Description

I'm trying to configure cluster with php7.0 and redis.
I installed redis server and redis extensions for php7

My cluster configuration is set with 4 servers as:

Server1(Varnish in round robin) -
Server2 (ezdfs1)(with ezplatform) -> 10.0.5.2
Server3 (ezdfs1)(with ezplatform) -> 10.0.5.3
Server4 (with MariaDB DB) - 10.0.5.4

My redis server on server2 (10.0.5.2), so I configured /etc/redis/redis.conf to accept all interfaces, commenting the "bind" line:

# bind 127.0.0.1

Regarding sessions, I have in php.ini:

session.save_handler = redis
session.save_path = "tcp://10.0.5.2:6379" ;sessions are kept in first server

And I have my ezplatform set as:

zpublish:
    # Repositories configuration, setup default repository to support solr if enabled
    repositories:
        default:
            storage: ~

                        port: 6379

in the first server, where I have the redis server installed, when doing redis-cli monitor, i can see that redis server is working

1468840211.117536 [0 10.0.5.3:50146] "GET" "4df4fa77cab7a7627564bd0e86e0673f"

But when trying to access one of my installations, i have in app/logs/prod.log error:

[2016-07-18 13:00:56] request.CRITICAL: Uncaught PHP Exception RedisException: "Connection closed" at /var/www/html/ezplatform/vendor/tedivm/stash/src/Stash/Driver/Redis.php line 270 {"exception":"[object] (RedisException(code: 0): Connection closed at /var/www/html/ezplatform/vendor/tedivm/stash/src/Stash/Driver/Redis.php:270)"} []
