ubuntu下使用rsync+inotify-tools实现文件同步之二

     在前面一篇文章讲了怎么在ubuntu下使用rsync和inotify-tools来进行俩台ubuntu服务器之间的文件同步。现在更进

一步，假设有A1,A2,A3,A4四台服务器，它们的同步文件夹设置为/data,当其中任意一台机器上文件变化时，能够自动

同步到其它机器上去。这个就是本文要讨论的主题。

    首先需要设置每一台机器都成为rsync服务器，并且每一台机器都将作为rync从机并运行inotify-tools。所以，每台机

器上面都要有一个rsync俩个秘钥文件，一个作为主机设置了 用户名：密码 格式的秘钥文件，另外一个作为从机只有密

码的秘钥文件。设四台机器的ip分别为：

A1:192.168.1.10       
A2:192.168.1.20     
A3:192.168.1.30     
A4:192.168.1.40  

A1的/etc/rsyncd.conf文件：

# sample rsyncd.conf configuration file

# GLOBAL OPTIONS

#motd file=/etc/motd
log file=/var/log/rsyncd
# for pid file, do not use /var/run/rsync.pid if
# you 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 that case.
 pid file=/var/run/rsyncd.pid
syslog facility=daemon
#socket options=

# MODULE OPTIONS

[ftp]

	comment = public archive
	path = /data
	use chroot = no
#	max connections=10
	lock file = /var/lock/rsyncd
# the default for read only is yes...
	read only = no
	list = yes
	uid = root
	gid = root
#	exclude = 
#	exclude from = 
#	include =
#	include from =
	auth users = lzj 
	secrets file = /etc/rsyncd.secrets
	strict modes = yes
	hosts allow = 192.168.1.20 192.168.1.30 192.168.1.40
#	hosts deny =
	ignore errors = yes
	ignore nonreadable = yes
	transfer logging = no
#	log format = %t: host %h (%a) %o %f (%l bytes). Total %b bytes.
	timeout = 600
	refuse options = checksum dry-run
	dont compress = *.gz *.tgz *.zip *.z *.rpm *.deb *.iso *.bz2 *.tbz

A1的 /etc/rsyncd.secrets文件：

lzj:123

A1的/etc/rsync.pass文件：

123

其它3台机器的配置文件跟A1不同的地方就是在配置文件的host allow修改成对应的其它三台机器的ip。

A1的rsyn.sh文件：

src=/data
dst[0][email protected]::ftp
dst[1][email protected]::ftp
dst[2][email protected]::ftp
 
/usr/bin/inotifywait -mr --timefmt '%d/%m/%y %H:%M' --format '%T %w%f%e' -e modify,delete,create,attrib $src | while read files
        do
       		for i in ${dst[@]}
		do
		rsync -vzrtopg --delete  --progress --password-file=/etc/rsync.pass $src $i
		echo $i
		done
        done
exit 0

让rsyn.sh脚本在后台运行：

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