Hi there, first time to try to install shield to elasticsearch, I used elasticsearch RPM to install elasticsearch, and then I install shield by this page steps ([https://www.elastic.co/guide/en/shield/current/installing-shield.html#offline-install](https://www.elastic.co/guide/en/shield/current/installing-shield.html#offline-install)) but when I'd restart elasticsearch, I found errors in logs, the content shown, ``` [2015-08-03 15:07:09,061][INFO][node] [elknode] version[1.6.0], pid[31829], build[cdd3ac4/2015-06-09T13:36:34Z] [2015-08-03 15:07:09,062][INFO][node] [elknode] initializing ...

Yes you need the license plugin as well as the Shield one, you can get that with `wget https://download.elastic.co/elasticsearch/license/license-1.0.0.zip`. Shield does need to be installed on _all_ nodes in the cluster, this includes master, data and client nodes. ---

Hi Mark, Thanks very much, it works fine So the access control tools like Shield, which is production level tool? Only can be used 30 days in trial edition? if it expired later and I didn't update the license, does not it work normally or shall I remove Shield plugin? Jason ---

The trial is only for 30 days, yes. If it expires then we restrict access to certain APIs but you can still access your data. ---

Hi Jason, To be clear, we outline the full behavior in our docs here [1]. While we do restrict access to the health and stats APIs if your Shield license expires, the search and indexing APIs continue to operate and we do not disable your security settings. If you need a trial license extension, just send an email to info@elastic.co and we can send you one. Thanks, Steve [1] [https://www.elastic.co/guide/en/shield/current/license-management.html#license-expiration](https://www.elastic.co/guide/en/shield/current/license-management.html#license-expiration) ---

Hi Steve, After the license expired, $curl -u es\_admin:iiiiii '[http://localhost:9200/\_cat/indices?v](http://localhost:9200/_cat/indices?v)' {"error":"LicenseExpiredException[license expired for feature [shield]]","status":401} as you said, the indexing APIs continue to operate, but it seems to doesn't work?? How should I keep my elasticsearch work normally if I don't want to extend license? Jason ---

You either need to subscribe to one of our support offerings to get a full license for Shield, or uninstall it from your nodes. ---

`sudo bin/plugin -r shield sudo bin/plugin -r license` I'll make a note to get that documented 🙂 ---
