下载BugFree2：
[root@localhost ~]# wget -chttp://www.bugfree.org.cn/download/bugfree2.tar.gz
解压到Xampp下的htdocs文档下：
[root@localhost ~]#tar xvfz bugfree2.tar.gz -C /opt/lampp/htdocs/
然后复制Include/Config.inc.Sample.php为Include/Config.inc.php，编辑并修改数据库链接地址：编辑/opt/lampp/htdocs/bugfree/Include/Config.inc.php
[root@ua006 lampp]# vi ./htdocs/bugfree/Include/Config.inc.php
*
* @link http://www.bugfree.org.cn/
* @package BugFree
*/
/* Report all errors except E_NOTICE. */
error_reporting(E_ALL ^ E_NOTICE);
/* 1. Define surported language list and default language. Note: you can use only one charset Chinese
lanuage now. */
$_CFG['LangList']['EN_UTF-8'] = 'English UTF-8';
$_CFG['LangList']['ZH_CN_UTF-8'] = 'ZH_CN UTF-8';
$_CFG['DefaultLang'] = 'ZH_CN_UTF-8';
/* 2. Define admin user list. Like this: array('admin','yourloginname') */
$_CFG['AdminUser'] = array('admin');
/* Define report user list. Like this: array('admin', 'someone@example.com');*/
$_CFG['MailReportUser'] = array('');
/* 3. Define the username and password of the BugFree database. */
$_CFG['DB']['User'] = 'root'; // 数据库登录用户名
$_CFG['DB']['Password'] = 'password'; // 数据库登录用户密码
$_CFG['DB']['Host'] = 'localhost'; // 数据库服务器地址
$_CFG['DB']['Database'] = 'bugfree'; // 指定BugFree数据库名称
$_CFG['DB']['TablePrefix'] = 'bf_'; // 数据库表前缀，默认为bf_。除非有冲突，不建议修改或为空
$_CFG['DBCharset'] = 'UTF8'; // 数据库编码设置，保留默认值
注意：这里使用的是已经安装好的mysql管理员账号，账号错误的话页面仍然会提示创建数据库成功，所以一定要注意
，否则问题很难找。
自动发送邮件的配置
/* 8. Mail setting. */
$_CFG['Mail']['On'] = true;
$_CFG['Mail']['FromAddress'] = "124961193@163.com";
$_CFG['Mail']['FromName'] = 'BugFree';
$_CFG['Mail']['ReportTo'] = array(); // Where bug statistics message sened t
o. If empty, to all users.
$_CFG['Mail']['SendMethod'] = 'SMTP'; // MAIL|SENDMAIL|SMTP|QMAIL
/* 9. SMTP param setting. */
$_CFG['Mail']['SendParam']['Host'] = 'smtp.163.com'; // The server to
connect. Default is localhost
$_CFG['Mail']['SendParam']['SMTPAuth'] = true; // Whether or not to use SMTP
authentication. Default is FALSE
$_CFG['Mail']['SendParam']['Username'] = 'etune_song'; // The username to
use for SMTP authentication.
$_CFG['Mail']['SendParam']['Password'] = 'xxx'; // The password to u
se for SMTP authentication.
然后设置文件目录权限：
[root@localhost ~]# cd /opt/lampp/htdocs/bugfree
[root@localhost bugfree]# chmod 777 Data/TplCompile/
[root@localhost bugfree]# chmod 777 BugFile/
[root@localhost bugfree]# chmod 777 Include/Config.inc.php
全部配置好就可以访问BugFree了：
http://localhost/bugfree/设置新的数据库
admin缺省口令123456
按页面提示一步步操作，创建成功后会提示输入admin的口令我用的是bugfreeadmin
登陆后会显示几行警告信息

解决办法：
修改/opt/lampp/etc/php.ini
找到allow_call_time_pass_reference = Off一行，将Off修改为On

数据的备份、恢复
1．备份
做为系统安全保障的一部分，及时、全面的备份是一项必不可少的工作。数据库以及各软件的配置文件、日志等，经常会使管理员晕头转向，一不小心就会漏掉一项。而XAMPP则让这一工作变得非常简单，输入下面的命令就可一步完成：
/opt/lampp/lampp backup ****
命令后面跟着的是MySQL 的 root 用户的密码。命令执行后会看到下面的内容：
Backing up databases...
Backing up configuration, log and htdocs files...
Calculating checksums...
Building final backup file...
Backup finished.
Take care of /opt/lampp/backup/xampp-backup-19-02-06.sh
2．恢复
恢复以前的备份，只需以 root 用户身份运行下面的命令：
# sh /opt/lampp/backup/xampp-backup-19-02-06.sh ****
命令后面跟着的是MySQL 的 root 用户的密码，这时用户将看到如下信息：
Checking integrity of files...
Restoring configuration, log and htdocs files...
Checking versions...
Installed: XAMPP 1.5.1
Backup from: XAMPP 1.5.1
Restoring MySQL databases...
Restoring MySQL user databases...
Backup complete. Have fun!
You may need to restart XAMPP to complete the restore.
恢复完后，需要重新启动XAMPP，才能使恢复的数据可用。
--------------------------------------------------------
如果本机访问没有问题了，但局域网等访问不了的话，可能就是防火墙阻止了，各个linux版本关防火墙有所不同
比如ubuntu的命令就是：#sudo ufw disable
至此，全部安装完成！XAMPP平台真的是个好东西，省去了很多在Linux安装的麻烦！
