rsync 安装配置

主服务器上配置

ubuntu 默认安装了rsync，但是并没有作为服务启动

基本配置

• 在/etc下创建一个rsync目录

    $ mkdir -m 600 rsync
  

• 拷贝配置文件样本

    $ cd rsync/
      
    $ cp /usr/share/doc/rsync/examples/rsyncd.conf ./
  

• 配置rsyncd.conf

    $:/etc/rsync# vim rsyncd.conf
  

  修改信息

      # sample rsyncd.conf configuration file
        
      # GLOBAL OPTIONS
        
      motd file=/etc/rsync/rsyncd.motd
      log file=/var/log/rsyncd
      # for pid file, do not use /var/run/rsync.pid if
      # you are going to run rsync out of the init.d script.
      # The init.d script does its own pid file handling,
      # so omit the "pid file" line completely in that case.
      pid file=/var/run/rsyncd.pid
      syslog facility=daemon
      #socket options=
        
      # MODULE OPTIONS
        
      [app]
        
          comment = app
          path = /data0/web/app
          use chroot = yes
      #   max connections=10
          lock file = /var/lock/rsyncd
      # the default for read only is yes...
          read only = yes
          list = yes
          uid = nobody
          gid = nogroup
          exclude = uploadfiles/
      #   exclude from = 
      #   include =
      #   include from =
      #   auth users = 
          secrets file = /etc/rsygn/rsyncd.secrets
          strict modes = yes
      #   hosts allow =
      #   hosts deny =
          ignore errors = no
          ignore nonreadable = yes
          transfer logging = no
      #   log format = %t: host %h (%a) %o %f (%l bytes). Total %b bytes.
          timeout = 600
          refuse options = checksum dry-run
          dont compress = *.gz *.tgz *.zip *.z *.rpm *.deb *.iso *.bz2 *.tbz
  

• 配置 rsyncd.secrets

    $:/etc/rsync# vim rsyncd.secrets
  

  加入用户和密码 backup:xxxxx

• 配置 rsyncd.motd

    $:/etc/rsync# vim rsyncd.motd
  

  加入 Welcome Man!

配置rsync 服务

$:/etc/rsync# vim /etc/default/rsync 

修改文件, RSYNC_ENABLE 设置为true， 并指定配置文件为/etc/rsync/rsyncd.conf

  # defaults file for rsync daemon mode
  
  # start rsync in daemon mode from init.d script?
  #  only allowed values are "true", "false", and "inetd"
  #  Use "inetd" if you want to start the rsyncd from inetd,
  #  all this does is prevent the init.d script from printing a message
  #  about not starting rsyncd (you still need to modify inetd's config yourself).
  RSYNC_ENABLE=true
  
  # which file should be used as the configuration file for rsync.
  # This file is used instead of the default /etc/rsyncd.conf
  # Warning: This option has no effect if the daemon is accessed
  #          using a remote shell. When using a different file for
  #          rsync you might want to symlink /etc/rsyncd.conf to
  #          that file.
  RSYNC_CONFIG_FILE=/etc/rsync/rsyncd.conf
  
  # what extra options to give rsync --daemon?
  #  that excludes the --daemon; that's always done in the init.d script
  #  Possibilities are:
  #   --address=123.45.67.89      (bind to a specific IP address)
  #   --port=8730             (bind to specified port; default 873)
  RSYNC_OPTS=''
  
  # run rsyncd at a nice level?
  #  the rsync daemon can impact performance due to much I/O and CPU usage,
  #  so you may want to run it at a nicer priority than the default priority.
  #  Allowed values are 0 - 19 inclusive; 10 is a reasonable value.
  RSYNC_NICE=''
  
  # run rsyncd with ionice?
  #  "ionice" does for IO load what "nice" does for CPU load.
  #  As rsync is often used for backups which aren't all that time-critical,
  #  reducing the rsync IO priority will benefit the rest of the system.
  #  See the manpage for ionice for allowed options.
  #  -c3 is recommended, this will run rsync IO at "idle" priority. Uncomment
  #  the next line to activate this.
  # RSYNC_IONICE='-c3'
  
  # Don't forget to create an appropriate config file,
  # else the daemon will not start.

启动服务

$:/etc/rsync# sudo service rsync start
* Starting rsync daemon rsync

在客户端同步

rsync -vzrtopg --progress --delete backup@120.24.**.**::app ./

自动同步定时脚本

• shell脚本 vim /data0/shell/rsync.sh

    #!/bin/bash
    rsync -zrtopg --progress --delete --password-file=/etc/rsync/rsync.secrets backup@120.24.78.68::app /data0/web/app/
  

• 定时脚本 vim /data0/shell/rsync_cron

    # rsycn crontab shell
    */5 * * * * root sh /data0/shell/rsync.sh >> /data0/log/rsync.log
  

• 加入crontab

    $ crontab /data0/shell/rsync_cron
  

• 自动加载任务，加到入/etc/cron.d/

    ln -s /data0/shell/rsync_cron /erc/cron.d/rsync_cron
  

其他

• 开启cron.log, vim /etc/rsyslog.d/50-default.conf，重启rsyslog
• cron每一个任务都是一整行，为防止任务载入失败，所以在每个任务后面都需要打一个换行
