How to upgrade XAMPP?If an upgrade exists, you should use it: a) it's much smaller than the full XAMPP package and b) your configuration and HTML files won't be overwritten.Step 1: DownloadOkay, the first step is very obvious. Please download the upgrade packages from the XAMPP section of our website. Please take note that only matching upgrade packages can upgrade your XAMPP version.If you donwloaded a wrong version you will get an error message if you try to upgrade.Step 2: Extracting the archiveNow extract the downloaded package:tar xvfz xampp-linux-upgrade-x.x.x-y.y.y.tar.gzBy the way: It doesn't matter where in the filesystem you extract the packet. Just make sure it's on the same machine as your XAMPP installation. Step 3: Start upgradeAfter unpacking the archive you can start the upgrade process. First, get root access to your system, for example by using the 'su' command:suAnd now start the upgrade process: xampp-upgrade/startNow you should see something like this on your screen:
Ready. You successfuly upgraded XAMPP. By the way: the upgrade will stop a running XAMPP and will start XAMPP as soon as the upgrade is finished. XAMPP will be started after an upgrade even if it was not running before. Step 4: TestingNow use your favourite web browser and test the new XAMPP version by accessing your web site. For example simply type http://localhost in the location bar of your browser window. After upgrading you can delete the lampp-upgrade directory; it isn't needed any more.An error occurred during the upgrade! What now?Under special circumstances you can get the following warning message:
The upgrade program carefully tried to upgrade one of your configuration files. In order to upgrade the file, the program had to edit some lines you had already changed. Seeing as nobody wants to lose valuable configuration information, the upgrade program decided not to change the file but save a copy of the new file in addition to the original one. What's the meaning of the messages while starting XAMPP?You may get three error messages while 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. I got the error "/lib/libc.so.6: version `GLIBC_2.2' not found". What now?
What's the secret about "Error 1"?Good question :) This error can exist for multiple reasons. Apache spits out this error under several circumstances. To find the exact reason we have to do some research:tail -2 /opt/lampp/logs/error_logIf you now see "Invalid argument: Could not set permissions on ssl_mutex" or "Invalid argument: Unable to create scoreboard" please take a look at answers below. If you see another error message please email it to me. Maybe we can solve the problem together. My email address is oswald@apachefriends.org. Apache doesn't seems to start. What can I do?See "Error 1" above.What do I do if the error message is "Invalid argument: Could not set permissions on ssl_mutex"?The whole error message is:
In this case you have to change the Group directive (about line 318) in /opt/lampp/etc/httpd.conf. You should find there something like:
Change the "..." to "nobody", "nogroup" or #-1. One of these three possibilities should work. What do I do if the error message is "Invalid argument: Unable to create scoreboard"?The whole error message is:
In this case you have to remove the hash (#) in front of the Scoreboard directive (about line 71) in /opt/lampp/etc/httpd.conf. There, you should find something like:
Simply remove the hash at the beginning of this line:
Now this error message should not bother you anymore. What do I do if the error message is »Invalid argument: Configuration failed«?In this case, Apache is unable to get the IP address for your host name. It should normally work but sometimes (mostly if you're using DHCP) this situation could happen.Solution: Simply call the following command (Please use copy&paste. The ` characters are mandatory): echo 127.0.0.1 `hostname` >> /etc/hostsThis will fix the configuation error of your system and the »Configuration failed« error should dissapear. What do I do if the error message is »The configuration file now needs a secret passphrase (blowfish_secret)« shows up?This message may appear since XAMPP for Linux 1.2 was released. Since version 2.5.2, phpMyAdmin supports the encryption of cookie-saved passwords.Solution: Edit config.inc.php at line 60. You find this file in the phpmyadmin directory of your XAMPP installation. The line should look like this:
Enter in this line a password-like word or phrase, for example:
That's all. You should now be able to use phpMyAdmin in the same way as before. What do I do if the error message is »cannot restore segment prot after reloc: Permission denied«?I assume you are using Fedora? Since version 4 - I think - SELinux is activated by default and this is preventing the succesful start of XAMPP.Solution:At the moment I only know one solution - deactivating SELinux:
Now XAMPP works fine again. If you know a better solution, please email me. I'm no SELinux expert and the only I know about SELinux is how to disable it. ;) After I rebooted my Linux box XAMPP stopped running! How can I fix this?Correct. That's normal Linux behaviour (which applies to any other Unix-like system. It's the admin's job to make sure a particular application is started at bootup.There is no real standard way to configure the boot process of a Linux system, but most of them should allow you to start XAMPP at boot time using the following steps.
OpenSuSE 10.0 is a little bit stange: You need to set up a symbolic link from /etc/init.d/lampp to /opt/lampp/lampp: ln -s /opt/lampp/lampp /etc/init.d/lampp And than use the runlevel editor (expert mode) from YaST to activate XAMPP for the specific runlevels. How can I make my XAMPP installation more secure?In the default installation, XAMPP has no passwords set and it is not recommended to run XAMPP with this configuration accessible by others (e. g. on the Internet).Simply type the following command (as root) to start a simple security check:/opt/lampp/lampp securityNow you should see the following dialog on your screen (user input is highlighted): XAMPP: Quick security check... XAMPP: Your XAMPP pages are NOT secured by a password. XAMPP: Do you want to set a password? [yes] yes (1) XAMPP: Password: ****** XAMPP: Password (again): ****** XAMPP: Password protection active. Please use 'lampp' as user name! XAMPP: MySQL is accessable via network. XAMPP: Normaly that's not recommended. Do you want me to turn it off? [yes] yes XAMPP: Turned off. XAMPP: Stopping MySQL... XAMPP: Starting MySQL... XAMPP: The MySQL/phpMyAdmin user pma has no password set!!! XAMPP: Do you want to set a password? [yes] yes XAMPP: Password: ****** XAMPP: Password (again): ****** XAMPP: Setting new MySQL pma password. XAMPP: Setting phpMyAdmin's pma password to the new one. XAMPP: MySQL has no root passwort set!!! XAMPP: Do you want to set a password? [yes] yes XAMPP: Write the passworde somewhere down to make sure you won't forget it!!! XAMPP: Password: ****** XAMPP: Password (again): ****** XAMPP: Setting new MySQL root password. XAMPP: Setting phpMyAdmin's root password to the new one. XAMPP: The FTP password for user 'nobody' is still set to 'lampp'. XAMPP: Do you want to change the password? [yes] yes XAMPP: Password: ****** XAMPP: Password (again): ****** XAMPP: Reload ProFTPD... XAMPP: Done. (1)Setting a password will protect the XAMPP demo pages (http://localhost/xampp/) using this password. The user name is 'lampp'! After calling this command your XAMPP installation should be "secure". For my part I've no idea what else could be insecure. How do I activate eAccelerator?(since XAMPP for Linux 1.4.12)To activate eAccelerator simply find the following lines in your /opt/lampp/etc/php.ini:
Remove the semicolon at the beginning of each line and restart XAMPP. eAccelerator is now active. For more information about eAccelerator, check the eAccelerator home page:  http://eaccelerator.net.How do I activate the OCI8/Oracle extension for PHP?(since XAMPP for Linux 1.3)To activate the OCI8/Oracle extension for PHP please execute the following command:/opt/lampp/lampp oci8The following dialog will start:
Now the extension should be active. I have only had a few chances to test this feature, so please report if this worked for you or not: oswald@apachefriends.org. XAMPP currently only supports Oracle 10 out of the box. If you're using Oracle 11 you may need to put your own hands on. Also XAMPP is a 32 bit only application which only works with a 32 bit Oracle client library. Both limitations only affect the Oracle client library XAMPP is linking to. On the server's side you may use any Oracle version you like. XAMPP runs, but none of the images are shown?That's a special problem with some Linux systems. Please open your /opt/lampp/etc/httpd.conf and look for these two lines:#EnableMMAP offRemove the # in both lines and restart your Apache. Now you got all your images back. How do I backup/restore my XAMPP system?Since XAMPP for Linux 1.4.2 you can make easily backups of your XAMPP data. |
| Warning: The backup and restore functionality is still under development and may not work correctly. Attention: There is a small but annoying bug in version 1.4.2 of XAMPP. Please take a look here! |
Step 1: Creating the backupCreate the backup by calling:/opt/lampp/lampp backup or /opt/lampp/lampp backup secret Where secret is your MySQL root password. This command will create the following output:
Step 2: Take care of your backuped dataThe file /opt/lampp/backup/xampp-backup-22-01-04.sh (in the example above) contains your backuped data. Get this file to a save place.Step 3: Restore your backuped dataOn the new machine you need the same version of XAMPP as on your original/source machine.Call (as root):sh xampp-backup-22-01-04.sh You shoud see something like this:
That's all. As you can read you may need to restart XAMPP. It should work perfectly (I tested it many times) but remember it's a beta feature. |
