Use of uninitialized value in concatenation (.) or string at

[Eldaras Sad]

Hello,

I first run http://192.168.1.96/otobo/installer.pl

I get an error 500 Internal Server Error

Check log file /var/log/httpd/error_log

I view two errors:

Use of uninitialized value in concatenation (.) or string at /opt/otobo/Kernel/Output/HTML/Layout.pm line 1602.

Message: mkdir /opt/otobo/var/tmp/CacheFileStorable/TemplateProvider: Permission denied at /opt/otobo/Kernel/System/Cache/FileStorable.pm line 99.

FileStorable.pm permission is chmod 777

I don’t understand what file permission should be?

Message: mkdir /opt/otobo/var/tmp/CacheFileStorable/TemplateProvider: Permission denied at /opt/otobo/Kernel/System/Cache/FileStorable.pm line 99.

The problem is „/opt/otobo/var/tmp/CacheFileStorable/TemplateProvider“. Make sure you set the correct user/group on /opt/otobo and all subdirectories/files.

In case you’re using Debian/Ubuntu with Apache2, the correct user/group is chown -R otobo:www-data /opt/otobo

FileStorable.pm permission is chmod 777

Chmod 777 is not recommended, never trust everybody ;)

I installed OTOBO on CentOS 8

My actions:

root>useradd -r -U -d /opt/otobo -c ‚OTOBO user‘ otobo -s /bin/bash
root>usermod -G apache otobo
root>cp /opt/otobo/scripts/apache2-httpd.include.conf /etc/httpd/conf.d/zzz_otobo.conf
root>chown -R otobo:apache /opt/otobo

root>/opt/otobo/bin/otobo.SetPermissions.pl
Skipping /.github (maybe here problem?)

root>systemctl start httpd.service

The problem remains:

Can’t create directory ‚/opt/otobo/var/tmp‘:
Can’t create directory ‚/opt/otobo/var/tmp/CacheFileStorable‘: No such file or directory
mkdir /opt/otobo/var/tmp: Permission denied at /opt/otobo/Kernel/System/Cache/FileStorable.pm line 99.

CheckModules.pl all OK.

I uninstalled otobo and reinstalled it, but I still get the same error.

Is SELinux active?

[Eldaras Sad]

SELinux status: enabled
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: enforcing
Mode from config file: enforcing
Policy MLS status: enabled
Policy deny_unknown status: allowed
Memory protection checking: actual (secure)
Max kernel policy version: 33

I installed:
CentOS 8
Otobo 10.0.9
perl
epel-release
/opt/otobo/bin/otobo.CheckModules.pl -all program installed
MySQL
mysqltuner
java-1.8.0-openjdk-devel
elasticsearch

Out of despair, I installed everything to new, but I still get the same error.

Have you tried Otobo in Docker ? Works fine, hassle free.

[Eldaras Sad]

I will try to install OTOBO with the Docker. I hope everything works out.

[Eldaras Sad]

Finally succeeded :-) ,
after installing Docker launched the link: http://myip/otobo/installer.pl
Many thanks to everyone for the help.

I have problem in  step (2/4)

User: root
Password: MySQLrootpassword
Host: db

Can’t connect to MySQL server on ‚db‘ (115)

systemctl status mysqld.service (active)
I checked mysql -u root -p. It’s ok.

 

[Eldaras Sad]

systemctl stop firewalld.service
http://myserverip/otobo/installer.pl (2/4)
Database check successful.

systemctl start firewalld.service
Can’t connect to MySQL server on ‚db‘ (115)

firewall-cmd –zone=public –add-service=mysql –permanent
firewall-cmd –zone=public –add-port=3306/tcp –permanent
firewall-cmd –zone=public –add-source=myip
firewall-cmd –reload

my.cnf
#bind-address=0.0.0.0

I still get a mysql error 115

Maybe someone knows how to configure the firewall correctly to connect to mysql?

[Eldaras Sad]

I talked to myself :-)
Solution found:
firewall-cmd –zone = public –add-masquerade –permanent
