Overview

Brief notes about how to install RMT (Repository Mirror Tool) on SuSE 15.x. The audience is experienced Linux administrators.
NOTE: Do not install Apache; on SuSE it uses Nginx. Official Documentation:https://documentation.suse.com/sles/15-SP1/single-html/SLES-rmt/index.html

Register

Verify server is registered with SUSE via regular registration procedures: yast, Product Registration.
Verify online repos are populated:

# zypper refresh
# zypper repos

Install RMT

Install the repository mirror too. If not already setup, then MySQL will also be installed.

# zypper in rmt-server
# rcmysql start
# rcnginx start
# systemctl enable mariadb
# systemctl enable nginx

Setup MySQL Password

# set +o history
# mysqladmin -u root password 'password'
# set -o history
# mysql -u root -p
>show databases;
>quit

RMT Setup

# yast, 
	Network Services, RMT Configuration.

To get credentials: ssc.suse.com, Proxies, top right, click on eye:

Database username: rmt
Password: <select password>
CA Private Key Password: <select password>

Setup firewall rules

# firewall-cmd --get-active-zones
# firewall-cmd --list-all --zone=internal
# firewall-cmd --zone=internal --add-service=snmp
# firewall-cmd --zone=internal --add-service=http
# firewall-cmd --zone=internal --add-service=https
# firewall-cmd --zone=internal --add-service=ftp
# firewall-cmd --zone=internal --add-service=squid
# firewall-cmd --zone=internal --add-service=nfs
# firewall-cmd --zone=internal --add-service=nfs3
# firewall-cmd --zone=internal --add-service=syslog
# firewall-cmd --zone=internal --permanent --add-port=427/tcp
# firewall-cmd --zone=internal --permanent --add-port=427/udp
# firewall-cmd --runtime-to-permanent
# firewall-cmd --reload

Enable SLP Broadcast

# zypper install openslp-server
# systemctl enable slpd.service
# systemctl restart slpd.service

View RMT Server Status

Look at trigger section for the time it will be udpated.

# systemctl status rmt-server-sync.timer

View Products and Repos:

# rmt-cli products list --all
# rmt-cli repos list --all

View installed products and repos:

# rmt-cli products list
# rmt-cli repos list

Install Repos

Install the repos and packages for SuSE 12 SP4, 12 SP5, 15 SP1, syncronize, then mirror.

# rmt-cli products enable SLES/12.4/x86_64 SLES/12.5/x86_64 SLES/15.1/x86_64 

Mirror Repos

:

#rmt-cli products enable 1625 1878 1763

# rmt-cli sync 
# rmt-cli mirror

Setup RMT Clients

Setup the other servers to register and install packages via the repo servers:

# wget http://test-repo1/tools/rmt-client-setup
# sh rmt-client-setup https://test-repo1.example.com
	Do you accept this certificate? [y/n] y
	Start the registration now? [y/n] y

# zypper refresh
# zypper repos
# zypper list-updates
# zypper update

Install a test package mc (midnight commander):

# zypper install mc
# zypper info mc
# zypper packages
# mc

Add Repo Install Directories

Upload ISOs and mount them, ready for local over the LAN install:

http://test-repo1.example.com/pub/suse/suse-12-sp4/dvd1
http://test-repo1.example.com/pub/suse/suse-15-sp1/dvd1
http://test2-repo1.example.com/pub/suse/suse-12-sp4/dvd1
http://test2-repo1.example.com/pub/suse/suse-15-sp1/dvd1

Create Mini ISOs

The mini ISOs will be 90MB to 100MB; makes for faster and easier remote installs over the LAN while using the repo servers. Place them in the same directory as the original ISOs:

# mksusecd --create SLE-15-SP1-mini.iso --nano SLE-15-SP1-Installer-DVD-x86_64-GM-DVD1.iso
# mksusecd --create SLE-12-SP4-mini.iso --nano SLE-12-SP4-Server-DVD-x86_64-GM-DVD1.iso

Remove RMT Clients

To remove a client from the RMT database:

# SUSEConnect --de-register
# SUSEConnect --cleanup
# rm -f /etc/SUSEConnect
# rm -rf /etc/zypp/credentials.d/*
# rm -rf /etc/zypp/repos.d/*
# rm -f /etc/zypp/services.d/*
