ES插件elasticsearch-mapper-attachments 2.3.4及各个版本正确下载地址

ES版本更新那么快，文档链接你也倒是跟上啊，

插件zip包下载，都是error link。。。难不成是我网络原因？

下载zip页面报错信息：

官方给的什么链接啊，都是失效的：

[失效] https://download.elasticsearch.org/elasticsearch/elasticsearch-mapper-attachments/elasticsearch-mapper-attachments-2.3.4.zip

[失效] https://artifacts.elastic.co/downloads/elasticsearch-plugins/ingest-attachment/ingest-attachment-5.2.0.zip

找了好久，终于找到elasticsearch-mapper-attachments-2.3.4.zip的正确下载链接，其他版本的只需把2.3.4替换成对应版本即可：

[可用] https://download.elastic.co/elasticsearch/release/org/elasticsearch/plugin/mapper-attachments/2.3.4/mapper-attachments-2.3.4.zip

然后，输入下面的命令离线安装。

bin/plugin install file:///path/to/mapper-attachments-2.3.4.zip

--------------------------------------------------------------------------------------------------

后来发现有一种更快捷的方式，就是直接输入:-)

bin/plugin install mapper-attachments

然后后面就回出现：

-> Installing mapper-attachments...
Trying https://download.elastic.co/elasticsearch/release/org/elasticsearch/plugin/mapper-attachments/2.3.4/mapper-attachments-2.3.4.zip ...
ERROR: failed to download out of all possible locations..., use --verbose to get detailed information

把那个链接直接下载就行
