Linux site group rsync Synchronization

Objective: To synchronize a master server program with multiple subservers

1. Configure the synchronization Source

Install rsync: yum-y install rsync xinetd

Enable rsync: vim/etc/xinetd. d/rsync to change disable = yes to disable = no

Configuration: vim/etc/rsyncd. conf

# Synchronization source ID, which can be changed at will
[Site]
# Program path
Path =/home/backup
# Synchronized hosts
Hosts allow = 192.168.1.14
Hosts deny = *
List = true
Uid = root
Gid = root
Read only = false

2. Configure the synchronization server

Install rsync, set the Filter list, and run the following command:

Rsync-avz -- delete -- exclude-from =/etc/rsync_exclude.lst/var/www/html/server_ip: site

Server_ip is the Server IP address or domain name, and the site is the synchronization source ID.

In addition, set the timing script. In this way, the station group of the synchronization server can be synchronized from the master server rsync in a timely manner.
