1. 環境要求

RMT Server
- cpu: 4 Core
- memory: 8 G
- 可以連上外網
- os iso: SLE-15-SP4-Full-x86_64-QU3-Media1.iso
已安裝好 SUSE Manager Server
- Version: 4.3.12

2. Application components 介紹

Each component of the RMT application is deployed in its own container. RMT consists of the following components:

RMT server

Containerized version of the RMT application server with the ability to pass its configuration via Helm values. Storage is done on a volume that will be allocated on the Kubernetes cluster. You need to adjust the size of the storage depending on the number of repositories you need to mirror.

What is RMT?
RMT is stand for “Repository Mirroring Tool”. It allows enterprise customers to optimize the management of SUSE Linux Enterprise software updates and subscription entitlements. It establishes a proxy system for SUSE® Customer Center with repositories and registration targets. This helps you to centrally manage software updates within a firewall on a per-system basis, while maintaining your corporate security policies and regulatory compliance.

MariaDB

The database back-end for RMT. RMT creates the required database and tables at start-up, therefore no specific post-installation task is required. If passwords are not specified in the values.yaml file, they are generated automatically.

Nginx

A Web server configured for RMT routes. Having a properly configured Web server allows you to target your Ingress traffic (for RMT) to this Nginx service directly. You do not need to configure Ingress for RMT specific paths handling, as Nginx is configured to take care of this itself.

3. OS 設定

裝 SLES 15 SP4 minimal 版

# 1. 安裝必要套件
$ zypper mr -ea
$ zypper -n in iputils yast2-network sudo wget iptables bind-utils mkisofs yast2-ntp-client
$ sudo init 6

# 2. 設定當前使用者執行 sudo 免密碼
$ curl -s https://raw.githubusercontent.com/braveantony/bash-script/main/init.sh | bash

# 3. 設定網路
$ sudo yast2 lan edit id=0 ip=192.168.11.29 netmask=255.255.255.0
$ sudo ip route add default via 192.168.11.254
$ echo 'default 192.168.11.254 - eth0' | sudo tee /etc/sysconfig/network/ifroute-eth0
$ sudo yast2 dns edit nameserver1=192.168.11.85
$ sudo hostnamectl set-hostname rmt-server

# 4. 加一顆 500G Disk，之後要儲存 Repo 的資料
$ sudo fdisk /dev/sdb
Command (m for help): n
Partition type
   p   primary (0 primary, 0 extended, 4 free)
   e   extended (container for logical partitions)
Select (default p): e

Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-1048575999, default 1048575999):

Created a new partition 1 of type 'Linux' and of size 500 GiB.

Command (m for help): t

$ sudo /sbin/pvcreate /dev/sdb1
$ sudo /sbin/vgcreate rmt-data-vg /dev/sdb1
$ sudo /sbin/lvcreate -l 100%FREE -n rmt-data rmt-data-vg

# 5. Check LVM Settings
$ sudo pvs

  home     system      -wi-ao----  25.00g
  root     system      -wi-ao----  40.00g

# 6. 將 LVM 格式化成 XFS 檔案系統
$ sudo /sbin/mkfs.xfs /dev/rmt-data-vg/rmt-data

# 7. 建立 RMT Server 儲存資料的目錄區
$ sudo mkdir -p /var/lib/rancher/k3s/storage

# 8. 設定開機自動將指定的 LV 掛載到指定的目錄區
$ echo '/dev/rmt-data-vg/rmt-data  /var/lib/rancher/k3s/storage  xfs  defaults 0 0' | sudo  tee -a /etc/fstab && sudo mount -a

# 9. 檢查是否掛載成功
$ lsblk /dev/sdb
NAME                        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
sdb                           8:16   0  500G  0 disk

預設每小時會執行 rmt-cli sync，每天的凌晨 2 點 30 分鐘執行 rmt-cli mirror

6. 下載 Packages Repositories

# 1. Enable SLES for sap 12 sp5
$ rmt_server=$(kubectl get pods --no-headers -l component=app -o custom-columns=Name:.metadata.name)

# 2. 到 SUMA Web UI 確認要下載的 repos
## 以下載 SUSE Linux Enterprise Server for SAP Applications 12 SP5 x86_64 這個產品的所有必要的套件儲存庫為例
## 連到 SUSEManager Web UI ，點選左側選單的 Admin > Setup Wizard > Products > SUSE Linux Enterprise Server for SAP Applications 12 SP5 x86_64 > Show Product's channels (右邊 4 條槓的藍色按鈕)，會看到以下輸出

2. 掛 ISO 檔

$ mkdir /var/lib/rmt-data/{mirrorrepo,iso}

$ mount -o loop /var/lib/rmt-data/SLES-12-SP5-SAP.iso /var/lib/rmt-data/iso

$ cd /var/lib/rmt-data/ && \
ls -l iso/
total 15284

3. 修改設定檔 `/etc/rhn/rhn.conf`

$ echo "server.susemanager.fromdir = /var/lib/rmt-data/mirrorrepo/" >> /etc/rhn/rhn.conf

4. Restart the Tomcat service

$ systemctl restart tomcat

5. Refresh the local data:

$ mgr-sync -v -d 3 refresh

6. List Chaneel

$ mgr-sync list channels
Available Channels:


Status:
  - [I] - channel is installed
  - [ ] - channel is not installed, but is available
  - [U] - channel is unavailable

[ ] EL9-Pool for x86_64 RHEL and Liberty 9 Base [el9-pool-x86_64]
[ ] RHEL5-Pool for i386 RHEL5 Base i386 [rhel5-pool-i386]
[ ] RHEL5-Pool for x86_64 RHEL5 Base x86_64 [rhel5-pool-x86_64]

[ ] RHEL8-Pool for x86_64 RHEL and Liberty 8 Base [rhel8-pool-x86_64]
[ ] SLE12-SP5-SAP-Pool for x86_64 SUSE Linux Enterprise Server for SAP Applications 12 SP5 x86_64 [sle12-sp5-sap-pool-x86_64]
[ ] SLES12-SP5-Pool for x86_64 SUSE Linux Enterprise Server 12 SP5 x86_64 [sles12-sp5-pool-x86_64]

[ ] ubuntu-18.04-pool for amd64 Ubuntu 18.04 [ubuntu-18.04-pool-amd64]

7. Perform a synchronization

# 1. 同步 sle12-sp5-sap
$ mgr-sync add channel sle12-sp5-sap-pool-x86_64
Added 'sle12-sp5-sap-pool-x86_64' channel
Scheduling reposync for following channels:
- sle12-sp5-sap-pool-x86_64

# 2. 同步 sles12-sp5-pool
$ mgr-sync add channel sles12-sp5-pool-x86_64
Added 'sles12-sp5-pool-x86_64' channel
Scheduling reposync for following channels:
- sles12-sp5-pool-x86_64

Log 位置在 /var/log/rhn/reposync 目錄區

TroubleShooting

錯誤訊息如下 :

Refreshing Channel families                    [DONE]
Refreshing SUSE products                       [DONE]
Refreshing SUSE repositories                   [FAIL]
        Error: <Fault -1: 'redstone.xmlrpc.XmlRpcFault: unhandled internal exception: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect) : [com.redhat.rhn.domain.scc.SCCRepositoryTokenAuth#10229]'>

如果遇到以上錯誤訊息，要先刪 credentials

$ mgr-sync delete credentials
Credentials:
01) 9596e8825a (primary)
Enter credentials number (1-1): 1
Really delete credentials '9596e8825a'? (y/n): y
Successfully deleted credentials: 9596e8825a

然後在重新同步

$ mgr-sync -v -d 3 refresh
Refreshing Channel families                    [DONE]
Refreshing SUSE products                       [DONE]
