Apache SSL 配置不生效

我在我的伺服器上配置了一個通過 SSL 提供服務的站點，但它根本不可用。

$ nmap localhost
PORT     STATE SERVICE
22/tcp   open  ssh
25/tcp   open  smtp
80/tcp   open  http

我的防火牆允許埠 443 進入並且 apache2 服務正在執行。

似乎存在一個普遍的問題，即雖然包含在 中apache2.conf，但該文件/etc/apache2/sites-enabled/default-ssl.conf並未被考慮在內。

$ apache2ctl -S
VirtualHost configuration:
1.23.45.67:80         is a NameVirtualHost
        default server 12345.yourvserver.net (/etc/apache2/sites-enabled/000-default.conf:1)
        port 80 namevhost 12345.yourvserver.net (/etc/apache2/sites-enabled/000-default.conf:1)
        port 80 namevhost my.doma.in (/etc/apache2/sites-enabled/000-default.conf:31)
ServerRoot: "/etc/apache2"
Main DocumentRoot: "/var/www"
Main ErrorLog: "/var/log/apache2/error.log"
Mutex rewrite-map: using_defaults
Mutex default: dir="/var/lock/apache2" mechanism=fcntl 
Mutex mpm-accept: using_defaults
Mutex watchdog-callback: using_defaults
PidFile: "/var/run/apache2/apache2.pid"
Define: DUMP_VHOSTS
Define: DUMP_RUN_CFG
User: name="www-data" id=99
Group: name="www-data" id=99

ports.conf 聲明如下：

Listen 80

<IfModule ssl_module>
       Listen 443
</IfModule>

<IfModule mod_ssl.c>
       Listen 443
</IfModule>

<IfModule mod_gnutls.c>
       Listen 443
</IfModule>

排除註釋行，apache2.conf 如下所示：

ServerName localhost
Mutex file:${APACHE_LOCK_DIR} default
PidFile ${APACHE_PID_FILE}
Timeout 300
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 5
User ${APACHE_RUN_USER}
Group ${APACHE_RUN_GROUP}
HostnameLookups Off
ErrorLog ${APACHE_LOG_DIR}/error.log
LogLevel warn

       Options Indexes FollowSymLinks

</Directory>

AccessFileName .htaccess

       Require all denied
</FilesMatch>

LogFormat "%{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent

IncludeOptional conf-enabled/*.conf

IncludeOptional sites-enabled/*.conf

也有一個錯誤，但我無法按照這個執行緒中最流行的答案解決它（而且我不明白為什麼 envvars 應該與公共文件所在的目錄有任何關係。）

$ apache2 -V

好吧，這有點尷尬。我忘了跑a2enmod ssl。
