安装elasticsearch-head

步骤1：准备

1. 安装docker

安装 docker 参考：【Centos 8】【Centos 7】安装 docker

2. 搜索可以使用的镜像。

shell> docker search mobz/elasticsearch-head
NAME                      DESCRIPTION                                     STARS     OFFICIAL   AUTOMATED
mobz/elasticsearch-head   elasticsearch-head front-end and standalone …   95                   

3. 也可从docker hub上搜索镜像。

docker hub，docker hub-stage。

4. 选择合适的redis镜像。

版本	拉取命令
5	docker pull mobz/elasticsearch-head:5

步骤2：拉取elasticsearch-head镜像

查看已拉取的镜像

shell> docker images
REPOSITORY                TAG       IMAGE ID       CREATED        SIZE

步骤3：创建容器

创建容器方式1：快速创建容器

shell> docker create --name elasticsearch-head1 -p 9100:9100 mobz/elasticsearch-head:5

步骤4：启动容器

shell> docker start elasticsearch-head1

步骤5：检查是否安装成功

浏览器打开 http://localhost:9100, 如果出现以下界面就是安装成功：

ElasticSearch-head 配置

工作目录/WorkingDir

"WorkingDir": "/usr/src/app" 

ElasticSearch-head 容器设置

容器随 docker 自动启动

设置容器的重启策略

shell> docker update --restart=always elasticsearch-head1

• 每次docker启动时，容器也会自动启动

容器设置IP

向网络中添加容器

shell> docker network connect --ip 172.19.0.2  mynetwork elasticsearch-head1 

• docket ip : 172.19.0.2

其它

打开 elasticsearch-head

• http://localhost:9100
• http://localhost:9100/?base_uri=http://127.0.0.1:9200
• http://localhost:9100/?base_uri=http://127.0.0.1:9200&auth_user=elastic&auth_password=changeme
• http://localhost:9100/?base_uri=http%3A%2F%2F127.0.0.1:9200&auth_user=elastic&auth_password=changeme

登录容器

shell> docker exec -it elasticsearch-head1 /bin/bash

从 docker 向宿主拷贝WorkingDir目录

shell> docker cp elasticsearch-head1:/usr/src/app ~/

从宿主向 docker 拷贝文件

shell> docker cp ~/app/_site/vendor.js  elasticsearch-head1:/usr/src/app/_site

406 错误

请求 ElasticSearch API 遇到 406 错误 ：

{"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}

原因：elasticsearch 增加了内容类型检查，推荐使用Content-Type: application/json

解决方法：

1. 从 docker 容器向宿主拷贝WorkingDir目录
2. 修改_site/vendor.js。编辑vendor.js 共有两处

修改 6886行：
contentType: "application/x-www-form-urlencoded
改成
contentType: "application/json;charset=UTF-8"

修改 7573行： 
var inspectData = s.contentType === "application/x-www-form-urlencoded" &&
改成
var inspectData = s.contentType === "application/json;charset=UTF-8" &&

3. 将 vendor.js 拷贝到docker容器
4. 重启容器
