使用sersync实现实时数据同步

男儿欲遂平生志，六经勤向窗前读。这篇文章主要讲述使用sersync实现实时数据同步相关的知识，希望能为你提供帮助。
一、概述sersync类似于inotify，同样用于监控，但它克服了inotify的缺点.sersync不仅可以实现实时同步，另外还自带crontab功能，只需在xml配置文件中开启，即也可以按要求隔一段时间整体同步一次，而无需再额外配置crontab功能。
二、实现sersync下载地址： https://code.google.com/archive/p/sersync/downloads
文件服务器端配置：将sersync文件上传至文件服务器上解压，并移动到/usr/local下

tar -xf sersync2.5.4_64bit_binary_stable_final.tar.gz mv GNU-Linux-x86 /usr/local/sersync

配置环境变量

echo \'PATH=/usr/local/sersync:$PATH\' > /etc/profile.d/sersync.sh source /etc/profile.d/sersync.sh

后面的操作都要依赖于rsync，需要确保文件服务器上已经安装rsync工具
配置连接密码文件

echo 123456 > /etc/rsync.pas chmod 600/etc/rsync.pas

配置文件

[root@localhost ~]# cat /etc/rsyncd.conf # /etc/rsyncd: configuration file for rsync daemon mode# See rsyncd.conf man page for more options.# configuration example: uid = root gid = root # use chroot = yes max connections = 0 pid file = /var/run/rsyncd.pid exclude = lost+found/ transfer logging = yes timeout = 900 reverse lookup = no [backup] path = /data/backup comment = backup dir read only = no auth users = rsyncuser secrets file = /etc/rsync.pas
