rsync 通过密码文件实现远程同步

vim /etc/rsync.conf

uid = www
gid = www
read only = no
hosts allow = *
[web]
path = /var/www
auth users = yyp
secrets file = /etc/rsyncd.secrets

vim /etc/rsyncd.secrets
yyp:123456
chmod 600 /etc/rsyncd.secrets

useradd yyp
echo "123456" | passwd yyp --stdin

mkdir /var/wwww

启动服务
rsync --daemon --config=/etc/rsyc.conf

vim /etc/rsyncd.secrets
123456
chmod 600 /ec/rsyncd.secrets

mkdir /var/www

 同步文件
rsync -avz --password-file=/etc/rsyncd.secret /var/www yyp@192.168.10.88::web

错误汇总：
rsync: recv_generator: mkdir "test" (in dest) failed: Permission denied (13)
*** Skipping everything below this failed directory ***
这个表明权限不正确解决办法三个：（1）把备份服务器/etc/rsync.conf gid和uid 修改为root； （2）把备份目录上的权限设置为777；（3）修改备份目录拥有者和所属组为/etc/rsync.conf配置文件中的gid和uid

rsync: read error: Connection reset by peer (104)rsync error: error in rsync protocol data stream (code 12) at io.c(614) [receiver=2.6.8]
通过日志/var/log/messages查看得到
rsync: unable to open configuration file "/etc/rsync.conf": No such file or directory (2)
做一个软连接上去：ln -s /etc/rsyncd.conf /etc/rsync.con
