The rsync package contains the rsync utility. This is useful for synchronizing large file archives over a network.

For security reasons, running rsync server as an unprivileged user and group is encouraged.
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 |
--prefix=/usr : This installs rsync in /usr instead of /usr/local
/etc/rsyncd.conf
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 |
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. Having said that, if you want to run the rsync daemon, the rsync daemon init.d script can be created using the following commands:
cat > /etc/rc.d/init.d/rsyncd << "EOF" #!/bin/sh # Begin $rc_base/init.d/rsyncd # Based on sysklogd script from LFS-3.1 and earlier. # Rewritten by Gerard Beekmans - [email protected] source /etc/sysconfig/rc source $rc_functions case "$1" in start) echo "Starting RSYNC Server..." loadproc /usr/bin/rsync --daemon --compress ;; stop) echo "Stopping RSYNC Server..." killproc /usr/bin/rsync ;; reload) echo "Reloading RSYNC Server..." reloadproc /usr/bin/rsync ;; restart) $0 stop sleep 1 $0 start ;; status) statusproc /usr/bin/rsync ;; *) echo "Usage: $0 {start|stop|reload|restart|status}" exit 1 ;; esac # End $rc_base/init.d/rsyncd EOF chmod 755 /etc/rc.d/init.d/rsyncd |
Create the symbolic links to this file in the relevant rc.d directories with the following commands:
cd /etc/rc.d/init.d && ln -sf ../init.d/rsyncd ../rc0.d/K30rsyncd && ln -sf ../init.d/rsyncd ../rc1.d/K30rsyncd && ln -sf ../init.d/rsyncd ../rc2.d/K30rsyncd && ln -sf ../init.d/rsyncd ../rc3.d/S30rsyncd && ln -sf ../init.d/rsyncd ../rc4.d/S30rsyncd && ln -sf ../init.d/rsyncd ../rc5.d/S30rsyncd && ln -sf ../init.d/rsyncd ../rc6.d/K30rsyncd |
The rsync package contains 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 for remote files into sync. 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 of the ends of the link beforehand.
