  • MySQL Daemon failed to start.

    - by matthewsteiner
    There were no updates when I ran yum update. I was trying to install php-soap (which was failing), and online I found I should run this: wget -q -O - http://www.atomicorp.com/installers/atomic.sh |sh After running that, then "yum install php-soap" ran successfuly. Then I ran yum update just to check for updates and said yes for some packages. I noticed there were some mysql ones and such. Now mysql isn't running anymore and it won't let me start it (I get "MySQL Daemon failed to start") Ideas?

  • Understanding this error: apr_socket_recv: Connection reset by peer (104)

    - by matthewsteiner
    So, if I do some benchmarking with apache benchmark (ab), and I use large numbers of requests. Then sometimes in the middle of a test I get this error. I don't even know what it means. So how can I fix it? Or is it just something that will happen if the server gets too many hits anyway? The problem is, if I run 10,000 hits, it'll all run perfectly. If I run it again, it'll get to 4000 and get the error: apr_socket_recv: Connection reset by peer (104) A little about my setup: I have nginx taking static requests and processing dynamic ones to apache. The file in question is served from cache by nginx, so I guess it's probably got to do with how nginx is handling the requests? Ideas?

  • How accurate is apache benchmark?

    - by matthewsteiner
    Alright, so I'm in development right now and I'd like to understand exactly how good the benchmarks are. I've just been using apache benchmark. Do they include the server sending the files? Also, is "requests per second" literally how many users can visit the page within one second? If it's at 30 requests per second, can literally 30 people be refreshing pages every second and the server will be fine? It seems like a lot to me. I know a lot of people get way better stats out of their servers, but I haven't done much optimization yet. Also, will increasing your ram increase you rps linearly? I have 512mb, so if I upgrade to 1gb, would that mean I'd get about 60 rps? How does concurrency affect your rps?

  • APC (php accelerator). What situations should I use this?

    - by matthewsteiner
    So I've just got a small vps. I've installed apc, which sped up normal pages by 20% - 30%. I was reading about memcached and came to the conclusion that I can use apc for the same thing (caching objects from database results) if I'm not distributing over other servers. Since I only have the one server, apc will be just as beneficial for caching things in memory. I'm still in development mode, and I'm sure it's hard to tell what would be best for production mode. The thing is, my database queries seem pretty fast (between .0008 and .02). None of my pages are way database intensive. Would it be beneficial to me to cache results in memory? If the database is running well right now, is it going to be having a hard time later? Also, is connecting to the database at all something that costs speed (even if I cache most of my queries, every page has to have a little database interaction for session data). So, basically if I have a limited ram, and one machine, will using apc rather than just letting the database be uncached be much faster? Ideas?

  • putty external text editor?

    - by matthewsteiner
    I'm new to ssh and linux in general. I've got putty set up and I can connect to my server and list files and everything. I'm wondering how I can edit a file using notepad++ (or another editor). Is there a way to have it automatically download and upload through ssh? How else do you edit a file? Thanks

  • nginx - proxy_pass is working - Apache isn't doing what it should...

    - by matthewsteiner
    So, I've got this in my nginx.conf: location ~* ^.+.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js)$ { root /var/www/vhosts/example.com/public/; access_log off; expires 30d; } location / { proxy_pass http://127.0.0.1:8080/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } So anything that is a "static file" that exists will just be done with nginx. Otherwise, it should pass it off to Apache. Right now, static files are working correctly. However, if something is passed to apache and it's example.com or subdomain.example.com, apache just spits out the "Apache 2 Test Page" that you get if there's nothing there. Apache worked fine before, so I'm guessing it has to do with the way nginx is "asking". I'm not sure though. Any ideas?

  • Change default directory structure in Plesk

    - by matthewsteiner
    So, I have an ftp account setup correctly and it connect just fine. However, when I go to the root directory of the website (I can see "httpdocs" and "conf" and other folders), I can't make a new directory or go into the "conf" directory. I'm sure I need to edit permissions, but how can I do that?

  • apache - subdomains are slower?

    - by matthewsteiner
    Using apache benchmark, I ran the exact same php application at my root domain and a subdomain. Even with multiple tests and high request numbers, the requests per second perform extremely differently. I mean something like this: example.com - 1200 requests per second bench.example.com - 50 requests per second What could be affecting this? These aren't using databases or anything, just mainly getting a simple page displaying. But it's the same app for both of them, and I'm wondering why they perform so differently. Ideas?

  • Nginx (for static files) and Apache (for dynamic content)?

    - by matthewsteiner
    So, my entire application runs on apache just fine. However, I want to test how much the requests per second increases if I put all static files through nginx instead. I found this thread: http://stackoverflow.com/questions/869001/how-to-serve-all-existing-static-files-directly-with-nginx-but-proxy-to-apache-t But I have a couple problems. I'm completely new to nginx, so I'm not sure where to put the configuration. (The file is at /etc/nginx/nginx.conf, but I don't know if I just add the code to the bottom or what?) Also, how can I have both servers running at the same time? Is it because they both listen on port 80? Right now I have to stop one to start the other, and that's as far as I've gotten. Thanks for any help.

  • reconfiguring php? or do I have to reinstall?

    - by matthewsteiner
    Alright, so I need the soap extension enabled in php. When I run phpinfo(), it's not there, so I'm guessing I have to recompile? I can follow tutorials online to recompile the most recent php version for centos, but will it generally just work after that? Or does apache need to know to use the new installation? Thanks for any direction you can give me.

  • AB failed requests - What can I do about them?

    - by matthewsteiner
    So, in the past I've never had any problems with this app. All benchmarks had 100% success rate. Yesterday I set up nginx to server static content and pass on other requests to apache. Now, if I have 1 concurrent user (-c 1) then everything is fine. But it seems the more concurrent users I have, the more failed requests I get. Not a lot, but maybe about 10 or 15 out of 350. They're "length", whatever that means. Visiting the website with a browser, I don't have any problems at all. How can I find out the cause of these failed requests?

  • I'm having a hard time choosing a hosting provider...

    - by matthewsteiner
    So, what hosts do you recommend? The problem is, I can't manage the server. I know there's options out there like slicehost and vps.net, but management doesn't come with those. All I need is a simple lamp stack that can easily scale. Stuff like cloud sites (rackspace) is too expensive (starts at $150/month). I only need something small for now. Suggestions?

  • jquery effects (show)

    - by matthewsteiner
    Is there a way to just have something "show"? I know there's the effect called show, but I mean something with no animation. I know I could make the speed way fast or something. Or I could change the css from hidden or something. But does someone know of a built in method that does that? Same with "hide".

  • jquery nodename returning undefined

    - by matthewsteiner
    This code isn't for anything in particular. I'm just trying to successfully get the tagName or nodeName of an element. However, when I run the following code, I always get an alert saying "undefined". I'm wondering if it's because this function executes when the document is ready? Is there a different place I should be doing this? Or is it probably my other javascript code conflicting somehow (I would doubt). $(document).ready(function(){ $('#first').hover(function() { alert($('#last').nodeName); }); });

  • Jquery - custom countdown

    - by matthewsteiner
    So I found this countdown at http://davidwalsh.name/jquery-countdown-plugin, I altered it a little bit: jQuery.fn.countDown = function(settings,to) { settings = jQuery.extend({ duration: 1000, startNumber: $(this).text(), endNumber: 0, callBack: function() { } }, settings); return this.each(function() { //where do we start? if(!to && to != settings.endNumber) { to = settings.startNumber; } //set the countdown to the starting number $(this).text(to); //loopage $(this).animate({ 'fontSize': settings.endFontSize },settings.duration,'',function() { if(to > settings.endNumber + 1) { $(this).text(to - 1).countDown(settings,to - 1); } else { settings.callBack(this); } }); }); }; Then I have this code: $(document).ready(function(){ $('.countdown').countDown({ callBack: function(me){ $(me).text('THIS IS THE TEXT'); } }); }); I don't mind taking everything out of the "animate" loop; I'd prefer that since nothing needs to be animated. (I don't need the font size to change). So everything's working to a point. I have a span with class countdown and whatever is in it when the page is refreshed goes down second by second. However, I need it to be formatted in M:S format. So, my two questions: 1) What can I use instead of animate to take care of the loop yet maintain the callback 2) How (where in the code should I) can I play with the time format? Thanks.

  • Jquery simplemodal close existing modal and open a new one?

    - by matthewsteiner
    Alright, so all modals already have an image at the top right to close them. How can I make additionally another anchor to do the same thing? I thought I could use the "closeClass" option which default to "simplemodal-close" and just add that class to an anchor, but it didn't have the desired effect. Is that what I'm supposed to do? Also, all modals will have a "contact us" link which should close it's own modal and open the contact modal. How can I wait until it is closed to open the next one? Ideas? $('a#ask').click(function(){ $.modal.close(function(){ }); $('#modal-contact').modal(); });

  • Does anchor href of an image make it download?

    - by matthewsteiner
    So I was using yslow for firefox and my page weight was way high. My page has a main product image and then maybe 10 thumbnails. If you click a thumbnail, the image opens up in a popup done through jquery. The problem is, yslow is listing even the targets of the thumbnails as part of the page weight, so I guess for some reason the images are downloading. For example, I have: <a class="group nyroModal" rel="lightbox-group" href="/upload/topview.jpg"> <img alt="thumbnail" src="/upload/thumb/t_topview.jpg" /> </a> Would this normal html cause the "upload/topview.jpg" to automatically download? Or is it the jquery plugin "nyroModal"? I'd rather the images didn't preload, that'd waste a lot of bandwidth. So my question is, does a browser automatically try to download image files that are in the href property of anchors, or is the plugin most likely causing this? Thanks for any direction you can give me.

  • SimpleModal and Jquery (How to do open and closing animations)?

    - by matthewsteiner
    http://www.ericmmartin.com/projects/simplemodal/ There's two examples near the bottom of the page that show how to either do open or closing animations. I'm pretty new to jquery. How can I declare both onOpen and onClose? (I've only been able to get one to work at a time. jQuery(function ($) { $('a.basic').click(function (e) { e.preventDefault(); $('#basic-modal-content').modal( { onClose: function (dialog) { dialog.container.fadeOut('slow', function () { }); } } ); }); }); Thanks for any help you can provide.

  • jquery waiting until function is done

    - by matthewsteiner
    So, I set the closing function for simple modal as follows: $.modal.defaults.onClose = function (dialog) { $.validationEngine.closePrompt(".formError",true); dialog.data.fadeOut('slow', function () {}); dialog.container.fadeOut('slow', function () {}); dialog.overlay.fadeOut('slow', function () { $.modal.close(); }); } The line where the validationengine closes prompts basically just makes some divs disappear. The problem is that I don't want things to start fading out until closePrompt() is complete. Is there a way to do that? Is the only way with a "callback"? I don't think it has that built in to the function. Any other way to do it?

  • jquery selectors (finding tag)

    - by matthewsteiner
    I'm sure this is simple, but I can't seem to figure it out. I need to be able to pass a function an element id, and know what element tag it is. For example: <a id="first"></a> <input id="last" /> If I know the id is "first", how can I get that the tag is "a"?
