CentOS 7 provides PHP version 5.4 in its official repository. In order to upgrade to PHP 7.x follow the instructions listed below.

1. Remove the old version of PHP. This will also remove the WANconsole package because it`s a PHP dependency. No data or configurations will be lost. The WANconsole package will be later installed.

   yum remove php*
   

2. Install the EPEL repository configuration package

   yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
   

3. Install the Remi repository configuration package

   yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
   

4. Install the yum-utils package

   yum install yum-utils

6. Update

   yum update
   

7. Install PHP 7.2

   yum install php php-pecl-mysql php-cli php-common php-gd php-ldap php-mbstring php-mysql php-pdo php-pear php-pecl-radius php-process php-snmp php-xml
   

8. Install the Wanguard Console
