I resolved with the Alexander's answer: yum install php-gd yum install php-mysql yum install php-snnmp however I have i386 and the output of rpm -qa --qf '%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}\n' php\* is: php-mysql-5.0.4-10.4.i386 php-5.0.4-10.4.i386 php-gd-5.0.4-10.4.i386 php-snmp-5.0.4-10.4.i386 php-pear-5.0.4-10.4.i386 Now is all OK!!
