RoundCube not using Redis.

[Amplificator]

Hey.

I'm having an issue getting RoundCube to use Redis. Redis is supported by the server and I have a test script that simply logs the number of times that I have visited the site and it works just fine using the same connection info I have given RoundCube.

For RoundCube I have added the following to my config file:

Code Select Expand

$config['redis_hosts'] = 'localhost:7035:0:PASSWORD';
$config['redis_max_allowed_packet'] = '8M';

Host, port, database id and password is correct, and as I said it works in my php test script which is on the same domain as RoundCube - have I missed something?
RoundCube shows nothing in its errors.log file.

Doing "redis-cli monitor" on the same host, port and password as I've given both RoundCube and the test script shows nothing when RoundCube is in use. I can see changes from the test script just fine.

It does not use Redis by default, you have to enable session/caches for use with Redis.

I assume you mean I need to add this as well:

Code Select Expand

$config['session_storage'] = 'redis';

When doing so RoundCube won't load and in RoundCubes own error.log file I get these errors:

Code Select Expand

I am absolutely certain that Redis is running and working with the host, port, database id and password I put in the config file. I can monitor the database using redis-cli and see the test script use it as well.

Did I miss another thing?

[JohnDoh]

$config['redis_hosts'] = 'localhost:7035:0:PASSWORD';

should be

$config['redis_hosts'] = ['localhost:7035:0:PASSWORD'];

i think, according to the examples in comments of the config file.

Hey, that worked - thanks

It does state in the comment above that "Currently only one host is supported" so I somehow disregared the brackets and just had it as a single string. I guess that was my own fault

I do see the Redis database being used now.

Thank you, @JohnDoh
