nginx 80端口重定向到443端口

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;    ....}

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;    }  }}
