如何在Apache中创建和安装自签名证书-木庄网络博客

SSL对于用户和Web服务器之间的安全通信很有用。证书在公共线路上传输时对数据进行加密，这样它就不会受到黑客的攻击。自签名证书是免费使用的，但不在生产环境中使用，例如使用信用卡、Paypal信息的机密数据。本篇文章将介绍关于在Linux系统上的Apache服务器中创建和安装自签名证书。

步骤1：安装mod_ssl包

要设置SSL证书，请确保在系统上安装了mod_ssl。如果尚未安装，需要使用以下命令进行安装。另外，安装openssl包来创建证书。

$ sudo apt-get install openssl          # Debian based systems 
$ sudo yum install mod_ssl openssl      # Redhat / CentOS systems 
$ sudo dnf install mod_ssl openssl      # Fedora 22+ systems

步骤2：创建自签名证书

安装mod_ssl和openssl后，使用以下命令为你的域创建一个自签名证书。

1 2	`$ sudo mkdir -p /etc/pki/tls/certs` `$ sudo cd /etc/pki/tls/certs`

现在创建SSL证书

1	`$ sudo openssl req -x509 -nodes -newkey rsa:2048 -keyout example.com.key` `-out` `example.com.crt`

输出
