Server Cluster Setup

Feb 23, 2008

I have started to move my websites over to my UK Colocation But would like a little guidence on what the best solution would be.

I would like to build up a Server Cluster that will handle all of my sites really and also have redundancy, so If 1 server goes down the other Web/SQL/Whatever server will be used instead.

I have websites ranging from large forums to streaming & download websites.

Should I got for a setup for example:

X Web Servers + X Database Servers
Connected to X Storage (see link below)

Connecting the Web Servers in something like a a round robin config or use a Load Balancer / Other

OR Should I setup multiple:
Web Server + Database Server + Media Server

OR another config?

Below are my current setups

Current UK Setup (Colocation)

Web Server
Quad Core, 8GB Ram, 250gb HDD Raid 1
Quad Core, 8GB Ram, 250gb HDD Raid 1 (just ordered)

SQL Server
Quad Core, 4GB Ram, 250gb HDD Raid 10

Storage Server
HP StorageWorks NAS 1200s 1TB (just Ordered)
Link: [url]

Current US Setup (Dedicated Servers)

Web Server
Quad Core x2, 8GB Ram, 3TB HDD

SQL Server
Quad Core x2, 8GB Ram, 1TB HDD

Media Server
Quad Core x2, 8GB Ram, 3TB HDD
Dual Core, 4GB Ram, 3TB HDD

Backup Server

How To Setup Cluster/High Available Server

Nov 7, 2009

i have ideas about clustering server with spread country/datacenter.

example: i have 5 Server spread around the world, server 1 in US, server 2 in German, and other country for next server.

server 1 will be main server, when server 1 down, it will goes to server 2, and continue to the next server.

all site/file and other stuff will be mirror on all server.

so it will be 100% Uptime!, and never LOSS anything!.

and my question is how to do that, maybe someone expert want to share with me.

Domain Name Server (DNS) Cluster Setup In Cpanel

Jul 7, 2009

Hi there, i have few question for the best suited DNS Setup for our compagny.

We have tree server located in montreal.
Two are running web services, one of them is only for dns ( home server ).

Two main server have Whm/Cpanel.
One run Cpanel Dns only.

Main server have 7 ips each
Dns server, only have 1

Let say we use domain xxx.com
Right now we have ns1/ns2/ns3/ns4 point to server1
ns5/ns6/ns7 point to server2

We have no Nameserver that point to our dns only server for now.
I'd like to advoid runing DNS Service on all of them, maybe having two slave one master would be fine. Question: What would be the best suited dns setup with my current config for best responding time and fast replication?

Multiple Server/Cluster Design, Setup And Maintence

Mar 13, 2008

I work in a DC and am looking for a better way to deal with clients who have multiple servers hosted with us.

Heres the scenario. Client buys a server or two at the beginning, with a HW firewall or they are clustered together and require their own switch and down the road, they like what we do and want to buy more servers.

However, we've been selling other servers and the only way we would be able to accommodate them would be to run a cross connect to another cab with their new server in it. Hopefully you can see where I am going with this.

This can keep happening multiple times and with multiple clients. and eventually you can end up with spider web of cable everywhere .

My thought of doing it right but more work would be to schedule down time with a client and migrate all the HW to a new cabinet where they can grow.

Weve also been tossing around ideas like getting projected growth from clients and setting aside space for them to having dedicated cluster cabinets.

how do other DCs handle situations like this?

Domain Name Server DNS Cluster

Jul 27, 2006

I´m running 4 servers on a cpanel - dns - cluster.

- 1 running cpanel (srv01)
- 3 running cpanel-dns-only (cluster01 - cluster03)

My DNS config is:

srv01 - dns1.domain.com
cluster01 - dns2.domain.com

I ´ve setup on srv01:
- cluster01 (synchronize changes)
- cluster02 (standalone)
- cluster03 (standalone)

On cluster01:
- srv01 (synchronize changes)
- cluster02 (standalone)
- cluster03 (standalone)

And on cluster02 and cluster03, I did something like that:
- srv01 (synchronize changes)
- cluster01 (synchronize changes)
- cluster03 (standalone)
And
- srv01 (synchronize changes)
- cluster01 (synchronize changes)
- cluster02 (standalone)

1. So, is that correct?

2. It seems that when I click on 'syncronize all DNS records on all the servers' only cluster01 and srv01 got all the DNS records. So is it normal?

Yet If I add a domain on cluster02 for example, where I need to add the DNS? cluster02 named.conf or on cluster01/srv01?

Server Cluster & RAID HDD

May 27, 2007

put together a high availability cluster for a PHP + MySQL based app to run on a LAN. We're going to use Linux, and cost is a major consern. The app itself doesn't use / need too much resources, as it will only be accessed by 2 / 3 people at a time, so I'm using the following:

2 identical PC's with:
3Ghz PIV CPU
1GB RAM
2x SATAII 160GB HDD space setup as RAID 1
10/100 Mbps LAN NIC's, on a 100MB 8 port switch

Up to now I have been running MySQL-Max 5.0.15 to run a MySQL master-master replication server, which works fine, but the setup involved a lot of manual work, and downloading of the right binaries.

Furthermore I used Linux Heartbeat todo auto switchover between the two servers & RSYNC to sync the application files between the two. This has been working fine untill one of the server's HDD's failed recently corrupting both HDD's

So, I need a better way of doing this, and want to meet the following requirements:
If 1 HDD fails on either server, the server still needs to be able to run without a problem.
Replacing a HDD & rebuilding the RAID array should be easy to manage, preferabbly over the net.

Setting up a cluster should be easy to manage, both for the MySQL DB server & the files that need to be synced between the two machines Re-installing the server should be easy todo as well.

For No.1 I have been thinking of setting up RAID 5 with 4x HDD's - how reliable / safe / redundant is this?

For No. 4 I have been thinking of using something like sysimager to backup the server once setup, but will / can it recreate the RAID array upon restoration? The MySQL DB & PHP files are being backed up to a removable HDD on a daily basis.

The client is 700Km's away, so we can't just drop-in to fix things as often as we like. Thus redundancy is of utter importance. Currently I'm running Suse 9.3, simply due to the fact that it's easy enough to tell the client over the phone howto do things with YaST. Suse 10.1 will be used for the new setup, but I could also use Fedora Core 5, and have also been thinking of using SME server 7.0.

Email Server Cluster - Over 2 / 3 VPS's

Sep 1, 2007

Was thinking about running an email server for some local businesses, so they can out source their IT systems (cheaper).

Now setting up a mail server, say running DirectAdmin is normally fine.

However this is a "mission critical" service to these guys, so I want 9.9999% uptime !

I was thinking of getting a few VPS's around 384MB RAM, 20GB HDD spec in the same DC but on different nodes and setting up a cluster...

And then I thought..... How the hell do I do that..? WHT must know.....

Static Server + Forum Cluster

Oct 23, 2008

my current servers are part of this mess with Alphared:
[url]

what I'm looking for:

static content main server:
average cpu, average ram
15-20gb data tops, but could use a fast drive
need about 6tb/m of higher quality bandwidth
2 machine cluster for forums

only thing on this will be vBulletin forums.
current database is about 6gb (~7 million posts)
averaging about 800 members active per 15 mins
this isn't for a business, so it all comes out of my pocket. however, after the $#@! with Alphared I do recognize the importance of a good host and I am willing to put money toward that as needed. however, my goal is in the $600-$800/m range for everything.
is that price range doable? if not, what is a reasonable price for what I'm asking? and can anyone recommend reliable hosts (especially one that can correctly setup the cluster for the forums).

Load: Upgrade Server Hardware/software Or Set Up Cluster

Apr 9, 2008

We have a quad code with 8GB ram dedicated for one website, but still the load goes through the roof and crashes the server. The site has one vB forum (with minimum hacks), and a custom CMS for the front pages which uses a minimum of queries.

I'm not an expert, but it would seem like mySQL is the one that crashes. When the site crashes and someone browse the site, you can see the "could not connect to mySQL through socket" error message. At that point the load just skyrocket (been up to 4-500), and then the server crashes and has to be rebooted.

* Is our only option to make some sort of cluster?
* Could upgrading to i.eg Apache 2.x or installing an op code cacher like xCache help?
* Is it possible to run the databases from RAM to save IO (so it only writes to the HDD on update/insert/delete etc)?

I have root access, so if you need me to run more commands to look up statistics, just let me know.

Plesk Automation :: PPA Cluster - Creating Dedicated Server?

Feb 4, 2015

I've added a new Apache/MySQL node to our PPA cluster and we'd like to be able to host a single subscription on that node for the Apache webhosting and MySQL databases for that subscription while allowing that subscription to utilized the rest of the shared resources in the cluster, such as mail, DNS, etc. I'm looking for the best way to go about doing that.

I guess one simple way would be to set the new server to 'ready to provide' and set the rest to not ready, add the "linux shared hosting" hosting subscription to the customer account, then switch the new server to not ready and the rest back to ready. That works fine I suppose in a small cluster, but there has to be a better way. Is there a way to craft a service template that restricts subscribers to a particular node for Apache + MySQL and leaves them to rest of the "regular" nodes in the cluster for other services?

File Server Setup With Nginx...how Do I Choose The Config For The Server

Apr 22, 2009

I just want to use a server for file sharing, it will have nginx and that's it. I'm looking at centos, or freebsd, but I been using centos forever now and I'm not sure how to use freebsd, should I just stay with centos?

Do I tell my hosting provider to just install the OS and give me ssh action and that's it? Don't install any control panels or any other stuff? I want one domain and one subdomain on it though and ftp action.

Dedicated Or Reseller Setup With Virtualization Or Decent Chroot Setup

Jul 31, 2008

As my clients' needs expand, they're asking for chroot ssh/sftp setup. I'm currently on a dedicated Linux setup but don't really have the time to set up a whole new box with full virtualization or investigate a full chroot solution (baby on the way), and to be honest it would be less hassle to move to a new provider than worry about down time with sites.

What I'm looking for:

- linux hosting
- hosting for 30+ accounts, some with several domains
- at least 6 IP addresses for SSL certs
- each account in a full chroot environment (ssh/sftp/ftp) so they can't poke around each others' files, or each account set up in a virtual machine setup (ie: openvz)
- maildir
- spamassassin
- php 5, mysql, perl 5.8.8
- suexec apache would be nice

Web Server Setup VPS

May 7, 2009

I've registered a new domain name and 'hired' a Virtual Private Server (not managed) to host it. I know 'some things' in php and web design but I'm newbie with configuring servers (especially remotely on a Linux server.... )...

This is what I've done so far :

1. registered domain name at namecheap.com and set up DNS there (my VPS server names)

2. I've installed Linux Ubuntu 8.04 on my VPS

3. I've downloaded and installed XAMPP 1.7.1 on my VPS

I've registered my domain name yesterday and it is still 'invisible' when I type in the address... BUT when I type in my VPS's IP address, the XAMPP welcome screen appears (MySql isn't running though...).

I know this is a child's play for a Linux expert, please if someone knows a good tutorial, step-by-step guide on how do I set up everything to work properly....

Setup FTP Server

May 15, 2008

if I could assist his small company in setting up an FTP server. What they are looking to do is provide a way for people to login and access files. They can either bring down the files that are left for them or they can upload files. Is setting up an FTP server difficult? Is it time consuming? Can you customize it so that certain files can only be seen for specific usernames?
