PHP Startup: Unable to load dynamic library 'redis.so' #213

beejaz · 2020-10-16T09:33:12Z

Expected Behavior

Enable redis support in PHP in thecodingmachine/php:7.4-v3-slim-fpm

Current Behavior

Container crashing on start or giving constant errors on load.

Possible Solution

As discussed in #200 maybe add delay or other order of loading

Steps to Reproduce (for bugs)

php/Dockerfile:

ARG PHP_EXTENSIONS="apcu mysqli pdo_mysql ldap redis intl imap"
ARG NODE_VERSION=10
FROM thecodingmachine/php:7.4-v3-slim-fpm as php7.4-base-node10

docker-compose.yml:

  php:
    container_name: 'php'
    build:
      context: ./php
    environment:
      PHP_EXTENSION_REDIS: 1
      PHP_EXTENSION_GETTEXT: 1
      PHP_EXTENSION_PDO: 1
      PHP_EXTENSION_PDO_MYSQL: 1
      PHP_EXTENSION_LDAP: 1
      PHP_EXTENSION_INTL: 1

docker-compose up

When disabling PHP_EXTENSION_REDIS: 0 it starts:

php      | [16-Oct-2020 09:34:05] NOTICE: fpm is running, pid 1845
php      | [16-Oct-2020 09:34:05] NOTICE: ready to handle connections
php      | [16-Oct-2020 09:34:05] NOTICE: systemd monitor interval set to 10000ms

On another container that has redis in ARG PHP_EXTENSIONS i get this error everytime i do something in console with php:

PHP Warning:  PHP Startup: Unable to load dynamic library 'redis.so' (tried: /usr/lib/php/20190902/redis.so (/usr/lib/php/20190902/redis.so: undefined symbol: igbinary_serialize), /usr/lib/php/20190902/redis.so.so (/usr/lib/php/20190902/redis.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

Context

Im trying to enable redis support in the image. If i turn off redis PHP_EXTENSION_REDIS: 0 i wont get any errors, but if I turn it on, it will either crash on start or if it runs, php will give error when trying to use redis for connection.
Similar problem discussed here #200 but i didn't find any solution.

Do you use docker-composer up followed by exec or do you use docker-compose run? The latter is safe, the former can lead to a race condition with errors like this.

beejaz · 2020-11-06T08:27:29Z

Hi @mbrodala thanks for your response, I use docker-compose up -d with this

version: '3.1'

services:
  php:
    build:
      context: ./php
      args:
        - PHP_ROOT_DIR=/usr/local/etc
    environment:
      TEMPLATE_PHP_INI: development
      PHP_EXTENSION_GETTEXT: 1
      PHP_EXTENSION_PDO: 1
      PHP_EXTENSION_PDO_MYSQL: 1
      PHP_EXTENSION_LDAP: 1
      PHP_EXTENSION_INTL: 1
      PHP_EXTENSION_REDIS: 1
    volumes:
      - ./project:/var/www/html
      - ./logs/php:/usr/local/etc/logs
      - ./logs/php:/usr/local/var/log

If i run "docker-compose run php -d" it will give me error also:

undefined symbol: igbinary_serialize

This sounds like a loading issue since redis.so looks like being built with igbinary support but that extension is not loaded or in a wrong version.

@moufmouf I can see the install.sh of redis which does not have DEPENDENCIES like the memcached version which it is obviously based on:

https://github.com/thecodingmachine/docker-images-php/blob/c4bce49e16b69a4121e2da54fb95a9e467902768/extensions/core/redis/install.sh

Could this be the reason?

beejaz · 2020-11-08T19:54:36Z

I tried adding memcached to my Dockerfile and PHP_EXTENSION_MEMCACHED: 1 to docker-compose.yml which ended up showing more errors after a fresh docker-compose build php

Ive tried to find information about this issue, some say its a issue with Ubuntu 18.04 and php/redis. Some suggest to change order of loading extensions;
20-igbinary.ini
30-redis.ini

Some other suggest installing the stuff you mentioned above @mbrodala
sudo apt-get install php-igbinary
sudo apt-get install php-msgpack

moufmouf · 2020-11-27T11:29:26Z

Sorry for the delay.
@beejaz I'm working on a v4 of the Docker image based on Ubuntu 20.04. It does not have this issue. I'll keep you posted.

@beejaz I'm sorry but it is stil not working.

I would love to use the phpredis extention in my laravel project running laravel horizon.

moufmouf · 2020-12-14T08:51:12Z

Ok, I'll check that!

robjuz · 2020-12-16T12:40:12Z

@moufmouf
Maybe this will help.

I tried to build my own image based on Ubuntu 20.04 and come to the same problem. After some googling I found out that there is a problem with the extension loading order.

This is working

FROM ubuntu:20.04

RUN apt-get update -y
RUN apt-get install -y php7.4-redis


RUN echo 'priority=20' >> /etc/php/7.4/mods-available/igbinary.ini
RUN echo 'priority=30' >> /etc/php/7.4/mods-available/redis.ini

This image is using the ondrej/php repository. I don't know why, but it is not working with its version.

So cloned this repo, emoved the ondrej/php, installed the extension, ran phpdismod igbinary redis changed the priority, enabled the extensions.

Working!

robjuz · 2020-12-22T11:54:28Z

@moufmouf any update on this? Maybe the issue should be reopened?

beejaz · 2021-01-08T09:40:18Z

I just tried the latest v4 fpm slim image, got the same error also fyi @moufmouf :)

robjuz · 2021-01-28T05:00:55Z

@moufmouf Can you give us a quick note what do you think about this issue? I really love you images and this is a serious problem.

beejaz · 2021-03-09T18:46:24Z

@moufmouf Hi, sorry to disturb you, any updates here?

bustersky · 2021-04-07T22:39:47Z

I came across the same issue and got to the solution...
If you use a slim image you have to enable igbinary alongside with the redis one, as they are enabled by default in fat images only: https://github.com/thecodingmachine/docker-images-php#fat-image

So in case of @beejaz that would be:

version: '3.1'

services:
php:
build:
context: ./php
args:
- PHP_ROOT_DIR=/usr/local/etc
environment:
TEMPLATE_PHP_INI: development
PHP_EXTENSION_GETTEXT: 1
PHP_EXTENSION_PDO: 1
PHP_EXTENSION_PDO_MYSQL: 1
PHP_EXTENSION_LDAP: 1
PHP_EXTENSION_INTL: 1
PHP_EXTENSION_IGBINARY: 1
PHP_EXTENSION_REDIS: 1
volumes:
- ./project:/var/www/html
- ./logs/php:/usr/local/etc/logs
- ./logs/php:/usr/local/var/log

And in case of @robjuz

ARG PHP_EXTENSIONS="bcmath pdo_sqlite igbinary redis"
FROM thecodingmachine/php:8.0-v4-slim-apache

ENV APACHE_DOCUMENT_ROOT=public/
APACHE_RUN_USER=www-data
APACHE_RUN_GROUP=www-data
...

I hope this will help you.
