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

Password:

方法三（not works）：

[root@slave-5 ~]# mkdir /home/hadoop/testrsync

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

Password:

rsync error: error starting client-server protocol (code 5) at main.c(1635) [Receiver=3.1.1]

方法四（not works）：重启下服务端试试

[root@master software]# ps -ef|grep rsync

root     31634 2714  0 18:20 pts/1    00:00:00 grep rsync

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
