I have an ebs-backed ec2 ubuntu server which is running but unreachable.

There are very stupidly no recent backups.

I made a snapshot of the block, created a volume, spun up a new instance, attached the new volume. I see all the data from my site in the /opt/bitnami/mysql/data directory, but when I go into the mysql console, it shows only information_schema and test when I type show databases;.

How can I 'point' mysql to the correct folder?

Without knowing your setup its really hard to say but I see two possibilities:

  • Fist check permissions, and make sure that the files and folders under mysql/data belong to mysql:mysql
  • Next cat /etc/mysql/my.cnf | grep datadir That's where mysql is looking for your files. You can either copy the files there or change that line in /etc/mysql/my.cnf. Make sure to turn off mysql before you go messin' with the data files.

And, I can't jab enough that you should run backups on ec2. It's designed to be non-persistent storage. EBS only gives us a safety net that we shouldn't rely on. I suggest mounting your datadir in it's own ebs volume and snapshotting it with a cron. It's stupid easy to do. (admin jab over) – coteyr Dec 3 '12 at 22:46
ec2-create-snapshot -K $KEY -C $CERT -d \"`date`\" $vol in a cron should do the trick to create backups. -- $vol should be the volume id. – coteyr Dec 3 '12 at 22:50
Thank you - the snapshot was done. The backups were being run, BUT NOT UPLOADED TO S3!!!! This wasn't actually the answer - what I did was start a new instance, empty the /opt/bitnami dir and mount there. But thanks for the tips, they did help. And the admin jab was definitely in place. – hgolov Dec 4 '12 at 9:58
