php-fpm的pool

编辑php-fpm的配置文件

vim /usr/local/php-fpm/etc/php-fpm.conf

增加

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

删除

[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

创建目录

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

创建pool文件

cd /usr/local/php-fpm/etc/php-fpm.d/
vim www.conf

增加

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

vim shu32.conf
增加

[shu32]
listen = /tmp/shu32.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

在web虚拟文件设置sock

test.com中设置默认sock

vim /usr/local/nginx/conf/vhost/test.com.conf
##解析php##
    location ~ \.php$
        {
            include fastcgi_params;
            fastcgi_pass unix:/tmp/php-fcgi.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /data/wwwroot/test.com$fastcgi_script_name;
        }

aaa.com.conf设置sock为shu32.sock

vim /usr/local/nginx/conf/vhost/aaa.com.conf
##解析php##
    location ~ \.php$
        {
            include fastcgi_params;
            fastcgi_pass unix:/tmp/shu32.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /data/wwwroot/default$fastcgi_script_name;
        }

检测与生效

php-fpm与nginx都要检测生效

/usr/local/php-fpm/sbin/php-fpm -t
/etc/init.d/php-fpm reload
/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx -s reload

测试

aaa与test分别使用www与shu32

ps aux |grep php-fpm

php-fpm 网站慢执行日志

编辑php-fpm分开的配置文件

vim /usr/local/php-fpm/etc/php-fpm.d/www.conf

增加

request_slowlog_timeout = 1
slowlog = /usr/local/php-fpm/var/log/www-slow.log

检测与生效

/usr/local/php-fpm/sbin/php-fpm -t
/etc/init.d/php-fpm reload

创建测试文件

让web停顿两秒时间

vim /data/wwwroot/test.com/sleep.php
<?php
echo "test slow log";
sleep(2);
echo "done";
?>

测试

curl -x127.0.0.1:80 test.com/sleep.php

访问有两秒时间才结束

查看日志

提示访问test.com/sleep.php慢的原因在代码第三行

cat /usr/local/php-fpm/var/log/www-slow.log


[20-Mar-2018 00:57:28]  [pool www] pid 2469
script_filename = /data/wwwroot/test.com/sleep.php
[0x00007fb91fc38298] 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。

编辑php-fpm配置文件

vim /usr/local/php-fpm/etc/php-fpm.d/www.conf

添加如下代码

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

检测生效

/usr/local/php-fpm/sbin/php-fpm -t
/etc/init.d/php-fpm reload

使用curl测试

成功200
curl -x127.0.0.1:80 test.com/admin.php -I

HTTP/1.1 200 OK
Server: nginx/1.12.2
Date: Mon, 19 Mar 2018 17:24:44 GMT
Content-Type: text/html; charset=UTF-8
Connection: keep-alive
X-Powered-By: PHP/5.6.30

配置错误目录

将test.com改为wwtest.com

vim /usr/local/php-fpm/etc/php-fpm.d/www.conf
php_admin_value[open_basedir]=/data/wwwroot/wwtest.com:/tmp/

检测生效

/usr/local/php-fpm/sbin/php-fpm -t
/etc/init.d/php-fpm reload

使用curl测试

curl -x127.0.0.1:80 test.com/admin.php -I

HTTP/1.1 404 Not Found
Server: nginx/1.12.2
Date: Mon, 19 Mar 2018 17:18:53 GMT
Content-Type: text/html; charset=UTF-8
Connection: keep-alive
X-Powered-By: PHP/5.6.30

php错误日志设置

编辑php-fpm配置php.ini

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

log_errors = On  //开启错误日志记录
error_log = /usr/local/php-fpm/var/log/php_errors.log    //指定错误日志目录
error_reporting = E_ALL        //设置错误级别

创建日志文件

touch /usr/local/php-fpm/var/log/php_errors.log 
chmod 777 /usr/local/php-fpm/var/log/php_errors.log

检测生效

/usr/local/php-fpm/sbin/php-fpm -t
/etc/init.d/php-fpm reload

查看日志

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

php-fpm进程管理

cat /usr/local/php-fpm/etc/php-fpm.d/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/wtest.com:/tmp/

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。
