One, PHP-FPM pool (configure multiple pools with multiple isolation sites)
#cd/usr/local/php-fpm/etc/
#vim php-fpm.conf//Add configuration file to the second site aming.com, [www] and [aming.com] in the configuration file are equivalent to two different pools
#/usr/local/php-fpm/sbin/php-fpm-t//Check for grammatical errors
#/etc/init.d/php-fpm Reload//restart
#ps aux |grep php-fpm//can view [www] and [aming.com] two different pools
#vim aaa.com.conf//Add the following sections so that two sites are separated from each other.
The benefit of defining multiple pools is that there is a problem with the code for a site, which causes the site to run out of resources, access to the 502 error, and the other site unaffected because they are using different pools
#cd/usr/local/php-fpm/etc/
#cat php-fpm.conf
#vim php-fpm.conf//Add a line of include, delete [www] and [aming.com] two pools
#mkdir/usr/local/php-fpm/etc/php-fpm.d///Create a php-fpm.d/directory
#cd/usr/local/php-fpm/etc/php-fpm.d/
#vim www.conf//Create a www.conf file in the php-fpm.d/directory and write this part of [www] in
#vim aming.conf//Create a aming.conf file, write the [aming.com] part of the content in
#/usr/local/php-fpm/sbin/php-fpm-t
#/etc/init.d/php-fpm Restart//Restart PHP-FPM
Second, php-fpm slow execution log
#vi www.conf//profiles are generally recommended to log for more than 2 seconds
#/usr/local/php-fpm/sbin/php-fpm-t
#/etc/init.d/php-fpm Reload
#ls/usr/local/php-fpm/var/log///Check the/usr/local/php-fpm/var/log/directory for Www-slow.log logs
Php-fpm.log Www-slow.log
#vim/data/wwwroot/test.com/sleep.php//In the/data/wwwroot/test.com/directory to create sleep.php, write the following content can also be written as a line without wrapping
Troubleshooting methods:
#vi/usr/local/php-fpm/etc/php.ini//Search for display_errors in the configuration file, change 466 lines display_errors = off to display_errors = ON, The benefit of this modification is that directly can be done on the page to see what the specific error is
#/etc/init.d/php-fpm Reload
#curl-x127.0.0.1:80 test.com/sleep.php//access under sleep.php
#cat/usr/local/php-fpm/var/log/www-slow.log//View the log will record the slow execution log
Third, Open_basedir
#cd/usr/local/php-fpm/etc/php-fpm.d/
#vi www.conf
Add php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp/in the last line, note that the path here is to write to, otherwise access
#/etc/init.d/php-fpm restart
#curl-x127.0.0.1:80 test.com/sleep.php//Access status code is 200
#vim/usr/local/php-fpm/etc/php.ini
On-line production environment, the status of Display_errors = off should be defined as off so that no one else can see your error message in the browser
; error_log = Php_errors.log
; Log errors to Syslog (Event Log on Windows).
; error_log = syslog
Error_log =/usr/local/php-fpm/var/log/php-errors.log//Add a row to define the error log path
error_reporting = E_all & ~e_deprecated & ~e_strict//Add a line below this line and comment out this line
Error_reporting =e_all//Add a new line
#grep Error_log/usr/local/php-fpm/etc/php.ini//Find the definition path for the error log
; Server-specific log, STDERR, or a location specified by the Error_log
; Set maximum length of log_errors. In Error_log information on the source is
; error_log = Php_errors.log
; error_log = syslog
Error_log =/usr/local/php-fpm/var/log/php-errors.log
; Opcache error_log file name. Empty string assumes "stderr".
; opcache.error_log=
#ls/usr/local/php-fpm/var/log///view no error log path defined in PHP.ini under this path
Php-fpm.log Www-slow.log
#touch/usr/local/php-fpm/var/log/php-errors.log//Manually create a Php-errors.log file
#chmod 777/usr/local/php-fpm/var/log/php-errors.lo//permissions 777, otherwise the error log cannot be written
#/etc/init.d/php-fpm Restart//restart
#curl-x127.0.0.1:80 test.com/sleep.php//access under sleep.php
#cat/usr/local/php-fpm/var/log/php-errors.log//View error log
Iv. PHP-FPM Process Management
#vim www.conf
[WWW]
Listen =/tmp/php-fcgi.sock
Listen.mode = 666
user = PHP-FPM
Group = PHP-FPM
PM = dynamic//Defines how the process is started (dynamic, static for statics) only the PM is set to dynamic and the following configuration takes effect
Pm.max_children = 50//Defines the maximum number of child processes to start
Pm.start_servers = 20//start of the number of child processes started, default start 20
Pm.min_spare_servers = 5//Idle at least 5 sub-processes, to 5 will automatically increase
Pm.max_spare_servers = 35//idle up to a few sub-processes, up to 35 will be self-tuning
Pm.max_requests = 500//The maximum number of requests per sub-process can be accepted, and the child process will automatically exit when 500 is reached
Rlimit_files = 1024//Number of file handles opened per child process
