- 現在怎麼去用它們呢
- 爲什麼要定義多個池子，加入test.com 請求很大，最終把進程耗盡了php-fpm ，最多啓動50個，結果啓動完50個 所有的都在忙，又有新的請求的時候，結果就報502錯誤，因爲他沒有多餘的php 進程給它提供服務，而這個站點不受影響，因爲他用的是另一個池子，這就是爲什麼要定義多個池子的原因。

# 12.22 php-fpm慢執行日誌
- 咱們做PHP得網站，建議你使用LNMP，其中有一個原因在於我們可以去分析php的慢執行日誌，爲什麼要分析它的 慢執行日誌呢，運維工作中，經常會遇到一個問題
- 老闆會經常反饋，你們公司的網站訪問慢了，或者客戶說網站慢了，要知道根本原因，要知道慢在什麼地方，java網站先不說，php的網站有是辦法查到底慢在哪裏，就像系統負載高可以用工具去分析，vmstat top 等等，可以找到哪個進程導致的，php網站慢，到底什麼地方慢，所以這個慢日誌，非常重要，
- 針對www做一個實驗
```

- 接下來需要模擬一個慢執行的php
- 咱們來寫一個腳本
- php-fcgi 它是被這個（/usr/local/nginx/conf/vhost/test.com.conf
） test.com.conf站點用着 fastcgi_pass unix:/tmp/php-fcgi.sock;
所以你要去這個站點做一些操作了，在這個目錄下/data/wwwroot/test.com
```
[root@localhost php-fpm.d]# vim /data/wwwroot/test.com/sleep.php
<?php
echo “test slow log”;
sleep(2);
echo “done”;
?>
:wq
```
- 來測試下
```
[root@localhost php-fpm.d]# curl -x127.0.0.1:80 test.com/sleep.php -I
HTTP/1.1 200 OK
Server: nginx/1.12.1
Date: Mon, 23 Oct 2017 16:19:16 GMT
Content-Type: text/html; charset=UTF-8
Connection: keep-alive
X-Powered-By: PHP/5.6.30
[root@localhost php-fpm.d]#
```
- 出錯誤了，排查錯誤看日誌，也有個簡單的方法，直接打開它的配置文件,搜索display_error 把display_errors = On
- 可以直接查看到具體的錯誤是什麼
```
[root@localhost php-fpm.d]# vi /usr/local/php-fpm/etc/php.ini
; development version only in development environments, as errors shown to
; application users can inadvertently leak otherwise secure information.
; This is php.ini-development INI file.

display_errors = On
[root@localhost php-fpm.d]# vi /usr/local/php-fpm/etc/php.ini
[root@localhost php-fpm.d]# /etc/init.d/php-fpm reload
Reload service php-fpm done
[root@localhost php-fpm.d]# curl -x127.0.0.1:80 test.com/sleep.php
<br />
<b>Parse error</b>: syntax error, unexpected 'slow' (T_STRING), expecting ',' or ';' in <b>/data/wwwroot/test.com/sleep.php</b> on line <b>2</b><br />
[root@localhost php-fpm.d]#
```
- 提示語法錯誤，分號不對，雙引號不對，進去改下
```
[root@localhost php-fpm.d]# vi /data/wwwroot/test.com/sleep.php
<?php
echo "test slow log";
sleep(2);
echo "done";
?>
:wq
```
- 再來測試下,它會告訴你是這個腳本慢，腳本的第三行慢 /data/wwwroot/test.com/sleep.php:3
```
[root@localhost php-fpm.d]# vi /data/wwwroot/test.com/sleep.php
[root@localhost php-fpm.d]# curl -x127.0.0.1:80 test.com/sleep.php
test slow logdone
[root@localhost php-fpm.d]# cat /usr/local/php-fpm/var/log/www-slow.log
[24-Oct-2017 00:29:29] [pool www] pid 6123
script_filename = /data/wwwroot/test.com/sleep.php
[0x00007f06da03d298] sleep() /data/wwwroot/test.com/sleep.php:3
[root@localhost php-fpm.d]#
```
- 看下第三行 sleep(2); 是這一行，因爲它執行了2秒鐘，只要超過了1秒就會被記錄慢日誌，這就是慢日誌的功效了
```
[root@localhost php-fpm.d]# cat /data/wwwroot/test.com/sleep.php
<?php
echo "test slow log";
sleep(2);
echo "done";
?>
[root@localhost php-fpm.d]#
```
- 咱們估以的讓它執行慢的，然後生成慢日誌
# 12.23 open_basedir
- open_bassdir 之前也介紹了，在php-fpm 也可以定義的，如果你服務器上有多個網站，去php.ini就不合適了，所以要麼去apache虛擬主機配置文件裏定義，要麼去php-fpm配置文件裏去定義，可以針對每個池子做不同的定義
- 比如我在www裏面去定義
```
[root@localhost php-fpm.d]# vi www.conf
[www]
[www]
listen = /tmp/php-fcgi.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
request_slowlog_timeout = 1
slowlog = /usr/local/php-fpm/var/log/www-slow.log
php_admin_value[open_basedir]=/data/wwwroot/aming.com:/tmp/
~
:wq
[root@localhost php-fpm.d]# cat www.conf
[www]
listen = /tmp/php-fcgi.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
request_slowlog_timeout = 1
slowlog = /usr/local/php-fpm/var/log/www-slow.log
php_admin_value[open_basedir]=/data/wwwroot/aming.com:/tmp/
[root@localhost php-fpm.d]#
```
- 正常的話/tmp/php-fcgi.sock 是test.com，定義成aming.com 的話，去請求去訪問php，肯定會出問題
- 重啓下
```

- 404肯定就不對了，所以說是有問題的

- 現在我們再去定義一個php

- 修改下www.conf，你針對的地方是test.com 如果這個地方不去定義正確的路徑， 他就沒辦法去訪問
```

- . File(/data/wwwroot/test.com/3.php) is not within the allowed path(s): (/data/wwwroot/wwtest.com:/tmp/)
- 很明顯這倆個地址不同，所以就會報錯，就會有問題

- pm = dynamic 表示以什麼樣的形式進程啓動，用dynamic 動態，後面參數纔會生效，
- 如果是靜態，只有一行生效 pm.max_children = 50 其他後面的參數不會生效
- pm = dynamic //動態進程管理，
- 也可以是static（靜態） 也就是我一下子記生成這麼多
- pm.max_children = 50 //最大子進程數，ps aux可以查看
- pm.start_servers = 20 //啓動服務時會啓動的進程數
- pm.min_spare_servers = 5 //定義在空閒時段，子進程數的最少數量，如果達到這個數值時，php-fpm服務會自動派生新的子進程。
- pm.max_spare_servers = 35 //定義在空閒時段，子進程數的最大值，如果高於這個數值就開始清理空閒的子進程。
- pm.max_requests = 500 //定義一個子進程最多處理的請求數，也就是說在一個php-fpm的子進程最多可以處理這麼多請求，當達到這個數值時，它會自動退出。12.21 php-fpm的pool12.22 php-fpm慢執行日誌 12.23 open_basedir 12.24 php-fpm進程管理
