nginx 80端口重定向到443端口，也就是http访问自动跳转到https

配置如下： 
一、按照如下格式修改nginx.conf 配置文件，80端口会自动转给443端口，这样就强制使用SSL证书加密了。访问http的时候会自动跳转到https上面。

server {listen 80;server_name www.域名.com;rewrite ^(.*)$ https://${server_name}$1 permanent; }server {listen 443;server_name www.域名.com;root /home/wwwroot;ssl on;ssl_certificate /etc/nginx/certs/server.crt;ssl_certificate_key /etc/nginx/certs/server.key;....
}1234567891011121314

备注： ${server_name}可以换成$host

二、重启nginx。

三、示例(以下是我们生产的配置)

server {listen 80;server_name www.test.com;rewrite ^(.*)$ https://${server_name}$1 permanent; }server {listen 443;server_name www.test.com;ssl on;ssl_certificate   /etc/pki/CA/certs/214321311540956.pem;ssl_certificate_key  /etc/pki/CA/certs/214321311540956.key;ssl_session_timeout 5m;ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;ssl_protocols TLSv1 TLSv1.1 TLSv1.2;ssl_prefer_server_ciphers on;   index index.php index.htm index.html;error_page 404 /404.html;error_page 500 502 503 504 /50x.html;location ~ \.php {root /alidata/www/html;fastcgi_pass unix:/tmp/php-cgi.sock;fastcgi_index index.php;include   fastcgi.conf;    set $path_info "";    set $fastcgi_script_name_new $fastcgi_script_name;        if ($fastcgi_script_name ~*   "^(.+\.php)(/.+)$"  ) {            set $fastcgi_script_name_new $1;        set $path_info $2;}fastcgi_param   SCRIPT_FILENAME   $document_root$fastcgi_script_name_new;fastcgi_param   SCRIPT_NAME   $fastcgi_script_name_new;                    fastcgi_param   PATH_INFO $path_info;}location / {root /alidata/www/html;index index.php index.html index.htm;    if (!-e  $request_filename){rewrite ^(.*)$ /index.php$1 last;}}
