zabbix显示空白:PHP Fatal error: Call to undefined function bcscale()

启动zabbix_server 然后打开httpd

但是浏览器打开zabbix页面显示空白。

apache错误日志如下： 

[Thu Apr 07 16:59:53 2011] [error] [client 202.102.134.56] PHP Fatal error:  Call to undefined function bcscale() in /var/www/html/include/defines.inc.php on line 796

========================

系统没有安装bcmath

yum install php-bcmath即可。
