CentOS6.5 Rsync服务

rsync介绍

rsync是类unix系统下的数据镜像备份工具

主要有以下三种用法：

1、本地备份

例：[[email protected]~]#rsync /data/ /home/oldboy/

2、远端备份

例：pull

[[email protected]
~]# rsync
-avz oldboy.txt -e ‘ssh‘  192.168.129.128:~

push

[[email protected]
~]# rsync
-avz -e ‘ssh‘ 192.168.129.128:~/f1 ./

3、daemon模式备份

以守护进程（socket）的方式传输数据（这个是rsync自身的重要功能）

rsync daemon模式配置

服务端：

[[email protected] ~]#vi /etc/rsyncd.conf

创建rsync默认配置文件路径 /etc/rsyncd.conf 将 默认配置考到此文件内

以下是默认配置

#rsync_config___________start

#created by oldboy
16:01 2016-12-02

##rsyncd.conf
start##

uid = rsync

gid = rsync

use
chroot = no

max connections =
200

timeout = 300

pid file =
/var/run/rsyncd.pid

lock file =
/var/run/rsync.lock

log file =
/var/log/rsyncd.log

[oldboy]

path = /oldboy/

ignore errors

read only = false

list = false

hosts allow =
192.168.0.0/24

hosts deny =
0.0.0.0/32

auth users =
rsync_backup

secrets file =
/etc/rsync.password

#rsync_config_________end

rsyncd.conf 里面的共享目录 oldboy 要存在

启动服务之后的操作

[[email protected] ~]# mkdir/oldboy -p

[[email protected] ~]# useradd
rsync -s /sbin/nologin

[[email protected] ~]# chown
-R rsync.rsync /oldboy

[[email protected] ~]# echo"rsync_backup:oldboy" >/etc/rsync.password

[[email protected] ~]# chmod600 /etc/rsync.password

[[email protected] ~]# rsync --daemon

注：rsync --daemon 可以放入/etc/rc.local 开机启动

[[email protected] ~]# netstat -lntup|grep 873

至此服务端配置完毕

客户端：

[[email protected] ~]# echo"rsync_backup:oldboy" >/etc/rsync.password

[[email protected] ~]# chown 600
/etc/rsync.password

[[email protected] ~]# rsync
-avz [email protected]::oldboy /tmp/
--password-file=/etc/rsync.password

[[email protected] tmp]# rsync -avz /tmp/ [email protected]::oldboy --password-file=/etc/rsync.passwordsending incremental file list
