Setup a Server

At Krenovate, we use the OpenLiteSpeed WordPress to set up interactive client websites and blogs.

OpenLiteSpeed WordPress

The OpenLiteSpeed WordPress One-Click app is based on a standard WordPress image, but includes several great performance enhancements, including LiteSpeed's popular LSCache optimization plugin. This Wordpress + OpenLiteSpeed + LSCache image tends to be more than 300 times faster than a regular WordPress image!

OpenLiteSpeed WordPress One-Click automatically installs OpenLiteSpeed, LSCache, WordPress and any dependences. It also automates initial setup for components like Object Cache and PHP OPCache to reduce the time it takes to optimize a web server.

Note

If you are a Tech lead, then the CPU choice should be discussed with the client and then created.

Note

Make sure to substitute with the Droplet’s IP address.

Script to add Domain

An interactive script that runs, will prompt you for the domain & sub-domain and further questions.

Please input a valid domain:

You can also automatically apply Let's Encrypt SSL if your domain is pointed to this server already. Enter y and your email address to finish the process.

Do you wish to issue a Let's encrypt certificate for this domain? [y/N]
Please enter your E-mail:
Please verify it is correct: [y/N]
