问题
In order to upgrade our 1.5.2 elasticsearch to 2.x, I have successfully installed elasticsearch migration plugin v1.18, but when linking to http://localhost:9200/_plugin/migration/ I get a blank page.
Also the next command gives me nothing:
~/bin/elasticsearch-1.5.2$ curl -XGET http://localhost:9200/_plugin/migration/
What am I missing?
回答1:
Did you install the plugin as root?
Check the permissions of /usr/share/elasticsearch/plugins/migration. Your default umask may prevent the elasticsearch user to read the contents.
This fixed it for me:
chown -R elasticsearch:elasticsearch /usr/share/elasticsearch/plugins
