如何快速运行一个elasticsearch, 当然是用Docker来跑了. 不需要复杂的编译安装,只需要在linux下面,执行一个命令,就可以让elasticsearch跑起来.

准备

Linux x64 系统, 如 centos 7和 ubuntu 18.04

15GB 或更多磁盘空间

1GB或更多内存

网络连接

根据docker 官方教程安装好docker,并已经启动docker

开始

开启一个命令行shell,执行命令启动 elasticsearch

docker run -d --restart=always --name es -p 9200:9200 
 -p 9300:9300 elasticsearch:6.7.0

等待片刻,然后检查 日志是否正常

docker logs -f es 

如果没有错误,那么你可以开始用curl测试

$ curl -v http://127.0.0.1:9200/
* Trying 127.0.0.1:9200...
* TCP_NODELAY set
* Connected to 127.0.0.1 (127.0.0.1) port 9200 (#0)
> GET / HTTP/1.1
> Host: 127.0.0.1:9200
> User-Agent: curl/7.66.0
> Accept: */*
> 
* Mark bundle as not supporting multiuse
< HTTP/1.1 200 OK
< content-type: Application/json; charset=UTF-8
< content-length: 496

到这里,你的elasticsearch就跑起来了,可以开始写程序查询elasticsearch了
