Migrate OS from CentOS to Ubuntu

I have used CentOS for years and now I have to consider to master Ubuntu. Most commands could be found on both OS and they do share lots of concepts, while there are some differences and even I cannot upgrade the packages without searching the syntax of apt command.

The migration was simple and at the same time I upgraded the MySQL from 5.7 to 8.0 and PHP from 7.4 to 8.1, and upgrade the WP to latest 6.1 also.

These days I am busy in learning some new things and I have not touched Oracle more than one year, and also have not wrote a new post for such a long time!

I still believe database should be a critical component of the whole IT environments and when I finish my current learning of public Clouds and Kubernetes, I will refresh my knowledge of Oracle database, and will study more databases like PostgreSQL, MySQL and OceanBase.
