配置客户端身份验证后无法启动 Apache 服务器

配置客户端身份验证后无法启动 Apache 服务器

CentOS 7 |Apache 2.4.6


我已经建立了一个私人证书颁发机构(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 来应答 HTTPS 连接,一切顺利(我在浏览器中看到了它)。

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,因为控制进程以错误代码退出。有关详细信息,请参阅“systemctl status httpd.service”和“journalctl -xe”。

现在显示“语法正常”,但我仍然无法启动服务器,使用以下命令出现以下错误:

.systemctl 状态 httpd.service

我将在下面介绍我用来配置客户端身份验证的过程。我将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. 将路径更新为:/etc/pki/CA/certs/ca.crt

这是 CA 证书的位置。

需要注意的是:客户端的证书位于文件夹 /etc/pki/CA/certs 内。我不确定这是否会在配置客户端身份验证时导致任何问题。(更新:编辑1

  1. 删除了指令“SSLVerifyClient require”上的“#”。

  2. 保存更改并退出文件,:wq然后重新启动服务器:systemctl restart httpd


调试有用的文件

. “etc/hosts” (添加 IP + 主机)

等/主机

. “/etc/hostname” (可以使用 来完成hostnamectl set-hostname new-hostname

/etc/主机名

“etc/httpd/conf/httpd.conf”

等/httpd/conf/httpd.conf

。 “/etc/httpd/conf.d/ssl.conf”

/etc/httpd/conf.d/ssl.conf

.“/var/log/httpd/错误日志”

答案1

我已经使用了在另一个上下文中构建的证书,重新启动了 Apache,错误没有显示。

这意味着错误一定出在证书上。

鉴于此,我仔细重新观察了我用于构建 CA 的程序(我会在该答案的底部添加该程序)并发现了错误。

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
