同步epel不成功

同步epel不成功，

使用https地址时提示如下

ssh: Could not resolve hostname https: Name or service not known rsync: connection unexpectedly closed (0 bytes received so far) [Receiver] rsync error: unexplained error (code 255) at io.c(226) [Receiver=3.1.2]

使用rsync地址是脚本无反应，中止脚本后提示如下 rsync error: received SIGINT, SIGTERM, or SIGHUP (code 20) at rsync.c(638) [Receiver=3.1.2]

需要配置端口吗

命令如下： /usr/bin/rsync -avrt --delete --exclude=debug/ --exclude=isos/ --exclude=SRPMS/ --exclude=ppc/ --delete-excluded --ignore-errors --include=6/x86_64 --include=6.2017-11-07/x86_64 rsync://mirrors.aliyun.com/epel-archive/ /yum_kms/epel-archive/
