Apache2网络服务器正在运行，但在迁移到ubuntu18.04之后不提供服务

Question

我感谢你的一点帮助，我花了几天的时间试图纠正这个问题。

基本上，我的web服务器只有在php7.2失活之后才能正常运行。

首先，我尝试去激活所有的PHP版本

sudo a2dismod php7.2
sudo a2dismod php5
sudo a2dismod php7.0
sudo systemctl restart apache2

没有错误，web服务器工作和服务Wordpress。现在让我们启用php7.2

sudo a2enmod php7.2
sudo systemctl restart apache2
sudo a2query -m php7.2
>php7.2 (enabled by site administrator)

现在web服务器不工作了。不能为wordpress服务。没有显示错误

 sudo systemctl status apache2

解决了问题: sudo /etc/php/ 7.2 /cli/php.ini不推荐gd2扩展: extension=gd2删除、清除和安装php7.2-gd加载模块: phpenmod -v 7.2 php7.2-gd重新启动appache2 sudo systemctl apache2
