– too much IO stats? IO is important!, if we are serving thousands of files per hour.

Ubuntu 32bits or 64bits?

Linux, Ubuntu

I’m setting up a new machine with 8cores and 8Gb of RAM.
I had to choose between Ubuntu 32bits or 64bits…

Ubuntu 64bits was the choice. Why?

If you have more than 4 GB of RAM go for 64 bit else 32 bit is just fine.

 

Use 64bit in case you do

  • video editing and processing
  • sound editing and processing
  • graphic editing and processing
  • work with large files (e.g. databases, large log files,…)

 

Got it from http://askubuntu.com/questions/19803/for-better-performance-should-i-install-32-bit-or-64-bit

Remove nginx – the ultimate guide

Linux, Ubuntu

I had some problems with nginx, ajenti and ajenti-v…

I’v removed nginx the easy way, with apt-get autoremove nginx etc, but when I tried to start the service after install it I was getting awk: cannot open /etc/nginx/nginx.conf and nginx didn’t started etc….

This is how I removed it!

sudo apt-get autoremove nginx
sudo apt-get --purge remove nginx
sudo apt-get autoremove -f && sudo apt-get autoclean -f
sudo find / | grep nginx | sudo xargs rm -rf

 

Ubuntu 12.04.3 LTS root password

Ubuntu

I need to access root under my Ubuntu 12.04.3 LTS, to accomplish some in-chain commands,  but I had no idea what is/was the password….

pjrfigueiredo@pornrack:~$ sudo wget http://repo.ajenti.org/debian/key -O- | apt-key add -
[sudo] password for pjrfigueiredo: ERROR: This command can only be used by root.

This is how I easily solved it…

sudo passwd

Voilá!

 

pjrfigueiredo@pornrack:~$ sudo passwd 
Enter new UNIX password: 
Retype new UNIX password: 
passwd: password updated successfully
pjrfigueiredo@pornrack:~$ su
Password: 
root@pornrack:/home/pjrfigueiredo# wget http://repo.ajenti.org/debian/key -O- | apt-key add -
