Abiquo Apache Frontend

This guide will show you how to configure an Apache as a front door with SSL protection for Abiquo. The communication between Apache and Tomcat is done with the AJP Connector to improve performance.

...

Install Apache with mod_ssl

...

Code Block
# yum install -y httpd mod_ssl openssl

Generate keys

Generate private key:

...

class	verysmallcode

...

Generate CSR:

...

Code Block
# openssl req -new -key ca.key -out ca.csr

Generate self signed key:

Div

class	verysmallcode

Code Block

# openssl x509 -req -days 365 -in ca.csr -signkey ca.key -out ca.crt

Move files to the correct location:

div

class	verysmallcode

Code Block

# mv ca.crt /etc/pki/tls/certs
# mv ca.key /etc/pki/tls/private/ca.key
# mv ca.csr /etc/pki/tls/private/ca.csr

Configure Apache

Move default configurations

#

Div

class	verysmallcode

Code Block

# mv /etc/httpd/conf.d/ssl.conf /etc/httpd/conf.d/ssl.conf.bck
# mv /etc/httpd/conf.d/welcome.conf /etc/httpd/conf.d/welcome.conf.bck

Configure SSL

Edit a new /etc/httpd/conf.d/ssl.conf with the following parameters:

...

Code Block

LoadModule ssl_module modules/mod_ssl.so
Listen 443
AddType application/x-x509-ca-cert .crt
AddType application/x-pkcs7-crl    .crl
SSLPassPhraseDialog  builtin
SSLSessionCache         shmcb:/var/cache/mod_ssl/scache(512000)
SSLSessionCacheTimeout  300
SSLMutex default
SSLRandomSeed startup file:/dev/urandom  256
SSLRandomSeed connect builtin
SSLCryptoDevice builtin

Configure AJP Proxy

Info
You can use mod_rewrite to define a different location URI for the client. For example, <Location /management>

Edit /etc/httpd/conf.d/proxy_ajp.conf and add these lines:

...

verysmallcode

Code Block

<VirtualHost *:80>
    RewriteEngine On
    RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [L,R=301]
</VirtualHost>

<VirtualHost *:443>
    RewriteEngine On
    ProxyRequests Off
    ProxyPreserveHost On

    <Directory "/opt/abiquo/tomcat/webapps/client-premium/">
        Options MultiViews
        AllowOverride None
        Order allow,deny
        Allow from all
    </Directory>
    RewriteRule ^/client-premium$ /client-premium/ [R]

   <Location /client-premium>
        ProxyPass ajp://localhost:8010/client-premium/
        ProxyPassReverse ajp://localhost:8010/client-premium/
    </Location>

    <Location /api>
        ProxyPass ajp://localhost:8010/api/
        ProxyPassReverse ajp://localhost:8010/api/
    </Location>

    <Location /legal/>
        ProxyPass ajp://localhost:8010/legal/
        ProxyPassReverse ajp://localhost:8010/legal/
    </Location>

	<Location /m/>
        ProxyPass ajp://localhost:8010/m/
        ProxyPassReverse ajp://localhost:8010/m/
    </Location>

SSLEngine on
SSLProtocol all -SSLv2
SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM:+LOW
SSLCertificateFile /etc/pki/tls/certs/ca.crt
SSLCertificateKeyFile /etc/pki/tls/private/ca.key

</VirtualHost>

Configure Tomcat

Delete all existing Connector sections.

Put this connector configuration in /opt/abiquo/tomcat/conf/server.xml under <Service name="Catalina"> section:

...

Code Block

<Service name="Catalina">

    <Connector port="8009" protocol="HTTP/1.1"
               connectionTimeout="20000"
               URIEncoding="UTF-8"
               redirectPort="8443"
               secure="true"
               />

    <Connector port="8010" protocol="AJP/1.3"
               enableLookups="false"
               tomcatAuthentication="false"
               connectionTimeout="20000" secure="true"
               />

Enable HTTPS in the client

Edit /opt/abiquo/tomcat/webapps/client-premium/config/client-config.xml.jsp and change USE_SECURE_CHANNEL_LOGIN value to 1:

Div

class	verysmallcode

Code Block
... <name>USE_SECURE_CHANNEL_LOGIN</name> <value><%= System.getProperty("client.USE_SECURE_CHANNEL_LOGIN", "0") %></value> ...

Notice that if you enable this option, you will not be able to connect to Abiquo with this client using the HTTP URI, as it only connects to SSL enabled URIs

Change API properties

Notice that if you enable this option, you will not be able to connect to Abiquo with this client using the HTTP URI, as it only connects to SSL enabled URIs

Change API properties

Edit /opt/abiquo/config/abiquo.properties and add this line (or modify the value if it already exists):

...

:

Code Block
... abiquo.server.api.location = http://localhost:8009/api

Restart Services

...

Code Block
service abiquo-tomcat restart service httpd restart

Now all client-server communication will go through a Secure Socket Layer. You can still use HTTP direct connection to Tomcat through port 8009.

...

Code Block
http://<public_ip>:8009/am

...

Adding SSL to AM

On the machine where the Appliance Manager (AM) is running, repeat the above steps (Install Apache with mod_ssl, Generate keys, Configure Apache and Configure Tomcat).

...

Stop Apache on the AM (/etc/init.d/httpd stop)
In the database the URI of the Appliance Manager in remote services now points directly to the API, which means the URI should be something like "https://server263:443/am"
Restart the abiquo-tomcat service on both machines. Remember to restart Apache on the API+Server machine as well.

...

Apache Frontend + SSL to client + SSL to AM in Abiquo 3.x

The following configuration has been performed in order to avoid Cross-Origin (CORS) problems with the new Abiquo client in HTML5 using Apache + SSL.

The best way to go approach is to complete all the previous steps, then we will have to do make the following modifications:

In the /opt/abiquo/tomcat/conf/server.xml, we should remove the connector which uses port 8010 and leave the file like this:

Code Block
<?xml version='1.0' encoding='utf-8'?>

The next step will be to modify /etc/httpd/conf.d/proxy_ajp.conf file and change ports from 8010 to 8009, which is the only connector we will use with the AJP. Keep on mind Remember to leave the AM location with the port 8010 as explained in the previous part "section (Adding SSL to AM"). The file should be like thisas follows:

Code Block
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so

...


<VirtualHost *:80>

...


RewriteEngine On

...


RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [L,R=301]

...


</VirtualHost>

...


<VirtualHost *:443>

...


RewriteEngine On

...


ProxyRequests Off

...


ProxyPreserveHost On

...


<Directory "/opt/abiquo/tomcat/webapps/ui/">

...


Options MultiViews

...


AllowOverride None

...


Order allow,deny

...


Allow from all

...


</Directory>

...


RewriteRule ^/ui$ /ui/ [R]

...


<Location /ui>

...


ProxyPass ajp://servermaster:8009/ui/

...


ProxyPassReverse ajp://servermaster:8009/ui/

...


</Location>

...


<Location /api>

...


ProxyPass ajp://servermaster:8009/api

...


ProxyPassReverse ajp://servermaster:8009/api

...


</Location>

...


<Location /legal/>

...


ProxyPass ajp://servermaster:8009/legal/

...


ProxyPassReverse ajp://servermaster:8009/legal/

...


</Location>

...



SSLEngine on

...


SSLProtocol all -SSLv2

...


SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM:+LOW

...


SSLCertificateFile /etc/pki/tls/certs/ca.crt

...


SSLCertificateKeyFile /etc/pki/tls/private/ca.key

...


<Location /am>

...


ProxyPass ajp://rsmaster:8010/am

...


ProxyPassReverse ajp://rsmaster:8010/am

...


</Location>

...


</VirtualHost>

...

The last file which needs to be modified modify is /opt/abiquo/tomcat/webapps/ui/config/client-config.json. Once there, Edit it and search for the "config.endpoint" attribute and leave it like this:, which should in this format:

Code Block
"config.endpoint": "https://servermaster:443/api"

Remember, Replace "servermaster" is with the hostname of the Abiquo server where the API and the client are running.

Last step is Then restart the abiquo-tomcat service on the API+client machine and restart the Apache as well.
