rsync配置
为实现同步更新文件配置了下rsync
在redhat系统上配置 rsync-2.6.3-1
服务端相关配置

1.在/etc/下创建三个文件
rsyncd.conf     rsyncd.motd     rsyncd.secrets 
2.配置文件
vi rsyncd.conf
motd file = /etc/rsyncd.motd #欢迎文件
read only = no
list = yes
uid = root
gid = root
hosts allow = 192.168.128.133
hosts deny =192.168.128.0/24
max connections = 2
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsyncd.lock

#define dirctory for rsync
[test]
comment = nagios's directory from 192.168.128.133
path =/test
secrets file =/etc/rsyncd.secrets#密码文件
auth users = test #rsync用户（与linux里的用户无关）
read only = no

3.欢迎文件
[root@localhost test]# vi /etc/rsyncd.motd
Welcome to use the rsync services!

4.密码文件
[root@localhost test]#vi /etc/rsyncd.secrets
test:test

5.chmod 600 /etc/rsyncd.*
6.运行rsync
/usr/local/rsync/bin/rsync --daemon /etc/rsyncd.conf
rsync的路径 rsync配置文件

7.客户端相关配置
a)安装rsync包
b)创建密码文件
[root@localhost ~]#vi /etc/rsyncd.secrets  
test#客户端只需密码无须用户
c)chmod 600 /etc/rsyncd.secrets
如果没有这步会报
password file must not be other-accessible
continuing without password file
Password: 
d)rsync -vzrtopg --progress --delete --password-file=/etc/rsyncd.secrets [email protected]::test/root/test  
测试连接
8.实现定时同步

8.实现定时同步
crond.rsync
*/10 * * * * rsync -vzrtopg --progress --delete --password-file=/etc/[email protected]::test /root/test

crontab crond.rsync
crontab -e编辑现在有crontab
crontab -l
