双台服务器rsync同步报错(code 5) at main.c(1503) [sender=3.0.6]

Posted 2020-10-06

环境：某某项目的代码机器70配置有双网卡：232.182.23.70（联通）61.10.45.70（电信）

另一台代码机器是沧州联通的代码机器102，配置单网卡：121.15.1.102（联通）

rsync服务端服务器121.15.1.102上的配置文件rsyncd.conf

一开始/etc/rsyncd.conf 里面配置的允许ip:为61.10.45.70

[[email protected] tmp]# cat /etc/rsyncd.conf 

##rsyncd.conf start##

uid = root

gid = root

port=873

use chroot = no 

read only = no 

list = no 

max connections = 200

timeout = 300

auth users = stuser

hosts allow =  61.10.45.70

#hosts deny = *

pid file = /var/run/rsyncd.pid

lock file = /var/run/rsync.lock

log file = /var/log/rsyncd.log

secrets file = /etc/rsync.pass

motd file = /etc/rsyncd.Motd

[sdkdhcode]

path = /data/www/sdkdhcode/

comment = sdkdhcode

看似一切正常，但是这样在配置好的rsync的同步环境就出问题了：

（61.10.45.70机器推送数据到121.15.1.102机器上）

[[email protected] tmp]# rsync -avH --port=873 --progress  /opt/biao-framedb_backup.sh  [email protected]::sdkdhcode --password-file=/tmp/lmpasswd.txt 

@ERROR: Unknown module ‘sdkdhcode‘

rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]

原因是：rsync在同步中两台服务器的网卡寻找线路是联通找联通，电信的找电信的，而上面个的配置文件中添加的是的电信的ip地址：61.10.45.70，这样会导致61.10.45.70机器进行rsync传顺数据包到121.15.1.102机器上出问题，

于是把上面的rsyncd.conf配置文件中的 地址改为112.82.223.70（联通ip）就没问题了

解决上面的问题是从报错日志文件中发现:

tail -100f /var/log/rsyncd.log
