4. modify mahara config.PHP file following settings:
$cfg->dbtype,$cfg->dbname,$cfg->dbuser,$cfg->dbpass
$cfg->dataroot
5. add following settings to config.PHP (这步骤mahara官方网站的安装指南没有，但少了它有可能出错）
$cfg->directorypermissions = 0777; //or 0700?
$cfg->wwwroot = 'http://xxx.xxx.xxx/mahara/';
6. append directory in apache httpd.conf file
for example:
<Directory "/var/www/mahara/web">
AllowOverride All
</Directory>
Alias /mahara "/var/www/mahara/web"

7. restart apache with command "/etc/init.d/httpd restart"
