注意：include和exclude使用的目录，均为path定义的相对路径
环境：两台虚拟机128和130，在128上配置RsyncServer；130上做同步测试
rsync服务配置文件
vim /etc/rsyncd.conf
uid = nobody
gid = nobody
use chroot = no
max connections = 4
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
[nagios-53]
path = /opt
include = db1/
exclude = db1/1.log
read only = true
hosts allow = 192.168.128.130
hosts deny = 0.0.0.0/0
auth users = backup
secrets file = /etc/rsyncd/.rsync.pas
在128的/opt目录下有db1，db2，db3三个目录，里面分别有1.log、2.log、3.log文件
每次测试只修改配置rsync的配置文件，不需要重启rsync服务。
测试开始：
第一次：同步db1
include = db1/
exclude = db2/ db3/
同步命令
rsync -tvzrp --progress --password-file=/etc/.rsync [email protected]::nagios-53 /home
同步结果：
receiving file list ...
3 files to consider
./
db1/
db1/1.log
0 100% 0.00kB/s 0:00:00 (xfer#1, to-check=0/3)
sent 140 bytes received 186 bytes 652.00 bytes/sec
total size is 0 speedup is 0.00
第二次：同步db1和db2
include = db1/ db2/
exclude = db3/
同步命令：
rsync -tvzrp --progress --password-file=/etc/.rsync [email protected]::nagios-53 /home
同步结果：
receiving file list ...
5 files to consider
./
db1/
db1/1.log
0 100% 0.00kB/s 0:00:00 (xfer#1, to-check=2/5)
db2/
db2/2.log

total size is 0 speedup is 0.00
第三次：只同步db1
include = db1/
exclude = *
同步命令：
rsync -tvzrp --progress --password-file=/etc/.rsync [email protected]::nagios-53 /home
同步结果：
receiving file list ...
2 files to consider
./
db1/
sent 118 bytes received 126 bytes 488.00 bytes/sec
total size is 0 speedup is 0.00
第四次：
include = db1/
exclude = db1/1.log
同步命令：
rsync -tvzrp --progress --password-file=/etc/.rsync [email protected]::nagios-53 /home
同步结果：
receiving file list ...
6 files to consider
./
db1/
db2/
db2/2.log

第五次：
include = db1/
#exclude = db1/1.log
同步命令：
rsync -tvzrp --progress --password-file=/etc/.rsync [email protected]::nagios-53 /home
同步结果：

第六次：
#include = db1/
exclude = db1/1.log db2/ db3/
同步命令：
rsync -tvzrp --progress --password-file=/etc/.rsync [email protected]::nagios-53 /home
