服务器配置PHP环境+Oracle支持
安装Nginx源：
rpm -ivh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
安装EPEL源:
(64位系统) rpm -ivh http://download.fedora.redhat.com/pub/epel/6/x86_64/epel-release-6-5.noarch.rpm
(32位系统) rpm -ivh http://download.fedora.redhat.com/pub/epel/6/i386/epel-release-6-5.noarch.rpm
安装REMI源:
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
开启REMI,编辑源设置
vim /etc/yum.repos.d/remi.repo
修改 enable=1
安装基础包：
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers libmcrypt libmcrypt-devel pcre-devel
安装PHP+Mysql：
yum -y install nginx mysql-server php-fpm php-cli php-pdo php-mysql php-mcrypt php-mbstring php-gd php-tidy php-xml php-xmlrpc php-pear php-pecl-memcache php-eaccelerator
修改/etc/php-fpm.conf 的用户和组为nginx（apache-->nginx）
修改/var/lib/php/session(使php能保存session)，web用户组为nginx
chown -R nginx:nginx /var/lib/php/session(不存在则需要创建)
chown -R nginx:nginx /home/htdocs/(web目录)
chmod -R 775 /home/htdocs/ (同组可修改权限,方便配置ftp,ftp应该加入到nginx组,如果需要更高的安全设置,则不应当将只读的目录赋予nginx,php组可写权限)
设置自启动
chkconfig nginx on
chkconfig php-fpm on
chkconfig mysqld on
安装oci8支持
