一、移除旧版php
yum remove php-mysql-5.4 php php-fpm php-common -y
二、配置扩展源
yum localinstall -y http://mirror.webtatic.com/yum/el7/webtatic-release.rpm
三、安装php7.1版
yum -y install php71w php71w-cli php71w-common php71w-devel
php71w-embedded php71w-gd php71w-mcrypt php71w-mbstring php71w-pdo php71w-xml php71w-fpm
php71w-mysqlnd php71w-opcache php71w-pecl-memcached php71w-pecl-redis php71w-pecl-mongodb
https://www.php.net/distributions/php-7.3.5.tar.gz
四、统一系统权限，修改php-fpm运行的用户和组身份
sed -i '/^user/c user = www' /etc/php-fpm.d/www.conf
sed -i '/^group/c group = www' /etc/php-fpm.d/www.conf
五、创建用户（www）
useradd www
六、启动php-fpm管理进程，并加入开机自启
systemctl start php-fpm
systemctl enable php-fpm
