启动el和head都没错 但现实未连接 修改
vi Gruntfile.js
修改服务器监听地址(Gruntfile.js)
connect: {
server: {
options: {
port: 9100,
hostname: '*',
base: '.',
keepalive: true
}
}
}
增加这一行：增加hostname属性，设置为*
修改连接地址(app.js)
cd /usr/local/elk/es-head/elasticsearch-head-master/_site
vi app.js
修改head的连接地址:
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://localhost:9200";
把localhost修改成你es的服务器地址，如:
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://172.30.1.45:9200";
Linux 出现-bash: grunt: command not found 错误解决
1、安装grunt
npm install -g grunt-cli
1
2、使用命令
[root@localhost ~]# grunt -version
-bash: grunt: command not found
1
2
3、分析
如果一些程序没有安装在系统默认的路径(ie /bin/, /usr/bin, /usr/local/bin/ )里面，这个时候普通用户想要调用这些命令，必须设定路径。
[root@localhost ~]# vi ~/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin:/usr/local/src/node-v8.2.1-linux-x86/bin
export PATH

之前装过2.X版本，里面的elasticsearch-head组件是集成到版本里的，今天装的5.5.2版本，发现没有elasticsearch-head组件，需要单独安装，安装过程中遇到一些错误，特此记录下来
环境
ELK-ncnode01 192.168.96.208
ELK-ncnode02 192.168.96.209
[root@ELK-ncnode02 ~]# cat /etc/redhat-release

关闭防火墙和selinux
Elasticsearch安装配置
基础环境安装（ELK-ncnode01和ELK-ncnode02同时操作）
1）下载并安装GPG Key
[root@ELK-ncnode01 ~]# rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
1
2）添加yum仓库
[root@ELK-ncnode01 ~]# vi /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

3）安装elasticsearch
[root@ELK-ncnode01 ~]# yum install elasticsearch

4）安装相关测试软件
提前先下载安装epel源：epel-release-latest-7.noarch.rpm，否则yum会报错:No Package…..
[root@ELK-ncnode01 ~]# yum install -y wget
[root@ELK-ncnode01 ~]# wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[root@ELK-ncnode01 ~]# rpm -ivh epel-release-latest-7.noarch.rpm
[root@ELK-ncnode01 ~]# yum install -y redis nginx java

配置部署（下面先进行elk-node1的配置）
1）配置修改配置文件
[root@ELK-ncnode01 ~]# vi /etc/elasticsearch/elasticsearch.yml 【将里面内容情况，配置下面内容】
cluster.name: longtel # 组名（同一个组，组名必须一致）
node.name: ELK-ncnode01 # 节点名称，建议和主机名一致
path.logs: /var/log/elasticsearch/ # 日志存放的路径
network.host: 0.0.0.0 # 网络设置
http.port: 9200 # 端口

然后通过web访问（访问的浏览器最好用google浏览器）
http://192.168.96.208:19200/
3）通过命令的方式查看数据

4）接下来安装插件，使用插件进行查看~ （下面两个插件要在ELK-ncnode01和ELK-ncnode02上都要安装）
安装elasticsearch-head插件
（请特别注意，此插件的安装和2.X的版本就不同了哦）
第一步，安装git
需要从github上面下载代码，因此先要安装git
yum -y install git
1
安装完成后，就可以直接下载代码了：
git clone git://github.com/mobz/elasticsearch-head.git
1
下载后，修改下777权限（简单粗暴），因为是独立启动head的，所以我把它放到/usr/local/下了，参考:
[root@ELK-ncnode01 local]# chmod 777 elasticsearch-head/
[root@ELK-ncnode01 local]# ls
bin elasticsearch-head etc games include lib lib64 libexec sbin share src
[root@ELK-ncnode01 local]# pwd
/usr/local
1
2
3
4
5
第二步，安装node
由于head插件本质上还是一个nodejs的工程，因此需要安装node，使用npm来安装依赖的包。（npm可以理解为maven）
去官网下载nodejs，https://nodejs.org/en/download/
下载下来的jar包是xz格式的，一般的linux可能不识别，还需要安装xz.
[root@ELK-ncnode01 local]# yum install -y xz
1
然后解压nodejs的安装包:
[root@ELK-ncnode01 local]# xz -d node-v6.11.2-linux-x64.tar.xz
[root@ELK-ncnode01 local]# ls
bin elasticsearch-head etc games include lib lib64 libexec node-v6.11.2-linux-x64.tar sbin share src
[root@ELK-ncnode01 local]# tar xvf node-v6.11.2-linux-x64.tar
1
2
3
4
解压完node的安装文件后，需要配置下环境变量,编辑/etc/profile，添加
[root@ELK-ncnode01 node-v6.11.2-linux-x64]# vi /etc/profile
# set node environment
export NODE_HOME=/usr/local/node-v6.11.2-linux-x64
export PATH=$PATH:$NODE_HOME/bin
[root@ELK-ncnode01 node-v6.11.2-linux-x64]# source /etc/profile
1
2
3
4
5
6
这个时候可以测试一下node是否生效：
[root@ELK-ncnode01 node-v6.11.2-linux-x64]# echo $NODE_HOME
/usr/local/node-v6.11.2-linux-x64
[root@ELK-ncnode01 node-v6.11.2-linux-x64]# node -v
v6.11.2
[root@ELK-ncnode01 node-v6.11.2-linux-x64]# npm -v
3.10.10
1
2
3
4
5
6
第三步，安装grunt
grunt是一个很方便的构建工具，可以进行打包压缩、测试、执行等等的工作，5.5里的head插件就是通过grunt启动的。因此需要安装一下grunt：
[root@ELK-ncnode01 elasticsearch-head]# npm install grunt
npm WARN prefer global [email protected] should be installed with -g
[email protected] /usr/local/elasticsearch-head

第四步，修改head源码
由于head的代码还是2.6版本的，直接执行有很多限制，比如无法跨机器访问。因此需要用户修改两个地方：
修改服务器监听地址
目录：/usr/local/elasticsearch-head/Gruntfile.js
connect: {
server: {
options: {
port: 9100,
hostname: '*',
base: '.',
keepalive: true
}
}
}

增加hostname属性，设置为*
修改连接地址：
目录：/usr/local/elasticsearch-head/_site/app.js
修改head的连接地址:
this.base_uri = this.config.base_uri || this.prefs.get(“app-base_uri”) || “http://localhost:9200“;
把localhost修改成你es的服务器地址，如:
this.base_uri = this.config.base_uri || this.prefs.get(“app-base_uri”) || “http://192.168.96.208:9200“;
第五步，运行head
首先开启5.5 ES。
然后在head目录中，执行npm install 下载以来的包：
npm install
此处会报错如下
解决方法
[root@ELK-ncnode01 elasticsearch-head]# npm install [email protected] --ignore-script
[email protected] /usr/local/elasticsearch-head

执行如下
[root@ELK-ncnode01 elasticsearch-head]# npm install --no-optional
npm WARN [email protected] license should be a valid SPDX license expression

还有一个WARN，打开elasticsearch-head目录下的package.json文件，找到license位置，修改为上面这个网站上存在Identifier，就可以了。如图所示，把原来的Apache内容修改为Apache-2.0。具体修改后的内容参考官网上的Identifier数值（防止后续更新，授之于渔了）。
[root@ELK-ncnode01 elasticsearch-head]# vi package.json
"author": "",
"license": "Apache-2.0",
"gitHead": "0c2ac0b5723b493e4454baa7398f386ecb829412",
"readmeFilename": "README.textile",

再次执行
[root@ELK-ncnode01 elasticsearch-head]# npm install --no-optional
[root@ELK-ncnode01 elasticsearch-head]#

没有一点毛病了
最后，启动nodejs
grunt server
访问:target:9100
这个时候，访问http://192.168.96.208:9100就可以访问head插件了.
访问http://192.168.96.209:9100也可以
ELK-ncnode02也要做全局的配置
[root@ELK-ncnode02 _site]# vi /etc/elasticsearch/elasticsearch.yml
cluster.name: longtel
node.name: ELK-ncnode02
path.logs: /var/log/elasticsearch/
network.host: 0.0.0.0
