Vm: Redis spams the log with Unable to load dynamic library 'redis.so'

[enoch85]

Fresh installed latest Nextcloud VM 13 has an error in system logs:

PHP Startup: Unable to load dynamic library 'redis.so' (tried: /usr/lib/php/20170718/redis.so (/usr/lib/php/20170718/redis.so: undefined symbol: igbinary_serialize), /usr/lib/php/20170718/redis.so.so (/usr/lib/php/20170718/redis.so.so: cannot open shared object file: No such file or directory)) at Unknown#0

This is most likely a dependency issue. Waiting for Ubuntu to update their packages.

Found this: https://bugs.launchpad.net/ubuntu/+source/php-redis/+bug/1762935

Seems like a bug in Ubuntu 18.04.

ok i might found a proper solution to this.

i have done this under Ubuntu 18.04 LTS:

apt-get install php7.2-dev

----------------------------------------------------------------------
Libraries have been installed in:
   /tmp/pear/temp/pear-build-rootDDB4jL/redis-4.0.2/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

You should add "extension=redis.so" to php.ini
Segmentation fault (core dumped)

why segmentation faulted here i don't know, maybe it ended cleanly without errors and the new extension was added to /usr/lib/php/20170718/.

Attention: This above adds multiple times in /etc/php/7.2/apache2/php.ini the extension to load ad the end of the file. Apache will let you know this like this:

[Thu May 24 08:25:58.749846 2018] [http2:warn] [pid 7718] AH10034: The mpm module (prefork.c) is not supported by mod_http2. The mpm determines how things are processed in your server. HTTP/2 has more demands in this regard and the currently selected mpm will just not do. This is an advisory warning. Your server will continue to work, but the HTTP/2 protocol will be inactive.

PHP Warning:  Module 'redis' already loaded in Unknown on line 0
PHP Warning:  Module 'redis' already loaded in Unknown on line 0
PHP Warning:  Module 'redis' already loaded in Unknown on line 0

so just remove the multiple entries due its loaded already in the ini files through:

/etc/php/7.2/cli/conf.d/
and
/etc/php/7.2/apache2/conf.d/

This solved my issues with the missing redis.so library thing and all errors went off.

We used PECL before in the old scripts and yes, we didn't have the log entry but users change the default value from no to yes when updating Redis, so I decided to use this solution instead of using PECL.

So which is best:

1. A log entry that spams the log but doesn't do any harm
2. The risk of users changing the default value and break Redis

I think option 1 is best.

So it should rather used with build option “no” for redis support? I don’t understand - can you be more specific why you discarded redis built in on php module ? Think this are 2 different things - unless Ubuntu php package is somehow broken and my intention was to get latest redis option to php - this was archived by PECL :-)

[enoch85]

When you build with PECL you can choose to enable support for memcache and some other stuff (I don't remember now) and most users think "hey, that sounds good, let's enable it" and then change the default [no] to [yes]. Problem is, that will break Redis as no memcache is installed.

I fixed that by always answering "no" with the yes command as you can sse in the code I linked, but I'd rather work with built in dependencies than using something like PECL, which is 3:rd-party.

[enoch85]

@fgrosswig Any update here?

[fgrosswig]

i rather would close this issue. I would prefer the way to have an "un-noisy" log handling so maybe this is only on Ubuntu 18 LTS. There is a problem with redis anyway and my solution above fix it sufficient. :-)

[enoch85]

OK, let's close this and hope that the maintainer of Redis in Ubuntu fixes the issue in comiong releases. :)

[pcreadycl]

The error still in NC 15... Anyone?

[enoch85]

@pcreadycl The VM uses the PECL installation method since some versions back. Just run the built in update script to fix it.

sudo bash /var/scripts/update.sh

[wmh]

try to change the priority of loading extension:

20-igbinary.ini
30-redis.ini

[enoch85]

@wmh Is this for the current PECL implementation or is it for the old one?

Afaik there are no issues with the new implementation.
