rsync 拉取备份文件(支持断点续传)

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 [email protected]::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 [email protected]::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 [email protected]::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
