 docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9200:9200 -p 9300:9300 -v /opt/es-cluster/config/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /opt/es-cluster/data1:/usr/share/elasticsearch/data --name ES01 docker.elastic.co/elasticsearch/elasticsearch:6.2.4

/------------------------------------------------------------------------

这里需要特别指出的是要在elasticsearhc.yml中添加如下配置：

 http.cors.enabled: true
 http.cors.allow-origin: "*"
 http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type
http.cors.allow-headers官网给的配置是：http.cors.allow-headers: Authorization 亲测不能正常访问，不明白为什么

重启ES就可以通过：http://192.168.1.215:9100/?auth_user=elastic&auth_password=passwd 访问head插件了

elasticsearch head + xpack 用户名密码访问

修改配置文件elasticsearch.yml，增加
http.cors.allow-headers: Authorization(不起作用，换成下面一行)

 http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

访问head时，url如下所示：
http://192.168.100.100:9100/?auth_user=elastic&auth_password=changeme

/_-------------------------------------------------

elasticsearch-head安装

3.1 拉取镜像
docker pull yanliangzhong/elasticsearch-head
3.2 运行容器
docker run -d –name es_admin -p 9100:9100 yanliangzhong/elasticsearch-head

3.3 配置跨域及用户名

/--------------------------------------------------------------

x-pack 修改密码

进入docker elasticsearch容器中

cd /data/elasticsearch-6.2.4/bin/x-pack

bin/elasticsearch-setup-passwords interactive

设置elastic/kibana/logstack的密码；

修改密码

• curl -H "Content-Type:application/json" -XPOST -u elastic 'http://127.0.0.1:9200/_xpack/security/user/elastic/_password' -d '{ "password" : "123456" }'

修改kibana配置文件,config下的kibana.yml,添加如下内容

1. elasticsearch.username: "elastic"

2. elasticsearch.password: "123456"

成功后显示
