FPM 架構下執行一個 PHP 檔案後 nginx 如何與 PHP-FPM 程式管理器進行互動的 [硬核跟蹤底層資料互動詳細過程][非 CSDN 非百度瞎複製炒冷飯哦]

PHP直譯器騷操作

當我們要擼上LNMP或是LAMP環境時【不用具體細說了吧】，我們得裝上nginx/apache+mysql【其它資料庫也行】+PHP
一般來說PHP安裝好【習慣原始碼安裝了，yum或是docker或是其它騷方式安裝的朋友自行查詢】以後，目錄是這樣的【php.net官方手冊有安裝教程和說明，所以有空多讀讀php.net真的】

然後bin目錄有個PHP解析器【就是解析我們們擼的PHP原始碼】

php直譯器執行示例

解釋一下程式碼

是的，列印123

然後你覺得這有啥好說的？這麼so easy，不不不，大佬，真不是這樣的，下面我們們來玩玩php - r “echo 123;”後這個直譯器是怎麼處理的，然後又是怎麼列印出123的，這個時候你就會說，切，你不會去讀PHP直譯器原始碼啊？【來來你來讀https://github.com/php/php-src ，我渣渣不會^_^】

下面我們們執行:
strace ./php -r “echo 123;”
然後列印出這玩意【截圖，老實說有些人截圖特別小氣的，真的^_^】

PS:strace 工具請百度【本人不在此細說，一般工作幾年的大佬都懂，我就不在賣弄了】

strace ./php -r "echo 123;"
execve("./php", ["./php", "-r", "echo 123;"], [/* 26 vars */]) = 0   
//這裡我們得了解一下shell執行命令的過程，你登入系統後，你就是通過shell這個工具來和核心互動的，所以當然是在shell下輸入 strace ./php -r "echo 123;" ，然後呢簡單它會fork一個程式，同時呼叫exec系列函式【有哪些函式，請百度或是google嘛，年輕人】  
//shell 有內建命令和外部的應用了，具體可以瞭解shell程式設計嘛 
//./php 是執行指令碼的路徑
//後面就是傳遞給指令碼的引數啦
//自己用php寫個指令碼<?php print_r($argv); ?>然後 在控制檯執行它 看看效果 
//其它擼過半點c的知道int main(int arg,char *argv[]) 啦
//所以shell命令格式就是這樣騷操作的：command 選項  選項引數   引數 
//command 後面的引數就是$argv/char *argv[]接受的  
//所以你就知道在shell 執行命令，給相關引數就是為了傳遞引數給程式做處理的【解釋這麼多好累】   
//下面呢就是這個解析器執行的動態過程【程式執行的動態流程】
//有必要搞清楚程式和程式的區別  
//程式=指令的集合=靜態的檔案儲存在磁碟上  比如我們們擼的php程式碼或是其它程式碼 
//程式=我們們run它之後，它就是程式了【程式的例項】，程式執行時肯定是從第1句執行到最後一句結束【當然啦有可能中間就結束了，或是被其它中斷訊號搞掛了，或是遇到exit了，或是執行錯誤提前掛了，有興趣可以瞭解程式記憶體模型和執行流程】
//程式在執行的過程中呢是不是斷的進行系統呼叫system call的，就是從使用者空間跑到核心空間執行再返回
brk(0)                                  = 0x1d61000
//mmap 系統呼叫  功能就是搞個匿名記憶體對映【有興趣可以瞭解一下PHP程式間通訊，沒有興趣就算了】
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f2fdddd2000
//這些暫時不分析【其實擼過搞workerman開發或是swoole開發的人都懂，本人不在解釋了，我們往後瞧瞧就行了，中間這一大堆你看了也頭疼】

上面就是php直譯器執行程式碼時的流程【程式執行流程】

下面我們執行php test.php的結果

到這裡大家多少了解一些了，這個php直譯器就是讀取我們擼好的程式碼，然後這樣這樣【哪樣？自己看嘛 對於大佬分分鐘也瞭解了^_^】然後輸出內容了。

這個玩意是怎麼執行的，一般會說去讀原始碼，去百度【然後找出大堆重複的CSDN^_^】，分分鐘就知道了，我這裡就直接做測試它是如何執行的，下面的分析比較硬核，請做好心理準備

1. ./php-fpm啟動
2. nginx 啟動
   然後執行如下
   

然後它們都監聽了9000埠和2347埠【伺服器處於LISTEN狀態】，這個時候我們去看一下PHP-FPM到底以多少個程式執行的？是以什麼以樣的方式執行的？
3.pstree -ap |grep php-fpm
【我在laravel社群寫過php版本的master/worker工作模型的文章，有興趣的大佬可以看看】

現在呢我想知道worker工作程式，它現在在幹嘛？它到底在做什麼？【是在睡覺還是在做事情呢？】

![FPM 架構下執行一個 PHP 檔案後 nginx 如何與 PHP-FPM 程式管理器進行互動的 [硬核跟蹤資料互動]]

沒有錯master/worker總為3個程式執行在cpu的地盤上，現在我們來看worker程式在幹嘛

這個目錄是在程式執行時產生的【它會儲存程式執行期間的資料如程式的狀態，記憶體對映，所維護的檔案描述符表，資源限制等以及程式執行到哪】

程式的檔案維護列表

0,1,2是任何程式啟動後【程式預設自動開啟的檔案】，其它檔案是程式執行時開啟的其它檔案，檔案linux用整數字表示【有必要了解一上檔案描述符和檔案流即STREAM的關係，我這裡不在解釋】

這裡顯示了當前master程式的相關資訊，我們知道它現在睡於Sleeping【阻塞中，這個時候cpu是執行其它程式了，此程式阻塞，直到合適條件下才會喚醒此程式，所以有必要去學習一下PHP多程式程式設計哦】
現在我們它程式處在Sleeping中，那我想知道它到底是執行到哪個函式時阻塞的【如果非常熟悉php socket 或是workerman/swoole等網路應該瞭解阻塞，非阻塞，同步，非同步的概念】

wchan檔案是顯示當前程式執行到哪兒阻塞的，沒有錯執行到epoll_wait【它內部呼叫ep_poll】
這個時候呢就涉及到TCP/IP通訊了【所以本渣渣也在laravel社群釋出了關於此內容的文章，本人不會再細說了】
epoll_wait會讓程式阻塞【因為現在沒有資料可讀，什麼資料？就是socket 資料】
我們前面也說了我啟動PHP-FPM程式後，它啟動了一個TCP服務並監聽9000埠，說明什麼，說明它要進行TCP/IP通訊【要和我們後面說到的nginx進行通訊啊】

現在我們來看worker 程式

沒有錯，php worker子程式阻塞了，它在accept時產生了阻塞【因為現在沒有socket 客戶端連線，所以阻塞Sleeping著，cpu依然去執行其它程式了，accept只有等客戶端連線時才會喚醒此程式接受資料】【這裡我非常建議大家去看看我之前擼的TCP/IP php socket 程式設計，不然你看到這裡還是迷糊的】

現在我們知道PHP-FPM程式在阻塞狀態中【因為沒有連線，所以等著，等有小姐姐來了，再服務】

現在我們來看NGINX服務

nginx一樣有個MASTER主程式和一個工作程式

我們看到NGINX 的工作程式再阻塞中，在等客戶端連線【所以大家勿必學習PHP socket 程式設計或是看看本人擼的workerman註解】

以上我們知道啟動php-fpm/nginx之後 它們處於阻塞狀態中【知道它執行到EPOLL_WAIT]後阻塞的【所以對網路程式設計或是對workerman,swoole非常熟悉的人是能看懂這文章的^_^】

現在我們在瀏覽器端訪問
http://xxx/test.php
nginx配置是這樣的

然後在瀏覽器上執行

以上內容對於熟悉workerman/swoole/go/nodejs/java網路程式設計的人是非常容易理解的，如果確實理解困難請多多關注本人的文章，多看看就理解了

PS:說明，時間倉促不在對一些內容進行詳細解釋【如果說你有意可以加本人，然後給我介紹個女朋友這樣子，我會詳細跟你解釋的^_^】
