Question

Unable to install mysql-server on Ubuntu

Hello All,

I’m following the LAMP tutorial (https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-ubuntu-22-04), but I don’t seem to be able to install MySQL on Ubuntu 22.04 . I tried deleting my droplet, making a new one, and installing MySQL before anything else, but I still get the following after running “sudo apt install mysql-server”:

mysqld will log errors to /var/log/mysql/error.log

I’ve just worked out it was due to a lack of memory on the Droplet, I upgraded from 512MB to 1GB , and it now installs fine

I had the same issue. I solved it using this stackoverflow post https://stackoverflow.com/a/68843792

i.e.

sudo -i
dd if=/dev/zero of=/swapfile bs=1M count=1024
mkswap /swapfile
swapon /swapfile
exit
sudo apt install mysql-server
