PHP-FPM Configuration

First, the pool of PHP-FPM

The PHP-FPM configuration file php-fpm.conf can be set to multiple pool, where one pool resource is exhausted, causing other sites to be unable to access resources, reporting a 502 error. It is necessary to separate the sites, using separate pool respectively.

1. Modify the configuration file

pear.conf  php-fpm.conf  php-fpm.conf.default  php.ini[[email protected] etc]# vim php-fpm.confinclude = etc/php-fpm.d/*.conf[global]#定义全局参数pid = /usr/local/php-fpm/var/run/php-fpm.piderror_log = /usr/local/php-fpm/var/log/php-fpm.log#添加上面这行，暂时注释掉下面的pool#[www]#listen = /tmp/php-fcgi.sock#监听地址，也可以写：listen = 127.0.0.1:9000，本地监听，也可以监听其他IP：port#此处格式会影响配置Nginx和PHP结合时Nginx寻址PHP的路径#listen.mode = 666#当监听的为socket文件时该部分才生效，用于指定.sock文件的权限#user = php-fpm#group = php-fpm#定义php-fpm服务的用户#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#以上部分为进程相关信息

2. Create a profile directory and sub-configuration file

[[email protected] etc]# mkdir/usr/local/php-fpm/etc/php-fpm.d[[email protected] etc]# CD php-fpm.d[[ Email protected] php-fpm.d]# ls[[email protected] php-fpm.d]# vim www.conf//new configuration file write to the following [Www]listen =/ tmp/www.sock# listening address, can also write: listen = 127.0.0.1:9000, local monitoring, can also listen to other ip:port# here format will affect the configuration nginx and PHP when the Nginx address PHP path Listen.mode = 666# This section takes effect when listening to a socket file, specifying the permissions for the. sock file user = Php-fpmgroup = php-fpm# Defines the user of the PHP-FPM service pm = Dynamicpm.max_children = 50pm.start_servers = 20pm.min_spare_servers = 5pm.max_spare_servers = 35pm.max_requests = 500rlimit_files = 1024# The above section is process-related information [[email protected] php-fpm.d]# vim zlinu.conf//In creating another profile, write the following [Zlinux]listen =/tmp/zlinux.s ock# listening address, can also write: listen = 127.0.0.1:9000, local monitoring, can also listen to other ip:port# here format will affect the configuration nginx and PHP when the Nginx address php path Listen.mode = 666# This section takes effect when listening to a socket file, specifying the permissions for the. sock file. user = Php-fpmgroup = php-fpm# defines the PHP-FPM service for users pm = Dynamicpm.max_children = 50pm.start_servers = 20pm.min_spare_servers = 5pm.max_spare_servers = 35pm.max_requeSTS = 500rlimit_files = 1024# The above part is process-related information 

3. Verify the configuration

4. Modify the virtual host configuration file to configure the pool for the site

[[email protected] php-fpm.d]# cd /usr/local/nginx/conf/vhost[[email protected] vhost]# vim zlinux.confserver{   listen 80 default_server;#  有default_server标记的就是默认虚拟主机   server_name zlinuxtest.com;   index index.html index.htm index.php;   root /data/wwwroot/zlinux; location ~ \.php$        {            include fastcgi_params;            # 这里写对应php-fpm.conf内设置的sock            fastcgi_pass unix:/tmp/zlinux.sock;            fastcgi_index index.php;             fastcgi_param SCRIPT_FILENAME /data/wwwroot/zlinux$fastcgi_script_name;         }}[[email protected] vhost]# /usr/local/nginx/sbin/nginx -tnginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

The above sets the pool separately, which is saved separately in the folder. You can also pool-fpm.conf add multiple pool directly in, and the site calls the corresponding row.

Second, php-fpm slow execution log 1, edit the configuration file

[[email protected] vhost]# vim /usr/local/php-fpm/etc/php-fpm.d/zlinu.conf [zlinux]listen = /tmp/zlinux.sock#监听地址，也可以写：listen = 127.0.0.1:9000，本地监听，也可以监听其他IP：port#此处格式会影响配置Nginx和PHP结合时Nginx寻址PHP的路径listen.mode = 666#当监听的为socket文件时该部分才生效，用于指定.sock文件的权限user = php-fpmgroup = php-fpm#定义php-fpm服务的用户pm = dynamicpm.max_children = 50pm.start_servers = 20pm.min_spare_servers = 5pm.max_spare_servers = 35pm.max_requests = 500rlimit_files = 1024#以上部分为进程相关信息request_slowlog_timeout = 1#当请求超过1秒开始记录日志slowlog = /usr/local/php-fpm/var/log/zlinux-slow.log#日志存放地址[[email protected] vhost]# /usr/local/php-fpm/sbin/php-fpm -t[19-Mar-2018 18:30:23] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful[[email protected] vhost]# /etc/init.d/php-fpm restartGracefully shutting down php-fpm . doneStarting php-fpm  done

2, Test slow log

[[email protected] vhost]# touch /usr/local/php-fpm/var/log/zlinux-slow.log[[email protected] vhost]# chmod 777 /usr/local/php-fpm/var/log/zlinux-slow.log[[email protected] vhost]# echo ‘<?php echo "slowlog test!"; sleep(2);echo "done"; ?>‘ > /data/wwwroot/zlinux/sleep.php[[email protected] php-fpm.d]# curl -x127.0.0.1:80 zlinux.com/sleep.phpslowlog test!done[[email protected] php-fpm.d]# [[email protected] php-fpm.d]# cat /usr/local/php-fpm/var/log/zlinux-slow.log     //查看蛮日志[19-Mar-2018 19:48:08]  [pool zlinux] pid 2354script_filename = /data/wwwroot/zlinux/sleep.php[0x00007f8f0c1802e8] sleep() /data/wwwroot/zlinux/sleep.php:3[19-Mar-2018 19:53:29]  [pool zlinux] pid 2356script_filename = /data/wwwroot/zlinux/sleep.php[0x00007f8f0c1802e8] sleep() /data/wwwroot/zlinux/sleep.php:3

Third, PHP-FPHP-FPM definition Open_basedir

When a server runs multiple sites, use Openbasedir to limit the range of directories on the servers that each site can access. In the PHP-FPM service, open Basedir can be set for each pool.

[[email protected] php-fpm.d]# vim /usr/local/php-fpm/etc/php-fpm.d/zlinux.conf   //加入如下内容php_admin_value[open_basedir]=/data/wwwroot/zlinux:/tmp/

Iv. PHP-FPM Process Management

PM = dynamic
Dynamic process management can also be static
; The following configuration will only take effect if this is set to dynamic
Pm.max_children = 50
Maximum number of sub-processes, PS aux can be viewed
Pm.start_servers = 20
: The number of processes that will start when the service is started
Pm.min_spare_servers = 5
To define the idle time period, the minimum number of child processes, if this value is reached, the PHP-FPM
The service automatically derives new child processes.
Pm.max_spare_servers = 35
Define the maximum value of the child process during the idle period, and start cleaning up the idle child process if it is above this value.
Pm.max_requests = 500
; Defines the maximum number of requests a child process can handle, meaning that a php-fpm child process is able to handle the request at most, and when that value is reached, he automatically exits.
