centos8 安装ElasticSearch

准备⼯作：

由于ElasticSearch 是java开发的所以需要安装Java的开发环境安装jdk

sudo yum search java-11

sudo yum install java-11-openjdk.x86_64 -y

安装 ElasticSearch 7.8

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.8.0-x86_64.rpmrpm -ivh elasticsearch-7.8.0-x86_64.rpm

这样就安装成功了

设置开机启动

systemctl daemon-reload # 重新加载systemd程序的配置⽂件systemctl enable elasticsearch.service # 设置开机⾃启动systemctl start elasticsearch.service # 启动服务[root@zhufanyu ~]# curl -XGET http://localhost:9200{

\"name\" : \"zhufanyu\

\"cluster_name\" : \"elasticsearch\

\"cluster_uuid\" : \"afsn8pUNT4ephGnrWadBMA\ \"version\" : {

\"number\" : \"7.8.0\

\"build_flavor\" : \"default\ \"build_type\" : \"rpm\

\"build_hash\" : \"757314695644ea9a1dc2fecd26d1a43856725e65\ \"build_date\" : \"2020-06-14T19:35:50.234439Z\ \"build_snapshot\" : false, \"lucene_version\" : \"8.5.1\

\"minimum_index_compatibility_version\" : \"6.0.0-beta1\" },

\"tagline\" : \"You Know, for Search\"}

配合ES

进⼊ES配置⽂件的⽬录 /etc/elasticsearch

elasticsearch.yml 是es的配置⽂件，jvm.options是jvm的配置⽂件node.name: node-1

cluster.initial_master_nodes: [\"node-1\"]

取消上⾯的注释, 保存退出重启ES

systemctl restart elasticsearch.service

开启远程访问连接

修改elasticsearch.yml 配置⽂件network.host: 0.0.0.0http.port: 9200

重启ES

防⽕墙开放9200端⼝，云服务器安全组规则⾥开放9200端⼝

访问ES
