Question

我的服务器是Ubuntu，我正在运行Apache2。我正在使用apache指向我在tomcat中加载的网络应用。以下是我的000-default.conf文件。

<VirtualHost *:*>
    ProxyPreserveHost On

    # Servers to proxy the connection, or;
    # List of application servers:
    # Usage:
    # ProxyPass / http://[IP Addr.]:[port]/
    # ProxyPassReverse / http://[IP Addr.]:[port]/
    # Example:
    ProxyPass / http://0.0.0.0:8080/
    ProxyPassReverse / http://0.0.0.0:8080/

    ServerName localhost
</VirtualHost>

<VirtualHost *:443>

    SSL Engine On

    # Set the path to SSL certificate
    # Usage: SSLCertificateFile /path/to/cert.pem
    SSLCertificateFile /etc/apache2/ssl/STAR_myglukose_com.crt

    # Servers to proxy the connection, or;
    # List of application servers:
    # Usage:
    # ProxyPass / http://[IP Addr.]:[port]/
    # ProxyPassReverse / http://[IP Addr.]:[port]/
    # Example:
    ProxyPass / http://0.0.0.0:8080/
    ProxyPassReverse / http://0.0.0.0:8080/

    # Or, balance the load:
    # ProxyPass / balancer://balancer_cluster_name

</VirtualHost>

我指向Tomcat很好，但问题在于SSL。在为443创建虚拟主机后，我无法重启apache。我收到了一个错误。它要求我参考journalct1 -xe。该文件如下。

我尝试了各种方法解决此问题，包括将SSL Engine写为SSLEngine，执行sudo a2enmod ssl等，但同样的错误也会出现。

我该如何解决这个问题？

错误消息清楚地指出了问题：

AH00526: Syntax error on line 19 of /etc/apache2/sites-enabled/000-default.conf:
Invalid command 'SSL', perhaps misspelled or defined by a module not included in the server configuration

要解决问题，请查看特定行：

SSL Engine On

并通过删除SSL和引擎之间的空间来修复它：

SSLEngine On

无法在Apache中安装SSL
