At the top of your config file also add NameVirtualHost *:80.

comment Water-Cooled Rack Door: does it work well with Blades or GPU nodes?
I'd recommend that you use multiple racks. No need to put everything in one small area. Spread out the load. It'll be much easier to deal with from a cooling stand point.

Will this be in a data center environment? Are you space constrained?

I haven't personally used the SCL, but that blog post looks like a good writeup

Redhat includes MySQL 5.5 as part of the Software Collections. Maybe start there developerblog.redhat.com/2013/08/08/…

comment CentOS 6.5 / OpenSSL 1.0.1g still showing vulnerable to Heartbleed
It would appear that openssl was installed from a mechanism other than RPM. Did you install from source? The CentOS version that fixes heartbleed is openssl-1.0.1e-16.el6_5.7

You should confirm that your data center is using hot swap drives.

comment Are there typically rate limits to querying DNS?
How many queries per second do you think 8.8.8.8 handles? Do you really think you can DoS google?

comment How to secure tmp directory from hard link attacks when host doesn't allow partitioning
You'll need to benchmark on your own. There will be some hit, but you might not even be able to measure it in your own environment. It'll depend on how much you use /tmp and /home. I'd also recommend mounting /tmp with noexec,nosuid,nodev. I also didn't say anything about nfs, I was suggesting a loopback file system.

Using a loopback file system will cause a performance hit, but you didn't list performance as a requirement. It does solve the stated problem. So not prematurely optimize. :)

You might be able to setup a loopback file system for those mount points.

That is significant, but what would your counter measures be?

comment running commands on physical drives on different backplane with megacli
Is there more than one adapter on thus host? All of your commands use -aall. Maybe try -a0 or -a1.

comment How to use small SSD drive on server?
For their use case, it probably IS the best option. But if you're paging, even to an SSD, that's a sign that you need a bigger instance.

Machine M seems to be the natural choice for the NFS server.

comment How to fetch a cpu status thought net-snmp
This is highly defendant on the device and what it exposes over snmp. Some implementations (Linux, for example) allows you to define your own OIDs. Which device are you asking about?

comment Update packages on very old ubuntu
Replace that host. You're in for headache and heartache if you don't. The number of php vulnerabilities alone on that version is shocking. I'd recommend that you pick an LTS release given how often you have been updating your software.

comment How to start process as a daemon?
True, it's not quite that simple, but at least he's pointing the poster toward an actual daemon vs a hack with nohup or screen. Handle cwd and standard file handles then you get even closer to an actual daemon. Do you run apache in a screen session?
