主要內(nèi)容：

1.Sersync是什么

2.準(zhǔn)備環(huán)境

3.Sersync的使用

4.Sersync的配置

一、Sersync是什么

實(shí)時(shí)同步:sersync/inotify
sersync:整合inotify和rsync命令
監(jiān)控文件/目錄是否有變化（增刪改）

二、準(zhǔn)備環(huán)境

web01
nfs01
backup

三、sersync的使用

服務(wù)端：

1.準(zhǔn)備rsync服務(wù)

（1）sersync 利用到了rsync的守護(hù)進(jìn)程模式
（2）backup上面的共享目錄為 /nfsbackup

2.準(zhǔn)備好sersync

（1）上傳 解壓 加權(quán)限

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 /upload && rsync -az -R --delete ./ rsync_backup@172.16.1.41::nfsbackup --password-file=/etc/rsync.password >/dev/null 2>&1 
run the sersync:
