5

我正在使用 Amazon Linux AMI，我卸载 PHP 5.6 和一些扩展，然后安装 PHP 7.0 和一些扩展。这一切都可以正常工作几个星期，然后突然 PHP 5.6 和我之前拥有的扩展再次安装，而我没有做任何事情（据我所知）导致这种情况。这似乎在我的一些服务器上随机发生，但在其他服务器上却没有。

这是我的 YUM 日志：

因此 PHP 5.6 在 4 月 3 日被删除，然后在 4 月 26 日再次安装。然而，该网站仅在 4 月 30 日“切换”回 PHP 5.6。

在另一台服务器上，我有这个日志，它显示一些更新也被自动启动：

Amazon Linux 上的 YUM 是否默认开启了自动更新？如果是这样，为什么它会重新安装我卸载的软件包，我该如何防止呢？

根据我们的评论，我看到仍然安装了 PHP7，但是安装了 PHP5.6 以及其他东西的依赖项。

如果您使用 PHP 7 作为 apache 模块，您需要做的第一件事就是替换它。

在 /etc/httpd 或 /etc/apache2 中的某处，应该有一个看起来像这样的文件：

#LoadModule php5_module                 modules/libphp5.so
LoadModule php7_module                  modules/libphp7.so

注释掉 php5，添加/取消注释 php7。检查正确的路径。

然后使用以下命令重新启动 Apache 网络服务器：

service httpd restart

或者

service apache2 restart

然后，出于好奇，尝试卸载 PHP 5.6，您可能会看到依赖项。

因为您可能需要保留 PHP 5.6，请在此处查看如何冻结软件包升级
https://access.redhat.com/solutions/10185

编辑/etc/yum.conf并添加

exclude=php*

然后你可以做 yum update 来检查会发生什么。

如果这是不能停止的实时服务器，请格外小心，因为某些步骤中的错误可能会导致网络服务器停机。
