lsyncd 本地双硬盘实时同步文件目录

lsyncd本地目录同步，有多种工作模式可以选择，本地目录cp，本地目录rsync，远程目录rsyncssh。本文内容为本地目录的同步配置

AkkunYo需求：本服务器有kod网盘，同时对于网盘资料进行多硬盘同步备份

源文件夹/var/www/html/

备份位置/data/html

#### 1.手动或定时同步

```sh

[root@akkun ~]# yum install rsync -y

# 默认增量更新添加--detele表示同步删除增加文件

[root@akkun ~]# rsync -avz --delete /var/www/html/ /data/html/

#定时任务

[root@akkun ~]# echo "*/5 * * * * rsync -avz --delete /var/www/html/ /data/html/ >/dev/null 2>&1" > /var/spool/cron/root

#去除定时任务的mail邮件提醒

[root@akkun ~]# echo "unset MAILCHECK" >> /etc/profile

```

#### 2.自动lsyncd监控同步

```sh

[root@akkun ~]# yum install lua lua-devel

[root@akkun ~]# rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

[root@akkun ~]# yum install lsyncd rsync -y

#开启lsyncd服务

[root@akkun ~]# /etc/init.d/lsyncd start

#设置lsyncd服务自启动

[root@akkun ~]# chkconfig lsyncd on

#配置conf

[root@akkun ~]# cat > /etc/lsyncd.conf << EOF

----

-- User configuration file for lsyncd.

-- Simple example for default rsync, but executing moves through on the target.

-- create by sh

-- For more examples, see /usr/share/doc/lsyncd*/examples/

-- 本次启用II

-- I. 本地目录同步，direct：cp/rm/mv。适用：500+万文件，变动不大

-- sync {

-- default.direct,

-- source = "/tmp/src",

-- target = "/tmp/dest",

-- delay = 1

-- maxProcesses = 1

-- }

-- II. 本地目录同步，rsync模式：rsync

sync {

default.rsync,

source = "/var/www/html/",

target = "/data/html/",

excludeFrom = "/etc/rsync_exclude.lst",

-- exclude = "a.txt",

rsync = {

binary = "/usr/bin/rsync",

archive = true,

compress = false,

-- bwlimit = 2000

}
