1、Nginx 安装
rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm \官网rpm直接安装 注意后面改成当前最新的版本
（如果是CentOS 6+版本 需要执行 yum install nginx)
systemctl start nginx.service
2、PHP安装（2018年更新，由于默认安装是PHP5的老环境，所以需要更新源，才能YUM安装新版的php7.0+）
CentOS/RHEL 7.x:
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm如果是centos6，那么执行以下代码：
CentOS/RHEL 6.x:
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm然后就可以直接yum安装php7.0了，可以安装的拓展如下：
yum install php70w-common php70w-fpm php70w-opcache php70w-gd php70w-mysqlnd php70w-mbstring php70w-pecl-redis php70w-pecl-memcached php70w-devel
yum install php70w php70w-fpm php70w-devel
systemctl start php-fpm
以上。
ps:还有更牛的！一般都要安装memcached，gd,mysql
