Nextcloud version (18.0.1):
Operating system and version (Ubuntu 16.04.6 LTS):
Apache or nginx version (Apache 2.4.18):
PHP version (7.3):
The issue you are facing:
I setup a new instance of next cloud and started following the security and setup suggestion on the Admin>Overview page.
One of the reccomendations was: No memory cache has been configured. To enhance performance, please configure a memcache, if available. Further information can be found in the documentation.
So I read the docs and then found this guide: https://www.techrepublic.com/article/how-to-enable-caching-on-nextcloud-16/
I reached the last step of editing the config.php and encountered this error when refreshing the page: Internal Server Error
The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.
Originally I discovered that the /var/run/redis/redis.sock file was missing but I used the steps found here to resolve that problem: [PHP] Error: Redis::connect(): connect() failed: No such file or directory at /var/www/nextcloud/lib/private/RedisFactory.php#90
The file now exists but I still get the internal server error when browsing to the page.
If I remove the following from the config.php it works again:
'memcache.local' => '\\OC\\Memcache\\Redis',
'memcache.locking' => '\\OC\\Memcache\\Redis',
'redis' =>
array (
'host' => '/var/run/redis/redis.sock',
'port' => 0,
'timeout' => 0,
'password' => '',
'dbindex' => 0,
)
I have been through numourous community articles here and elsewhere trying to resolve it to no avail.
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Fresh Install of NExtcloud
- install Redis using this link: https://www.techrepublic.com/article/how-to-enable-caching-on-nextcloud-16/
- Upon last step in changing config.php I receive internal server error
The output of your Nextcloud log in Admin > Logging: I only included the last line as there are 14k lines in the log. Which may point to a bigger problem, haha.
