Unable to use homebrew to install phpredis. #1341

Unable to use homebrew to install phpredis. #1341

Comments

Homebrew-php is deprecated/deleted/dead as a dodo.
Homebrew-core is now the thing.
brew install php70-redis (or any version) is no longer present.

Whilst it isn’t directly phpredis’s issue what some third party package manager has done, I’m hoping someone here knows the right magic to install this extension, ideally via homebrew (but not necessary if an easier option is available).

The text was updated successfully, but these errors were encountered:

I realised that once I realised phpredis and pecl/redis are the same. Any reason why the names aren’t consistent?

pecl install redis results in this:

Build process completed successfully Installing '/usr/local/Cellar/php/7.2.7/pecl/20170718/redis.so' Warning: mkdir(): File exists in System.php on line 294 Warning: mkdir(): File exists in /usr/local/Cellar/php/7.2.7/share/php/pear/System.php on line 294 ERROR: failed to mkdir /usr/local/Cellar/php/7.2.7/pecl/20170718 

Solution

Because /usr/local/Cellar/php/7.2.7/pecl is not a directory. It’s a symlink to /usr/local/lib/php/pecl

The solution to that is that the pecl that’s being used is in /usr/local/Cellar/php/7.2.7/bin/pecl , and not the 7.2.7/pecl file, so that symlink can be removed, and a directory created.

For those who bump into this problem.

Double check which pecl and what that file is pointing to, etc.

One issue I ran into is that pecl install redis dumped extension=»redis.so» at the top of my php.ini`. This was invalid, and gave me an error like this:

Warning: PHP Startup: Unable to load dynamic library 'redis.so' (tried: /usr/local/lib/php/pecl/20170718/redis.so (dlopen(/usr/local/lib/php/pecl/20170718/redis.so, 9): image not found), /usr/local/lib/php/pecl/20170718/redis.so.so (dlopen(/usr/local/lib/php/pecl/20170718/redis.so.so, 9): image not found)) in Unknown on line 0 

I removed the extension=»redis.so» line and instead created /usr/local/etc/php/7.2/conf.d/ext-redis.ini with:

extension="/usr/local/Cellar/php/7.2.9_2/pecl/20170718/redis.so" 

$ find your php; for me it was /usr/local/etc/php/7.1/conf.d/
$ navigate there and:
cat >> ext-redis.ini extension=»/usr/local/Cellar/php@7.1/7.1.25/pecl/20160303/redis.so»
AyeCaramba
$ brew services restart php@7.1

version in the above
extension=»/usr/local/Cellar/php@7.1/7.1.25/pecl/20160303/redis.so»
may differ to make sure to double check that path.

I got the same issue and until I saw this comment and it works.

Default location is totally wrong lol

I’m seeing this behaviour on

$ pecl install igbinary // 3.2.7
$ pecl install zstd
$ pecl install redis

Steps to reproduce, backtrace or example script

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

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

Comments

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)

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 

 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 

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 php | /usr/local/bin/docker-entrypoint-as-root.sh: line 129: supercronic: command not found 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 php | bash: line 2: syntax error near unexpected token `(' php | bash: line 2: `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' 

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.
