lsync+rsync 实时同步(ubuntu16.04系统)

1.同步端需要安装 lsync/rsync
apt-get install lsyncd rsync
2.生成ssh公钥，粘贴到目标机器里面
3.创建配置文件
mkdir /etc/lsyncd
cat /etc/lsyncd/lsyncd.conf.lua
sync {
default.rsyncssh,
source = "/var/www/html",
host = "172.16.80.26",
targetdir = "/var/www/html",
-- excludeFrom = "/etc/rsyncd.d/rsync_exclude.lst",
-- maxDelays = 5,
delay = 0,
-- init = false,
rsync = {
binary = "/usr/bin/rsync",
archive = true,
compress = true,
verbose = true,
_extra = {"--bwlimit=2000"},
},
ssh = {
port = 22
}
}

4.启动lsyncd

/etc/init.d/lsyncd start

-- # 监测本地目录发生变化就用touch更新一下mtime时间。

    maxDelays = 5,

        -- 如果要指定其它端口，请用上面的rsh
        }
    }
-- # 远程目录同步，rsync模式 + rsyncssh，效果与上面相同
sync {
    default.rsyncssh,
    source    = "/tmp/src2",
    host      = "172.29.88.223",
    targetdir = "/remote/dir",
