如果一站点既要80 http访问，又要443https访问。

要让https和http并存，不能在配置文件中使用ssl on，配置listen 443 ssl;

实例

server
{

listen 80;
listen 443 ssl;
server_name www.iamle.com;
index index.html index.htm index.php;
root /home/wwwroot/www.iamle.com/;
#ssl on; 这里要注释掉
ssl_certificate /usr/local/nginx/conf/ssl/www_iamle_com.crt;
ssl_certificate_key /usr/local/nginx/conf/ssl/www_iamle_com.key;

#以下配置省略

}

It is good practice to configure separate servers for HTTP and HTTPS protocols from the very start. Although their functionalities currently seem equal, this may change significantly in the future and using a consolidated server may become problematic. However, if HTTP and HTTPS servers are equal, and you prefer not to think about the future, you may configure a single server that handles both HTTP and HTTPS requests by deleting the directive “ssl on” and adding the “ssl” parameter for *:443 port:
