to lock your resolv.conf

Bug Description

Binary package hint: network-manager

This bug causes name resolution to be painfully slow. If I manually remove the routers ip from resolv.conf it works normally, but next time the machine is booted the address gets added to the list again. (more…)

Note: In this post I’ll be showing how to install Apache, php, MySQL and phpMyAdmin (one by one) on Ubuntu 8.10 using Terminal. If you want to install them all at the same time with minimal fuss, I recommend you to read my post on installing LAMP.]

Installing Apache

1. Open Terminal (Application -> Accessories -> Terminal) and execute the following command:

sudo apt-get install apache2

2. When the setup is complete you can check if the Apache is working properly by pointing your browser to http://localhost. If you see the text “It works!”, it means Apache is working just fine.

3. Towards the end of the installation if you see a message like this inside Terminal, “Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName“, you can fix this by executing the following command. It will open Gedit (text editor).

gksu gedit /etc/apache2/conf.d/fqdn

4. When Gedit opens, type “ServerName localhost” inside the file and click Save. Then close the file.

Installing php5

1. Inside Terminal, execute the following command:

sudo apt-get install php5 libapache2-mod-php5

2. When setup is complete, you have to restart Apache so that php5 will work on Apache. Execute the following command in Terminal:

sudo /etc/init.d/apache2 restart (more…)

Make Yakuake autostart:

Open up your home folder; make sure you can see your hidden files.
Navigate to the .kde/Autostart folder and create a new text file: yakuake.
Paste this in the file:

#!/bin/bash
/usr/bin/yakuake

Start up your new Yakuake Terminal and press F12.

~/.kde/Autostart/
chmod +x yakuake

Next time you start Ubuntu Yakuake will be running. You just need to press F12 to access it.
To configure it you can right click on the Yakuake screen and use the menu.
The size of the window and other settings can be accessed by clicking the small down arrow at the bottom right of the screen.

if you get an error like this: Fatal error: Allowed memory size wp-settings.php on line 307

The chkconfig command can also be used to activate and deactivate services. If you use the chkconfig –list command, you will see a list of system services and whether they are started (on) or stopped (off) in runlevels 0-6 (at the end of the list, you will see a section for the services managed by xinetd.
