Elasticsearch官方建议使用 Oracle的JDK8
1、下载安装
代码语言：javascript复制[root@vnode0 opt]# tar -zxvf elasticsearch-5.1.1.tar.gz
[root@vnode0 opt]# cd elasticsearch-5.1.1
[root@vnode0 elasticsearch-5.1.1]# ./bin/elasticsearch

[root@vnode0 elasticsearch-5.1.1]# 2、为elasticsearch创建用户和用户组
因为版本的问题，最新的版本安全级别提高了，不允许采用root帐号启动，所以我们要添加一个用户。
代码语言：javascript复制 [root@vnode0 elasticsearch-5.1.1]# useradd els
[root@vnode0 elasticsearch-5.1.1]# passwd els
Changing password for user els.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.创建用户组elasticsearch
代码语言：javascript复制 [root@vnode0 elasticsearch-5.1.1]# groupadd elasticsearch分配els用户到elasticsearch用户组
代码语言：javascript复制 [root@vnode0 elasticsearch-5.1.1]# usermod -G elasticsearch els给定用户权限。-R表示逐级（N层目录） ， * 表示 任何文件
代码语言：javascript复制 [root@vnode0 elasticsearch-5.1.1]# chown -R els.elasticsearch *更改目录的用户和用户组
代码语言：javascript复制 [root@vnode0 opt]# chown -R els:elasticsearch elasticsearch-5.1.1
[root@vnode0 opt]# ll
total 244048

-rw-r--r-- 1 root root 181352138 Dec 17 01:59 jdk-8u101-linux-x64.tar.gz
[root@vnode0 opt]# 3、修改host和port
代码语言：javascript复制 [root@vnode0 elasticsearch-5.1.1]# su els
[els@vnode0 elasticsearch-5.1.1]$
[els@vnode0 config]$ vi elasticsearch.yml
# Set the bind address to a specific IP (IPv4 or IPv6):
network.host: 192.168.1.180
# Set a custom port for HTTP:
http.port: 9200
# 增加新的参数，这样head插件可以访问es。设置参数的时候:后面要有空格
http.cors.enabled: true
http.cors.allow-origin: "*"4、修改limits.conf
代码语言：javascript复制 [els@vnode0 elasticsearch-5.1.1]$ ./bin/elasticsearch
