Title: Status: Not connected Last modified: February 26, 2017 --- # Status: Not connected * Resolved Anonymous User 7326277 * (@anonymized-7326277) * [9 years, 1 month ago](https://wordpress.org/support/topic/status-not-connected/) * I have this weird issue after changing way plugin connects to the Redis. I’ve placed following two entries in wp-config.php file: * ``` define( 'WP_REDIS_SCHEME', 'unix' ); define( 'WP_REDIS_PATH', '/var/run/redis/redis.sock' ); ``` * When checking status via wp-cli utility I’m getting following result: * ``` $ wp redis status Status: Connected Client: PECL Extension (v3.0.0) ``` * But in website interface it says: * `Not Connected` * Any ideas or suggestions what to check?

That is my report in fact, when using tcp and connecting via 127.0.0.1 it works flawlessly. If I bind redis to some other local IP and point redis plugin to it or use unix socket it results in situation mentioned in first post. * Plugin Author [Till Krüss](https://wordpress.org/support/users/tillkruess/) * (@tillkruess) * [9 years, 1 month ago](https://wordpress.org/support/topic/status-not-connected/#post-8850451) * I’d suggest just using `tcp`, or trying `unix` with Predis instead of PhpRedis. * Thread Starter Anonymous User 7326277 * (@anonymized-7326277) * [9 years, 1 month ago](https://wordpress.org/support/topic/status-not-connected/#post-8850460) * Any idea then why, when using tcp with any other IP other than 127.0.0.1 I get completely same situatioN? * [blindpet](https://wordpress.org/support/users/blindpet/) * (@blindpet) * [9 years, 1 month ago](https://wordpress.org/support/topic/status-not-connected/#post-8850474) * To answer your other question about IPs I would assume it is a firewall issue, you can list your iptable rules with `iptables -L` * Thread Starter Anonymous User 7326277 * (@anonymized-7326277) * [9 years, 1 month ago](https://wordpress.org/support/topic/status-not-connected/#post-8850485) * Redis is listening on a socket with permissions 770, ownership is redis:redis and user under which site is running is in redis group so it should be able to access it normally. * Tried switching to predis but seems like it is not working: * Client: PECL Extension (v3.0.0) WP_REDIS_CLIENT: “predis” * Regarding IPTables, I’m not using Linux in this case so IPTables is not used, but to answer the question, firewall is not blocking access. * [blindpet](https://wordpress.org/support/users/blindpet/) * (@blindpet) * [9 years, 1 month ago](https://wordpress.org/support/topic/status-not-connected/#post-8850490) * That is very likely your problem @ivantomica I suggest you check out that link I posted before. Unless your php handler (php-fpm or apache) is running as the redis user or group then access will be denied. * You can do a quick test with chmod 777 on the unix socket and re-test. * Thread Starter Anonymous User 7326277 * (@anonymized-7326277) * [9 years, 1 month ago](https://wordpress.org/support/topic/status-not-connected/#post-8850535) * Tried that [@blindpet](https://wordpress.org/support/users/blindpet/) , same issue. * [blindpet](https://wordpress.org/support/users/blindpet/) * (@blindpet) * [9 years, 1 month ago](https://wordpress.org/support/topic/status-not-connected/#post-8850538) * Please share the php handler you are using and the user name it runs under (netstat- lntp).
