OTRS 5.0.9 CentOS installation - Internal Server Error

[danchitu86]

Hi all!

I did a fresh install of otrs-5.0.9-01.noarch.rpm on a CentOS 6.7 (tried both 32 and 64 bit). After following all the steps from the user guide http://otrs.github.io/doc/manual/admin/ ... -on-centos I can't access the installer at: http://172.18.7.21/otrs/installer.pl. It sais:

Code: Select all

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.

In /var/log/httpd/error_log I have:

Code: Select all

[Thu May 12 14:32:01 2016] [error] mkdir /opt/otrs/var/tmp/CacheFileStorable: Permission denied at /opt/otrs//Kernel/System/Cache/FileStorable.pm line 87\n

I don't know what to do next. Thank you!

Fix the permissions and check if SELinux is permissived or disabled.

Thank you, SELinux was the issue. Maybe it is a good idea to add this to the user guide. CentOS 6.7 had this enabled by default.

I have now some slow performance issue - the webpages are not loading as fast as my old instance (OTRS 3.2.3 installed on Windows).
I have check in Support Data Collector and everything is green, except:

Code: Select all

mod_filter Usage (not active)
Please install mod_filter if mod_deflate is used.

What else can I check?

Thank you!

If you have mod_filter installed you should see this line within /etc/httpd/conf/httpd.conf

Code: Select all

# LoadModule filter_module modules/mod_filter.so

just remove the # for comment and then restart your apache, it should be enough.

On my system (CentOS 6.x) I installed the following packages related to apache:

Code: Select all

yum install httpd-devel httpd-devel.i686 "perl(Apache::DBI)"

To list the modules presently installed on your apache you may run the following command:

Code: Select all

apachectl -t -D DUMP_MODULES

[root]

Add mod_perl, this is available via EPEL (yum install epel-release).

[danchitu86]

Thank you both! Now mod_filter Usage in active and webserver is working faster!

One short off topic question: How can I find all settings from Admin>System Administration>SysConfig that are not default? I want to check my settings from the old instance I want to replace (v3.2.3) and set them on 5.0.9. Thanks!
