Synchronizes files and directories by rsync

Synchronizes files and directories from one location to another location by rsync.

The example below is for automatical settings.

Copy files and directories in /data/proclog/ouxingning on a HostA[192.168.201.1] to in /data/ouxingning/backup on HostB[192.168.201.2].

1) Configure on Destination Host

yum -y install rsync xinetd

[root@ouxingning-5320-007 ~]# vi /etc/xinetd.d/rsync

# default: off
# description: The rsync server is a good addition to an ftp server, as it \
#       allows crc checksumming etc.
service rsync
{
        disable = no  # yes change to no
        flags           = IPv6
        socket_type     = stream
        wait            = no
        user            = root
        server          = /usr/bin/rsync
        server_args     = --daemon
        log_on_failure  += USERID
}

[root@ouxingning-5320-007 ~]# /etc/rc.d/init.d/xinetd start
正在启动 xinetd：                                          [确定]
[root@ouxingning-5320-007 ~]# chkconfig xinetd on

[root@ouxingning-5320-007 ~]# mkdir -p /data/ouxingning/backup

[root@ouxingning-5320-007~]# vi /etc/rsyncd.conf

# indicates the source host, any name you like
[backuplog]

# destination directory
path = /data/ouxingning/backup

# hosts you allow to copy (specify source host)
hosts allow = 192.168.201.1
hosts deny = *
list = true
uid = root
gid = root
read only = false

# specifie the name of a file that contains the username:password pairs
secrets file = /etc/rsyncd.secrets

vi /etc/rsyncd.secrets

root:123456

chmod 600 /etc/rsyncd.secrets

 

2) Configure on Source Host

[root@www ~]# yum -y install rsync
[root@www ~]# vi /etc/rsync_exclude.lst
# specify files or directories you'd like to exclude to copy
test
test.txt

 

3) It's OK, Execute rsync on Source Host like follows

[root@www ~]# rsync -avz --delete --exclude-from=/etc/rsync_exclude.lst /data/proclog/ouxingning/ 192.168.201.2::backuplog
# Add in cron if you'd like to run reguraly
[root@www ~]# crontab -e
# run at 2:00 AM in a day
00 02 * * * rsync -avz --delete --exclude-from=/etc/rsync_exclude.lst /data/proclog/ouxingning/ 192.168.201.2::backuplog

 

ps:

vi /etc/sysconf/selinx

setenforce 0  

#shell: setenforce 0
