Problem with multiple subdomains-DocumenRoots on Ubuntu 18.04 and Apache2

Question

Hi guys,

I apologize if this is a duplicated question, I have been trying to find an answer through the related posts I have managed to find with no luck so far…

I have an apache2 server running on Ubuntu 18.04 (DNS for DigitalOcean set) with two subdomains: php.example.com and blog.example.com (DNS A Records set for the droplet IP). I installed phpMyAdmin (/usr/share/phpmyadmin) and a wordpress blog (/var/www/wordpress).

I wanted to access phpMyAdmin through php.example.com and the blog through blog.example.com / www.example.com but I cannot get to it; all the subdomains go to one of the DocumentRoots.

I have followed some tutorials (https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-virtual-hosts-on-ubuntu-18-04) and tips I have seen here and on different sites, and so far I have completed these steps:

Configured Virtual Hosts:

wordpress.conf: <VirtualHost *:80>

    ServerAdmin example@mail.com
    ServerName www.example.com
    ServerAlias blog.example.com
    DocumentRoot /var/www/wordpress

    <Directory /var/www/wordpress/>
            AllowOverride All
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

<VirtualHost *:443> ServerAdmin example@mail.com ServerName www.example.com ServerAlias blog.example.com DocumentRoot /var/www/wordpress

    SSLEngine on
    SSLCertificateFile /certroute
    SSLCertificateKeyFile /keyroute
    SSLCertificateChainFile /chainroute

    <Directory /var/www/wordpress/>
            AllowOverride All
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

phpmyadmin.conf: <VirtualHost *:80>

    ServerAdmin example@mail.com
    ServerName php.example.com
    DocumentRoot /var/www/phpmyadmin

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

<VirtualHost *:443> ServerAdmin example@mail.com ServerName php.example.com DocumentRoot /var/www/phpmyadmin

    SSLEngine on
    SSLCertificateFile /certroute
    SSLCertificateKeyFile /keyroute
    SSLCertificateChainFile /chainroute

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

Enabled both .conf files and disabled 000-default.conf / default-ssl.conf
Set up a symlink from /var/www/phpmyadmin to /usr/share/phpmyadmin
Reloaded Apache2

Still going to wordpress when I try to load https://php.example.com and at this point I really don’t know what to try next.

Any help would be much appreciated.

Thanks!

Sorry, @fgazpiazu , This is the right configuration, I made a mistake above. server { # Permanent redirect to new URL server_name php.yourdomain.com; rewrite ^/(.*)$ http://yourdomain.com/phpmyadmin permanent; } reload configuration: $ sudo systemctl reload nginx Add the following record in your DNS manager. CNAME php yourdoamin.com

Hi @fgazpiazu , You want to access PHPMyAdmin like this php.domain.com instead of domain.com/phpmyadmin . If you’re running an apache server and you have installed PHPMyAdmin, So the one thing is extra you have to do. Just create a symbolic link in apache2 directory to access the PHPMyAdmin: sudo ln -s /etc/phpmyadmin/apache.conf /etc/apache2/conf-available/phpmyadmin.conf sudo a2enconf phpmyadmin.conf Now, create a new configuration file in apache directory for you subdomain php.domain.com.conf, and add following lines ServerName php.website.com RedirectPermanent / http://php.website.com :/ Now when you open php.domain.com , it will redirect you to domain.com/phpmyadmin If you have install PHPMyAdmin in /etc directory, then this will work, otherwise, you have to make some changes.
