此處簡單記錄一下,elasticsearch8
和kibana8
在Centos7
下的單機安裝步驟。
不同版本的es
對jdk
和作業系統
的要求不等,我們選擇合適的版本,可以通過如下 https://www.elastic.co/cn/support/matrix進行確認。

需要為es
單獨建立一個使用者,使用root
賬戶啟動es
會報錯。
[root@appbasic ~]# useradd es
[root@appbasic ~]# passwd es
[root@appbasic es]# tar -zxf elasticsearch-8.4.3-linux-aarch64.tar.gz
[root@appbasic es]# chown es -R elasticsearch-8.4.3
[root@appbasic es]# su - es

[es@appbasic ~]$ cd /usr/local/es/elasticsearch-8.4.3
[es@appbasic elasticsearch-8.4.3]$ mkdir datas
[es@appbasic elasticsearch-8.4.3]$
vim config/elasticsearch.yml
# 叢集名
cluster.name: es-cluster
# 節點名
node.name: es-node01
# 資料目錄

# 紀錄檔目錄

# es繫結到的地址

# es啟動後前端存取的埠
http.port: 9200
http.cors.enabled: true
http.cors.allow-origin: "*"
vim config/jvm.options
可以根據實際情況 修改一下 -Xms 和 -Xmx
等引數
ulimit -n
檢視當前使用者可開啟的檔案數vim /etc/security/limits.conf
es soft nofile 65536
es hard nofile 65536

/etc/fstab
註釋掉所有行中存在 swap
的行。
# /dev/mapper/cl_fedora-swap none swap defaults 0 0
參考連結: https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration-memory.html
vim /etc/sysctl.conf
在此檔案的最後一行增加 vm.max_map_count=262144
。
參考連結:https://www.elastic.co/guide/en/elasticsearch/reference/current/vm-max-map-count.html
vim /etc/security/limits.conf
es soft nproc 65536
es hard nproc 65536
參考檔案:https://www.elastic.co/guide/en/elasticsearch/reference/current/max-number-of-threads.html
以上設定設定完之後,重啟一下系統,使系統設定生效。
firewall-cmd --zone=public --add-port=9200/tcp --permanent
firewall-cmd --reload
需要使用非root
賬戶啟動。
bin/elasticsearch
前臺啟動
bin/elasticsearch -d
後臺啟動
[es@appbasic elasticsearch-8.4.3]$ bin/elasticsearch-reset-password --username elastic -i

server.host: "192.168.121.138"
# elasticsearch.hosts: ["https://192.168.121.138:9200"] 和 es使用者民密碼都不用設定
注意:
如果上方的設定中增加了 如下設定 ( elasticsearch.username
和 elasticsearch.password
) 或者 elasticsearch.hosts
) 則可能出現如下異常
`[2022-10-30T18:31:29.858+08:00][ERROR][elasticsearch-service] Unable to retrieve version information from Elasticsearch nodes. self signed certificate in certificate chain`
解決方案:
執行如下命令
bin/kibana-setup --enrollment-token <enrollment-token>
<enrollment-token>
通過如下命令獲取:bin/elasticsearch-create-enrollment-token --scope kibana
參考連結:https://www.elastic.co/guide/en/elasticsearch/reference/current/configuring-stack-security.html
bin/kibana
從上圖中可以 存取地址為 http://192.168.121.138:5601/?code=634917
點選藍色的按鈕,就開始設定 elastic 了。
