Centos系统使用rsyn实现双主机附件目录实时同步

A主机:192.168.2.18，B主机：192.168.2.20；目录：/data/{dira,dirb}
数据同步os用户名：hhdb，A、B hhdb用户需要配置免密

1.安装rsyn\lsyncd

yum -y install rsync lsyncd

2.A服务器配置

2.1 /etc/lsyncd.conf

配置文件
vi /etc/lsyncd.conf

----
-- User configuration file for lsyncd.
--
-- Simple example for default rsync, but executing moves through on the target.
--
-- For more examples, see /usr/share/doc/lsyncd*/examples/
--
-- sync{default.rsyncssh, source="/var/www/html", host="localhost", targetdir="/tmp/htmlcopy/"}
settings {
    logfile      ="/var/log/lsyncdA.log",
    statusFile   ="/usr/local/lsyncdA.status",
    inotifyMode  = "CloseWrite",
    maxProcesses = 8,
    -- nodaemon =true,
    }

sync {
    default.rsync,
    source    = "/data/dira",
    target    = "rsync_backup@192.168.2.20::backup",
    rsync     = {
        binary    = "/usr/bin/rsync",
        password_file = "/etc/rsyncA.password",
        archive   = true,
        compress  = true,
        verbose   = true
        }
