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.
