12.21 php-fpm的pool 12.22 php-fpm慢执行日志 12.23 open_basedir 12.24 php-fpm进程管理

php-fpm的pool

cd /usr/local/php-fpm/etc/

vim /usr/local/php-fpm/etc/php-fpm.conf //在[global]部分增加

include = etc/php-fpm.d/*.conf

mkdir /usr/local/php-fpm/etc/php-fpm.d/

cd /usr/local/php-fpm/etc/php-fpm.d/

vim www.conf //内容如下

[www] listen = /tmp/www.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

继续编辑配置文件

vim aming.conf //内容如下

[aming.com] listen = /tmp/aming.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

/usr/local/php-fpm/sbin/php-fpm -t

/etc/init.d/php-fpm restart

ps aux |grep php-fpm

cd/usr/local/nginx/conf/vhost

vim aaa.com.conf

location ~ .php$ { include fastcgi_params; fastcgi_pass unix:/tmp/aming.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /data/wwwroot/default$fastcgi_script_name; }

php-fpm慢执行日志

vim /usr/local/php-fpm/etc/php-fpm.d/www.conf //加入如下内容

request_slowlog_timeout = 1

slowlog = /usr/local/php-fpm/var/log/www-slow.log

检测 /usr/local/php-fpm/sbin/php-fpm -t

加载 /etc/init.d/php-fpm reload

再查看一下日志有没有生成

ls/usr/local/php-fpm/var/log/

cat /usr/local/nginx/conf/vhost/test.com.conf

vi/usr/local/nginx/conf/vhost/test.com.conf

配置nginx的虚拟主机test.com.conf，把unix:/tmp/php-fcgi.sock改为unix:/tmp/www.sock;

重新加载nginx服务

/usr/local/nginx/sbin/nginx -t //检测是否有错误

/usr/local/nginx/sbin/nginx -s reload //重新加载

vim /data/wwwroot/test.com/sleep.php //写入如下内容

<?php

echo"test slow log";

sleep(2);

echo"done";

?>

如果想把错误直接显示在屏幕上，暂且不看日志。修改php.ini,设置如下：

vi /usr/local/php-fpm/etc/php.ini

display_errors = On

[root@localhost php-fpm.d]# curl -x127.0.0.1:80 test.com/sleep.php test slow logdo [root@localhost php-fpm.d]# cat /usr/local/php-fpm/var/log/www-slow.log [04-Jan-2018 23:12:04] [pool www] pid 5353 script_filename = /data/wwwroot/test.com/sleep.php [0x00007ffb01545298] sleep() /data/wwwroot/test.com/sleep.php:3

php-fpm定义open_basedir

open_basedir 的作用是限制php在指定的目录里活动。

vim /usr/local/php-fpm/etc/php-fpm.d/www.conf//加入如下内容

php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp/

进行测试 curl -x127.0.0.1:80 test.com/3.php -I

配置错误日志

vi /usr/local/php-fpm/etc/php.ini

display_errors = Off

error_log=/usr/local/php-fpm/var/log/php_errors.log

error_reporting = E_ALL

grep error_log/usr/local/php-fpm/etc/php.ini

ls/usr/local/php-fpm/var/log/

touch/usr/local/php-fpm/var/log/php_errors.log

chmod 777/usr/local/php-fpm/var/log/php_errors.log //防止不能正常写入

/etc/init.d/php-fpm restart //重启

再次测试 curl -x127.0.0.1:80 test.com/3.php -I

查看错误日志 cat/usr/local/php-fpm/var/log/php_errors.log

php-fpm进程管理

pm = dynamic //动态进程管理，也可以是static

pm.max_children = 50 //最大子进程数，ps aux可以查看

pm.start_servers = 20 //启动服务时会启动的进程数

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。

pm.max_spare_servers = 35 //定义在空闲时段，子进程数的最大值，如果高于这个数值就开始清理空闲的子进程。

pm.max_requests = 500 //定义一个子进程最多处理的请求数，也就是说在一个php-fpm的子进程最多可以处理这么多请求，当达到这个数值时，它会自动退出。
