1. Download
wget http://cn2.php.net/distributions/php-7.0.30.tar.gz 解压 tar -zxvf php-7.0.30.tar.gz
2. Download and install dependencies
yum -y install gcc openssl openssl-devel curl curl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel pcre pcre-devel libxslt libxslt-devel bzip2 bzip2-devel
3. Compile and install php
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-pdo-mysql --with-mysqli --with-gd --with-zlib --with-mcrypt --enable-fpm make && make install 安装完成后，别忘记 make test 有如下报错 configure: error: mcrypt.h not found. Please reinstall libmcrypt. 解决 yum install -y epel-release yum install -y libmcrypt-devel 重新编译
4. Configure PHP Related files
1）配置php.ini，这是php的配置文件： cp /etc/we/php-7.1.11/php.ini-development /usr/local/php/lib/php.ini 2）配置php-fpm.conf，这是php-fpm配置文件： cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf 3）配置www.conf，配置用户的文件： cp etc/php-fpm.d/www.conf.default etc/php-fpm.d/www.conf 4）将php-fpm启动文件复制到init.d文件夹中一份方便启动php： cp /usr/local/php/sbin/php-fpm /etc/init.d/php-fpm
5. Start php and confirm whether the installation is successful
执行命令/etc/init.d/php-fpm即可 查看是否启动：ps -ef |grep php
