To enable this without DNS, add the following line to your /etc/hosts file:
| Code Pro |
|---|
127.0.0.1 author.best-comics.net www.best-comics.net www.best-vinyl.net |
Apache setup
Make sure you have a working Apache on your local machine.
...
| Code Block |
|---|
apachectl configtest |
Enable mod_proxy, proxy_ajp_module
Make sure your Apache has the modules following module mod_proxy and proxy_ajp_module enabled.
Check the /etc/apache2/httpd.conf file and make sure the following line is lines are not commented:
| Code Block |
|---|
LoadModule proxy_module libexec/apache2/mod_proxy.so # more line in between ... LoadModule proxy_ajp_module libexec/apache2/mod_proxy_ajp.so |
On a different OS, the path and suffix of the module may be different.
...
We use virtual hosts configuration in this setup. You must make sure vhosts are enabled. Check the /etc/apache2/httpd.conf file and make sure the line with the include directive is not commented:
| Code Pro | ||
|---|---|---|
| ||
# Virtual hosts
Include /private/etc/apache2/extra/httpd-vhosts.conf |
If you edit the file, you must restart Apache.
...
If vhosts is properly enabled, edit the /etc/apache2/extra/httpd-vhosts.conf file and add something similar to this:
| Code Pro |
|---|
<VirtualHost *:80>
ServerName author.best-comics.net
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/
ErrorLog "/private/var/log/apache2/projekt.local-error_log"
CustomLog "/private/var/log/apache2/projekt.local-access_log" common
</VirtualHost> |
This configuration redirects the "author domain" author.best-comics.net to localhost:8080/magnoliaAuthor. The redirection works correctly, however, Tomcat still serves the pages from the context. Web resources do not load and redirections done by Magnolia are incorrect.

See line 37 - We ensure the context |
It works. The same can be done with the context magnoliaPublic instead of magnoliaAuthor.
...
We add two more virtual hosts to Apache. Here is the httpd-vhosts.conf with three virtual hosts, one for the author instance and two for the public instance:
| Code Pro | ||||
|---|---|---|---|---|
| ||||
<VirtualHost *:80>
ServerName author.best-comics.net
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/
</VirtualHost>
<VirtualHost *:80>
ServerName www.best-comics.net
ProxyPass / http://localhost:8081/
ProxyPassReverse / http://localhost:8081/
</VirtualHost>
<VirtualHost *:80>
ServerName www.best-vinyl.net
ProxyPass / http://localhost:8081/
ProxyPassReverse / http://localhost:8081/
</VirtualHost> |
Lines 11-12, 18-19: Note that the hosts www.best-comics.net and www.best-vinyl.net are redirected to localhost on port 8081, whereas author.best-comics.net redirects to localhost on port 8080.
...
This is the adapted Tomcat directory structure:
| Code Pro |
|---|
├── bin
├── conf
├── lib
├── webapps
│ ├── ROOT
│ └── magnoliaAuthor
└── webapps2
└── magnoliaPublic |
- Create the folder
webapps2. - Move the webapp
magnoliaPublictowebapps2.

Note the following:
- There are two
<Service>sections, theirnameattributes have different values. - Every
<Service>has its own<Connector> - Each connector must have its own distinct ports on the attributes
portandredirectPort. - The
portof the<Connector>is the same port to which we redirect on the Apache virtual host configuration.
