我的Ubuntu 18.04-php7.1 php5.6上安装了多个php版本
当我使用php7.1时，apache会成功重启
但是当我使用以下命令切换到php5.6时：
sudo a2dismod php7.1 ; sudo a2enmod php5.6 ; sudo service apache2 restart
Apache给了我这个错误：
Job for apache2.service failed because the control process exited with error code.
See "systemctl status apache2.service" and "journalctl -xe" for details.
systemctl status apache2.service结果：

非常感谢任何建议。谢谢
这不仅仅是禁用模块。你必须设置一些默认值才能使工作
请尝试这个
设置从7.x到5.x
sudo a2dismod php7.1
sudo a2enmod php5.6
sudo update-alternatives --set php /usr/bin/php5.6
sudo update-alternatives --config php
sudo update-alternatives --set phar /usr/bin/phar5.6
sudo systemctl restart apache2
从5.x设置为7.x
sudo a2enmod php7.1
sudo a2dismod php5.6
sudo update-alternatives --set php /usr/bin/php7.1
sudo systemctl restart apache2
