一.系統I/O模型：

1.同步/異步：

關注的是事件處理的消息通信機制，即在等待⼀件事情的處理結果時，被調⽤者是否提供完成通知。
同步：synchronous，調⽤者等待被調⽤者返回消息后才能繼續執⾏，如果被調⽤者不提供消息返回則為同步，同步需要調⽤者主動詢問事情是否處理完成。
異步：asynchronous，被調⽤者通過事件狀態、通知或回調機制主動通知調⽤者，即異步會主動返回被調⽤者的狀態給調⽤者。

同步：進程發出請求調⽤后，內核不提供通知機制，即⽂件IO處理完成后不通知進程，需要進程⾃⼰去問內
核是否處理完成。
異步：進程發出請求調⽤后，內核會在調⽤處理完成后返回調⽤結果給進程,Nginx是異步的。

2.阻塞/⾮阻塞：

關注調⽤者在等待結果返回之前所處的狀態

阻塞：blocking，指IO操作需要徹底完成后才返回到⽤戶空間，調⽤結果返回之前，調⽤者被掛起，⼲不
了別的事情。
⾮阻塞：nonblocking，指IO操作被調⽤后⽴即返回給⽤戶⼀個狀態值，⽆需等到IO操作徹底完成，最終
的調⽤結果返回之前，調⽤者不會被掛起，可以去做別的事情。

3.系統IO模型組合：

以我去吃飯為例：我點了10個包⼦
同步與異步：
我點包⼦之后廚師是否告訴我：
同步：廚師做好包⼦后會放到指定位置，但是做好包⼦之前需要⾃⼰⼀次次去看包⼦做好沒有，廚師不
會在包⼦做好之后通知我。
異步：廚師做好包⼦后告訴我包⼦做好放哪了。
阻塞與⾮阻塞：：
我點包⼦后的狀態：
阻塞：在廚師做包⼦期間⼀直在包⼦盤⼦前⾯等着，不能⼲別的事情。
⾮阻塞：點完包⼦就可以去⼲別的事情，⽐如去逛逛街或者買買買。
IO模型組合：
同步阻塞：我點完包⼦后不能去做別的事情，⽽且不知道包⼦有沒有做好，需要⾃⼰⼀直等着並⼀次次的
問廚師做好沒有。
同步⾮阻塞：點完包⼦后可以去做別的事情，但是不能⻓時間做別的事情，因為我還是不知道包⼦有沒有
做好，也要⾃⼰⼀直等着並⼀次次的問廚師做好沒有，只能抽空做點別的。
異步阻塞：我點完包⼦后不能去⾛做別的事情，但是廚師在做好包⼦后會告訴我，也就是我不⽤再⼀次次
為廚師包⼦有沒有做好了。
異步⾮阻塞：我點完包⼦后可以做別的事情，⽽且可以⼀直在做別的去事情，因為廚師在做好包⼦后會告
訴我。

二.編譯安裝過程：

configure：檢查當前編譯環境，生成MakeFile

make：根據MakeFile生成相關模塊

make install：將模塊copy到指定目錄

三.nginx一鍵編譯安裝腳本
