PHP backup mysql example program_PHP tutorial

We need to use the system’s scheduled task function to back up mysql in php. Next, I will introduce the method of backing up mysql in linux using php.

#Back up all backup files to the specified directory, such as /backup/mysql_data_backup

means to execute the backup command using php at 0:13 every night

The code is as follows

代码如下	复制代码
mkdir /backup/mysql_data_backup -p cd /backup/mysql_data_backup wget /backmysql.txt -O backmysql.php chmod +x backmysql.php crontab -e

Copy code

代码如下	复制代码
0 13 * * * /usr/bin/php /backup/mysql_data_backup/backmysql.php

mkdir /backup/mysql_data_backup -p
cd /backup/mysql_data_backup
wget /backmysql.txt -O backmysql.php
chmod +x backmysql.php
crontab -e

代码如下	复制代码
#!/usr/bin/php < ?php //产生保存目录 $path = dirname(__FILE__) . '/' .date("Ym"); $filename = sprintf("%s/%s.sql.gz", $path, date("YmdHis")); if(!is_dir($path)) mkdir($path); //导出并压缩所有数据库 $cmd = sprintf("/usr/bin/mysqldump -uroot -ppassword --all-databases | /bin/gzip > %s", $filename); echo "backuping...n"; `$cmd`; echo "backup done.n";

Add a line of tasks

Note that this is only the planning information processing. If we want to execute the php file, we need to write one ourselves. http://www.bkjia.com/PHPjc/630679.htmlwww.bkjia.comtrue
