php-fpm的pool

为了避免因多站点使用同一个pool时,如果一个站点访问量过大导致资源耗尽出现问题，进而影响使用同一个pool的其他站点的正常运行，就需要对每个站点配置一个单独的pool。实现方式和nginx的vhost差不多

编辑主配置文件

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

重建多个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 = 127.0.0.1:9000listen.mode = 666user = php-fpmgroup = php-fpmpm = dynamicpm.max_children = 50pm.start_servers = 20pm.min_spare_servers = 5pm.max_spare_servers = 35pm.max_requests = 500rlimit_files = 1024 ?[root@akuilinux01 php-fpm.d]# vim aming.conf[aming]listen = /tmp/aming.sock#listen = 127.0.0.1:9000listen.mode = 666user = php-fpmgroup = php-fpmpm = dynamicpm.max_children = 50pm.start_servers = 20pm.min_spare_servers = 5pm.max_spare_servers = 35pm.max_requests = 500rlimit_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[root@akuilinux01 php-fpm.d]# /etc/init.d/php-fpm restartGracefully shutting down php-fpm . doneStarting php-fpm ?done

PHP慢执行日志

配置文件中加入下面两行

[root@akuilinux01 ~]# vim /usr/local/php-fpm/etc/php-fpm.d/www.confrequest_slowlog_timeout = 1#当请求超过1秒开始记录日志slowlog = /usr/local/php-fpm/var/log/www-slow.log#日志存放地址

测试

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

open_basedir

当一台服务器跑多个站点时，可以使用openbasedir限定各个站点所能访问的服务器上的目录的范围，就需要每个pool设定open basedir

[root@akuilinux01 ~]# vim /usr/local/php-fpm/etc/php-fpm.d/www.confphp_admin_value[open_basedir]=/data/wwwroot/eetest.com:/tmp/#故意写错/data/wwwroot/eetest.com，正确是/data/wwwroot/test.com

进行测试

[root@akuilinux01 ~]# curl -x127.0.0.1:80 test.com/sleep.php -IHTTP/1.1 404 Not FoundServer: nginx/1.14.0Date: Tue, 19 Jun 2018 01:21:13 GMTContent-Type: text/html; charset=UTF-8Connection: keep-aliveX-Powered-By: PHP/5.6.30

再次更改www.conf，修改路径，再次测试

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

配置错误日志

[root@akuilinux01 ~]# vim /usr/local/php-fpm/etc/php.inierror_reporting = E_ALLdisplay_errors = Off;error_log = syslogerror_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 restartGracefully shutting down php-fpm . doneStarting php-fpm ?done

再次测试，测试前故意改错

[root@akuilinux01 ~]# vim /usr/local/php-fpm/etc/php-fpm.d/www.confphp_admin_value[open_basedir]=/data/wwwroot/eetest.com:/tmp/#故意写错/data/wwwroot/eetest.com，正确是/data/wwwroot/test.com

[root@akuilinux01 ~]# curl -x127.0.0.1:80 test.com/sleep.php -IHTTP/1.1 404 Not FoundServer: nginx/1.14.0Date: Tue, 19 Jun 2018 01:34:14 GMTContent-Type: text/html; charset=UTF-8Connection: keep-aliveX-Powered-By: PHP/5.6.30

pm.min_spare_servers = 5 //定义在空闲时段，子进程数的最少数量，如果达到这个数值时，php-fpm服务会自动派生新的子进程。
