Configure rsync to synchronize data to the RPM package to install rsync and configure

[[Email protected] Home] # rpm-Qa | grep rsync # Check whether the rsync package is installed.
Rsync-2.6.8-3.1
[[Email protected] centos] # rpm-IVH rsync-2.6.8-3.1.i386.rpm # Install Manually If Not Installed

[[Email protected] rsync-3.0.4] # Vim/etc/xinetd. d/rsync


1 configure rsync servervi/etc/xinetd. d/rsync
Change disable = yes to no

Service rsync
{
Disable = No
Socket_type = stream
Wait = No
User = root
Server =/usr/bin/rsync
Server_args = -- daemon
Log_on_failure + = userid
}

2 configure rsync to start automatically
[[Email protected] etc] # chkconfig rsync on
[[Email protected] etc] # chkconfig rsync -- list
Rsync on

3. Configure rsyncd. conf
[[Email protected] etc] # Vim rsyncd. conf

Uid = root
Gid = root
Use chroot = No
Max connections = 4
Strict modes = Yes
Port = 873
PID file =/var/run/rsyncd. PID
Lock file =/var/run/rsync. Lock
Log File =/var/log/rsyncd. Log

[Backup]
Path =/srv
Comment = This is test
Auth users = scihoo
Uid = root
Gid = root
Secrets file =/home/rsync. Ps
Read Only = No
List = No


4. Make sure that the rsync port number in ETC/services is correct.
[[Email protected] etc] # Vim/etc/services
Rsync 873/tcp # rsync
Rsync 873/udp # rsync

5. Configure the rsync password (the path has been written in the preceding configuration file)/home/rsync. PS (name can be written at will, as long as it is consistent with the above configuration file), format (one row per user)
[[Email protected] etc] # vi/home/rsync. Ps
Scihoo: scihoo

6. Configure rsync Password File Permissions
[[Email protected] Home] # chown root. Root rsync. Ps
[[Email protected] Home] # chmod 400 rsync. Ps

7 STARTUP configuration
[[Email protected] Home] #/etc/init. d/xinetd restart
Stopping xinetd: [OK]
Starting xinetd: [OK]

8. If xinetd does not exist, install it.
[[Email protected] Home] # Yum-y install xinetd


Start rsync server
Two Methods for rsync server startup
9. Start the rsync server (independently started)
[[Email protected] Home] #/usr/bin/rsync -- daemon

10. Start the rsync server (xinetd superprocess started)
[[Email protected] Home] #/etc/init. d/xinetd reload

11 add RC. Local
In various operating systems, RC files are stored in different locations and can be modified so that rsync-daemon can be loaded during system startup.
[[Email protected] Home] # vi/etc/rc. Local
/Usr/local/rsync-daemon # Add a row

12. Check whether Rsync is enabled.
[[Email protected] Home] # lsof-I: 873
Command PID user FD type device size node name
Xinetd 4396 root 5u IPv4 633387 tcp *: rsync (Listen)




Client Configuration
1. Configure three processes.
1.1 SET Password File
1.2 test the rsync execution command
1.3 put the rsync command into the Job Schedule (crontab)
[[Email protected] Home] # vi/etc/xinetd. d/rsync

# Default: Off
# Description: the rsync server is a good addition to an FTP server, as it \
# Allows CRC checksumming etc.
Service rsync
{
Disable = Yes
Socket_type = stream
Wait = No
User = root
Server =/usr/bin/rsync
Server_args = -- daemon
Log_on_failure + = userid
}

1.1 configure the password file (NOTE: For security purposes, set the attribute of the password file to 600. The Rsync. PS password must be the same as the password in the rsync server password setting case)
[[Email protected] Home] # vi rsync. Ps
Sciooo

[[Email protected] Home] # chown root. Root. rsync. PS # grant permissions
[[Email protected] Home] # chmod 600. rsync. PS # The permission must be modified.

1.2 download files from the server
[[Email protected] rsync-3.0.4] # rsync-avz -- password-file =/home/rsync. PS [email protected]: backup/home/

Upload from local to server
[[Email protected] rsync-3.0.4] # rsync-avz -- password-file =/home/rsync. PS/home [email protected]: Backup
