发布于 7 天前  25 次阅读


1.下载安装inotify-tools

[root@nfs /usr/local]# yum install -y inotify-tools

2.下载安装sersync

[root@nfs /usr/local]# wget https://github.com/wsgzao/sersync/blob/master/sersync2.5.4_64bit_binary_stable_final.tar.gz

3.解压sersync包

[root@nfs /usr/local]# tar xf sersync2.5.4_64bit_binary_stable_final.tar.gz
[root@nfs /usr/local]# mv GNU-Linux-x86 sersync

4.配置sersync

[root@nfs sersync]# cat confxml.xml

需要改的地方:
 12     <inotify>
 13         <delete start="true"/>
 14         <createFolder start="true"/>
 15         <createFile start="true"/>
 16         <closeWrite start="true"/>
 17         <moveFrom start="true"/>
 18         <moveTo start="true"/>
 19         <attrib start="true"/>
 20         <modify start="true"/>
 21     </inotify>

 23     <sersync>
 24         <localpath watch="/data">
 25             <remote ip="172.16.1.41" name="data"/>


 28         </localpath>
 29         <rsync>
 30             <commonParams params="-az"/>
 31             <auth start="true" users="rsync_backup" passwordfile="/etc/rsync.passwd"/>





所有配置:
<?xml version="1.0" encoding="ISO-8859-1"?>
<head version="2.5">
<host hostip="localhost" port="8008"></host>
<debug start="false"/>                                                          #调试模式

    <closeWrite start="true"/>
    <moveFrom start="true"/>
    <moveTo start="true"/>
    <attrib start="true"/>
    <modify start="true"/>
</inotify>

<sersync>
    <localpath watch="/data">                                                   #监控上面变化的目录

    <rsync>
        <commonParams params="-az"/>                                            #rsync执行时加的参数

5.查看sersync参数

[root@nfs /usr/local]# /usr/local/sersync/sersync2 -h
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
_______________________________________________________
参数-d:启用守护进程模式
参数-r:在监控前,将监控目录与远程主机用rsync命令推送一遍
c参数-n: 指定开启守护线程的数量,默认为10个
参数-o:指定配置文件,默认使用confxml.xml文件
参数-m:单独启用其他模块,使用 -m refreshCDN 开启刷新CDN模块
参数-m:单独启用其他模块,使用 -m socket 开启socket模块
参数-m:单独启用其他模块,使用 -m http 开启http模块
不加-m参数,则默认执行同步程序

6.启动sersync

[root@nfs /usr/local]# /usr/local/sersync/sersync2 -dro /usr/local/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:  /usr/local/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.passwd
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 -az -R --delete ./ rsync_backup@172.16.1.41::data --password-file=/etc/rsync.passwd >/dev/null 2>&1 
run the sersync: 
watch path is: /data

7.测试文件实时同步

[root@backup /data]# ll upload
total 16
-rw-r--r--. 1 www www 22 Sep  9 09:07 11_lhd_nfs.txt
-rw-r--r--. 1 www www 22 Sep  9 09:30 22_lhd_nfs.txt
-rw-r--r--. 1 www www 22 Sep  9 11:31 333_lhd_nfs.txt
-rw-r--r--. 1 www www 22 Sep  9 11:34 44_lhd_nfs.txt

8.监控多个目录实时同步

[root@nfs /usr/local/sersync]# cp confxml.xml confxml1.xml
[root@nfs /backup]# ps -ef | grep sersync
root       4321      1  0 12:05 ?        00:00:00 /usr/local/sersync/sersync2 -dro /usr/local/sersync/confxml.xml
root       4374      1  0 12:08 ?        00:00:00 /usr/local/sersync/sersync2 -dro /usr/local/sersync/confxml1.xml


十七岁那年你弯腰,时光不及你眉梢。
