- 1）确保远程数据传输服务部署完成
[root@nfs01 ~]$rsync -avz /data/ rsync_backup@172.16.1.41::backup --password-file=/etc/rsync.password
- 2）检查当前系统是否支持inotify
uname -r
#是否存在下面三个文件
[root@nfs01 ~]$ll /proc/sys/fs/inotify/ total 0 -rw-r--r-- 1 root root 0 Nov 14 21:28 max_queued_events -rw-r--r-- 1 root root 0 Nov 14 21:28 max_user_instances -rw-r--r-- 1 root root 0 Nov 14 21:28 max_user_watches
- 3）在nfs01上安装配置sersync
mkdir /server/tools cd /server/tools/ #项目为空，下载不能用 wget https://github.com/wsgzao/sersync/blob/master/sersync2.5.4_64bit_binary_stable_final.tar.gz 提供其他两个版本下载 https://www.shnne.com/zb_users/upload/2022/11/sersync2.5.4_64bit_binary_stable_final.tar.gz 老男孩修改版 https://www.shnne.com/zb_users/upload/2022/11/sersync_oldboy_64bit_20160928.tar.gz
- 4）解压配置
tar xf sersync_oldboy_64bit_20160928.tar.gz mv sersync /application [root@nfs01 tools]$tree /application application/ └── sersync ├── bin │ └── sersync ├── conf │ ├── confxml.xml │ └── confxml.xml.ori ├── logs │ └── rsync_fail_log.sh └── readme.txt 4 directories, 5 files
- 5）配置文件讲解
#完成监控配置 inotifywait -mrq --format '%w%f' -e createFolder,close_write,delete,moveFrom,moveTo /data #完整命令拼接 rsync -avz /data/ rsync_backup@172.16.1.41::backup --password-file=/etc/rsync.password
- 6）启动sersync
[root@nfs01 bin]$/application/sersync/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 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
#启动进程 [root@nfs01 bin]$/application/sersync/bin/sersync -r -d -o /application/sersync/conf/confxml.xml set the system param execute：echo 50000000 > /proc/sys/fs/inotify/max_user_watches execute：echo 327679 > /proc/sys/fs/inotify/max_queued_events parse the command param option: -r rsync all the local files to the remote servers before the sersync work option: -d run as a daemon option: -o config xml name： /application/sersync/conf/confxml.xml daemon thread num: 10 parse xml config file host ip : localhost host port: 8008 daemon start，sersync run behind the console use rsync password-file : user is rsync_backup passwordfile is /etc/rsync.password config xml parse success please set /etc/rsyncd.conf max connections=0 Manually sersync working thread 12 = 1(primary thread) + 1(fail retry thread) + 10(daemon sub threads) Max threads numbers is: 32 = 12(Thread pool nums) + 20(Sub threads) please according your cpu ，use -n param to adjust the cpu rate ------------------------------------------ rsync the directory recursivly to the remote servers once working please wait... execute command: cd /data && rsync -artuz -R --delete ./ --timeout=100 rsync_backup@172.16.1.41::backup --password-file=/etc/rsync.password >/dev/null 2>&1 run the sersync: watch path is: /data
#结束进程 [root@nfs01 conf]$pkill sersync
- 7）配置systemd启动
[root@nfs01 /data]# tail -1 /etc/rc.local /application/sersync/bin/sersync -d
参考配置：systemctl start sersync启动方案
