echo "PATH=/usr/local/inotify/bin:$PATH" >>/etc/profile.d/inotify.sh

source /etc/profile.d/inotify.sh  #使设置立即生效

echo "/usr/local/inotify/lib" >/etc/ld.so.conf.d/inotify.conf

ln -s /usr/local/inotify/include  /usr/include/inotify

查看系统默认参数值

sysctl -a | grep max_queued_events

结果是：fs.inotify.max_queued_events = 

sysctl -a | grep max_user_watches

结果是：fs.inotify.max_user_watches = 

sysctl -a | grep max_user_instances

结果是：fs.inotify.max_user_instances = 

修改参数：

sysctl -w fs.inotify.max_queued_events=""

sysctl -w fs.inotify.max_user_watches=""

sysctl -w fs.inotify.max_user_instances=""

vi /etc/sysctl.conf #添加以下代码

fs.inotify.max_queued_events=

fs.inotify.max_user_watches=

fs.inotify.max_user_instances=
