问题一：

rsync: chgrp "/data/www/vhosts/go/.rest.qXYFW5" (in apache) failed: Operation not permitted (1)

sent 6512253 bytes received 27 bytes 4341520.00 bytes/sec
total size is 13713300 speedup is 2.11
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1039) [sender=3.0.6]

解决方案：

rsyncd.conf文件设置成

uid = root
gid = root
