Left Slicehost, joined Linode

I moved my sites (2 servers) from Slicehost to Linode due to no 32-bit support at Slicehost and am VERY happy with the service I am receiving from Linode.  They have been excellent at answering the few questions I had during setup and everything has been flawless ever since.  The 32bit Linodes have been running much more efficiently for me than the 64 bit.

Mosso CloudServers

Since moving, the other day Mosso came out with their “version” of Slicehost’s system running straight through the Mosso control panel.  I setup a small 256mb instance for .015 cents per hour (~10.95/mo) which is cheaper than SH, but it doesn’t include any bandwidth… Bandwidth is bill seperately at .22/gb out and .08/gb in.  Which isn’t too bad if you are a relatively low bandwidth user like I am, but it’s still only 256mb.

Also, Mosso’s DNS control panel is nowhere near as good as Slicehost’s, which is a big negative for me using them long term.  Even though I’m on Linode primarily now, I still keep a 256mb Slice active on Slicehost just for their DNS since it has a very nice web interface and there’s an iPhone App for Slicehost’s control panel, including DNS.

FSCKVPS.COM

Another new place I found is FSCKVPS.COM… They are a little “rougher around the edges” than the Slicehost or Linode offerings, but their prices are quite amazing. This is most likely due to this being a “totally unmanaged” service.  Basic tickets related to network uptime and machine uptime is supported, but other things probably are not.  FSCK is a subsidiary of a larger UK based provider VAServ/A2B2, so I feel better about them not being a “fly by night” company. (Of course not implying that Slicehost or Linode is)

I setup a 32bit 512mb VPS (1024 burstable) in their Atlanta, GA data center for only $9.95 with 50% off the first month to test it out.  The control panel runs on a non-standard port (8887) so if you have a firewall at work, you may have trouble getting into it.

The setup was painless, but defaulted to CentOS which I rebuilt into Ubuntu 8.04 (8.10 in 32bit was not available).  The image was “minimal”… Even the source.list for apt needed to have all the repos added to it to get all the updates (it only had 1).  I then proceeded to do all updates and upgraded to 8.10 via commandline.

I upgraded to 8.10 using the instructions here…

http://www.howtoforge.com/how-to-upgrade-ubuntu-8.04-to-ubuntu-8.10-desktop-and-server

As stated before, the memory use of the default image was only 10mb, here’s a screenshot of htop

A2B2′s dedicated U.S. Server pricing is also VERY nice…

Intel Core2Duo E8300
2×2.83GHz, 6MB L2 Cache CPU
4GB DDR2 RAM
2×250GB SATA-II Disk
2000GB Monthly Transfer
5 IP’s
Price: $109.00/month

Normally you’d have to pay at least twice this much for something like this.  I’d probably switch my windows server here if Windows 2003 server wasn’t $30 more per month.  It would be nice too if they offered a machine like this with half the specs (2gb RAM, 2x120gb HDD, etc) for half the price.  That’s more within my pricing sweet spot.

I’m gonna keep testing this VPS throughout the month and see how it holds up.

Over the last few weeks, I’ve done a lot of blogging on my new provider, Slicehost, and the steps I’m taking to move away from Windows Server hosting to the Linux platform, at least for my personal sites and client development.  I still have to use some Microsoft technologies at my day job, but I am even in the queue to switch to Linux on my workstation at work too as new machines get ordered.  I plan on running XP in a VM for necessary things on the new workstation.

Well, so far with Slicehost, I’m now up to 3 Slices.  The 512mb one for the websites, a 256mb for development which will turn into another webserver once the 512 is “full”, and now a new 256mb one as a mail server.  I found a good tutorial on how to setup Postfix, Courier, MySQL & Squirrelmail with Spam Assassin and ClamAV in a multi-domain virtualized setup. (LINK)

This took a few hours to get working as intended, there were a few minor details missing, but I was able to track them down and get it working.  Most of it was just copying and pasting commands and changing a few details to my configuration.

The only part I really changed during this installation is NOT to use Spam Assassin and ClamAV, at least for the near term.  Both of these programs take up large amounts of RAM even with the base setup.  With the 256mb Slice, it was going into the swap memory as soon as I booted up and accessed anything.  Without these programs and with a bit of Apache tweaking, I got the memory down to around 116mb while idle.

Also, instead of SquirrelMail, which is “ugly” compared to modern web interfaces, I chose Roundcube, which has really gotten better over the last year.  It is still simplistic, but is very nice and functional.  With my setup, any email user just logs into the Roundcube interface with their email address and password.

Since all the usernames/passwords for this mail server are stored in the database, I was able to quickly write up a little PHP web interface to add/remove/modify email accounts and domains.  Once it is more stable to functional, I will release it here on this blog for others who have a similar setup.

As a test, I’ve been forwarding all my email on my primary account to a test account on this new server and every email has been received properly.  No problems whatsoever.

I plan on moving a few of my friends and family onto this to see how it works for them, if good, then all my customers will be migrated.

I have, for years, been developing web apps and so on using ASP (Classic) on IIS.  It’s a “fine” platform, but I have, over time, become weary of the Microsoft bloat that accompanies running a Windows Server… Especially in a colo/dedicated/VPS environment.

Over the last few months, since my major GoDaddy Windows Dedicated servers got hit by a worm or something, I’ve seriously started learning PHP with MySQL.  I used MySQL quite a bit with ASP and am quite familiar with it, but PHP experience was rather limited.  In the last few weeks, I’ve written a few things and ported a customer’s website over from an ASP CMS I wrote to PHP (still need to finish the CMS in PHP).  The site runs so much faster and I am now able to host it on my new Slice VPS that I setup earlier this month.  In 15 minutes or so, I can have an entire new Slice setup with Apache or Lighttpd and PHP/MySQL and, with a little tweaking and securing, have a server up and serving sites.   Can’t do that with Windows that quickly.

Slice is still running strong and I’m going to do my best to get ALL my ASP sites “ported” over to PHP over the next few months.  I’ve been using ASP/PHP cross reference sites like Design 215 and a few others and have been able to do things very quickly.  The database part was the only part I really needed to find good samples  for, but they aren’t even too hard once you use them a few times.

SliceHost has inspired me to really learn Linux and abandon the Microsoft OS, but there is still one caveat to Linux that I am very disappointed with.  There is not a single (that I’ve found), reasonably priced, multi-domain, domain level administratable email server with a nice webmail interface for users and administrative functions.

I know there are a ton of “pieces” that I can put together to get something like that, like Postfix, EXIM4, Dovecat, etc., but I just simply don’t have the time to wade through the massive pile of config files to get all those pieces working together in a nice secure and highly reliable fashion.

So, I am going to continue moving all my websites over to Linux/Apache/Lighttpd/PHP/MySQL and keep a small (30gb, 768mb RAM) Windows Virtual Dedicated server running with SmarterMail 5.x mail server on it. SmarterMail is probably one of the BEST email servers for a web hosting environment.  It is a snap to setup, backup and move to a new server if needed (Trust me, I know!). I already own an Enterprise license and am just waiting for one last very important domain to move off a temporary dedicated server before I move it to a new Windows VPS to serve the remainder of my customer’s email needs.  SliceHost isn’t a fully “managed” solution, but with the Slice Backup capability, you can have daily and weekly images made and restore to them quickly at anytime in case anything happens…

Mosso is good and is finally rectifying the Compute Cycle issue I mentioned previously,  I may keep them if I can break even with the few sites I still host on there, but their servers aren’t nearly as responsive as a VPS or Dedicated server probably due to the massively clustered setup they run.  I don’t really need individual site scalability… If a site has high requirements, I’ll just stick them on a new slice and charge the customer accordingly.  Most of my sites that would need to scale are WordPress Blogs and could easily handle being Digg’ed etc, by installing WP-Supercache.

Ultimately I plan on hosting all websites and blogs on Ubuntu 8.04 @ SliceHost and email on a Windows VPS @ GoDaddy (for now) until I find a Windows VPS provider as excellent as SliceHost is (hint hint to SliceHost)…

That’s all for now…

If anyone knows of any turn-key type mail servers that are free/inexpensive (< $500) for Linux please leave a comment.

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. :-)
