yum install -y nodejs

npm install -g cnpm --registry=https://registry.npm.taobao.org

###如果抱错   npm: relocation error: npm: symbol SSL_set_cert_cb, version libssl.so.10 not defined in file libssl.so.10 with link time reference

##就升级openssl

yum update openssl

npm install -g grunt

wget https://github.com/mobz/elasticsearch-head/archive/master.zip

unzip master.zip

###进入elasticsearch-head-master目录，执行下面命令

npm install

vi config/elasticsearch.yml

# 增加新的参数，这样head插件可以访问es。设置参数的时候:后面要有空格

http.cors.enabled: true

http.cors.allow-origin: "*"

 vim Gruntfile.js 

###到connect：server，添加hostname一项
