确保rsync服务正确，c/s端
1.大前提Rsync Daemon服务正确 [root@nfs ~]# rsync -avz --delete /data/ rsync_backup@10.0.0.40::backup
确保当前客户端机器，是否支持Inotify
[root@nfs ~]# ls /proc/sys/fs/inotify/
max_queued_events max_user_instances max_user_watches
Sersync安装
1.资料参考地址 谷歌项目地址：https://code.google.com/archive/p/sersync/ 64位下载地址：https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/sersync/sersync2.5.4_64bit_binary_stable_final.tar.gz 32位下载地址：https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/sersync/sersync2.5_32bit_binary_stable_final.tar.gz 上不去google的可以直接wget我本地的包，这里只提供64位版本的：https://down.whsir.com/downloads/sersync2.5.4_64bit_binary_stable_final.tar.gz 压缩包里面有两个文件confxml.xml sersync2 sersync2 这个是sersync主程序 confxml.xml 这个是sersync配置文件 2.下载获取sersync软件包，上传至linux [root@nfs ~]# tar -zxvf sersync2.5.4_64bit_binary_stable_final.tar.gz -C sersync2.5.4 GNU-Linux-x86/ GNU-Linux-x86/sersync2 GNU-Linux-x86/confxml.xml 3.检查sersync文件执行权限 [root@nfs GNU-Linux-x86]# ll total 1772 -rwxr-xr-x. 1 root root 2214 Oct 25 2011 confxml.xml -rwxr-xr-x. 1 root root 1810128 Oct 26 2011 sersync2

Sersync部署应用
1.使用绝对路径查看sersync命令帮助 [root@nfs ~]# ~/sersync2.5.4/GNU-Linux-x86/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 ________________________________________________________________ 2.生成sersync命令快捷键 [root@nfs ~]# ln -s /sersync2.5.4/sersync2 /usr/local/bin/ [root@nfs ~]# sersync2 -h
这里有个坑：配置临时环境变量，为什么sersync命令不生效
sersync软件服务开启，命令如下：
[root@nfs ~]# sersync -r -d -o /sersync2.5.4/ confxml.xml sersync [root@nfs ~]# sersync -r -d -o /sersync2.5.4/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: -r rsync all the local files to the remote servers before the sersync work option: -d run as a daemon option: -o config xml name： /sersync2.5.4/confxml.xml daemon thread num: 10 parse xml config file host ip : localhost host port: 8008 daemon start，sersync run behind the console use rsync password-file : user is rsync_backup passwordfile is /etc/rsync.password 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 -artuz -R --delete ./ rsync_backup@10.0.0.40::backup --password-file=/etc/rsync.password >/dev/null 2>&1 run the sersync: watch path is: /data
