- 安裝es5.3.2

解壓后
chown -R elasticsearch: elasticsearch elasticsearch-2.3.4/
su elasticsearch
./elasticsearch -d 后臺啟動

curl -XGET 'localhost:9200'
如果要重啟貌嫡，ps -aux|grep elastic，找到進程kill掉再重啟 - 安裝node

yum -y install xz
xz -d node-v6.10.2-linux-x64.tar.xz
tar -xvf node-v6.10.2-linux-x64.tar
mv到/usr/local/node下面
vi /etc/profile
NODE_HOME=/usr/local/node
PATH=$PATH:$NODE_HOME/bin
export JAVA_HOME JRE_HOME CATALINA_HOME NODE_HOME PATH CLASSPATH
npm -g install grunt-cli

wget http://xbib.org/repository/org/xbib/elasticsearch/importer/elasticsearch-jdbc/2.3.4.0/elasticsearch-jdbc-2.3.4.0-dist.zip
安裝配置后堤撵，要切換到root執(zhí)行./import.shAPI
- delete
curl -XDELETE 'http://localhost:9200/twitter/tweet/1'
curl -XDELETE 'http://localhost:9200/ymm'

http://www.cnblogs.com/woxpp/p/6061073.html - 9200缺省限制為本機訪問，安裝成功后在本機curl -XGET 'localhost:9200'是可以的，但在其他機器通過ip訪問不行夺脾，這里需要修改elasticsearch.yml文件蚀乔，增加network.bind_host: 0.0.0.0，并重啟es
- elasticsearch=head無法連接9200出牧，處理方法參考http://www.cnblogs.com/zklidd/p/6433123.html
vi elasticsearch.yml 添加
http.cors.enabled: true
http.cors.allow-origin: "*"
