/usr/share/mysql/mysql-systemd-start contains:
pinger () {
while /bin/true ; do
sleep 1
mysqladmin ping >/dev/null 2>&1 && break
done
}
So if mysql failed to come up, this will hang forever.
However, I think mysql failed to start because it couldn't read some
config file. I saw that message somewhere back in history.
"service mysql start" also hangs:
poll_s S+ pts/12 0:00 | | \_ sudo service mysql start
poll_s S+ pts/12 0:00 | | \_ systemctl start
mysql.service
poll_s S+ pts/12 0:00 | | \_
/bin/systemd-tty-ask-password-agent --watch
poll_s Sl+ pts/12 0:00 | | \_
/usr/bin/pkttyagent --notify-fd 5 --fallback
But it isn't asking me for a password. Argh.
