# ES与 Kibana安装部署 #

## 一、ElasticSearch安装部署 ##

### 1.1 安装包下载 ###

1）ElasticSearch官网： https://www.elastic.co/cn/downloads/elasticsearch  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80Mjc5NjQwMw_size_16_color_FFFFFF_t_70]

### 1.2 ElasticSearch安装 ###

#### 1.2.1 解压安装ElasticSearch ####

1）解压elasticsearch-6.6.0.tar.gz到/opt/module目录下

[hadoop@hadoop102 software]$ tar -zxvf elasticsearch-6.6.0.tar.gz -C /opt/module/
    [hadoop@hadoop102 module]$

2）在/opt/module/elasticsearch路径下创建data文件夹

[hadoop@hadoop102 elasticsearch]$ mkdir data

3）修改配置文件/opt/module/elasticsearch/config/elasticsearch.yml

[hadoop@hadoop102 config]$ pwd
    /opt/module/elasticsearch/config
    [hadoop@hadoop102 config]$ vi elasticsearch.yml
    
    #-----------------------Cluster-----------------------
    cluster.name: my-application
    #-----------------------Node-----------------------
    node.name: node-102
    #-----------------------Paths-----------------------
    path.data: /opt/module/elasticsearch/data
    path.logs: /opt/module/elasticsearch/logs
    #-----------------------Memory-----------------------
    bootstrap.memory_lock: false
    bootstrap.system_call_filter: false
    #-----------------------Network-----------------------
    network.host: 192.168.6.102 
    #-----------------------Discovery-----------------------
    discovery.zen.ping.unicast.hosts: ["192.168.1.102"]

**（1）cluster.name**

如果要配置集群需要两个节点上的elasticsearch配置的cluster.name相同，都启动可以自动组成集群，这里如果不改cluster.name则默认是cluster.name=my-application，

**（2）nodename随意取但是集群内的各节点不能相同**

**（3）修改后的每行前面不能有空格，修改后的“：”后面必须有一个空格**

**4）修改配置文件/opt/module/elasticsearch/config/jvm.options**

修改
    -Xms1g
    -Xmx1g
    为
    -Xms256m
    -Xmx256m

分发至hadoop103以及hadoop104，分发之后修改：

[hadoop@hadoop102 module]$ xsync elasticsearch/
    
    node.name: node-103
    network.host: 192.168.1.103
    
    node.name: node-104
    network.host: 192.168.1.104

#### 1.2.2 配置linux系统环境 ####

（参考：http://blog.csdn.net/satiling/article/details/59697916）

1）切换到root用户，编辑limits.conf 添加类似如下内容

[root@hadoop102 elasticsearch]# vi /etc/security/limits.conf
    添加如下内容:
    * soft nofile 65536
    * hard nofile 131072
    * soft nproc 2048
    * hard nproc 4096
    注意：“*” 不要省略掉

2）切换到root用户，进入limits.d目录下修改配置文件。（CentOS7.x不用改）

[root@hadoop102 elasticsearch]# vi /etc/security/limits.d/90-nproc.conf
    修改如下内容：
    * soft nproc 1024
    #修改为
    * soft nproc 4096

3）切换到root用户修改配置sysctl.conf

[root@hadoop102 elasticsearch]# vi /etc/sysctl.conf
    添加下面配置：
    vm.max_map_count=655360
    并执行命令：
    [root@hadoop102 elasticsearch]# sysctl -p
    以上修改的Linux配置需要分发至其他节点
    [root@hadoop102 elasticsearch]# xsync /etc/security/limits.conf
    
    [root@hadoop102 elasticsearch]# xsync /etc/security/limits.d/90-nproc.conf #(Centos7.X不需要)
    
    [root@hadoop102 elasticsearch]# xsync /etc/sysctl.conf

然后，重新启动Linux，必须重启！！！  
4）启动Elasticsearch

[hadoop@hadoop102 elasticsearch]$ bin/elasticsearch

5）测试elasticsearch

[hadoop@hadoop102 elasticsearch]$ curl http://hadoop102:9200
    { 
      "name" : "node-102",
      "cluster_name" : "my-application",
      "cluster_uuid" : "w9UFspEFR4-F5gLrTYMHIw",
      "version" : { 
        "number" : "6.6.0",
        "build_flavor" : "default",
        "build_type" : "tar",
        "build_hash" : "a9861f4",
        "build_date" : "2019-01-24T11:27:09.439740Z",
        "build_snapshot" : false,
        "lucene_version" : "7.6.0",
        "minimum_wire_compatibility_version" : "5.6.0",
        "minimum_index_compatibility_version" : "5.0.0"
      },
      "tagline" : "You Know, for Search"
    }

或者在浏览器中访问http://hadoop102:9200

8）停止集群

kill -9 进程号

9）群起脚本

[hadoop@hadoop102 bin]$ vi es.sh
    #!/bin/bash
    es_home=/opt/module/elasticsearch
    case $1  in
     "start") { 
      for i in hadoop102 hadoop103 hadoop104
      do
        echo "==============$i=============="
    ssh $i  "source /etc/profile;${es_home}/bin/elasticsearch >/dev/null 2>&1 &"
    sleep 4s;
      done
    
    };;
    "stop") { 
      for i in hadoop102 hadoop103 hadoop104
      do
        echo "==============$i=============="
        ssh $i "ps -ef|grep $es_home |grep -v grep|awk '{print \$2}'|xargs kill" >/dev/null 2>&1
      done
    
    };;
    esac

### 1.3 ElasticSearch操作工具 ###

#### 1.3.1 浏览器 ####

查看集群节点：浏览器中输入hadoop102:9200/\_cat/nodes

## 二、Kibana ##

Kibana的安装  
将kibana压缩包上传到虚拟机指定目录

[hadoop@hadoop102 software]$ tar -zxvf kibana-6.6.0-linux-x86_64.tar.gz -C /opt/module/
    [hadoop@hadoop102 module]$ mv kibana-6.6.0-linux-x86_64/ kibana/
    修改相关配置，连接Elasticsearch
    [hadoop@hadoop102 kibana]$ vi config/kibana.yml
    
    # Kibana is served by a back end server. This setting specifies the port to use.
    server.port: 5601
    # Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values.
    # The default is 'localhost', which usually means remote machines will not be able to connect.
    # To allow connections from remote users, set this parameter to a non-loopback address.
    server.host: "192.168.6.102"
    ... ...
    ... ...
    # The URL of the Elasticsearch instance to use for all your queries.
    elasticsearch.hosts: "http://192.168.6.102:9200"

启动Kibana

[hadoop@hadoop102 kibana]$ bin/kibana

浏览器访问hadoop102:5601  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80Mjc5NjQwMw_size_16_color_FFFFFF_t_70 2]

修改之前的ES启动脚本为：

#!/bin/bash
    es_home=/opt/module/elasticsearch
    kibana_home=/opt/module/kibana
    case $1  in
     "start") { 
      for i in hadoop102 hadoop103 hadoop104
      do
        echo "==============$i=============="
    ssh $i  "source /etc/profile;${es_home}/bin/elasticsearch >/dev/null 2>&1 &"
    sleep 4s;
      done
      sleep 2s;
      nohup ${kibana_home}/bin/kibana > kibana.log 2>&1 &
    };;
    "stop") { 
      ps -ef | grep ${kibana_home} | grep -v grep | awk '{print $2}'| xargs kill
      for i in hadoop102 hadoop103 hadoop104
      do
        echo "==============$i=============="
        ssh $i "ps -ef|grep $es_home |grep -v grep|awk '{print \$2}'|xargs kill" >/dev/null 2>&1
      done
    };;
    esac

Kibana的Dev Tools  
在操作窗口输入 GET \_cat/nodes
