PECL Memcache client of memcached distributed cache server, is a very probable candidate for high-load systems.
Typically you won’t be able to use “pecl” directly and when you try to install manually with phpize you will get an error like:
” PHP Warning: Unknown(): Unable to load dynamic library ‘/opt/lampp/lib/php/extensions/no-debug-non-zts-20020429/memcache.so’ – /opt/lampp/lib/php/extensions/no-debug-non-zts-20020429/memcache.so: undefined symbol: OnUpdateLong in Unknown on line 0″
Below is step-by-step guide of how to install a PECL extension (Memcache in this case) in the latest XAMPP:
make sure you uninstall all and any PHP installations you may have had before along with PECL and PEAR
Download and install XAMPP 1.7.1
Add /opt/lampp/bin to your PATH
Download and install XAMPP Development Package
backup /opt/lampp/include directory to /opt/lampp/include-bak. This directory
Download source distribution of the PHP corresponding to your XAMPP installation
SWFTools is the utilities for working with Adobe Flash files. These tools includes programs for reading SWF files, combining them, and creating them from other content (like images, sound files, videos or sourcecode).
Download latest Sourcecode from here…
# wget http://swftools.org/swftools-0.9.0.tar.gz
# tar -zxvf swftools-0.9.0.tar.gz
# cd swftools-0.9.0
Some time make generate errors for xpdf.. so we have to install xpdf here….
Search for “xpdf-3.02.tar.gz” download & install
# cd lib/pdf
# wget http://gd.tuwien.ac.at/publishing/xpdf/xpdf-3.02.tar.gz
# perl inject-xpdf.pl xpdf-3.02.tar.gz
# make clean
# make install
Here we successfully installed swftools for all swf related operations.
We can find all linux utilities in src for of “swftools-0.9.0” like
Make the store’s appearance and organization..
* Add products
* Categorize products
* Create a navigation menu
* Configure payment options
* Configure shipping options
* Configure taxes
* Customize the front page
* Process orders
Now you should be having xampp-linux-1.7.3a.tar.gz in your downloaded location
Go to a Linux shell and login as root:
Perform these commands as root user
$ su -p
Extract the downloaded archive file to /opt
#tar xvfz xampp-linux-1.7.3a.tar.gz -C /opt
XAMPP is now installed below the /opt/lampp directory.
Start XAMPP Server
To start XAMPP simply call this command:
Starting XAMPP for 1.7.3a…
XAMPP: Starting Apache with SSL (and PHP5)…
XAMPP: Starting MySQL…
XAMPP: Starting ProFTPD…
XAMPP for Linux started.
Test Your XAMPP Installation
OK, that was easy but how can you check that everything really works? Just type in the following URL at your favourite web browser:
XAMPP Security Configuration
As mentioned before, XAMPP is not meant for production use but only for developers in a development environment. The way XAMPP is configured is to be open as possible and allowing the developer anything he/she wants. For development environments this is great but in a production environment it could be fatal.
Here a list of missing security in XAMPP:
The MySQL administrator (root) has no password.
The MySQL daemon is accessible via network.
ProFTPD uses the password “lampp” for user “nobody”.
PhpMyAdmin is accessible via network.
Examples are accessible via network.
MySQL and Apache running under the same user (nobody).
To fix most of the security weaknesses simply call the following command:
It starts a small security check and makes your XAMPP installation more secure.
Start And Stop Server Services
Stops and starts XAMPP.
Starts only the Apache.
Starts the Apache SSL support. This command activates the SSL support permanently, e.g. if you restarts XAMPP in the future SSL will stay activated.
Starts only the MySQL database.
Starts the ProFTPD server. Via FTP you can upload files for your web server (user “nobody”, password “lampp”). This command activates the ProFTPD permanently, e.g. if you restarts XAMPP in the future FTP will stay activated.
Stops the Apache.
Stops the Apache SSL support. This command deactivates the SSL support permanently, e.g. if you restarts XAMPP in the future SSL will stay deactivated.
Stops the MySQL database.
Stops the ProFTPD server. This command deactivates the ProFTPD permanently, e.g. if you restarts XAMPP in the future FTP will stay deactivated.
Starts a small security check programm.
For example: To start Apache with SSL support simply type in the following command (as root):
You can also access your Apache server via SSL under https://localhost.
Important Configuration Files And Directories
/opt/lampp/bin/ – The XAMPP commands home. /opt/lampp/bin/mysql calls for example the MySQL monitor.
/opt/lampp/htdocs/ – The Apache DocumentRoot directory.
/opt/lampp/etc/httpd.conf – The Apache configuration file.
/opt/lampp/etc/my.cnf – The MySQL configuration file.
/opt/lampp/etc/php.ini – The PHP configuration file.
/opt/lampp/etc/proftpd.conf – The ProFTPD configuration file. (since 0.9.5)
/opt/lampp/phpmyadmin/config.inc.php – The phpMyAdmin configuration file.
1. dump the content of the existing crontab to a file # crontab > /tmp/dump
2. echo “your lines” >> to the corntab file # echo ” 00 1 * * * /monitor_file_system 2>/dev/null” >> /tmp/dump
3. import the new crontab # crontab /tmp/dump
other option…. # crontab -e
It will open a editor, add job here like
00 1 * * * /monitor_file_system 2>/dev/null
Set cronjob from other server:
# crontab -e
0 0 * * * curl http://www.domain.com/svnlabs.php
here svnlabs.php file is located on different server…
and save this crontab files…. now cronjob successfully installed 🙂
