Install ZabiRepo on CentOS 7

yum install git -y
cd /usr/share/zabbix/
sudo git clone "https://github.com/usiusi360/zabirepo.git"

Now go to:

http://ip.address.goes.here/zabbix/zabirepo

Was ist das?:

Invalid parameter "/": unexpected parameter "extendoutput".

One workaround (not recommended) is to open:

vi /usr/share/zabbix/include/classes/validators/CApiInputValidator.php

and search for keyword:

unexpected

Replace:

                // unexpected parameter validation
                foreach ($data as $field_name => $value) {
                        if (!array_key_exists($field_name, $rule['fields'])) {
                                $error = _s('Invalid parameter "%1$s": %2$s.', $path, _s('unexpected parameter "%1$s"', $field_name));
                                return false;
                        }
                }

With:

                // unexpected parameter validation
                //foreach ($data as $field_name => $value) {
                //      if (!array_key_exists($field_name, $rule['fields'])) {
                //              $error = _s('Invalid parameter "%1$s": %2$s.', $path, _s('unexpected parameter "%1$s"', $field_name));
                //              return false;
                //      }
                //}
