PHPRedis with IGBinary is a powerful tool to increase your redis connections from PHP. Instead of using libraries like predis, you can install PHPRedis which is a C library. This dramatically improves the performance when using Redis with PHP. We’ll show you how to do the PHPRedis installation on DirectAdmin!
This tutorial is written for RHEL/CentOS/RockyLinux/AlmaLinux and other distros based on RHEL.
Install Redis with DNF
If you haven’t already installed Redis, you can do this easily with DNF:
dnf install redis systemctl enable --now redis.service systemctl start redis.service chown:chown redis:redis /etc/redis.conf
The next step is to install the PHPRedis C library, with IGBinary as serialiser.
Install IGBinary
Download the latest release (tar.gz) from: https://github.com/igbinary/igbinary/releases
- Download latest release for example in /root/php_ext/igbinary
tar -xzf *latest_release.tar.gz* cd *latest_release.tar.gz* /usr/local/php80/bin/phpize80 ./configure CFLAGS="-O2 -g" --enable-igbinary make make test make install
Install PHPRedis
https://github.com/phpredis/phpredis/releases
- Download latest release for example in /root/php_ext/phpredis
tar -xzf *latest_release.tar.gz* cd *latest_release*.tar.gz /usr/local/php80/bin/phpize80 ./configure --enable-redis-igbinary --with-php-config=/usr/local/php80/bin/php-config80 make make install
Add extensions to PHP config
cd /usr/local/php80/lib/php.conf.d touch 20-custom.ini
If you use another PHP version, change it accordingly.
In this file, add:
extension=igbinary.so extension=redis.so
And finally reload/restart php-fpm. Verify with:
php --ri redis or php -m
If you see redis and igbinary in the list you have successfully installed the PHPRedis C extension with IGbinary as serialiser to your PHP installation!
