Installation of rsync

For security reasons, running the rsync server as an unprivileged user and group is encouraged. Create the rsyncd user and group with the following commands:

groupadd rsyncd &&
useradd -c rsyncd -d /home/rsync -g rsyncd -s /bin/false rsyncd

Install rsync by running the following commands:

./configure --prefix=/usr &&
make &&
make install 

Configuring rsync

Config files

/etc/rsyncd.conf

Configuration Information

This is a simple download-only configuration. See the rsyncd man-page for additional options (i.e., user authentication).

cat > /etc/rsyncd.conf << "EOF"
# This is a basic rsync configuration file
# It exports a single module without user authentication.

motd file = /home/rsync/welcome.msg
use chroot = yes

[localhost]
    path = /home/rsync
    comment = Default rsync module
    read only = yes
    list = yes
    uid = rsyncd
    gid = rsyncd

EOF

rsyncd init.d script

Note that you only want to start the rsync server if you want to provide a rsync archive on your machine. The rsync client doesn't need this script to be used.

Install the /etc/rc.d/init.d/rsyncd init script included in the blfs-bootscripts-5.1 package.

make install-rsyncd

Description

rsync

rsync is a replacement for rcp (and scp) that has many more features. It uses the "rsync algorithm" which provides a very fast method of syncing remote files. It does this by sending just the differences in the files across the link, without requiring that both sets of files are present at one end of the link beforehand.
