How to configure and use rsync in linux

Article Title: rsync configuration and usage tutorial in linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

The testing environment in this test uses Redhat AS4 (two servers, one server and one client)

Ip address of the rsync server: 192.168.23.102

Ip address of the rsync client: 192.168.23.100

-----------------------------------------------

Configure the server first:

1. Install the rsync package

[Root @ rhel403 old] # rpm-q rsync

Rsync-2.6.3-1

2. rsync only uses one configuration file:/etc/rsyncd. conf.

[Root @ rhel403 old] # more/etc/rsyncd. conf

Uid = nobody

Gid = nobody

Max connections = 200

Timeout = 600

Use chroot = no

Read only = yes

Pid file =/var/run/rsyncd. pid

Host_allow = 192.168.23.100 // write the IP address of the client here

# Syslog facility = local7

# Log file =/var/log/rsyncd. log

# Rsync config

# The 'standard' things

[Rsync_gmmold] // defines the synchronization path (the client uses this keyword to link)

Path =/gmm/old // path to be synchronized

Comment = gmmold // Annotation

3. Start the service

#/Usr/bin/rsync -- daemon

4. Add to boot

Echo "/usr/bin/rsync -- daemon">/etc/rc. local

5. Start during rsync check

# Ps-ef | grep rsync

6. Stop the service

# Kill 'cat/var/run/rsyncd. Pi'

---------------------------------------------------------------------------

The configuration of the client is as follows:

1. Install the rsync package

[Root @ rhel403 old] # rpm-q rsync

Rsync-2.6.3-1

2. synchronize with the server:

# Rsync-auqz 192.168.23.102: rsync_gmmold/tmp/old
