我正在使用 CentOS 7、Nginx 1.12.2 。根据文章https://www.svnlabs.com/blogs/install-apache-mysql-php-5-6-on-centos-7/，我尝试
rpm -Uvh http://vault.centos.org/7.0.1406/extras/x86_64/Packages/epel-release-7-5.noarch.rpm
结果

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
[root@VMHostDefault ~]#
然后检查PHP版本
[root@VMHostDefault ~]# php -v
PHP 7.3.5 (cli) (built: Apr 30 2019 08:37:17) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.3.5, Copyright (c) 1998-2018 Zend Technologies
我无法安装 PHP 5.6（我需要 5.6 版本，因为旧网页需要该版本）。我需要在 CentOS 7 上安装 PHP 5.6。
