Manual install of Elasticsearch plugins

Question

Because my Elasticsearch server is behind a proxy, I can't directly install plugins using the command under bin.

So I tried uncompressing some of them in the plugins directory, with no luck.

Specifically I tried this https://github.com/jprante/elasticsearch-knapsack and I can't get it to work.

Any help?

Answer 1

Typically uncompressing the plugin file into plugins directory should work as long as file access rights are not messed up. To verify that plugin is installed correctly check that elasticsearch home directory contains directory called plugins/knapsack and that this directory contains two files: commons-compress-1.4.1.jar and elasticsearch-knapsack-2.1.2.jar

You can also download plugin zip file to a temporary location and then install it by specifying path to it using --url parameter:

bin/plugin --install knapsack --url file:///Full/Path/To/elasticsearch-knapsack-2.1.2.zip

See Plugins documentation for more information.

Answer 2

I have used the following to install the plugin behind the firewall:

bin/plugin -DproxyHost=myproxy.proxy.com -DproxyPort=80 --install lmenezes/elasticsearch-kopf
