我有一个专用的根服务器运行Debian和管理面板我使用directadmin。从今天下午开始，我遇到以下问题：我的网站不再可访问，因为服务httpd已停止且无法启动。当我尝试启动服务时，它始终跟随错误消息：httpd (no pid file) not running。
我发现它与我以前为多个域安装SSL证书这一事实有关。
我已经尝试安装工具strace以找出导致问题的SSL证书（域）。遗憾的是，无法使用以下命令启动strace工具：strace -f apache2ctl start
错误消息始终为：command not found
如果我尝试通过directadmin启动httpd服务，则出现以下错误消息：/etc/init.d/httpd start> / dev / null 2> & 1
我还查看了服务httpd的errorlogs error_log，发现了以下错误代码：

这是我的主要Apache HTTP服务器配置文件。
#
# This is the main Apache HTTP server configuration file. It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.4> for detailed information.
# In particular, see
# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path. If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used. If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "/etc/httpd"
#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.

我希望有人可以帮助解决这个奇怪的问题。我会很开心的。
答案 0 :(得分：4)
日志中的消息：
服务器证书不包含匹配的ID 服务器名称
表示问题。检查证书：
openssl x509 -in certificate.crt -text -noout
然后在您的apache配置文件中使用ServerName指令定义相同的服务器名称。
答案 1 :(得分：0)
就我而言，这是由于SSL证书所致。该证书为二进制格式，并将其转换为base64可解决该错误。
答案 2 :(得分：0)
就我而言，它是 SSL 证书共享。
我已从通配符证书切换到每个子域的 Letencrypt 证书，但由于证书共享而中断...
一旦我为每个子域修复了每个 SSL，它就开始正常工作。
问题是含糊不清的错误消息，没有详细说明它到底失败在哪里。
