Install PHP7

1 添加源

yum -y install epel-release

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

2 安装php7

添加源后，更新一下，yum updateinfo，然后yum search php7 看下源里PHP7存在哪些小版本:

...mod_php71w.x86_64 : PHP module for the Apache HTTP Serverphp71w-bcmath.x86_64 : A module for PHP applications for using the bcmathphp71w-cli.x86_64 : Command-line interface for PHPphp71w-common.x86_64 : Common files for PHPphp71w-dba.x86_64 : A database abstraction layer module for PHP applicationsphp71w-devel.x86_64 : Files needed for building PHP extensionsphp71w-embedded.x86_64 : PHP library for embedding in applicationsphp71w-enchant.x86_64 : Enchant spelling extension for PHP applications...

看样子已经到PHP7.1了，那就体验下最新的特性，使用命令yum install mod_php71w php71w-cli php71w-devel php71w-mysql安装，如果没有MySQL需求，可以去掉php71w-mydql. 安装成功后，php -v查看版本信息:

Install Nginx

安装nginx也比较简单，根据就可以完成。 我安装的是稳定版。 vi /etc/yum.repos.d/nginx.repo

[nginx]name=nginx repobaseurl=http://nginx.org/packages/centos/7/$basearch/gpgcheck=0enabled=1

然后yum search nginx查看版本，选择需要的版本，我选了默认的版本，并安装了扩展：yum install nginx nginx-all-modules. 安装完毕，nginx -V查看Nginx的版本和路径参数及扩展支持：
