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 安装完成后最好重启一下计算机，不然有可能无法启动php 设置开机启动、运行服务：
systemctl enable php73-php-fpm systemctl start php73-php-fpm 1 设置 PHP 查找安装包：
[root@xxx etc]# rpm -qa | grep 'php' php73-php-cli-7.3.6-1.el7.remi.x86_64 php73-php-mbstring-7.3.6-1.el7.remi.x86_64 php73-php-pecl-mcrypt-1.0.2-1.el7.remi.x86_64 php73-runtime-2.0-1.el7.remi.x86_64 php73-php-pdo-7.3.6-1.el7.remi.x86_64 php73-php-bcmath-7.3.6-1.el7.remi.x86_64 php73-php-fpm-7.3.6-1.el7.remi.x86_64 php73-php-mysqlnd-7.3.6-1.el7.remi.x86_64 php73-php-snmp-7.3.6-1.el7.remi.x86_64 php73-php-gd-7.3.6-1.el7.remi.x86_64 php73-php-json-7.3.6-1.el7.remi.x86_64 php73-php-soap-7.3.6-1.el7.remi.x86_64 php73-php-recode-7.3.6-1.el7.remi.x86_64 php73-php-pecl-crypto-0.3.1-5.el7.remi.x86_64 php73-php-common-7.3.6-1.el7.remi.x86_64 php73-php-opcache-7.3.6-1.el7.remi.x86_64 php73-php-pecl-geoip-1.1.1-6.el7.remi.x86_64 找到：php73-php-fpm-7.3.6-1.el7.remi.x86_64安装位置
[root@xxx etc]# rpm -ql php73-php-fpm-7.3.6-1.el7.remi.x86_64 /etc/logrotate.d/php73-php-fpm /etc/opt/remi/php73/php-fpm.conf /etc/opt/remi/php73/php-fpm.d /etc/opt/remi/php73/php-fpm.d/www.conf /etc/opt/remi/php73/sysconfig/php-fpm /etc/systemd/system/php73-php-fpm.service.d /opt/remi/php73/root/usr/sbin/php-fpm /opt/remi/php73/root/usr/share/doc/php73-php-fpm-7.3.6 /opt/remi/php73/root/usr/share/doc/php73-php-fpm-7.3.6/php-fpm.conf.default /opt/remi/php73/root/usr/share/doc/php73-php-fpm-7.3.6/www.conf.default /opt/remi/php73/root/usr/share/fpm /opt/remi/php73/root/usr/share/fpm/status.html /opt/remi/php73/root/usr/share/licenses/php73-php-fpm-7.3.6 /opt/remi/php73/root/usr/share/licenses/php73-php-fpm-7.3.6/fpm_LICENSE /opt/remi/php73/root/usr/share/man/man8/php-fpm.8.gz /usr/lib/systemd/system/php73-php-fpm.service /var/opt/remi/php73/lib/php/opcache /var/opt/remi/php73/lib/php/session /var/opt/remi/php73/lib/php/wsdlcache /var/opt/remi/php73/log/php-fpm /var/opt/remi/php73/run/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 1 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 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 1 2 3 查看 PHP 验证一下是否安装成功：
