一、elasticsearch安装配置
1.官网下载源码包
https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.0.0.tar.gz
2.解压安装
useradd elasticsearch
tar xf elasticsearch-5.0.0.tar.gz -C /usr/local
cd /usr/local
ln -sv elasticsearch-5.0.0 elasticsearch
mkdir -pv /data/elasticsearch/{data,logs}
chown -R elasticsearch.elasticsearch /data/elasticsearch
3.修改配置文件
cat /usr/local/elasticsearch/config/elasticsearch.yml
path.data:/data/elasticsearch/data
path.logs:/data/elasticsearch/logs
network.host:192.168.1.12
http.cors.enabled:true
http.cors.allow-origin:"*"
4.修改系统参数
cat /etc/security/limits.conf
* soft nproc 65536
* hard nproc 65536
* soft nofile 65536
* hard nofile 65536
cat /etc/sysctl.conf
vm.max_map_count= 262144
sysctl -p
5.启动服务
su - elasticsearch -c "/usr/local/elasticsearch/bin/elasticsearch &"
浏览器访问：http://192.168.1.12:9200/
二、head插件的安装
在5.0版本中不支持直接安装head插件，需要启动一个服务
1.下载插件安装
git clone git://github.com/mobz/elasticsearch-head.git
cd elasticsearch-head
npm install
在elasticsearch-head目录下node_modules/grunt下如果没有grunt二进制程序，需要执行
cd elasticsearch-head
npm install grunt --save
2.修改配置
修改elasticsearch-head下Gruntfile.js文件，默认监听在127.0.0.1下9200端口
3.启动服务
/usr/local/elasticsearch-head/node_modules/grunt/bin/gruntserver
浏览器访问 http://192.168.1.12:9100/
