sersync实践：
1）客户端推送成功

rsync -az /data [email protected]::backup

2)部署sersync服务（NFS）

[root@nfs01 /]# cd /server/tools/
[root@nfs01 /server/tools]#wget https://github.com/wsgzao/sersync/blob/master/sersync2.5.4_64bit_binary_stable_final.tar.gz
[root@nfs01 /server/tools]# ls
sersync2.5.4_64bit_binary_stable_final.tar.gz
[root@nfs01 /server/tools]# mkdir /application -p
[root@nfs01 /server/tools]# mv application/sersync /application/
[root@nfs01 /server/tools]# tree /application/
/application/
└── sersync
    ├── bin
    │   └── sersync
    ├── conf
    │   ├── confxml.xml
    │   └── confxml.xml.ori
    ├── logs
    │   └── rsync_fail_log.sh
    └── readme.txt

4 directories, 5 files

[root@nfs01 /server/tools]# cd /application/sersync/
[root@nfs01 /application/sersync]# ls
bin  conf  logs  readme.txt
[root@nfs01 /application/sersync]# cd conf/
[root@nfs01 /application/sersync/conf]# ls
confxml.xml  confxml.xml.ori

3)sersync配置文件：干两件事：

1）完成监控配置：

inotifywait -mrq --format '%w%f' -e createFolder,close_write,delete,moveFrom,moveTo /data
2）完整命令拼接：
rsync -az /data --timeout=100 [email protected]::backup

4)修改配置

[root@nfs01 /application/sersync/conf]# vim confxml.xml
        
        
        
    
    
        
        
        
        
        
        
        
        
    

    
        
            
            
            
            
"confxml.xml" 67L, 2266C                                                        28,6-13       15%

5)启动服务

[root@nfs01 /application/sersync/conf]# ../bin/sersync -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
________________________________________________________________

[root@nfs01 /application/sersync/conf]# /application/sersync/bin/sersync -d -n 10 -o /application/sersync/conf/confxml.xml
最终
/application/sersync/bin/sersync -d
pkill sersync
二进制程序，不是yum安装的，所以不能systemctl start sersync

配置：systemctl start sersync启动方案

[root@nfs01 /data]# tail -1 /etc/rc.local
/application/sersync/bin/sersync -d

6)配置：systemctl start sersync启动方案
https://blog.51cto.com/oldboy/2155931

[root@nfs01 /application/sersync/conf]# vim /etc/rc.d/init.d/sersync
stop(){
    killall sersync 2>/dev/null
}
case "$1" in
    start)
        start
▽       ;;
    stop)
        stop
        ;;
    restart)
        stop
        sleep 2
        start
        ;;
    *)
        echo $"Usage:$0 {start|stop|restart}"
        exit 1
