Installing MySQL 5.1 on Ubuntu

I wanted to use PARTITIONING introduced in MySQL 5.1 to handle some 2 Million records (and growing everyday) in a table. Ubuntu 8.10 does not have MySQL 5.1 available if you do apt-get the latest version available is 5.0

So this is what I did, its easy and this might help somebody.

nano /etc/apt/sources.list

I prefer nano editor but you can use any editor of your choice. Add these new lines at the end of the end of the file.

deb http://ppa.launchpad.net/monty/ubuntu gutsy main universe restricted multiverse
deb http://ppa.launchpad.net/smurf/ubuntu gutsy main universe restricted multiverse

(These packages were targeted for 7.10 so I will recommend using them and removing them from this list once you got the latest MySQL version)

Now run the following commands

apt-get update
apt-get upgrade

Note that you may need to do sudo prefix to these commands if you are using a non-root account. Now lets do the one last step, Installing MySQL 5.1

apt-get install mysql-server-5.1

Update: I have got another source to get even latest minor version of MySQL 5.1, just follow the above steps, then start over again and add following lines to “/etc/apt/sources.list” instead of the one above.

deb http://packages.dotdeb.org stable all
deb-src http://packages.dotdeb.org stable all

It worked for me on Ubuntu 8.10, im sure it will work for just any server version.

I am not a linux guru so if someone has a better option to upgrade to MySQL 5.1 or the latest version, please let me know.

Ubuntu: Setting default gateway / ip etc

If you want to specify a default gateway or ip address for your Ubuntu installation, try the following steps.

Open SSH and type this command

sudo nano /etc/network/interfaces

You can edit everything there as shown in the screenshot below (click to enlarge)

Ubuntu network interface

auto eth0
iface eth0 inet static
        address 192.168.1.231
        netmask 255.255.255.0
        network 192.168.1.0
        broadcast 192.168.1.255
        gateway 192.168.1.77
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 192.168.1.253 192.168.1.226

Intall Apache, MySQL and PHP on Ubuntu 8.10

WARNING: Please use this method to install Apache, PHP and MySQL because its more suitable for most of your needs and has options to auto-upgrade your installation. The following method is obsolete and not recommended.

After trying to install Apache, MySQL and PHP on Ubuntu 8.10 via several methods listed over the web. I opted for xampp package for linux.

It is as easy as ABC

Download the xampp linux package from their official website

wget http://nchc.dl.sourceforge.net/sourceforge/xampp/xampp-linux-1.7.tar.gz

(I have selected NCHC, Taiwan as the mirror to download this package, you may try another)

Extract the files

sudo tar xvfz xampp-linux-1.7.tar.gz -C /opt

Chmod the files to have nobody ownership

sudo chown -R nobody:root /opt/lampp/

Configure xampp security

sudo /opt/lampp/lampp security

Start xampp with this command

sudo /opt/lampp/lampp start

Stop xampp

sudo /opt/lampp/lampp stop

Restart xampp

sudo /opt/lampp/lampp restart

Login to ftp using the username nobody and the password that you have set up in the “xampp security”

To uninstall xampp

sudo rm -fr /opt/lampp

Enjoy!!

Download files from a http authenticated directory using wget

I wanted to download something off a sub-domain using wget that I have password protected using .htaccess
so the following command was NOT working

wget http://secure.asim.pk/myfiles.tar 

Luckily, we can pass two arguments to the same command and tell wget what the username and password is

wget http://secure.asim.pk/myfiles.tar --http-user=myuser --http-password=mypass 

Works Great!!

If you are using Ubuntu 8.10, have not enabled root user and trying to download to a directory that has “nobody” or “root” as owner then try pre-pending it with sudo

sudo wget http://secure.asim.pk/myfiles.tar --http-user=myuser --http-password=mypass 

How to Install Webmin in Ubuntu

From the little help that I can get over the internet, I found out that you need to install the following packages to prepare the system for Webmin installation.

Run the following command over SSH or Ubuntu Desktop’s terminal window (Applications -> Accessories -> Terminal).

sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl 

(Learn how to configure SSH on Ubuntu 8.10 if you want to have a remote access to your Ubuntu box).

Download the latest version of Webmin by running the following command (visit webmin download section for newer versions)

wget http://ignum.dl.sourceforge.net/project/webadmin/webmin/1.500/webmin_1.500_all.deb 

Downloading Webmin
Downloading Webmin

After the package has been downloaded, run the following command to install it

sudo dpkg -i webmin_1.500_all.deb 

You should now be able to login to Webmin at the URL https://localhost:10000/ using root or any other user with sudo access.

Configuring SSH on Ubuntu 8.10

The first issue that I had after installing Ubuntu 8.10 was that I could not connect to SSH on it because SSH server is not installed on Ubuntu 8.10 and it never asked me if I wanted to make a selection of what software packages I need to have installed. I guess thats why they are making a less then 25 min install promise.

Here’s how you can enable / configure / install SSH on your Ubuntu 8.10
Open a terminal window by selecting the Applications menu and selecting Terminal from the Accessories menu. In the terminal window enter the following command and press enter to execute it

sudo apt-get install openssh-server

It will automatically download and install the SSH serve and configure it to run on port 22 (default port).

I will write another article to explain how you can change the port or enable / disable the SSH server.

Ubuntu 8.10, Perfect Linux distro for PHP development

I recently felt the urge to have a development testing environment on Linux (LAMP). I tried CentOS first since it is one of the leading industry standard Linux server. I was disappointed to see that CentOS does not have a 5.2.x series of PHP that I could install via “yum” (am not a very advance user so does not wanted to build it by typing long queries in SSH just to find out that I left some core thing in the first place).

I did a bit of research and found out that Ubuntu could be a better choice. Luckily I had the latest version of Ubuntu already shipped via Postal Mail (aka Snail Mail) and this time the CDs DID get through the customs.

For those new to Ubuntu, you can either download it or request FREE cds from Shipit.Ubuntu.com.

Ubuntu 8.10, the latest release, is a breeze to install and start running. I used VMWare Workstation to run it on my Windows installation.
