SSLEngine 开启时 Apache 无法启动

我的 SSL 虚拟主机就是这么简单：

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>

当我尝试使用以下命令重新启动 Apache 时apache2ctl configtest && systemctl restart apache2：

语法 OK
apache2.service 的作业失败，因为控制进程退出并显示错误代码。有关详细信息，请参阅“systemctl status apache2.service”和“journalctl -xe”。

但是当我关闭 SSLEngine 时，SSLEngine offapache 可以正常启动并且正常。

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

httpd (no pid file) not running为什么我打开时会出现该错误SSLEngine？
没有任何东西阻塞端口 443，因为当我运行lsof -i :443结果为空时。

我在 Linux/SUSE 上使用 Apache/2.4.23

答案1

这表明证书存在问题，httpd 无法加载证书，因此无法正常启动。通常，除非您对 SSL 的错误日志记录级别较高，否则不会显示这些错误。只需设置LogLevel ssl:trace8进行测试，然后在工作时将其删除。

确保证书是 PEM 格式（ASCII），它们彼此匹配并且存在于您指向它们的路径中：

openssl x509 -in /etc/ssl/certs/apache-selfsigned.crt -noout -modulus
openssl rsa -in /etc/ssl/private/apache-selfsigned.key -noout -modulus

两个命令的输出应该返回相同的结果，如果不是，则它们不正确。

答案2

我想感谢所有其他回复的人，但问题出在文件中ssl-globals.conf。

这两个指令导致 Apache 崩溃

SSLUseStapling on
SSLStaplingCache "shmcb:logs/stapling-cache(150000)"

我刚刚评论了它们，现在它起作用了。我不知道为什么，但科学是基于证据的。
