Ubuntu Servers :: Best Way To Scale Up Server Set Up?
Sep 1, 2011
what is the best way to scale up server set up for a high growth site? without getting a heart attack, where you can just open up a beer and watch tv as you push a red button to scale the server. lets assume the site is getting 100,000 people a day.And, in thirty days, it will be getting 9 million people a month, and in a few months it will get 9 million people a day. (I know it is a bit crazy)How would you structure a roll out?
two load balancers, two front end app servers, two database servers, and a cdn.And as traffic builds up, you would up the front end app servers, and maybe add two slave database servers? and maybe replicate the servers to east and the west to serve different parts of the world.What kind of hardware? I know it is a bit weird question, and it matters a lot on app, server hardware, server set up, style, class, lifestyle etc - I just want to see if there are any aha moments and awesome set ups that I am not aware of.
I just finished getting a semi-old desktop computer up and running with ubuntu server edition. It's running subversion and samba for my office of 5 people. I was wondering if there was a simple online/cloud based backup service to automatically back up my subversion repository and samba shares in case of any hardware problems?
The Linux samba server would be part of the Windows domain.What's the best way to add shares for all of the students, assuming there is 200 students per folder? Is there a way to add a wildcard like $(USER) (that's logged in)//fileserver/ students/classof2011/Bill_Gates? Or would a directory path have to be created for each student?Either way is fine. I'm just curious what the proper protocol is for completing that task.
anyone of you could share if you have been using ubuntu for large scale website or critical mission project, say for 500.0000 secure transaction per 3 hours with 4 million users accessing server. how does ubuntu perform?
I'm trying to design an inexpensive large scale DNS server but fail to find any metrics or methods to base scalabilty.Can anyone offer information on building a stable dedicated DNS server? That might be able to scale well.
Was wondering if its possible to scale ubuntu theme/environment to suite 1920x1080. Im using my comp on a 42" plasma TV, and it gets kinda small with the default scale.
Don't want to change to a lower res, simple because it's not as pretty and the toolbars are almost hidden.
Running Ubuntu 10.10..When you activate expose you see all your virtual desktops, but in each one the windows are overlaid. I want it to scale (ie show all windows on a grid) in each virtual desktop in the expose view. Does anyone know how to activate the scale plugin while in expose?
I have just upgraded from 10.04 -> 10.10 and my 'scale' plugin is not working properly in compiz (the rest works well).I do have the effect working with "super+a, super+w" , but "edge" does not work.I can modify values via gconf, I have: "initiate_all_edge" set to "BottomLeft" but this doesnt respond.The weirdest thing is that the compiz scale options part instead of giving me 4 tabs of options -> gives this.(image below) i tried reinstalling a few times & purge compiz + install back, but result remained the same.
How can I get the scale plugin to show windows from all workspaces like I could before with 10.04 and Gnome?With Unity the scale plugin only "scales" windows that are on the current desktop/workspace.
I have a dual monitor setup and I've used Scale for a few days now, but I'm still confused about the expected ordering of the windows within the same workspace. For example, the last focused window isn't necessarily placed at a fixed spot, e.g., top left corner. It seems that if a window on my left monitor is last focused and I invoke it on my right screen, then it'd appear on the top left corner. However, if a window on my right monitor is last focused, it gets past just the last focused window on my left monitor. The last focused window on my left monitor eventually shifts to the bottom right corner.
I want my webcam to be gray-scale when I use it in Skype and with other programs. I know I can make it gray-scale with Cheese, but that is only with that program. In windows it is a program called Manycam that allows the user to play it in the background and makes the webcam gray-scale over all. Is there an equivalence to Manycam for Ubuntu?
I would like my CPU to be overclocked, while retaining frequency scaling capabilities. The CPU is a Core2 Quad Q6700, with a stock speed of 2.67 GHz. In my BIOS, I can manually increase the FSB, but if SpeedStep (EIST) is enabled, the increased FSB is ignored by Linux, and the max speed remains 2.67 GHz. If I disable SpeedStep, then the CPU successfully runs at the higher speed I would expect, but does not scale down when under low load. As it is now, I am only running it at 2.8 GHz.Does CPUFreq *require* SpeedStep to be enabled in the BIOS?
I am using ubuntu 10.04 with kolourpaint 4.4.2.Recently I saw in windows 7 professional that paint program has feature to show grid & scale in centimetre.This is useful in drawing geometric sketch.In my kolourpaint : show grid-ctrl+g in view menu is grayed out. What can I do ?Is there a binary available for latest version ( because compiling from source is tedious ) ?
Is there a way that I can specify the height and with of the stream on the command line? From what I read, it looks like a #transcoder option would work, but I cant seem to figure it out. The above command is working, and I can view the stream, but it's extremely slow, and continuously freezes and buffers. My thinking is that if I can reduce the scale of the video.
I have had trouble with my wine window. It was scaled too small and i cant reach the controls to scale it back. If i just grab the sides, it just glitches up.btw it works on different desktops, but i just want to use my own desktop because it gets a bit annoying when i have to switch user to another desktop just to use wine)
I want to make an 8-bit looking image that has very large pixels. My solution was to make a 50x50 image, zoom in, draw it with the 1x1 pixel pencil tool, and then scale it to whatever size i want.Everything went well except, when i try to scale it the anti-aliasing kicks in and blurs everything. Is there a way that i can disable anti-aliasing?
I am looking for a way to place titles either on or under the previews in the Window Picker. I usually have many windows open, quite often with many of those windows being from the same program (i.e., OpenOffice Documents). I am wondering if the Scale plugin has some way of either overlaying titles when the mouse hovers over the preview, or if titles can be placed directly underneath the previews as they would be in OSX's Expose.
When moving the mouse to the right side of the screen quickly, all the windows are small.Previously I was the first thing I was stopped by removing the mark from the Scale, but now stopped while still influence the rest.
I have a very nice digital photo camera and I love to take my pictures at the highest quality setting available. My Canon is a 12 mega pixel camera so the photos get very large. After I shoot a weekend of 200+ pictures, the last thing I want to do is resize them so I can share them on Facebook. Does anyone know of a Linux program that will allow me to re-size multiple images rather than using Gimp to do each individual photo?
Does anyone have an example of a way to use ImageMagick or GIMP to Auto-White-Balance and scale 50% as a shell script? I'm asking because I usually do this to post-process photos in GIMP but being able to do this in a shell script means I could put it in Thunar in Xfce and save myself quite a bit of time.I checked the man page of mogrify and convert and didn't see any auto-white-balance type options that I am aware of
I have noticed that recently, cannot tell after which update, my mplayer does not scale to full screen. It just shows the movie in the center of the screen with black frame around it.I do not know how tightly it may be related, but xine-check says my X server does not support YV12 overlays (twice, BTW, so there must be a bug in its message file) and has no XVideo support.Is it normal in current for now? The card is X1200 (R690)
I recently setup my X to work well with the newer version of the ATI driver for my Radeon 3650, however no matter what I do, I can't get mplayer to scale to fullscreen. Something that xine has no trouble with. I have tried the x11, sdl, xover, gl, and gl2 outputs which all make no difference. Am I missing an output, or is something not working as it should? In particular, why is xine fine, while mplayer stumbles? As an unrelated question, it is possible to set mplayer to skip to a next file in a directory? From what I could tell, it does not seem to have this functionality built in.
I am using VirtualBox with Win-XP installed which works perfectly But after doing updates in my F13 today the scale wont work in the VirtualBox in full-screen mode Initially scale works when I place the mouse in the top-left corner but it's not working now and nothing happens Ive googled and tried settings in CCSM but I really have no idea why scale doest work in VirtualBox full-screen now this is really extremely inconvenient as i cant switch back to my F13 unless I switch to windows mode in my VirtualBox.
I've tried a new Ubuntu 10.04 and Fedora 13, both o them have gnome >= 2.30. In them, alsamixer says default sound device have only master volume slider. When I changed device to "Intel HDA ..." it shows all the sliders (Master, PCM and other). I saw changes in the default master volume causes changes in both, Master and PCM scales. Is there anyone know how to make gnome sound volume hotkeys leave the PCM slider alone? I need it for my personal tasks.
I'm using Glade and Anjuta to build an oscilloscope and wanted a dial like a real scope, so I sub classed a VScale and painted my own dial.In the process I lost the ability to move the dial.I' ll have to implement the interface from scratch like I started from a base Gtk::Widget.Is this the way it is, or are there ways to change visual appearance of the VScale and still keep it reacting as a VScale?
I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received: Login to your windows server and load the DHCP configuration screen Create a DHCP reservation for the MAC address you obtained Add the configuration options below to enable the machine to boot from the LTSP server 017 Root Path: /opt/ltsp/i386 066 Boot Server Host Name: <ip address> 067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'

I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?
