Mac 安装Elasticsearch 5.0

Install Elasticsearch 5.0

1. Download .zip/.tar.gz 下载地址
2. tar -xzf elasticsearch-5.0.0.tar.gz
3. 修改配置文件(xx/config/elasticsearch.yml)：
   
   • path.data:/data/elasticsearch/data #数据目录
   • path.logs:/data/elasticsearch/logs #日志目录
   • network.host:x.x.x.x
   • http.cors.enabled:true #这个参数设置head插件连接es集群
   • http.cors.allow-origin:”*” #同上（如果不设置最后这两个参数head插件连接不到es集群）
4. 启动es,nohup bin/elasticsearch > logs/xxx.log 2>&1 &

Install elasticsearch-head（es5.0不支持site plugin,所以需要单独安装head插件）

1. elasticsearch-head
2. enable cors by adding http.cors.enabled: true in elasticsearch configuration. Don’t forget to also set
   http.cors.allow-origin because no origin allowed by default. http.cors.allow-origin: “*” is valid value, however it’s considered as a security risk as your cluster is open to cross origin from anywhere. Check Elasticsearch documentation on this parameter
3. git clone git://github.com/mobz/elasticsearch-head.git
4. cd elasticsearch-head
5. npm install
6. grunt server（如果没有grunt，执行npm install -g grunt-cli安装）
7. open http://localhost:9100/
