php-fpm定义open_basedir

# 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。

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。
