Server-side configuration: Rsync's configuration file is /etc/rsyncd.conf. Note that this file does not exist by default and needs to be created manually.

Here is a well-configured rsyncd.conf

##### #rsyncd. conf#######

uid = rsync---- à non-system virtual users

GID = rsync

maxconnections =-- à Maximum number of connections

Timeout =-- à Timeout period

pid File =/var/run/rsyncd.pid-- à the file where the process PID resides

lock File =/var/run/rsync.lock- à Lock

log file =/var/log/rsyncd.log- à log file with error

[Zhaofan]-- à Module

Auth users =rsync_backup- à Virtual User

Secrets file=/etc/rsync.password- à user-corresponding password file

###### #rsyncd. config########

The above is the configuration of the configuration file

Start the rsync service process:Rsync–daemon

Rsync the port is:873

[[Email protected] ~] #rsync--daemon

[[Email protected] ~] #netstat-lntup|grep 873

Actions required after the service starts:

[[email protected]/] #ls-DL Zhaofan

Drwxr-xr-x. 2root root 4096 Jan 9 12:06 Zhaofan

[Email protected]/]# useradd rsync-s/sbin/nologin

[Email protected]/]# chown-r rsync.rsync/zhaofan

[Email protected]/]# LS-DL Zhaofan

[Email protected]/]#

[[email protected]/] #echo "rsync_backup:zhaofan" >/etc/rsync.password

[Email protected]/]#

Here rsync_backup rsync's virtual user name,zhaofan is the password for Rsync's virtual username

[[email protected]/] #chmod /etc/rsync.password

[[email protected]/] #ls-dl/etc/rsync.password

-RW-------. 1root Root 9 12:10/etc/rsync.password

Also need to turn off Selinx and firewalls

All of the above server configurations are configured.

Here is the client configuration

echo "Zhaofan" >/etc/rsync.password

[[Email protected] ~] #chmod /etc/rsync.password

So far, all the configurations have been configured.

Note: The rsync command must be operated on the client.

Access via remote shell:

Pull:rsync [OPTION ...] [[email protected]] Host:src ... [DEST]

Push:rsync [OPTION ...] Src... [[email protected]] Host:dest

Access via rsync daemon:

Pull:rsync [OPTION ...] [[email protected]] Host::src ... [DEST]

rsync [OPTION ...] rsync://[[email protected]]host[:P ort]/src ... [DEST]

Push:rsync [OPTION ...] Src... [[email protected]] HOST::D EST

rsync [OPTION ...] Src...rsync://[[email protected]]host[:P Ort]/dest
