Elasticsearch与jdk版本对应关系

一、 安装环境准备
主机规划：192.168.100.86 anolis8
系统配置：
4 VCPU、4G内存、50G硬盘
修改服务器名称:
hostnamectl set-hostname anolis8
需要修改几个参数，不然启动会报错
vim /etc/security/limits.conf
在末尾追加以下内容
* soft nofile 65536
* hard nofile 65536
* soft nproc 2048
* hard nproc 2048
* soft memlock unlimited
* hard memlock unlimited
对于systemd service的资源限制，现在放在 /etc/systemd/system.conf
vim /etc/systemd/system.conf
在末尾追加以下内容
DefaultLimitNOFILE=65536
DefaultLimitNPROC=32000
DefaultLimitMEMLOCK=infinity
否则elasticsearch启动时会报错：
memory locking requested for elasticsearch process but memory is not locked
这个问题的解决办法是修改
vim /usr/lib/systemd/system/elasticsearch.service
在文件中添加
LimitMEMLOCK=infinity
保存后退出
systemctl daemon-reload
二、安装配置
1、安装JDK
使用脚本安装jdk1.8版本
chmod +x jdkinstall.sh
sh jdkinstall.sh
source /etc/profile
[root@anolis8 ~]# java -version
java version "1.8.0_11"
Java(TM) SE Runtime Environment (build 1.8.0_11-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.11-b03, mixed mode)
2，安装elasticsearch
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.16.2-x86_64.rpm
[root@anolis8 ~]# rpm -ivh elasticsearch-7.16.2-x86_64.rpm

-rw-rw---- 1 root elasticsearch 0 12月 19 2021 users
-rw-rw---- 1 root elasticsearch 0 12月 19 2021 users_roles
2.1配置elasticsearch
创建elasticsearch data的存放目录，并修改该目录的属主属组
# mkdir -p /data/es-data (自定义用于存放data数据的目录)
# chown -R elasticsearch:elasticsearch /data/es-data
修改elasticsearch的日志属主属组
# chown -R elasticsearch:elasticsearch /var/log/elasticsearch
修改elasticsearch的配置文件
# vim /etc/elasticsearch/elasticsearch.yml
找到配置文件中的cluster.name，打开该配置并设置集群名称
17行
cluster.name: my-els
找到配置文件中的node.name，打开该配置并设置节点名称
node.name: anolis8 //192.168.100.86
修改data存放的路径
path.data: /data/es-data
修改logs日志的路径
path.logs: /var/log/elasticsearch
锁定物理内存地址，防止elasticsearch内存被交换出去,也就是避免es使用swap交换分区，频繁的交换，会导致IOPS变高；
bootstrap.memory_lock: true
监听的网络地址
network.host: 0.0.0.0
开启监听的端口
http.port: 9200
增加新的参数，这样head插件可以访问es
http.cors.enabled: true
http.cors.allow-origin: "*"
bootstrap.system_call_filter: false
集群发现
在启动此节点时，传递要执行发现的主机的初始列表：
discovery.seed_hosts: ["192.168.100.86"]
初始用来引导集群的符合主节点条件的节点列表：
cluster.initial_master_nodes: ["192.168.100.86"]
保存退出

可以看到elasticsearch启动所使用的java路径：/usr/share/elasticsearch/jdk/bin/java
查看java版本

elasticsearch使用的内存大小为2G，我们把它改小点：
修改参数：
vim /etc/elasticsearch/jvm.options
-Xms512m
-Xmx512m
启动
systemctl start elasticsearch.service

3、安装elasticsearch-head插件
通过github下载elasticsearch-head项目
npm安装 下载源码，编译安装，在nodejs环境下运行插件
# yum install git bzip2 -y
下载地址：
https://github.com/mobz/elasticsearch-head
https://codeload.github.com/mobz/elasticsearch-head/tar.gz/refs/tags/v5.0.0
通过浏览器下载elasticsearch-head-5.0.0.tar.gz然后上传后解压
tar -zxvf elasticsearch-head-5.0.0.tar.gz
ll

这个操作会把模块 'nodejs' 从流 '10' 切换到流 '16'
错误：无法切换已启用模块的流，除非显式的通过配置选项 module_stream_switch 启用。
推荐直接移除来自模块的所有已安装内容，然后通过 'dnf module reset <module_name>' 命令重置模块。在您重置模块之后，就可以安装其他的流。

deprecate karma@1.3.0 › core-js@^2.2.0 core-js@<3.23.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Some versions have web compatibility issues. Please, upgrade your dependencies to the actual version of core-js.

启动es-head插件,必须进入es-head插件目录运行启动命令
cd elasticsearch-head-5.0.0/
[root@anolis8 elasticsearch-head-5.0.0]# nohup npm run start &
使用浏览器访问http://192.168.100.86:9100/即可访问到es-head插件，再使用es-head插件访问es数据库，效果如下

http://192.168.100.86:9200/
注意
9100端口是插件端口，9200是es端口
通过插件访问http://192.168.100.86:9200点击连接还是失败，是因为es有安全机制只允许服务器本地访问，这时需要设置
设置跨域:
设置跨域同时也适用于安装的es-head插件跟es数据不在同一台服务器上时的情况
#编辑es主配置文件，在文本末尾添加如下两行配置
vim /etc/elasticsearch/elasticsearch.yml
# 是否支持跨域
http.cors.enabled: true
# *表示支持所有域名
http.cors.allow-origin: "*"
systemctl restart elasticsearch
cd elasticsearch-head-5.0.0/
nohup npm run start &
注意 ：别把es-head插件后放到 Elasticsearch的plugins目录下，否则会报错!!!
