【问题标题】：Ubuntu 14.04 Server: Apache2 issue with phpMyAdminUbuntu 14.04 服务器：phpMyAdmin 的 Apache2 问题
【发布时间】：2016-11-21 03:51:44
【问题描述】：

我已经安装了 Apache 2，它运行良好。我已经安装了 PHP 7，一切正常，但是当我安装 phpMyAdmin 时，Apache 2 停止工作。在检查 Apache 2 时，它甚至不加载默认页面。

当我重新启动 Apache 2 时，出现以下错误：

root@ip-172-31-30-202:~# service apache2 restart
* Restarting web server apache2                                                                                                                                   [fail]
* The apache2 configtest failed.
Output of config test was:
Segmentation fault (core dumped)
Action 'configtest' failed.
The Apache error log may have more information.

我正在使用Ubuntu 14.04 (Trusty Tahr)。

【问题讨论】：

您应该检查错误日志。转到 /var/log/apache2/error.log

标签： php apache ubuntu server apache2

【解决方案1】：

这对我有用：

cd /etc/apache2/mods-enabled
rm php5.conf 
rm php5.load 

sudo service apache2 start;

成功了:))))))

另请参阅apache2 segfault after update。

【讨论】：

我不知道如何或为什么，但你的解决方案也对我有用。
我尝试在已经安装 PHP 7.1 的情况下安装 phpmyadmin，然后它尝试用 php5 做一些奇怪的事情 :( 这个解决方案对我有用。
为我工作，你拯救了我的一天 :) :)
像魅力一样工作。感谢您让我不必再重新配置整个服务器的麻烦：D
我也不知道为什么，但这个解决方案也对我有用，哇，你的救命稻草！

【解决方案2】：

Apache 默认不转储内核。看看http://www.omh.cc/blog/2008/mar/6/fixing-apache-segmentation-faults-caused-php/。

【讨论】：

【解决方案3】：

在终端中运行这些命令：

vim /etc/apache2/apache2.conf

将以下内容添加到文件底部：

# phpMyAdmin Configuration
Include /etc/phpmyadmin/apache.conf

然后重启Apache：

sudo service apache2 restart

【讨论】：

【解决方案4】：

通过卸载 Apache 2 解决了这个问题：

sudo apt-get purge apache2

我安装了phpMyAdmin：

sudo apt-get -y install phpmyadmin

然后我安装了apache2：

sudo apt-get install apache2
