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.

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

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";
