1. Build rsync server

Systemctl start rsyncd

Systemctl enable rsyncd

Systemctl status rsyncd

Ss-ntl | grep 873

Rpm-ql rsync

two。 Modify the configuration file

Vi / etc/rsyncd.conf

Uid = root

Gid = root

Use chroot = no

Max connections = 0

Ignore errors

Exclude = lost+found/

Log file = / var/log/rsyncd.log

Pid file = / var/run/rsyncd.pid

Lock file = / var/run/rsyncd.lock

Reverse lookup = no

Hosts allow = 192.168.8.0 Compact 24 # client IP

[backup]

Path = / backup/

Comment = backup

Read only = no

Auth users = rsyncuser

Secrets file = / etc/rsync.pass

3. Create a rsync backup server directory

Mkdir / backup

The server generates a verification file

Echo "rsyncuser:magedu" > / etc/rsync.pass

Chmod 600 / etc/rsync.pass

 server-side preparation directory

Mkdir / backup

The server starts the rsync service

Rsync-daemon can join / etc/rc.d/rc.local to realize boot

Systemctl start rsyncd CentOS 7

Client configuration password file

Echo "magedu" > / etc/rsync.pass

Chmod 600 / etc/rsync.pass

Client

Turn on inotify

Yum-y install inotify-tools

4. Client test synchronization data

Rsync-avz-- password-file=/etc/rsync.pass / data/backup rsyncuser@rsync server IP::backup

5. Client create inotify_rsync.sh script

Vim inotify_rsync.sh #! / bin/bash

SRC='/data/backup/'

DEST='rsyncuser@rsync server IP::backup'br/ > #! / bin/bash

SRC='/data/backup/'

DEST='rsyncuser@rsync Server IP::backup'

Do

FILEPATH=$ {DIR} ${FILE}

Rsync-az-- delete-- password-file=/etc/rsync.pass $SRC $DEST &

Echo "At ${TIME} on ${DATE}, file $FILEPATH was backuped up via rsync"

/ var/log/changelist.log

Done

Chmod + x inotify_rsync.sh

Start the background monitoring process

6.sh inotify_rsync.sh &

Ps-ef | grep inotify_rsync

Note: both hosts must enable ssh secret-free login, allowing clients to distribute data to rsync servers.
