rsync备份项目

rsync的同步都不是实时同步的,操作一次才能同步一次,即使放定时任务,也不是实时同步。

rsync项目1  rsync命令本地同步备份

一 使用rsync实现数据本地同步备份(前提:本地无需开启rsync服务,但要安装rsync命令)

常见的备份时保持文件属性不变的选项:-avz, 下面的-av,也可以写成-avz

v显示详细信息,z传输时进行压缩以提高效率。a归档,递归传输文件,并保持属性,等于-rtopgDl.

1 rsync  -av  要备份的目录     备份到的目录               //同步备份整个目录

2 rsync  -av  要备份的目录 /   备份到的目录               //同步备份目录下的各个文件

3 rsync  - -delete  -av  要备份的目录 /   备份到的目录    //删除目录位置有而原始位置没有的文件

4 rsync  -av  --bwlimit=100  要备份的目录 /   备份到的目录  //同步限速为100kb

注意3中:

-av和- -delete的顺序无所谓,前面目录有啥,后面目录就有啥,前面目录如果为空,后面也为空,后面跟随前面。

本地机器上配置:

1)安装rsync命令,(不是启动rsync服务):yum   -y  install  rsync

2)建立测试文件:mkdir  /yuanshi, echo  “1111” > /yuanshi/a.txt,  echo  “2222” > /yuanshi/b.txt

3)用三种方法使用rsync命令备份:

a)rsync  -av  /yuanshi    /beifen            //同步备份整个目录,连yuanshi的目录名一块备份下来

此时查看:/yuanshi目录下:有a.txt和b.txt,   /beifen目录下有:/yuanshi/ 、a.txt和b.txt

b)rsync  -av  /yuanshi/   /beifen            //同步备份目录下的各个文件,只备份yuanshi目录名中文件。

此时查看:/yuanshi目录下:有a.txt和b.txt,   /beifen目录下有:a.txt和b.txt

c)  rm  -rf  /yuanshi/a.txt  ,此时:/yuanshi目录下有:b.txt,  /beifen目录下有:a.txt和b.txt

rsync  - -delete  -av /yuanshi/  /beifen/

此时查看:/yuanshi目录下有:b.txt,  /beifen目录下有:b.txt

例子:rsync的删除功能。--delete

[root@localhost 桌面]# mkdir /test/

[root@localhost 桌面]# echo "1111" > /test/a.txt

[root@localhost 桌面]# echo "2222" > /test/b.txt

[root@localhost 桌面]# ls /test/

a.txt  b.txt

[root@localhost 桌面]# mkdir /null

[root@localhost 桌面]# ls /null/

[root@localhost 桌面]# rsync -av --delete /null/ /test/

[root@localhost 桌面]# ls /null/

[root@localhost 桌面]# ls /test/

rsync项目2  rsync命令+ssh远程同步备份

使用rsync+ssh实现数据远程同步备份,实现远程下载和上传文件的同步备份

1把远程机上的文件目录下载到本机目录:(远程:安装rsync命令,sshd服务,远程机有用户,  本地:rsync命令)

rsync  -av  远程机用户名@远程机IP地址:/远程机目录    本地目录

rsync  -av  - -delete  远程机用户名@远程机IP地址:/远程机目录   本地目录

rsync  -av  --bwlimit=100 远程机用户名@远程机IP地址:/远程机目录    本地目录     //下载时限速为100k

2把本机目录文件上传到远程机目录:(远程:安装rsync命令,sshd服务,远程机有用户,  本地:rsync命令)

rsync  -av  本地目录   远程机用户名@远程机IP地址:/远程机目录   

rsync  -av  - -delete  本地目录   远程机用户名@远程机IP地址:/远程机目录   

rsync  -av  --bwlimit=100  本地目录   远程机用户名@远程机IP地址:/远程机目录      //上传时限速为100k

注意- -delete选项是指:删除目录位置有而原始位置没有的文件,也就是说,后面目录要跟着前面目录同步。前面有啥,后面就跟着有啥。

例子:服务端和客户端都是root账户和root密码时的rsync数据同步。

服务器端配置

1)双方都用root账户来连接,密码都是123456

2)安装rsync服务:  yum -y install rsync

3)需要启动sshd服务,因为rsync备份的传输端口就是通过sshd的22端口传输的.

4)关闭iptables,/etc/init.d/iptables

5)关闭selinux,   setenforce  0,  或者修改配置文件永久关闭

6)创建测试文件/yuanshi/a.txt,/yuanshi/b.txt

7)创建接收目录,mkdir  /jieshou

8)chmod -R o+w /jieshou/

客户端备份服务器上的文件:    //远程下载

创建备份目录和备份文件,mkdir /beifen,  rsync  -av  [email protected]:/yuanshi/  /beifen/  

回车后,输入对方root的密码123456,即可备份成功。此时,客户端/beifen目录下有a.txt和b.txt

此时服务器端删除一个文件

rm  -rf /yuanshi/a.txt,  现在服务器上只剩下b.txt

此时,客户端再备份服务器上的文件:另一方法)

rsync –av  - -delete  [email protected]:/yuanshi/  /beifen/  

回车后,输入root的密码123456即可备份,现在客户端 /beifen目录下有的文件是:b.txt

客户上传本地文件到服务器 //远程上传

mkdir /c

echo "cccc" > /c/c.txt

yum -y install rsync

rsync -av /c/  [email protected]:/jieshou

输入对方root密码 123456即可上传到服务器。

案例1:服务端和客户端都是root账户和root密码时的rsync数据同步。

(服务器端需要:启动sshd服务,rsync命令,用户名和对应密码但客户端不需要启动这些服务,只需有rsync命令

rsync项目3  搭建rsync服务共享方法让客户端来同步服务器上的文件

使用rsync服务实现数据远程同步备份,通过服务器上设置服务,客户端来同步方法。

rsync服务器上:需要开启rsync服务,sshd服务,有用户,本地客户端:rsync命令,无需开:sshdrsync服务

服务器端一旦配置好rsync服务,上传和下载文件操作都是在客户端进行。

客户端远程查看: rsync  -av  服务器IP::

客户端远程下载:

rsync  -av  服务器用户名:服务器IP::共享目录名     本地目录

rsync  -av  --delete  服务器用户名:服务器IP::共享目录名     本地目录

rsync  -av  --bwlimit=100 服务器用户名:服务器IP::共享目录名     本地目录     //下载时限速为100k

客户端远程上传:

rsync  -av  本地目录  服务器用户名:服务器IP::共享目录名

rsync  -av  - -delete  本地目录  服务器用户名:服务器IP::共享目录名

rsync  -av  --bwlimit=100 本地目录  服务器用户名:服务器IP::共享目录名       //上传时限速为100k

注意项目3不适合通道方法,即使改变sshd端口号,也不能用指定通道方法,因为输入的密码是对方机器指定的密码,不是对方系统密码,不适合秘钥对无密码连接,想无密码连接方法就是建立并指定对方设置的密码文件。

-av和- -delete的顺序无所谓,前面目录有啥,后面目录就有啥,前面目录如果为空,后面也为空,后面跟随前面。

例子: 服务端和客户端都是用root账户登陆时候的rsync数据同步。

rsync服务器上配置(192.168.4.5)

1)建立测试文件:mkdir /homework,  echo "1111" > /homework/1.txt,   echo "2222" > /homework/2.txt

2)useradd  rsync  -s /sbin/nologin

3) 修改配置文件,创建共享文件的路径和设置

vim /etc/rsyncd.conf               //本身没有这个文件,需要自己写

uid=rsync

gid=rsync

max connections=200                 //能连接rsync服务器的最大客户端连接数为200

timeout=300                         //连接rsync服务器的超时时间

pid file=/var/run/rsyncd.pid        //进程的pid编号放到文件里面

lock file=/var/run/rsyncd.lock      //文件锁的机制,多个文件需要同时同步时上锁,一个一个同步,防止冲突

log file=/var/log/rsyncd.log        //log日志,将来出错了,有任何问题看log

[homework]                          //共享目录名

comment this is student homework

path=/homework                     //共享目录的路径

read only=yes                      //注意:上传时需要改为no或false

auth users=student                 //这里的用户名和系统用户名不冲突,可以不是系统用户名。它是虚拟用户

secrets file=/etc/password.txt     //用户对应的密码文件,路径可自定义

list=false                         //false表示不允许列表,所有都允许,如果只允许一部分时候,可以为yes

hosts allow=192.168.4.0/24         //允许的网段访问我rsync服务

hosts deny=10.10.10.0/24           //拒绝的网段访问我rsync服务

4)根据共享文件的配置文件,设置用户名和密码

vim  /etc/password.txt

student:456

chmod 600 /etc/password.txt

5)安装rsync服务:yum  -y  install  rsync

6)安装xinetd服务:yum  -y  install  xinetd

7)修改配置文件,唤醒rsync服务

vim /etc/xinetd.d/rsync

disable = no

/etc/init.d/xinetd restart

7)需要启动sshd服务,因为rsync备份的传输端口就是通过sshd的22端口传输的

8)关闭iptables,/etc/init.d/iptables  stop

9) 关闭selinux,   setenforce  0,  或者修改配置文件永久关闭

10)给共享目录加一个w权限,供客户端上传用: chmod  o+w  /homework

注意:上面rsync启动是用xinetd带动启动的,也可以用下面守护进程方式启动:

[root@localhost 桌面]# rsync --daemon  //以守护进程模式启动。启动后是873端口。

客户端下载服务器上共享文件:(192.168.4.205)

查看服务器上的共享文件: rsync  -av  192.168.4.5::   查看不到,但能下载

远程同步下载:(一般方式同步下载)

mkdir /beifen,   rsync  -av  [email protected]::homework  /beifen/

输入服务器给的用户名student对应的密码:456,可以下载下来,此时:客户端/beifen目录下有:1.txt和2.txt

将rsync服务器上的一个文件删除

rm  -rf  /homework/1.txt,  现在服务器上只有2.txt了  ,而客户端上有:1.txt和2.txt

远程同步下载:(另一个方式同步下载)

rsync  -av  - -delete  [email protected]::homework  /beifen/ ,此时,客户端只有2.txt了

客户端把本地的文件上传到服务器的共享目录中:(192.168.4.205)

注意:上传时服务器上需要将配置文件/etc/rsyncd.conf的read only改为no, read only=no

上传:rsync  -av /a/ [email protected]::homework 

输入服务器指定的用户名student的密码:456, 即可上传成功。

此时服务器上/homework目录下有:2.txt   a.txt   b.txt

注意:下载和上传不需要输入对方密码的设置

客户端设置:

[root@localhost 桌面]# echo “456” > /etc/rsy.passwd           //客户端先将服务器端给的密码写入一个文件

rsync  -av  [email protected]::homework  /beifen/   --password-file=/etc/rsy.passwd 不输密码,即可下载

rsync  -av /a/ [email protected]::homework   --password-file=/etc/rsy.passwd 不输密码,即可上传

案例1: 服务端和客户端都是用root账户登陆时候的rsync数据同步。

[root@localhost 桌面]# echo "456" > /etc/abc.passwd          //客户端先将服务器端给的密码写入一个文件

[root@localhost 桌面]# chmod 600 /etc/abc.passwd             //必须要有这一步骤,否则还需要输入密码

rsync -av --exclude-from=/root/download_pc.log [email protected]::homework  /beifen/ 

--password-file=/etc/abc.passwd                                              不输入密码,即可下载

rsync -av --exclude-from=/root/upload_pc.log /a/ [email protected]::homework  \

--password-file=/etc/abc.passwd                                              不输入密码,即可上传

2)排除多个还可用下面方法,和上面效果一一样。

下载排除多个: rsync -av --exclude={1.txt,2.txt} [email protected]::homework   /beifen/

上传排除多个:rsync -av --exclude={a.txt,b.txt} /a/ [email protected]::homework 

rsync下载和上传时候排除不需要同步的内容(服务端设置排除

案例7: 服务端和客户端都是用root账户登陆时候的rsync数据同步。(另一种启动方式:rsync --daemon

下载和上传时候排除不需要同步的内容(服务端设置排除多个)

rsync无差异同步(有数据丢失风险

案例8: 服务端和客户端都是用root账户登陆时候的rsync数据同步。(另一种启动方式:rsync --daemon

原先服文件一致,当服务器端数据删除,客户端也跟着删除,服务端增加,客户端也跟着增加,客户端根据服务器数据进行同步。
