Experimental topology: HK36 ( Server 192.168.2.102 )====HK46 (Client 192.168.2.190 )
Experimental requirements: backup the HK46 /data/ directory to /backup/ of HK36
(1) The rsync service depends on the xinetd super service management, first install the xinetd service
[root@HK36 ~]# yum -y install xinetd
(2) Enter rsync to modify the configuration file information, change disable = yes to no, restart the service, and check whether port 873 is up
[root@HK36 ~]# service xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]
[root@HK36 ~]# netstat -anptu | grep 873
tcp 0 0 :::873 :::* LISTEN 2729/xinetd
(3) Create a non-system test user and give the user nobody permission to the directory /backup
[root@HK36 backup]# vim /etc/rsyncd.conf
uid = nobody
gid = nobody
address = 192.168.2.102
pid = 873
host allow = 192.168.2.190
use chroot = yes
max_connetion = 5
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsyncd.lock
log file = /var/log/rsyncd.log
motd file = /etc/rsyncd.motd
[backup]
path = /backup/
comment = data for backup
read only = no
auth users = gz
list = yes
[root@HK36 backup]# chown nobody:nobody /backup/
[root@HK36 backup]# vim /etc/rsyncd.motd Create login template file
welcome to backup data!
[root@HK36 backup]# vim /etc/rs.passwd create password
gz:ggrr50152412
(4) Test, create a backup directory test under HK46:
[root@HK36 /]# mkdir /backup/
[root@HK46 /]# mkdir /data/
[root@HK46 data]# ls
22 55 a aaaaa erer kd s test
[root@HK46 data]# rsync -avz ./ --delete [email protected]::backup
(5) Upload inotify and unzip the installation
[root@HK46 ~]# tar -xvf inotify-tools-3.14.tar.gz -C /usr/local/src/
[root@HK46 inotify-tools-3.14]#./configure --prefix=/usr/local/inotify-tools;make;make install
(6) Call the command directly
[root@HK36 ~]# ln -s /usr/local/inotify-tools/bin/* /usr/bin/
[root@HK46 ~]# vim /root/passfile Create password file
ggrr50152412
[root@HK46 data]# chmod 600 /root/passfile and give 600 permission
(7) Test
(8) Edit the script and give execute permission
#!/bin/bash
backup_Server=192.168.2.102
/usr/bin/inotifywait -mrq --format '%w%f' -e create,close_write,delete /data/ | while read line
do
cd / data /
rsync -az ./ --delete gz@$backup_Server::backup --password-file=/root/ passfile
done
[root@HK46 ~]# vim inotify.sh
(9) The test is successful
