The mcrypt extension is missing. Please check your PHP configuration.

[testing]

First do fresh installation of your OS.

Then use this command :

Code:

yum remove -y httpd httpd-devel php php-devel php-gd php-mbstring php-intl php-mysql php-xml php-xmlrpc php-mcrypt php-imap php-pear php-mysql php-cli php-common php5-dev myself mysql dovecot-mysql MariaDB MariaDB-common MariaDB-compat MariaDB-server phpMyAdmin postfix dovecot dovecot-mysql dovecot-pigeonhole sendmail ProFTPd proftpd proftpd-mysql vsftpd named bind bind-utils bind-libs bind9 pdns pdns-backend-mysql pdns-server pdns-server-backend-mysql webalizer crontabs

yum clean all

And then install Sentora, see if it works. I used this method and it worked for me.
