Set up rsync remote file synchronization service under Centos6.5

Set up rsync remote file synchronization service under Centos6.5

I. Server Installation

1. System Environment

Server: centos6.5 Factory environment (set by default during system installation), IP: 192.168.10.185

Client: Remote logon terminal xshell5 or securecrt (please check the installation and usage ),

IP: 192.168.10.186

2. Install Rsync

Log on to the system 192.168.10.185 through the terminal (xshell here)

Rpm-qa | grep rsync * // check whether the service is currently installed. if the version is low, run

Rpm-e rsync * // uninstall the software

Installation Method 1:

Run yum-y install rsync

Rpm-qa | grep rsync * // run this statement to view information about the installed software.

Rsync. x86_64. 0.6-12. el6

Installation Method 2:

Download the source code package from the rsync Website:Http://rsync.samba.org/Pack name: rsync-3.1.1.tar.gz

Yum-y install lrzsz // enter rz in the command line: Upload the downloaded source code package to the server.

Tar zxf rsync-3.1.1.tar.gz

Cd rsync-3.1.1

./Configure -- prefix =/app

Make

Make install

Start File Location:/app/bin/rsync

3. Create an rsync configuration file (not available by default)

Create rsyncd. conf under/etc/respectively (service configuration file)

Rsync. passwd (stores the account and password used by the client to log on to the rsync Service)

Rsyncd. motd)

######################################## ######################################## ##########

Vim/etc/rsyncd. conf // create a service configuration file

Uid = root

Gid = root

Port = 873 // specify the access port. The default value is 873.

Hosts allow = Client IP address // the client to be accessed

# Hosts deny =

# User chroot =

# Max connections =

# Timeout =

[Backup]

Path =/bak // Note: If this directory does not exist, do not forget to create it!

Comment = rsync files

Ignore erros

Read only = no

List = yes

Auth usres = rsync // The account used for synchronization verification. If not, it is anonymous synchronization. If the client does not have a user name, it can also be synchronized.

Secrets file =/etc/rsync. passwd // The place where the authentication file is stored

######################################## ######################################## #########

Vim/etc/rsync. passwd // create an authentication File

Syj: syj2015 // This format is required. The rsync account is the auth users in the service configuration file. The two are consistent and the password is customized.

Chmod 600/etc/rsync. passwd // change the File Permission to read-only by the owner

4. Firewall settings

Iptables-a input-p tcp -- dport 873-j ACCEPT // the server can be accessed locally and can be tested first.

Iptables-I INPUT-p tcp -- dport 873-j ACCEPT // The client can access

5. Start the rsync Service

/Usr/bin/rsync -- daemon

6. Check whether the service is started.

[Root @ localhost ~] # Lsof-I: 873

Command pid user fd type device size/OFF NODE NAME

Rsync 28055 root 3u IPv4 81353 0t0 TCP *: rsync (LISTEN)

Rsync 28055 root 5u IPv6 81354 0t0 TCP *: rsync (LISTEN)

In this case, the service is enabled.

Ii. Client installation

1. Execute yum-y install rsync like the Server installation.

2. Start rsync and run/usr/bin/rsync -- daemon.

3. After step 3 is completed, "Failed to parse config file:/etc/rsyncd. conf" appears ",

Solution: Create an empty configuration file vim/etc/rsyncd. conf and execute Step 1 again.

Iii. instance (Server IP: 192.168.10.185, Client IP: 192.168.10.186)

1. log on to the client and back up the content in the/bak folder on the server to the/imagefile on the client:

/App/bin/rsync-vzrtopg -- delete-- Progress rsync@192.168.10.185: bak/imagefile

2. log on to the client and back up the content in the client/imagefile folder to the server/bak:

/App/bin/rsync-vzrtopg -- delete -- progress/imagefile rsync@192.168.10.185: backup-- Password-file =/etc/secret. pas (password verification is automatically provided)
