Installation

Wget http://rsync.samba.org/ftp/rsync/rsync-3.0.9.tar.gzwget http://rsync.samba.org/ftp/rsync/rsync-patches-3.0.9.tar.gztar zxvf rsync-3.0.9.tar.gztar zxvf rsync-patches-3.0.9.tar.gzcd rsync-3.0.9./configuremake & & make install

1. Create a profile

Vim / etc/rsyncd.conf; port=873uid=rootgid=rootmax connections=10log file=/var/log/rsyncd.logpid file=/var/run/rsyncd.pidlock file=/var/run/rsyncd.locksecrets file=/etc/rsyncd.passwd; hosts allow=192.168.11.0/27; hosts deny=192.168.11.0/255.255.255.224timeout=600 [backdir] comment= for client backpath=/home/backdir/read only = no;exclude=test;exclude from=/path/to/file;include from=/path/to/fileauth users= caide.me [share] comment= backup share filepath=/home/share/read only = yesauth users=caide.me

two。 Create a password file (/ etc/rsyncd.passwd)

Echo "caide.me:caide.me.passwd" > / etc/rsyncd.passwdchmod 600 / etc/rsyncd.passwd

3. Create xinetd snooping task (/ etc/xinetd.d/xinetd_rsync)

Vim / etc/xinetd.d/xinetd_rsync# default: off# description: The rsync server isa good addition to an ftp server, as it\ # allows crc checksumming etc.service rsync {disable = no socket_type = stream wait = no user = root server = / usr/local/bin/rsync server_args =-- daemon log_on_failure + = USERID} service xinetd restart

-> if necessary, the firewall needs to open port 873 of tcp protocol to install

Wget http://rsync.samba.org/ftp/rsync/rsync-3.0.9.tar.gzwget http://rsync.samba.org/ftp/rsync/rsync-patches-3.0.9.tar.gztar zxvf rsync-3.0.9.tar.gztar zxvf rsync-patches-3.0.9.tar.gzcd rsync-3.0.9./configuremake & & make install
