目标绝对路径。如果 src 是一个目录， dest 也必须是一个目录。如果 dest 是不存在的路径，并且如果dest以 / 结尾或者src是目录，则dest被创建。如果 src 和 dest 是文件，如果 dest 的父目录不存在，任务将失败 follow yes / no 是否遵循目的机器中的文件系统链接 force yes / no 当内容不同于源时，将替换远程文件。设置为 no ，则只有在目标不存在的情况下才会传输文件 group 设置文件/目录的所属组，将被馈送到chown local_follow yes / no 是否遵循本地机器中的文件系统链接 设置文件权限，模式实际上是八进制数字（如0644），少了前面的零可能会有意想不到的结果。从版本1.8开始，可以将模式指定为符号模式（例如u+rwx或u=rw,g=r,o=r） owner 设置文件/目录的所属用户，将被馈送到chown remote_src(2.0+) yes / no 如果yes它会从目标机上搜索src文件 将本地路径复制到远程服务器; 可以是绝对路径或相对的。如果是一个目录，它将被递归地复制。如果路径以 / 结尾，则只有该目录下内容被复制到目的地，如果没有使用 / 来结尾，则包含目录在内的整个内容全部复制 unsafe_writes yes / no 是否以不安全的方式进行，可能导致数据损坏 validate 复制前是否检验需要复制目的地的路径

拷贝前备份

[root@centos7 ~]# ansible test -m copy -a "src=test.sh backup=yes dest=/root"

源目录以/结尾，只拷贝了目录下的内容：

只拷贝了目录下的内容
源目录未以/结尾，直接将src目录本身拷贝到目的地：
