Redis Extension Bug - Upgrade needed

See original GitHub issue

What version of the buildpack you are using? v4.3.79 - v4.3.82

If you were attempting to accomplish a task, what was it you were attempting to do? Using the included Redis extension to connect to a Redis Cluster

What did you expect to happen? Successful connection to Redis

What was the actual behavior? Exception thrown stating “No such file or directory”

No such file or directory {"exception":"[object] (RedisException(code: 0): No such file or directory at /home/vcap/app/vendor/laravel/framework/src/Illuminate/Redis/Connectors/PhpRedisConnector.php:120)

Reproduction steps:

  • Setup a Redis connection using the PhpRedis ( extension using a port > 32768

Reason: With the release of PHP Buildpack v4.3.79 the PhpRedis extension was upgraded to v5.0.1. But this release of the extension contains a bug which prevents connecting to Redis using a port greater than 32768. See

Our CF provider uses Redis port 49948 which means we have to stick with the buildpack version v4.3.78 and cannot benefit from PHP 7.3.9 and the various improvements of PhpRedis.

Recommendation: Upgrade PhpRedis extension to v5.0.2 to fix this. Additionally this will make the extension ready for PHP 7.4.

This can be closed, 4.4.0 with the fix has been released. ✨

If you don’t depend on PhpRedis 5.0 you can write a custom extension which replaces with the version from v4.3.78:

"""Replace PHP redis module

Replaces the with the one from php7-7.3.6-linux-x64-cflinuxfs3-1a76a4dd.
import os
import os.path
import logging
from build_pack_utils import utils
import shutil

_log = logging.getLogger('php-redis')

# Extension Methods
def preprocess_commands(ctx):
    return ()

def service_commands(ctx):
    return {}

def service_environment(ctx):
    return {}

def compile(install):
    print 'Replacing PHP redis module'

    ctx = install.builder._ctx
    dest   = os.path.join(ctx['BUILD_DIR'], 'php', 'lib', 'php', 'extensions', 'no-debug-non-zts-20180731', '')
    source = os.path.join(ctx['BUILD_DIR'], '.extensions', 'php-redis', '')
    shutil.copy(source, dest)

    return 0
