How Does Cent Os Pick Mirror?

Nov 5, 2009

I noticed with every new cent os server there are different mirrors for cent os repos.Since on each cent os repo file is same,how does it pick which mirror it pick?I ask beacuse latest server has picked one extremly slow edu mirror which is not just slow,it also timeout,and it may extend update to 2 hours instead 5 minutes which usually will take.So how do i change base mirror on base cent os repo?

Which Distro For Vps Did You Pick

Sep 6, 2007

This is a tough question cause the distro you choose makes all the difference.

So my question now is if your choices were:

Centos 4 or 5 (32bit or 64bit)
Ubuntu (32bit)
Debian (32bit)

which would you pick and why?

on a side note I believe that the distro that gets picked the most is the one that has the most servers and if someone were to pick one thats not favored by many then he/she may get a faster server cause there wont be so many VPSs on it. Correct in this assumption?

How To Pick A Shared Host

Apr 1, 2009

I've used two different shared hosts in the past. First host had little to no support and got slower and slower as time went on. Second host, has been fine for my personal blog and portfolio site, but the load time is way slow at certain times of the day.

How in the world do you find a shared host that is actually going to be fast? I know you don't want a host that is over-selling, but how do you know a host is overselling? I assume any host that is less than $10/mo and has unlimited everything is going to be oversold, but how do you find one that is going to be responsive. Trial and Error? I've been trying to read the reviews on sitepoint, but I feel like a lot of the time the reviewer is unaware of site load times.

I don't mind doing the research myself, but I can't figure out where to look or how to look.

All I want from my host is fast load times, all the time. I don't have huge traffic, I do have a lot of files, and it's very important when someone comes to my site it loads as fast as possible.

Obviously cheaper is nicer, but I don't mind spending a little extra to have a server that loads fast.

Failover Plan - If One Server Is Down, Pick The Second One

Apr 23, 2009

So, there is my example. I have two servers in different locations. First one is the main server with all the data and the second one has just simple notice like "We will be back soon".

Now, if I set the primary DNS server on main server and secondary DNS on second one (but with different A records), will users actually get the server two if main server is down?

Will this work or not? I want 100% access to the site, at least to the server with only notice (I don't need data from main server). I can set the round robin, but I don't need load balancing (actually I want access only main server), but just if main server is down to go on the second one.

Cent OS

Apr 23, 2007

I have a server in our office which is used as a share drive. Puts all accounting docs on it ect. After 6 or so, it will loss all conectivity completely. Yet the server still stays on. We installed everything in all packages on the server including it graphical interface. We havent mucked with any of the powersavings so what could it be. Also there is nothing plugged into it eg screen,keyboard and mouse. All that is connected is the power cable and the ethernet cable. That is it.

It is directly connected to a belkin wireless router

How To Check Which Version Of Cent Os Is Used

Jun 28, 2009

how to check which version of cent os is used?

my friend ordered an vps with a host, he ordered 5.3 - 32bit but some how I feel he has been provided with 5.0 version by the host, I didn't know how to confirm it, when I checked his hypervm, this was the cent os details provided:

Ostemplate: centos-5-i386-hostinabox576

there is rebuild option in the hypervm and in tht when I look out,here it shows the following:

what my friend exactly needs is a cent os 5.3 - 32bit system, so if he selects cent os 5.3-ix386 (full) will it install with cent os 5.3 ?? he doesn't want kloxo to b in there auto, he/I can install tht,

Do You Mirror? (If So, How?)

May 3, 2007

Ok here's a potentially dumb newbie question, but I have to know. How many of you mirror your sites, and how do you set it up?

Is it as simple as getting 2 different webhosts, and setting your DNS settings to
primary: DNS.HOST1.COM
secondary: DNS.HOST2.COM

And, in the event of HOST1 going down, will the magical internet genie know to direct all your traffic to HOST2?

Also, what's this I've heard something about a "round-robin DNS" setup? I read it in a thread in response to someone who was trying to manage bandwidth. The suggestion was to set up a bunch of mirrors with a round-robin DNS so that traffic gets split equally.

This is all very interesting & new to me. How do I do it?

Mirror/Mirroring Server

Jan 29, 2009

A great insight to alot of my research and thank you in advance for any advice given.

I have a server based in HK(with WHMCS) and host several websites. The speed and availability serves the Asia Pacific market/viewers well; but we have several new websites that also targets the European and North American viewers.

I have been researching on getting a dedicated server based in US to mirror our server. Therefore allowing the US/European market to access the website faster. Although we have a few problems (and very little budget to solve it too ;p)

1. We need to sync the two servers in real time ; rsync seems to be the best but is there any other reccomendations?

2. We will make the IP address in each servers the same, so our clients need not change their dns. Do we need IPcast/anycast?

3. Is there anything else that I may have oversight?

Mirror/Mirroring Server Solution

Oct 29, 2007

My company requires a Mirrored Server setup. I hope someone can direct me to the right solution which guarantees the least downtime.

- We have 20+ php/mysql websites.
- We need two dedicated servers hosted in 2 different datacentres.
- Users are directed to the first server.
- If the first server is down the users are automatically directed to the 2nd server @ the 2nd datacentre.
- The software/hardware which redirects the users need to be fail proof or have an instant backup which takes over incase that goes down too.
- Data (databases and files) needs to be synced correctly to avoid data not being mirrored correctly.

I've done some reading and there is alot of mention of the DNS round and load balancers.

However, it seems these two options are also not fail proof.

Would appreciate if someone could simply outlining what system would be best for us for 100% uptime incase of server failure.

Identical Mirror/Mirroring Servers Vs. RAID5 NAS

Nov 16, 2006

We are expanding our photo sharing business and are revising our Unix-based server architecture. We're looking to develop a standard server configuration so that we can easily add servers when necessary.

Our ISP has recommended a configuration with mirrored web servers and mirrored RAID5 NAS boxes. I've read about Google's server architecture which consists of identical mirrored servers; when a drive or part from one of those servers goes down, data is served from the mirrored servers and the bad machine is repaired or replaced.

Comparing the two architectures with similar storage sizes, the overall cost of the hardware itself is about the same, with the identical mirrored machines being slightly cheaper. The monthly co-location fees (rack, power, etc.) are higher for the NAS solution.

I'm interested to hear your thoughts and experiences with similar solutions. I know the web/NAS solution is popular, and it's probably the one we'll go with, initially at least. Has anyone here implemented a Google-like identical mirrored server solution?

Keeping Mirror/Mirroring Backups...anything Better Than Rsync?

Dec 17, 2008

Keeping mirrored backups...anything better than rsync?

I'm keeping mirrored backups of my servers. Does anyone know of any solution better than rsync to update the files on the backup server?

I've noticed that when running rsync it can cause a lot of disk i/o, which can slow down a running server.

Does anyone have any suggestions on how to decrease disk i/o or another solution to keeping mirrored backups on a secondary server?

Setting Up A Mirror/Mirroring Site With A 2nd Web Host

Aug 10, 2005

I currently have a mirror site set-up on a seperate server (with a seperate web hosting company) for risk management purposes.

For zero downtime dependability, a load balancer cluster checking both servers in real time, and directing traffic at only servers that were online has been suggested.

However this option is rather expensive. Does anyone know of any other options?
