Hi,

The Solution

1)Create a file, index.html , and placed it in /var/www/html
It does not matter what the contents of the file are...it just has to be there.

2)Some time your selinux will cause the issue so you need to deactivate the selinux.
3)Some time File permission will also cause the issue.
You can change the file permission using following command, go to that directory and run following command.
#chmod 777 *

Or access this link http://administrator-server.blogspot.in ... os-64.html and start new installation.

Hi,
just some other hints ...
Disable Linux firewall:

Code: Select all

service iptables save
service iptables stop
chkconfig iptables off
service ip6tables save
service ip6tables stop
chkconfig ip6tables off

Disable selinux, edit file /etc/selinux/config and set:

Code: Select all

SELINUX=disabled

Please, note that this is really important, since unless you disable selinux /opt/otrs/Kernel/Config.pm cannot be edited and you won't be able to run your installer.pl

Check and enable the runlevels of apache:

Code: Select all

chkconfig httpd on

http-devel should be installed also afaik ...

Code: Select all

yum install httpd-devel
yum install httpd-devel.i686

Check if all the required components of mySql are correctly installed:

Code: Select all

yum list mysql-server mysql php-mysql

and enable the runlevels for mysqld

Code: Select all

chkconfig --levels 235 mysqld on

You should run also /usr/bin/mysql_secure_installation at the end of the mySql installation

Finally you should check if the required perl libraries are all installed:
run /opt/otrs/bin/otrs.CheckModules.pl
to extract it from the rpm you may use:

Code: Select all

rpm2cpio otrs-3.2.7-01.noarch.rpm | cpio -id ./opt/otrs/bin/otrs.CheckModules.pl

Right after OTRS has been installed you should go through a restart of the services and a reset of the file permissions...

Code: Select all

service otrs stop
service crond stop
service httpd stop
service mysqld stop
service mysqld start
/opt/otrs/bin/otrs.SetPermissions.pl --otrs-user=otrs --web-user=apache --otrs-group=apache --web-group=apache /opt/otrs
service httpd start
service crond start
service otrs start

Or, if you actually care about SELinux, you can use this policy I just wrote. The obvious problems are OTRS is running under the user "apache" as type "httpd_t" because of mod_perl and needs write access to usr_t, bin_t (why?!), so the right solution would be moving it to something like FastCGI under a separate user, setting the contexts on all files (especially /opt/otrs/var/tmp have to be created and fixed manually, "cron/" has to be usr_t, but "CacheFileStorable/" has to be httpd_t) and creating some type like "otrs_t" instead of plain httpd_t.

The basic policy code is below, here are the instructions to apply:

Code: Select all

## for the connection to database server
# setsebool -P httpd_can_network_connect=on

$ vi otrs.te
$ checkmodule -M -m otrs.te -o otrs.mod
$ semodule_package -o otrs.pp -m otrs.mod
# semodule -i otrs.pp

Code: Select all

module otrs 1.0;

require {
        type bin_t;
        type fs_t;
        type httpd_t;
        type unconfined_t;
        type user_tmpfs_t;
        class dir { add_name create read remove_name write };
        class file { create read setattr unlink write };
        class filesystem { associate };
        class shm { associate getattr read unix_read unix_write write };
}

allow httpd_t bin_t:dir add_name;
allow httpd_t bin_t:dir remove_name;
allow httpd_t bin_t:dir write;
allow httpd_t bin_t:file create;
allow httpd_t bin_t:file unlink;
allow httpd_t bin_t:file write;
allow httpd_t fs_t:filesystem associate;
allow httpd_t httpd_t:dir add_name;
allow httpd_t httpd_t:dir create;
allow httpd_t httpd_t:dir read;
allow httpd_t httpd_t:dir remove_name;
allow httpd_t httpd_t:dir write;
allow httpd_t httpd_t:file create;
allow httpd_t httpd_t:file setattr;
allow httpd_t httpd_t:file unlink;
allow httpd_t user_tmpfs_t:file read;
allow httpd_t user_tmpfs_t:file write;
allow httpd_t unconfined_t:shm associate;
allow httpd_t unconfined_t:shm getattr;
allow httpd_t unconfined_t:shm read;
allow httpd_t unconfined_t:shm unix_read;
allow httpd_t unconfined_t:shm unix_write;
allow httpd_t unconfined_t:shm write;
