es安装elasticsearch-sql插件（elasticsearch 安装）

根据现有ES版本，安装对应版本的插件

[es@hxl ~]$ cd elasticsearch
[es@hxl elasticsearch]$ ./bin/elasticsearch-plugin install https://github.com/NLPchina/elasticsearch-sql/releases/download/6.5.0.0/elasticsearch-sql-6.5.0.0.zip

安装完sql插件后，最好重启一下es!

2、安装elasticsearch-sql前端页面

2.1 安装及更新一些依赖包
[root@hxl ~]# yum -y install epel-release
[root@hxl ~]# yum -y install npm
[root@hxl ~]# yum -y update openssl

2.2 下载安装elasticsearch-sql前端页面，并使用node命令启动
[es@hxl ~]$ wget https://github.com/NLPchina/elasticsearch-sql/releases/download/5.4.1.0/es-sql-site-standalone.zip
[es@hxl ~]$ unzip es-sql-site-standalone.zip
[es@hxl ~]$ cd site-server/
[es@hxl site-server]$ npm install express --save
[es@hxl site-server]$ node node-server.js

2.3 启动成功后，直接访问es主机地址的8080端口即可

3、elasticsearch-sql前端web默认端口修改

有时候可能8080端口我们已经有在使用了，这样elasticsearch-sql就没办法正常启动了，需要修改一下配置文件，重新启动即可。
[es@hxl ~]$ vi site-server/site_configuration.json
{
"port":9090
}
[es@hxl ~]$

4、使用sql查询es数据报错Cannot POST /_sql处理

测试使用sql查询es索引数据，发现有如下报错：
Error:"<!DOCTYPE html>\n<html lang=\"en\">\n<head>\n<meta charset=\"utf-8\">
直接修改web页面右上角文本框中连接地址为es节点查询地址，然后直接点下方search重新查询即可
如下,地址后面必须带上/
http://192.168.1.136:19200/

5.遇到错误1
Error:Error occured! response is not avalible.
解决办法,修改es配置文件
http.cors.enabled: true
http.cors.allow-credentials: true
http.cors.allow-origin: "/.*/"
http.cors.allow-headers: WWW-Authenticate,X-Requested-With,X-Auth-Token,Content-Type,Content-Length,Authorization

6.安装了xpack不想输入用户名密码
修改elasticsearch.yml，添加：

xpack.security.enabled: false

7.用户密码验证访问
要是es部署了x-pack的话,需要用户和密码验证，则es-sql采用如下访问:
http://192.168.1.136:8080/?username=elastic&password=elastic&base_uri=http://192.168.1.136:19200

格式为:http://es-sql-host:8080/?username=elastic&password=elastic&base_uri=es-server:19200

CentOS 安装ElasticSearch-head插件

1 下载ElasticSearch-head安装包

1.1 Git下载ElasticSearch-head

#安装git,若机器环境已存在，不需要再次安装
yum install git
#下载
git clone https://github.com/mobz/elasticsearch-head.git


1.2 在GitHub上下载安装包
GitHub下载地址：https://github.com/mobz/elasticsearch-head
2 下载安装nodejs环境
elasticsearch-head是基于nodejs开发的，所以需要安装nodejs环境
2.1 直接安装nodejs
此方式安装过程较慢，主要是下载相关依赖由于网络原因会比较慢。
#安装nodejs环境，若机器环境已存在，不需要再次安装
yum install nodejs

2.2 手动安装配置nodejs
2.2.1 下载nodejs
--目前最新版本 Latest LTS Version: 12.18.3 (includes npm 6.14.6)
wget https://nodejs.org/dist/v12.18.3/node-v12.18.3-linux-x64.tar.gz

2.2.2 创建nodejs安装目录
mkdir /opt/nodejs

2.2.3 解压nodejs安装包
mv node-v12.18.3-linux-x64.tar.gz nodejs/
cd /opt/nodejs
tar -zxvf node-v12.18.3-linux-x64.tar.gz

2.2.4 配置nodejs环境变量
vim /etc/profile
配置nodejs 的HOME目录
export NODEJS_HOME=/opt/nodejsnode-v12.18.3-linux-x64
加入nodejs的环境变量
export PATH=$PATH:${NODEJS_HOME}/bin
让配置生效
source /etc/profile


2.2.5 测试nodejs的版本
node -v

3 安装ElasticSearch-head插件
3.1 使用npm安装
#安装 (elasticsearch-head目录下执行)
npm install

3.2 解压安装包并安装
# 安装unzip解压命令
yum install unzip
unzip elasticsearch-head-master.zip


4 配置ElasticSearch-head插件
# 修改服务器监听地址，增加hostname属性，设置为 hostname: '*'
vim /opt/elasticsearch-head-master/Gruntfile.js
connect: {

server: {

options: {

port: 9100,

hostname: '*',

base: '.',

keepalive: true

}

}

}


#修改默认elasticsearch服务连接地址，将localhost修改为elasticsearch的服务器地址
vim /opt/elasticsearch-head-master/_site/app.js

init: function(parent) {
		this._super();
		this.prefs = services.Preferences.instance();
		this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://es服务器ip地址:9200";
}

vi /opt/elasticsearch/config/elasticsearch.yml
#若连接不上elasticsearch服务，请检查、修改Elasticsearch配置,允许跨域访问，修改后重新启动Elasticsearch,添加如下配置，支持跨域访问
http.cors.enabled: true
http.cors.allow-origin: "*"

5 启动ElasticSearch-head
# elasticsearch-head目录下执行
npm run start

6 访问

CentOS6.5安装elasticsearch-5.5.1以及elasticsearch-sql插件安装

首先下载

elasticsearch包下载地址:点击跳转官网

上传到服务器并且解压.
修改配置文件 elasticsearch.yml (其他根据需要配置)

#集群名称
cluster.name: myes
#节点名字
node.name: myes01
#数据位置
path.data: /usr/java/elk/elasticsearch-5.5.1/espath/data
#日志位置
path.logs: /usr/java/elk/elasticsearch-5.5.1/espath/logs
#本机IP
network.host: 192.168.80.123
#可以选取的节点(如果是多台就["lijie","lijie1","lijie2"])但是必须是基数个
discovery.zen.ping.unicast.hosts: ["lijie"]

#这两个配置是支持跨域访问用的
http.cors.allow-origin: "/.*/"
http.cors.enabled: true

启动es

/usr/java/elk/elasticsearch-5.5.1/bin/elasticsearch -d

报错:

Elasticsearch requires at least Java 8 but your Java version from /usr/java/jdk1.7.0_79/bin/java does not meet this requirement

解决:
最低只支持JDK1.8,换成JDK8就行

启动失败,查看日志,es和solr一样不允许用root用户启动，切换一个用户即可:

查看内核版本:

[root@lijie ~]# cat /proc/version
Linux version 2.6.32-431.el6.x86_64 (mockbuild@c6b8.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) ) #1 SMP Fri Nov 22 03:15:09 UTC 2013

问题:
linux的内核版本过低

升级linux内核

首先导入publicKey:

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

然后执行

rpm -Uvh http://www.elrepo.org/elrepo-release-6-8.el6.elrepo.noarch.rpm

安装kmod-r8168

yum install -y kmod-r8168

然后:

yum --enablerepo=elrepo-kernel install kernel-lt -y

然后:

vi /etc/grub.conf
#将第一个default的值改为0  -> default=0

然后重启:

reboot

重启后再查看内核版本:

[root@lijie ~]# cat /proc/version
Linux version 3.10.107-1.el6.elrepo.x86_64 (mockbuild@Build64R6) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-18) (GCC) ) #1 SMP Tue Jun 27 10:57:54 EDT 2017

重新启动,还是报错,查看日志文件:

错误内容如下:

bootstrap checks Failed
[1]: max file descriptors [4096] for elasticsearch process is too low,increase to at least [65536]
[2]: max number of threads [1024] for user [hadoop] is too low,increase to at least [2048]
[3]: max virtual memory areas vm.max_map_count [65530] is too low,increase to at least [262144]

三个错误的解决方案:

其中[1]: max file descriptors [4096] for elasticsearch process is too low,increase to at least [65536]
解决方法:

#用root用户执行
vi /etc/security/limits.conf 

#添加
* soft    nofile  65536
* hard    nofile  131072

其中[2]: max number of threads [1024] for user [hadoop] is too low,increase to at least [2048]
解决方法:

#用root用户执行
vi /etc/security/limits.d/90-nproc.conf 

#修改
*          soft    nproc     1024 为 2048

其中[3]: max virtual memory areas vm.max_map_count [65530] is too low,increase to at least [262144]
解决方法:

#用root用户执行
vi /etc/sysctl.conf 

#添加一条配置:
vm.max_map_count=262144

#然后执行:
sysctl -p

解决上面的错误之后重启elasticsearch
/usr/java/elk/elasticsearch-5.5.1/bin/elasticsearch -d

注意事项: 用root用户做完上面的修改后再切回普通用户,这样上面的配置才能生效,不然还是会报错

安装特别简单,就是新版本的安装可能会遇到上述的问题.

安装sql插件（详见：https://github.com/NLPchina/elasticsearch-sql/）：

[hadoop@lijie elasticsearch-5.5.1]$ ./bin/elasticsearch-plugin install https://github.com/NLPchina/elasticsearch-sql/releases/download/5.5.1.0/elasticsearch-sql-5.5.1.0.zip

[hadoop@lijie site-server]$ wget https://github.com/NLPchina/elasticsearch-sql/releases/download/5.4.1.0/es-sql-site-standalone.zip

[hadoop@lijie site-server]$ unzip es-sql-site-standalone.zip

下载nodejs（http://nodejs.cn/download/）：

上传解压：
[root@lijie nodejs]# xz -d node-v8.7.0-linux-x64.tar.xz
[root@lijie nodejs]# tar -xvf node-v8.7.0-linux-x64.tar 

然后创建软链接：
[root@lijie node-v8.7.0-linux-x64]# ln -s /usr/nodejs/node-v8.7.0-linux-x64/bin/npm /usr/local/bin/ 


[root@lijie node-v8.7.0-linux-x64]# ln -s /usr/nodejs/node-v8.7.0-linux-x64/bin/node /usr/local/bin/ 

[root@lijie node-v8.7.0-linux-x64]# node -v
v8.7.0

在site-server目录下：

[hadoop@lijie site-server]$ npm install express --save

[hadoop@lijie site-server]$ node node-server.js

最后重启es并且查询：

#访问
http://192.168.80.123:9200/_sql?sql=select * from school where score > 90

centos安装Elasticsearch

一、yum安装：

　　1. 在/etc/yum.repos.d/目录创建文件elasticsearch.repo

　　2. 添加以下内容

[elasticsearch-6.x]
name=Elasticsearch repository for 6.x packages
baseurl=https://artifacts.elastic.co/packages/6.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

　　3. 执行yum命令：sudo yum install elasticsearch -y

　　4. 设置开机启动：sudo chkconfig --add elasticsearch

　　5. 启动：sudo -i service elasticsearch start

　　　　-- 关闭 sudo -i service elasticsearch stop

　　　　-- 重启 sudo -i service elasticsearch restart

二、测试项目是否运行

　　-- curl -X GET ‘http://localhost:9200/?pretty‘　　

　　返回结果类似如下显示：

{
  "name" : "Cp8oag6","cluster_name" : "elasticsearch","cluster_uuid" : "AT69_T_DTp-1qgIJlatQqA","version" : {
    "number" : "6.4.3","build_flavor" : "default","build_type" : "zip","build_hash" : "f27399d","build_date" : "2016-03-30T09:51:41.449Z","build_snapshot" : false,"lucene_version" : "7.4.0","minimum_wire_compatibility_version" : "1.2.3","minimum_index_compatibility_version" : "1.2.3"
  },"tagline" : "You KNow,for Search"
}

三、更改配置，增加远程访问

　　-- 配置文件目录：/etc/elasticsearch/

　　-- elasticsearch.yml文件增加如下属性：

　　　　- network.host: 0.0.0.0

[root@dev18 bin]# ./elasticsearch -d

遇到问题（不能以root账号进行启动elasticSearch） --

Exception in thread "main" java.lang.RuntimeException: don''t run elasticsearch as root.

详细问题如下：

[root@dev18 bin]# ./elasticsearch -d
[root@dev18 bin]# Exception in thread "main" java.lang.RuntimeException: don''t run elasticsearch as root.
	at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:94)

	at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:286)
	at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:35)
Refer to the log for complete error details.

针对上述问题（don''t run elasticsearch as root.），本文给出两种解决方案~

解决方法

方法1

在启动elasticsearch的时候，指定允许root启动~ 如：

[root@dev18 bin]# ./elasticsearch -Des.insecure.allow.root=true

[root@dev18 bin]# ./elasticsearch -Des.insecure.allow.root=true

这种方式能够启动，但是elasticsearch会提示，使用ROOT账户运行，这是一个不好的主意。

[WARN ][bootstrap ] running as ROOT user. this is a bad idea!

方法2

鉴于方法1不是一个很好的方式，我们应该寻求其它的方法 --

创建一个elasticsearch相关的账号~

（1）首先，创建一个分组，取名为esgroup，然后，往该分组中添加用户es，并设置es账户的密码。

[root@dev18 bin]# groupadd esgroup
[root@dev18 bin]# useradd -g esgroup es
[root@dev18 bin]# passwd es
Changing password for user es.
New password: 
Retype new password: 
passwd: all authentication tokens updated successfully.
[root@dev18 bin]#

（2）修改elasticsearch目录权限~

[root@dev18 elasticsearch]# chown -R root .
[root@dev18 elasticsearch]# chown -R es .
[root@dev18 elasticsearch]# chgrp -R esgroup .

（3）使用新创建的账号es来登录终端，并使用 ./elasticsearch -d命令启动elasticsearch

[es@dev18 ~]$ cd /srv/elasticsearch
[es@dev18 elasticsearch]$ cd bin
[es@dev18 bin]$ ./elasticsearch -d

（4）验证

在方法2中，通过前面的（1）、（2）、（3）三个步骤之后，elasticsearch已经运行~

所以，我们需要做一下验证，看elasticsearch是否正常启动~

使用ps -ef|grep elasticsearch查看进程~

[es@dev18 bin]$ ps -ef|grep elasticsearch
es        1656     1 29 09:17 pts/3    00:00:09 /usr/java/jdk1.7.0_71/bin/java -Xms256m -Xmx1g -Djava.awt.headless=true -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+HeapDumpOnOutOfMemoryError -XX:+DisableExplicitGC -Dfile.encoding=UTF-8 -Djna.nosys=true -Des.path.home=/srv/elasticsearch -cp /srv/elasticsearch/lib/elasticsearch-2.4.0.jar:/srv/elasticsearch/lib/* org.elasticsearch.bootstrap.Elasticsearch start -d
es        1714  1624  0 09:18 pts/3    00:00:00 grep elasticsearch
[es@dev18 bin]$

使用curl -X GET http://localhost:9200查看信息~

[es@dev18 bin]$ curl -X GET http://localhost:9200
{
  "name" : "George Tarleton",
  "cluster_name" : "elasticsearch",
  "version" : {
    "number" : "2.4.0",
    "build_hash" : "ce9f0c7394dee074091dd1bc4e9469251181fc55",
    "build_timestamp" : "2016-08-29T09:14:17Z",
    "build_snapshot" : false,
    "lucene_version" : "5.5.2"
  },
  "tagline" : "You Know, for Search"
}
[es@dev18 bin]$

至此，默认条件配置的elasticsearch就成功了~ 后续就可以玩elasticsearch相关的其它功能了~~
