Linux 安装 Elasticsearch 并配置

下载 Elasticsearch

Elasticsearch 下载地址 www.elastic.co/downloads/elasticsearch

由于国外一般下载比较慢, 可以使用国内镜像：www.newbe.pro/tags/Mirrors/

同样还有其他开源软件可供下载:

• filebeat：www.newbe.pro/Mirrors/Mirrors-Filebeat/
• elasticsearch: www.newbe.pro/Mirrors/Mirrors-Elasticsearch/
• Kibana: www.newbe.pro/Mirrors/Mirrors-Kibana/
• Logstash: www.newbe.pro/Mirrors/Mirrors-Logstash/
• RabbitMQ: www.newbe.pro/Mirrors/Mirrors-RabbitMQ/

Elasticsearch Linux 安装

环境 Centos 7

首先需要到[国内镜像网站](https://mirrors.huaweicloud.com/home) 查找自己需要的 Elasticsearch 版本, 下载其压缩包, 我这边选择 elasticsearch-7.8.0-linux-x86_64.tar.gz

# 下载 Elasticsearch 压缩包
wget https://mirrors.huaweicloud.com/elasticsearch/7.8.0/elasticsearch-7.8.0-linux-x86_64.tar.gz

# 解压 并 进入 es 文件夹
tar -zxvf elasticsearch-7.8.0-linux-x86_64.tar.gz && cd elasticsearch-7.8.0

配置文件

解压成功过后, 需要配置 elasticsearch.yml 文件, 才能正常对外提供服务

# 配置文件 以下内容
vim config/elasticsearch.yml

# -----------------
node.name: node-1

# 一定要对应上面 node.name 设置
cluster.initial_master_nodes: ["node-1"] 

# network.host 设置为自己的ip地址 也可以设置成0.0.0.0（代表所有ip可以访问）
network.host: 127.0.0.1
http.port: 9200

# 在最后加上这两句，要不然，外面浏览器就访问不了哈
http.cors.enabled: true
http.cors.allow-origin: "*"
# -----------------

启动 elasticsearch

elasticsearch.yml 文件配置完成过后, 就可以使用命令 ./bin/elasticsearch 尝试启动

打印信息结果出来 publish_address, bound_addresses 提供服务 ip 与 端口, started 以启动字样, 意味着启动成功
