先下载php7
wget http://cn2.php.net/get/php-7.0.2.tar.gz/from/this/mirror
解压下载下来的文件
tar -zxvf php-7.1.0.tar.gz
卸载之前php
yum remove php rpm -qa|grep php //php相关列表 rpm -e php-cli-5.4.16-42.el7.x86_64 //逐一删除

出现错误，解决方案
1）freetype.h not fount => yum install freetype-devel
2）onfigure: error: Please reinstall the libcurl distribution - easy.h should be in /include/curl/ => yum install curl curl-devel
3）cannot find openssl\'s<evp.h> => yum install openssl openssl-devel
4）configure error xml2-config not found. please check your libxml2 installation => yum install libxml2 libxml2-devel
5）png.h not found. => yum install libpng-devel

配置相应文件
cp php.ini-development /usr/local/php/php.ini cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf cp sapi/fpm/php-fpm /usr/local/bin
设置php.ini
vi /usr/local/php/php.ini
打开php配置文件找到cgi.fix_pathinfo配置项，这一项默认被注释并且值为1，根据官方文档的说明，这里为了当文件不存在时，阻止Nginx将请求发送到后端的PHP-FPM模块，从而避免恶意脚本注入的攻击，所以此项应该去掉注释并设置为0
修改php-fpm
然后网上一些教程说让修改php-fpm.conf添加以上创建的用户和组，
find / -name php-fpm.conf
vim ....php-fpm.conf
修改
默认情况下etc/php-fpm.d/下有一个名为www.conf.defalut的配置用户的文件，执行下面命令复制一个新文件并且打开：
cp www.conf.default www.conf vi www.conf
默认user和group的设置为nobody，将其改为合适的。
启动php-fpm
/usr/local/bin/php-fpm
php-fpm服务默认使用9000端口，使用 netstat -tln | grep 9000 可以查看端口使用情况：

更新静项原
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
Error
epel-release >= 7 被 webtatic-release-7-3.noarch 需要
解决
yum install epel-release
yum install
yum install php70w php70w-bcmath php70w-cli php70w-common php70w-dba php70w-devel php70w-embedded php70w-enchant php70w-fpm php70w-gd php70w-imap php70w-interbase php70w-intl php70w-ldap php70w-mbstring php70w-mcrypt php70w-mssql php70w-mysql php70w-odbc php70w-opcache php70w-pdo php70w-pecl-memcache php70w-pecl-xdebug php70w-pgsql php70w-process php70w-pspell php70w-recode php70w-snmp php70w-soap php70w-tidy php70w-xml php70w-xmlrpc
nginx支持php，安装php时一定需要带php-fpm
先启动php-fpm
/usr/sbin/php-fpm
修改nginx.conf
location ~ \.php$ { fastcgi_pass 127.0.0.1:9000;#php-fpm的默认端口是9000 fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; }
重启nginx
systemctl restart nginx
写个phpinfo浏览器访问就可以：
或者：
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm //升级本地镜像源，可能会失败，多试几次
yum install
