本文详细描述了如何在Linux环境下解决Rsync软件版本冲突及配置错误导致的同步失败问题，包括卸载旧版本、更新客户端、修复配置文件、重启服务等步骤，并最终通过排查日志发现并解决了配置中不正确的`scretsfile`参数导致的权限验证失败，成功实现了跨主机文件同步。

首先下载对应linux的rsync软件： http://rsync.samba.org/download.html
本例中，下载 rsync-3.1.1-1.el5.rfx.i386.rpm 22-Jun-2014 21:58 420K RHEL5 and CentOS-5 x86 32bit

服务端配置

从日志信息可以看出和本机已经安装的rsync-2.6.8-3.1.i386冲突了。需要先卸载该包。

在客户端slave-5测试同步

[root@slave-5 ~]# rsync -vzrtopg --progress --delete root@master::hadoop /home/hadoop/testrsync

Password:

@ERROR: auth failed on module hadoop

rsync error: error starting client-server protocol (code 5) at main.c(1296) [receiver=2.6.8]

可见由于用户验证未通过，该操作失败了，下面用了几种方式进行调整并测试

方法一（not works）：

虽然该方法对本例未奏效，但是建议chmod 600 /home/hadoop/rsync.pass

[root@master software]# ll /home/hadoop/rsync.pass

-rwxrwxrwx 1 root root 13 Jul 21 17:23 /home/hadoop/rsync.pass

[root@master software]# chmod 600 /home/hadoop/rsync.pass

[root@master software]# ll /home/hadoop/rsync.pass

-rw-------1 root root 13 Jul 21 17:23 /home/hadoop/rsync.pass

[root@slave-5 ~]# rsync -vzrtopg --progress --delete root@master::hadoop /home/hadoop/testrsync

Password:

@ERROR: auth failed on module hadoop

rsync error: error starting client-server protocol (code 5) at main.c(1296) [receiver=2.6.8]

方法二（not works）：

在客户端更新跟服务器相同版本的rsync（后经测试，低版本的客户端也是能够正常从服务端同步文件的）

[root@slave-5 ~]# rpm -e rsync-2.6.8-3.1

[root@slave-5 software]# rpm -ivh rsync-3.1.1-1.el5.rfx.i386.rpm

方法五（works）：查看下服务器端的日志，终于发现问题在哪里了

[root@master rsync]# tail -f /var/log/rsyncd.log

在客户端再进行测试

[root@slave-5 selinux]#rsync -vzrtopg --progress --delete root@master::hadoop /home/hadoop/testrsync

在服务端观察下日志如下：

[root@master rsync]# tail -f /var/log/rsyncd.log
