ElasticSearch（ES）学习【一】——环境搭建、安装配置

话不多说，先贴上ElasticSearch权威指南中文版,里面还有ES谷歌插件和ES的安装包

1、安装虚拟机（linux环境，我是centos 7)

2、安装java环境，jdk啥的一通配  https://pan.baidu.com/s/1n-4nIytk0sAMm1dsiRNzCw

3、下载安装ES

官方下载地址：https://www.elastic.co/cn/downloads/elasticsearch   

刚装的centos系统 ，安装rz sz命令便于传文件，然后 rz命令把jdk和es都传到linux上

[root@localhost /]# yum -y install lrzsz
[root@localhost /]# rz

解压缩，修改es文件夹的操作用户为非root用户（es不支持root用户启动), ****是你要用的用户名，运行bin下的elasticsearch

[root@localhost es]# tar -zxvf elasticsearch-7.3.1-linux-x86_64.tar.gz 
[root@localhost es]# chown -R ****.**** elasticsearch-7.3.1
[root@localhost es]# cd elasticsearch-7.3.1
[root@localhost bin]# su guobaoyu
[guobaoyu@localhost elasticsearch-7.3.1]# ./bin/elasticsearch

此时连接es就可以看到信息：（刚才启动es的命令行不能关，换个命令行连接es）

[root@localhost ~]# curl 127.0.0.1:9200/
{
  "name" : "localhost.localdomain",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "_LHpv4p4RfCpLHbqCM6RHw",
  "version" : {
    "number" : "7.3.1",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "4749ba6",
    "build_date" : "2019-08-19T20:19:25.651794Z",
    "build_snapshot" : false,
    "lucene_version" : "8.1.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

[guobaoyu@localhost elasticsearch-7.3.1]# ./bin/elasticsearch -d就可以后台作为守护线程启动es,无需切换命令行
