#服务端：192.168.15.127
1、创建配置文件
vim /etc/rsyncd.conf
pid file = /var/run/rsyncd.pid
log file = /var/log/rsyncd.log
read only = no
max connections = 50
use chroot = yes
[mysql]
hosts allow = 192.168.15.0/24
path=/tmp/
uid = root
gid = root
secrets file=/etc/rsyncd.passwd
read only = no
2、密钥文件/etc/rsyncd.passwd
echo "backup:123456" >>/etc/rsyncd.passwd
chmod 600 /etc/rsyncd.passwd
3、启动
rsyncd --daemon
#centos6.4
rsync --daemon
#客户端设置192.168.15.12
1、密钥设置
echo "123456" >>/etc/rsyncd.passwd
chmod 600 /etc/rsyncd.passwd
2、推送文件
rsync -vzrtopg /etc backup@192.168.15.127::mysql --password-file=rsyncd.passwd
3、拉文件
rsync -vzrtopg backup@192.168.15.127::mysql /tmp/ --password-file=rsyncd.passwd
***************************
排除故障
***************************
1.@ERROR: auth failed on module xxxxx
rsync: connection unexpectedly closed (90 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(150)
这是因为密码设错了, 无法登入成功, 请检查一下 rsyncd.scrt 中的密码, 二端是否一致?
2.password file must not be other-accessible
continuing without password file
Password:
这表示 rsyncd.scrt 的档案权限属性不对, 应设为 600。
3.@ERROR: chroot failed
rsync: connection unexpectedly closed (75 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(150)
这通常是您的 rsyncd.conf 中的 path 路径所设的那个目录并不存在所致.请先用 mkdir开设好要备份目录
4.@ERROR: access denied to www from unknown (192.168.1.123)
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(359)
最后原因终于找到了。因为有两个网段都需要同步该文件夹内容，但没有在hosts allow 后面添加另一个IP段
hosts allow = 192.168.1.0/24
改为
hosts allow = 192.168.1.0/24 192.168.2.0/24
重新启动rsync服务，问题解决
5.rsync: failed to connect to 172.21.50.8: No route to host (113)
rsync error: error in socket IO (code 10) at clientserver.c(104) [receiver=2.6.9]
对方没开机、防火墙阻挡、通过的网络上有防火墙阻挡，都有可能。关闭防火墙，其实就是把tcp udp 的873端口打开
启动服务：rsync --daemon --config=/etc/rsyncd.conf
6.@ERROR: auth failed on module backup
rsync error: error starting client-server protocol (code 5) at main.c(1506) [Receiver=3.0.7]
client端没有设置/etc/rsync.pas这个文件，而在使用rsync命令的时候，加了这个参数--password-file=/etc/rsync.scrt
7.rsync: recv_generator: mkdir "/teacherclubBackup/rsync……" failed: No space left on device (28)
*** Skipping any contents from this failed directory ***
磁盘空间满了
8.rsync: opendir "/kexue" (in dtsChannel) failed: Permission denied (13)
同步目录的权限设置不对，改为755
