执行rsync出现如下错误：
rsync: writefd_unbuffered failed to write 4 bytes to socket [sender]: Connection reset by peer (104)
ERROR: module is read only
rsync error: syntax or usage error (code 1) at main.c(866) [receiver=3.0.6]
rsync: connection unexpectedly closed (5 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(600) [sender=3.0.6]
关键的错误信息是：ERROR: module is read only
解决方法：在rsync.conf文件中加入read only=no。
