Primary Name Server Not Listed At Parent

Related to this, the only thing I skip wast the nmtui configuration, I left in automatic the ip4 configuration.
Because, every time I reboot from ovh's console rewrite this configuration to automatic.

Make son changes to install apache lasted version, php v5.6 & mariadb v10.
I had problems to apache, solved with this:
yum -y --disableplugin=priorities install php php-devel php-gd php-imap php-ldap php-mysql php-odbc php-pear php-xml php-xmlrpc php-pecl-apc php-mbstring php-mcrypt php-mssql php-snmp php-soap php-tidy curl curl-devel perl-libwww-perl ImageMagick libxml2 libxml2-devel mod_fcgid php-cli httpd-devel php-fpm wget

And to make work phpmyadmin with the follow modification:
yum -y install ntp httpd mod_ssl mariadb-server php php-mysql php-mbstring
yum -y --disableplugin=priorities install phpmyadmin

To install let's encrypt : yum install certbot-apache

That's all the changes.

 

If I follow the guide install MariaDB v5 or v7 I don't remember, I need v10, so I only create a file:
nano /etc/yum.repos.d/MariaDB.repo
# MariaDB 10.2 CentOS repository list - created 2017-09-19 02:18 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.2/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

Following MariaDB's site.

For php & phpmyadmin display version error if I don't put the --disableplugin=priorities

Ok, I will try a fresh install in case I made a mistake
I'm teacher I use this server for virtual education, so I had 1 week for fine tunning

Regards,

 

I had problem of error 500 in Debian with the Moodle plataform. That could never fix.
With the CentOS works like a charm, the only this is that I can't send or receive emails.
Maybe I should try Ubuntu.

Yes, I'm a teacher, newby on this thinks. But I want to use virtual education for my students as a support.

Regards,
