mysql实现自动远程备份1办法
mysql实现自动远程备份一办法 ? 一、实现本地自动备份数据库很简单: 1.以root身份登陆 2.计划任务(每天的3:30自动执行 /usr/bin/mysqlbackup) crontab 0 3:30 * * * /usr/bin/mysqlbackup 3.写一个自动备份数据库脚本 vi /usr/bin/mysqlbackup #!/bin/bas
mysql实现自动远程备份一办法?
一、实现本地自动备份数据库很简单:1.以root身份登陆
2.计划任务(每天的3:30自动执行 /usr/bin/mysqlbackup)
crontab
0 3:30 * * * /usr/bin/mysqlbackup
3.写一个自动备份数据库脚本
vi /usr/bin/mysqlbackup
#!/bin/bash
mv /home/.../db_bak5.tgz /home/.../db_bak6.tgz
mv /home/.../db_bak4.tgz /home/.../db_bak5.tgz
mv /home/.../db_bak3.tgz /home/.../db_bak4.tgz
mv /home/.../db_bak2.tgz /home/.../db_bak3.tgz
mv /home/.../db_bak1.tgz /home/.../db_bak2.tgz
rm -rf /home/.../db_bak.txt
/usr/bin/mysqldump -uroot -ppassword dbname
> /home/.../db_bak.txt
cd /home/.../
tar czvf db_bak1.tgz db_bak.txt
二、这样每天的3:30就会在本地目录/home/.../下生成相应的数据库备份,开始由于/home/.../目录下缺少数据系统会提示错误,这是正常的
三、至于远程备份可以配合使用ftp或scp命令实现,方法很简单,查一下相关命令的使用,然后再改动一下mysqlbackup脚本就可以了
在win2003下MySQL数据库每天自动备份
终于让服务器每天早上备份一次 MySQL 数据库并自动打包,同时删除 5 天前的备份文件. 分享如下.
1. 环境: windows server 2003 + Apache 2.0 + PHP5 + MySQL 4.0.26 .
2. 假设 PHP 安装目录为 D:/php ,MySQL 安装目录为 D:/mysql.
3. 在 D:/php 下建立目录 WinRAR, 把你 winrar 安装目录下的 WinRAR.exe 和 RARReg.KEY 复制到 D:/php/WinRAR .
4. D:/php 下建立文件 mysql_backup.php:
/*/////////////////////////
#FileName: mysql_backup.php
#Author: faisun
#Website: http://www.softpure.com
////////////////////////*/
//保存目录,路径要用反斜杠.您需要手动建立它.
$store_folder = 'D:\databse_backup';
//用户名和密码
//该帐号须有操作[所有]的数据库及FILE的权限
//否则有些数据库不能备份.
$db_username = "root";
$db_password = "";
$time=time();
$nowdir = "$store_folder\\".date("Ymd",$time)."";
if(file_exists("$nowdir.rar")) die("File exists.\n");
@mkdir($nowdir);
mysql_connect("localhost","$db_username","$db_password");
$query=mysql_list_dbs();
while($result=mysql_fetch_array($query)){
system (dirname(__FILE__).'\..\mysql\bin\mysqldump --opt '."$result[Database]
-u{$db_username} ".($db_password?"-p{$db_password}":"")." >
$nowdir\\$result[Database].sql");
echo "dumping database `$result[Database]`...\n";
}
echo "\nWinrar loading...\n";
system( dirname(__FILE__)."\\WinRAR\\WinRAR.exe a -ep1 -r -o+ -m5 -df \"$nowdir.rar\"
"$nowdir\" " );
//删除 5 天前的文件
@unlink("$store_folder\\".date("Ymd",$time-86400*5).".rar");
echo "\nOK!\n";
>
5. D:/php 下建立文件 mysql_backup.bat,内容只有一句:
php.exe mysql_backup.php
6. 双击该 bat 文件运行,如果能备份了,OK,下一步添加任务计划.
7. 把 D:/php/mysql_backup 添加到任务计划,时间选每天. 根据服务器的监测结果,每天早上 5-8 时为流量低峰期. 由于 5-7 时有些数据库的清理工作,可以把时间定在了早上 8 点整.
mysql的自动备份------这篇来自动网
time=`date +%G%I%d%H%M` #年月日时分
db=products
echo "#产品库\r\n" >/sqlbak/${db}_$time.sql #备份文件名为[库名_年月日时分.sql]
mysqldump --add-drop-table -c --allow-keywords --force --password=1234567890 --user=root $db >>/sqlbak/${db}_$time.sql
db=news #另一个库
echo "#新闻库\r\n" >/sqlbak/${db}_$time.sql
mysqldump --add-drop-table -c --allow-keywords --force --password=1234567890 --user=root $db |bzip2 -9 >/sqlbak/${db}_$time.sql.bz2
#--add-drop-table是添加一个删出命令。
#-c是完整插入,每行插入都包括字段名
#--force是出错也继续
#--allow-keywords是对于保留字做字段名时对字段名加反引号。

Big data structure processing skills: Chunking: Break down the data set and process it in chunks to reduce memory consumption. Generator: Generate data items one by one without loading the entire data set, suitable for unlimited data sets. Streaming: Read files or query results line by line, suitable for large files or remote data. External storage: For very large data sets, store the data in a database or NoSQL.

Backing up and restoring a MySQL database in PHP can be achieved by following these steps: Back up the database: Use the mysqldump command to dump the database into a SQL file. Restore database: Use the mysql command to restore the database from SQL files.

MySQL query performance can be optimized by building indexes that reduce lookup time from linear complexity to logarithmic complexity. Use PreparedStatements to prevent SQL injection and improve query performance. Limit query results and reduce the amount of data processed by the server. Optimize join queries, including using appropriate join types, creating indexes, and considering using subqueries. Analyze queries to identify bottlenecks; use caching to reduce database load; optimize PHP code to minimize overhead.

How to insert data into MySQL table? Connect to the database: Use mysqli to establish a connection to the database. Prepare the SQL query: Write an INSERT statement to specify the columns and values to be inserted. Execute query: Use the query() method to execute the insertion query. If successful, a confirmation message will be output.

Creating a MySQL table using PHP requires the following steps: Connect to the database. Create the database if it does not exist. Select a database. Create table. Execute the query. Close the connection.

To use MySQL stored procedures in PHP: Use PDO or the MySQLi extension to connect to a MySQL database. Prepare the statement to call the stored procedure. Execute the stored procedure. Process the result set (if the stored procedure returns results). Close the database connection.

One of the major changes introduced in MySQL 8.4 (the latest LTS release as of 2024) is that the "MySQL Native Password" plugin is no longer enabled by default. Further, MySQL 9.0 removes this plugin completely. This change affects PHP and other app

Oracle database and MySQL are both databases based on the relational model, but Oracle is superior in terms of compatibility, scalability, data types and security; while MySQL focuses on speed and flexibility and is more suitable for small to medium-sized data sets. . ① Oracle provides a wide range of data types, ② provides advanced security features, ③ is suitable for enterprise-level applications; ① MySQL supports NoSQL data types, ② has fewer security measures, and ③ is suitable for small to medium-sized applications.
