Inotify+rsync同步web服务器

 

Inotify同步web服务器

一．Ssh生成密钥。

1. 执行ssh-keygen -t rsa命令,然后一路回车。

2.rsync -av ~/.ssh/id_rsa.pub    [email protected]:~/.ssh/authorized_keys #web真实机

3. rsync -av ~/.ssh/id_rsa.pub    [email protected]:~/.ssh/authorized_keys #web真实机

4.实现本机ssh登录web真实机不用密码。

二．安装inotify

1.yum install inotify-tools-3.13-1.i386.rpm

2.vim inotify.sh

#!/bin/sh

src=/var/www/html/ 

des=/var/www/html/   

dip1=192.168.2.6 

dip2=192.168.2.7       

/usr/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f' -e modify,delete,create,attrib ${src} | while read file

        do

            echo "${file} was rsynced to ${dip1}"

            rsync -avz --delete --progress ${src} root@${dip1}:${des} &&

            echo "${file} was rsynced to ${dip1}" >> /tmp/rsync.log 2>&1

            echo "------------------------------------" >> /tmp/rsync.log 2>&1

           

            echo "${file} was rsynced to ${dip2}"

           rsync -avz --delete --progress ${src} root@${dip2}:${des} &&

            echo "${file} was rsynced to ${dip2}" >> /tmp/rsync.log 2>&1

            echo "------------------------------------" >> /tmp/rsync.log 2>&1

        done

exit

                   3.sh inotify.sh &

三．测试，在本机的/var/www/html/中执行 echo “inotify test !” > index.html,然后在需要同步的两台主机的该目录下查看index.html是否有写入 “inotify test !”
