问题
I installed nginx, php, php-fpm, php-pecl-redis by yum.
All of them work but the last one.
When I run /usr/sbin/php-fpm
, I got this:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/redis.so' - /usr/lib/php/modules/redis.so: undefined symbol: igbinary_unserialize in Unknown on line 0
I don't know what "igbnary_unserialize" means and how to fix it.
I checked the redis.so file under right path.
I add extension=redis.so
to "php.ini"
php version: 5.3.3
phpredis version: 2.2.7

I had the same issue. I'm on Ubuntu 16.04 LTS. Running sudo apt-get install php-igbinary
resolved the issue for me. I have other issues, but that's what solved this one.
回答2:
Probably an issue with igbinary, is this installed? (try for example: cat /etc/php.d/igbinary.ini
).
Here you can find and install igbinary

You should remove php-redis from packages:
apt purge php-redis
, and install it via pecl install redis
You should add "extension=redis.so" to php.ini
and remove redis from config.d in your php directory:
rm /etc/php/7.2/fpm/conf.d/@20-redis.ini
and
rm /etc/php/7.2/cli/conf.d/@20-redis.ini
restart php fpm and you will see that problem solved

just resolve the same problem:
php-pecl-redis installed by yum will cause this problem. so you need to install the php-redis manually. wget the package and phpize - configure - make ....
