Environment:

Operating system: CentOS 7u3

Source server: 192.168.30.147

Target server: 192.168.30.148

Purpose: to synchronize the / home_test directory on the source server to the / home_test of the target server in real time

First turn off the selinux of the two devices

Temporarily change to setenforce 0, permanently change to modify / etc/sysconfig/selinux, modify SELINUX=enforcing to SELINUX=diabled or SELINUX=permissive

Install the Rsync server (centos2) on the target server

Install Rsync server software

Rhel7:

# yum-y install rsync

Create a rsyncd.conf profile

# vi / etc/rsyncd.conf # 7 has a default configuration file. If there is no default file on rhel6, you need to create your own configuration file. Add the following code

Log file = / var/log/rsyncd.log

Pidfile = / var/run/rsyncd.pid

Lock file = / var/run/rsync.lock

Secrets file = / etc/rsync.pass # user authentication configuration file, which stores the user name and password, which will be created later

Motd file = / etc/rsyncd.Motd # rsync Welcome information page file location at startup (file content customization)

[home_test] # synchronization module name

Path = / home_test # rsync server data directory path

Comment = home_test

Uid = root

Gid = root

Port=873

Use chroot = no

Read only = no

List = no # does not display the list of rsync server resources

Max connections = 200

Timeout = 600,

Auth users = user1 # user name to perform data synchronization. Multiple user names can be set, separated by commas in English.

Hosts allow = 192.168.30.147 # client IP addresses that allow data synchronization. Multiple addresses can be set, separated by commas in English.

Hosts deny = *

Create a user authentication file

# vim / etc/rsync.pass

User1:123456 # format, user name: password, can be set multiple, one user name per line: password, or use echo "user1:123456" > / etc/rsync.pass

Set file permissions

Chmod / etc/rsyncd.conf # sets the read and write permissions of the file owner

Chmod / etc/rsync.pass # sets the read and write permissions of the file owner

Mkdir / home_test

Start rsync

Centos7:

# systemctl restart rsyncd

Centos 6: yum-y install xinetd service is required

# / etc/init.d/xinetd start # launch

# service xinetd stop # stop

# service xinetd restart # restart

Part two: operate on the source server 192.168.30.147

First, install Rsync client software

# yum install rsync

Create an authentication password file

# vim / etc/rsync.pass

123456 # password

Chmod / etc/rsync.pass # sets file permissions, and only sets the file owner with read and write permissions

Mkdir / home_test/ceshi # create a test folder on the source server, and then run the following command on the source server

Rsync-avH-port=873-progress-delete / home_test/ user1@192.168.36.82::home_test/-password-file=/etc/rsync.pass

The test succeeded
