/etc/php.ini、PHP-FPM配置文件/etc/php-fpm.d/等。sudo yum install epel-releasesudo yum install https://rpms.remirepo.net/enterprise/remi-release-7.rpm（CentOS 7）或sudo dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm（CentOS 8）sudo yum-config-manager --enable remi-php74（將74替換為所需版本號）sudo yum update php*sudo systemctl restart httpdsudo systemctl restart nginx和sudo systemctl restart php-fpmphp -v，查看輸出確認PHP版本已更新。
