1.客户端的错误现象:No route to host
rsync服务端开启了iptables防火墙 rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup rsync: failed to connect to 172.16.1.41: No route to host (113) 解决办法: 关闭rsync服务端的防火墙服务(iptables)
2.ERROR: The remote path must start with a module name not a /
rsync客户端执行rsync命令错误: rsync -avz /etc/hosts rsync_backup@172.16.1.41::/backup ERROR: The remote path must start with a module name not a / 问题原因: rsync命令语法理解错误,::/backup是错误的语法,应该为::backup(rsync模块)
3.@ERROR: auth failed on module backup
rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup Password: @ERROR: auth failed on module backup 问题可能原因: a.密码输入错误; b.secrets file = /etc/rsync.password指定的密码文件和实际密码文件名称不一致; c./etc/rsync.password文件权限不是600; d.rsync_backup:123456密码配置文件后面注意不要有空格; e.rsync客户端密码文件中只输入密码信息即可,不要输入虚拟认证用户名称
4.Unknown module 'backup'
rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup @ERROR: Unknown module 'backup' 问题可能原因: a./etc/rsyncd.conf配置文件模块名称书写错误 b.配置文件中网段限制不对
5.Permission denied
rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup Password: sending incremental file list hosts rsync: mkstemp ".hosts.5z3AOA" (in backup) failed: Permission denied (13) 问题可能原因: a.共享目录的属主和属组不正确,不是rsync b.共享目录的权限不正确,不是755
6.chdir failed
rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup Password: @ERROR: chdir failed 问题可能原因: a.备份存储目录没有建立 b.建立的备份存储目录和配置文件定义不一致 /etc/init.d/xinetd restart 如果没有备份存储目录,xinetd服务都不能正确启动
7.invalid uid rsync
rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup Password: @ERROR: invalid uid rsync 问题原因: rsync服务对应rsync虚拟用户不存在了
8.客户端已经配置了密码文件,依然需要输入密码
rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup --password-file=/etc/rsync.password password file must not be other-accessible continuing without password file Password: 解决问题: rsync客户端的秘钥文件也必须是600权限
9.rsync客户端连接慢问题
错误日志输出 params.c:Parameter() - Ignoring badly formed line in configuration file: ignore errors name lookup failed for 172.16.1.31: Name or service not known connect from UNKNOWN (172.16.1.31) rsync to backup/ from rsync_backup@unknown (172.16.1.31) receiving file list sent 76 bytes received 83 bytes total size 349 正确日志输出 params.c:Parameter() - Ignoring badly formed line in configuration file: ignore errors connect from nfs02 (172.16.1.31) rsync to backup/ from rsync_backup@nfs02 (172.16.1.31) receiving file list sent 76 bytes received 83 bytes total size 349 解决方法: 需要在服务端这台机上上的/etc/hosts里面添加客户端机的ip和机器名 172.16.1.31 nfs01
10.rsync服务没有正确启动Connection refused (111)
rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup rsync: failed to connect to 172.16.1.41: Connection refused (111) 解决方法: rsync --daemon
11.port 22: Connection refused
环境:本地服务器集群内部传输利用远程ssh 报错 rsync /etc/hosts 172.16.1.31:/tmp ssh: connect to host 172.16.1.31 port 22: Connection refused 排错思路: ping 172.16.1.31 traceroute 172.16.1.31 netstat -lntup|grep 22 故障原因:ssh配置有问题 telnet 172.16.1.31 22 解决方法: vim /etc/ssh/sshd_config #Port 22 #AddressFamily any #ListenAddress 10.0.0.31 改为 0.0.0.0 #ListenAddress ::
12.--passwd-file=/etc/rsync.passwd: unknown option
rsync -az -P /root/ rsync_backup@172.16.1.41::backup --passwd-file=/etc/rsync.passwd rsync: --passwd-file=/etc/rsync.passwd: unknown option 故障原因:没有正确输入password文件名 正确做法:--password-file=/etc/rsync.password
13.使用Cacti监控Linux服务器网卡流量的配置方法:

注意:在“Data Query”中选择要监控的网卡,记得点那个圆圈...,
添加完成并且将它分类之后,需要等三五分钟才能看见,不要急,不要认为你没有添加成功..
