Question

我们有位于/opt/tomcat7.0的tomcat服务器我想只将logs目录同步到远程服务器，我正在尝试关注rsync命令并排除*所有内容并包含{ {1}}但它不会同步任何内容。

以下是tomcat目录（我只想同步logs目录）

logs

这里是rsync命令

[rsync@server1]$ ls /opt/tomcat7.0
bin/  conf/  lib/  logs/  temp/  webapps/  work/

我做错了什么？

Answer 1

任何不做的理由：

rsync -avz --delete --copy-links server1:/opt/tomcat7.0/logs /path/to/destination/.

Answer 2

该联机帮助页解释了为什么这不起作用以及如何使其工作：

   Note that, when using the --recursive (-r) option (which is implied by -a), every subcomponent of  every  path
   is  visited from the top down, so include/exclude patterns get applied recursively to each subcomponent's full
   name (e.g. to include "/foo/bar/baz" the subcomponents "/foo" and  "/foo/bar"  must  not  be  excluded).   The
   exclude  patterns actually short-circuit the directory traversal stage when rsync finds the files to send.  If
   a pattern excludes a particular parent directory, it can render a deeper include pattern  ineffectual  because
   rsync  did  not  descend  through that excluded section of the hierarchy.  This is particularly important when
   using a trailing '*' rule.  For instance, this won't work:

          + /some/path/this-file-will-not-be-found
          + /file-is-included
          - *

   This fails because the parent directory "some" is excluded by the '*' rule, so rsync never visits any  of  the
   files  in  the "some" or "some/path" directories.  One solution is to ask for all directories in the hierarchy
   to be included by using a single rule: "+ */" (put it somewhere before the "- *" rule), and  perhaps  use  the
   --prune-empty-dirs  option.   Another  solution  is to add specific include rules for all the parent dirs that
   need to be visited.  For instance, this set of rules works fine:

          + /some/
          + /some/path/
          + /some/path/this-file-is-found
          + /file-also-included
          - *
