distributed storage

"Torus is an open source project for distributed storage coordinated through etcd. Torus provides a resource pool and basic file primitives from a set of daemons running atop multiple nodes. These primitives are made consistent by being append-only and coordinated by etcd. From these primitives, a Torus server can support multiple types of volumes, the semantics of which can be broken into subprojects. It ships with a simple block-device volume plugin, but is extensible to more."

Linux就是核心與系統呼叫介面那兩層
...

Cancel
核心與硬體的關係非常的強烈
...

Cancel
Linux提供了一個完整的作業系統當中最底層的硬體控制與資源管理的完整架構，這個架構是沿襲Unix良好的傳統來的，所以相當的穩定而功能強大
...

Linux的核心是由Linus Torvalds在1991年的時候給他開發出來的，並且丟到網路上提供大家下載，後來大家覺得這個小東西(Linux Kernel)相當的小而精巧，所以慢慢的就有相當多的朋友投入這個小東西的研究領域裡面去
...

Cancel
1960年代初期麻省理工學院(MIT)發展了所謂的：『相容分時系統(Compatible Time-Sharing System, CTSS)』，它可以讓大型主機透過提供數個終端機(terminal)以連線進入主機，來利用主機的資源進行運算工作
...

Cancel
為了更加強化大型主機的功能，以讓主機的資源可以提供更多使用者來利用，所以在1965年前後，由貝爾實驗室(Bell)、麻省理工學院(MIT)及奇異公司(GE, 或稱為通用電器)共同發起了Multics的計畫
...

Cancel
以組合語言(Assembler)寫出了一組核心程式，同時包括一些核心工具程式，以及一個小小的檔案系統。那個系統就是Unix的原型！當時Thompson將Multics龐大的複雜系統簡化了不少，於是同實驗室的朋友都戲稱這個系統為：Unics。(當時尚未有Unix的名稱)
...

Cancel
所有的程式或系統裝置都是檔案
...

Cancel
不管建構編輯器還是附屬檔案，所寫的程式只有一個目的，且要有效的完成目標。
...

Cancel
Dennis Ritchie (註3) 將B語言重新改寫成C語言，再以C語言重新改寫與編譯Unics的核心，最後正名與發行出Unix的正式版本！
...

Cancel
由於Unix是以較高階的C語言寫的，相對於組合語言需要與硬體有密切的配合，高階的C語言與硬體的相關性就沒有這麼大了！所以，這個改變也使得Unix很容易被移植到不同的機器上面喔！
...

Cancel
AT&T此時對於Unix是採取較開放的態度，此外，Unix是以高階的C語言寫成的，理論上是具有可移植性的！亦即只要取得Unix的原始碼，並且針對大型主機的特性加以修訂原有的原始碼(Source Code)，就可能將Unix移植到另一部不同的主機上頭了。
...

Cancel
柏克萊大學的Bill Joy (註4)在取得了Unix的核心原始碼後，著手修改成適合自己機器的版本，並且同時增加了很多工具軟體與編譯程式，最終將它命名為Berkeley Software Distribution (BSD)。
...

Cancel
每一家公司自己出的Unix雖然在架構上面大同小異，但是卻真的僅能支援自身的硬體，所以囉，早先的Unix只能與伺服器(Server)或者是大型工作站(Workstation)劃上等號！
...

Cancel
AT&T在1979年發行的第七版Unix中，特別提到了『不可對學生提供原始碼』的嚴格限制！
...

Cancel
純種的Unix指的就是System V以及BSD
...

Cancel
AT&T自家的System V
...

Cancel
既然1979年的Unix第七版可以在Intel的x86架構上面進行移植，那麼是否意味著可以將Unix改寫並移植到x86上面了呢？在這個想法上，譚寧邦教授於是乎自己動手寫了Minix這個Unix Like的核心程式！
...

Cancel
『既然作業系統太複雜，我就先寫可以在Unix上面運行的小程式，這總可以了吧？』
...

Cancel
如果能夠寫出一個不錯的編譯器，那不就是大家都需要的軟體了嗎？因此他便開始撰寫C語言的編譯器，那就是現在相當有名的GNU C Compiler(gcc)！
...

Cancel
他還撰寫了更多可以被呼叫的C函式庫(GNU C library)，以及可以被使用來操作作業系統的基本介面BASH shell！這些都在1990年左右完成了！
...

Cancel
有鑑於圖形使用者介面(Graphical User Interface, GUI) 的需求日益加重，在1984年由MIT與其他協力廠商首次發表了X Window System ，並且更在1988年成立了非營利性質的XFree86這個組織。所謂的XFree86其實是 X Window System + Free + x86的整合名稱呢！
...

Cancel
譚寧邦教授為了教育需要而撰寫的Minix系統！他在購買了最新的Intel 386的個人電腦後，就立即安裝了Minix這個作業系統。另外，上個小節當中也談到，Minix這個作業系統是有附上原始碼的，所以托瓦茲也經由這個原始碼學習到了很多的核心程式設計的設計概念喔！
...

Cancel
托瓦茲自己也說：『我始終是個性能癖』^_^。為了徹底發揮386的效能，於是托瓦茲花了不少時間在測試386機器上！他的重要測試就是在測試386的多功性能。首先，他寫了三個小程式，一個程式會持續輸出A、一個會持續輸出B，最後一個會將兩個程式進行切換。他將三個程式同時執行，結果，他看到螢幕上很順利的一直出現ABABAB...... 他知道，他成功了！ ^_^
...

Cancel
為了讓所有的軟體都可以在Linux上執行，於是托瓦茲開始參考標準的POSIX規範。
...

Cancel
POSIX是可攜式作業系統介面(Portable Operating System Interface)的縮寫，重點在規範核心與應用程式之間的介面，這是由美國電器與電子工程師學會(IEEE)所發佈的一項標準喔
...

Cancel
因為托瓦茲放置核心的那個FTP網站的目錄為：Linux，從此，大家便稱這個核心為Linux了。(請注意，此時的Linux就是那個kernel喔！另外，托瓦茲所丟到該目錄下的第一個核心版本為0.02呢！)
...

Cancel
Linux其實就是一個作業系統最底層的核心及其提供的核心工具。他是GNU GPL授權模式，所以，任何人均可取得原始碼與可執行這個核心程式，並且可以修改。
...

Cancel
Linux參考POSIX設計規範，於是相容於Unix作業系統，故亦可稱之為Unix Like的一種
...

Cancel
為了讓使用者能夠接觸到Linux，於是很多的商業公司或非營利團體，就將Linux Kernel(含tools)與可運行的軟體整合起來，加上自己具有創意的工具程式，這個工具程式可以讓使用者以光碟/DVD或者透過網路直接安裝/管理Linux系統。這個『Kernel + Softwares + Tools + 可完整安裝程序』的咚咚，我們稱之為Linux distribution，一般中文翻譯成可完整安裝套件，或者Linux發佈商套件等。
...

Cancel
在1994年終於完成的Linux的核心正式版！version 1.0。這一版同時還加入了X Window System的支援呢！且於1996年完成了2.0版、2011 年釋出 3.0 版，更於 2015 年 4 月釋出了 4.0 版哩！發展相當迅速喔！此外，托瓦茲指明了企鵝為Linux的吉祥物。
...

Cancel
Linux本身就是個最陽春的作業系統，其開發網站設立在http://www.kernel.org，我們亦稱Linux作業系統最底層的資料為『核心(Kernel)』。
...

Cancel
常見的 Linux distributions 分類有『商業、社群』分類法，或『RPM、DPKG』分類法
...

Cancel
事實上鳥哥認為distributions主要分為兩大系統，一種是使用RPM方式安裝軟體的系統，包括Red Hat, Fedora, SuSE等都是這類；一種則是使用Debian的dpkg方式安裝軟體的系統，包括Debian, Ubuntu, B2D等等。
