Raspberry Pi 3 with openSUSE Leap 15 小記

Hardware: Raspberry Pi 3

OS: openSUSE Leap 15

圖片取自網路: https://en.opensuse.org/File:Raspberry-Pi3.png

距離上次安裝 Raspberry Pi 已經 8 個月了 :)

參考:

我還是使用 X11 的桌面環境

下載 http://download.opensuse.org/ports/aarch64/distribution/leap/15.0/appliances/ 內的

將 SD Card 插入 linux 內, 這邊以 /dev/sdf 為例

使用下列指令建立 openSUSE Leap 15 with RaspberryPi

下面的 /dev/sdf 是你的 SD Card 千萬不要殺錯人

# xzcat openSUSE-Leap15.0-ARM-X11-raspberrypi3.aarch64-2018.07.02-Buildlp150.1.1.raw.xz | dd bs=4M of=/dev/sdf iflag=fullblock oflag=direct ; sync

好了之後將 SD Card 放入 Raspberry Pi 開機就可以

第一次因為要安裝, 所以會比較久, 去喝個咖啡動一動吧
預設帳號是 root 密碼是 linux

這個版本就沒有無線網路的 bug, 所以使用 #yast2 lan 設定好無線之後就直接使用

netbox with docker in azure

看到 digital ocean 出了一個專案 netbox 就想說來試試看

https://github.com/digitalocean/netbox

上面看到有人有做 docker 的版本

https://github.com/ninech/netbox-docker

OS: openSUSE Leap 42.3 in Azure

首先登入 Azure 的 openSUSE Leap 42.3

切換成 root

> sudo su -

啟動 docker 服務

# systemctl start docker

安裝 docker-compose 指令

# zypper install docker-compose

Clone 專案

# git clone -b master https://github.com/ninech/netbox-docker.git

Cloning into 'netbox-docker'...

Receiving objects: 100% (652/652), 214.17 KiB | 5.22 MiB/s, done.

Resolving deltas: 100% (355/355), done.

觀察資訊

# ls

.bash_history .gnupg bin netbox-docker

進到專案目錄

# cd netbox-docker/

openSUSE Leap 42.3 預設用的 docker-compose 版本比較舊 ( 1.8.1 )

openSUSE Leap 15 版本就夠新了1.17

參考官方網站安裝方式 https://docs.docker.com/compose/install/#install-compose

先移除舊版的 docker-compose 1.8.1

# zypper remove docker-compose

The following package is going to be REMOVED:

docker-compose

1 package to remove.

After the operation, 512.8 KiB will be freed.

Continue? [y/n/...? shows all options] (y): y

(1/1) Removing docker-compose-1.8.1-13.1.noarch ..................................................................................[done]

下載最新版的 docker-compose

# sudo curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose

可以觀察 docker-compose.yml 或是 docker ps 知道, 目前走 port 32768

也可以使用指令查詢

# /usr/local/bin/docker-compose port nginx 8080

0.0.0.0:32768

在 Azure 上面的網路安全群組開放 port 32768

http://YOUR_SERVER_IP:PORT

點選右上方的 login

輸入預設的帳號 admin

密碼 admin

進行登入

使用 admin 登入之後就可以針對 Site 還有其他的物件進行新增以及修改

不過當然第一要務就是去修改密碼吧 :)

然後預設建立的 API Token 應該也可以刪除重新建立

看了一下, 目前沒有語系以及中文化設定

但是也是一個管理機櫃或是機器的好選項

找天來嘗試一下管理

Nextcloud with docker 測試小記

Server:

OS: openSUSE Leap 42.3 in Azure

Client:
OS: openSUSE Leap 42.3

因為 dropbox linux client 未來有可能不支援非加密 EXT4 以外的檔案系統, 所以就來想替代方案, 目前鎖定 nextcloud, 而且他也有 docker 的版本

官方網站 https://nextcloud.com/

連線到 openSUSE Leap 42.3 in Azure

切換為 root

>sudo su -

啟動 docker 服務

# systemctl start docker

一開始先來測試單一容器 + HTTP 存取

Lab1: 單一容器 + HTTP存取

Server 端:

執行 nextcloud 容器

# docker run -d -p 80:80 nextcloud

# docker ps

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

60e3b19053a3 nextcloud "/entrypoint.sh ap..." 7 seconds ago Up 5 seconds 0.0.0.0:80->80/tcp friendly_easley

在 Azure 設定 security group 允許 port 80 通過

連線 nextcloud (預設使用 SQL-Lite)

http://YOUR_SERVER_IP

一開始會建立管理者帳號

輸入使用者名稱 / 密碼 -- > 點選完成設定

就會順利完成設定, 無痛完成

Client 端:

OS: openSUSE Leap 42.3

接下來就是安裝 Client 的應用程式

參考 https://eiosifidis.blogspot.com/2017/06/nextcloud-client-for-distros.html

使用 zypper 安裝

# zypper install nautilus-extension-nextcloud nextcloud-client

Loading repository data...

Reading installed packages...

Resolving package dependencies...

The following 17 NEW packages are going to be installed:

libQt5Positioning5 libQt5Sensors5 libQt5Sensors5-imports libQt5WebChannel5

libQt5WebChannel5-imports libQt5WebKit5 libQt5WebKit5-imports

libQt5WebKitWidgets5 libgypsy0 libnextcloudsync0 libqt5keychain1

libqt5keychain1-lang nautilus-extension-nextcloud nextcloud-client

nextcloud-client-lang python-nautilus typelib-1_0-Nautilus-3_0

The following 2 recommended packages were automatically selected:

libqt5keychain1-lang nextcloud-client-lang

The following package is suggested, but will not be installed:

nextcloud-client-doc

17 new packages to install.

Overall download size: 11.0 MiB. Already cached: 0 B. After the operation,

additional 44.9 MiB will be used.

Continue? [y/n/...? shows all options] (y):

安裝完成之後, 就可以執行 Nextcloud desktop 程式

一開始會出現Nextcloud精靈 ( 翻譯沒有很準確 )

輸入伺服器位置 -- > 下一個

輸入使用者名稱與密碼 -- > 下一個

設定要同步的選項 -- > 點選連線中

因為有跟檔案總管整合, 所以可以使用瀏覽器的方式或是資料夾的方式 -- > 點選　完成

預設會在 $HOME/nextcloud , 可以觀察同步狀況

Lab2: 2個容器( nextcloud & MariaDB ) + HTTP存取

Nextcloud 預設使用 SQLite, 但是他有建議, 如果是用桌面版程式同步, 就不建議用 SQLite

要使用 MySQL / MariaDB 或是其他的資料庫

接下來就來實作使用 2個容器 nextcloud 與 mariadb 來提供服務

Server 端:

接下來嘗試使用 MySQL / MariaDB 方式

將剛剛的 container 刪除 ( 使用 docker stop / docker rm )

參考官方的方式 https://github.com/nextcloud/docker

使用 docker-compose 方式來建立

首先要先安裝 docker-compose 指令

使用 zypper 安裝

# zypper install docker-compose

Loading repository data...

Reading installed packages...

Resolving package dependencies...

The following 32 NEW packages are going to be installed:

docker-compose python-PySocks python-PyYAML python-appdirs python-backports python-backports.ssl_match_hostname

python-cached-property python-certifi python-cffi python-chardet python-cryptography python-docker-py python-docker-pycreds

python-dockerpty python-docopt python-enum34 python-functools32 python-idna python-ipaddress python-jsonschema python-ndg-httpsclient

python-packaging python-py python-pyOpenSSL python-pycparser python-pyparsing python-requests python-setuptools python-six

python-texttable python-urllib3 python-websocket-client

The following 5 recommended packages were automatically selected:

python-PySocks python-cryptography python-idna python-ndg-httpsclient python-pyOpenSSL

32 new packages to install.

Overall download size: 3.2 MiB. Already cached: 0 B. After the operation, additional 15.3 MiB will be used.

Continue? [y/n/...? shows all options] (y): Y

參考官方的設定建立 docker-compose.yml 檔案

檔案內紅色字體內, 請自行設定 MySQL 的密碼
我把官方的 port 8080 改為 port 80

# vi docker-compose.yml

version: '2'

volumes:

nextcloud:

db:

services:

db:

image: mariadb

restart: always

volumes:

- db:/var/lib/mysql

environment:

- MYSQL_ROOT_PASSWORD=nextcloud

- MYSQL_PASSWORD=nextcloud

- MYSQL_DATABASE=nextcloud

- MYSQL_USER=nextcloud

app:

image: nextcloud

ports:

- 80:80

links:

- db

volumes:

- nextcloud:/var/www/html

restart: always

使用 docker-compose 指令建立

# docker-compose up -d

接下來連線到 nextcloud

http://YOUR_SERVER_IP

要注意的是

資料庫要選 MySQL / MariaDB
資料庫帳號密碼要使用 docker-compose.yml 內的設定
主機的部份因為是使用 docker, 然後是分開的 container, 這邊就用 db:3306

觀察相關資訊

# docker ps

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

de1741e2abae nextcloud "/entrypoint.sh ap..." 27 seconds ago Up 24 seconds 0.0.0.0:80->80/tcp root_app_1

296498164d13 mariadb "docker-entrypoint..." 29 seconds ago Up 26 seconds 3306/tcp root_db_1

Client 的連線方式一樣, 就不重複了

接下來文章再來挑戰, HTTPS 方式

也算往 nextcloud 邁進一步
