文章标签 elk需要对外开放那些端口 elasticsearch nginx vim 文章分类 运维

1.下载相关软件及插件
http://www.elastic.co --- > 产品 --- > elasticsearch、logstash、kibana、filebeat等

可以下载 tar、zip、rpm等多种格式，具体想用哪个需要按自己的需求选择

或
wget https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.3.4/elasticsearch-2.3.4.tar.gz
wget https://download.elastic.co/logstash/logstash/logstash-2.3.4.tar.gz
wget https://download.elastic.co/kibana/kibana/kibana-4.5.3-linux-x64.tar.gz
wget http://download.oracle.com/otn-pub/java/jdk/8u45-b14/jdk-8u45-linux-x64.tar.gz

2.配置安装环境
jdk 1.8及以上版本，可使用oracle jdk 也可使用 open jdk （视情况自己选择）

#系统优化
vim /etc/security/limits.conf #这个初始优化的时候一般都会做好
* soft nofile 1024000
* hard nofile 1024000
# End of file
# vi /etc/sysctl.conf
vm.max_map_count = 655360
# sysctl -p

#解压 elasticsearch
cd /opt/elk/
tar -xvf elasticsearch-6.2.4.tar.gz
mv elasticsearch-6.2.4.tar.gz elasticsearch
cd elasticsearch/config
#编辑配置文件
vim elasticsearch.yml
#写一下几项

#安装head插件
ElasticSearch-Head 是一个与Elastic集群（Cluster）相交互的Web前台。
ES-Head的主要作用：
它展现ES集群的拓扑结构，并且可以通过它来进行索引（Index）和节点（Node）级别的操作
它提供一组针对集群的查询API，并将结果以json和表格形式返回
它提供一些快捷菜单，用以展现集群的各种状态
5.x以后的版本安装Head插件比较麻烦，不能像2.x的时候一条#elasticsearch/bin/plugin install mobz/elasticsearch-head #一波搞定

#安装ndoe.js
#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），官网nodejs，https://nodejs.org/en/download/

#wget https://nodejs.org/dist/v8.9.1/node-v8.9.1.tar.gz #新版要编译时间太长了用旧版本吧
# tar zxf node-v8.9.1.tar.gz
#cd node-v8.9.1
#./configure --prefix=/usr/local/node-8.9.1 && make -j 8 && make install #安装时间比较长，没办法，Centos7的系统要最新版本的nodejs。

# ln -s /usr/local/node-v6.10.2-linux-x64 /usr/local/node
# vim /etc/profile

下载插件包
# yum install git -y
# git clone https://github.com/mobz/elasticsearch-head.git #下载head插件文件
# cd elasticsearch-head/
# npm install -g grunt --registry=https://registry.npm.taobao.org
#使用国内淘宝源安装grunt，grunt是基于Node.js的项目构建工具，可以进行打包压缩、测试、执行等等的工作，head插件就是通过grunt启动

修改配置文件
# mkdir /home/elk/plugin

# cp -rf /opt/elasticsearch-head /home/elk/plugin/head
# chown -R elk:elk /home/elk
$ vim /home/elk/plugin/head/Gruntfile.js

$ cd /home/elk/plugin/head/ #一定要进入此目录下启动命令啊
$ grunt server #服务启动了

解决使用 Head 插件连接不上集群：
$ vim elasticsearch/config/elasticsearch.yml #加下面两句话
Bashhttp.cors.enabled: true
http.cors.allow-origin: "*"
$ /home/elk/elasticsearch/bin/elasticsearch -d #重新启动es服务
$ pwd
/home/elk/plugin/head$ nohup grunt server

#需要创建 elsearch 用户，因为elasticsearch么人是能用root用户启动
useradd elsearch
su elsearch
#后台启动
