Samba AD on CentOS7
This page describe Samba4 Active Directory installation on CentOS. The environment is composed of 2 DCs with replication, and one fileserver.
dc1.domain.com.br dc2.domain.com.br fileserver.domain.com.br
The installation is based on CentOS7 Minimal ISO, you should update the system, and install basic tools.
yum update yum install -y vim wget
This pre-setup can be done in all 3 servers, basically it will setup the Sernet Samba Repository and install samba from repo.
wget https://raw.githubusercontent.com/hflautert/lotus7/master/samba4/pre_install_samba4.sh chmod +x pre_install_samba4.sh ./pre_install_samba4.sh
First of all we need a domain, so lets provision it.
samba-tool domain provision --use-rfc2307 --interactive
samba-tool domain join domain.com.br DC -Uadministrator --realm=domain.com.br
This post setup will configure the services to startup and disable Selinux and Firewall, during my tests the firewall did not save the allowed ports, even with permanent flag, so I´v decided to disable to avoid problems.
wget https://raw.githubusercontent.com/hflautert/lotus7/master/samba4/post_install_samba4.sh chmod +x post_install_samba4.sh ./post_install_samba4.
