1. 安装配置JDK 8
（1）下载并解压缩
[root@node1 ~]# tar -zxvf jdk-8u112-linux-x64.tar.gz -C /opt
（2）编辑环境变量
vi /etc/profile.d/custom.sh
[root@node1 ~]# vi /etc/profile.d/custom.sh [root@node1 ~]# cat /etc/profile.d/custom.sh #!/bin/bash #java path export JAVA_HOME=/opt/jdk1.8.0_112 export PATH=$PATH:$JAVA_HOME/bin export CLASSPATH=.:$CLASSPATH:$JAVA_HOME/lib
（3）生效
[root@node1 ~]# source /etc/profile.d/custom.sh
（4）查看JDK版本
[root@node1 ~]# java -version java version "1.8.0_112" Java(TM) SE Runtime Environment (build 1.8.0_112-b15) Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode) [root@node1 ~]#2. ElasticSearch 6.x 软件包下载
（1）ElasticSearch 相关软件下载官网
https://www.elastic.co/cn/downloads
（2）下载ElasticSearch
https://www.elastic.co/downloads/elasticsearch
[root@node1 ~]# wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.1.0.tar.gz --2017-12-18 07:54:45-- https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.1.0.tar.gz Resolving artifacts.elastic.co (artifacts.elastic.co)... 184.73.156.41, 54.225.188.6, 54.235.82.130, ...

从5.0开始，ElasticSearch 安全级别提高了，不允许采用root帐号启动，所以我们要添加一个用户。
（1）创建es用户组
[root@node1 ~]# groupadd es
（2）创建用户es
useradd es（用户名） -g es（组名） -p es（密码）
[root@node1 ~]# useradd es -g es -p es
（3）修改权限
更改elasticsearch-6.1.0文件夹以及内部文件的所属用户以及组为es，-R表示逐级（N层目录）
[root@node1 ~]# chown -R es:es /opt/elasticsearch-6.1.04. 启动
（1）切换用户
[root@node1 ~]# su es
（2）启动ElasticSearch
[es@node1 root]$ cd /opt/elasticsearch-6.1.0/
[es@node1 elasticsearch-6.1.0]$ bin/elasticsearch

ctrl+c停止。
（3）后台运行
可以通过参数-d后台运行
[es@node1 elasticsearch-6.1.0]$ bin/elasticsearch -d
（4）查询进程
[es@node1 elasticsearch-6.1.0]$ jps 2327 Elasticsearch 2344 Jps [es@node1 elasticsearch-6.1.0]$5. 验证
使用curl验证
[es@node1 elasticsearch-6.1.0]$ curl localhost:9200
{
"name" : "MD1gu0h",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "MRAhTG8pR1mAif_tGg9qYg",
"version" : {
"number" : "6.1.0",
"build_hash" : "c0c1ba0",
"build_date" : "2017-12-12T12:32:54.550Z",
"build_snapshot" : false,
"lucene_version" : "7.1.0",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
[es@node1 elasticsearch-6.1.0]$
6.异常闪退解决办法
可能出现elasticsearch启动后，闪退现象。
[es@node1 elasticsearch-6.1.0]$ bin/elasticsearch -d [es@node1 elasticsearch-6.1.0]$ jps 2933 Jps 2918 Elasticsearch [es@node1 elasticsearch-6.1.0]$ jps 2947 Jps 2918 Elasticsearch [es@node1 elasticsearch-6.1.0]$ jps 3023 Jps [es@node1 elasticsearch-6.1.0]$
查看日志
[es@node1 elasticsearch-6.1.0]$ vi logs/elasticsearch.log
发现异常信息
[2017-12-18T08:57:49,869][INFO ][o.e.n.Node ] initialized

切换到root用户，
[root@node1 elasticsearch-6.1.0]# vi /etc/sysctl.conf
添加内容如下：
vm.max_map_count=262144
修改文件/etc/security/limits.conf
[root@node1 logs]# vi /etc/security/limits.conf
添加如下内容
* hard nofile 65536 * soft nofile 65536 * soft nproc 2048 * hard nproc 4096 # End of file
然后重启即可。
7.修改配置文件[es@node1 elasticsearch-6.1.0]$ vi config/elasticsearch.yml
修改network.host和http.port
# Set the bind address to a specific IP (IPv4 or IPv6): # network.host: 192.168.80.131 # # Set a custom port for HTTP: # http.port: 9200
保存退出。
8.再次启动（1）curl
[root@node1 ~]# curl 192.168.80.131:9200
{
"name" : "MD1gu0h",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "MRAhTG8pR1mAif_tGg9qYg",
"version" : {
"number" : "6.1.0",
"build_hash" : "c0c1ba0",
"build_date" : "2017-12-12T12:32:54.550Z",
"build_snapshot" : false,
"lucene_version" : "7.1.0",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
[root@node1 ~]#
（2）使用浏览器打开
如果在Windows平台通过浏览器打开，需要配置hosts。编辑C:\Windows\System32\drivers\etc\hosts
添加
192.168.80.131 node1
