我的 SSL 虚拟主机就这么简单：

LoadModule ssl_module modules/mod_ssl.so

Listen 443
<VirtualHost *:443>
        DocumentRoot "/srv/www/test"
        ServerName <my_website_domain>

        SSLEngine on
        SSLCertificateFile    /etc/ssl/certs/apache-selfsigned.crt
        SSLCertificateKeyFile /etc/ssl/private/apache-selfsigned.key
</VirtualHost>

当我尝试重新启动 apache 时，apache2ctl configtest && systemctl restart apache2我得到：

apache2.service 的语法 OK
作业失败，因为控制进程以错误代码退出。有关详细信息，请参阅“systemctl status apache2.service”和“journalctl -xe”。

但是当我用 apache 关闭 SSLEngine 时，它SSLEngine off​​可以正常启动并且正常。

当我systemctl status apache2从 开始后运行时SSLEngine on，我得到：

为什么我httpd (no pid file) not running开机时会出现这个错误SSLEngine？
没有任何东西阻塞端口 443，因为当我运行时lsof -i :443结果为空。

我正在为 Linux/SUSE 使用 Apache/2.4.23

apache-2.4

我想将任何方案中的所有这些子域转发到 https 中的相应主域。我不想有几个服务器指令。

server {
    server_name *.autocosts.info
                *.autocouts.info
                *.autocostos.info
                *.autocosti.info
                *.autocustos.info
                *.autocosturi.info
                *.autokoszty.info;

    listen 80;
    listen 404;
    listen 443 ssl;

    return 301 https://$host$request_uri;
}

这似乎不起作用。是否$host包含子域？我怎样才能得到主域（没有子域）？

我知道我可以使用主域server_name ~^(www\.)?(?<domain>.+)$;，但它不限于上述域列表。

我有一个 VPS，我正在尝试远程访问我的 mysql 数据库。

我授予任何 IP 地址的 root 权限

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
FLUSH PRIVILEGES;

我在my.cnf文件中评论了这一行

#bind-address = 127.0.0.1

我重启了mysql

sudo service mysql restart

但是下一步（所有教程都提到过）涉及iptables从端口 3306 转发请求；iptables我意识到我的VPS甚至没有sudo service iptables status输出iptables: unrecognized service

我可以安装 iptables，但我可以用 nginx 实现同样的效果吗？也就是这个fort forwarding允许远程访问我的mysql数据库？
