四、安装:Elasticsearch:

1. 安装java(在我的架构是安装过的)

Elasticsearch至少需要Java 8.版本的java,建议使用Oracle JDK 1.8.0_131版(官网建议)。如果没符合标准,请自行升级。本文只描述新安装java

[root@es-1 ~]# yum install -y java-1.8.0
[root@es-1 ~]# java -version
openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-b10)
OpenJDK 64-Bit Server VM (build 25.171-b10, mixed mode)
2.导入Elasticsearch PGP密钥
[root@es-1 ~]# rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
3.建立rpm包的repo
[root@es-1 ~]# vim /etc/yum.repos.d/elasticsearch.repo 

[elasticsearch-5.x]
name=Elasticsearch repository for 5.x packages
baseurl=https://artifacts.elastic.co/packages/5.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md
4.安装elasticsearch
[root@es-1 ~]# yum -y install elasticsearch
5.编辑配置文件(省略号代表有其他内容,但是不用修改)
[root@es-1 ~]# vim /etc/elasticsearch/elasticsearch.yml

# ---------------------------------- Cluster -----------------------------------
…………
#cluster.name: my-application
cluster.name: ELK               #起名三个节点要一致
…………
# ------------------------------------ Node ------------------------------------
…………
#node.name: node-1
node.name: es-1             #节点名:三个节点不一致
…………
# ---------------------------------- Network -----------------------------------
……
#network.host: 192.168.0.1
network.host: 192.168.205.155       #当前IP地址
#
# Set a custom port for HTTP:
#http.port: 9200                    #端口号:默认9200
……
# --------------------------------- Discovery ----------------------------------
…………
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
discovery.zen.ping.unicast.hosts: ["192.168.205.155","192.168.205.156","192.168.205.157"]
#集群节点IP地址

…………
6.启动、添加开机自启
[root@es-1 ~]# systemctl daemon-reload          #重载所有修改过的配置文件(刷新配置)
[root@es-1 ~]# systemctl start elasticsearch        #开启服务
[root@es-1 ~]# systemctl enable elasticsearch       #设置开机自启动
 [root@es-1 ~]#  systemctl status elasticsearch     #检查状态
● elasticsearch.service – Elasticsearch
   Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendor preset: disabled)
   Active: active (running) since 四 2018-05-24 10:20:04 CST; 3h 12min ago
7.查看端口状态
[root@es-1 ~]# netstat -ntlt
tcp6       0      0 192.168.205.155:9200    :::*                    LISTEN     
tcp6       0      0 192.168.205.155:9300    :::*                    LISTEN    

#9200是默认端口
#9300是集群通信端口

8.其他节点配置

es-2和es-3的安装和es-1步骤相同。不同之处为配置文件node.name:、network.host:

9.相关命令

•检查Elasticsearch是否运行

[root@es-1 ~]# curl -X GET "192.168.205.155:9200/"
{
  "name" : "es-1",
  "cluster_name" : "ELK",
  "cluster_uuid" : "JBdisD6qT_aEbCbz5eZo8Q",
  "version" : {
    "number" : "5.6.9",
    "build_hash" : "877a590",
    "build_date" : "2018-04-12T16:25:14.838Z",
    "build_snapshot" : false,
    "lucene_version" : "6.6.1"
  },
  "tagline" : "You Know, for Search"
}

•查询集群状态

[root@es-1 ~]# curl -XGET 'http://192.168.205.155:9200/_cat/nodes'  #任选一台机器执行
192.168.205.157 19 45 0 0.00 0.01 0.05 mdi - es-3
192.168.205.156 20 43 0 0.00 0.01 0.05 mdi - es-2
192.168.205.155 26 74 0 0.30 0.18 0.09 mdi * es-1   #带*号的是自动选举出来的master
 [root@es-1 ~]# curl -XGET 'http://192.168.205.155:9200/_cat/nodes?v'
ip      heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name

192.168.205.156  20          43   0    0.00    0.01     0.05 mdi       -   es-2
192.168.205.155  26          74   0    0.05    0.12     0.08 mdi       *   es-1
[root@es-1 ~]# curl -XGET 'http://192.168.205.155:9200/_cluster/state/nodes?pretty'
{
  "cluster_name" : "ELK",           #名字
  "nodes" : {
    "fkzXpqmxTkCFdYOUqkWw4g" : {            #ID值
      "name" : "es-3",                      #node名字
      "ephemeral_id" : "c0tVVqFvRUq9vBY0FAGW2Q",        #id
      "transport_address" : "192.168.205.157:9300", #集群通讯地址
      "attributes" : { }
    },
    "4ZbLhzt6Q5GK4kyICnYWHg" : {            #ID值
      "name" : "es-2",                      #node名字
      "ephemeral_id" : "E28qTcY_QxWHuZkENO9-gQ",        #id
      "transport_address" : "192.168.205.156:9300", #集群通讯地址
      "attributes" : { }
    },
    "SVXe8qm9RACCRl1Zb1qs8w" : {            #ID值
      "name" : "es-1",                      #node名字
      "ephemeral_id" : "w19b7MK_RO221SrwarV8Cg",        #id
      "transport_address" : "192.168.205.155:9300", #集群通讯地址
      "attributes" : { }
    }
  }
}

•查询集群中的master

[root@es-1 ~]# curl -XGET 'http://192.168.205.156:9200/_cluster/state/master_node?pretty'
{
  "cluster_name" : "ELK",
  "master_node" : "SVXe8qm9RACCRl1Zb1qs8w"
}
[root@es-1 ~]# curl -XGET 'http://192.168.205.155:9200/_cat/master?v'
id                     host            ip              node
SVXe8qm9RACCRl1Zb1qs8w 192.168.205.155 192.168.205.155 es-1

•查询集群的健康状态

[root@es-1 ~]# curl -XGET 'http://192.168.205.155:9200/_cat/health?v'
epoch      timestamp cluster status node.total node.data shards pri relo init unassign pending_tasks max_task_wait_time active_shards_percent
1527142257 14:10:57  ELK     green           3         3      0   0    0    0        0             0                  -                100.0%

###Status下边是状态显示

[root@es-1 ~]# curl -XGET 'http://192.168.205.155:9200/_cluster/health?pretty'
{
  "cluster_name" : "ELK",
  "status" : "green",           ##代表正常
  "timed_out" : false,
  "number_of_nodes" : 3,
  "number_of_data_nodes" : 3,
  "active_primary_shards" : 0,
  "active_shards" : 0,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0,
  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 100.0
}
10.相关文件路径

/etc/elasticsearch/elasticsearch.yml —主配置文件
/etc/elasticsearch/jvm.options —jvm参数配置文件
/etc/elasticsearch/log4j2.properties —-日志配置文件
/etc/sysconfig/elasticsearch —系统配置文件
/usr/share/elasticsearch/bin —二进制脚本文件
/var/lib/elasticsearch —在节点上分配的每个索引/分片的数据文件的位置。
/var/log/elasticsearch —日志文件位置

/usr/share/elasticsearch/plugins —插件目录
/etc/elasticsearch/scripts —脚本文件位置

至此elasticsearch集群布置结束
