I'm currently trying to deploy my Django 2.0 App on an Apache Web Server. However I'm experiencing difficulties in configuring it because my Virtual Host configuration overrides other Virtual Hosts which is used by other projects (Ruby and PHP WebApps). We only have one domain name at the moment so I cannot use other domain names to host my app.

Is it possible to serve different kind of apps with one domain name using Apache Virtual Hosts?

Since you can only have 1 VirtualHost (one domain, one port, one IP), you cannot create additionnal VH. You need to "split" the paths to the different applications some other way.

Let assume www.example.com:

ServerRoot "/some/path/apache"

[...] OTHER LoadModule directives [...]
LoadModule alias_module modules/mod_alias.so

Listen *:80
<VirtualHost *:80>
ServerName www.example.com
ServerAlias example.com

# Logs
LogLevel warn
CustomLog "logs/www.example.com_access-log" combined
ErrorLog "logs/www.example.com_error-log"

# Index file. Add as many as required for your applications
<IfModule dir_module>
DirectoryIndex index.html
</IfModule>

# Where the documents are
DocumentRoot "/some/path/apache/htdocs"

<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
</Directory>

<Directory "/some/path/apache/htdocs">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
</VirtualHost>


This VirtualHost is a basic configuration for the www.example.com domain. Now you want to have Ruby, PHP WebApps and Django 2.0 App under that single domain. You have 3 choices:

DocumentRoot

Alias

Create /some/path/apache/htdocs/Ruby, put your Ruby app. here.
Will be accessed via http://www.example.com/Ruby

/some/path/apache/htdocs/Ruby

http://www.example.com/Ruby

Create /some/path/apache/htdocs/PHPWebApps, put your PHP app. here.
Will be accessed via http://www.example.com/PHPWebApps

/some/path/apache/htdocs/PHPWebApps

http://www.example.com/PHPWebApps

Create /some/path/apache/htdocs/Django, put your Django app. here.
Will be accessed via http://www.example.com/Django

/some/path/apache/htdocs/Django

http://www.example.com/Django

The URI value must match the directory value.

Alias

If you do not need, or want the URI to match the directory name (like in 2.), use Alias.

Create /SOME_DIR_FOR_Ruby, put your Ruby app. here.
Add Alias "/Ruby" "/SOME-DIR-FOR-Ruby"
Will be accessed via http://www.example.com/Ruby

/SOME_DIR_FOR_Ruby

Alias "/Ruby" "/SOME-DIR-FOR-Ruby"

http://www.example.com/Ruby

Create /SOME_DIR_FOR_PHPWebApps, put your PHP app. here.
Add Alias "/PHPWebApps" "/SOME_DIR_FOR_PHPWebApps"
Will be accessed via http://www.example.com/PHPWebApps

/SOME_DIR_FOR_PHPWebApps

Alias "/PHPWebApps" "/SOME_DIR_FOR_PHPWebApps"

http://www.example.com/PHPWebApps

Create /SOME_DIR_FOR_Django, put your Django app. here.
Add Alias "/Django" "/SOME_DIR_FOR_Django"
Will be accessed via http://www.example.com/Django

/SOME_DIR_FOR_Django

Alias "/Django" "/SOME_DIR_FOR_Django"

http://www.example.com/Django

This is where you could use multiple VirtualHosts. But you have to be able to create sub-domains. This is done either via a DNS configuration, or through your hosting provider.

You could setup http://ruby.example.com, http://php.example.com, http://django.example.com. Each of these will have 1 VirtualHost, but will all be mapped to the same IP in the DNS.

Then setup 3 VH:

<VirtualHost *:80>
ServerName ruby.example.com

# Logs
LogLevel warn
CustomLog "logs/ruby.example.com_access-log" combined
ErrorLog "logs/ruby.example.com_error-log"

# Index file. Add as many as required for your applications
<IfModule dir_module>
DirectoryIndex index.html
</IfModule>

# Where the documents are
DocumentRoot "/some/path/apache/htdocs/Ruby"

<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
</Directory>

<Directory "/some/path/apache/htdocs/Ruby">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
</VirtualHost>

<VirtualHost *:80>
ServerName php.example.com

# Logs
LogLevel warn
CustomLog "logs/php.example.com_access-log" combined
ErrorLog "logs/php.example.com_error-log"

# Index file. Add as many as required for your applications
<IfModule dir_module>
DirectoryIndex index.html
</IfModule>

# Where the documents are
DocumentRoot "/some/path/apache/htdocs/php"

<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
</Directory>

<Directory "/some/path/apache/htdocs/php">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
</VirtualHost>

<VirtualHost *:80>
ServerName django.example.com

# Logs
LogLevel warn
CustomLog "logs/django.example.com_access-log" combined
ErrorLog "logs/django.example.com_error-log"

# Index file. Add as many as required for your applications
<IfModule dir_module>
DirectoryIndex index.html
</IfModule>

# Where the documents are
DocumentRoot "/some/path/apache/htdocs/django"

<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
</Directory>

<Directory "/some/path/apache/htdocs/django">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
</VirtualHost>


On Apache 2.2, you have to add NameVirtualHost *:80, in Apache 2.4, nothing, it is always "on".

NameVirtualHost *:80

All these values can be changed as you like, this is just an example to explain the concept.
