VPSLatch VPS Benchmark

Asim Zeeshan — Sat, 28 Aug 2010 00:38:53 +0000

Unix Benchmark results from VPSLatch (OpenVZ running Ubuntu 10.04 LTS 32bit on their Orlando, FL node) using unixbench v 5.1.2

Specs: 1024MB / 60GB OpenVZ running Ubuntu 10.04 LTS 32bit

Note: This VPS has the best benchmark that I have ever seen, wow, no doubt Adam is having busy managing the best VPS+CPanel combination ever!

Spacerich VPS Benchmark

Asim Zeeshan — Sat, 14 Aug 2010 11:50:05 +0000

Update (26-Aug-2010): From my experience, they have very huge iowait and hence I/O problems on their VPS servers. You have to wait for like 10-15 seconds for a ‘uptime’ command to execute which is pretty pathetic. So in my opinion, it was useless for me.

Unix Benchmark results from Spacerich (OpenVZ running Ubuntu 10.04 LTS 32bit on their Munich, Germany node) using unixbench v 5.1.2

Specs: 256MB / 25GB OpenVZ running Ubuntu 10.04 LTS 32bit

Note: Being in Europe, it has the best response time to Asia especially Pakistan

Not getting a package on Ubuntu?

Asim Zeeshan — Sat, 24 Jul 2010 19:00:58 +0000

If you are not getting a package on Ubunu using apt-get then chances are that it has not been updated in the /etc/apt/sources.list file

For example, the following should be there in the sources.list file if you are running Ubuntu 10.04 LTS (codename lucid)

Installing Lighttpd, PHP and MySQL on Ubuntu

Asim Zeeshan — Mon, 19 Jul 2010 13:22:38 +0000

If you are not getting a package on Ubuntu, please check to see if your /etc/apt/sources.list file is updated. This is common with most VPS providers

On VPS, especially with challenging small memory limit (e.g. 64MB or 128MB) lighttpd is the best option instead of Apache. In this article I will show you how to do that. On a fresh box (which has no apache installed) type this to get lighttpd webserver installed

apt-get install lighttpd

Now install PHP5 CGI package and PHP5 command line package

apt-get install php5-cgi php5-cli

Edit the following file

nano /etc/php5/cgi/php.ini

and uncomment this line

cgi.fix_pathinfo = 1

Now enable fastcgi module

lighty-enable-mod fastcgi

Restart Lighttpd

/etc/init.d/lighttpd restart

You get the welcome page

Lets install MySQL 5.1 server and client

apt-get install mysql-server mysql-client

and optionally phpMyAdmin

apt-get install phpmyadmin

Now create a test page to see if phpinfo is all Ok

nano /var/www/info.php

Type in the following

PHP Depreciated errors on Ubuntu 10.04 LTS

Asim Zeeshan — Sun, 20 Jun 2010 20:01:51 +0000

If you have installed LAMP (Apache, MySQL and PHP on Ubuntu 10.04 LTS) then running this on SSH

php -v

would be giving you certain PHP Depreciated warning like these

root@sea:~# php -v
PHP Deprecated:  Comments starting with '#' are deprecated in /etc/php5/cli/conf.d/idn.ini on line 1 in Unknown on line 0
PHP Deprecated:  Comments starting with '#' are deprecated in /etc/php5/cli/conf.d/imagick.ini on line 1 in Unknown on line 0
PHP Deprecated:  Comments starting with '#' are deprecated in /etc/php5/cli/conf.d/imap.ini on line 1 in Unknown on line 0
PHP Deprecated:  Comments starting with '#' are deprecated in /etc/php5/cli/conf.d/mcrypt.ini on line 1 in Unknown on line 0
PHP 5.3.2-1ubuntu4 with Suhosin-Patch (cli) (built: Apr  9 2010 08:23:39)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies

Its a noted bug with Ubuntu and changes may be pushed soon but to fix this just edit each of these files and replace comments starting with ‘#‘ to ‘;‘.

Install PHP5 ADOdb extension on Ubuntu

Asim Zeeshan — Sun, 30 May 2010 05:00:37 +0000

ADOdb library is a very good data abstraction layer for PHP. Installing a PHP extension enables the library to auto-detect this and give even better performance. To install this library on Ubuntu 10.04 LTS do this

apt-get install php5-adodb

Installing PHP’s SSH2 extension on Ubuntu

Asim Zeeshan — Thu, 27 May 2010 16:18:45 +0000

On Ubuntu 10.04 LTS, Do this (there’s no need to do any compiling anymore)

apt-get install libssh2-1-dev libssh2-php

You can now test if PHP recognizes it’s new ssh2 extension by running:

php -m |grep ssh2

Don’t forget to restart Apache

service apache2 restart

Good bye CentOS! Hello Ubuntu

Its been about almost more then two years since I have been playing with CentOS on many different platforms etc. Its very stable but on the other hand, PHP/MySQL updates are very hard to get and still PHP is 5.1.6. I tried EPEL repo and it updated PHP to 5.3.1 but still there were conflicts with stuff and many core packages.

So, I thought why not move to Ubuntu since it has just announced 10.04LTS (Long Term Support) in April 2010. Folks at iWeb were really nice to do a reinstall without any charges and also process a memory upgrade request at an amazing 50% discount.

Ubuntu 10.04 LTS

Apache 2 version is 2.2.14
PHP version is 5.3.2
MySQL version is 5.1.41-3ubuntu12
SVN (Subversion) version is 1.6.6

As a comparison CentOS 5.4 has the following versions

Apache 2 version is 2.2.3
PHP version is 5.1.6
MySQL version is 5.0.77
SVN (Subversion) version is 1.4.2

So if you are a PHP developer looking to deploy a Linux flavour on your new box, choose Ubuntu
