Ubuntu 12.04起搏器集群在php.ini中添加ioncube zend加载程序后无法加载Apache

我已经配置了一个集群，除非在php.ini文件中添加zend扩展名，否则它可以正常运行。在我的测试中，我关闭了故障转移服务器，所以我只处理一台服务器。我运行的是Ubuntu 12.04、corosync 1.4.2和drbd 8.4.3以下是我的相关crm配置：

primitive apache2 ocf:heartbeat:apache '
        params configfile="/etc/apache2/apache2.conf" httpd="/usr/sbin/apache2" '
        operations $id="apache2-operations" '
        op monitor interval="15s" '
        op start interval="0" timeout="240s" '
        op stop interval="0" timeout="240s" '
        meta target-role="started"

我的php.ini是使用apt-get安装的常用php.ini在这种情况下，它运行良好。

但是，当我将zend加载添加到/etc/php5/apache2/php.ini时：

zend_extension = /var/www/ioncube/ioncube_loader_lin_5.3.so

我可以运行服务apache重启和网站但如果我尝试从crm启动它，它会失败，并显示以下日志：

如果我注释掉/etc/php5/apache2/php.ini 中的zend行

;zend_extension = /var/www/ioncube/ioncube_loader_lin_5.3.so

然后启动服务器，它就工作了。以下是它工作时的日志：
