comment Apache IP based hosting solution shows apache test page and not the website
Is this public IP address configured directly at your server?

Have you checked X-Real-IP header on Unicorn side? Is it always 127.0.0.1 too?

Your IP is configured according to ifconfig output, what exactly is your problem?

What distro are you on? Do you have selinux enabled?

comment How to reset mysql's replication settings completely, without reinstalling it?
I guess the problem was with this /etc/mysql/var directory, you probably did not have it at all on the disk or permissions were wrong.

Do you really have /etc/mysql/var directory with owner mysql:mysql? You can check using ls -alFd /etc/mysql/var

The command above is valid for a command line SSH client, you can install it on Windows using Cygwin suite. You can also use PuTTY but port forwarding in PuTTY should be configured differently. PuTTY uses a graphical menu to configure such things.

comment Uninstalling MySQL for MariaDB Replacement on cPanel
Yes that will work but you should stop the MySQL server first. Please check the process list to ensure mysqld is not running.

comment MySQL started to consume about 40% of system CPU time and got unresponsive suddenly
Sure. But the system was restarted on Jul 06 so the leap second bug should be irrelevant.

Hmm good point, I just tried to stop it and si time was back to normal as soon as I did! So they were related closely. But I just can't get the reason of this relation, zabbix_server is a userspace thing so it should be a bug definitely. I will try to get a newer OpenVZ implementation but it looks like I will have to compile it myself.

comment Optimal number of per CPU unicorn processes
Good point, let's assume requests are distributed more or less equally and are pretty lightweight (we do have heavy requests in fact but they are handled by another pool of Unicorns). If all requests suddenly become heavy (e.g in case of I/O starvation on a DB node) we will be down regardless of per CPU instances number I guess. Well, probably the best way to know the truth is to perform some kind of load testing.

comment How to convert OpenVZ OS template to bootable image file?
Yes, you are right, copying /boot folder is not enough. I think copying /boot and installing GRUB using a LiveCD will lead you to a bootable system, but you will need to configure the network, etc as you pointed out.
