PhpRedis was not compiled with Zstandard compression support

SupermanInNY · 2025-05-06T16:40:02-0600

Hi all,

I'm trying to migrate a wordpress to my server, and I see and error in the log files:

Got error 'PHP message: objectcache.critical: Failed to initialize object cache: PhpRedis was not compiled with Zstandard compression support, see For more information about enabling compressions see: https://objectcache.pro/docs/data-encoding/', referer: https://www.mda-kapam.org/

When I run:

# php -i | grep -i zstd
Registered PHP Streams => https, ftps, compress.zlib, php, file, glob, data, http, ftp, phar, zip, compress.zstd
ZSTD => No
ZSTD compression => No
zstd
Zstd support => enabled
zstd.output_compression => Off => Off
zstd.output_compression_dict => no value => no value
zstd.output_compression_level => -1 => -1

How do I enable the compression support?

thanks for any pointers.

-Sup.

Dit you try this already?

Code:

da build set_php "zstd" yes
da build "php_zstd"

/root # da build set_php "zstd" yes
php_zstd is already set to yes

try install "libzstd-devel" from "dnf" or "apt" and re-build "php_zstd" and "php_redis" again.

Hello,

You might use the custom script for building Redis with ZSTD support:

Bash:

cd /root/
wget https://raw.githubusercontent.com/poralix/directadmin-utils/master/php/php-extension.sh -O php-extension.sh
chmod 750 php-extension.sh
./php-extension.sh

then run

Bash:

./php-extension.sh install redis

for testing run:

Bash:

php -i | grep -i "^Redis Support" -A 5

you would see something like:

Bash:

#Redis Support => enabled
Redis Version => 6.2.0
Redis Sentinel Version => 1.0
Available serializers => php, json
Available compression => lzf, zstd

where the line Available compression => lzf, zstd should prove you have zstd support enabled.

p.s. If you don't want to use the script you will need to build PHP Redis with PECL manually. The link that can be found in your starting post contains instructions.

I tried it already.. I re-built everything again and again (from custombuild) before/after attempting to install libzstd-devel.

/root # php -i | grep -i zstd
Registered PHP Streams => https, ftps, compress.zlib, php, file, glob, data, http, ftp, phar, zip, compress.zstd
ZSTD => No
ZSTD compression => No
zstd

zstd.output_compression => Off => Off
zstd.output_compression_dict => no value => no value
zstd.output_compression_level => -1 => -1

/root # yum install libzstd-devel

Dependencies resolved.
Nothing to do.
Complete!

My pleasure. If you install Redis with DirectAdmin/CustomBuild you might loose ZSTD support in Redis. So you will need to stick to the custom script.

While I'm having this issue resolved,. the next one comes up:

Got error 'PHP message: objectcache.critical: Failed to initialize object cache: PhpRedis was not compiled with igbinary support. 'For more information about enabling serializers see: https://objectcache.pro/docs/data-encoding/'

I followed the same steps as with zstandard:

also did the steps from: https://forum.directadmin.com/threads/redis-install.64210/

/root # php -i | grep -i igbinary
igbinary
igbinary support => enabled
igbinary version => 3.2.16
igbinary APCu serializer ABI => no
igbinary session support => yes
igbinary.compact_strings => On => On
Registered serializer handlers => php_serialize php php_binary igbinary

but. I still get the PhpRedis was not compiled with igbinary support
And I'm not sure what I need to do now.

Probably something like: ./configure --enable-redis-igbinary needs to be pushed somewhere and then build? Or am I wrong?
I tried to rebuild php also from CustomBuild (also marked php_igbinary as Yes).

I'm still with this error.

any pointers on that?

Run

Bash:

cd /root
./php-extension.sh selfupdate
./php-extension.sh install igbinary
./php-extension.sh install redis

That should do a trick:

Bash:

# php -i | grep igbinary
igbinary
igbinary support => enabled
igbinary version => 3.2.16
igbinary APCu serializer ABI => no
igbinary session support => yes
igbinary.compact_strings => On => On
Available serializers => php, json, igbinary
Registered serializer handlers => php_serialize php php_binary igbinary

wooopppiiiii
Yes.. that saved the situation completly.. thank you so much !!
