Unable to reactivate Redis after disabling

Support and Discussion General Discussion

Hello,

Redis is giving me problems I have looked all over the internet and tried many solutions but it still does not work for me.

  • Centos 7
  • Cyberpanel + Openlitespeed
  • 48 GB Ram
  • 12 Core Xeon Processor

1 x Wordpress site on php 7.4, CPU & Ram was hitting the roof, fan doing overdrive! Restarting php would resolve issue for a few minutes until it reoccurred.

Switching to php 7.3 seems to have solved the issue but site has worked perfectly fine on 7.4 until now, so what could be the issue here?

Anyway I removed Redis deamon from Cyberpanel 1 click installer to see if the issue still occurred as I suspected database and php, issue remained.

I tried to reinstall Redis daemon from Cyberpanel 1 click installer and it seems to install without any error but it will not activate or connect.

Try

yum erase redis
yum install redis

see if you can start redis then?

Thank you,

After running those Litespeed plugin said Redis was now enabled, so I enabled object cache option then site stopped responding. Seems connection still fails.

Installed:
redis.x86_64 0:3.2.12-2.el7

Complete!
[root@mail ~]# systemctl start redis
[root@mail ~]# systemctl enable redis
Created symlink from /etc/systemd/system/multi-user.target.wants/redis.service to /usr/lib/systemd/system/redis.service.
[root@mail ~]#

When I check Redis status it still says failed.

[root@mail /]# service redis status
Redirecting to /bin/systemctl status redis.service

Check with redis guys, not specifically related to CyberPanel or any bug from our end.
