(Python) Mysqldump Backup 1.1

Andreas Glaser — Mon, 12 Apr 2010 08:00:02 +0000

Backups are crucial!
Since that is fact I wrote a little script in Python to easily backup mysql databases on a linux server.

Note: There is a file embedded within this post, please visit this post to download the file.

How do i configure it?
After you downloaded the script to your Linux server you will need a few Linux packages. Execute the following commands as root:

apt-get update
apt-get install python mysqldump bzip2

What does it do?
This script dumps a certain database (or all databases) into a single mysql file, which is zipped (bzip2) afterwards.

Now edit the script with your preferred editor.

vim mysqldump-backup.py

Customize the following lines:

# 2. Config
mysqlUser = “root”
mysqlPwd = “YOUR_PASSWORD”
mysqlDatabase = “–all-databases”
dumpDir = “/tmp/”
dumpFile = “mysqldump-” + strftime(“%Y-%m-%d-%H-%M-%S”, gmtime()) + “.sql”

The last step is to make the script executable:

chmod u +x mysqldump-backup-1.1.py

Thats it!

You can now run the script:

/path/to/the/script/mysqldump-backup-1.1.py

To run it daily (crontab):

crontab -e

Add at the bottom:

0 3 * * * /path/to/the/script/mysqldump-backup.py

Now your databases will be backupped daily at 03:00 am

PHP – SRCDS/HTTP Synchronizer (Linux)

Andreas Glaser — Thu, 03 Dec 2009 17:03:04 +0000

I just came across a script I have totally forgotten about, which I wrote quite a while ago.
I haven’t managed to write a real documentation so far… anyway… feel free to try it.

All you need to do, is to install php in case you haven’t done it already!

CounterStrike Source Linux Server Startscript

Andreas Glaser — Fri, 05 Sep 2008 17:01:10 +0000

Here it is… a well commented and easy for rookies to understand CounterStrike Source Linux Server Startscript. It includes all basic start parameter as well as a good error display system.

How to use:

After you successfully installed a Counterstrike Source Server under Linux with the SRCDS tool you just have to download the startscript at the bottom of this post.
Save the “startscript” into the root directory of your CSS server and change the permission to “u + x” (chmod u+x startscript).

Now open the start script with your preferred editor (vim, joe, mono etc.) and customize the configuration variables to your system.

PHP – count() vs. sizeOf()

Andreas Glaser — Tue, 19 Aug 2008 08:51:57 +0000

I was wondering whether there is a performance difference between count() and sizeof().

Test code:

^?View Code PHP

&lt;?PHP
 
  // CREATE TEST ARRAY
  $a = array('a','b','c','d','e','f','g','h','i','j');
 
  // START TIMER ONE
  $TimerOne = benchmarkTimerStart();
 
  // CALL COUNT FUNCTION 1000000 TIMES
  for($i=0;$i&lt;1000000;$i++)
  {
    count($a);
  }
 
  // STOP TIMER ONE
  $ResultOne = benchmarkTimerStop($TimerOne);
 
  // START TIMER TWO
  $TimerTwo = benchmarkTimerStart();
 
  // CALL SIZEOF FUNCTION 1000000 TIMES
  for($i=0;$i&lt;1000000;$i++)
  {
    sizeOf($a);
  }
 
  // STOP TIMER TWO
  $ResultTwo = benchmarkTimerStop($TimerTwo);
 
  // PRINT RESULTS
  echo 'Count: '.$ResultOne.' Seconds<br />';
  echo 'SizeOf: '.$ResultTwo.' Seconds';
 
  // TIMER FUNCTIONS
  function benchmarkTimerStart()
  {
    $timeExplode = explode(" ", microtime());
    $time = $timeExplode[1] + $timeExplode[0];
    return $time;
  }
 
  function benchmarkTimerStop($timer=0)
  {
    $timeExplode = explode(" ", microtime());
    $time = $timeExplode[1] + $timeExplode[0];
    $finish = $time - $timer;
    $endTime = sprintf("%4.3f", $finish);
    return $endTime;
  }
?&gt;

My test proved that there is no difference at all! sizeof() is just an alias for count().
So I suggest you to use count() – its the original name of this function.

So long,
Andreas Glaser (aka JaZz)
