关于rsync的介绍网上有很多，这里直接说一下如何使用rsync

本次使用rsync的是将备份文件拉取一份到异地机房，只保留一份

1.首先安装rsync
    yum install rsync
    2.配置rsyncd.conf(如果没有自行创建)
    [root@005---1 ~]# cat /etc/rsyncd.conf
    uid = root
    gid = root
    use chroot = yes
    strict modes = false
    pid file = /var/run/rsyncd.pid
    lock file = /var/run/rsync.lock
    ####
    log file = /var/log/rsyncd.log
    transfer logging = true
    log format= "%o [%a] %m (%u) %f %l %b %c
    reverse lookup = no
    ignore errors = true
    read only = false
    strict modes = yes
    list = false
    max connections = 100
    timeout = 1800
    [backup]
    path = /backup
    auth users = backup
    secrets file = /etc/rsyncd.d/pass.server
    [mysqlbackup]
    path = /mysqlbackup
    auth users = backup
    secrets file = /etc/rsyncd.d/pass.server
    
    3.配置密码文件(如果没有自行创建)
    [root@005---1 ~]# cat /etc/rsyncd.d/pass.server 
    backup:backup
    
    4.授权
    [root@005---1 ~]# chmod 600 /etc/rsyncd.d/pass.server
    
    5.启动
    /usr/bin/rsync --daemon --config=/etc/rsyncd.conf
    
    [root@005---1 ~]# ps -ef|grep rsync
    root       334 30589  0 16:50 pts/7    00:00:00 grep --color=auto rsync
    root      2305     1  0 Jul01 ?        00:00:00 /usr/bin/rsync --daemon --config=/etc/rsyncd.conf
    
    6.定时同步脚本rsync_bakcup.sh
    
    [root@cpe-172-100-1-86 ~]# cat /opt/scripts/rsync_bakcup.sh
    #!/bin/sh
    today=`date --date='0 days ago' +%Y_%m_%d`
    echo $today
    find /data/backup/mongodbbackup/20* -type d -mtime +0|xargs -l rm -rf \;
    find /data/backup/oraclebackup/rman/20* -type d -mtime +0|xargs -l rm -rf \;
    find /data/backup/mysqlbackup/xtrabackup/backup172.200.239.150_3306/20* -type d -mtime +0|xargs -l rm -rf \;
    find /data/backup/mysqlbackup/xtrabackup/backup172.200.239.185_3306/20* -type d -mtime +0|xargs -l rm -rf \;
    find /data/backup/mysqlbackup/xtrabackup/backup172.200.239.186_3306/20* -type d -mtime +0|xargs -l rm -rf \;
    find /data/backup/mysqlbackup/xtrabackup/backup172.200.239.198_3306/20* -type d -mtime +0|xargs -l rm -rf \;
    find /data/backup/mysqlbackup/xtrabackup/backup172.200.250.140_3306/20* -type d -mtime +0|xargs -l rm -rf \;
    
    echo "mongodb ..."
    /usr/bin/rsync -vzrtopg -P backup@172.200.239.187::backup/mongodb_backup/$today  /data/backup/mongodbbackup --bwlimit=300000 --password-file=/etc/rsyncd.d/pass.server
    
    echo "oracle rman backup"
    
    /usr/bin/rsync -vzrtopg -P backup@172.200.239.187::backup/rman/$today  /data/backup/oraclebackup/rman --bwlimit=300000 --password-file=/etc/rsyncd.d/pass.server
    
    today=`date --date='0 days ago' +%Y-%m-%d`
    
    echo $today
    
    echo "backup172.200.239.185_3306"
    
    /usr/bin/rsync -vzrtopg -P backup@172.200.239.187::backup/xtrabackup/backup172.200.239.185_3306/$today  /data/backup/mysqlbackup/xtrabackup/backup172.200.239.185_3306  --bwlimit=300000 --password-file=/etc/rsyncd.d/pass.server
    
    echo "backup172.200.239.186_3306"
    
    /usr/bin/rsync -vzrtopg -P backup@172.200.239.187::backup/xtrabackup/backup172.200.239.186_3306/$today  /data/backup/mysqlbackup/xtrabackup/backup172.200.239.186_3306  --bwlimit=300000 --password-file=/etc/rsyncd.d/pass.server
    
    echo "backup172.200.250.140_3306"
    
    /usr/bin/rsync -vzrtopg -P backup@172.200.239.187::backup/xtrabackup/backup172.200.250.140_3306/$today  /data/backup/mysqlbackup/xtrabackup/backup172.200.250.140_3306  --bwlimit=300000 --password-file=/etc/rsyncd.d/pass.server
    
    echo "backup172.200.239.150_3306"
    
    /usr/bin/rsync -vzrtopg -P backup@172.200.239.187::mysqlbackup/xtrabackup/backup172.200.239.150_3306/$today  /data/backup/mysqlbackup/xtrabackup/backup172.200.239.150_3306  --bwlimit=300000 --password-file=/etc/rsyncd.d/pass.server
    
    echo "backup172.200.239.198_3306"
    
    /usr/bin/rsync -vzrtopg -P backup@172.200.239.187::mysqlbackup/xtrabackup/backup172.200.239.198_3306/$today  /data/backup/mysqlbackup/xtrabackup/backup172.200.239.198_3306  --bwlimit=300000 --password-file=/etc/rsyncd.d/pass.server
