~
[root@elk94 ~]# scp elasticsearch-8.18.6-amd64.deb  10.0.0.96:~

其他节点安装ES8软件包

[root@elk95 ~]# dpkg -i elasticsearch-8.18.6-amd64.deb 
[root@elk96 ~]# dpkg -i elasticsearch-8.18.6-amd64.deb

修改ES集群的配置文件

vim /etc/elasticsearch/elasticsearch.yml
cluster.name: es8-cluster
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
http.port: 9200
discovery.seed_hosts: ["10.0.0.94"]
cluster.initial_master_nodes: ["10.0.0.94"]
xpack.security.enabled: true
xpack.security.enrollment.enabled: true
xpack.security.http.ssl:enabled: truekeystore.path: certs/http.p12
xpack.security.transport.ssl:enabled: trueverification_mode: certificatekeystore.path: certs/transport.p12truststore.path: certs/transport.p12

检查配置文件

egrep -v "^#|^$" /etc/elasticsearch/elasticsearch.yml

启动ES服务

[root@elk94 ~]# systemctl enable --now elasticsearch.service 
[root@elk94 ~]# ss -ntl | egrep "9200|9300"

生成token

[root@elk94 ~]# /usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s node
eyJ2ZXIiOiI4LjE0LjAiLCJhZHIiOlsiMTAuMC4wLjk0OjkyMDAiXSwiZmdyIjoiYTRiZWUxODkxMzk3ZjgyNzBiYzMzYmY0MjUzY2JiMjE3OTY3ZjBmYWIxYjgxMzRkN2QzMzEwMWJmY2Y3ZTg4NiIsImtleSI6InprQmlEWmtCMV9CaXpmSVpXaUhlOkdpSFY4YjlUQUZpSU5Kc19qOGk5RWcifQ==

新加入节点使用token注册

被加入节点使用令牌加入，目的是为了拷贝配置文件

[root@elk95 ~]# /usr/share/elasticsearch/bin/elasticsearch-reconfigure-node --enrollment-token eyJ2ZXIiOiI4LjE0LjAiLCJhZHIiOlsiMTAuMC4wLjk0OjkyMDAiXSwiZmdyIjoiYTRiZWUxODkxMzk3ZjgyNzBiYzMzYmY0MjUzY2JiMjE3OTY3ZjBmYWIxYjgxMzRkN2QzMzEwMWJmY2Y3ZTg4NiIsImtleSI6InprQmlEWmtCMV9CaXpmSVpXaUhlOkdpSFY4YjlUQUZpSU5Kc19qOGk5RWcifQ==[root@elk96 ~]# /usr/share/elasticsearch/bin/elasticsearch-reconfigure-node --enrollment-token eyJ2ZXIiOiI4LjE0LjAiLCJhZHIiOlsiMTAuMC4wLjk0OjkyMDAiXSwiZmdyIjoiYTRiZWUxODkxMzk3ZjgyNzBiYzMzYmY0MjUzY2JiMjE3OTY3ZjBmYWIxYjgxMzRkN2QzMzEwMWJmY2Y3ZTg4NiIsImtleSI6InprQmlEWmtCMV9CaXpmSVpXaUhlOkdpSFY4YjlUQUZpSU5Kc19qOGk5RWcifQ==

经过测试发现集群并没有加入成功

[root@elk96 ~]# curl -k https://10.0.0.94:9200/_cat/nodes -u "elastic:CkugKRWSr6sn01KfDr1o"

手动修改ES集群配置文件

[root@elk94 ~]# vim /etc/elasticsearch/elasticsearch.yml 
cluster.name: oldboyedu-linux99-es8-cluster
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
http.port: 9200
discovery.seed_hosts: ["10.0.0.94","10.0.0.95","10.0.0.96"]
cluster.initial_master_nodes: ["10.0.0.94"]
xpack.security.enabled: true
xpack.security.enrollment.enabled: true
xpack.security.http.ssl:enabled: truekeystore.path: certs/http.p12
xpack.security.transport.ssl:enabled: trueverification_mode: certificatekeystore.path: certs/transport.p12truststore.path: certs/transport.p12

同步配置文件到所有节点

[root@elk94 ~]# scp /etc/elasticsearch/elasticsearch.yml  10.0.0.95:/etc/elasticsearch/
[root@elk94 ~]# scp /etc/elasticsearch/elasticsearch.yml  10.0.0.96:/etc/elasticsearch/

重启ES集群

[root@elk94 ~]# systemctl restart elasticsearch.service 
[root@elk95 ~]# systemctl restart elasticsearch.service 
[root@elk96 ~]# systemctl restart elasticsearch.service

再次测试验证

curl -k https://10.0.0.94:9200/_cat/nodes -u "elastic:CkugKRWSr6sn01KfDr1o"

🌟ES8重置管理员elastic密码

重置密码

/usr/share/elasticsearch/bin/elasticsearch-reset-password -u elastic
This tool will reset the password of the [elastic] user to an autogenerated value.
The password will be printed in the console.
Please confirm that you would like to continue [y/N]y  # 手动输入字母'y'Password for the [elastic] user successfully reset.
New value: AQmNtJ2v=grGHGB89e2c  # 这是新密码

用旧密码将无法访问

curl -k https://10.0.0.94:9200/_cat/nodes?v -u "elastic:iVzoK-8a1eOF+O87lHcw"

使用新密码是可以正常访问的

curl -k https://10.0.0.94:9200/_cat/nodes?v -u "elastic:AQmNtJ2v=grGHGB89e2c"

🌟filebeat对接ES8实战

下载filebeat

[root@elk95 ~]# wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-8.18.6-amd64.deb

安装filebeat

[root@elk95 ~]# dpkg -i filebeat-8.18.6-amd64.deb

创建api-key

AwuFDZkBg8OuYXYCzZPM:O1P8XATTDJzZro6Fj0gORA

编写filebeat的配置文件

[root@elk95 ~]# vim /etc/filebeat/01-tcp-to-es.yaml
filebeat.inputs:
- type: tcphost: "0.0.0.0:9000"output.elasticsearch:hosts:- https://10.0.0.94:9200- https://10.0.0.95:9200- https://10.0.0.96:9200api_key: "AwuFDZkBg8OuYXYCzZPM:O1P8XATTDJzZro6Fj0gORA"index: es8-apikey-001# 跳过客户端证书校验。ssl.verification_mode: nonesetup.ilm.enabled: false

启动filebeat实例

[root@elk95 ~]# filebeat -e -c /etc/filebeat/01-tcp-to-es.yaml

发送测试数据

[root@elk94 ~]# echo xixi | nc 10.0.0.95 9000

kibana查看数据

🌟logstash对接ES8集群

下载logstash

官网下载：https://artifacts.elastic.co/downloads/logstash/logstash-8.18.6-amd64.deb

[root@elk95 ~]# wget https://artifacts.elastic.co/downloads/logstash/logstash-8.18.6-amd64.deb

安装logstash

创建符号链接

[root@elk95 ~]# ln -svf /usr/share/logstash/bin/logstash /usr/local/bin/

创建api-key

建议基于图形化创建，后期可以考虑使用API创建

AwuFDZkBg8OuYXYCzZPM:O1P8XATTDJzZro6Fj0gORA

编写Logstash配置文件

cat > /etc/logstash/conf.d/01-tcp-to-es.yaml <<EOF
input { tcp {port => 8888}
}  output { if [type] == "dba" {elasticsearch {hosts => ["https://10.0.0.94:9200","https://10.0.0.95:9200","https://10.0.0.96:9200"]index => "zhu-es8-apikey-002"api_key => "AwuFDZkBg8OuYXYCzZPM:O1P8XATTDJzZro6Fj0gORA"ssl => truessl_certificate_verification => false}
}
EOF

启动Logstash

[root@elk96 ~]# logstash -f /etc/logstash/conf.d/01-tcp-to-es.yaml

发送测试数据

[root@elk94 ~]# echo haha | nc 10.0.0.96 8888

🌟ES8和ES7对比

1️⃣ES8默认启用了https，支持认证等功能;

2️⃣ES8新增’elasticsearch-reset-password’脚本，对于elastic用户重置密码更加简单;

3️⃣ES8新增’elasticsearch-create-enrollment-token’脚本，可以为组件创建token信息，比如kibana，node组件；

4️⃣ES8新增kibana新增’kibana-verification-code’用于生成校验码。

5️⃣kibana支持更多的语言：English (default) “en”, Chinese “zh-CN”, Japanese “ja-JP”, French “fr-FR”

6️⃣kibana的webUI更加丰富，支持AI助手，手动创建索引等功能;

7️⃣kibana不用创建索引模式就可以直接查看数据，系统会生成一个临时的视图以供查看;

8️⃣ES8集群部署时，需要借助’elasticsearch-reconfigure-node’脚本来加入已存在的集群，默认就是单master节点的配置;

🌟ELFK架构采集系统日志

创建api-key

创建zhu-es8-apikey-syslog索引的apikey

sys: 2AsqDpkBg8OuYXYCH6ER:90EhDgoopSqrU_effytCxQ

创建zhu-es8-apikey-auth索引的apikey

auth: 2gssDpkBg8OuYXYCeaGs:GMdZw1qEINar0NUnuU6BpQ

input { beats {port => 6666type => auth}beats {port => 7777type => syslog}
}  output { if [type] == "auth" {elasticsearch {hosts => ["https://10.0.0.94:9200","https://10.0.0.95:9200","https://10.0.0.96:9200"]index => "zhu-es8-apikey-auth"api_key => "2gssDpkBg8OuYXYCeaGs:GMdZw1qEINar0NUnuU6BpQ"ssl => truessl_certificate_verification => false}} else {elasticsearch {hosts => ["https://10.0.0.94:9200","https://10.0.0.95:9200","https://10.0.0.96:9200"]index => "zhu-es8-apikey-syslog"api_key => "2AsqDpkBg8OuYXYCH6ER:90EhDgoopSqrU_effytCxQ"ssl => truessl_certificate_verification => false}}
}
EOF

启动logstash

logstash -r -f /etc/logstash/conf.d/02-beats-to-es.yaml

编写filebeat配置文件采集auth日志

cat > /etc/filebeat/02-auth-to-logstash.yaml <<'EOF'

filebeat -e -c /etc/filebeat/02-auth-to-logstash.yaml

创建角色

创建用户关联角色

登录用户

使用xixi用户登录

使用haha用户登录

🌟zookeeper单点部署

什么是zookeeper

ZooKeeper是一个集中式服务，用于维护配置信息、命名、提供分布式同步和提供组服务

所有这些类型的服务都以某种形式被分布式应用程序使用

主要的应用场景： Kafka，HDFS HA，YARN HA，HBase，Solr，…

官网地址: https://zookeeper.apache.org/

下载zookeeper

官方网站下载：https://dlcdn.apache.org/zookeeper/zookeeper-3.8.4/apache-zookeeper-3.8.4-bin.tar.gz

[root@elk91 ~]# wget https://dlcdn.apache.org/zookeeper/zookeeper-3.8.4/apache-zookeeper-3.8.4-bin.tar.gz

解压软件包

[root@elk91 ~]# tar xf apache-zookeeper-3.8.4-bin.tar.gz -C /usr/local/

配置环境变量

1.修改环境变量子配置文件
vim /etc/profile.d/zk.sh
#!/bin/bash
export ZK_HOME=/usr/local/apache-zookeeper-3.8.4-bin
export JAVA_HOME=/usr/share/elasticsearch/jdk
export PATH=$PATH:${ZK_HOME}/bin:${JAVA_HOME}/bin2.加载环境变量
source /etc/profile.d/zk.sh3.检查
java --version

准备配置文件

[root@elk91 ~]# cp /usr/local/apache-zookeeper-3.8.4-bin/conf/zoo{_sample,}.cfg

启动zookeeper服务

zkServer.sh start

查看zookeeper状态

zkServer.sh status

登录测试

zkCli.sh -server 10.0.0.91:2181

🌟zookeeper的基本使用

创建zookeeper node

[zk: 10.0.0.91:2181(CONNECTED) 1] create /haha ha
Created /haha

查看zookeeper node列表

[zk: 10.0.0.91:2181(CONNECTED) 9] ls /
[haha, zookeeper]

查看zookeeper node数据

[zk: 10.0.0.91:2181(CONNECTED) 4] get /haha
haha

修改zookeeper node数据

[zk: 10.0.0.91:2181(CONNECTED) 3] set /haha haha
[zk: 10.0.0.91:2181(CONNECTED) 4] get /haha
haha

删除zookeeper node

[zk: 10.0.0.91:2181(CONNECTED) 5] delete
delete      deleteall   
[zk: 10.0.0.91:2181(CONNECTED) 5] delete /haha
[zk: 10.0.0.91:2181(CONNECTED) 6] ls /
[zookeeper]

delete只能删除空目录，deleteall可以递归删除目录

创建层级的zookeeper node

[zk: 10.0.0.91:2181(CONNECTED) 7] create /haha
Created /haha
[zk: 10.0.0.91:2181(CONNECTED) 8] set /haha haha
[zk: 10.0.0.91:2181(CONNECTED) 9] ls /
[haha, zookeeper]
[zk: 10.0.0.91:2181(CONNECTED) 10] create /haha/xixi xixi
Created /haha/xixi

🌟zookeeper的集群部署

集群模式节点数量选择

参考链接: https://zookeeper.apache.org/doc/current/zookeeperOver.html

停止单点服务

zkServer.sh stop

修改zookeeper的配置文件

vim /usr/local/apache-zookeeper-3.8.4-bin/conf/zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/lib/zookeeper
clientPort=2181
server.11=10.0.0.91:2888:3888
server.22=10.0.0.92:2888:3888
server.33=10.0.0.93:2888:3888

将程序和环境变量文件同步到集群的其他节点

scp -r /usr/local/apache-zookeeper-3.8.4-bin/ 10.0.0.92:/usr/local
scp -r /usr/local/apache-zookeeper-3.8.4-bin/ 10.0.0.93:/usr/local
scp /etc/profile.d/zk.sh 10.0.0.92:/etc/profile.d/
scp /etc/profile.d/zk.sh 10.0.0.93:/etc/profile.d/

所有节点准备数据目录

[root@elk91 ~]# mkdir /var/lib/zookeeper && echo 11 > /var/lib/zookeeper/myid
[root@elk92 ~]# mkdir /var/lib/zookeeper && echo 22 > /var/lib/zookeeper/myid
[root@elk93 ~]# mkdir /var/lib/zookeeper && echo 33 > /var/lib/zookeeper/myid

检查集群的状态

zkServer.sh status

客户端链接测试

zkCli.sh -server 10.0.0.91:2181,10.0.0.92:2181,10.0.0.93:2181

验证zookeeper集群高可用

开启两个终端指向不同的节点分别写入数据测试

[root@elk92 ~]# zkCli.sh -server 10.0.0.92:2181
[root@elk93 ~]# zkCli.sh -server 10.0.0.93:2181

停止leader节点观察是否可用

[root@elk91 ~]# zkCli.sh -server 10.0.0.91:2181,10.0.0.92:2181,10.0.0.93:2181

停止服务观察终端是否可用

[root@elk93 ~]# zkServer.sh stop

测试验证故障容忍节点数量

[root@elk92 ~]# zkServer.sh stop
[root@elk93 ~]# zkServer.sh stop

zookeeper集群要保证半数以上存活机制

一个集群如果想要容忍N台故障，则要求有2N+1台服务器

举例子:

如果集群容忍挂掉1个节点，则至少要准备2*1 + 1 = 3台服务器

如果集群容忍挂掉2个节点，则至少要准备2*2 + 1 = 5台服务器

🌟zookeeper的leader选举流程

1️⃣启动集群是默认都认为自己是leader，进行leader选举

2️⃣选举时各节点要暴露出自己的： myid，zxid

3️⃣先比较zxid事务ID，越大就优先被选举为leader

4️⃣如果zxid比不出来，则比较myid，myid越大则优先成为leader

5️⃣当zookeeper集群半数以上节点参与选举完成，则leader就确认下来了

🌟zookeeper的watch机制及node类型

watch监听子节点是否变化，节点数据是否变化

node类型：临时和永久

终端1监听事件

[zk: 10.0.0.93:2181(CONNECTED) 1] ls -w /haha

终端2触发事件

[zk: 10.0.0.92:2181(CONNECTED) 0] create /haha/haha
Created /haha/haha
[zk: 10.0.0.92:2181(CONNECTED) 1]

观察终端1出现结果

[zk: 10.0.0.93:2181(CONNECTED) 0] ls /haha
[heihei, xixi]
[zk: 10.0.0.93:2181(CONNECTED) 1] ls -w /haha
[heihei, xixi]
[zk: 10.0.0.93:2181(CONNECTED) 2] 
WATCHER::WatchedEvent state:SyncConnected type:NodeChildrenChanged path:/haha

类似watch还支持监控数据变化

[zk: 10.0.0.93:2181(CONNECTED) 2] get -w /haha/xixi
null
[zk: 10.0.0.93:2181(CONNECTED) 3] 
WATCHER::WatchedEvent state:SyncConnected type:NodeDataChanged path:/haha/xixi

🌟zookeeper的类型

临时的zookeeper node

当链接断开，zookeeper node在一定时间范围(30s)内自动删除

永久的zookeeper node

当链接断开后，zookeeper node数据并不丢失

默认情况下，我们创建的 都是永久的zookeeper node

[zk: 10.0.0.93:2181(CONNECTED) 5] stat /linshi
cZxid = 0x400000005
ctime = Wed Sep 03 08:57:38 UTC 2025
mZxid = 0x400000005
mtime = Wed Sep 03 08:57:38 UTC 2025
pZxid = 0x400000005
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x21000060bad10000
dataLength = 0
numChildren = 0
[zk: 10.0.0.93:2181(CONNECTED) 6] create /yongjiu
Created /yongjiu
[zk: 10.0.0.93:2181(CONNECTED) 7] stat /yongjiu
cZxid = 0x400000006
ctime = Wed Sep 03 09:02:52 UTC 2025
mZxid = 0x400000006
mtime = Wed Sep 03 09:02:52 UTC 2025
pZxid = 0x400000006
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 0
numChildren = 0
[zk: 10.0.0.93:2181(CONNECTED) 8]

当前连接的session 会话ID。当当前会话断开30s(negotiated timeout)后会自动删除

当前会话ID为：0x21000060bad10000

断开会话重新连接，临时的node自动删除
