ElasticSearch 7.5 安装配置集群

ray.lei开发，技术

软件下载地址： https://www.elastic.co/cn/start

根据自己的电脑系统选择对应版本下载安装/解压

开始配置config文件

实例中以一台主节点和一台边缘节点展开

主节点：config/elasticsearch.yml（仅启用的代码）

cluster.name: es-cluster #开始集群名称
node.name: node-1        #设置当前节点名称
node.master: true        #设置为主节点
network.host: 192.168.106.128   #固定ip地址
#http.port: 9200                #端口可使用默认9200
discovery.seed_hosts: ["192.168.106.128", "192.168.106.129"]   #设置主节点和子节点的ip地址
cluster.initial_master_nodes: ["node-1"]   #设置为主节点的名称即可

子节点：config/elasticsearch.yml（仅启用代码）

cluster.name: es-cluster #开始集群名称
node.name: node-2        #设置当前节点名称
node.master: false       #设置为子节点
network.host: 192.168.106.129   #固定ip地址
#http.port: 9200                #端口可使用默认9200
discovery.seed_hosts: ["192.168.106.128", "192.168.106.129"]   #设置主节点和子节点的ip地址
cluster.initial_master_nodes: ["node-1"]   #设置为主节点的名称即可

使用命令：bin/elasticsearch 启动主/子程序

至此，如上方状态返回结果。那么恭喜你配置成功！

静默运行：

要将Elasticsearch作为守护程序运行，请在命令行上指定-d，然后使用-p选项将进程ID记录在文件中： 

bin/elasticsearch -d -p pid

日志消息可以在$ ES_HOME / logs /目录中找到。

关闭Elasticsearch，停止pid文件中记录的进程ID 

pkill -F pid
