Memcaching crashes NC17

[Traffle]

Hi All,

This is for a brand new fresh install of NC17.0.1 on a Ubuntu18.04 LNMP server

I have installed acpu, memcached and redis. I have edited my php.ini file

Everytime I try to enable memcached or redis on my config.php, and restart nginx, NC crashes

Here is my config file:

  'memcache.local' => '\OC\Memcache\APCu',
#  'memcache.distributed' => '\OC\Memcache\Memcached',
#  'memcache.local' => '\\OC\\Memcache\\Redis',
#    'memcache.locking' => '\\OC\\Memcache\\Redis',
#    'redis' =>
#     array (
#      'host' => '/var/run/redis/redis.sock',
#      'port' => 6379,
#      'timeout' => 0,
#      'password' => '',
#      'dbindex' => 0,
#  ),

Here is the server status on each one:

root@file:/etc/php/7.3/mods-available# ps ax | grep redis
25747 ?        Ssl    0:01 /usr/bin/redis-server 127.0.0.1:6379
28173 pts/0    S+     0:00 grep --color=auto redis
root@file:/etc/php/7.3/mods-available# ps ax | grep memcache
23818 ?        Ssl    0:00 /usr/bin/memcached -m 64 -p 11211 -u memcache -l 127.0.0.1 -P /var/run/memcached/memcached.pid
28175 pts/0    S+     0:00 grep --color=auto memcache
root@file:/etc/php/7.3/mods-available# ps ax | grep acpu
28177 pts/0    S+     0:00 grep --color=auto acpu
root@file:/etc/php/7.3/mods-available# 

Can someone guide me on getting Redis working with NC

Can someone guide me on getting Redis working with NC

IMHO avoid memcached if the other two are around (which is the preferred solution).

Have a look at:

Memory cache for shared hosting

For the benefit of the discussion and of the general public: Server-Tuning 4: OPcache, APCu, memcache, memcached Redis vs APCu 2018 Ref NC 16 Docs » Nextcloud configuration » Memory caching Nextcloud supports multiple memory caching backends, so you can choose the type of memcache that best fits your needs. The supported caching backends are: APCu, APCu 4.0.6 and up required. A local cache for systems. Redis, PHP module 2.2.6 and up required. For local and distributed caching as wel…

• NC 17 Docs » Nextcloud configuration » Memory caching
• You may have better performance when using Un*x sockets instead of the network port for redis-server locally on the same machine.

Hope this helps.

‘redis’ =>
array (
‘host’ => ‘/var/run/redis/redis.sock’,
‘port’ => 6379, # ‘timeout’ => 0,
‘password’ => ‘’,
‘dbindex’ => 0,
),

Please make sure that the redis.conf file contains at least the following line:

unixsocket /var/run/redis/redis.sock

Check the ownership and file access rights of the Redis socket:

ls -al /var/run/redis/redis.sock

Change the Redis configuration as follows:

'memcache.locking' => 'OC\\Memcache\\Redis',

'redis' => array (
   'host' => '/var/run/redis/redis.sock',
   'port' => 0,                                # <<< !!!
   'timeout' => 0.0
),

“Memcached” (distributed) is normally not required for a local installation.

Thank you sooooooo much for your help

I don’t have a /var/run/redis/redis.sock file, the only file in that folder is redis-server.pid

I forgot to give ownership to the redis folder.

It is up and running now,

Thank you again, j-ed
