Simplify adding repositories

[tukusejssirs]

You could add all repositories in some command.

# Current
yum -y install yum-utils epel-release
rpm -Uvh http://rpms.remirepo.net/enterprise/remi-release-7.rpm
rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm
rpm -Uvh https://yum.postgresql.org/10/redhat/rhel-7-x86_64/pgdg-centos10-10-2.noarch.rpm

# Proposed
yum -y install yum-utils epel-release http://rpms.remirepo.net/enterprise/remi-release-$(rpm -E %centos).rpm https://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm https://yum.postgresql.org/10/redhat/rhel-7-x86_64/pgdg-centos10-10-2.noarch.rpm

Moreover, you could enable the latest remi-php version available using the following command.

# Current
yum-config-manager --enable remi-php72

# Proposed
remi_php_latest="$(ls /etc/yum.repos.d/remi-php* | grep -Po 'remi-php[0-9]*' | tail -1)"
yum-config-manager --enable $remi_php_latest
