Tempted to give it a try on a spare box, I look forward to any feedback from anyone who's tried it out too.
I imagine we'll see closer likeness to RHEL also.Last edited by FearData; 07-24-2014 at 06:07 PM.

I had it running on my laptop for a week or two. Even managed to install Steam and Civ V It ran great, till the HDD decided to die, and I've just not had the chance to replace the HDD yet.
Other than that, I have one VPS container (OpenVZ) running CentOS 7 but I've not really done anything with it.

I've had it installed on a devbox for a little over a week now. It is apparently a stable version of Fedora 19.
- Systemd instead of service
- Firewalld instead of iptables
- Xfs instead of ext4
- No ifconfig by default (can be installed, but they want you to use ip by default)
- ethX naming convention is gone, my devices are named enp6s0f0 and enp6s0f1
- grub2 instead of grub
- no MAKEDEV support
I'm not sure how I feel about these changes yet. These are just what I've noticed from fooling around with it for a week and a few other minor things. The ethernet device names are "supposed" to be better, but ethX was just simple. Grub2 is a bit different as you no longer edit the config directly, but I've used Ubuntu/Debian so I've already seen that before.
The changes from 6 to 7 seem to be a lot more than 5 to 6.
The major advantages from what I can see with 7 is:
- In place upgrades from 6.5 to 7.0. I haven't tried this yet but this is a great addition if it is well supported rather than having to reinstall the system.
- Kernel 3.10. Obviously loads of improvements made since 2.6.32.

Quite a few hurdles to overcome on this release with stuff like Cpanel / Plesk / DA / CSF / R1soft and all the add-on goodies we're so used to on 5/6. R1soft doesn't even support XFS from what I remember. In-place upgrades for anything but the most stock setups is going to be a huge mess. I'm actually quite surprised they made such drastic changes. Going to be interesting however it pans out.

Eh I wanted to setup a dev cPanel box running it, but the installer errors out saying it's not supported. That was the extent of my testing...

Does it have these issues with a typical multi-CPU Xen VPS which are (by default) presented as multiple single-core sockets?

Maybe if enough people show interest on this page cPanel will start working on supporting RHEL7 / CentOS 7;

Got as far as installing it on a KVM VPS and that is about all...
Seems OK, but as noted there are a fair few significant changes from 6 to 7.
One thing I do want to test is to bring up a 6.5 VM and then do an in-place upgrade to 7 to see how it works or if it is more trouble than it's worth.
Of course, need to evaluate the Linux containers and see if it is/will replace OpenVZ as a container-based virtualization, or just move over to KVM for VM's.
Yep, jsut when they seemed to sort out most of the issues with 6.x, along comes the next major release.CPanel Shared and Reseller Hosting, OpenVZ VPS Hosting. West Coast (LA) Servers and Nodes

No, that limitation is only when running on bare metal, see https://access.redhat.com/solutions/544423

Been testing CentOS 7.0 mainly on virtualised platforms from VirtualBox and RamNode CKVM VPS (via CentOS 7.0 netinstaller) to work on Centmin Mod LEMP compatibility - got Centmin Mod .08 beta working fine with CentOS 7.0
It's been an interesting experience with a lot of reading to do especially for stuff I am never used before (grub2, systemd vs sysvinit, firewalld on top (not replace) iptables and polkitd & tuned daemon etc).
not sure if tuned is needed ?
tuned(8) Adaptive system tuning daemon tuned(8)
NAME
tuned - dynamic adaptive system tuning daemon
SYNOPSIS
tuned [options]
DESCRIPTION
tuned is a dynamic adaptive system tuning daemon that tunes system settings dynamically depending on usage.
Code:tuned-adm active Current active profile: virtual-guest
Code:tuned-adm list Available profiles: - balanced - desktop - latency-performance - network-latency - network-throughput - powersave - sap - throughput-performance - virtual-guest - virtual-host Current active profile: virtual-guest
virtual-guest
This is pre-selected on virtual machines. The goal is best performance. If you are not interested in best performance, you would probably like to change it to the balanced or powersave profile (see bellow).
virtual-guest
A profile designed for virtual guests based on the enterprise-storage profile that, among other tasks, decreases virtual memory swappiness and increases disk readahead values. It does not disable disk barriers.
Code:cat /usr/lib/tuned/virtual-guest/tuned.conf # # tuned configuration # [main] include=throughput-performance [sysctl] # If a workload mostly uses anonymous memory and it hits this limit, the entire # working set is buffered for I/O, and any more write buffering would require # swapping, so it's time to throttle writes until I/O can catch up. Workloads # that mostly use file mappings may be able to use even higher values. # # The generator of dirty data starts writeback at this percentage (system default # is 20%) vm.dirty_ratio = 30 # Filesystem I/O is usually much more efficient than swapping, so try to keep # swapping low. It's usually safe to go even lower than this on systems with # server-grade storage. vm.swappiness = 30
Code:cat /usr/lib/tuned/throughput-performance/tuned.conf # # tuned configuration # [cpu] governor=performance energy_perf_bias=performance min_perf_pct=100 [vm] transparent_hugepages=always [disk] readahead=4096 [sysctl] # ktune sysctl settings for rhel6 servers, maximizing i/o throughput # # Minimal preemption granularity for CPU-bound tasks: # (default: 1 msec# (1 + ilog(ncpus)), units: nanoseconds) kernel.sched_min_granularity_ns = 10000000 # SCHED_OTHER wake-up granularity. # (default: 1 msec# (1 + ilog(ncpus)), units: nanoseconds) # # This option delays the preemption effects of decoupled workloads # and reduces their over-scheduling. Synchronous workloads will still # have immediate wakeup/sleep latencies. kernel.sched_wakeup_granularity_ns = 15000000 # If a workload mostly uses anonymous memory and it hits this limit, the entire # working set is buffered for I/O, and any more write buffering would require # swapping, so it's time to throttle writes until I/O can catch up. Workloads # that mostly use file mappings may be able to use even higher values. # # The generator of dirty data starts writeback at this percentage (system default # is 20%) vm.dirty_ratio = 40 # Start background writeback (via writeback threads) at this percentage (system # default is 10%) vm.dirty_background_ratio = 10 # PID allocation wrap value. When the kernel's next PID value # reaches this value, it wraps back to a minimum PID value. # PIDs of value pid_max or larger are not allocated. # # A suggested value for pid_max is 1024 * <# of cpu cores/threads in system> # e.g., a box with 32 cpus, the default of 32768 is reasonable, for 64 cpus, # 65536, for 4096 cpus, 4194304 (which is the upper limit possible). #kernel.pid_max = 65536 # The swappiness parameter controls the tendency of the kernel to move # processes out of physical memory and onto the swap disk. # 0 tells the kernel to avoid swapping processes out of physical memory # for as long as possible # 100 tells the kernel to aggressively swap processes out of physical memory # and move them to swap cache vm.swappiness=10

Installed it on a box, uninstalled it when it wouldn't work with the QLogic CNAs we use. Drivers wouldn't build for it so put ubuntu on instead.

It is a little like moving from linux to minix or something, lots of commands different. The ethernet naming is really weird and if you run configuration manually in system-config/network-scripts it does not seem to the the scripts that apply network config on boot if you are using NetworkManager service.

I'd prefer they instead work towards supporting Ubuntu. With huge changes between RHEL releases now, they might as well just do what they needed to do for a long time. They historically stuck with CentOS because changes between releases have always been light...until now.
