Info

The command shown above will add a service named solr2 running on port 8984 using /var/solr2 for writable (aka "live") files; the second server will still be owned and run by the solr user and will use the Solr distribution files in /opt. After installing the solr2 service, verify it works correctly by doing: $ sudo service solr2 restart $ sudo service solr2 status Securing Solr When planning how to secure Solr, you should consider which of the available features or approaches are right for you. Authentication or authorization of users using: Kerberos Authentication Plugin Basic Authentication Plugin Rule-Based Authorization Plugin Custom authentication or authorization plugin Enabling SSL If using SolrCloud, ZooKeeper Access Control Authentication and Authorization Plugins Solr has security frameworks for supporting authentication and authorization of users. This allows for verifying a user's identity and for restricting access to resources in a Solr cluster. Solr includes plugins to support Basic authentication, Kerberos, and rule-based authorization of users. Additional plugins can be developed using the authentication and authorization frameworks described below. The plugin implementation will dictate if the plugin can be used with Solr running in SolrCloud mode only or also if running in standalone mode. If the plugin supports SolrCloud only, a security.json file must be created and uploaded to ZooKeeper before it can be used. If the plugin also supports standalone mode, a system property -DauthenticationPlugin= can be used instead of creating and managing s ecurity.json in ZooKeeper. Here is a list of the available plugins and the approach supported: Basic authentication: SolrCloud only. Kerberos authentication: SolrCloud or standalone mode. Rule-based authorization: SolrCloud only. The following section describes how to enable plugins with security.json in ZooKeeper when using Solr in SolrCloud mode. Enable Plugins with security.json All of the information required to initialize either type of security plugin is stored in a /security.json file in ZooKeeper. This file contains 2 sections, one each for authentication and authorization. Apache Solr Reference Guide 6.0 510
security.json { } "authentication" : { "class": "class.that.implements.authentication" }, "authorization": { "class": "class.that.implements.authorization" } The /security.json file needs to be in ZooKeeper before a Solr instance comes up so Solr starts with the security plugin enabled. See the section Adding security.json to Zookeeper below for information on how to do this. Depending on the plugin(s) in use, other information will be stored in security.json such as user information or rules to create roles and permissions. This information is added through the APIs for each plugin provided by Solr, or, in the case of a custom plugin, the approach designed by you. Here is a more detailed security.json example. In this, the Basic authentication and rule-based authorization plugins are enabled, and some data has been added: { "authentication":{ "class":"solr.BasicAuthPlugin", "credentials":{"solr":"IV0EHq1OnNrj6gvRCwvFwTrZ1+z1oBbnQdiVC3otuq0= Ndd7LKvVBAaZIF0QAVi1ekCfAJXr1GGfLtRUXhgrF8c="} }, "authorization":{ "class":"solr.RuleBasedAuthorizationPlugin", "permissions":[{"name":"security-edit", "role":"admin"}] "user-role":{"solr":"admin"} }} Adding security.json to ZooKeeper While configuring Solr to use an authentication or authorization plugin, you will need to upload a security.jso n file to ZooKeeper as in the example below. > server/scripts/cloud-scripts/zkcli.sh -zkhost localhost:2181 -cmd put /security.json '{"authentication": {"class": "org.apache.solr.security.KerberosPlugin"}}' Note that this example defines the KerberosPlugin for authentication. You will want to modify this section as appropriate for the plugin you are using. This example also defines security.json on the command line, but you can also define a file locally and upload it to ZooKeeper. Depending on the authentication and authorization plugin that you use, you may have user information stored in security.json. If so, we highly recommend that you implement access control in your ZooKeeper nodes. Information about how to enable this is available in the section ZooKeeper Access Control.
