Virtualmin, apache2 group/user problem

I moved virtualmin installation from one system disk to another but left in use old hard disk mounted on /home. After setting up virtualmin backup, user/group permissions was incorrect for almost all domains, for example, domain had group/user I chowned all files manually and websites worked fine until I enabled/disabled some apache2 modules.

When I make/edit files with php scripts, these files made by php have user/group www-data not and I can not edit them later. I can only if I add chmod(“777”); in this script which is editing files. How can I make that files edited by PHP don’t have www-data user/group but user’s real group? Thank You!<br><br>Post edited by: malinens, at: 2009/04/11 01:02

And I have some strange things with apt-get (Ubuntu):

[code:1]The following packages were automatically installed and are no longer required:

Some of these packages I think is important…

I moved virtualmin installation from one system disk to another but left in use old hard disk mounted on /home.

Are you sure that’s all you did? The UID/GID wouldn’t change just because you copied some files (assuming you used the right flags to preserve ownership and permissions).

After setting up virtualmin backup, user/group permissions was incorrect for almost all domains, for example, domain had group/user

Ah…so, you didn’t just move disks. You’ve gone to a different OS installation and didn’t do a normal backup/restore in Virtualmin. You’ve just got the /home directory sitting around, while the new system has a bunch of new UID/GIDs. That’s not really the way I’d recommend moving things around. Just copying to a new disk would work fine. Or, doing a Virtualmin backup from the old running system and then restore on the new running system, that would also work fine. But, trying to do a half-backup half-old disk kind of thing is just asking for trouble.

The following packages were automatically installed and are no longer required

I suspect you uninstalled virtualmin-base somewhere along the way. Uninstalling virtualmin-base is mostly harmless.

Uninstalling these packages, on the other hand, would cause massive breakage. Your server would pretty much stop working altogether. No web, no mail, many Virtualmin modules and the theme gone, no web stats, no POP/IMAP service, no FTP, and more. Yep, that’d be a real bad day. You’d have no choice but to start over and restore from backups.

My sistem worked fine for a while after I manually wrote chown -R aa:aa aa, chown -R bb:bb bb. But once I enabled/disabled some apache2/php modules and now I php scripts make files with www-data user/group and it is NOT because I had problems with migrating to another system disk. This is the only bug I have seen (email, DNS works perfectly).

I enabled/disabled some apache2/php modules and now I php scripts make files with www-data user/group

If you want it to run as the user, you need to switch to one of the suexec modes of execution for PHP scripts (instead of mod_php). mod_fcgid or CGI. You can find this in Server Configuration->Website Options for the virtual server you want to change.

Hi Joe!

Server Configuration->Website Options - I don’t have Website options but I have Configure Website under the “Services” menu. I can’t find where I can change from mod_php to fcgid.

Hrm, “Website Options” doesn’t appear to be available in the GPL version of Virtualmin.

I’m not sure whether that’s an oversight, or whether there’s a different way to do all that on the GPL version. I’ll ask Joe/Jamie to chime in :slight_smile:

the gpl version doesn’t have this.
It is a Pro feature.
You can however do it manually and that is described in this forum a few times.

you can change www-data to apache though if you prefer this.
"If you wish httpd to run as a different user or group, you must run
httpd as root initially and it will switch."

ronald’s right.

The PHP execution mode handling code is part of the Install Scripts feature. This is sort of historical, and will probably eventually be changed to become part of the core (and thus in Virtualmin GPL).

But, right now, you have to tweak a few things to run things under mod_fcgid. I have documented this several times on the forum…it’s not very difficult. I’m pretty sure I’ve even stickied one of the threads about it.

I just assumed because of the way you phrased it "I enabled/disabled some apache2/php modules and now I php scripts make files with www-data user/group", that you had previously seen different behavior…which made me think you were running Pro. But, GPL would have never offered other behavior.
