[solved] MySQL server not Starting


MAMP headache on Mac

If you can’t figure out why the MySQL Server won’t turn on if you’re using MAMP to do local development work, here are two ways to go about it.


What worked for me

  1. Quit MAMP.

2. In the Finder, go to and delete the log files (in my case ib_logfile0 and ib_logfile1).


3. Restart MAMP.

So I tried the below fix and kept getting

No matching processes were found

What others used that didn’t work for me

Quit MAMP.

  1. Open Terminal (either open Spotlight (Cmd+Space) and type “terminal” or you can find Terminal in the /Applications/Utilities/folder)
  2. Then type this (will allow you to kill the mysqld process with security privileges of another users such as root)
ps aux | grep mysql 
lsof -i 
sudo killall -9 mysqld

4. Restart MAMP

Happy Developer!!

How to Solve WordPress Could Not Create Directory


WordPress is an interesting platform to build your website but when you get this kind of errors, you feel like plucking your hair off your head because nothing is happening. I have tried like 10 solutions but never got it right until now.

Am sure you have gotten something like this when trying to update your plugin or upgrading WordPress.

This is the error for the Upgrading of WordPress

Downloading update from http://wordpress.org/wordpress-4.4.zip…

Unpacking the update…

Could not create directory.

Installation Failed

This is the error for the plugin update

  Downloading update from http://downloads.wordpress.org/plugin/your-plugin.…

  Unpacking the update…

  Could not create directory. /wp-content/upgrade/yourplugin.tmp
  Return to Plugins page

Step 1:

Plugin: Just change the permission of /public_html/wp-content and /public_html/wp-content/plugins to 775. If the update succeed just revert it back to its default permission.

Upgrading: Just change the permission of /public_html/wp-content and /public_html/wp-content/upgrade to 775. If the upgrade succeed just revert it back to its default permission.

chmod 775 /var/www/html/wordpress/wp-content/

chmod 775 /var/www/html/wordpress/wp-content/plugins

chmod 775 /var/www/html/wordpress/wp-content/upgrade

Step 2:

Add the proper group permissions most likely to the same that Apache is running under.

ps aux | grep apache 

You will see the Apache user group on the left.

See my example of how I did it:

Step 3:

Now change your WordPress folder to the same user group, you can do this in a parent folder or sub folder but for sanity it usually best for parent folder, use -R to recursively do it.

chown -R apache:apache /path/to/wp-root-folder
  • To login on windows use Putty
  • Enter your hostname and port
  • Choose connection type depending on server settings
  • Click open

If you try to chown and get denied you will need root privileges , type sudo su and your password.

Now try updating the plugin or Upgrading WordPress.

Awesome!!! Now we have solved that issue.

Finding a computer’s model using command prompt & terminal


May be you want to find out the drivers for your PC and you need to be specific, you have to have the model of your PC. It’s fairly simple.

A. On Windows Command Prompt:

On my machine that returns two lines, one saying Name and another with my machine’s model name:

Dell Inspiron 15 N5040

Now that’s cool!!

B. For Linux Terminal:

sudo dmidecode | grep -A3 '^System Information'


This is what you get:

“Open In Terminal” action in Ubuntu 14.04


When I was installing Whatsapp on my Ubuntu PC, there was a step where I had to “Open in Terminal” but my Ubuntu 14.04 had no such option, so I did some digging and this is how you do it.

nautilus-open-terminal and nautilus-actions packages are available in Universe repository of Ubuntu 14.04. So run the below commands to enable universe repository and also to install above mentioned packages.

sudo add-apt-repository universe
sudo apt-get update
sudo apt-get install nautilus-open-terminal
sudo apt-get install nautilus-actions

Finally run

nautilus -q

command to quit nautilus. Now you can be able to see Open in terminal option on right-clicking.

Hope that helps.
