Hello, for drupal 7 installation at CentOS 5.5 (I have 32 bit and 64 bit machines) I have to upgrade PHP to 5.3. I've followed the CentOS wiki: 1) Created this file - grep -v ^# /etc/yum.repos.d/CentOS-Testing.repo [c5-testing] name=CentOS-5 Testing baseurl=http://dev.centos.org/centos/$releasever/testing/$basearch/ enabled=1 gpgcheck=1 gpgkey=http://dev.centos.org/centos/RPM-GPG-KEY-CentOS-testing includepkgs=php* 2) Uninstalled the old PHP - rpm -qa|grep php| xargs sudo yum -y erase 3) Installed new php53: # rpm -qa |grep php php53-pgsql-5.3.3-1.el5 php53-gd-5.3.3-1.el5 php53-pdo-5.3.3-1.el5 php53-xml-5.3.3-1.el5 php53-cli-5.3.3-1.el5 php53-common-5.3.3-1.el5 php53-mbstring-5.3.3-1.el5 4) Verified php works: php -v PHP 5.3.3 (cli) (built: Jan 20 2011 23:02:42) Copyright (c) 1997-2010 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies Unfortunately I need Fileinfo module too, for my script. I do not see "pecl" though and also "yum install php-pecl-Fileinfo" fails with "wrong version" error. Any help please on how to install Fileinfo? Thank you Alex
