./elasticsearch

✅ Elasticsearch security features have been automatically configured!
✅ Authentication is enabled and cluster connections are encrypted.ℹ️ Password for the elastic user (reset with bin/elasticsearch-reset-password -u elastic):uQIrmGkSPEDybGehN7Owℹ️ HTTP CA certificate SHA-256 fingerprint:c5ef1227cf14a593d41a24388b4d710dc819c6dd4c3accd0a354b49ac6f28b4fℹ️ Configure Kibana to use this cluster:
• Run Kibana and click the configuration link in the terminal when Kibana starts.
• Copy the following enrollment token and paste it into Kibana in your browser (valid for the next 30 minutes):eyJ2ZXIiOiI4LjEyLjIiLCJhZHIiOlsiMTAuMTAwLjIwOC4yMTo5MjAwIl0sImZnciI6ImM1ZWYxMjI3Y2YxNGE1OTNkNDFhMjQzODhiNGQ3MTBkYzgxOWM2ZGQ0YzNhY2NkMGEzNTRiNDlhYzZmMjhiNGYiLCJrZXkiOiJKelg2Wkk0QmU5cXRJWmF5VzRCbzotOGVyTEUtbVJyT0ZTbzh1UTktQkV3In0ℹ️ Configure other nodes to join this cluster:
• On this node:⁃ Create an enrollment token with bin/elasticsearch-create-enrollment-token -s node.⁃ Uncomment the transport.host setting at the end of config/elasticsearch.yml.⁃ Restart Elasticsearch.
• On other nodes:⁃ Start Elasticsearch with bin/elasticsearch --enrollment-token token, using the enrollment token that you generated.

1.报错max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解决
vim /etc/sysctl.conf
在文件末尾添加以下一行内容vm.max_map_count262144
使文件立即生效sudo sysctl -p2.报错max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]
解决
vim /etc/security/limits.conf
在文件最后面添加下面内容
* soft nofile 65535
* hard nofile 65535
elasticsearch-setup-passwords interactive设置密码时报错
[deployermaster1 bin]$ ./elasticsearch-setup-passwords interactiveFailed to authenticate user elastic against http://xxxxxx:9200/_security/_authenticate?pretty
Possible causes include:* The password for the elastic user has already been changed on this cluster* Your elasticsearch node is running against a different keystoreThis tool used the keystore at /usr/local/ES/elasticsearch-8.12.2/config/elasticsearch.keystoreYou can use the elasticsearch-reset-password CLI tool to reset the password of the elastic userERROR: Failed to verify bootstrap password, with exit code 78解决 删除 .security-7 索引 删除好像没什么用只能通过命令[deployermaster1 bin]$ ./elasticsearch-reset-password -u elastic -i 来重新自定义elastic的用户密码。
3.kibana设置
kibana配置
server.port: 5601 #默认端口
server.host: “0.0.0.0” #对外访问
elasticsearch.hosts: [“http://10.10.10.10:9200”] #elasticsearch地址
i18n.locale: zh-CN #设置中文
后台启动
[rootmaster1 node_modules]# cd /usr/local/ES
[rootmaster1 ES]# ls
elasticsearch-8.12.2 elasticsearch-8.12.2-linux-x86_64.tar.gz elasticsearch-head-master kibana-8.12.2 kibana-8.12.2-linux-x86_64.tar.gz master.zip
[rootmaster1 ES]# cd kibana-8.12.2
nohup bin/kibana 4. 如果出现集群健康值:未连接 请参考 elasticsearch-head-master也需要使用普通用户启动。如果之前使用过root用户启动过elasticsearch-head-master或者elasticsearch需要将elasticsearch-head-master和elasticsearch重新添加普通用户属组和属主。因为使用root启动之后有部分文件的属组合属主变成了root。 先停掉elasticsearch-head-master和elasticsearch然后再赋权
[rootmaster1 ES]# ls
elasticsearch-8.12.2 elasticsearch-8.12.2-linux-x86_64.tar.gz elasticsearch-head-master kibana-8.12.2 kibana-8.12.2-linux-x86_64.tar.gz master.zip
[rootmaster1 ES]# chown deployer:deployer -R elasticsearch-head-master
[rootmaster1 ES]# chown deployer:deployer -R elasticsearch-8.12.2
注意elasticsearch-8.12.2启动后默认开启了密码和ssl设置需要将true改成false 然后重启启动elasticsearch-head-master和elasticsearch
报错
received plaintext http traffic on an https channel, closing connection Netty4HttpChannel{localAddress/xxxxx:9200, remoteAddress/xxxx:57926} 5.ES8默认开启了ssl认证导致无法访问9200端口
elasticsearch.yml配置:xpack.security.enabled:把true改成false 6.kibana设置账号密码
kibana没有自己的登录账号需要使用elasticsearch中添加的账号才行
vim /etc/kibana/kibana.yml
elasticsearch.username: kibana elasticsearch.password: 123456 用户说明 elastic内置超级用户 kibana仅可用于kibana用来连接elasticsearch并与之通信, 不能用于kibana登录logstash_system用于Logstash在Elasticsearch中存储监控信息时使用 kibana安装后验证 # 查看所有节点
GET _cat/nodes# 查看customer索引数据
GET customer/_search
