I can’t get MySQL to work!!! Something about mysql.sock…


So you’ve got problems getting MySQL to start? You’re not alone. There are a couple of things you can do to get things rolling. Linux comes with a database that tells it how to add MySQL users and MySQL tables. However, MySQL is not started by default…and if it is, it requires that default table to be created before it can run without incident. Here are the commands you can issue to get things going:

cd /usr/bin
su mysql
mysql_install_db

Lastly, issue the command:

mysqld_safe &

What you’ve just done is logged into you Linux box as user mysql, then installed the default database…and then with the mysqld_safe & command you initiated the mysql daemon to run in the background. So, things should be good to go now. MySQL is running and you’ll be able to press on with things by adding users and databases.

A bit more info for you…creating databases and users can get tedious via the linux prompt. You can use phpmyadmin or webmin to automate this process and save yourself time and effort.

Slackware 10.2 Tips and Tricks

Want to Install the 2.6.13 Kernel is Slack but don’t know how? Ask and ye shall receive!

First, mount the CDROM…in my case, it is /dev/hdb

mount -t auto /dev/hdb /mnt/cdrom

or

mount -t auto /dev/cdrom /mnt/cdrom

Next, let’s install that Kernel! Insert Slackware Disc 2…then issue the commands below.

installpkg /mnt/cdrom/linux-2.6.13/kernel-source-2.6.13-noarch-1.tgz

 

installpkg /mnt/cdrom/linux-2.6.13/kernel-modules-2.6.13-i486-1.tgz

 

installpkg /mnt/cdrom/linux-2.6.13/kernel-headers-2.6.13-i386-1.tgz

 

installpkg /mnt/cdrom/linux-2.6.13/kernel-generic-2.6.13-i486-1.tgz

 

installpkg /mnt/cdrom/linux-2.6.13/alsa-driver-1.0.9b_2.6.13-i486.1.tgz

KDE Shortcut Keys

Most people know shortcuts in Windows but neglect to find out shortcuts in KDE when they make the switch to Linux. So, if you have a shortcut in KDE that isn’t covered here…please comment it so that others can benefit from your knowledge! PS: Some of these might not work with your version of KDE…just test them out and see if they do!

Alt-F2
Brings up a “Run Command” prompt

Alt-Print and Cntrl-Print
Take a screenshot. You have to paste it from your clipboard

Alt-Esc or Control-Esc
Shows the KDE session manager, from which you can switch to a specific application or log out of KDE.

Ctrl-F[1..8]
Switch to a specific desktop.

Alt-Tab or Alt-Shift-Tab
Cycle through your windows.

Ctrl-Tab or Ctrl-Shift-Tab
Cycle through your desktops.

Alt-F4
Close the current active window.

Ctrl-Alt-Esc

Ctrl-Alt-Backspace
This exits KDE but doesn’t save your settings or work.

Ctrl-Alt-Numpad +
Cycles to the next screen resolution available.

Ctrl-Alt-Numpad –

Hope these help you out…please post any you might have that are helpful and I’ll add them to the list with credits. Thanks again for reading.

The 10 Minute Linux Firewall

If you’re like me…you still have to run some form of Windows for daily operations at your house or office. While most of the time there are helpful hardware additions at work such as a firewall/avtivirus…at home, you’ll find a more simple router/firewall and antivirus solution that doesn’t protect as well. While this is better than nothing, it also doesn’t have the power that a Linux firewall does…nor does it have the ability to patch itself when a vulnerability is discovered.

Did you know that most router/firewalls that you can buy at the store come with a set of default passwords that work on ALL MODELS? Yours could be open to hacking right now. To lock down your network, you can take an old computer, install Linux, and use it as a firewall with your own custom rules and regulations…plus it’s great to show off to the ladies Wink 😉 lol.

I wrote a tutorial on how to do this at http://daniweb.com. If this sounds like something you’d be interested in (very easy to follow directions) then check out this link: http://daniweb.com/tutorials/tutorial14094.html.

The 10 Minute Linux Firewall

At the forefront of almost every single System Administrators mind is security. Redmond has been catching a lot of flack lately about not being as secure as they could be. As some of you have noticed, there has been a market swing in the use of Mozilla and Firefox as webbrowsers, creating a small nick into the 90% marketshare that Redmond owns with IE. Some IT Specialists are also seeing the same swing in the Server market.

So what does this have to do with Firewalls? Well, just like switching webrowsers or servers away from M$, a Linux firewall means added security AND possibly even increased browsing speed. Today, I’ll discuss the easiest way to get up and running with the 5 minute Linux firewall.

First things first. I’m not going to go into detail on many distros…I’m going with one that I know work…and that I know work FAST…and that would be something a ‘Windows’ person could install and configure in a matter of minutes. In my mind, the easiest distro is Smoothwall.

More 350 MHz Mayhem

Based on some recommendations from those commenting to my previous entry…I will attempt a few more distros on my old PII 350 MHz PC…using the XFCE Desktop of course. I’ll attempt to get the latest and greatest XFCE up and running.

Those that I’ve received feedback on are:

 

 

  1. STX Linux
  2. DSL – Damn Small Linux
  3. Puppy Linux
  4. Kanotix
  5. Zenwalk
  6. Debian Unstable (for XFCE cutting edge)
  7. Wolvix
  8. PCLinuxOS – Second attempt after remaster (because it is my favorite 🙂 )

So, I’ll give those a go during the next week or two and we’ll see how they stack up. I’m looking forward to STX since it is slackware based and has many features (thanks for pointing it out srlinuxx!!). Check it out in a review at Tuxmachines.org.

I’m also looking forward to Kanotix because I’ve heard good things about this distro. We’ll see where everything stacks up in a few weeks. Stay tuned. And if anyone has any more suggestions for distros to try, let me know…I’m all for trying out even more…I normally am testing something out and testing Linux on a PII 350 is challenging and fun.

Keep in mind that I’ll be attempting to get XFCE (my choice of minimalistic desktop…if I can’t have XFCE, the distro isn’t worth it for me) on each distro. If anyone would like to assist me with the distros listed above with pointers for XFCE, drop a line in the forum on this thread. Thanks for your help!

The 350 Mhz XFCE Linux Desktop Search

I’ve had troubles as of late in my household. I had a motherboard go bad that was powering my Media Center PC. This PC is the center of the entire family entertainment with 30 GB of music, 50 GB of movies, and the ability to watch live TV. That immediately ceased when the BIOS chip failed on the mobo. I had to send in for a replacement. In the meantime, I’ve had to shift all of my computers around to compromise for this loss. This means that I lost my normal Linux (PCLinuxOS .92) computer (an old Celeron 900 Emachines). I now have the old PII 350 MHz. While I know it likes Slackware and Vector Linux the most…I have to try other distros out on it just to see what happens. After all, even Windows XP can install and run on this computer…so I’d like to see how some of the better Linux desktops will run on it. To give a quick rundown, here are the specs:

  • ATI Rage Pro Video Card
  • 512MB PC133 Crucial
  • PII MMX 350 MHz
  • Samsung 32X CDROM
  • Western Digital 20 GB 5400 RPM Hard Drive
  • Linksys 10/100 Network Card
  • Sound Blaster 16

Even if my hand is forced in this round with the inclusion of such an old desktop system, I don’t mind. Let’s see how some of the big distros work using this PII 350 MHz shall we? I’m going to attempt to get a good desktop based distro running with an XFCE desktop. If a distro ships with Gnome, I can handle that as well…KDE won’t do though since it will run very slow on this PC.

PCLinuxOS

Unfortunately, this didn’t want to boot. It got stuck on searching for the loop image during bootup. I tried pumping down resolutions and not probing practically anything but it just wouldn’t boot. Every single boot option in my arsenal came up nil. I didn’t think this would work for me, but I just figured I’d give it a try. I know PCLinuxOS is cutting edge normally with the best Intel and AMD processors…but I just figured that I might be able to run it with XFCE powering the desktop. So, it seems that PCLOS is good for newer computers but not what the doctor ordered for older computers. Darn, I really wanted this one to work. Next up, SuSe 10.0…
