A note about the PHP session and the recommended Redis session

[koenigswinter]

Hi! Thanks for the good tutorial reference. Session handling via Redis works fine on my instance 👍 . Did you also manage to get the redis authentication to work? I tried the following settings (Ubuntu 16.04.1):

1. /etc/redis/redis.conf
   requirepass <mySuperSecretPassword>
2. /etc/php/7.0/apache2/php.ini

session.save_handler = redis
session.save_path = "tcp://127.0.0.1:6379?auth=<mySuperSecretPassword>"

3. MISP Server Settings

Plugin settings --> ZeroMQ
Plugin.ZeroMQ_redis_host => 127.0.0.1
Plugin.ZeroMQ_redis_port => 6379
Plugin.ZeroMQ_redis_password => <mySuperSecretPassword>
Plugin.ZeroMQ_redis_database => 1
Plugin.ZeroMQ_redis_namespace => mispq

However, after restarting Apache & Redis, I can't access https://misp.example.com/servers/serverSettings/ anymore and receive the following error in /var/www/MISP/app/tmp/logs/error.log:

Do you have to set the Redis password anywhere else? Cheers

@koenigswinter I'm running into the same issue. Did you find a solution workaround?

File app/Plugin/CakeResque/Config/config.php
$config['CakeResque'] = array(
'Redis' => array(
'host' => 'localhost', // Redis server hostname
'port' => 6379, // Redis server port
'database' => 0, // Redis database number
'namespace' => 'resque', // Redis keys namespace
'password' => null // Redis password
),

After change 'password' to mysecretpass, it fix problem
