物理机备份

控制节点备份：

备份openstack的mysql数据库并拷贝到192.168.8.66:/opt/backup/openstack_mysql/目录：

vim /backup/shell/backupmysql.sh

#!/bin/bash

backup_dir="/backup/mysql"

filename="${backup_dir}/mysql-`hostname`-`eval date +%Y%m%d`.sql.gz"

# Dump the entire MySQL database

/usr/bin/mysqldump --opt --all-databases | gzip > $filename

scp $filename 192.168.8.66:/opt/backup/openstack_mysql/

# Delete backups older than 7 days

find $backup_dir -ctime +7 -type f -delete

加入定时程序：

crontab -e

0 0 * * * /backup/shell/backupmysql.sh &>/dev/null

（注意，scp需要建立信任关系，在目的主机的authorized_keys中加入源主机的id_rsa_pub验证码）

备份openstack的/etc目录：

vim /backup/shell/backup_etc.sh

#!/bin/bash

backup_dir="/backup/etc"

filename="${backup_dir}/etc-`hostname`-`eval date +%Y%m%d`.gz"

# Dump the entire MySQL database

tar czf $filename /etc

scp $filename 192.168.8.66:/opt/backup/openstack_files/

# Delete backups older than 7 days

find $backup_dir -ctime +7 -type f -delete
