Resolved Redis as docker for nextcloud

[djimno]

Hello,

i have start redis as docker. Now i want to use this to accelate my nextcloud.

First i type in a terminal

ps ax | grep redis
20605 ?        Ssl    0:03 redis-server *:6379

When i add to the config-file in nextcloud

'memcache.distributed' => '\OC\Memcache\Redis',
'memcache.locking' => '\OC\Memcache\Redis',
'memcache.local' => '\OC\Memcache\APCu',
'redis' => array(
     'host' => 'localhost',
     'port' => 6379,
      ),

i get the error:

Memcache \OC\Memcache\APCu not available for local cache Is the matching PHP module installed and enabled?

If i change '\OC\Memcache\APCu' in '\OC\Memcache\Redis' i get only a blank site.

Can someone help me?

Thx
Martin

[EDIT]
I install now APCu so i get no error like this:

Memcache \OC\Memcache\APCu not available for local cache Is the matching PHP module installed and enabled?

Now i get this error:

[EDIT2]
The problem was solved by uncomment this line:

# 'memcache.distributed' => '\OC\Memcache\Redis',
'memcache.locking' => '\OC\Memcache\Redis',
'memcache.local' => '\OC\Memcache\APCu',
'redis' => array(
     'host' => 'localhost',
     'port' => 6379,
      ),
