    My New Provider… SliceHost.com!

    July 1st, 2008

    I’ve been moving my blogs and the other’s I host through a lot of transitions lately after having a HORRIBLE experience with GoDaddy and then Compute Cycle concerns with Mosso.com.

    Mosso’s new compute cycles are heavily counting Wordpress and other DB driven site hits.  5 relatively low hit blogs, ~150,000 TOTAL hits, were taking up as many Compute Cycles as one of my non-DB driven sites getting > 2,500,000 hits with lots of graphics.

    I still like Mosso and most of my sites are still using email on them, but a bit more predictable monthly bill is nice.

    So I happened to run across SliceHost.com yesterday… The site is simple and clean and I was impressed at the speed of their own website. Some of the hosting providers I find while searching around have sluggish sites, which really makes me question their server/network capacity and so on.

    Here is their basic blurbage from the front page of their site.

    BUILT FOR DEVELOPERS

    We’re just like you. Sick of oversold, underperforming, ancient hosting companies. We took matters into our own hands. We built a hosting company for people who know their stuff. Give us a box, give us bandwidth, give us performance and we get to work. Fast machines, RAID-10 drives, Tier-1 bandwidth and root access. Managed with a customized Xen VPS backend to ensure that your resources are protected and guaranteed.

    • No contracts, no setup fees.
    • Upgrade, downgrade, add a slice or remove a slice anytime.
    • Billing is monthly, cancel at anytime.
    • Payments of $240 or more receive a 10% credit.
    • Full root access and rebooting
    • Choice of Linux distro
    • Dedicated IP address and Tier-1 redundant bandwidth
    • RAID-10 disk storage
    • Reserved RAM
    • Guaranteed CPU share and more when available
    • 4-core servers running Xen virtualization instances
    • Slicehost management portal for reboots and software installs
    • Mobile management portal for smartphones
    • Ajax console access
    • Bootable rescue mode
    • Machines running with fixed usage limits, below full capacity

    So I decided to go ahead and give them a try and signed up for a 256mb Ubuntu 8.04 Hardy “Slice”.  That slice is a virtual machine running on a nice large powerful server.  For $20/mo I get a VM with 256 RAM, 10GB space, 100GB bandwidth.

    Some may think that’s so little, but it’s plenty to run a quite a large handful of decent sized Wordpress blogs or other similiar CMS systems.  10gb is plenty for people who aren’t uploading massive uncompressed images, videos and other media.  100gb is also good especially if your web server is using mod_deflate to compress output.

    Provisioning only took like 5 minutes, it was assigned a static IP and a default (hard) random root password that I went in and changed to my harder password.

    I ran the apt-get install commands I used to get the lighttpd setup running on it like in my post back in April.

    Basically in about 30 mins I was setup, I went ahead and moved over idude.org here and then 5 of my other friend’s blogs and am in a “testing phase” now.

    Back to SliceHost…

    I really like their control panel, it is very simple and sweet and has pretty much everything you need to manage your VMs.  The backup is very simple and can be automated to daily as well as a weekly. These backups are FULL VM snapshots to take your entire machine back to a previous state.

    A Unique feature is an AJAX powered console to your server.  I don’t think it really full supports CTRL functions and stuff, but it’s enough to change some permissions, delete some stuff, create new folders, etc.

    If you outgrow the 256mb/10gb/100gb Slice, you can scale it up, without losing data and minimal downtime, up to a 4096mb/160gb/1600gb Slice, which is 16x the power/space at only 14x the cost.  ($280)

    There are also nice stats to show CPU use, CPU time, disk I/O, and network I/O.    You can do soft/hard reboots as well plus much more.

    A few months ago, I had a VM of about the same size at GoDaddy running CENTOS 4 (only Linux option at the time) and it was horribly sluggish and had all kinds of “default” crap on it.  This Ubuntu install on SliceHost is virtually a base install allowing me much more flexibility over what goes on it.

    The performance of it was also generally lightning fast.  I’ve used Ubuntu directly on a powerful server and it appeared just as responsive both in the console running commands and hitting the sites remotely.

    Network speed was excellent as well… Got 16mbps uploading some files to it, which again, isn’t bad for a VM.

    One last thing.  SliceHost is running out of St. Louis.  After pinging it from a web-based “multiping” site, it got excellent low latency from all parts of the country, as compared to hosts I’ve used on either the left or east coast, due to it’s central location.

    More updates will follow as more is experienced.  I think I’ve finally found a long term home for my Linux sites.

    Utilizing Akismet Spam Blocker in a PHP Contact Form

    May 14th, 2008

    I have a contact form on my company’s website that I have had serious problems with in the past… The past being before I implemented Akismet into the code.

    Akismet is a service provided by Automattic (the creators of Wordpress) and is an excellent API based spam blocking system. I’ve been using it for quite a while on my blog and rogue spams hardly EVER make it into my comments. Probably somewhere in the neighborhood of only 1-2 out of thousands make it through.

    I will post both the basic code for a contact form as well as the Akismet PHP5 Class (from Alex) and the include file I created to utilize the PHP5 Class.

    Here is the basic form (named contact.php), with the PHP code on top, that I use.

    <?php
    if ($_SERVER["REQUEST_METHOD"] == “POST”)
    {
    include ‘akismet.php’;

    $to = “YOUR EMAIL ADDRESS“;
    $subject = $_REQUEST["Subject"];
    $message = $_REQUEST["Message"].”<BR><BR>”.$_REQUEST["Phone"].”<BR>”.$_REQUEST["URL"];
    $from = $_REQUEST["Email"];

    $headers = ‘From:’.$from.”\r\n” .
    ‘X-Mailer: PHP/’ . phpversion() .”\r\n”.
    ‘Content-type: text/html’.”\r\n”.
    ‘Date: ‘.date(”r”).”\r\n”;

    mail($to, $subject, $message, $headers);

    echo “Message Sent!”;
    die();
    }
    ?>
    <html>
    <head>
    <title>My Contact Form</title>
    </head>
    <body>

    <form action=”contact.php” method=”POST”>
    <table align=”left”>
    <tr>
    <td align=”right”>Your name:</td>
    <td><input name=”Name” type=”text”></td>
    </tr>
    <tr>
    <td align=”right”>Website:</td>
    <td><input name=”URL” type=”text”></td>
    </tr>
    <tr>
    <td align=”right”>Your email:</td>
    <td><input name=”Email” type=”text”></td>
    </tr>
    <tr>
    <td align=”right”>Subject:</td>
    <td><input name=”Subject” type=”text”></td>
    </tr>
    <tr>
    <td align=”right”>Message:</td>
    <td><textarea name=”Message” style=”width: 224px; height: 83px”></textarea></td>
    </tr>
    <tr>
    <td align=”right”>Your phone:</td>
    <td><input name=”Phone” type=”text”>(Optional)</td>
    </tr>

    <tr>
    <td> </td>
    <td><input name=”Submit” type=”submit” value=”submit”></td>
    </tr>
    </table>
    </form>

    </body>
    </html>

    contact.php includes the code I created to use the Akismet PHP5 Class mentioned earlier.

    Here is the code for the akismet.php. Be sure to change the $WebsiteURL variable to your website address and $APIKey variable to the API key you already have. If you do not have one, signup for a Wordpress.com account and you can get one free.

    <?php
    //Akisment PHP5 Class from Alex (http://www.achingbrain.net/stuff/php/akismet)
    include ‘Akismet.class.php’;

    //ENTER YOUR API KEY ON THE LINE BELOW!
    $APIKey = ‘YOUR_API_KEY‘;

    //Enter your web site address below. This is used as a parameter in the API call to Akismet…
    $WebsiteURL = ‘YOUR_WEBSITE_ADDRESS‘;

    //Call to check for valid API Key…
    $akismet = new Akismet($WebsiteURL, $APIKey);

    //Check to see if your API key is valid, if not, it will tell you so and stop.

    if($akismet->isKeyValid()) {}else{echo “Your API key is NOT valid!”;die();}

    if ($_SERVER["REQUEST_METHOD"] == “POST”) {

    //CHANGE the $_REQUEST items to match your form field input element names

    $akismet = new Akismet($WebsiteURL, $APIKey); //
    $akismet->setCommentAuthor($_REQUEST["Name"]);
    $akismet->setCommentAuthorEmail($_REQUEST["Email"]);
    $akismet->setCommentAuthorURL($_REQUEST["URL"]);
    $akismet->setCommentContent($_REQUEST["Message"]);
    $akismet->setPermalink($_SERVER["HTTP_REFERER"]);

    //IF THE MESSAGE IS FOUND TO BE SPAM, A MESSAGE WILL BE DISPLAYED. Customize as needed.

    if($akismet->isCommentSpam()) {
    echo “For some reason, your message was flagged as a possible SPAM message.”;
    die();
    }
    //IF THE MESSAGE MAKES IT TO THIS POINT, IT IS VALID AND THE SCRIPT THAT CALLED THIS
    //FILE WILL CONTINUE PROCESSING THE INPUT ACCORDINGLY…

    }
    ?>

    My first look at Ubuntu 8.04 LTS as a Desktop and Server

    April 28th, 2008

    Last week, after much waiting by myself, Ubuntu 8.04 LTS came out. Before the release, I didn’t have the time to really mess around much with the BETAs or the last Release Candidate, but the morning it was released, torrenting commenced and went to work.

    Got home, burned it to a CD and installed it on my primary Windows workstation (running Vista) using the Wubi Installer.

    For those of you not familiar with Wubi, here is the blurb from their website:

    “Wubi is an officially supported Ubuntu installer for Windows users that can bring you to the Linux world with a single click. Wubi allows you to install and uninstall Ubuntu as any other Windows application, in a simple and safe way. Are you curious about Linux and Ubuntu? Trying them out has never been easier!”

    So basically, you can install Ubuntu into C:\ubuntu then when rebooting your machine, you will have another option to boot to besides Windows… The Wubi Installer by default only created a 12gb “container” for the Ubuntu installation. If you plan on actively using Ubuntu under Wubi, make it as large as you can do without, space wise, in Windows. It can get a bit geeky to add more space to the Wubi side after the fact. I didn’t realize it at the time and went with the 12gb, but then I wanted to run XP inside a Virtual Machine, which didn’t leave me much space left. I ended up Googling around and found a method to create a second Wubi disk and copy over your /home/ folder to it and changing your fstab to use it. So I had the 12gb for system stuff and another separate 25gb /home/ disk image.

    The best thing about Wubi is that it allows you to test out Ubuntu on your machine without wiping out anything, no re-partitioning, no real impact on your system at all. You do take a slight performance hit since you are running this off a file on the NTFS file system, but the hit isn’t anywhere near as much as running it from VMWare, which doesn’t help if you are looking to see if Ubuntu is truly compatible with your hardware.

    First Install as Desktop

    Here are my basic system specs of my first install:

    Lenovo something…
    AMD 64 X2 3800+
    2048mb RAM
    250gb HDD
    nVidia GeForce 8600GT XFX XXX w/ 256mb RAM
    22″ Samsung wide screen @ 1680×1050
    19″ Samsung @ 1280×1024

    The installation was a breeze and all I had to do was set my network information to get online (I don’t use DHCP on my router).

    The nVidia “restricted” driver took a few minutes to download and install due to the mass deluge of downloaders hitting Ubuntu’s (and mirror) servers. Response time for all APT-GET queries were a bit slow over the weekend. It calmed down some on Sunday and I was able to get things done quickly.

    Setting up the Beryl/XGL effects were easy once the aforementioned driver was enabled, but Ubuntu leaves out the “advanced” configuration options for the effects. Again, googling around, I was able to find the “apt-get” commands to get those utilities installed.

    Probably the longest thing to get working was the true dual display.

    Just after installing Ubuntu, both monitors had the same output. After installing the nVidia drivers, the secondary screen dropped out, but there was no explanation for it and no setting in the display properties would bring it back. Googling mentioned a program called “nvidia-settings” which I ran and after much tinkering was able to get a solid xorg.conf created to have the 22″ monitor primary and the 19″ as a secondary span to the first.

    Needing to work a lot in the Windows world, I keep a Raw XP VM Machine around that is patched (mostly) and ready to unzip and load to install the few Windows based utilities I need like Adobe Photoshop (doesn’t work well under Wine) and Microsoft Expressions/Visual Studio. Installing VMWare Player took a bit of hacking around, but installed fine. I used the secondary monitor to full screen XP while keeping Ubuntu on the primary.

    Overall, things are MUCH better under 8.04 than any of the previous Ubuntus in my opinion. Googling around for things was key for me. Be sure to include “8.04″ in your search queries to limit the number of older pages from being returned. Some of those instructions are way out of date with 8.04.

    Later this week, I am going to try my “dad test” on Ubuntu to see if he can handle it, I did install it on his machine, but had trouble getting his Wireless to connect to one of my many access points (He lives across the street with a WiFi repeater in his office). I think the driver is just flaky.

    Might end up just putting an Ethernet bridge on his PC so it’ll just use his ethernet port which looked fine.

    Second Install as Server

    System Specs:
    Dell SC430 Server
    Intel Pentium D Dual Core 2.8ghz
    1gb RAM
    160gb SATA HDD
    Integrated Video
    17″ Viewsonic LCD

    As has been usual with the later Ubuntu builds, Installation was a breeze. This time, I wiped out the parition completely and installed it directly on the box which made it very fast compared to the Wubi install above, which isn’t bad to begin with.

    For this installation, I was more server focused, but did not install the “server” version of Ubuntu. I opted to use the same “desktop” version and install all the packages I needed to make it a “server”.

    Doing a lot of Wordpress Installations, I chose to get a Virtual host WP environment setup.

    I’ve been hearing a lot of good about LighttpD lately and decided to apt-get that instead of Apache2.

    LighttpD is a VERY fast alternative to Apache2 (up to 50% faster in some cases). Setting it up was as easy as “apt-get install lighttpd” (After removing Apache2).

    # apt-get remove apache2.2-common
    # apt-get install lighttpd mysql-server php5-cgi php5-mysql

    I also grabbed PHP-CGI and did a little tweaking to get lighttpd to parse the PHP files using FastCGI which was not difficult.

    # lighty-enable-mod fastcgi

    Had to edit the /etc/lighttpd/conf-enabled/10-fastcgi.conf to get my paths correct.

    Googling around gave me the conf file lines I needed for the Virtual host config:

    For a single hostname like yourdomain.com

    $HTTP["host"] == “yourdomain.com” {
    server.document-root = “/your/www/path”
    }

    for anything.yourdomain.com use this…

    $HTTP["host"] =~ “(^|\.)yourdomain\.com$” {
    server.document-root = “/your/www/path”
    }

    Put as many as you need in there. I used a spare domain and pointed *.MyDomain.com over to it and setup a few virtual hosts to test them.

    Restart Lighttpd using:

    /etc/init.d/lighttpd force-reload

    I had a LLMP (Linux, Lighttpd, MySQL, PHP) server setup and ready to go.

    Download the latest WP files:

    curl http://wordpress.org/latest.tar.gz -o latest.tar.gz

    Uncompress them to the virt root of your choice and be sure to chmod the folders correctly so WP can run the setup and create the wp-config.php file.

    To make Permalinks (friendly URLs) work, just add this into the lighttpd.conf before (or within) the virtual host directives…

    server.error-handler-404 = "/index.php"

    This will allow the permalinks to work correctly, mod_rewrite rules are not necessary.

    There may be a little more to all this than the above instructions, depending on your configuration. The information provided was to just provide basic guidance.

    My plans are to eventually backup all the WP blogs on host on my dedicated server and curl them over to this Ubuntu box, uncompress them, drop and restore the databases and have a mirror of them offsite from the dedicated server in case anything ever happens. This should be easiest enough to do in a few hours in one script file on the server to do the backups and database dumps into one compressed file, then another cron’ed script on the local Ubuntu to curl it down and restore everything. If anything ever goes wrong, just change the DNS for the domains and point them to my local Ubuntu which can be DMZed on my router. :-)


    Wordpress 2.5 Image Insertion Problem

    April 6th, 2008

    I know MANY people have reported problems with the new 2.5 Wordpress, especially in the backend administration portion.

    The only problem I’ve personally run into so far is inserting images into a post after uploading it. The upload portion including the new flash uploader works flawlessly for me, then when I hit “Insert” to put it in the post, the “Add an Image” popup would just go blank and sit there forever. I tried various things including disabling all plugins, manually updating the files in the wp-admin and wp-includes folder to no avail.

    Here is how I fixed my installation…

    I simply reinstalled it using the following steps…

    • Backup blog and database… (ZIPped up blog and MySQL Admin backed up database)
    • Used Wordpress Export to export settings, articles, comments etc. for reimportation after reinstall
    • Clear out the blog web root and delete all content in the database leaving it blank.
    • Dropped new WP 2.5 files into the root and went through the install process for the new blog
    • Reimported the XML file with the settings, articles, etc…
    • Made sure my other settings like Permalinks were still setup correctly
    • Copied over my themes, plugins and uploads folder so I wouldn’t have broken links and reactivated my plugins and theme.

    The only thing that I can see that didn’t reimport back over was my blogroll links. To fix this, I went ahead and restored my old database and ran this SQL command… from the commandline.

    insert into idude.wp_links select * from idude_OLD.wp_links;

    Looks like everything is back up and running for me, and it only took about 10 minutes.
