``` - 現在怎麼去用它們呢 - 為什麼要定義多個池子,加入 test .com 請求很大,最終把程式耗盡了php-fpm ,最多啟動50個,結果啟動完50個 所有的都在忙,又有新的請求的時候,結果就報502錯誤,因為他沒有多餘的php 程式給它提供服務,而這個站點不受影響,因為他用的是另一個池子,這就是為什麼要定義多個池子的原因。

``` - 多個池子就這樣配置 # 12.22 php-fpm慢執行日誌 - 我們們做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,為什麼要分析它的 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裡,就像系統負載高可以用工具去分析,vmstat top 等等,可以找到哪個程式導致的,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 ``` [root@localhost php-fpm.d] # vi www.conf

``` - 看看它有沒有內容呢,空的,因為你還沒有任何的超過1秒的 php執行的過程 - 接下來需要模擬一個慢執行的php - 我們們來寫一個指令碼 - php-fcgi 它是被這個( /usr/local/nginx/conf/vhost/test .com.conf
) test .com.conf站點用著 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

``` - 出錯誤了,排查錯誤看日誌,也有個簡單的方法,直接開啟它的配置檔案,搜尋display_error 把display_errors = On - 可以直接檢視到具體的錯誤是什麼 ``` [root@localhost php-fpm.d] # vi /usr/local/php-fpm/etc/php.ini

``` - 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,它會告訴你是這個指令碼慢,指令碼的第三行慢 /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

[root@localhost php-fpm.d] #
``` - 看下第三行 sleep (2); 是這一行,因為它執行了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] #
``` - 我們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,如果你伺服器上有多個網站,去php.ini就不合適了,所以要麼去apache虛擬主機配置檔案裡定義,要麼去php-fpm配置檔案裡去定義,可以針對每個池子做不同的定義 - 比如我在www裡面去定義 ``` [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/
[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

``` - 看下日誌裡有沒有資訊, 很明顯地址 open_basedir restriction in effect 有限制
- . 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 ``` [root@localhost php-fpm.d] # cat /usr/local/php-fpm/var/log/php_errors.log

``` - 現在可以了,這次就正常了,這就是openbasedir怎麼去定義 # 12.24 php-fpm程式管理 ``` [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/test .com: /tmp/
[root@localhost php-fpm.d] #
``` - pm = dynamic 表示以什麼樣的形式程式啟動,用dynamic 動態,後面引數才會生效, - 如果是靜態,只有一行生效 pm.max_children = 50 其他後面的引數不會生效 - pm = dynamic // 動態程式管理,
- 也可以是static(靜態) 也就是我一下子記生成這麼多 - pm.max_children = 50 // 最大子程式數, ps aux可以檢視
- pm.start_servers = 20 // 啟動服務時會啟動的程式數
- pm.min_spare_servers = 5 // 定義在空閒時段,子程式數的最少數量,如果達到這個數值時,php-fpm服務會自動派生新的子程式。
- pm.max_spare_servers = 35 // 定義在空閒時段,子程式數的最大值,如果高於這個數值就開始清理空閒的子程式。
- // 定義一個子程式最多處理的請求數,也就是說在一個php-fpm的子程式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。
