思路：先安装elasticsearch:储存、索引，后安装kibana:展示，准备环境：三台物理机172.18.9.200,172.18.9.201,172.18.9.202，做elasticsearch集群：为保证效果特额外添加一块单独的500G的数据磁盘并格式化挂载到/esdata
一、检测Java版本，需在1.8.0以上方可！
[root@200/201/202 ~]#java -version
openjdk version "1.8.0_181"
OpenJDK Runtime Environment (build 1.8.0_181-b13)
OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)
二、[root@/200/201/202 src]#yum -y install elasticsearch-6.5.4.rpm
三、[root@200/201/202 src]#mkdir /esdata #创建存放path的目录
四、[root@200/201/202 ~]#vim /etc/elasticsearch/elasticsearch.yml
cluster.name:linux35 #三台name要一致，否则创建集群失败
node.name: node1 2 3
path.data: /esdata/data
path.logs: /esdata/logs
network.host: 0.0.0.0 #可以指定IP，也可以所以IP
http.port: 9200
discovery.zen.ping.unicast.hosts: ["172.18.9.200", "172.18.9.201","172.18.9.202"]
五、[root@200/201/202 ~]#fdisk -l #可知新建磁盘在/dev/sdb目录
Disk /dev/sdb: 21.5 GB, 21474836480 bytes, 41943040 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
[root@200/201/202 ~]# mkfs.xfs /dev/sdb #格式化新建磁盘
meta-data=/dev/sdb isize=512 agcount=4, agsize=32768000 blks
= sectsz=512 attr=2, projid32bit=1
= crc=1 finobt=0, sparse=0
data = bsize=4096 blocks=131072000, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0 ftype=1
log =internal log bsize=4096 blocks=64000, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
六、挂载至新建目录中，此时只要elasticsearch一旦启动，数据会写入/esdata/中，也就是写入/dev/sdb中
[root@200/201/202 ~]#mount /dev/sdb /esdata/
[root@200/201/202 ~]#
七、确保开机自动挂载：[root@200/201/202 ~]#vim /etc/fstab
/dev/sdb /esdata xfs defaults 0 0
八、此时还有可能会启动失败，可能是elasticsearch的权限导致的，所以修改权限：
[root@200/201/202 ~]#id elasticsearch
uid=988(elasticsearch) gid=982(elasticsearch) groups=982(elasticsearch)
[root@200/201/202 ~]#chown elasticsearch.elasticsearch /esdata/ -R #保证用户对/esdata/有读写权限
九、启动elasticsearch服务并访问，此时/esdata文件会有数据生成，(若没生成就是权限设置问题)：
[root@centos7 ~]#systemctl start elasticsearch
[root@centos7 ~]#ll /esdata/
total 0
drwxr-xr-x 3 elasticsearch elasticsearch 19 May 9 13:33 data
drwxr-xr-x 2 elasticsearch elasticsearch 195 May 9 13:33 logs
[root@centos7 ~]#ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 :::9200 :::
LISTEN 0 128 :::9300 ::: 
十、调整内存为2G:[root@200/201/202 ~]#vim /etc/elasticsearch/jvm.options
-Xms2g
-Xmx2g
[root@200/201/202 ~]#systemctl restart elasticsearch
十一、安装elasticsearch插件之head：
[root@200/201/202 ~]#vim /etc/elasticsearch/elasticsearch.yml
http.cors.enabled: true
http.cors.allow-origin: "*" #在文末添加！
[root@200/201/202 ~]#systemctl restart elasticsearch
十二、使用docker镜像安装head：
[root@200 yum.repos.d]#wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
在此处我的yum源配置有问题，所以我在某度上找到答案：安装了17.03版的docker：
[root@200 yum.repos.d]# yum install docker-ce-17.03.2.ce-1.el7.centos
[root@200 src]#ls
elasticsearch-head-docker.tar.gz #将docker的head包上传至src文件：
[root@200 src]#docker load -i /usr/local/src/elasticsearch-head-docker.tar.gz

[root@200 src]#docker images #查看镜像

十三、此时去访问172.18.9.200的9100的端口：
十四、在172.18.9.201主机安装kibana:(可以与elasticsearch不在一起)：
[root@201 ~]#yum install -y kibana-6.5.4-x86_64.rpm
[root@201 ~]#vim /etc/kibana/kibana.yml
server.port: 5601
server.host: "0.0.0.0"
elasticsearch.url: "http://172.18.9.200:9200" #可以是200主机的IP.
[root@201 ~]#systemctl start kibana
[root@201 ~]#systemctl enable kibana
Created symlink from /etc/systemd/system/multi-user.target.wants/kibana.service to /etc/systemd/system/kibana.service.
[root@201 ~]#ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 :5601 :*
十五、访问kibana的页面：
十六、再看elasticsearch-head：
