Important notice from cPanel Inc. - Regarding latest updates

Not sure where this should go, but I just got this in my mail.
Quote:


Please ensure to read the following message carefully as there is important information about MySQL and Automated process killers in relation to the cPanel 11.24 upgrade.
MySQL Root Password
---------------------------------
With cPanel 11.24 now available, it is imperative to ensure that you have set your MySQL root password before upgrading to the latest version of cPanel. If you have previously skipped this step, you can set it now using the "MySQL Root Password" function in WebHost Manager. Failure to set a MySQL root password may cause database corruption on systems running MySQL 4.1 with InnoDB tables. Please set your MySQL root password as soon as possible to avoid any issues. Machines without a MySQL root password set allow access to any database by any user so it is imperative that a password is set as soon as possible.
If you have moved /root
------------------------------
If you have set root's home directory to something other than /root, you will need to copy .my.cnf from root's home directory to /root/my.cnf. In the future, this process will be automated.
Automated process killers
------------------------------------
If you have a system in place that automatically kills processes taking up a lot of CPU time, you should disable them before running the cPanel update as the size of the update has triggered many of these systems. These process killers will kill updates or related process in the middle of the process and cause issues. If you have a failed update, you can force a re-update by running /scripts/upcp --force
Felt it should be posted incase anyone missed it. Feel free to move it if its in the wrong place. If your on their mailing list, you probably already got this.

Thanks.
This morning's update was a little strange. I'm wondering if this had anything to do with it.

Thanks for posting.

Thanks for the info. I wasn't aware of that until I read your post, although it doesn't apply to us so

So far I like the list of improvements that cPanel has posted, WHM/cPanel overall seems to be a little less resource-intensive and a little more responsive.
Thanks for the post on the warning however all of our systems updated with no issues

Just got this update from them too:
Quote:


It has been brought to our attention that backups are not running
properly on servers that have disabled /bin/tar. To eliminate this issue before
it becomes a problem please check the following:
Permissions on /bin/tar should be 755. This can be accomplished from
a root shell via the following command:
root@host [~]# ls -l /bin/tar
If the result of that command starts as follows you are all set and
everything should be working:
-rwxr-xr-x
If not, please execute the following command:
root@host [~]# chmod 755 /bin/tar
As always, if you have any questions or run into any problems our
technical team is standing by to offer any assistance you may need by accessing https://tickets.cpanel.net/submit/

Who will be so stupid not to set a mysql root password? That was one of the section you need to go through during the initial cpanel setup. X_X

Rather odd of an update to know specific caveats, but not attempt to fix them in any way, shape, or form. I hope this isn't in the stable or current branch yet.

It is fixing the blank root password that causes an issue. MySQL is dying when we're trying to set the root password. It happens pretty rarely and did not show up in our testing for the build as none of the 1000+ servers it was tested on did not have a MySQL root password set. We've added new code to help reduce the chance of occurrence to make it highly unlikely that MySQL will die on a root password being set. Unfortunately, if the server goes down at the wrong time, it may cause corruption to one or more databases.
If you experience a innodb error, here's a thread with recovery steps: http://forums.cpanel.net/showthread.php?p=457301
If you're unable to fix it or do not feel comfortable with those steps, please submit a support request. See my signature for the link.
