This article is part of the system build

Hardware environment:

All IBM3650M4 servers Two nginx_proxies, two web_servers, nfs, DB, backup

System environment:

Operating system is Centos 6.5, rsync version 3.0.6

Purpose: Deploy the rsync --daemon process for backup files

Server:

1. Installation (PC/Server requires rsync command)

The system comes with rsync command. If you need to install it, please use the following command:

yum install -y rsync

2. Create rsync --daemon process user

useradd rsync -s /sbin/nologin -M

3. Create the folder backup used by the rsync --daemon process, and specify that the file belongs to the primary group as the rsync --daemon process user. (Because it is a backup service, I use backup, which can be specified in the configuration file)

mkdir /backup

chown -R rsync.rsync

4, Create rsync configuration file,/etc/rsyncd.config

vim /etc/rsyncd.config

uid = rsync gid = rsyncuse chroot = false max connections = 6 strict modes =yes#port = 873 pid file = /var/run/rsyncd.pidlock file = /var/run/rsync.lock log file = /var/log/rsyncd.log[backup] path = /backup/comment = This is a all host backup ignore errorsread only = falselist = falseauth users = rsync_backupsecrets file = /etc/rsync.passwordhosts allow = 172.16.100.0/24hosts deny = 0.0.0.0/0log file = /var/log/backup_rsyncd.log

Note: Log file contains two entries, but in different locations. Log file is written outside and inside the [backup] module, and the logs recorded are different; another problem is that when log file is written outside the module, rsync --daemon will create rsync.log file when it starts, and record rsync startup log, otherwise it will not. Logs are generated only when files are synchronized.

5. Create the "auth_users user" and password used for authentication, and modify the permission to 600.

vim /etc/rsync.password

rsync_backup:111111

chmod 600 /etc/rsync.passwd

Start rsync --daemon

rsync --daemon

Client:

1. Create the password file required for rsync authentication, and modify the permission to 600.

vim /etc/rsync.password

11111

chmod 600 /etc/rsync.password

2. Start synchronization command and specify password file

rsync -az file rsync_backup@172.16.100.6::backup --password-file=/etc/rsync.password
