This chapter mainly explains the realization of fast, safe and efficient remote backup.

Experimental environment: server A 192.168.1.10 client B 192.168.1.20

First, install rsync yum-y install rsync*

Create a new configuration file vi / etc/rsyncd.conf

Uid = nobody

Gid = nobody

Use chroot = yes

Address = 192.168.1.10

Port 873

Log file = / var/log/rsyncd.log

Pid file = / var/run/rsyncd.pid

Hosts allow = 192.168.1.0 Compact 24

[yy]

Path = / var/www/html

Comment = ccccccccccccc

Read only = yes

Dont compress = * .gz * .bz2

Auth users = bin

Secrets file = / etc/rsyncd_users.db

Note: if you use anonymous synchronization, just remove the auth users and secrets file configuration records.

Second, create a password authentication file vi / etc/rsyncd_users.db

Bin:123

Save exit

Modify password file permissions chmod 600 / etc/rsyncd_users.db

Third, start rsync rsync-- daemon ps-ef | grep rsync to view the process.

If you want to end the process kill process number kill

1. Use rsync local backup to back up the file / etc/fastab to / tmp

Rsync-rl / etc/fastab / tmp/

2. To use the client for remote backup, first configure the server firewall iptables-I INPUT-p tcp-- dport 873-j ACCEPT

Service iptables save Save Firewall

Fourth, client configuration

1. Create the test directory mkdir / rsync

two。 Synchronize rsync shared directories

# rsync bin@192.168.1.10::yy / / Browse sharing

Vim / root/rsync_pass / / set password file

123 / / only need to write the login user password, which should be consistent with the password set by the server

Chmod 60000 / root/rsync_pass / / error will be reported if permissions are not modified

Rsync-az-- password-file=/root/rsync_pass bin@192.168.1.10::yy / rsync / / synchronization

3. Put rsync into crontab scheduled tasks and synchronize once a day

# crontab-e

0 5 * / usr/bin/rsync-a-password-file=/root/rsync_pass bin@192.168.1.10::yy / rsync
