PHP-FPM pool, slow execution log, process management, Open_basedir

The pool of PHP-FPM

To avoid the pool problem caused by one site failure due to multiple sites using the same pool, and to affect the normal operation of other sites using the same pool, configure a separate pool for each site.

• Add Pool to PHP-FPM

To edit the PHP-FPM configuration file:
......
[Huang.com]
Listen =/tmp/huang.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
......
[Huang.com] Modified by the previous [www] pool.

• Configure a pool for a site

[Email protected] ~]# vim/usr/local/nginx/conf/vhost/aaa.com.conf
......
Location ~. php$
{
Include Fastcgi_params;
Fastcgi_pass Unix:/tmp/huang.sock;
Fastcgi_index index.php;
Fastcgi_param Script_filename/data/wwwroot/default$fastcgi_script_name;
}
Add the above parsing PHP configuration. Change the Fastcgi_pass address to PHP-FPM. The same address in Conf is available.

To add a php-fpm.conf child configuration file

For ease of administration, each pool in the PHP-FPM can be managed separately. Do the following to add the PHP-FPM child configuration file.

• Edit php-fpm.conf

[[email protected] ~]# 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//Add parameter in global variables section "include = Etc/php-fpm.d/*.conf ". You can then clear the other parameters in the PHP-FPM configuration file and set them separately under the PHP-FPM.D directory. Create PHP-FPM Sub-profile directory: [[email protected] ~]# MKDIR/USR/LOCAL/PHP-FPM/ETC/PHP-FPM.D Create Child profile [[email protected] ~]# Vim/usr/local/php-fpm/etc/php-fpm.d/www.conf[www]listen =/tmp/php-fcgi.socklisten.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//add above [[email protected] ~]# vim/usr/local/php-fpm/etc/php-fpm.d/huang.conf[ Huang.com]listen =/tmp/huang.socklisten.mode = 666user = Php-fpmgroup = PHP-FPMPM = Dynamicpm.max_children = 50pm.start_s ervers = 20pm.min_spare_servers = 5pm.max_spare_servers = 35pm.max_requests = 500rlimit_files = 1024//Add the above content detection configuration file, and Overload php-FPM service: [[email protected] ~]#/usr/local/php-fpm/sbin/php-fpm-t[09-jan-2018 23:18:55] notice:configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful[[email protected] ~]#/etc/init.d/php-fpm reloadReload Service PHP-FPM Done

Slow execution log for PHP-FPM

By php-fpm Slow log, we can clearly understand the PHP script where the execution time is long, it can be targeted to specific rows.

• Turn on slow execution log

Turn on slow execution log for [Www]pool:
[Email protected] ~]# 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, generally write for 2 seconds
Slowlog =/usr/local/php-fpm/var/log/www-slow.log
#日志存放地址
Add the above two lines of content

检测配置文件，重启php-fpm服务：[[email protected] ~]# /usr/local/php-fpm/sbin/php-fpm -t[09-Jan-2018 23:38:14] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful[[email protected] ~]# /etc/init.d/php-fpm reloadReload service php-fpm  done

To see if the slow execution log file is generated:
[Email protected] ~]# Ls/usr/local/php-fpm/var/log/www-slow.log
/usr/local/php-fpm/var/log/www-slow.log

• Test

  Add files using the [Www]pool site]

To create a test script file:
[Email protected] ~]# vim/data/wwwroot/test.com/sleep.php
<?php
echo "Test slow Log";
Sleep (2);
echo "Done";
?>

检测：[[email protected] ~]# curl -x127.0.0.1:80 test.com/sleep.phptest slow logdone查看慢执行日志：[09-Jan-2018 23:55:46]  [pool www] pid 2992script_filename = /data/wwwroot/test.com/sleep.php //提示哪个脚本慢[0x00007f86ce814090] sleep() /data/wwwroot/test.com/sleep.php:3//脚本的第几行慢//php网站访问慢，可以查看慢执行日志，排查慢的原因。

• After opening the php.ini file diplay_errors, you can view the specific error on the browser, this operation should not be used in the official on-line system!

Vim/usr/local/php-fpm/etc/php.ini
Change display_errors = Off to display_errors = On
/ETC/INIT.D/PHP-FPM Reload

执行命令时错误会直接输出在屏幕上。

PHP-FPM definition Open_basedir

Because if the server manages multiple Web sites, it is not appropriate to define multiple Open_basedir in php.ini, so it is either defined in the Apache virtual host configuration file or defined in the PHP-FPM configuration file. We can define the corresponding Open_basedir for different pools (pool).

• Configure Open_basedir

Configuration for the [WWW] pool
[Email protected] ~]# vim/usr/local/php-fpm/etc/php-fpm.d/www.conf
......
php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp/
......
Add the previous line configuration

重启php-fpm：[[email protected] ~]# /etc/init.d/php-fpm reloadReload service php-fpm  done

• Test

[Email protected] ~]# curl-x127.0.0.1:80 test.com/1.txt
Test Open_basedir

Note: If the OPEN_BASEDIR definition error, it will result in inaccessible, form a 404 status Code, output curl directly connected will prompt "No input file specified."

• Defining error logs

  Display_errors = off Normally, on-line This is OFF, others cannot see your error message through the browser, but instead log your error message to a file on the server

[Email protected] ~]# Vi/usr/local/php-fpm/etc/php.ini
......
Display_errors=off//Search display_errors to see if it is off, not the word change to off.

;error_log = syslogerror_log = /usr/local/php-fpm/var/log/php_error.log   //搜索error_log，在下面添加一行，定义错误日志路径。586行搜索error_reporting注释掉自带的error_reporting;error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICTerror_reporting = E_ALL  //定义错误日志的级别，所有 460行。......保存退出手动创建错误日志文件：[[email protected] ~]# touch /usr/local/php-fpm/var/log/php_error.log[[email protected] ~]# chmod 777 /usr/local/php-fpm/var/log/php_error.log//防止蹦年正常写入

• Test

  In order to facilitate testing, deliberately write the Open_basedir path in the/usr/local/php-fpm/etc/php-fpm.d/www.conf error, to facilitate testing

[Email protected] ~]# curl-x127.0.0.1:80 test.com/sleep.php-i
