如何在centos 6.5 下利用docker里部署elasticsearch，
安装docker[root@localhost ~]# uname -r
2.6.32-431.el6.x86_64
[root@localhost ~]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
注意其他的源可能导致你的内核和docker的版本不一致，需要升级内核至3.x。
安装：
[root@localhost ~]# rpm -ivh http://dl.Fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

yum install device-mapper-event-libs
下载镜像
docker pull elasticsearch:2
mkdir -p /es/{data01,data02,logs,elasticsearch}
chown elasticsearch.elasticsearch -R /es
docker cp es/ es:/etc/elasticsearch/ docker里配置cp到主机，之后修改配置文件
docker exec -it es bash
[root@bogon ~]# cd /es/elasticsearch/
[root@bogon elasticsearch]# ls
elasticsearch.yml logging.yml scripts
[root@bogon elasticsearch]#
chmod 777 -R /es/
由于本机还有一个ES，怕端口冲突，因此端口做了下更改如下
[root@bogon elasticsearch]# cat elasticsearch.yml
network.host: 0.0.0.0
path.data: /data01,/data02
path.logs: /logs
http.port: 9292
http.cors.enabled: true
http.cors.allow-origin: "*"
discovery.zen.ping.unicast.hosts: ["10.80.1.11","10.80.1.12","10.80.1.13","10.80.1.14","10.80.1.15"]
transport.tcp.port: 9393
启动ES
docker run --net=host -d -p 9292:9292 -p 9393:9393 --name es -v /es/elasticsearch:/usr/share/elasticsearch/config -v /es/data01:/data01 -v /es/data02:/data02 -v /es/logs:/logs -u root b4c7b5ea84aa
