PostgreSQL开源监控工具——pgwatch详细安装和测试

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 http://www.cybertec.at/download/pgwatch/pgwatch-1.0.tar.gz

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 http://www.php.net/manual/en/book.pgsql.php)      # 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 "<table>\n";

while ($line = pg_fetch_array($result, null, PGSQL_ASSOC)) {

    echo "\t<tr>\n";

    foreach ($line as $col_value) {

        echo "\t\t<td>$col_value</td>\n";

    }

    echo "\t</tr>\n";

}

echo "</table>\n";

 

// Free resultset

pg_free_result($result);

 

// Closing connection

pg_close($dbconn);

?>
