Maximum user id for this system is reached! And multiple subdomain problems. - prale - 11-11-2008 11:42 PM

Hello.

Lets start from the beginning.

I had the users:
sub1.domain1.com
sub2.domain1.com
sub1.domain2.com
sub2.domain2.com (with redirect alias from domain1.com)

(I don't use multiple subdomains on accounts because I like the openbasedir rule that every seperate user has)

I deleted the user sub2.domain2.com since I couldn't remove the alias (the error keeps saying there are still emailaccounts (indeed there was 1 forward from this alias), but even after I deleted it, still the same error).

Then I created a new user domain1.com.
After this, domain1.com was working great but I found out that the earlier subdomain users of this domain1.com (sub1.domain1.com and sub2.domain1.com) were not working any more, It shows the content of the user domain1.com.

I have other domains where this setup is working correct.
But there I first created a domain.com user and then the subdomain users.
(So maybe it went wrong because I added the maindomain after the subdomains were already created)

Anyway I tried some regeneration of the config files.
I tried to disable the subdomains, regenerate config and then activate the subdomains again (since then the maindomain was still there).
Also I tried to disable all users and enable the maindomains first and then the subdomains.
No luck. :S
Even a few sites went down, because they were already reactivated in the UI but the htdocs and all other maps/files were still in a subfolder with a prefix: .disabled
I had to copy them one folder back manualy from ssh.
(Probably I expect some chmod problems here, since I remember there was some trouble with it)

Now domain1.com still works but sub1.domain1.com and sub2.domain1.com not.

I upgraded today to the latest nightly.
Regenerated config, updated database etc, still no luck.

I tried even adding a new user:
test.domain1.com
but this user cannot be added

Here is some error info:
check_uid_gid_available() | ERROR: Maximum user id for this system is reached!

get_file() | ERROR: File '/etc/ispcp/proftpd/parts/proftpd.conf.tpl' does not exist !

(see attachment)
I fixed the userid problem:

/etc/ispcp/ispcp.conf was incomplete somehow after the upgrade from nightly to nightly:

This was present:
APACHE_SUEXEC_MIN_GID = 2000
APACHE_SUEXEC_MIN_UID = 2000

This not:
APACHE_SUEXEC_MAX_GID = 29999
APACHE_SUEXEC_MAX_UID = 29999

So the expression:
if($sys_uid > $max_uid){
push_el(\@main::el, 'check_uid_gid_available()', "ERROR: Maximum user id for this system is reached!");
return (2, $sys_uid, $sys_gid);
}

Would always be true, since $max_uid is not defined.
Somehow when I check test.domain1.com it gives me a error 404.
(At least not the content from domain1.com Smile like sub(1,2).domain1.com still do)
When I check the files of this user, there isn't even a htdocs folder.
(Only backups, errors, and phptmp)

In my next commit I`ll add a patch to check ispcp.conf for missing variable. Problem is that for nightly updates ispcp.conf is not regenerated.

Okay,

after I deleted the users:
sub1.domain1.com
sub2.domain1.com

and recreated them, both virtual folders were empty.

I created the errors, htdocs, cgi-bin, logs, and phptmp folders manually.
I had to chmod htdocs tot 777 :S otherwise I cant upload content in it with ftp.
Also phptmp needed to be chmodded or I get session errors.

Anyway I have the subdomains working again, and also the maindomain still shows the right content.

The folders parts and working were missing from /etc/ispcp/proftpd/
I had to create them manualy (as wel als /parts/proftpd.conf.tpl wich I took from SVN), and now the errors on the debug page are gone, as wel as the execute requests.

Still I think alot is messed up now, I guess more files are missing, and the chmods I had to do were probally not right to do.

What can I do?
I'm thinking of reupgrading to the latest nightly tomorrow.
And find a way out to regenerate/check al chmods and folders in /var/www/virtual/ without doing damage to the sites currently running.

Another way is to backup everything and do a new install, but I have a complicated config and also some trac environments on some domains, so I would like to keep thing the way they are.

What can I do?
Okay I used your super-lazy automated update script this time.
Thanx sci2tech Wink

It runned fine, so I guess I have the lastest SVN files now also in /etc

The only problem left now is the missing folders and chmods in some parts of /var/www/virtual

I have to regenerate/check them somehow

Please check if user is added to /etc/shadow and /etc/groups

It`s not messed up, but we do not have a script to update to nightly versions that work perfectly. Existing one do not update configuration files. A good way to do an upgrade to nightly is to keep your curent installed trunk from svn and do a compare to new version from svn (mostly changes to configuretion files) and manually merge it.
I`ll start working on a better update scripting when I`ll finish existing bugs from ispcp (if nobody else will come with a better version Wink ),

Won`t solve, only a fresh install of ispcp will help, but you must migrate existing accounts.

Hmmz this last script you gave me is nice, but I see I also mis .htgroup .htpasswd files in some virtual directories.
And who knows what else more.

I found out after the update script from you, new accounts are created perfectly again.

I found out only 4users have this problem.
Im going to backup, delete and re-create this users.

Also I will check all config files for changes.
I think it's easy since the files are all in trunk/configs/debian/
ohh yes before I forgot.
Thanks for your quick and great help! Wink
