1）下载
Elasticsearch 6.3.1 地址：https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.3.1.tar.gz
2）拷贝
拷贝到服务器上，解压：tar -xvzf elasticsearch-6.3.1.tar.gz 。解压后路径：/home/elasticsearch-6.3.1
3）创建用户
创建用户，创建esdata目录，并赋予权限
[root@bogon home]# adduser esuser
[root@bogon home]# cd /home
[root@bogon home]# mkdir -p esdata/data
[root@bogon home]# mkdir -p esdata/log
[root@bogon home]# chown -R esuser elasticsearch-6.3.1
[root@bogon home]# chown -R esuser esdata4）配置es
[root@bogon esdata]# cat /home/elasticsearch-6.3.1/config/elasticsearch.yml
# ======================== 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: /home/esdata/data
#
# Path to log files:
#
path.logs: /home/esdata/log
#
# ----------------------------------- 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: 0.0.0.0
#
# Set a custom port for HTTP:
#
http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
discovery.zen.ping.unicast.hosts: ["host1", "host2"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes:
#
# For more information, consult the zen discovery 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: true5）配置系统
[root@bogon bin]# vim /etc/security/limits.conf（在文件最后添加）
esuser hard nofile 65536
esuser soft nofile 65536
esuser soft memlock unlimited
esuser hard memlock unlimited以上配置解决问题：
max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
memory locking requested for elasticsearch process but memory is not locked
[root@bogon bin]# sysctl -w vm.max_map_count=262144
vm.max_map_count = 262144
[root@bogon bin]# more /proc/sys/vm/max_map_count
262144以上配置解决问题：
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144][root@bogon logs]# visudo
。。。。。。。。
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
esuser ALL=(ALL) ALL
。。。。。。。。以上配置解决某些情况下无法读写的问题
6）启动
[root@bogon ~]# cd /home/elasticsearch-6.3.1/bin/
[root@bogon bin]# su esuser
[esuser@bogon bin]$ ./elasticsearch

7）验证
浏览器访问：http://192.168.20.115:9200/ （192.168.20.115是es服务器的IP，另外请确保9200端口能够被外部访问），返回：
{
"name" : "node-1",
"cluster_name" : "my-application",
"cluster_uuid" : "_na_",
"version" : {
"number" : "6.3.1",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "eb782d0",
"build_date" : "2018-06-29T21:59:26.107521Z",
"build_snapshot" : false,
"lucene_version" : "7.3.1",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
当然最方便的安装方法还是下载docker镜像，官方安装手册：https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html 步骤：
1）下载镜像：docker pull docker.elastic.co/elasticsearch/elasticsearch:6.3.1
2）运行容器：docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:6.3.1
ElasticSearch Head安装
官方的模拟工具是控制台的curl，不是很直观，可以在chrome浏览器中安装head插件来作为请求的工具：head插件的地址：https://chrome.google.com/webstore/detail/elasticsearch-head/ffmkiejjmecolpfloofpjologoblkegm/
