角色	IP1	IP2	主机名	安装软件
backup	10.0.0.41/24	172.16.1.41/24	backup	rsync
NFSserver	10.0.0.31/24	172.16.1.31/24	nfs	sersync

3.配置

3.1.3 修改配置文件

[root@nfs01 sersync]# vim confxml.xml
[root@nfs01 sersync]# grep -E "createFile|localpath watch|remote ip|commonParams params|auth start|users" confxml.xml<createFile start="true"/><localpath watch="/data"><remote ip="172.16.1.41" name="data"/><commonParams params="-avz"/><auth start="true" users="rsync_backup" passwordfile="/etc/rsync.pas"/>

3.1.4 创建密码文件并授权

[root@nfs01 sersync]# echo 123456 > /etc/rsync.pas
[root@nfs01 sersync]# chmod 600 /etc/rsync.pas
[root@nfs01 sersync]# ll -R /etc/rsync.pas 
-rw------- 1 root root 7 Jun 24 22:01 /etc/rsync.pas

3.1.5 启动sersync守护进程

[root@nfs01 sersync]# /sersync/sersync/sersync2 -dro /sersync/sersync/confxml.xml
set the system param
execute：echo 50000000 > /proc/sys/fs/inotify/max_user_watches
execute：echo 327679 > /proc/sys/fs/inotify/max_queued_events
parse the command param
option: -d 	run as a daemon
option: -r 	rsync all the local files to the remote servers before the sersync work
option: -o 	config xml name：  /sersync/sersync/confxml.xml
daemon thread num: 10
parse xml config file
host ip : localhost	host port: 8008
will ignore the inotify createFile event 
daemon start，sersync run behind the console 
use rsync password-file :
user is	rsync_backup
passwordfile is 	/etc/rsync.pas
config xml parse success
please set /etc/rsyncd.conf max connections=0 Manually
sersync working thread 12  = 1(primary thread) + 1(fail retry thread) + 10(daemon sub threads) 
Max threads numbers is: 22 = 12(Thread pool nums) + 10(Sub threads)
please according your cpu ，use -n param to adjust the cpu rate
------------------------------------------
rsync the directory recursivly to the remote servers once
working please wait...
execute command: cd /data && rsync -avz -R --delete ./ rsync_backup@172.16.1.41::data --password-file=/etc/rsync.pas >/dev/null 2>&1 
run the sersync: 
watch path is: /data

3.2 备份端

3.2.1 安装软件
