问题
Due to the restrictions, I was not allowed to install any packages from internet. So, This command is not useful for me inorder to install search-guard.
bin/elasticsearch-plugin install -b com.floragunn:search-guard-ssl:<version>
However, I am able to install Search Guard successfully on a different network by running the above command.
Because of this reason, I tried installing Search Guard from tar.gz or zip file by the below command as per documentation.
/usr/share/elasticsearch# bin/elasticsearch-plugin install file:///home/xxxx/xxxx/search-guard-5-5.2.0-10-sgadmin-standalone.zip
This one is failing with the below error.
-> Downloading file:///home/xxx/xxxx/search-guard-5-5.2.0-10- sgadmin-standalone.zip
[=================================================] 100%
ERROR: `elasticsearch` directory is missing in the plugin zip
I downloaded zip/tar.gz from this maven repository of search gaurd.
Is anyone also facing the same issue. If not, kindly help in solving this one.
