前面已经看了不少样本,下面看看配置文件
inotify 相关的几个系统参数
/proc/sys/fs/inotify/max_user_instances 初始化 ifd 的数量限制
/proc/sys/fs/inotify/max_queued_events ifd 文件队列长度限制
/proc/sys/fs/inotify/max_user_watches 注册监听目录的数量限制
文件描述符,受 /etc/security/limits.conf 和 /proc/sys/fs/file-max 限制
默认值:
/proc/sys/fs/inotify/max_user_instances 16384
/proc/sys/fs/inotify/max_queued_events 128
/proc/sys/fs/inotify/max_user_watches 65536
/proc/sys/fs/file-max 6815744
