监控工具：Gearman-Monitor¶
Gearman-Monitor是使用PHP实现的Gearman Servers的监控工具。Github仓库在此。
-
首先准备好PHP环境和一个Apache服务器。我把它装在本机上，环境是64位的Win7。采用的PHP环境是PHP 5.5.29，Web Server是Apache 2.4.12。
-
将下载的Gearman-Monitor解压至apache的
htdocs，启动apache，打开http://127.0.0.1/Gearman-Monitor/index.php，出现如下提示。
Net_Gearman package not found!
You can get it at http://pear.php.net/package/Net_Gearman/ or install by pear:
pear install Net_Gearman
原因是Gearman-Monitor需要基于pear的Net_Gearman包。Net_Gearman的下载地址在此。Net_Gearman的使用方法有两种，一是直接将Net_Gearman包下的Net文件夹copy到PHP的根目录下（另一说是PHP的lib目录下的PHP文件夹下），这种方法没有试验过。二是安装pear，执行pear install Net_Gearman-0.2.3即可。下面采用第二种方式安装。
- 安装pear
为防止安装时出现权限问题，以管理员身份打开CMD。先下载http://pear.php.net/go-pear.phar文件到PHP根目录下，然后执行：
出现提示：
直接Enter，采用默认system。

直接Enter，接着会出现一些警告，例如：
Beginning install...
PHP Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timez
one setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting
this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please se
t date.timezone to select your timezone. in phar://D:/twen/php-5.5.29/go-pear.phar/PEAR/Registry.php on line 1012
因为安装PHP环境是我没有设置时区，这里先忽略。

WARNING! The include_path defined in the currently used php.ini does not
contain the PEAR PHP directory you just specified:
<D:\twen\php-5.5.29\pear>
If the specified directory is also not in the include_path used by
your scripts, you will have problems getting any PEAR packages working.
Would you like to alter php.ini <D:\twen\php-5.5.29\php.ini>? [Y/n] : Y
选择Y，这里增加pear配置到php.ini。

bat command
The 'pear' command is now at your service at d:\twen\php-5.5.29\pear.bat
** The 'pear' command is not currently in your PATH, so you need to
** use 'd:\twen\php-5.5.29\pear.bat' until you have added
** 'D:\twen\php-5.5.29' to your PATH environment variable.
Run it without parameters to see the available actions, try 'pear list'
to see what packages are installed, or 'pear help' for help.

$i = 0;
$cfgServers = array();
$cfgServers[$i]['address'] = '192.168.56.101:4730';
$cfgServers[$i]['name'] = '192.168.56.101';
++ $i;
/** 多个Server配置 **/
// $cfgServers[$i]['address'] = '192.168.56.102:4730';
