Step 1: install php-gmp
[root@CentOS-75-64-minimal /]# yum install php-gmp Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirror.checkdomain.de * epel: mirror.wiuwiu.de * extras: mirror.checkdomain.de * remi-php71: mirror.23media.de * remi-safe: mirror.23media.de * updates: mirror.checkdomain.de Resolving Dependencies --> Running transaction check ---> Package php-gmp.x86_64 0:7.1.20-1.el7.remi will be installed --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: php-gmp x86_64 7.1.20-1.el7.remi remi-php71 67 k Transaction Summary ================================================================================ Install 1 Package Total download size: 67 k Installed size: 134 k Is this ok [y/d/N]: y Downloading packages: php-gmp-7.1.20-1.el7.remi.x86_64.rpm | 67 kB 00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : php-gmp-7.1.20-1.el7.remi.x86_64 1/1 Verifying : php-gmp-7.1.20-1.el7.remi.x86_64 1/1 Installed: php-gmp.x86_64 0:7.1.20-1.el7.remi Complete!
Now you can see file gmp.so and 20-gmp.ini
[root@CentOS-75-64-minimal /]# find -name gmp.so ./usr/lib64/php-zts/modules/gmp.so ./usr/lib64/php/modules/gmp.so
[root@CentOS-75-64-minimal /]# find -name *gmp.ini ./etc/php.d/20-gmp.ini ./etc/php-zts.d/20-gmp.ini
Step 2 (optinal if not exists file /etc/php.d/20-gmp.ini): restart PHP-FPM
service php-fpm restart
now you can see gmp in phpinfo:
