Not sure what i am missing to resolve this? Any recommendations would be much appreciated.

Thanks

in what log are those errors?

 

[Rockforduk]

Apache logs

 

[quietFinn]

I've seen those errors several times and usually it's caused by a line in some user's php.ini file, but Apache error log doesn't tell the user.
There is no referer in any of those error lines?

No unfortunately

 

[andrew.n]

Do you see the same if you type "php -v" for example?

 

[Damian]

I am also seeing the same error repeated in the apache error_log.

Current cPanel (stable), CloudLinux CentOS7, EA-PHP74. No references to redis in ini files in the account. And it's not unique to this single account, it's occurring across all users.

Any suggestions on where to look?

 

[andrew.n]

@Damian: do you see this under "php -v" via SSH as root? If yes you can do "php --ini" then based on the ini file path do:

grep -r redis /etc/path

to show if reference to redis is shown up there multiple times. Please paste here the outputs.

 

[Damian]

Thanks @andrew.n I didn't see it appear with php -v but after some digging around in /opt/cpanel/ea-php74/root/ I found two reference to redis.so

./etc/php.d/redis.ini:1:extension=redis.so
./etc/php.d/50-redis.ini:2:extension = redis.so

So I commented it out of 50-redis.ini and restarted apache.

I haven't seen the error since and redis appears to be working fine on the site that it was installed for. Now I need look into how to have each user (cPanel) have their own instance of redis to avoid collisions and potential security issues.

 

[andrew.n]

Good job. There are some Redis plugins out there which you can also try like the one from Unixy or this one:

GitHub - RSOHosting/cpanel_redis: Redis plugin for cPanel

Redis plugin for cPanel. Contribute to RSOHosting/cpanel_redis development by creating an account on GitHub.

github.com

though all seems to be quiet outdated

 

[Damian]

Thanks Andrew, that looks like a good place to start.

 

[upsforum]

stay away from this site (unixy.net), i bought two weeks ago, no links, no software, no answers, i opened dispute on paypal

 

[andrew.n]

Sadly unixy is out of business for a bit now
