安装好bugzilla和testlink后，打开testlink安装目录下，找到config.inc.php
　　查找如下字段，修改为bugzilla 红色字体部分。
/**
* @var STRING TL_INTERFACE_BUGS = ['NO', 'BUGZILLA','MANTIS','JIRA']
* BUGZILLA: edit configuration in TL_ABS_PATH/cfg/bugzilla.cfg.php
* MANTIS  : edit configuration in TL_ABS_PATH/cfg/mantis.cfg.php
* JIRA    : edit configuration in TL_ABS_PATH/cfg/jira.cfg.php
*/
define('TL_INTERFACE_BUGS','BUGZILLA');
require_once(TL_ABS_PATH . 'lib/bugtracking/int_bugtracking.php');

　　另外修改testlink下的cfg目录内文件bugzilla.cfg.php

　　配置mysql连接相关信息及bugzilla发布地址
<?php

*/
//Set the bug tracking system Interface
/** The DB host to use when connecting to the Bugzilla db */
define('BUG_TRACK_DB_HOST', 'localhost');
/** The name of the database that contains the Bugzilla tables */
define('BUG_TRACK_DB_NAME', 'bugs');
/** The DB type being used by Bugzilla */
define('BUG_TRACK_DB_USER', 'bugs');
/** The DB password to use for connecting to the Bugzilla db */
define('BUG_TRACK_DB_PASS', 'xxxxxx');
/** link of the web server */
define('BUG_TRACK_HREF', "http://xxx.xxx.xxx.xxx/test/show_bug.cgi?id=");
/** link to the bugtracking system, for entering new bugs */
define('BUG_TRACK_ENTER_BUG_HREF',http://xxx.xxx.xxx.xxx/);
