验证管理节点config.ini参数配置的shell脚本,看memory是否超标,运行的时候需要附带上面data node id,而且cluster要处于工作状态,最起码manage node和data node要处于启动状态

run check_memery.sh

脚本内容下:

# 注明,,是从网友飞鸿大哥那里趴过来,改改运行通过的,肯定有很多需要完善的地方,欢迎大家提出宝贵的意见。

#!/bin/bash

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),
