（3）docker安装elasticsearch-2.4.5

1、先安装elasticsearch-head

从git上下载源码，把_site部署到容器中运行

下载地址：https://github.com/mobz/elasticsearch-head

访问： http://ip:9100/

2、docker安装es-2.4.5

拉取镜像：

[root@starseaing9228 ~]# docker pull elasticsearch:2.4.5

[root@starseaing9228 ~]# vi /usr/local/elasticsearch245/conf/elasticsearch.yml

elasticsearch.yml内容如下：

# ======================== Elasticsearch Configuration =========================
cluster.name: my-test
node.name: node-test
#path.data: D:/es-data-test/data
#path.logs: D:/es-data-test/logs

# 如果要开启远程访问需要设置为0.0.0.0，意思是允许任意IP连接
# network.host: 127.0.0.1
network.host: 0.0.0.0
http.port: 9200

#后面的两个配置项目需要添加，用于elasticsearch head连接es。
# http.cors.enabled true 如果启用了 HTTP 端口，那么此属性会指定是否允许跨源 REST 请求。
# http.cors.allowed.origin localhost 如果 http.cors.enabled 的值为 true，那么该属性会指定允许 REST 请求来自何处。
http.cors.enabled: true
http.cors.allow-origin: "*"

3.运行elasticsearch

目录挂载：
配置文件：/usr/local/elasticsearch245/conf/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
数据目录：/usr/local/elasticsearch245/data/:/usr/share/elasticsearch/data

docker运行命令为：

docker run --name elasticsearch245 -p 9200:9200 -p 9300:9300 -v /usr/local/elasticsearch245/conf/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /usr/local/elasticsearch245/data/:/usr/share/elasticsearch/data -d elasticsearch:2.4.5

[root@starseaing9228 ~]# docker run --name elasticsearch245 -p 9200:9200 -p 9300:9300 -v /usr/local/elasticsearch245/conf/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /usr/local/elasticsearch245/data/:/usr/share/elasticsearch/data -d elasticsearch:2.4.5
