常见问题
3.1.1 rsync服务端排错思路
查看rsync服务配置文件路径是否正确,正确的默认路径为:/etc/rsyncd.conf
查看配置文件里host allow,host deny,允许的IP网段是否是允许客户端访问的IP网段。
查看配置文件中path参数里的路径是否存在,权限是否正确(正常应为配置文件中的UID参数对应的属主和组)
查看rsync服务是否启动。查看命令为:ps -ef | grep rsync。端口是否存在netstat -plunt| grep 873
查看iptables防火墙和selinux是否开启允许rsync服务通过,也可考虑关闭。
查看服务端rsync配置的密码文件是否为600的权限,密码文件格式是否正确,正确格式用户名:密码,文件路径和配置文件里的secrect files参数对应。
如果是推送数据,要查看下,配置rsyncd.conf文件中用户是否对模块下目录有可读写的权限。
3.1.2 rsync客户端排错思路
查看客户端rsync配置的密码文件是否为600的权限,密码文件格式shfou 正确,注意:仅需要有密码,并且和服务端的mima 一直
用telnet链接rsync服务器IP地址873查看服务是否启动(可测试服务端防火墙是否阻挡)
客户端执行命令是rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup
此命令的细节要记清楚,尤其是双冒号
3.2 No route to host问题

[root@nfs01 ~]

解决方案
服务端关闭防火墙
3.3 执行命令错误导致的报错

rsync
error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
|
解决:
rsync命令语法理解错误:/backup 必须是模块,也就是不能“/”

[root@nfs01 ~]
|
解决:
1.账号rsync_backup或者密码123456错误了。
2.指定的密码文件和实际的名称不一致。
secrets file = /etc/rsync.password
3.密码文件的权限忘记改为600
4.密码文件多了一个空格。 vi时候用set list或者用cat -A

3.11 客户端目录权限644+rsync使用了avz参数
推送之后会给服务端的/backup目录修改权限。使服务端权限变成644导致传输失败。
sh [root@nfs01 ~]# echo 123456>/etc/rsync.password ash: 123456: Bad file descriptor
