Elastic Search环境初始化

1. 安装

确认开发机器上已经安装了Docker环境，并保证Docker Engine已经运行起来。

# script/shell/ox-es.sh
# 必须进入到shell目录中执行，文件路径使用了相对路径
cd script/shell
./ox-es.sh

如果是「第一次」运行该脚本，需要等待Docker下载相关镜像信息：

./ox-es.sh                                                                                                                                                                                          lang@LangYus-MacBook-Pro

2. 脚本内容

ox-es.sh的脚本内容如下

#!/usr/bin/env bash
img_name="es"
container_name=ox_${img_name}

docker stop ${container_name}
docker rm ${container_name}
docker rmi ${img_name}:latest

docker build -t ${img_name}:latest -f ox-es .
docker run \
  -p 9200:9200 \
  -p 9300:9300 \
  -e "discovery.type=single-node" \
  --name ${container_name} ${img_name}

ox-es的文件内容如下（Dockerfile）

FROM elasticsearch:2.4.6

由于jhipster的部分限制，es的版本最好和当前使用版本匹配：2.4.6，如果使用高版本或者其他版本有可能会运行不了，启动好ES过后，直接在浏览器中打开：http://localhost:9200/ 地址，就可以看到下边的信息，证明ES已经启动好了：
