cronify 0.13

安装

需要运行的Linux内核>；=2.6.13

$ sudo pip install cronify
$ sudo chmod +x /etc/init.d/cronifyd
# Install a /etc/cronify.yaml file as in the examples below
# Once a configuration file is in place, start the cronify daemon with the provided init script
$ sudo /etc/init.d/cronifyd start

配置示例

$ cat /etc/cronify.yaml

/tmp/testdir :name :Access log watcherrecurse :falsefilemasks :somefile.* :actions :-processFile :args:-$filename-YYYYMMDDcmd:echo

$ sudo /etc/init.d/cronifyd start
$ touch /tmp/testdir/somefile.txt
$ tail /var/log/cronify/cronify.log

cronify.cronify - Thread-1 - 2013-03-26 17:40:40,485 - INFO - Got result from action {'cmd': 'echo', 'args': ['echo', '/tmp/testdir/somefile.txt', '20130326']} - /tmp/testdir/somefile.txt 20130326

具有多个监视程序和延迟操作的更复杂配置

有关接受配置的完整列表，请参见存储库中的example.yaml

已知限制

• 重新启动服务时，当前排队的操作将丢失。

• 使用recurse时，inotify仅限于监视树中n个子目录，其中n是/proc/sys/fs/inotify/max_user_watches的值。见http://linux.die.net/man/7/inotify

  用户可以通过修改/proc/sys/fs/inotify/max_user_手表来增加此限制

• 当在nfs服务器端监视nfs目录时，inotify api只会看到nfs server生成的事件，然后是cronify本身。

  在nfs客户端监视nfs目录时，inotify根本看不到任何事件。

  换言之，如果您计划监视由nfs client创建的文件，则当前无法执行此操作。
