Configure rsync to synchronize data to the Internet in CentOS5.6

I. requirement guard has a requirement to synchronize data from an intranet server to a server on the Internet, previously, I used real-time synchronization updates implemented by rsync + in‑tool + ssh. I was on a business trip in Dongguan a few days ago, the developer called me and said that the data on the two servers was not synchronized. I went up and checked it again. The system account used to synchronize data was changed by my colleagues in Beijing, ssh password-free login failed, so the data cannot be synchronized. later I thought it would be true to have a single user on the system for data synchronization.

I. requirements

The guard has a requirement to synchronize data from an intranet server to an Internet server. Previously, I used rsync + InSync-tool + ssh for real-time synchronization updates, I was on a business trip in Dongguan a few days ago. the developer called me and said that the data on the two servers was not synchronized. I went up and checked it again, the system account used to synchronize data was modified by colleagues in Beijing. ssh password-free login failed, so data cannot be synchronized, later, I thought that there was indeed a security risk when a single user was opened in the system to synchronize data. I had a specific communication with developers, and the data synchronization of this project was not so necessary to be synchronized in real time, so now I want to use rsync for single synchronization. the specific steps are as follows:

II. environment

Intranet: 10.20.220.247

Synchronization directory 1:/data/Dynamic data/softmgr-v3/static-file/update

Synchronization directory 2:/data/Dynamic data/softmgr-v3/static-file/v1_0

Internet: 114.112.36.X

Synchronization directory 1:/data/apps/ksoftmgr/ksafe/client/update

Synchronization directory 2:/data/apps/ksoftmgr/ksafe/client/v1_0

III. installation and configuration

1. server (114.112.36.69)

A. [root @ localhost ~] # Yum-y install rsync xinetd

B. [root @ localhost ~] # Vi/etc/xinetd. d/rsync

Change disable = no to yes

[Root @ localhost ~] #/Etc/init. d/xinetd start

C. write The rsync configuration file

[Root @ localhost ~] # Vi/etc/rsyncd. conf

Uid = root

Gid = root

Use chroot = no

Max connections = 10

Strict modes = yes

Pid file =/var/run/rsyncd. pid

Lock file =/var/run/rsync. lock

Log file =/var/log/rsyncd. log

 

[Update]

Path =/data/apps/ksoftmgr/ksafe/client/update

Comment = update file

Ignore errors

Read only = no

Write only = no

Hosts allow = 125.89.65.194

Hosts deny = *

Uid = root

Auth users = wcm

Secrets file =/etc/web. pass

 

[V1_0]

Path =/data/apps/ksoftmgr/ksafe/client/v1_0

Comment = v1_0 file

Ignore errors

Read only = no

Write only = no

Hosts allow = 125.89.65.194

Hosts deny = *

Uid = root

Auth users = wcm

Secrets file =/etc/web. pass

D. write a password file

[Root @ localhost ~] # Vi/etc/web. pass (format account: password)

Wcm: 8888888

[Root @ localhost ~] # Chown root: root/etc/web. pass

[Root @ localhost ~] # Chmod 600/etc/web. pass

E. start rsync.

[Root @ localhost ~] # Rsync -- daemon

[Root @ localhost ~] # Echo "rsync -- daemon">/etc/rc. local

2. client (10.20.220.247)

A. [root @ localhost ~] # Yum-y install rsync

B. write a password file

[Root @ localhost ~] # Vi/etc/web. pass (mainly: write the password of the account used for synchronization only)

8888888

[Root @ localhost ~] # Chown root: root/etc/web. pass

[Root @ localhost ~] # Chmod 600/etc/web. pass

C. write a crontab and synchronize it once every minute.

[Root @ localhost v1_0] # crontab-e

*/1 ***/usr/bin/rsync-avz -- progress -- delete/data/parse data/softmgr-v3/static-file/update/wcm@114.112.36.x :: update -- password-file =/etc/web. pass

*/1 */usr/bin/rsync-avz -- progress -- delete/data/parse data/softmgr-v3/static-file/v1_0/wcm@114.112.36.X :: v1_0 -- password-file =/etc/web. pass

IV. test

Delete or create a file under intranet update and v1_0 to check whether the corresponding operation is performed on the machine on the Internet. If yes, it means OK. I must scatter it, online Non-synchronization is a tragedy.
