安装rsync

#yum install rsync

# yum -y install xinetd

# vi /etc/xinetd.d/rsync

将如下代码

service rsync

{

disable = yes

socket_type = stream

wait = no

user = root

server = /usr/bin/rsync

server_args = –daemon

log_on_failure += USERID

}

中的 disable = yes 改成 disable = no

然后启动 xinetd

# /etc/init.d/xinetd start 或 service xinetd restart

注意:如果服务器上装有防火墙记得要打开端口,默认端口是873

# vi /etc/rsyncd.conf (这个文件如果不存在自己创建)

uid = root

gid = root

use chroot = no

max connections = 5

secrets file = /etc/rsyncd.secrets    rsyncd.pass        

log file = /var/log/rsyncd.log

pid file = /var/run/rsyncd.pid

lock file = /var/run/rsync.lock

commen= hello world

[web]

path = /user/web/webroot   /usr/wenjian/web   /home/data/htdocs   注这个是要同步的目录

auth users = rsync 用户名

read only = no

hosts allow = 192.168.1.182

hosts deny = *

list = true

ignore errors

[root@dianxin149 webserver]# vim /etc/server.pas    rsyncd.pass              

rsync149:tongBu   tongbu          

给文件正确的权限

# chown root:root /etc/server.pas

# chmod 600 /etc/server.pas   #(必须是600)

#service xinetd restart

#chkconfig xinetd on

镜像备份到dianxin182上的/mydata/bak目录下

电信182上的设置如下

tar xvzf rsync-2.6.7.tar.gz
cd rsync-2.6.7
./configure --prefix=/usr/local/rsync
make
make install

#vim /etc/server.pas

tongBu

# chown root:root /etc/server.pas

# chmod 600 /etc/server.pas

#crontable -e

* * * * * /user/rsync/bin/rsync 这是在客户端的路径 -avz --progress --password-file=/etc/rsyncd.secrets rsync@192.168.1.226::149182 /mydata/bak/ >/dev/null

# which rsync 查看rsync 安装路径

# vim /etc/rc.local

/user/rsync/bin/rsync –daemon

# echo "* * * * * /user/rsync/bin/rsync -avz --progress --password-file=/etc/rsyncd.secrets rsync@192.168.1.226::149182 /mydata/bak/ >/dev/null" >> /var/spool/cron/root

测试 在被同步端 rsync -vzrtopg --progress --delete --password-file=/etc/rsyncd.pass.pass rsync@192.168.X.X::web /usr/wenjian

4. 使用 --execlude= 排除不需要同步的文件后缀名

rsync -vzrtopg --progress --delete --password-file=/etc/rsync_client.pass --exclude="*.tmp" backup@192.168.1.2::web /opt/web

1)备份本地

rsync -r --progress --delete /root/test /root/test1

5. 使用 --execlude-from= 排除不需要同步的目录

[root@ASB opt]# rsync -vzrtopg --progress --delete --password-file=/etc/rsync_client.pass --exclude-from=/opt/pcdir backup@192.168.1.2::web /opt/web

如果出现错误

@ERROR: auth failed on module web1

rsync error: error starting client-server protocol (code 5) at main.c(1503) [receiver=3.0.6]

检查 用户名和密码在检查权限在检查secrets file = /etc/rsyncd.secrets etc后边的文件要对应
