Unable to configure REDIS caching

Recommended Posts

Hello all

I am having a very tough time to properly setup REDIS as a cache for prestashop. 

Some info:

  • OS Ubuntu 18.10 Cosmic
  • PHP Version 7.3.0
  • Apache 2.4.37
  • Prestashop 1.7.5
  • MySQL  5.7.20-18-18-log (Percona)

Installed redis-server and redis-client as per online tutorial (https://www.digitalocean.com/community/tutorials/how-to-set-up-a-redis-server-as-a-session-handler-for-php-on-ubuntu-14-04)  made sure i got latest redis versions/distrosredis.conf configured with the following line:

bind 0.0.0.0

(tried with password also and without --i.e uncommenting and commenting

requirepass yourverycomplexpasswordhere

 

php.ini file configs:

session.save_handler=redis
session.save_path="tcp://127.0.0.1:6379"

extension=redis.so
 

redis server restarted.

Apache restarted

prestashop gives me a 500 error.

php_error_log file shows:

[19-Jan-2019 20:38:10 Asia/Beirut] PHP Warning:  session_start(): Cannot find save handler 'redis' - session startup failed in /opt/lampp/htdocs/merkado/vendor/symfony/symfony/src/Symfony/Component/HttpFoundation/Session/Storage/NativeSessionStorage.php on line 145

when i comment the redis related lines in php.ini and revert to 

session.save_handler=files
 

prestashop works again. 

Can anyone please help?
