前言:

如果你的MySQL数据库文件较大,可能备份的时候需要占用很多服务器资源,所以站长要尽量选择访客最少的时间段执行自动备份命令,比如凌晨4-5点左右。而且要注意给备份留下足够的时间然后执行存储命令。

第一步:

首先要支持crontab,如果不支持的话,请参考我的博客:Linux VPS/服务器上用Crontab来实现VPS自动化

第二步:

shell脚本->mysqlbak.sh

#!/bin/bash

BACKPATH='存储文件路径'
D=`date +%Y-%m-%d_%H%M%S`
NAME=$D.sql.gz

/usr/local/mysql/bin/mysqldump -u数据库名 -p数据库密码 指定的数据库 --skip-lock-tables | gzip > $BACKPATH/$NAME

第三步:

定时任务执行 每天两点后执行。具体可以根据个人情况哦!

执行命令:crontab -e

00 02 * * * /脚本路径/mysqlbak.sh

因为一个服务器可能会遭到天灾人祸,,备份的数据库文件要存在不同的服务器或者下载到本地更保险。其实就是这么简单啦!

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
