通过在linux生成的证书，来配置nginx支持 https，通过配置重定向当访问 http 时转向到 https;
修改部分的ssl_protocols、ssl_ciphers 内容用于支持如某些IE浏览器可能对普通配置的https不支持；
server {
listen 80;
server_name www.domain.com domain.com;
rewrite ^(.*) https://$host$1 permanent;
}
# HTTPS server

server {
#listen 80;

#listen [::]:443 ssl http2 default_server;

error_page 500 502 503 504 404 /error.html;
location = /error.html {

}
}支持 ie浏览器访问 https的配置：
