定時備份docker部署的mysql數據

1.新建腳本,添加腳本內容

vi   mysql_backup_test_backup.sh 

#!/bin/bash
# 設置mysql的登錄用戶名和密碼(根據實際情況填寫)
mysql_user="root"
mysql_password="root"
mysql_host="localhost"
mysql_port="3306"
mysql_charset="utf8mb4"
 
# 備份文件存放地址(根據實際情況填寫)
backup_location=/usr/local
 
# 是否刪除過期數據
expire_backup_delete="ON"
expire_days=7
backup_time=`date +%Y%m%d%H%M`
backup_dir=$backup_location
welcome_msg="Welcome to use MySQL backup tools!"


# 備份指定數據庫中數據(此處假設數據庫是mysql_backup_test)

　docker exec -it mysql mysqldump -h$mysql_host -P$mysql_port -u$mysql_user -p$mysql_password -B test1 > $backup_dir/mysql_backup_test-$backup_time.sql

 
# 刪除過期數據
if [ "$expire_backup_delete" == "ON" -a  "$backup_location" != "" ];then
        `find $backup_location/ -type f -mtime +$expire_days | xargs rm -rf`
        echo "Expired backup data delete complete!"
fi

2.新建定時任務

#新建定時任務命令
crontab -e
#查看定時任務命令
crontab -l
#刪除所有定時任務命令
crontab -r
