Converting a Single WordPress Site to a Mulisite


Multisite is an interesting feature I have not tried before and currently exploring. I used single site for many years and currently working on a project to set up multi-language site which I believe Multisite will be best fit into this situation since multisite WordPress installation allows me to create and manage a network of multiple websites from a single WordPress dashboard.

Install Nginx, MariaDB, PHP (LEMP) and WordPress on GCP Free Tier Ubuntu


I was using LAMP for my WordPress blog for quite a few years. Because of Google Cloud Platform free tier VM's limitation (614M Memory and 1 vCPU), my website always suffering the performance issue if put all of components into one machine. Since last year, I keep trying using a different type of technologies to help. I tried to use Docker, also I separated Mysql db into a different vm. All those changes were working for certain conditions, but not a good enough for GCP f1.micro VM until I find Nginx and MariaDB. This combination has less resource usage and also providing me a possibility to squeeze all components into one GCP free tier f1.micro VM.

This post is to record all steps and commands I used. You will find a YouTube video at the end of post to present the installation process. The whole steps will take 30 minutes to 45 minutes to complete.

I were using Ubuntu 16.04 as my web server and mysql server for quite a few years. They are all in the same server , either running in a docker container or in a service. For better performance, I decided to separate them to different layer. I am going to use GCP Cloud SQL service as my database layer.
