Nam Huy website is coming back

Nam Huy website is coming back after had been offline for many months due to my mistake on database backup method. Rather running mysqldump command to backup database, I had cronjob backing up the whole mysql’s databases directory. After I upgraded mysql server version and reinstalled mysql server a few times, I could not make mysql server to read those old databases directory.

I do have all databases but with new mysql server installation, old database does not have correct table ID with new mysql. I end up can’t mount old database with new mysql server installation. I have been researching and trying to restore old databases to be working with newer mysql server but no luck so far. And since I’m quite busy with my daytime job, I decided to start over again. I learned my lesson hard way even though I have my backup in many places but I made big mistake on backing up mysql database method.

Let’s start fresh again. Last time I mainly focus on Linux topics, but lately I have not been working with Linux but Windows, troubleshoot networking, and hardware. This time I think I will write just about everything related with technical topics.
