我有一台安装了 zend server CE 的 ubuntu 12.04 服务器。我现在想启用 https，但根据文档中的第一步“a2enmod ssl”和“apache service restart”之后，根据 netstat -tap | grep http(s)！apache 既不监听 443，也不监听 80！
这是我在错误日志中看到的内容，但我无法理解：

有人知道我做错了什么吗？也许我应该采取一些额外的步骤让 apache 监听 443，但它完全停止监听 80，我不明白。
答案1
我没有做错什么，但升级到 Ubuntu 服务器 12.04 后，Zend Server CE 中的 SSL 支持就中断了。与此同时，Zend 通过为 Ubuntu 12.04 提供单独的 Zend Server 5.6 存储库解决了该问题。将此行添加到 /etc/apt/sources.list
"deb http://repos.zend.com/zend-server/5.6.0_ubuntu1204/deb server non-free"
答案2
您可以像这样启用默认 ssl 站点；
ln -s /etc/apache2/sites-available/default-ssl /etc/apache2/sites-enabled/000-default-ssl
这里有一些注释；
http://www.tc.umn.edu/~brams006/selfsign_ubuntu.html
您能粘贴命令的输出吗netstat，类似于这样；
# netstat -ltp | grep http
tcp 0 0 *:https *:* LISTEN 2592/httpd
tcp 0 0 *:http *:* LISTEN 2592/httpd
您还可以将任何特定的启动错误记录到日志文件中，如下所示；
apachectl -E /var/log/httpd/startup-err.log -k start
如果这还不能告诉你问题所在，那么就把它调到最大，像这样；
apachectl -e debug -E /var/log/httpd/startup-err.log -k restart
还将apachectl -S显示 httpd 所看到的虚拟主机配置；
# apachectl -S
VirtualHost configuration:
wildcard NameVirtualHosts and _default_ servers:
_default_:443 workstation001.config (/etc/httpd/conf.d/ssl.conf:75)
*:80 is a NameVirtualHost
default server www-redirect (/etc/httpd/conf.d/mystupidsite.com.conf:1)
port 80 namevhost www-redirect (/etc/httpd/conf.d/mystupidsite.com.conf:1)
Syntax OK
答案3
禁用 Curl 模块后服务器将正常启动。
手动禁用（因为服务器关闭时 Zend Web 界面将无法工作）：
1）编辑/usr/local/zend/etc/ext.d/curl.ini
;2）在前面放一个冒号extension=curl.so，这样就可以了，直到修复发布
PS Zend 表示针对 Ubuntu 的修复程序很快就会发布。
答案4
查看 /var/log/syslog，你会发现一些类似的描述：
May 30 19:15:39 virtualdev kernel: [ 397.265473] apache2[2009]: segfault at 0 ip 00007fa17e522eb6 sp 00007fffb5468f98 error 4 in libc-2.15.so[7fa17e3e7000+1b3000]
这表明当启用 mod ssl 时，libc-2.15.so 似乎存在问题。不知道谁会修复这个问题。
