rsync 源码安装及使用

  • 卸载系统自带rsync

      # yum remove  rsync

  • 安装 下载最新源码包：https://rsync.samba.org/

      # tar -zxvf rsync-3.1.2.tar.gz  
  # cd rsync-3.1.2  
  # ./configure --prefix=/usr/local/rsync --disable-ipv6  
  #  make && make install  

  # ln -s /usr/local/rsync/bin/rsync /usr/local/bin/rsync

  • server端配置(172.18.1.13,文件备份端)

    • 创建服务端配置文件

        # vim /usr/local/rsync/rsyncd.conf  

    #pid文件
    pid file = /var/run/rsyncd.pid
    port = 873
    #启动用户
    uid = root
    #启动用户组
    gid = root
    use chroot = no
    #最大连接数
    max connections = 5
    timeout 600
    #指定lock文件
    lock file = /var/run/rsyncd.lock
    #日志文件
    log file = /var/run/rsyncd.log
    secrets file = /usr/local/rsync/rsyncd.secrets
    #指定欢迎消息文件
    motd file = /usr/local/rsync/rsyncd.motd

    [wateroa_code]
    path = /home/backup/code
    ignore errors
    read only = false
    list = false
    hosts allow = 172.18.1.12
    #hosts deny = 0.0.0.0/32
    auth users root
    comment = wateroa_code

    [wateroa_db]
    path = /home/backup/db
    ignore errors
    read only = false
    list = false
    hosts allow = 172.18.1.14
    #hosts deny = 0.0.0.0/32
    auth users root
    comment = wateroa_db

    • 创建服务端欢迎文件

        #vi /usr/local/rsync/rsyncd.motd  

  ++++++++++++++++++++++++++++++++++++  
  Wlecome to  rsync services         
  ++++++++++++++++++++++++++++++++++++

    • 指定rsync访问的密码（密码不需要和系统账号密码相同）

        # vi /usr/local/rsync/rsyncd.secrets    
  root:snow01@0256  
  //设置文件权限、所属用户
  # chmod 600 /usr/local/rsync/rsyncd.secrets  
  # chown root:root /usr/local/rsync/rsyncd.secrets
  //建立软链接
  ln -s /usr/local/rsync/rsyncd.conf /etc/rsyncd.conf  
  ln -s /usr/local/rsync/rsyncd.motd /etc/rsyncd.motd  
  ln -s /usr/local/rsync/rsyncd.secrets  /etc/rsyncd.secrets

    • 启动rsync

        # /usr/local/bin/rsync --daemon --config=/etc/rsyncd.conf
  # echo "/usr/local/bin/rsync --daemon --config=/etc/rsyncd.conf" >> /etc/rc.d/rc.local
  # cat /etc/rc.d/rc.local
      #!/bin/sh
      #  
      # This script will be executed *after* all the other init scripts.  
      # You can put your own initialization stuff in here if you don't  
      # want to do the full Sys V style init stuff.  
      /usr/local/bin/rsync --daemon --config=/etc/rsyncd.conf

  • 客户端服务器配置

    • 新建客户端密码文件(客户端不带用户名)

        #vim /usr/local/rsync/rsyncd.secrets
  snow01@0256
  # chmod 600 /usr/local/rsync/rsyncd.secrets

    • rsync命令常用参数

      • --delete 删除目标文件比源文件多余的文件
      • --progress 显示进度情况
      • --exclude 排除的文件(文件不会被同步)，可以写多个

    • 新建同步脚本（推）

        # vi /rsync.sh
  #!/bin/bash

  /usr/local/rsync/bin/rsync -avzH --progress --exclude=.* --exclude=var --password-file=/usr/local/rsync/rsyncd.secrets /home/wwwroot/wateroa/ [email protected]::wateroa_code

    • 自动同步:每隔五分钟同步一次

        # crontab -e
  */5 * * * * /rsync.sh
