Setting up basic authentication Solr 5.3.1 for dummies - apache

Question

OK, so I'm not a server guru, but I need to figure out how to set up authentication for our solr server admin page. I'm trying to follow the steps outlined here:
https://lucidworks.com/2015/08/17/securing-solr-basic-auth-permission-rules/
I can't even complete the first step, upload the JSON file. I created the JSON file, but when I go to upload it, I get a "command not found" error when trying to run zkcli.sh. Do I need to set something up with Zookeeper first to get this to run? What should I check?
EDIT: I followed some tutorials online and did the following:
1) set jetty-http.xml to localhost (changing the host to 127.0.0.1) by adding the line:
<Set name="Host"><SystemProperty name="jetty.host" default="127.0.0.1"/></Set>
2) I also added the following to the apache config file (obv changing to correct path in the path to htpasswd):
<Location /solr >
AuthName "Secure Area"
AuthType Basic
AuthUserFile /path/to/htpasswd/.htpasswd require valid-user
</Location>
ProxyPass /solr http://localhost:8983/solr
ProxyPassReverse /solr http://localhost:8983/solr
3) I set up a password via htpasswd.
4) I restarted the server. I refreshed the solr page and nothing; it's a broken link.
What am I doing wrong?
(Unfortunately every time I do that the solr core also disappears and refuses to load. That's another issue though, which I thought was related to permissions but doesn't seem to be...)

You can follow these steps to get the basic authentication work in solr.
Assuming you have ubuntu OS and installled the server using the install script.
Step1. sudo vi /opt/solr/server/etc/jetty.xml
Add the following code towards the end of the file before the "" tag.
<Call name="addBean">
<Arg>
<New class="org.eclipse.jetty.security.HashLoginService">
<Set name="name">Test Realm</Set>
<Set name="config"><SystemProperty name="jetty.home" default="."/>/etc/realm.properties</Set>
<Set name="refreshInterval">0</Set>
</New>
</Arg>
</Call>
Step2. sudo vi /opt/solr/server/etc/webdefault.xml
Add the following code towards the end of the file before the "" tag.
<security-constraint>
<web-resource-collection>
<web-resource-name>Solr authenticated application</web-resource-name>
<url-pattern>/</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>core1-role</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>Test Realm</realm-name>
</login-config>
Step3. Create the file "/opt/solr/server/etc/realm.properties" with the following contents:
USERNAME: PASSWORD,core1-role
The username and password is stored in the following file /opt/solr/server/etc/realm.properties
