php-fpm的pool
主要用来隔离各个站点，相互不影响。当某个网站出问题时，不影响到其他的站点。
增加池子配置，例如增加 test.com
[root@test-a etc]# cat php-fpm.conf

进程管理
- pm = dynamic ;动态进程管理，也可以是static
- 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。
