Thought this might be of interest to folks on WHT. We put together a solution using Nginx ( Engine-X ) to do Global Server Load Balancing. This solution lets you do GSLB without having to fork over $26k per site to F5 or Foundry.
Thought it would be of interest to both end-users as well as dedicated hosting providers who might want to make it into a service (eg. sell a dedicated host in Europe and the US as a group, with the solution pre-installed).
The entire project, including relavent configs is available for download in the latest ( issue 6 ) FREE issue of o3 magazine (o3magazine.com)
I'm doing a bit of research into the market of Global Server Load Balancing and I'm wondering if anyone knows of any web hosting companies that offer this service. I'm looking for companies large and small that have this service.
Looking for quick, easy global load balancing solution. This is actually for a temporary situation (we need to move to a new DC and need to make this seamless as possible). Linux solution preferred if possible. What can we use to get this achieved?
How exactly does it work? does it need VPN between locations or is client redirected to a different IP somehow?
We would consider dedicated hardware solutions provided that we can get 2 pieces for under $2,000 total (ebay i guess).
I'm working on a huge project that will take like 2 months or so to release. The thing is, as I expect, this site is going to grow massively. My question is, How can I handle lot of traffic and give lot of space to my users? With a load balancing right? or server cluster? my question is? how does this work? where do I get it? what are the prices like?
All info on it is appreciated, i want to start with one from day one, so I can handle the grownth of the site once it happens.
I run a pretty large website and it has outgrown the sever that the site is currently on so i was told to go with load balancing or a round robin solution. Have order a load balancer and a second server but don't understand the concept behind have a server cluster. my host told me that the data would have to be synchronized on both servers which i get but if everything is identical on both servers when i run out of space one and i cant add any more hard drives because all the slots are used up, if the data is identical wouldn't both servers be full and if i even added a third server would that one be full to if you understand what im saying.... anyway my point is that i know there is a way that you can add as many servers as you want to a server pool/farm but don't know what kind of configuration i would need. if anyone could help shed some light on this I would appreciate it thanks.
Just wondering if mysql load balancing is possible in a shared environment.
Example:
I have 3 shared accounts. On one server, I have the write and the 2nd and 3rd server I have the read (select). Or vice versa .. Would it be possible to create a php script to perform this function?
I've searched a bit on this topic, but noone seems to have any resolutions: I have a myriad of different websites on a server, and want to balance resources. What and how are the best ways to do this?
I bought two Dell R200 because they was extremely cheap.
My target is Open Source SAN with active/passive setup.
Now i was wondering what RAID-level I should go for.
I will use 1TB SATA-II disks.
1) RAID-1 in both servers and mirror each other with DRBD. With this setup i have like double RAID-1 so i lose lots of disk space. 4 disks -> 1TB
2) No-raid at all and i will mirror data with DRBD. 4 disks -> 2TB
Then there is change to go for RAID-5. Theres enough space to put third disk in that case
3) RAID-5 in both servers. Mirrors data with DRBD. 6 disks -> 2TB but more performance.
But in every setup i lose space more then i would like to.
Actually i dont need space more then 1TB, but i would like to get best possible redundancy and most space available i could.
Also need to remember that those servers does not support hot-plug HDs so in case there is disk-failure i need to be able to shutdown one server and iSCSI should still be up and running.
Of course theres change to make it active/active.
I was thinking that if I go for the RAID-5 I will make LVM-VG on both nodes (san-vg1 and san-vg2) and use it 50/50.
In case of fail both VG's will be used from working node.
Im going to use Debian Lenny I guess..
I was looking for OpenFiler because of the GUI, but im familiar with Debian and have always done everything from cmd.
I am tried to integrate Apache HTTP server and JBoss app server 7 with mod_jk module plugin in Apache.I have two instances of Jboss running and Apache server sends requests to them.I have added following code in "httpd.conf" of Apache:
But, though I have configured this way, when my worker1 goes down,Apache is not sending requests to worker2 and I get "Service Temporarily Unavailable" message.
if anyone replaces a commercial program with their own open source as for eg what Friendster did. For Netscaler, any open source development that are close are similar to it?
I have been getting multiple emails a month for a service which I have never purchased.
The information they have harvested off the internet (since I know where they found it) and have obtained solely for use in attempting to charge me is- Invoiced To Steven Crothers 12345 Main St., Detroit, MI, 48021 United States
Which is completely obvious that it is fake.
I respond to EVERY invoice with a cancelation request, yet the tickets that get opened in the WHMCS billing panel get deleted a day later, however I have tickets in there that I have opened by use of the ticket insertion form that have stayed - none of which were ever answered.
The latest ticket information- Department:Billing And Invoicing Date:09/10/2009 10:05 Subject:The Second Time... Status:Open Urgency:Medium
It's still open without a reply.
I have put tickets into their Kayako system as well (They have two support systems, I would assume its due to poor management of their company). One of which was answered, with simply the output of `uname -a` on some server somewhere with my name as the hostname.
I than have attempted to reach anyone via livechat at [url]they constantly tell me that I am not allowed to speak to anyone until I pay my bills up to current (now remember, I have NEVER ordered anything from them, they don't even have valid information on file). Just tonight I demanded that I required to speak to a billing agent or I would be pressing harrasment charges against them for the 23 emails I have recieved in 3 months from them trying to extort money from me. They than banned me from their LiveChat software.
I have no idea what to do at this point, they are just sending me bills every month. I mark it as spam, but its frustrating to have a company trying to extort money from me on a very regular basis.
Is there any Open source backup software available for web hosting companies? I have a few shared hosting servers and a few dedicated servers and I want to setup a backup server for the backup of the data and config files of the servers. Please give me the names of some good open source backup software.
I own a small tech firm, mostly in business to support the customer with basic repair and upgrade. In recent year, more and more of my SMB customer ask me about the hosting service of the CRM or CMS.
The question I have is, although the open source tool, such as SugarCRM and Drupal is free of charge, but will it be free for some one like me to offer the service to my customer, either the same or customerize it a little bit.
And if it can be done, what kind of precaution I need to take, so I will not be involved in the copy right battle later on.
the loads on my server is VERY HIGH and it needs to be upgraded fast.
I really have no clue as what to do... and i do not know any expert other than you people here - to help me out and put me on the right track.
i was thinking of
1) Getting a server with better CPU and more RAM 2) Load Balancing
However I know nothing of load balancing (other than how to spell it correctly )
1) Which of the above two options should i choose? 2) what are the extra costs in load balancing? 3) what should i know about load balancing before deciding? 4) How does load balancing work? I know there are two server - like one for database and one as webserver... but how does this work together? 5) what config should i be looking at in the two servers?
I'll stop here else i can go on and on and on...
I am giving the details of my server and service below, in case you guys need it.
We host a large number of small websites and are looking for high-availability and the ability to do maintenance on our application servers, so I'm looking for a load balancing solution. At this point, I'm considering Zeus ZXTM LB software, the Coyote Point e350si, and potentially an F5 1500 LTM.
The F5 solution is a total budget buster, and the Coyote Point UI is rough around the edges, but I've used them and they are reliable. Zeus looks like a winner with a great UI, but I haven't heard much about their reliability.
Bandwidth requirements are low at this point, so this is mostly about reliability and ease of configuration of a moderately complex set of services.
Any opinions on these vendors, or alternates I should consider?
I run a GSP (Game Server Provider) and i just baught 2 new octi xeon servers(Intel 5320)
i am having a problem with the load balancing, it dosen't balance de cpu usage on all cores but only on one, and it gets at about 80-85% and 3%CPU usage on the other one.
A couple days ago I bought 3 Dell Precision Desktop 360s for the purpose of Load balancing for a web server supporting Apache/php/mysql.
The Dells have: Code: Win XP Pro, 1 gb 3200 ram - can support up to 4, p4 2.4 ghz, 2 scsi raid 36 gb hdd How can I create Load balancing between 3 identical* web servers: by SCSI, network, or something else?
* Bought them all used. Quality tested the hardware, all of it identical.
