我已经配置了一个集群并且它运行正常，除非我在 php.ini 文件中添加一个 zend 扩展。在我的测试中，我关闭了故障转移服务器，因此我只处理单个服务器。我正在运行 Ubuntu 12.04、corosync 1.4.2 和 drbd 8.4.3 这是我相关的 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 是与 apt-get 一起安装的库存。在这种情况下，它可以正常工作。
但是当我向 /etc/php5/apache2/php.ini 添加一个 zend 负载时：
zend_extension = /var/www/ioncube/ioncube_loader_lin_5.3.so
我可以运行 service apache restart 并启动网站但是如果我尝试从 crm 启动它，它会失败并显示以下日志：

如果我从 /etc/php5/apache2/php.ini 中注释掉 zend 行
;zend_extension = /var/www/ioncube/ioncube_loader_lin_5.3.so
然后启动服务器，它工作。以下是它何时工作的日志：
