首先本人是在linux下完成的如上配置,windows下没有试过,在作者的文档中说,在linux下可以用setup.sh进行安装操作,本人尝试许久
pgwatch详细安装和测试
安装时一直出错,,但是网上又搜不到任何文档决定自己写一篇详细的安装文档。
1.下载pgwatch,我这里我用的版本是1.0,下载地址如下:
wget
2.解压并打开README文件,查看安装所需,这里的安装就不详细讲解
tar -zxvf pgwatch-1.0.tar.gz
vim README
------------------------------------------------------------
Requirements:
-------------
You will need a handful of components to make this work:
- Apache (webserver) # apache用作web服务器
- PHP 5 (scripting language) # php5版本
- pgsql extension for PHP (see ) # postgresql的php客户端
- PostgreSQL 9 (to store the data we collect) # postgresql支持最低版本为9
- dblink (contribution module for PostgreSQL 9) # 需要安装dblink(并非默认安装)
- For now we only support PostgreSQL >= 9.0 databases.
Older systems cannot be monitored, however, we will
add support for future database releases.
3.首先把你刚刚解压的文件夹,放在apache的目录下。(这里要注意的是要设置好文件夹的权限)
4.检测是否安装postgresql的php客户端,如果没有可以直接用yum安装:
yum installphp-pgsql.i386(我的是32位,同学们可以自己用yum search搜索下,之后重启apache)
检测是否安装脚本(php):
// Connecting, selecting database
$dbconn = pg_connect("host=192.168.30.200 port=5434 dbname=lengzijian user=postgres password=123456")
or die('Could not connect: ' . pg_last_error());
// Performing SQL query
$query = 'SELECT * FROM t_user limit 10';
$result = pg_query($query) or die('Query failed: ' . pg_last_error());
// Printing results in HTML
echo "
$col_value | \n";
// Free resultset
pg_free_result($result);
// Closing connection
pg_close($dbconn);
?>

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 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),
