    Hi,

    I have tried to configure the plugin to use Redis with unixsocket

    I have specified as HOST: /var/run/redis/redis.sock
    Port 0

    Also, I have tried to leave Port empty.

    When I click save I get in the debugs:

    I’m able to connect in the server without a problem:

    [root@himaxweb wp-content]# redis-cli -s /var/run/redis/redis.sock
    redis /var/run/redis/redis.sock> monitor
    OK

    I can only use Redis TCP as seen below.

    Is it supported to use Redis unixsocket? If yes, could you please let me know what I’m missing or how can be debugged?

    Thank you,
    Best Regards

    Hi,

    Please make sure that you have set port to 0 when you use socket

    Hi,

    Please run it by URL ,like https://domain.com/script1.php

    when you run it by root , the PHP runs as root , while being root , it has access to everything.

    You need to run it as your site’s PHP user does.

    Hi @qtwrk,

    Thank you for pointing me to the right direction 🙂

    I created a templated using the script and I got a permission denied so you are right, access to /var/run/redis/redis.sock was own by redis:redis so I change it to redis:nobody Now it works perfectly.

    Thank you!

    Hi,

    A better approach is to set Redis run as same user as PHP user ,

    I think make sock by nobody group might not be good idea for security as nobody user can read it which could be a security vulnerability

    Hi @qtwrk

    I agree with you 🙂

    I will configure now PHP SuEXEC.

    Thank you once again.
