如何使用capistrano将文件复制到一堆服务器

标签: file copy capistrano

我使用cap调用很多来在一堆服务器上运行命令。我还想使用capistrano将单个文件推送到一堆服务器。

起初我认为PUT会这样做,但是put会让你为文件创建数据。我不想这样做,我只想将现有文件从我运行capistrano命令的机器复制到其他机器。

如果我能做这样的事情会很酷:

host1$ cap HOSTS=f1.foo.com,f2.foo.com,f3.foo.com COPY /tmp/bar.bin 

我希望这会将host1:/tmp/bar.bin复制到f1.foo.com:/tmp/bar.bin和f2.foo.com:/tmp/bar.bin和f3.foo.com: /tmp/bar.bin

这种事情似乎非常有用,所以我确信必须有办法做到这一点......

upload(from, to, options={}, &block)

上传操作将文件存储在当前任务所针对的所有服务器上的给定路径上。

如果之前曾使用过deploy:upload任务,那么您可能已经知道此方法的工作原理。它采用您要上载的资源的路径和远程服务器上的目标路径。

desc "Uploads CHANGELOG.txt to all remote servers."
task :upload_changelog do
  upload("#{RAILS_ROOT}/CHANGELOG.txt", "#{current_path}/public/CHANGELOG")
end

这会将所有文件上传到相应的服务器。

没有cap deploy:upload的任何来这里的人都可以尝试使用cap invoke来拉文件而不是推送文件。例如:

cap invoke COMMAND='scp host.where.file.is:/path/to/file/there /target/path/on/remote`
