You permissions are incorrect: run the /opt/otrs/bin/otrs.SetPermissions.pl script with appropriate arguments for your environment (can be found in the INSTALL file).

[jresz]

The script was run successful, with no error. This is why I don't understand it why I get this error.

You get this error because you provided/didn't provide the proper user and group names to the params.

From INSTALL:
Web server which runs as the OTRS user:

Code: Select all

bin/otrs.SetPermissions.pl --otrs-user=otrs --web-user=otrs /opt/otrs

Webserver with wwwrun user (e. g. SUSE):

Code: Select all

bin/otrs.SetPermissions.pl --otrs-user=otrs --web-user=wwwrun /opt/otrs

Webserver with apache user (e. g. Red Hat, CentOS):

Code: Select all

bin/otrs.SetPermissions.pl --otrs-user=otrs --web-user=apache --otrs-group=apache --web-group=apache /opt/otrs

Webserver with www-data user (e. g. Debian, Ubuntu):

Code: Select all

bin/otrs.SetPermissions.pl --otrs-user=otrs --web-user=www-data --otrs-group=www-data --web-group=www-data /opt/otrs

[jresz]

bin/otrs.SetPermissions.pl --otrs-user=otrs --web-user=apache --otrs-group=apache --web-group=apache /opt/otrs
bin/otrs.SetPermissions.pl <1.4> - set OTRS file permissions

And i get the same error at the login

[crythias]

what are the permissions on /opt/otrs/var/tmp ?
It may be possible that you are running apache as a user different than www-data.

[jresz]

I use Centos linux,
ls -l /opt/otrs/var/
total 64

[crythias]

ps -eo user,command | grep apache
and verify this (first column is the user running apache)

drwxrwsr-x. 3 otrs apache 4096 Sep 26 08:14 tmp

I'm not entirely certain but I have a feeling it may be because of selinux enabled.

[jresz]

ps -eo user,command|grep apache

[crythias]

how about selinux?
sestatus

[jresz]

Hi,

sestatus
SELinux status: enabled
SELinuxfs mount: /selinux
Current mode: enforcing
Mode from config file: enforcing
Policy version: 24
Policy from config file: targeted

[crythias]

yep. as I've stated, and as well as the install docs, disable selinux.

[hemangc]

Hi crythias,

Hope you are doing well.

I just read the thread and i am facing the same issue while updating OTRS from 2.4.15 to 3.0.1. in my environment we are using CentOS with SELinux Disabled mode. The otrs is successfully migrated with themes but when i access Web, i get below error message which i attached here as file name Browser.

Initially there was nogroup assign/define in /opt/otrs/var/tmp/CacheFileStorable/ but then i added apache group in it. but no success. i also run below command to set proper permissions in /opt/otrs directory with below command

/opt/otrs/bin/otrs.SetPermissions.pl --otrs-user=otrs --web-user=apache --otrs-group=apache --webgroup=apache /opt/otrs

but that would not work.

Please help me to get this resolved as we are planning to update otrs to its latest version (otrs 5).


Thanks & Best Regards,
Hemang Chhipani
