A clientless remote desktop gateway. It supports standard protocols like VNC, RDP, and SSH. We call it clientless because no plugins or client software are required. Guacamole is installed on a server, all you need to access your desktops is a web browser.遠端桌面閘道(RD Gateway)支援 RDP 及 SSH 協定；使用者透過瀏覽器可直接存取遠端桌面，無需設定。
# apt-get -y update # apt-get install -y nodejs npm git # npm install pm2 -g # pm2 install pm2-logrotate安裝 Uptime Kuma
# git clone https://github.com/louislam/uptime-kuma.git # cd uptime-kuma # npm run setup # pm2 start server/server.js --name uptime-kuma進行初次設定 http://localhost:3001
Cookie 分區儲存，第三方 Cookie 只允許讀取同網域下的內容，無法跨站存取。
Cookies Having Independent Partitioned State (CHIPS) allows developers to opt a cookie into partitioned storage, with separate cookie jars per top-level site, improving user privacy and security.
Without partitioning, third-party cookies can enable services to track users and join their information from across many unrelated top-level sites. This is known as cross-site tracking.
停用方式：
[Chrome]
在 chrome://flags/ 中更改設定 Third-party Storage Partitioning = Disable
[Firefox]
在 about:config 中更改設定 network.cookie.cookieBehavior 改成 4
愈來愈嚴格！
因為 CodeIgniter v4.5 需要 PHP 8.1 及 PHP-intl 元件才能運作，原生 GitHub Codespaces 運作 Ubuntu 20.04 LTS 版本，快速解法是直接透過 Personal Package Archives(PPA) 補齊新版套件，並把環境鏈結刪除(current)，最後再用 composer 把 CodeIgniter 裝起來。
[啟用第三方套件庫]
# add-apt-repository ppa:ondrej/php
# apt install php8.3-{cli,intl,curl,mbstring,mysql,sqlite3,gd} phpunit
[確定當前PHP呼叫路徑]
# which php
# 可能是 /home/codespace/.php/current/bin/php
# 或者是 /usr/local/php/current/bin/php
[重新建立鏈結(current)，最新版位於 /usr/bin/php8.3]
# rm /home/codespace/.php/current
# rm /usr/local/php/current
# ln -s /usr /home/codespace/.php/current
# ln -s /usr /usr/local/php/current
# 執行 php --ini 或 php -m 驗證環境
[安裝資料庫]
# apt install mariadb-server
# /etc/init.d/mysql start
# mysql_secure_installation
git config --global user.name "Foo Bar" git config --global user.email foo@bar.com git config --global --list git config --global --list --show-origin
git init git checkout -b main // 建立並切換到 main 分支 git add . // 加入檔案到 staging git commit -m "first commit" // 加到本地 repository git remote add origin https://example.com/user/foo.git // git remote add [remote-name] [remote-url] git push -u origin main // 推送本地分支(main)到遠端位址(origin)[SSH]
git init git checkout -b main git add README.md git commit -m "first commit" git remote add origin git@github.com:user/foo.git // 透過 SSH 上傳需佈建公鑰(id_rsa.pub)在遠端 git push -u origin main[其他常用指令]
git log // 列出提交歷史 git status // 列出狀態 git remote -v // 列出遠端位址 git remote set-url origin// 更改遠端倉庫位址對應
1. 建立一個以 Ubuntu 為作業系統的虛擬機(當作空殼)
2. 到 Alpine Linux 官網下載 VIRTUAL 版本的映像檔。例如 alpine-virt-3.19.0-x86_64.iso
3. 刷入映像檔
# sudo dd if=alpine-virt-3.19.0-x86_64.iso of=/dev/sda
4. 重新開機
5. 使用 Oracle Cloud 主控台連線(console)操作，進行安裝前準備
# mkdir /media/setup # cp -a /media/sda/* /media/setup # mkdir /lib/setup # cp -a /.modloop/* /lib/setup # /etc/init.d/modloop stop # umount /dev/sda # mv /media/setup/* /media/sda/ # mv /lib/setup/* /.modloop/6. 循原本方式進行系統安裝(setup-alpine)，網路介面直接用 eth0(dhcp)。安裝後驚人的空間使用(僅150MB)
