nginx环境准备
php环境准备：
##使用第三方扩展源安装php7.1*
#不要安装如下rpm会导致失败
# rpm -Uvh https://d1.fedoraproject.org/pub/epe1/epe1-release-latest-7.noarch.rpm
# rpm -Uvh https://mirror.webtatic.com/yum/e17/webtatic-release.rpm
[root@nginx ~]# yum remove php-mysq1-5.4 php php-fpm php-common
#配置php yum源
#安装完成后记得把这个php源注释掉
[root@nginx ~]# cat /etc/yum.repos.d/php.repo
[webtatic-php]
name = php Repository
baseur1= http://us-east.repo.webtatic.com/yum/e17/x86_64/
gpgcheck =0
或者
yum 安装php源
yum install epel-release
安装REMI源
yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
安装yum源管理工具
yum install yum-utils
安装php7.3
yum install -y php73-php-fpm php73-php-cli php73-php-bcmath php73-php-gd php73-php-json php73-php-mbstring php73-php-mcrypt php73-php-mysqlnd php73-php-opcache php73-php-pdo php73-php-pecl-crypto php73-php-pecl-mcrypt php73-php-pecl-geoip php73-php-recode php73-php-snmp php73-php-soap php73-php-xmll
systemctl enable php73-php-fpm
systemctl start php73-php-fpm
查找php.ini位置
[root@xxx etc]# find /etc/opt/remi/php73 -name php.ini
/etc/opt/remi/php73/php.ini
编辑/etc/opt/remi/php73/php.ini替换换 ;cgi.fix_pathinfo=1 为 cgi.fix_pathinfo=0 快捷命令：
sed -i 's/;cgi.fix_pathinfo=1/cgi.fix_pathinfo=0/' /etc/opt/remi/php73/php.ini这里是将参数cgi.fix_pathinfo置为0，作用是：
php.ini中的配置参数cgi.fix_pathinfo，它是用来对设置cgi模式下为php是否提供绝对路径信息或PATH_INFO信息。没有这个参数之前PHP设置绝对路径PATH_TRANSLATED的值为SCRIPT_FILENAME，没有PATH_INFO值。设置cgi.fix_pathinfo=1后，cgi设置完整的路径信息PATH_TRANSLATED的值为SCRIPT_FILENAME，并且设置PATH_INFO信息；如果设为cgi.fix_pathinfo=0则只设置绝对路径PATH_TRANSLATED的值为SCRIPT_FILENAME。cgi.fix_pathinfo的默认值是1。
nginx默认是不会设置PATH_INFO环境变量的的值，需要通过正则匹配设置SCRIPT_FILENAME，但这样会带来安全隐患，需要把cgi.fix_pathinfo=0设置为0。但是一旦关闭这个这场，PHP就获取不到PATH_INFO信息，那些依赖PATH_INFO进行URL美化的程序就失效了。
重启php73-php-fpm
systemctl restart php73-php-fpm
更多操作：
systemctl restart php73-php-fpm#重启
systemctl start php73-php-fpm#启动
systemctl stop php73-php-fpm#关闭
systemctl status php73-php-fpm #检查状态
查看PHP版本信息：
