nginx配置http和https可同时访问方法， listen ssl与 ssl on区别

nginx配置http和https可同时访问方法

给nginx配置SSL证书之后，https可以正常访问，http访问显示400错误，nginx的配置如下：

server {
listen 80 default backlog=2048;
listen 443;
server_name lvtao.net;
root /var/www/html;
ssl on;
ssl_certificate /usr/local/Tengine/sslcrt/lvtao.net.crt;
ssl_certificate_key /usr/local/Tengine/sslcrt/lvtao.net.key;
}

http访问的时候，报错如下：

400 Bad Request
The plain HTTP requset was sent to HTTPS port. Sorry for the inconvenience.
Please report this message and include the following information to us.
Thank you very much!

 

原因是http的请求被发送到https的端口上去了，所以才会出现这样的问题。

把ssl on；这行去掉，ssl写在443端口后面。这样http和https的链接都可以用，完美解决，修改后的配置如下：

server {
listen 80 default backlog=2048;
listen 443 ssl;
server_name lvtao.net;
root /var/www/html;
ssl_certificate /usr/local/Tengine/sslcrt/lvtao.net.crt;
ssl_certificate_key /usr/local/Tengine/sslcrt/lvtao.net.Key;
}
