51, php-fpm Pool, php-fpm slow execution log, Open_basedir, PHP-FPM process Management

First, the pool of PHP-FPM

Pool: Right. The right-most column of PS aux. It's the pond.

# CD/USR/LOCAL/PHP-FPM/ETC

# cat php-fpm.conf//supports defining multiple pools

[Global]

PID =/usr/local/php-fpm/var/run/php-fpm.pid

Error_log =/usr/local/php-fpm/var/log/php-fpm.log

[www]//This is a pool

Listen =/tmp/php-fcgi.sock

#listen = 127.0.0.1:9000

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

Each pool can listen for different sockets or TCP/IP.

If Nginx has several sites, each site can use a pool, the advantage is that when a certain php502 (502 is probably not enough PHP resources), if many sites are using the same pool, if a programmer wrote the wrong thing, It will run out of PHP resources so that other sites will be 502, so it is necessary to use a separate pool for each site.

PHP-FPM can continue to increase pool:

# VIM php-fpm.conf//Added a

[Mrx.com]

Listen =/tmp/mrx.sock

#listen = 127.0.0.1:9000

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

PHP-FPM 1541 0.0 0.2 227228 4704? S 22:11 0:00 Php-fpm:pool mrx.com

How to use:

# cd/usr/local/nginx/conf/vhost/

# Vim Test.com.conf

Location ~ \.php$

{

Include Fastcgi_params;

Fastcgi_pass Unix:/tmp/php-fcgi.sock; Set Php-fcgi.sock here

Fastcgi_index index.php;

Fastcgi_param Script_filename/data/wwwroot/test.com$fastcgi_script_name;

}

# Vim Aaa.com.conf

Location ~ \.php$//So two sites are separated from each other.

{

Include Fastcgi_params;

Fastcgi_pass unix:/tmp/Mrx.sock;

Fastcgi_index index.php;

Fastcgi_param script_filename/data/wwwroot/default$fastcgi _script_name;

}

If Test.com.conf has 50 requests, the request is full, then the request will be reported 502, because there is no extra PHP to provide it with services, and mrx.com this site is not affected, because it uses another pool.

# tail. /nginx.conf

Tcp_nodelay on;

gzip on;

Gzip_min_length 1k;

Gzip_buffers 4 8k;

Gzip_comp_level 5;

Gzip_http_version 1.1;

Gzip_types text/plain application/x-javascript text/css text/htm

include vhost/*.conf; There is this one in Nginx, PHP-FPM also supports

}

Error_log =/usr/local/php-fpm/var/log/php-fpm.log

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

Add a line to global.

and split the contents of the pool below. Copy and delete all of the following content first.

# mkdir PHP-FPM.D

[Email protected] etc]# CD php-fpm.d/

Because you just defined PHP-FPM.D, create a directory

[Email protected] php-fpm.d]# vim www.conf

[WWW]

Listen =/tmp/php-fcgi.sock

#listen = 127.0.0.1:9000

Gracefully shutting down php-fpm. Done

Again PS aux |grep php-fpm can see, is the same effect, mrx.com in front, www in the back.

Second, php-fpm slow execution log (very useful)

PHP Web site, the proposed use of LNMP, one of the reasons is that you can analyze the slow log of PHP, website slow can be performed by slow log analysis.

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

# Vim Www.conf

Request_slowlog_timeout = 1 //means record log for more than 1 seconds, generally set 2 seconds for

These two lines are added to the last side.

Slowlog =/usr/local/php-fpm/var/log/www-slow.log//path of the log

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

[Email protected] php-fpm.d]#/ETC/INIT.D/PHP-FPM Reload

Reload Service PHP-FPM Done

# ls/usr/local/php-fpm/var/log///Check logs have no build

Php-fpm.log Www-slow.log

Configure Nginx Virtual host test.com.conf, change Unix:/tmp/php-fcgi.sock to Unix:/tmp/www.sock, and reload Nginx service.

# vim/data/wwwroot/test.com/sleep.php

<?php

echo "Test slow Log";

Sleep (2);

echo "Done";

?>

# Vim/usr/local/php-fpm/etc/php.ini

Display_errors = on here to change the off to on the browser can see the error log, the line here to off, you can not let others in the browser to see your error message.

# curl-x127.0.0.1:80 test.com/sleep.php Test, it will be 2 seconds slower and then logged into the slow execution log.

# Cat/usr/local/php-fpm/var/log/www-slow.log

Sleep ()/data/wwwroot/test.com/sleep.php:3

This line indicates that the 3rd line of the file is slow. So if the website is slow, you can view this slow execution log slow.log.

Third, PHP-FPM definition Open_basedir

Previously defined in php.ini Open_basedir, if there are multiple sites on the server, it is not appropriate to define in php.ini. Open_basedir can be done for each pond.

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

php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp/Add this line configuration, when this line configuration is wrong, it will be 404, here is the correct test.com.

#/etc/init.d/php-fpm Restart

# curl-x127.0.0.1:80 Test.com/3.php-i The effect of writing a mistake.

http/1.1 404 Not Found

# curl-x127.0.0.1:80 Test.com/3.php-i the correct effect.

http/1.1 OK

# Vim/usr/local/php-fpm/etc/php.ini

Display_errors = off on change back off, the line here to OFF, you can not let others in the browser to see your error message.

Log_errors = On the correct way is to record the error message in a file on the server.

Error_log = syslog is defined below this line.

Error_log =/usr/local/php-fpm/var/log/php_errors.log A newly added line.

Error_reporting = E_all Defines the log level, all records.

# ls/usr/local/php-fpm/var/log/First check if there's php_errors.log this file

Php-fpm.log Www-slow.log

# Touch/usr/local/php-fpm/var/log/php_errors.log didn't touch a

# chmod 777/usr/local/php-fpm/var/log/php_errors.log permissions changed to 777 to prevent the normal write.

When www.com.conf write a mistake:

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

#/etc/init.d/php-fpm Restart

# Cat/usr/local/php-fpm/var/log/php_errors.log look at the error log

Iv. PHP-FPM Process Management

[email protected] php-fpm.d]# cat www.conf

[WWW]

Listen =/tmp/php-fcgi.sock

#listen = 127.0.0.1:9000

Listen.mode = 666

user = PHP-FPM

Group = PHP-FPM

PM = dynamic/Active process management, can be static (static), dynamic.

Pm.max_children = 50//maximum number of sub-processes, PS aux can be viewed. static when only this line takes effect, with static when the direct start is 50, so use dynamic.

Pm.start_servers = 20//Number of processes that will start when the service is started

Pm.min_spare_servers = 5//Defines the minimum number of child processes in the idle period, and if this value is reached, PHP-FPM automatically derives the new child process.

Pm.max_spare_servers = 35//Defines the maximum number of child processes in the idle period, or, if higher than this value, to start cleaning up idle child processes.

Pm.max_requests = 500//defines the maximum number of requests processed by the same child process, that is, at most one php-fpm child process can handle so many requests, when this value is reached, it automatically exits. If you do not quit this child process will always exist, in case there is a problem with this child process.

Rlimit_files = 1024

Request_slowlog_timeout = 1

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

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

# PS aux |grep mrx.com |wc-l

21 This is because mrx.com defines the number of processes that start at startup is 20, and if these processes are not used, these idle processes are destroyed, the limit is destroyed, and a minimum of 5 child processes are preserved.

# PS aux |grep php-fpm |wc-l

42

These parameters can be customized to their own needs.
