- 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.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
include = 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

listen = /tmp/php-fcgi.sock

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

pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35

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.conf
request_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
<?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

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.conf
php_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
