At first I thought it was because openssl and openssl-devel were not installed, but I found this error after installation.

Solution: modify the configure file to add

This is an error when installing the mysqlnd extension

export PHP_OPENSSL_DIR = yes
  ./configure --with-php-config=/home/php/bin/php-config --enable-mysqlnd
