原文：https://www.geek-share.com/detail/2724606887.html

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 ~]#

如果JDK版本不正确，比如

[root@node1 ~]# java -version
openjdk version "1.8.0_161"
OpenJDK Runtime Environment (build 1.8.0_161-b14)
OpenJDK 64-Bit Server VM (build 25.161-b14, mixed mode)
[root@node1 ~]#

这是因为自带的JDK的原因，我们只需要删除自带JDK即可

[root@node1 ~]# rpm -qa|grep java|xargs rpm -e --nodeps
[root@node1 ~]# rpm -qa|grep java

再重新执行source 命令即可。

2. 创建用户

从5.0开始，ElasticSearch 安全级别提高了，不允许使用root账号启动，所以我们要添加一个用户。

（1）创建bigdata 用户组

[root@node1 ~]# groupadd bigdata

（2）创建用户es

[root@node1 ~]# useradd es
[root@node1 ~]# passwd es
Changing password for user es.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
[root@node1 ~]#

（3）将es用户添加到bigdata组

[root@node1 ~]# usermod -G bigdata es

（4）设置sudo权限

[root@node1 ~]# visudo

找到root ALL=(ALL) ALL一行，添加es用户，如下。

## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL
es      ALL=(ALL)       ALL

（5）切换用户

[root@node1 ~]# su es
[es@node1 root]$ cd
[es@node1 ~]$

3. ElasticSearch 6.x 软件包下载

（1）ElasticSearch官网 https://www.elastic.co/cn/downloads

（2）下载ElasticSearch
https://www.elastic.co/downloads/elasticsearch

[es@node1 ~]$ wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.1.1.tar.gz
--2018-01-06 08:24:06--  https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.1.1.tar.gz

[es@node1 ~]$

（3）解压缩
tar -zxvf elasticsearch-6.1.1.tar.gz

[es@node1 ~]$ tar -zxvf elasticsearch-6.1.1.tar.gz

[es@node1 ~]$ sudo mv elasticsearch-6.1.1 /opt

（4）修改目录权限
更改elasticsearch-6.1.1文件夹以及内部文件的所属用户为es, 用户组组为bigdata，-R表示逐级（N层目录）

[es@node1 ~]$ sudo chown -R es:bigdata /opt/elasticsearch-6.1.1
[es@node1 ~]$ ll /opt/elasticsearch-6.1.1
total 220
drwxr-xr-x  2 es bigdata   4096 Jan  6 08:35 bin
drwxr-xr-x  2 es bigdata     75 Dec 17 15:24 config
drwxr-xr-x  2 es bigdata   4096 Dec 17 15:24 lib
-rw-r--r--  1 es bigdata  11358 Dec 17 15:22 LICENSE.txt
drwxr-xr-x 15 es bigdata    272 Dec 17 15:24 modules
-rw-r--r--  1 es bigdata 191887 Dec 17 15:24 NOTICE.txt
drwxr-xr-x  2 es bigdata      6 Dec 17 15:24 plugins
-rw-r--r--  1 es bigdata   9326 Dec 17 15:22 README.textile
[es@node1 ~]$

ElasticSearch 配置

（1）修改elasticsearch.yml

[es@node1 elasticsearch-6.1.1]$ 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。

（2）修改/etc/sysctl.conf
切换到root用户

[root@node1 elasticsearch-6.1.1]# vi /etc/sysctl.conf

添加内容如下：

vm.max_map_count=262144

或者使用sed命令在文件最后添加一行配项

[root@node1 elasticsearch-6.1.1]# sed -i '$a\vm.max_map_count=262144' /etc/sysctl.conf

使用命令sysctl -p 生效

[root@node1 ~]# sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 68719476736
kernel.shmall = 4294967296
vm.max_map_count = 262144
[root@node1 ~]#

（3）修改文件/etc/security/limits.conf

[root@node1 logs]# vi /etc/security/limits.conf

添加内容如下

* hard nofile 65536
* soft nofile 65536

* soft nproc 2048
* hard nproc 4096

# End of file

5. ElasticSearch 启动与停止

（1）直接启动
