配置rsync 同步数据 rpm包安装rsync及配置

[root@Hammer home]# rpm -qa |grep rsync #检查系统是否安装了rsync软件包

rsync-2.6.8-3.1

[root@Hammer CentOS]# rpm -ivh rsync-2.6.8-3.1.i386.rpm # 如果没有安装则手动安装

[root@test rsync-3.0.4]# vim /etc/xinetd.d/rsync

1 配置rsync servervi /etc/xinetd.d/rsync

将disable=yes改为no

service rsync

{

disable = no

socket_type = stream

wait = no

user = root

server = /usr/bin/rsync

server_args = --daemon

log_on_failure += USERID

}

2 配置rsync自动启动

[root@test etc]# chkconfig rsync on

[root@test etc]# chkconfig rsync --list

rsync on

3 配置rsyncd.conf

[root@test etc]# vim rsyncd.conf

uid = root

gid = root

use chroot = no

max connections = 4

strict modes = yes

port = 873

pid file = /var/run/rsyncd.pid

lock file = /var/run/rsync.lock

log file = /var/log/rsyncd.log

[backup]

path = /srv

comment = This is test

auth users = scihoo

uid = root

gid = root

secrets file = /home/rsync.ps

read only = no

list = no

4 确保etc/services中rsync端口号正确

[root@test etc]# vim /etc/services

rsync 873/tcp # rsync

rsync 873/udp # rsync

5 配置rsync密码(在上边的配置文件中已经写好路径)/home/rsync.ps(名字随便写,只要和上边配置文件里的一致即可),格式(一行一个用户)

[root@test etc]# vi /home/rsync.ps

scihoo:scihoo

6 配置rsync密码文件权限

[root@test home]# chown root.root rsync.ps

[root@test home]# chmod 400 rsync.ps

7 启动配置

[root@test home]# /etc/init.d/xinetd restart

Stopping xinetd: [ OK ]

Starting xinetd: [ OK ]

8 如果xinetd没有的话,需要安装一下

[root@test home]# yum -y install xinetd

启动rsync server

(下载地址)https://pkgs.org/centos-5/centos-x86_64/xinetd-2.3.14-20.el5_10.x86_64.rpm.html

rpm -ivh xinetd-2.3.14-10.el5.x86_64.rpm

RSYNC服务端启动的两种方法

9、启动rsync服务端(独立启动)

[root@test home]# /usr/bin/rsync --daemon

10、启动rsync服务端 (有xinetd超级进程启动)

[root@test home]# /etc/init.d/xinetd reload

11 加入rc.local

在各种操作系统中,rc文件存放位置不尽相同,可以修改使系统启动时把rsync --daemon加载进去。

[root@test home]# vi /etc/rc.local

/usr/local/rsync –daemon #加入一行

12 检查rsync是否启动

[root@test home]# lsof -i :873

COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME

xinetd 4396 root 5u IPv4 633387 TCP *:rsync (LISTEN)

客户端配置

1 配置三个过程就可以了

1.1 设定密码文件

1.2 测试rsync执行指令

1.3 将rsync指令放入工作排程(crontab)

[root@aj1 home]# vi /etc/xinetd.d/rsync

# default: off

# description: The rsync server is a good addition to an ftp server, as it \

# allows crc checksumming etc.

service rsync

{

disable = yes

socket_type = stream

wait = no

user = root

server = /usr/bin/rsync

server_args = --daemon

log_on_failure += USERID

}

1.1 配置密码文件 (注:为了安全,设定密码档案的属性为:600。rsync.ps的密码一定要和Rsync Server密码设定案里的密码一样)

[root@aj1 home]# vi rsync.ps

sciooo

[root@aj1 home]# chown root.root .rsync.ps # 注意必须给权限

[root@aj1 home]# chmod 600 .rsync.ps # 必须修改权限

1.2 从服务器上下载文件

[root@aj1 rsync-3.0.4]# rsync -avz --password-file=/home/rsync.ps [email protected]::backup /home/

从本地上传到服务器上去

[root@aj1 rsync-3.0.4]# rsync -avz --password-file=/home/rsync.ps /home [email protected]::backup

rsync -avz --password-file=/home/rsync.ps /home/yitop/www/imgroot/test [email protected]::backup
