How to disable solr admin page

问题

For production, it feels unsafe to have a solr admin which even doesn't ask login credentials. How can I disable the solr admin page which comes by default? I simply want my webapp to use Solr for search term indexing.

回答1:

I highly suggest keeping the admin page for debugging purposes. It has saved me in numerous cases. There are ways to restrict it to HTTP-authenticated users only: http://wiki.apache.org/solr/SolrSecurity#Jetty_example . You may have to unzip and re-zip your webapp.

However if you still want to disable the entire admin section, you can comment out the admin requestHandler in ${SOLR_HOME}/project/solr/conf/solrconfig.xml .

回答2:

You could protect your admin page with a password just by adding a security constraint to the Solr web application.

Snippet for Solr 3.6:

  <security-constraint>
    <!-- This protects your admin interface and grants access to role Solr-Admin -->
    <web-resource-collection>
    <web-resource-name>Solr admin</web-resource-name>
      <!--url-pattern>/admin/*</url-pattern-->
      <url-pattern>/evu/admin/*</url-pattern>
      <url-pattern>/webcrawl/admin/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
      <role-name>Solr-Admin</role-name>
    </auth-constraint>
    <user-data-constraint>
      <transport-guarantee>CONFIDENTIAL</transport-guarantee>
    </user-data-constraint>
  </security-constraint>

  <security-constraint>
    <!-- This protects your admin interface and grants access to roles Solr-Admin and Solr-Updater -->
    <web-resource-collection>
      <web-resource-name>Solr Update</web-resource-name>
      <url-pattern>/update/*</url-pattern>
      <url-pattern>/evu/update/*</url-pattern>
      <url-pattern>/webcrawl/update/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
      <role-name>Solr-Admin</role-name>
      <role-name>Solr-Update</role-name>
    </auth-constraint>
    <user-data-constraint>
      <transport-guarantee>CONFIDENTIAL</transport-guarantee>
    </user-data-constraint>
  </security-constraint>

  <security-constraint>
    <!-- This one is necessary to show the image on the Solr start page -->
    <web-resource-collection>
      <web-resource-name>Solr Admin images</web-resource-name>
      <url-pattern>*.png</url-pattern>
    </web-resource-collection>
    <auth-contraint>
      <role-name>*</role-name>
    </auth-contraint>
  </security-constraint>

  <security-role>
    <description>The role that is required to administer Solr</description>
    <role-name>Solr-Admin</role-name>
  </security-role>
  <security-role>
    <description>The role that is required to update the Solr index</description>
    <role-name>Solr-Update</role-name>
  </security-role>

  <login-config>
    <auth-method>BASIC</auth-method>
    <realm-name>Solr</realm-name>
  </login-config>
</web-app>

In Solr 4 you have to protect the following resources for the admin interface:

/admin/*
/admin.html

sudo vim /opt/solr-4.8.1/example/etc/jetty.xml change

  <!-- This connector is currently being used for Solr because it
          showed better performance than nio.SelectChannelConnector
          for typical Solr requests.  -->
    <Call name="addConnector">
      <Arg>
          <New class="org.eclipse.jetty.server.bio.SocketConnector">
            <Set name="host">0.0.0.0</Set>
            <Set name="port"><SystemProperty name="jetty.port" default="8983"/></Set>
            <Set name="maxIdleTime">50000</Set>
            <Set name="lowResourceMaxIdleTime">1500</Set>
            <Set name="statsOn">false</Set>
          </New>
      </Arg>
    </Call>

then sudo service solrd restart

The most easy way:

iptables -A INPUT -p tcp --dport 8983 -j DROP

iptables -A INPUT -p tcp -s 127.0.0.1 --dport 8983 -j ACCEPT

with this order!
