安装
#第三方库
pip install pyinotify
#使用supervisor来守护进程
apt-get install supervisor
yum install supervisor使用
#安装完成后需要启动，按需要修改配置文件
supervisord -c /etc/supervisor/supervisord.conf
#配置文件例子
; supervisor config file
[unix_http_server]
file=/var/run/supervisor.sock ; (the path to the socket file)
chmod=0700 ; sockef file mode (default 0700)
[supervisord]
logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)
pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
childlogdir=/var/log/supervisor ; ('AUTO' child log dir, default $TEMP)
; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
[supervisorctl]
serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL for a unix socket
; The [include] section can just contain the "files" setting. This
; setting can list multiple files (separated by whitespace or
; newlines). It can also contain wildcards. The filenames are
; interpreted as relative to this file. Included files *cannot*
; include files themselves.
[include]
files = /data/vscode/watchfile/watchfile.conf #修改自己的配置文件地址
由于调用了河马扫描程序来检测文件，所以大量文件同时变更时，检测会慢，建议系统做大量变更时可以停掉程序。运行测试
在config.ini 中修改自己的配置，因为使用多线程来监控多目录，建议使用多目录配置
运行 python3 daemon.py来查看输出和测试邮件
异常处理
查看输出日志的时候，如果出现wd=-1
需要修改 vim /etc/sysctl.conf
fs.inotify.max_user_watches = 128000 #决定了同时同一用户可以监控的目录数量
日志中看到Event Queue Overflow
max_queued_events太小需要调整参数
