搭建rsync服务并同步重要数据

在主备机器上均安装rsync，在主机上以daemon的模式启动，在备机上定时执行同步命令。安装rsync的命令如下：

1、下载安装包（主备机均执行）

[root@localhost home]# wget http://rsync.samba.org/ftp/rsync/src/rsync-3.0.4.tar.gz
---- ::--  http://rsync.samba.org/ftp/rsync/src/rsync-3.0.4.tar.gz

-- :: ( KB/s) - ‘rsync-3.0..tar.gz’ saved [/]

2、编译安装（主备机均执行）

[root@localhost home]# tar -xvzf rsync-3.0..tar.gz
[root@localhost home]# cd rsync-3.0.
[root@localhost rsync-3.0.]# ./configure --prefix=/usr/local/rsync
[root@localhost rsync-3.0.]# make && make install

3、配置（主机执行）

[root@localhost rsync-3.0.]# mkdir /usr/local/rsync/logs
[root@localhost rsync-3.0.]# mkdir /usr/local/rsync/etc
[root@localhost rsync-3.0.]# mkdir /usr/local/rsync/run
[root@localhost rsync-3.0.]# vim  /usr/local/rsync/etc/rsyncd.conf
[root@localhost rsync-3.0.]# cat  /usr/local/rsync/etc/rsyncd.conf

uid = root
gid = root
port =
use chroot = no
hosts allow = 10.0.251.159   #允许连接的主机IP，在我们的环境中，该IP为备机IP
#hosts deny =  192.168.10.0/
pid file = /usr/local/rsync/run/rsyncd.pid
lock file = /usr/local/rsync/run/rsync.lock
log file = /usr/local/rsync/logs/rsyncd.log
ignore errors
 
#配置待同步的目录，以及同步时所需的认证信息
[mysql_dump]
path = /home/data/mysqldumpdata/
auth users = root
secrets file = /usr/local/rsync/rsyncd.pass
read only = no

[fdfs_data]
path = /home/log_data/fdfs
auth users = root
secrets file = /usr/local/rsync/rsyncd.pass
read only = no

[root@localhost rsync-3.0.]# vim /usr/local/rsync/rsyncd.pass
root:密码

[root@localhost rsync-3.0.]# chmod  /usr/local/rsync/rsyncd.pass

主机上以daemon的形式启动rsync server，命令如下（主机执行）：

[root@localhost rsync-3.0.]# /usr/bin/rsync --daemon --config=/usr/local/rsync/etc/rsyncd.conf &
[] 

在备机上手动执行同步命令，测试是否能够将主机的数据同步到备机之上（备机执行）：

[root@host---- ltp_bak_data]# /usr/bin/rsync -avz --delete --password-file=/usr/local/rsync/rsyncd.pass  root@192.168.32.3::mysql_dump /home/ltp_bak_data/mysql_dump/

[root@host---- ltp_bak_data]# /usr/bin/rsync -avz --delete --password-file=/usr/local/rsync/rsyncd.pass  root@192.168.32.3::fdfs_data /home/ltp_bak_data/fdfs_data/

在备机上，将同步命令加到cron表达式中，设置为每十分钟执行一次（备机执行）

[root@host---- ltp_bak_data]# crontab -l
*/ * * * * /usr/bin/rsync -avz --delete --password-file=/usr/local/rsync/rsyncd.pass  root@192.168.32.3::mysql_dump /home/ltp_bak_data/mysql_dump/
*/ * * * * /usr/bin/rsync -avz --delete --password-file=/usr/local/rsync/rsyncd.pass  root@192.168.32.3::fdfs_data /home/ltp_bak_data/fdfs_data/

附，数据库每日备份，并清理七天前数据脚本

[root@localhost ~]# vi /home/data/mysqldumpdata/dump.sh
#!/bin/bash

#dump sql data from database
hostIP=$
/usr/bin/mkdir -p /home/data/mysqldumpdata
dataStr=`/usr/bin/date +%Y-%m-%d`
destFile="/home/data/mysqldumpdata/scriptstranslation-"${dataStr}".sql"
/usr/bin/mysqldump -u root -p123456 -h $hostIP scriptsTranslation > $destFile

#clear seven days age dump data
sevenDayAgoStr=`date -d '7 day ago' +%Y-%m-%d`
destRmFile="/home/data/mysqldumpdata/scriptstranslation-"${sevenDayAgoStr}".sql"
/usr/bin/rm -rf $destRmFile

[root@localhost ~]# crontab -l
  * * * /home/data/mysqldumpdata/dump.sh 192.168.*.*     #此处要配置服务器IP
