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

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。

配置错误日志

配置记录php执行错误的日志

[root@localhost etc]# vim /usr/local/php-fpm/etc/php.ini
display_errors = Off
log_errors = On
error_log = /usr/local/php-fpm/var/log/php_error.log
;error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
error_reporting = E_ALL

# 再次将php的配置文件改错

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。
