当前，我的Centos6服务器具有PHP 5.6.40版本。我有一个需要PHP 7.2运行的laravel应用程序，因此我想升级我的php版本。我在外壳上尝试了以下命令，但未安装php7.2。这是命令：
＃yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
＃yum install http://rpms.remirepo.net/enterprise/remi-release-6.rpm
＃yum安装yum-utils
＃yum-config-manager-启用remi-php72
＃yum安装php php-mcrypt php-cli php-gd php-curl php-mysql php-ldap php-zip php-fileinfo
这是＃yum-config-manager --enable remi-php72
上的响应[root@s50-62-22-174 ~]# yum-config-manager --enable remi-php72
