PostgreSQL开源监控工具pgwatch详细安装和测试
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);
?>
