[opensuse-support] [Leap 15] Apache server on localhost - file ownership?

I want to make a copy of my Joomla website to run on my local machine here, so that I can experiment with new modules and settings in a safe environment before committing them to the active site. I have set up a LAMP server - It works! I have copied all the files from the remote server to /srv/www/htdocs/mydomain using wget. I have exported the mysql database with phpMyAdmin and imported it into the local mysql(mariadb) database server. I have edited the configuration files to suit the new environment (I don't rule out some errors here) When I try to visit http://localhost/mydomain in Firefox, I just get a white page (Object not found). Initially, I had root:root owning all the files, but when that didn't work I tried changing it to wwwrun:wwwrun. But that didn't help either. ISTR reading that in this situation, the Apache webserver should own the files, but I don't know what (s)he's called on Leap 15. Any suggestions? I've already googled and searched the Joomla forums. Many thanks Bob -- Bob Williams System: Linux 4.12.14-lp150.12.58-default Desktop: KDE Frameworks: 5.45.0, Qt: 5.9.4 and Plasma: 5.12.5

You need wwwrun:www on openSUSE.

I think I used the YaST software management pattern, but that bit was done a while ago and I didn't flag it as something to remember :( I've changed the file ownership to wwwrun:www but it's made no difference.

Not really ;-) Apache runs as user wwwrun, and needs to be able to _read_ files as this user. As long as wwwrun can read the files, Apache doesn't care about the owner. The only exception are files that need to be _written_ by Apache or PHP. These files or directories really have to be owned by wwwrun (or group www + group write permissions). For everything else, using another user as file and directory owner is more secure because that means Apache or PHP can't modify the files. This is an important feature if your joomla/wordpress/... ever gets hacked ;-) Regards, Christian Boltz --

Christian, I stand corrected. If it's your development version it's better to run it as your own user, so you can edit your files. I forgot about this since I've found other means to develop, test and push. Where indeed I don't use the default webuser. -- Gertjan Lettink a.k.a.

That's a clear indication that you miss a file - probably '/srv/www/htdocs/brightonbelle.org/libraries/vendor/joomla/string/src/ phputf8/mbstring/core.php' It could also be that your server has .../mbstring/core.php in its include_path (and the include_path could be different than what you have on your local machine). However, I'd _guess_ that this is unlikely because the path looks very joomla-specific. Please double-check if the requested file exists on the server (the base path probably differs). A quick search shows that both mentioned files are probably included in joomla: https://github.com/joomla/joomla-cms/tree/staging/libraries/vendor/ joomla/string/src/phputf8 Another wild guess is that these files might or might not be used based on the PHP extensions you have loaded. I don't know the joomla code, but maybe they are only used as a fallback if you don't have the mbstring extension installed. Comparing the output of <?php phpinfo() ?> might help to find out, or simply try zypper in php7-mbstring && rcapache2 restart on your local machine.

php7-mbstring is installed on my local machine, so I copied the missing files to the Joomla installation. As well as core.php, it also wanted ascii.php. This improved things to the extent that the white page now contains the single word 'Error'.

I can recommend to google for the error message - the search results include hints for - PHP version vs. joomla version - older joomla won't work with latest PHP, try updating to the latest version - session save path might be wrong, not writeable by PHP etc. - https://forum.joomla.de/thread/5193-nach-template-upload-nichts-geht-mehr/ might also be a reason (in german, use google translate to get the english version) In general, this looks like a joomla-specific problem, so you might have more luck in a joomla forum or mailinglist.

I've hunted down all the missing files, and made some corrections in configuration.php and the site now loads, but not completely. My browser complains about the certificate. The remote host provides its own certificate, but as this is just a local installation (not publicly available) I don't need to bother with certificates. Or I need to provide my own, but that's another, different learning curve for me. So, nearly there but not quite.
