rsync同步本地文件到服务器后文件权限变了

Question

根据rsync文档参数-a作用是同步后文件不改变属主和用户组，但是文件在本地是www:www同步到服务器老是变成mysql：mysql了，请问是哪里出了问题？

客户端同步动作：
rsync -avz --password-file=/root/rsync.pwd /home/wwwroot/* www@10.11.125.12::www_online

服务端rsync配置文件：
pid file = /tmp/rsync.pid
port = 873
address = 10.11.125.12
uid = root
gid = root
use chroot = yes
read only = no

hosts allow=10.163.37.136
hosts deny=*
max connections = 5

log file = /alidata/log/rsync/rsync.log
transfer logging = yes
log format = %t %a %m %f %b
syslog facility = local3
timeout = 300

[www_online]
path = /alidata/www/test
list=yes
ignore errors
auth users = www
secrets file = /etc/rsyncd/rsyncd.secrets

加个 -p 参数试试
