yum安装nginx、php

1：nginx
yum install nginx 直接安装（出现问题直接百度可解决）
2：php7.3
yum install epel-release
yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum install yum-utils
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

安装php扩展
yum install php73-php curl

命令切换

如果你安装了好几个PHp版本
查询安装的
yum list installed php
yum list installed php|geep 过滤

直接复制多余的
yum remove xxx 卸载

whereis php版本命令 user/bin 一般在这里
直接cp php777 php
就可以把php777的命令改为默认的php
