配置客户端身份验证后无法启动Apache Server

Question

CentOS 7 | Apache 2.4.6

---

我已经构建了一个私有证书颁发机构（CA）和两个证书（一个用于服务器，一个用于客户端）。

然后，我将Apache配置为使用证书X.509以回答HTTPS连接，一切都很顺利（我在浏览器中看到它）。

然后，当我配置客户端身份验证时，重新启动服务器并出现以下错误：

httpd.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 httpd.service”和“journalctl -xe”。

现在它出现“语法正常”但我仍然无法启动服务器，使用以下命令获得以下错误：

。 systemctl status httpd.service

我将离开我用于配置客户端身份验证的过程。我会在问题的底部留下一些有用的文件。

配置客户端身份验证的过程

1. 首先在文件“/etc/httpd/conf.d/ssl.conf”中找到选项“SSLCACertificateFile”：vi +/SSLCACertificateFile /etc/httpd/conf.d/ssl.conf
2. 更新了以下路径：/etc/pki/CA/certs/ca.crt

这是CA证书的位置。

注意：客户端的证书位于文件夹/ etc / pki / CA / certs中。配置客户端身份验证时，我不确定这是否会导致任何问题。 （更新：编辑1）

3. 删除了指令“SSLVerifyClient require”上的“＃”。
4. 使用:wq保存更改并退出文件，然后重新启动服务器：systemctl restart httpd

用于调试的有用文件

。 “etc / hosts”（添加IP +主机）

。 “/ etc / hostname”（可以用hostnamectl set-hostname new-hostname完成）

。 “等/的httpd / conf目录/ httpd.conf文件”

. "/etc/HTTP的/conf.的/收视率.conf"

。 “在/ var /日志/的httpd / error_log中”

Answer 1

我使用了另一个上下文构建的证书，重新启动Apache，错误没有显示。

这意味着错误必须与证书一起。

鉴于此，我仔细观察了我用于构建CA的过程（我将在此答案的底部添加过程）并找到错误。

我使用的是“临时”证书而不是cacert.pem。

创建CA的过程：

1. openssl genrsa -des3 -out /etc/pki/CA/private/cakey.pem
2. openssl req -new -key /etc/pki/CA/private/cakey.pem -out /etc/pki/CA/ca.crt
3. openssl x509 -req -days 100 -in ca.crt -out cacert.pem -signkey private/cakey.pem
