Quickly build an efficient Rsync service using Shell scripts

During our daily O & M, we often encounter the need to set up the rsync service, such as website file synchronization (image or backup), patch update, disaster Tolerance and backup for various different machine backups. If you write the rsync service as a script, you can have a basic service framework after the script is executed. You only need to further improve the details and security requirements, this improves our work efficiency.

Many Linux systems, such as RHEL and CentOS, are installed with rsync 2 by default. version x, and I recommend 3. version x, because 3. x improves the synchronization algorithm to make it more efficient.

1) download the latest stable version of rsync-3.0.8
[Root @ server ~] # Cd tools
[Root @ server tools] # wget-chttp: // rsync.samba.org/ftp/rsync/src/rsync-3.0.8.tar.gz
2) Compile and install rsync-3.0.8
[Root @ servertools] # tar xf rsync-3.0.8.tar.gz
[Root @ server tools] # cd rsync-3.0.8
[Root @ server rsync-3.0.8] #./configure & make
3) after compilation and installation, it will generate the rsync binary file in the rsync-3.0.8/directory, copy it to/usr/local/bin:
[Root @ server rsync-3.0.8] # \ cp rsync/usr/local/bin

PS: both the server and the client must perform the above installation operations. If both the client and the server are a type of operating system, you can compile and install it once, then, the rsync BINARY command is distributed to/usr/local/bin/of other servers.

4) edit the Rsync service build script (rsync_server_set.sh) on the server)
[Root @ server] # cd shells/
[Root @ server shells] # vi rsync_server_set.sh

#! /Bin/bash
#
# Script Name: rsync_server_set.sh
# Description: set rsync service quickly.

# $ Rsync-avz/root/admin/xxx.txt $ address: mystation
# $ Rsync-avz $ address: xxx_client // home/

$ Rsync -- daemon -- config = $ conf_file

Cat>/etc/rc. local <EOF
# Rsync daemon $ date
$ Rsync -- daemon -- config = $ conf_file

Exit 0

5) run the script on the server to build the Rsync service.
[Root @ server shells] # chmod 755 rsync_server_set.sh
[Root @ server shells] #./rsync_server_set.sh
