    Hi,

    I am (yet another person!) having trouble with W3TC and Redis. WordPress and Redis are on the same server.

    I have:
    – installed and verified that Redis is running (ping/pong).
    – installed phpredis and verified with php -r "if (new Redis() == true){ echo \"OK \r\n\"; }"
    – followed the FAQ and added db-config.php in the plugin ini folder with (taken from the sample in the same dir):

    
<?php

define( 'W3TC_CONFIG_CACHE_ENGINE', 'redis');
define( 'W3TC_CONFIG_CACHE_REDIS_SERVERS', '127.0.0.1:6379' );

    The Redis option is still disabled and I am not sure where to look next.

    Hello @bradman334

    I am sorry about the issue you are having with activating Redis and I am happy to assist you with this.
    Just to make sure, have you followed these instructions on how to install PHP Redis?
    Have you tried restarting your webs server?

    Hi Marko,

    I haven’t followed them explicitly because the phpredis module was already installed in our apache server. I can confirm it using phpinfo() in a php file in our theme.

    I also tried putting the following in the file:

    <?php

// Connecting to Redis server on localhost
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
echo "Connection to Redis server successful<br />";
echo "Server is running: ".$redis->ping();

phpinfo();

?>

    The output is:

    
Connection to Redis server successful
Server is running: 1

phpinfo output...

    Hello @bradman334

    Have you tried to restart your web server and check if you can select redis after that?

    You need to install, using the apt-get install redis-server, redis-tools and php-redis and in the config for redis check out IP and port.

    Restart web server – apache.
    Validate it you can see it in phpinfo().
    Try the button “Test” in W3TC settings page for redis – if successfull, great it’s working.

    I did not needed to custom write into files db, advanced-cache, object-cache.

    Just copy them from the plugin’s /wp-content/ to your /wp-content/ folder.

    Hi Marko. I was hoping to avoid a restart. It doesn’t seem right that a WordPress plugin would require a restart for a feature to become enabled. But in the absence of any other solution I can schedule a quiet time to try it.

    Tomislav, read my last reply and you will see that I have done all the things you suggest including verifying it with phpinfo() and making a call to Redis from php code.

    The good news is that I restarted the server and now I can select Redis. Thanks Marko.
