Question
MySQL stopped and it can't be restart
Hi there,
I have a big issue on my droplet.
Today, after pull from my git repo, I install a php extension (imagick).
After that, mysql began to start/stop frequenty, and now I am not able to restart it.
If i try:
sudo service mysql restart
It says me
Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
Log of journalctl -xe says:
