在Ubuntu 7.10下安装好mysql后,root帐户的密码为空,用如下方式登录:

mysql -u root

这里就要设置mysql的安全性了。

设置mysql root用户的密码。

用mysqladmin来设置密码

mysqlmyadmin -u root password 123456

如果有旧密码:

mysqladmin -u root -p password newpass

这时shell会提醒你输入旧密码。更改成功。

另一种方法是进入mysql后更改密码。

set password for 'root'@'localhost'=password('newpass');

或用update 进行更改。

update mysql.user set password=password('newpass') where user='root';

flush privileges;

增加用户

有两种方式

1. grant语句。

grant all privileges on *.* to 'someuser'@'localhost' identified by 'pass' with grant option;

2. 使用update语句,可是有点复杂,,主要是要搞清楚user表的相关内容。

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),
