以前安装php及php-fpm是个痛苦的事，编译完后得几个小时，现在推荐yum来安装，比较方便。
系统centos 6
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
rpm -Uvh http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -Uvh http://repo.webtatic.com/yum/el6/latest.rpm
安装mysql
yum --enablerepo=remi install mysql mysql-server
安装php php-fpm nginx
yum install nginx php54w php54w-cli php54w-common php54w-devel php54w-fpm php54w-gd php54w-imap php54w-mbstring php54w-mcrypt php54w-mysql php54w-pdo php54w-process php54w-xml php54w-xmlrpc -y
如果安装失败，建议您先卸载以前的php再进行安装，使用yum remove php php-*
service php-fpm start
service nginx start
chkconfig nginx on
chkconfig php-fpm on
配置文件在 /etc/php.ini
配置文件在 /etc/nginx/nginx.conf
