Frequently Asked Questions

What is the first step to deploy multiple WordPress sites on Synology NAS?

The first step to deploy multiple WordPress sites on your Synology NAS is to ensure that you have the Web Station package installed. This package allows you to host websites on your NAS. After installation, you should also enable PHP and the MariaDB package for database management. Once these are set up, you can create separate folders for each WordPress site within the web directory. Download the latest version of WordPress for each site and extract it into the respective folders. This sets the foundation for your multi-site deployment.

Can I use a single database for multiple WordPress sites?

Yes, you can use a single database for multiple WordPress sites, but it requires careful configuration. Each WordPress installation can be set up to use the same database by creating unique table prefixes for each site. This way, WordPress can differentiate between the tables of each site within the same database. When installing WordPress, you will be prompted to enter a database prefix; ensure that each site has a different prefix to avoid conflicts. However, for better performance and management, many users prefer to use separate databases for each site.

How do I configure virtual hosts for each WordPress site?

To configure virtual hosts for each WordPress site on your Synology NAS, navigate to the Web Station settings. Here, you can create a new virtual host for each site by specifying the domain name and the corresponding document root (the folder where the WordPress files are located). Make sure to assign the correct PHP profile and enable the necessary permissions. After setting up the virtual hosts, you will need to update your DNS settings to point the domain names to your NAS’s IP address. This allows each site to be accessed via its unique domain.

Is it possible to use HTTPS for my WordPress sites on Synology NAS?

Yes, it is possible to use HTTPS for your WordPress sites hosted on Synology NAS. To enable HTTPS, you will need to obtain an SSL certificate. Synology provides a built-in feature to obtain a free Let’s Encrypt certificate, which can be configured through the Control Panel under the Security section. Once the certificate is installed, you can enable HTTPS for each virtual host in the Web Station settings. It is important to redirect HTTP traffic to HTTPS to ensure secure connections for all visitors to your WordPress sites.
