HomeDatabaseMysql TutorialCentOS 6.4下实现Oracle的定时备份

在CentOS 6.4环境下,实现每天晚上23:00备份用户数据库方案:利用linux下的定时任务机制,命令为crontab;导出数据库用到exp工具

目标:在CentOS 6.4环境下,实现每天晚上23:00备份用户数据库方案:利用linux下的定时任务机制,命令为crontab;导出数据库用到exp工具;然后让crontab定时去调用exp来  实现自动备份的目的。

步骤:

1,用oralce用户登录--》

编写备份Oracle数据库的sh文件--oracle_backup.sh;

内容为:su - oracle c "$bin/exp $username/$password file=$date_backup.dmp owner=$user  log=$date_log"

动态拼接日期的sh: rq = `date +"%Y%m%d"`

为上面的命令建立文件夹

mkdir backup_data;  存放备份文件

mkdir back_log;  存放log

完后,记得给该文件赋予可写的权限: chmod 777 $path/oracle_backup.sh

2,  用root用户登录执行命令--》

#  crontab -e

内容为:

0 23 * * * "$path/oracle_back.sh"        (分 时 天 月 星期)

此命令会在 /var/spool/cron 下生成一个root文件,内容为上面一行的输入。

3,检查是否成功

crontab -l 可以查看当前用户下的周期任务

crontab -r 移除当前用户下的周期任务

MySQL: A Beginner-Friendly Approach to Data StorageMySQL: A Beginner-Friendly Approach to Data StorageApr 17, 2025 am 12:21 AM

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL: Database Management System vs. Programming LanguageMySQL: Database Management System vs. Programming LanguageApr 16, 2025 am 12:19 AM

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL: Managing Data with SQL CommandsMySQL: Managing Data with SQL CommandsApr 16, 2025 am 12:19 AM

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.
