php-fpm的pool

Nginx可以配置多个主机，php-fpm也可以配置多个pool
配置多个pool可以隔离开各个网站，例如一个网站有问题，把PHP资源耗尽了，那其他网站和这个网站使用的是同一个pool 那也会受到影响，所以我们可以给每个站点都配置一个pool。网站报错502一般和PHP有关。

给不同的站点分别配置不同的pool

给两个站点分别配置不同的pool

配置拆分多个pool

在nginx.conf这个配置文件下有一行配置文件为 include vhost/*.conf; 他的作用为识别指定目录下以conf为结尾的配置文件，让每个站点为一个配置文件。

php-fpm查看慢执行日志

通过配置慢执行日志，可以让我们清晰的了解到PHP脚本在哪里执行时间长，可以定位到哪一行。

  1. /添加两行配置文件
  2. [root@lnmp php-fpm.d]# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf 
  3. request_slowlog_timeout = 1
  4. slowlog = /usr/local/php-fpm/var/log/www-slow.log
  6. [root@lnmp php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t
  7. [07-Sep-2021 08:32:31] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf 
  8. test is successful
  10. [root@lnmp php-fpm.d]# vim /usr/local/nginx/conf/vhost/test.com.conf 
  12. server
  13. {
  14.     listen 80;
  15.     server_name test.com;
  16.     index index.html index.htm index.php;
  17.     root /data/nginx/test.com;
  18.     location ~ \.php$ {
  19.         include fastcgi_params;
  20.         fastcgi_pass unix:/tmp/php-fcgi.sock;
  21.         fastcgi_index index.php;
  22.         fastcgi_param SCRIPT_FILENAME /data/nginx/test.com$fastcgi_script_name;
  23.     }
  24. }
  26. /重载PHP服务
  27. [root@lnmp php-fpm.d]# /etc/init.d/php-fpm reload
  28. Reload service php-fpm  done
  30. /可以看到我们配置的路径已经多了一个
  31. [root@lnmp php-fpm.d]# ls /usr/local/php-fpm/var/log/
  32. php-fpm.log  www-slow.log
  34. /现在的www-slow.log还是一个空文件。只会记录执行时间大于1s的日志
  35. [root@lnmp php-fpm.d]# cat /usr/local/php-fpm/var/log/www-slow.log

测试 写一个慢执行文件

  1. [root@lnmp php-fpm.d]# vim  /data/nginx/test.com/sleep.php
  2. <?php
  3. echo "test slow log";
  4. sleep(2);
  5. echo "done";
  6. ?>
  9. 执行这个脚本的时候可以明显看到慢了一下。
  10. [root@lnmp php-fpm.d]# curl -x127.0.0.1:80 test.com/sleep.php
  11. test slow logdone[root@lnmp php-fpm.d]# 
  12. 可以看到日志多出一行。说哪个文件，第三行 sellp（）问题。
  13. [root@lnmp php-fpm.d]# cat /usr/local/php-fpm/var/log/www-slow.log 
  15. [07-Sep-2021 10:55:16]  [pool 123.com] pid 30879
  16. script_filename = /data/nginx/test.com/sleep.php
  17. [0x00007fdbdc54d270] sleep() /data/nginx/test.com/sleep.php:3

php-fpm定义open_basedir

open_basedir目的就是安全，httpd可以针对每个虚拟机设置一个open_basedir
php-fpm同样也可以对不同的pool设置的不同的open_basedir

  1. 修改配置文件，特意配置为错误路径
  2. 添加一行配置文件，其中test.com的路径为错误路径
  3. [root@lnmp php-fpm.d]# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf 
  4. php_admin_value[open_basedir]=/data/nginx/wwwtest.com:/tmp/
  5. [root@lnmp php-fpm.d]# /etc/init.d/php-fpm restart
  6. Gracefully shutting down php-fpm . done
  7. Starting php-fpm  done
  9. /测试发现这些PHP文件都无法访问，就是因为php open_basedir做了限制。
  10. [root@lnmp php-fpm.d]# ls /data/nginx/test.com/
  11. 1.js  1.jss  2.jpg  2.js  3.php  admin  index.html  sleep.php
  12. [root@lnmp php-fpm.d]# curl -x127.0.0.1:80 test.com/sleep.php -I
  13. HTTP/1.1 404 Not Found

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

配置错误日志

配置记录php执行错误的日志

  1. 配置 
  3. [root@lnmp php-fpm.d]# vim /usr/local/php-fpm/etc/php.ini 
  4. display_errors = Off
  5. log_errors = On
  6. error_log = /usr/local/php-fpm/var/log/php_error.log
  7. ;error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
  8. error_reporting = E_ALL
  10. 再次将php的配置文件改错
  11. [root@lnmp php-fpm.d]# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf 
  12. php_admin_value[open_basedir]=/data/nginx/wwwtest.com:/tmp/
  14. 这个日志文件不会自动生成，所以我们自己创建一个，并授权。
  15. [root@lnmp php-fpm.d]# touch /usr/local/php-fpm/var/log/php_error.log
  16. [root@lnmp php-fpm.d]# chmod 777 /usr/local/php-fpm/var/log/php_error.log 
  17. [root@lnmp php-fpm.d]# /etc/init.d/php-fpm restart
  18. [root@lnmp php-fpm.d]# curl -x127.0.0.1:80 test.com/3.php -I
  19. HTTP/1.1 404 Not Found

  35. No input file specified.
  37. 查看错误日志，显示open_basedir限制生效，目录不能访问
  38. [root@lnmp php-fpm.d]# cat /usr/local/php-fpm/var/log/php_error.log

php-fpm进程管理

pm = dynamic //动态进程管理，也可以是static 如果是静态的，会直接启动最大子进程数
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。
