记一次在 nginx 配置 HTTPS 的经历

之前使用apache，懒得去看文档了，重新弄个nginx来搞。nginx的server配置很是简单，因为conf里面自带了https server的配置模板。。。

免费CA选择的是https://letsencrypt.org/。

获取两个必要的东西: 证书 和 私钥 也十分简单，网站有操作就不细说了。

获取到这两样东西，在nginx的conf里面配置二者的路径即可。一般在/etc/letsencrypt的live中。

主要是网站访问时从HTTP转HTTPS的技巧：nginx监听80端口肯定有个默认主页，只要在默认主页里面重定向即可：

index.html

这里有个疑问，假设直接访问某个页面，这样的机制就不会有效果了，如何做呢？

rewrite是个选择:

即在conf中http的server配置中添加

rewrite ^(.*)$  https://$host$1 permanent;

将所有80端口的请求都rewrite到https上面。

还遇到一个问题：

nginx的server root目录下面的子目录无法访问的问题。

权限配置正确，死活找不到原因，后来看到一个nginx的配置：

在conf中写：

autoindex on;

即可。。。

现在全站即开启HTTPS了。

另外就是当前的nginx配置，作为以后参考：
