Nginx 配置将域名 xxx.com 301 跳转至 www.xxx.com

更新日期: 2024-08-18 阅读次数: 524 字数: 250 分类: Nginx

例如,我想将域名 sunzhongwei.com 自动跳转到 www.sunzhongwei.com。

Nginx 配置

server {
    # 默认是 80 端口
    server_name sunzhongwei.com;
    return 301 $scheme://www.sunzhongwei.com$request_uri;
}

验证配置,并重新加载配置

nginx -t
nginx -s reload

使用 certbot 自动安装免费的 SSL 证书,并自动修改 Nginx 配置

certbot --nginx -d sunzhongwei.com

certbot 修改后的 Nginx 配置

server {
    server_name sunzhongwei.com;
    return 301 $scheme://www.sunzhongwei.com$request_uri;

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/sunzhongwei.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/sunzhongwei.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

server {
    if ($host = sunzhongwei.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    server_name sunzhongwei.com;
    listen 80;
    return 404; # managed by Certbot
}

测试

在浏览器中输入

http://sunzhongwei.com 和 https://sunzhongwei.com,会看到都自动跳转到了 https://www.sunzhongwei.com。

验证成功。

警告信息

但是,如果我自己直接配置 443 端口,会报警告

2024/08/18 05:54:03 [warn] 1573658#1573658: protocol options redefined for 0.0.0.0:443 in /etc/nginx/conf.d/www.sunzhongwei.com.conf:67
2024/08/18 05:54:03 [warn] 1573658#1573658: protocol options redefined for 0.0.0.0:443 in /etc/nginx/conf.d/www.sunzhongwei2.com.conf:31

没有搞明白是什么问题,还是按照上面的配置即可。
