我应该如何在CentOS 7上安装php 7.x？
此外，如果我忽略它并遵循以下命令，即使我已删除php5.x，它也会继续安装php 5.x：

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
$ sudo yum install --skip-broken php php-common php-opcache php-mcrypt php-cli php-gd php-curl php-mysqlnd

首先，您不需要 在Centos上的Remi存储库来获取PHP 7，目前（就像今天一样），您确实需要PHP 7.3。
但是，如果您要安装 PHP 7
您可以在 epel repository 上在Centos上进行 EDIT 7.2（我建议立即用于生产）：
首先检查您是否安装了正确的存储库：
$ yum repolist | grep -e ius -e remi
如果您还没有这些存储库之一，则需要安装它。
在那之后，仅需删除旧的PHP并安装PHP 7（IUS 7.2或remi 7.3）即可。
$ yum remove php* -y
$ yum install php72u
根据Remi的评论，php72u实际上来自IUS，我没有注意到！
要从remi存储库中获取PHP 7.3，可以运行yum update或：
$ yum install php php-cli php-fpm php-mysqlnd php-zip php-devel php-gd php-mcrypt php-mbstring php-curl php-xml php-pear php-bcmath php-json

答案 2 :(得分：-1)
RHEL 7 Server上PHP 7.x的安装步骤
1）启用EPEL，RHEL 7 Server可选存储库并安装remirepo rpm
Login to your RHEL 7 Server and run the beneath commands one after the another to enable EPEL repository, install remirepo and enable RHEL 7 Server optional repository
[root@user~]# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[root@user ~]# wget http://rpms.remirepo.net/enterprise/remi-release-7.rpm
[root@user ~]# rpm -Uvh remi-release-7.rpm epel-release-latest-7.noarch.rpm
[root@user ~]# subscription-manager repos --enable=rhel-7-server-optional-rpms
2）配置PHP 7.x存储库
[root@user ~]# yum install yum-utils
[root@user ~]# yum-config-manager --enable remi-php72
3）安装PHP 7.2及其依赖项
[root@user ~]# yum install php php-common php-opcache php-mcrypt php-cli php-gd php-curl php-mysql -y
4）验证PHP版本
[root@user ~]# php -v
请参考下面的链接以获取详细信息，它为您提供了逐步操作的步骤：
