【中文标题】nginx 和 SSL：502 错误网关

【英文标题】：nginx and SSL: 502 bad gateway

【问题描述】：

我真的希望你们能帮助我。我迷失了设置 ssl 的不同指南。

当我尝试访问我的网站时，我只收到502 Bad Gateway。普通的旧 nginx 工作得很好，没有强制 ssl 的“简单”ssl 也工作得很好。

这是我的配置文件。

【参考方案1】：

在我的情况下，我需要完全删除 apache，因为我的配置是使用 nginx

sudo service apache2 stop
sudo apt-get purge apache2 apache2-utils apache2.2-bin apache2-common
sudo apt-get autoremove
sudo rm -rf /etc/apache2
