Ubuntu uses Rsync+inotify-tools to implement file synchronization two

In the previous article, I talked about how to use rsync and Inotify-tools in Ubuntu to sync files between two Ubuntu servers. Now more into

One step, false with A1,a2,a3,a4 four servers, their sync folder set to/data, when any one of the machines on the changes in the file, can automatically

Sync up to the other machines. This is the subject to be discussed in this article.

First you need to set up each machine to become an rsync server, and each machine will act as a rync from the machine and run Inotify-tools. So, every machine

The device must have an rsync two key files, one as the host set the username: password format of the secret key file, the other as a machine only secret

Code of the secret key file. The IP for four machines is:

a1:192.168.1.10       
a2:192.168.1.20     
a3:192.168.1.30     
a4:192.168.1.40  

A1 's/etc/rsyncd.conf file:

# sample rsyncd.conf configuration file # GLOBAL OPTIONS #motd FILE=/ETC/MOTD log file=/var/log/rsyncd # for PID file, D
o not use/var/run/rsync.pid If # and are going to run rsync out of the init.d script.
 # The INIT.D script does its own PID file handling, # So omit the ' PID file ' line completely in.

The configuration files of the other 3 machines are different from the A1 in the configuration file host allow to the corresponding other three machines IP.

A1 's rsyn.sh file:

Src=/data
dst[0]=lzj@192.168.1.20::ftp

exit 0

Let the rsyn.sh script run in the background:

chmod +x rsync.sh
nohup bash rsyn.sh &
