Password: 
@ERROR: auth failed on module www
rsync error: error starting client-server protocol (code 5) at main.c(1516) [Receiver=3.0.9]

rsync服务器配置如下

[root@localhost ~]# cat /etc/rsyncd.conf 
# /etc/rsyncd: configuration file for rsync daemon mode

# See rsyncd.conf man page for more options.

# configuration example:

uid = nobody
gid = nobody
use chroot = yes
max connections = 40
pid file = /var/run/rsyncd.pid
exclude = lost+found/
transfer logging = yes
log file = /var/log/rsyncd.log
timeout = 900
ignore nonreadable = yes
dont compress   = *.gz *.tgz *.zip *.z *.Z *.rpm *.deb *.bz2
address = 192.168.20.115
port = 873 
hosts allow = 192.168.20.0/24

[www]
        path = /var/www/html/
        comment = web file
        read only = yes
        auth users = backuper
        auth secrets = /etc/rsync.db

分析

指定秘钥的字段是secrets file 将其改过 重启服务即可

[root@localhost ~]# vim /etc/rsyncd.conf 
# See rsyncd.conf man page for more options.

# configuration example:

uid = nobody
gid = nobody
use chroot = yes
max connections = 40
pid file = /var/run/rsyncd.pid
exclude = lost+found/
transfer logging = yes
log file = /var/log/rsyncd.log
timeout = 900
ignore nonreadable = yes
dont compress   = *.gz *.tgz *.zip *.z *.Z *.rpm *.deb *.bz2
address = 192.168.20.115
port = 873
hosts allow = 192.168.20.0/24

[www]
        path = /var/www/html/
        comment = web file
        read only = yes
        auth users = backuper
        secrets file = /etc/rsync.db
