Nginx 自動跳轉(zhuǎn)到HTTPS
方法一：
rewrite ^(.*)$ https://$host$1 permanent;
方法二：
適用于 80端口和443 配置在同一個 server{}內(nèi)
if ($server_port = 80) {
rewrite ^(.*)$ https://$host$1 permanent;
}
其他情況， 站點綁定很多域名，只讓某個域名跳轉(zhuǎn):
set $redirect_https 1;
if ($server_port = 80) {
set $redirect_https "${redirect_https}2";
}
if ($http_host = 'www.22.cn') {
set $redirect_https "${redirect_https}3";
}
if ($http_host = '22.cn') {
set $redirect_https "${redirect_https}3";
}
if ($redirect_https = "123") {
rewrite ^(.*)$ https://$host$1 permanent;
}
配置示例：
server {
listen 80;
server_name www.22.cn;
rewrite ^ https://$http_host$request_uri? permanent;
}
server {
listen 443;
ssl on;
ssl_certificate /etc/ssl/cacert.pem;
ssl_certificate_key /etc/ssl/privkey.pem;
server_name www.22.cn;
server_tokens off;
location / {
fastcgi_param HTTPS on;
fastcgi_param HTTP_SCHEME https;
}
}
