php-fpm的pool

爲了避免因多站點使用同一個pool時,如果一個站點訪問量過大導致資源耗盡出現問題，進而影響使用同一個pool的其他站點的正常運行，就需要對每個站點配置一個單獨的pool。實現方式和nginx的vhost差不多

編輯主配置文件

[root@akuilinux01 aming.com]# vim /usr/local/php-fpm/etc/php-fpm.conf
[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
include = etc/php-fpm.d/*.conf

重建多個pool

[root@akuilinux01 aming.com]# mkdir /usr/local/php-fpm/etc/php-fpm.d
[root@akuilinux01 aming.com]# cd !$
cd /usr/local/php-fpm/etc/php-fpm.d
[root@akuilinux01 php-fpm.d]# vim www.conf
[www]
listen = /tmp/php-fcgi.sock
#listen = 127.0.0.1:9000
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  
[root@akuilinux01 php-fpm.d]# vim aming.conf
[aming]
listen = /tmp/aming.sock
#listen = 127.0.0.1:9000
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
[root@akuilinux01 php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t
[18-Jun-2018 23:31:06] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful

PHP慢執行日誌

配置文件中加入下面兩行

[root@akuilinux01 ~]# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf
request_slowlog_timeout = 1
#當請求超過1秒開始記錄日誌
slowlog = /usr/local/php-fpm/var/log/www-slow.log
#日誌存放地址

測試

[root@akuilinux01 ~]# vim /data/wwwroot/test.com/sleep.php
<?php
echo "test slow log";
sleep(2);
echo "done";
?>
[root@akuilinux01 ~]# curl -x127.0.0.1:80 test.com/sleep.php
test slow logdone
[root@akuilinux01 ~]# cat /usr/local/php-fpm/var/log/www-slow.log 
[19-Jun-2018 08:58:20]  [pool www] pid 1451
script_filename = /data/wwwroot/test.com/sleep.php
[0x00007f4cadc922e0] sleep() /data/wwwroot/test.com/sleep.php:3

open_basedir

當一臺服務器跑多個站點時，可以使用openbasedir限定各個站點所能訪問的服務器上的目錄的範圍，就需要每個pool設定open basedir

[root@akuilinux01 ~]# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf
php_admin_value[open_basedir]=/data/wwwroot/eetest.com:/tmp/
#故意寫錯/data/wwwroot/eetest.com，正確是/data/wwwroot/test.com

進行測試

[root@akuilinux01 ~]# curl -x127.0.0.1:80 test.com/sleep.php -I
HTTP/1.1 404 Not Found
Server: nginx/1.14.0
Date: Tue, 19 Jun 2018 01:21:13 GMT
Content-Type: text/html; charset=UTF-8
Connection: keep-alive
X-Powered-By: PHP/5.6.30

再次更改www.conf，修改路徑，再次測試

[root@akuilinux01 ~]# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf 
[root@akuilinux01 ~]# /etc/init.d/php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm  done
[root@akuilinux01 ~]# curl -x127.0.0.1:80 test.com/sleep.php
test slow logdone

配置錯誤日誌

[root@akuilinux01 ~]# vim /usr/local/php-fpm/etc/php.ini
error_reporting = E_ALL
display_errors = Off
;error_log = syslog
error_log = /usr/local/php-fpm/var/log/php_errors.log
[root@akuilinux01 ~]# touch /usr/local/php-fpm/var/log/php_errors.log
[root@akuilinux01 ~]# chmod 777 /usr/local/php-fpm/var/log/php_errors.log
[root@akuilinux01 ~]# /etc/init.d/php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm  done

再次測試，測試前故意改錯

[root@akuilinux01 ~]# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf
php_admin_value[open_basedir]=/data/wwwroot/eetest.com:/tmp/
#故意寫錯/data/wwwroot/eetest.com，正確是/data/wwwroot/test.com

[root@akuilinux01 ~]# curl -x127.0.0.1:80 test.com/sleep.php -I

php-fpm進程管理

[root@akuilinux01 ~]# cat /usr/local/php-fpm/etc/php-fpm.d/www.conf

listen = /tmp/www.sock

request_slowlog_timeout = 1
slowlog = /usr/local/php-fpm/var/log/www-slow.log
php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp/

pm = dynamic //動態進程管理，也可以是static,這時下面的配置不生效啓動就生成50個子進程不會改變
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
