see: http://www.aboutlinux.info/2006/04/enabling-and-disabling-services-during_01.html

sudo /opt/lampp/lampp start

How do I stop XAMPP?
To stop XAMPP simply call this command:

sudo /opt/lampp/lampp stop

How can I test that everything worked?
Type in the following URL at your favourite web browser:
http://localhost/xampp/index.php

开了 goagent，一直打不开，怪不得...

Is XAMPP production ready?

sudo /opt/lampp/lampp security

What is the meaning of the error messages I see when starting XAMPP?

LAMPP-Apache is already running.
An Apache daemon is already running.

The LAMPP startup script did not start XAMPP-Apache because there is an Apache instance already running. To start XAMPP properly, first you have to stop this daemon.

LAMPP-MySQL is already running.
A MySQL daemon is already running.

Mostly due to the same reasons as the above error, the LAMPP startup script found a MySQL daemon already running on your system. To start LAMPP properly, you have to stop this daemon first.

Apache doesn‘t seems to start. What can I do?

tail -2 /opt/lampp/logs/error_log

If you get any error messages visit our community pages for help.

*What do I do if the error message is "Cannot restore segment prot after reloc: Permission denied?"*

sudo /usr/sbin/setenforce 0

After I rebooted my Linux box XAMPP stopped running! How can I fix this?
Debian, Ubuntu.

sudo ln -s /opt/lampp/lampp /etc/init.d/lampp
sudo update-rc.d lampp start 80 2 3 4 5 . stop 30 0 1 6 .

RedHat, Fedora, CentOS. If your Linux distro uses "chkconfig" tool to install the services you can run the following commands:

sudo ln -s /opt/lampp/lampp /etc/init.d/lampp
sudo chkconfig --add lampp

SUSE

sudo ln -s /opt/lampp/lampp /etc/init.d/lampp
sudo chkconfig lampp 2345

How can I make my XAMPP installation more secure?

How do I activate eAccelerator?
To activate eAccelerator simply find the following lines in your /opt/lampp/etc/php.ini:

;extension="eaccelerator.so"
;eaccelerator.shm_size="16"
;eaccelerator.cache_dir="/opt/lampp/tmp/eaccelerator"
;eaccelerator.enable="1"
;eaccelerator.optimizer="1"
;eaccelerator.check_mtime="1"
;eaccelerator.debug="0"
;eaccelerator.filter=""
;eaccelerator.shm_max="0"
;eaccelerator.shm_ttl="0"
;eaccelerator.shm_prune_period="0"

How do I activate the OCI8/Oracle extension for PHP?
To activate the OCI8/Oracle extension for PHP please execute the following command:

sudo /opt/lampp/lampp oci8

The following dialog will start:

Please enter the path to your Oracle or Instant Client installation:
[/opt/lampp/lib/instantclient-11.2.0.3.0]

Now the extension should be active.

XAMPP runs, but why are none of the images being displayed?
That‘s a special problem with some Linux systems. Please open your /opt/lampp/etc/httpd.conf and look for these two lines:

#EnableMMAP off
#EnableSendfile off

Remove the # in both lines and restart your Apache. Your images should be back.

How do I backup/restore my XAMPP system?
Warning: The backup and restore functionality is still under development and may not work correctly.
You can create the backup by calling:

sudo /opt/lampp/lampp backup

or

sudo /opt/lampp/lampp backup secret

Where "secret" is your MySQL root password. This command will create the following output:

Backing up databases...
Backing up configuration, log and htdocs files...
Calculating checksums...
Building final backup file...
Backup finished.
Take care of /opt/lampp/backup/xampp-backup-22-01-14.sh

The file /opt/lampp/backup/xampp-backup-22-01-14.sh (in the example above) contains your backup data. Store this file in a safe place.
On the new machine you need the same version of XAMPP as on your original/source machine.

sudo sh xampp-backup-22-01-14.sh

You should see something like this:

Checking integrity of files...
Restoring configuration, log and htdocs files...
Checking versions...
Installed: XAMPP 1.4.2
Backup from: XAMPP 1.4.2
Restoring MySQL databases...
Restoring MySQL user databases...
Backup complete. Have fun!
You may need to restart XAMPP to complete the restore.
