1.下载安装inotify-tools
[root@nfs /usr/local]# yum install -y inotify-tools2.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.gz3.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 sersync4.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
<fileSystem xfs="true"/> #Centos7默认是xfs文件系统，要开启
<filter start="false"> #文件排除
<exclude expression="(.*).svn"></exclude>
<exclude expression="(.*).gz"></exclude>
<exclude expression="^info/*"></exclude>
<exclude expression="^static/*"></exclude>
</filter>
<inotify> #文件变化类型
<delete start="true"/>
<createFolder start="true"/>
<createFile start="true"/>
<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
<remote ip="172.16.1.41" name="data"/> #变化后传到的目的模块
<!--<remote ip="192.168.8.39" name="tongbu"/>-->
<!--<remote ip="192.168.8.40" name="tongbu"/>-->
</localpath>
<rsync>
<commonParams params="-az"/> #rsync执行时加的参数
<auth start="true" users="rsync_backup" passwordfile="/etc/password"/> #虚拟用户和虚拟用户的密码
<userDefinedPort start="false" port="874"/><!-- port=874 -->
<timeout start="true" time="100"/><!-- timeout=100 --> #超时时间
<ssh start="false"/> #ssh协议是否开启，走rsync协议，所以不需要
</rsync>
<failLog path="/tmp/rsync_fail_log.sh" timeToExecute="60"/><!--default every 60mins execute once--> #错误日志地址
<crontab start="false" schedule="600"><!--600mins-->
<crontabfilter start="false">
<exclude expression="*.php"></exclude>
<exclude expression="info/*"></exclude>
</crontabfilter>
</crontab>
<plugin start="false" name="command"/>
</sersync>
<plugin name="command">
<filter start="false">
</filter>
<plugin name="socket">
<localpath watch="/opt/tongbu">
<deshost ip="192.168.138.20" port="8009"/>
</localpath>
</plugin>
<plugin name="refreshCDN">
<localpath watch="/data0/htdocs/cms.xoyo.com/site/">
<cdninfo domainname="ccms.chinacache.com" port="80" username="xxxx" passwd="xxxx"/>
<sendurl base="http://pic.xoyo.com/cms"/>
<regexurl regex="false" match="cms.xoyo.com/site([/a-zA-Z0-9]*).xoyo.com/images"/>
</localpath>
</plugin>
</head>
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: /data7.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 11:34 44_lhd_nfs.txt8.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
