I’ve been doing the installation of IcingaDB Web as documented but upon the lasts steps where you add the Database to the module icingadb.
Documentation for reference: IcingaDB Web Installtion
My first error was this:
Uncaught Error: Class 'Redis' not found in /usr/share/icingaweb2/modules/icingadb/library/Icingadb/Common/IcingaRedis.php:92
Stack trace:

But with installing php-redis first that went away and gave me other errors.
I cant see the menu bar anymore since this error is covering it:
Fatal error: Declaration of Icinga\Module\Icingadb\Model\Behavior\ReRoute::rewriteCondition(Icinga\Data\Filter\FilterExpression $expression, $relation = NULL) must be compatible with ipl\Orm\Contract\RewriteFilterBehavior::rewriteCondition(ipl\Stdlib\Filter\Condition $condition, $relation = NULL) in /usr/share/icingaweb2/modules/icingadb/library/Icingadb/Model/Behavior/ReRoute.php on line 19
In another discussion I found that you will need RC2 but after some research I knew I had that.
After all of this and trying other ways and methods I found that my icingadb-redis would not be able to be enabled, which is said to be done here.
The error message:
# systemctl enable icingadb-redis
Failed to enable unit: Refusing to operate on alias name or linked unit file: icingadb-redis.service
I really don’t know where to start or what exactly could be the problem. Would be nice if someone could help me out here. I’m working on a Debian system
