这东西用来做大数据检索，可以跟hadoop一起使用。
安装准备：
1.安装jdk
2.给虚拟机配置静态ip，可以查看其它博文怎么配置
3.开始安装：在centos7上操作
我把elasticsearch，放在了/usr/elasticsearch下面，到这个目录然后：
https://www.elastic.co/downloads/elasticsearch#preview-release 先去这里地址，找到rpm包，然后复制地址
执行：wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.0.0-beta1-x86_64.rpm
开始下载，挺大的得下一会儿
4.直接解压安装，超级方便，一步到位
rpm -ivh elasticsearch-2.3.5.rpm systemctl daemon-reloa//这个我没有执行成功，但是也没发现有什么影响
5.启动并查看安装状态，直接下载完解压，就可以启动起来
systemctl start elasticsearch systemctl status elasticsearch
6.启动的日志
[root@localhost elasticsearch]# systemctl status elasticsearch

7.然后去访问一下看看：
curl -XGET "127.0.0.1:9200" 或者运行 curl http://localhost:9200 curl http://127.0.0.1:9200 都可以
8.可以看到没问题
{

"cluster_name" : "elasticsearch",
"cluster_uuid" : "1QcPN8ZvQWKmeP-nP7UvkQ",
"version" : {
"number" : "7.0.0-beta1",
"build_flavor" : "default",

"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
9.但是这个时候从外面的浏览器访问，访问不了，这个时候这样配置，进入到下面的目录，然后编辑
elasticsearch.yml文件
node.name: node-1 前面的#打开
#network.host: 192.168.0.1
network.host: 192.168.136.110
#network.host: 0.0.0.0
#network.host: localhost
#network.host: 127.0.0.1 这里把network.host 设置为自己的ip地址 网上有设置成0.0.0.0的应该也可以自己设置一下试试
cluster.initial_master_nodes: ["node-1"] 这里一定要这样设置，我就是这里没有这样设置出问题的，弄了好久
在最后加上这两句，要不然，外面浏览器就访问不了哈

http.cors.allow-origin: "*"

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
# Before you set out to tweak and tune the configuration, make sure you
# understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
#cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /var/lib/elasticsearch
#
# Path to log files:
#
path.logs: /var/log/elasticsearch
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
"elasticsearch.yml" 98L, 3101C
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 192.168.0.1
network.host: 192.168.136.110
#network.host: 0.0.0.0
#network.host: localhost
#network.host: 127.0.0.1
#
# Set a custom port for HTTP:
#
#http.port: 9200
#http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1", "host2"]
#discovery.seed_hosts:["my-application"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
#cluster.initial_master_nodes: ["node-1", "node-2"]
cluster.initial_master_nodes: ["node-1"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
http.cors.enabled: true
http.cors.allow-origin: "*"
出了一些错误，具体是下面这几个
就是因上面的配置之前不对造成的，按照上面的配置完，再启动，就没有问题了
记录一下问题：
the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
一直都报这个错误，如果不配：
#cluster.initial_master_nodes: ["node-1", "node-2"]
cluster.initial_master_nodes: ["node-1"] 这个的话，这里的node-1是上面一个默认的记得打开就可以了

网上还有说ES启动不能用Root用户的，我跟着也新建了一个用户，但是最终发现，不用这个新建的 用户也行，所以应该是不用新建用户，直接用root用户就可以的
成功后可以试试：
[root@localhost elasticsearch]# curl http://192.168.136.110:9200
{
"name" : "node-1",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "1QcPN8ZvQWKmeP-nP7UvkQ",
"version" : {
"number" : "7.0.0-beta1",
"build_flavor" : "default",
"build_type" : "rpm",
"build_hash" : "15bb494",
"build_date" : "2019-02-13T12:30:14.432234Z",
"build_snapshot" : false,
"lucene_version" : "8.0.0",
"minimum_wire_compatibility_version" : "6.7.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
然后在浏览器上同样：http://192.168.136.110:9200/试一试就可以了
