Server:备份端192.168.71. 134

Client1:被备份端192.168.71.133

Client2:被备份端192.168.71. 132

Server：备份端192.168.71. 134

(1)安装rsync

[root@localhost ~]#cd Desktop/
[root@localhost Desktop]#tar zxf rsync-3.0.9.tar.gz -C /opt/
[root@localhost Desktop]#cd /opt/rsync-3.0.9/
[root@localhost inotify-tools-3.13]#./configure;make && make install

(2)配置rsync（/etc/rsyncd.conf，该文件默认不存在，需手动创建，并进行配置）

[root@localhost ~]# vi /etc/rsyncd.conf
uid = nobody
gid = nobody
ignore errors
read only = no
write only = no
list = false
use chroot = no
max connections =10
strict modes = yes
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
[client1]
path = /tongbu
comment = client1 tongbu  file
hosts allow = 192.168.71.133
hosts deny = *
uid = root
gid = root
auth users = user1
secrets file = /etc/client1.pass
[client2]
path = /tongbu2
comment = client2 tongbu  file
hosts allow = 192.168.71.132
hosts deny = *
uid = root
gid = root
auth users = user2
secrets file = /etc/client2.pass

(3)测试

[root@localhost ~]#mkdir /tongbu 
[root@localhost ~]#mkdir /tongbu2
[root@localhost tongbu]# cat /etc/client1.pass
user1:123
[root@localhost tongbu]# cat /etc/client2.pass
user2:321
[root@localhost tongbu]# ll /etc/client*
-rw------- 1 root root 10 Apr  5 02:38 /etc/client1.pass
-rw------- 1 root root 10 Apr  5 03:24 /etc/client2.pass
[root@localhost ~]# /usr/local/bin/rsync –daemon       开启守护进程
[root@localhost ~]#echo “/usr/local/bin/rsync –daemon” >> /etc/rc.local  设置开机自动运行

[root@localhost ~]# ps -ef|grep rsync                  查看守护进程是否开启
root     16592     1  0 00:46 ?        00:00:00 /usr/local/bin/rsync --daemon
[root@localhost ~]# lsof -i:873                    查看默认端口873是否开启
COMMAND   PID USER   FD   TYPE DEVICE SIZE NODE NAME
rsync   16592 root    4u  IPv6  65197       TCP *:rsync (LISTEN)
rsync   16592 root    5u  IPv4  65198       TCP *:rsync (LISTEN)

Client1:被备份端192.168.71. 133

(1)安装rsync

[root@localhost ~]#cd Desktop/
[root@localhost Desktop]#tar zxf rsync-3.0.9.tar.gz -C /opt/
[root@localhost Desktop]#cd /opt/rsync-3.0.9/
[root@localhost inotify-tools-3.13]#./configure;make && make install

(2)安装inotify

[root@localhost ~]# cd Desktop/
[root@localhost Desktop]# tar xfz  inotify-tools-3.13.tar.gz -C /opt/
[root@localhost Desktop]# cd /opt/inotify-tools-3.13/
[root@localhost inotify-tools-3.13]# ./configure;make && make install

(3)创建测试目录，密码文件以及同步所用脚本

[root@localhost ~]#mkdir /tongbu
[root@localhost tongbu]# cat /etc/client1.pass
123
[root@localhost tongbu]# ll /etc/client1.pass
-rw------- 1 root root 4 Apr  5 17:29 /etc/client1.pass
[root@localhost tongbu]# cat inotifyrsync.sh
#!/bin/bash
host=192.168.71.133
src=/tongbu/
dst=client1
user=user1
/usr/local/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f%e' -e modify,delete,create,attrib $src |while read files
        do
/usr/bin/rsync -vzrtopg --delete --progress --password-file=/etc/client1.pass $src $user@$host::$dst
           echo " was  rsynced" >> /tmp/rsync.log 2>&1
        done

(4)给inotify脚本添加可执行权限，并在后台运行，以及开机自起

[root@localhost tongbu]# chmod 755  inotifyrsync.sh
[root@localhost tongbu]# ./inotifyrsync.sh  &    需要备份端以此脚本作为守护进程
[root@localhost tongbu]#echo  “/web/wwwroot/inotifyrsync.sh &” >> /etc/rc.local  开机自动运行

Client2:被备份端192.168.71.132

(1)安装rsync

[root@localhost ~]#cd Desktop/
[root@localhost Desktop]#tar zxf rsync-3.0.9.tar.gz -C /opt/
[root@localhost Desktop]#cd /opt/rsync-3.0.9/
[root@localhost inotify-tools-3.13]#./configure;make && make install

(2)安装inotify

[root@localhost ~]# cd Desktop/
[root@localhost Desktop]# tar xfz  inotify-tools-3.13.tar.gz -C /opt/
[root@localhost Desktop]# cd /opt/inotify-tools-3.13/
[root@localhost inotify-tools-3.13]# ./configure;make && make install

(3)创建测试目录，密码文件以及同步所用脚本

[root@localhost ~]#mkdir /tongbu2
[root@localhost tongbu2]# cat /etc/client2.pass
321
[root@localhost tongbu2]# ll /etc/client2.pass
-rw------- 1 root root 4 02-24 00:12 /etc/client2.pass
[root@localhost tongbu2]# cat inotifyrsync.sh
#!/bin/bash
host=192.168.71.132
src=/tongbu2/
dst=client2
user=user2
/usr/local/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f%e' -e modify,delete,create,attrib $src |while read files
        do
   /usr/bin/rsync -vzrtopg --delete --progress --password-file=/etc/client2.pass $src $user@$host::$dst
           echo " was  rsynced" >> /tmp/rsync.log 2>&1
        done

(4)给inotify脚本添加可执行权限，并在后台运行，以及开机自起

[root@localhost tongbu2]# chmod 755  inotifyrsync.sh
[root@localhost tongbu2]# ./inotifyrsync.sh  &    需要备份端以此脚本作为守护进程

现在，大家就可以测试了：分别在Rsync被备份端的/tongbu，/tongbu2目录下创建文件，看是否能实时备份到Rsync Server备份端的/tongbu及/tongbu2目录下，本人测试是ok的，有啥问题，可留言
