Linux中安装rsync同步工具步骤详解

  rsync是一款服务器与服务器这间的同步工具了,通常我们可以利用rsync来实时数据同步操作了,下面我一起来看看安装rsync同步软件的教程.

  安装

  rsync-3.1.0.tar.gz

  #tar zxvf rsync-3.1.0.tar.gz

  #cd rsync-3.1.0

  #./configure --prefix=/home/work/rsync

  #make

  #make install

  rsync服务端的配置;

  环境:192.168.11.11为生产机;192.168.11.12为备份机;

  那么需要192.168.11.11需要作为rsync的client;

  192.168.11.12作为rsync的service端;

  1、192.168.11.12_service端的配置;

  1)[root@cmmailapp2 data]# touch /etc/rsyncd.conf  //此文件为rsync的主配置问题,默认不存在需要手动创建;

  2)定义同步的配置;

  [root@cmmailapp2 data]# cat /etc/rsyncd.conf

  [data]

  path = /data/

  auth users = coremail

  uid = root

  gid = root

  secrets file = /etc/rsyncd.secrets

  read only = no

  [mysql]

  Path = /home/coremail/var/mysql

  auth users = coremail

  uid = root

  gid = root

  secrets file = /etc/rsyncd.secrets

  read only = no

  [cmxt]

  Path = /home/coremail/

  auth users = coremail

  uid = root

  gid = root

  secrets file = /etc/rsyncd.secrets

  read only = no

  3)定义密码文件/etc/rsyncd.secrets

  [root@cmmailapp2 data]# cat  /etc/rsyncd.secrets

  coremail:coremail

  4)启动rsync启动服务

  [root@cmmailapp2 data]# cat /etc/xinetd.d/rsync

  # default: off

  # description: The rsync server is a good addition to an ftp server, as it

  #       allows crc checksumming etc.

  service rsync

  {

  disable = yes           //需要修改为no;

  socket_type     = stream

  wait            = no

  user            = root

  server          = /usr/bin/rsync

  server_args     = --daemon

  log_on_failure  += USERID

  }

  [root@cmmailapp2 data]# chkconfig --level 2345 rsync on

  [root@cmmailapp2 data]# chkconfig rsync on

[Ok3w_NextPage]

  [root@cmmailapp2 data]# chkconfig --level 2345 xinetd on

  [root@cmmailapp2 data]# service xinetd restart

  Stopping xinetd: [  OK  ]

  Starting xinetd: [  OK  ]

  2、192.168.11.11_client端的配置;

  [root@cmmailapp1 /]# cat /etc/rsyncd.secrets

  coremail

  [root@cmmailapp1 /]# rsync -aSvH --password-file=/etc/rsyncd.secrets /home/coremail/coremail@192.168.11.12::data

  [root@cmmailapp1 /]# rsync -aSvH --password-file=/etc/rsyncd.secrets /home/coremail/coremail@192.168.11.12::mysql

  [root@cmmailapp1 /]# rsync -aSvH --password-file=/etc/rsyncd.secrets /home/coremail/coremail@192.168.11.12::cmxt

  五、定义定时自行rsync同步,指定同步的日志所在的路径/var/log/rsync/下;

  [root@cmmailapp1 log]# cat /root/rsync.sh

  DATE=`date +%Y%m%d%H%M`

  rsync -aSvH --password-file=/etc/rsyncd.secrets /home/coremail/ coremail@192.168.11.12::data >/var/log/rsync.date.$DATE

  rsync -aSvH --password-file=/etc/rsyncd.secrets /home/coremail/ coremail@192.168.11.12::mysql >/var/log/rsync.mysql.$DATE

  rsync -aSvH --password-file=/etc/rsyncd.secrets /home/coremail/ coremail@192.168.11.12::cmxt >/var/log/rsync.cmxt.$DATE

  chmod u+x /root/rsync.sh

  [root@cmmailapp1 log]# crontab -l

  0 3 * * * /root/rsync.sh

  执行时候的日子记录文件:

  [root@cmmailapp1 log]# ls |grep 'rsync'

  rsync.cmxt.201110180915

  rsync.date.201110180915

  rsync.mysql.201110180915

  启动

  rsync --daemon --port 3334 --config=/home/work/rsync/conf/rsyncd.conf

  错误1

  @ERROR: setgroups failed

  rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]

  这个错我是由于 起服务的 rsync 和 传输的rsync的版本不用。后来换成一个版本后就好了。

  ps大家要注意一点的时rsync软件是分服务器端与客户端两种,也就是主从服务器了,所以安装版本是不一样的哦.
