1. Confgiure the Slave Server

Install Rsync on the Slave Server

[root@slave ~]# rpm -ivh rsync-3.1.2-11.el7_9.x86_64.rpm

Configure Rsync on the Slave Server

[root@slave ~]# vim /etc/rsyncd.conf

log file=/var/log/rsync.log pid file=/var/run/rsyncd.pid [server] path=/root/test use chroot=true max connections=4 read only=no list=true uid=root gid=root auth users=root secrets file=/etc/rsync.password hosts allow=X.X.X.X

Create User and Password File for Synchronization

[root@slave ~]# echo "root:123456" >/etc/rsync.password

[root@slave ~]# chmod 600 /etc/rsync.password

Create the Synhcronization Directory

[root@slave ~]# mkdir -p /root/test

Start the Daemon and Add to Startup

[root@slave ~]# rsync --daemon --config=/etc/rsyncd.conf

[root@slave ~]# echo "rsync --daemon --config=/etc/rsyncd.conf" >>/etc/rc.local

[root@slave ~]# chmod +x /etc/rc.d/rc.local

[root@slave ~]# tail -1 /etc/rc.local

[root@slave ~]# reboot

[root@slave ~]# systemctl status rc-local.service

[root@slave ~]# netstat -ntlp | grep rsync

2. Configure the Master Server

Install Rsync on the Master Server

[root@master ~]# rpm -ivh rsync-3.1.2-11.el7_9.x86_64.rpm

Create the Password File on the Master Server

[root@master ~]# echo "123456" >/etc/rsync.password

[root@master ~]# chmod 600 /etc/rsync.password

Deploy sersync

[root@master ~]# mkdir /usr/local/sersync/

[root@master ~]# mkdir /usr/local/sersync/bin

[root@master ~]# mkdir /usr/local/sersync/conf

[root@master ~]# mkdir /usr/local/sersync/logs

[root@master ~]# cd /usr/local/sersync

Copy sersync package sersync2.5.4_64bit_binary_stable_final.tar.gz into this directory.

[root@master sersync]# tar xvf sersync2.5.4_64bit_binary_stable_final.tar.gz

[root@master sersync]# mv GNU-Linux-x86/sersync2 ./bin/sersync

[root@master sersync]# mv GNU-Linux-x86/confxml.xml ./conf/

[root@master conf]# cp confxml.xml confxml.xml.bak

Modify the config.xml File

[root@master sersync]# vim conf/confxml.xml

Add sersync to PATH

[root@master sersync]# echo "export PATH=$PATH:/usr/local/sersync/bin/" >>/etc/profile

[root@master sersync]# source /etc/profile

[root@master sersync]# which sersync

Start sersync

[root@master sersync]# sersync -d -r -o /usr/local/sersync/conf/confxml.xml

Test Synchronization

[root@master sersync]# cd /root/gckj/

[root@master sersync]# mkdir note

[root@slave backup]# ls

Add to Startup and Reboot

[root@master ~]# ln -s  /usr/local/sersync/bin/sersync /usr/local/bin/sersync

[root@master ~]# echo "sersync -d -r -o /usr/local/sersync/conf/confxml.xml" >>/etc/rc.local

[root@master ~]# chmod +x /etc/rc.d/rc.local

[root@master ~]# systemctl status rc-local.service

[root@master ~]# tail -1 /etc/rc.local

[root@slave ~]# reboot

Verify Synchronization After Reboot

[root@master sersync]# cd /root/test/

[root@master sersync]# mkdir note

[root@slave backup]# ls
