算法：RSA / DSA / ECDSA
    - 通常使用 RSA
    - ECDSA 尚未被 CA 廣泛支持
    - SSH 通常使用 RSA 和 DSA
    - 2048-bits RSA and DSA, at least 512-bits ECDSA
    - Passphrase
        - 確保 Key 可以安全地 存放、傳輸、備份
        - 每次重啓服務器或操作 Key 時候，都要輸入密碼

Application
    - app.locals：定義本地變量
    - app.mountpath：獲取 mounted 的 sub app 的路徑
    - app.all()：匹配所有 HTTP verbs
    - app.engine()：註冊渲染引擎
    - app.listen()：監聽端口
    - app.param()：給指定 paramter 添加 callback
    - app.set() / app.get( )：設置 / 獲取常量
    - app.user()：安裝中間件
        * 設置靜態文件訪問：app.use(express.static(__dirname + '/public'))

PID：標識和區分進程的 ID
    - 隨機分配
    - PPID：父進程的 ID
        * PID 為 1 的進程由內核創建的 init 進程

進程狀態
    - R(running, 0)
    - S(sleeping, 1)
    - D(disk sleep, 2)：不可中斷睡眠狀態
    - T(stopped, 4)

1. 本地生成公私钥：ssh-keygen -t rsa

2. 复制 id_rsa.pub 到 远端 .ssh/authorized_keys(权限：644)

3. 修改配置 /etc/ssh/sshd_config
    - RSAAuthentication yes 
    - PubkeyAuthentication yes
    - AuthorizedKeysFile     .ssh/authorized_keys
    - 可选：PasswordAuthentication no
