Rsync+unison双向文件同步

Posted 2020-09-15 MoStart

1.配置RSYNC服务器的同步源：

• 基于SSH同步源　　
  • rsync -avz /server/rsyncd/*  chen@172.16.23.204:/client/rsyncd
• 基于RSYNC同步源
  • /etc/rsyncd.conf

    • address = 172.16.23.203
      port 873
      pid file = /var/run/rsyncd.pid
      lock file = /var/run/rsync.lock
      log file = /var/log/rsyncd.log
      read only = false
      auth users = chen
      secrets file = /etc/rsync_user.db
      [share]
      comment = soft
      path=/server/rsyncd

  • /etc/rsyncd_user.db
    • 文件的权限必须是600

      chen:123456

    上行同步的时候：nobody必须有权限（setfacl -m u：nobody：rwx  /client/rsyncd）
    • 　rsyncd -avz chen@172.16.23.203::share  /client/rsyncd/ 
    •    rsyncd -avz  rsyncd://chen@172.16.23.203/share /client/rsyncd
• 免验证登录
  • 基于ssh秘钥对登录
  • 密钥对ssh-keygen -t rsa
  • 传到对端：ssh-copy-id 172.16.23.204
  • 基于RSYNCD系统变量
    • RSYNC_PASSWORD=123456

2.inotify+rsyncd

• 服务端建立脚本

  • #!/bin/bash
    a="/usr/local/bin/inotifywait -mrq -e create,delete /server/rsyncd"
    b="/usr/bin/rsync -avz /server/rsyncd/* 172.16.23.204:/client/rsyncd"
    $a | while read diretory event file
    do
            $b
    done

　　　　　　执行 bash a.sh & 放到后台执行

3.inotify+unison

　　安装软件：inotify-tools-3.14.tar.gz   ocaml-3.10.0.tar.gz  unison-2.13.16.tar.gz

• • tar zxvf inotify-tools-3.14.tar.gz 
    • ./configure && make && make install
  • tar -zxvf ocaml-3.10.0.tar.gz  
    • ./configure
    • make world opt
    • make install
  • tar zxvf   unison-2.13.16.tar.gz
    • cd unison-2.13
    • make UISTYLE=text THREADS=true STATIC=true
    • cp unison /usr/local/bin
  • 建立脚本

    • #!/bin/bash
      a="/usr/local/bin/inotifywait -mrq -e create,delete /server1"
      b="/usr/bin/unison -batch /server1  ssh://172.16.23.204//server2"
      $a | while read diretory event file
      do
              $b
      done
