linux下配置Apache基于加密的认证访问1、首先要确认安装了 mod_ssl模块
我的机器是centos是系统，执行下面命令
yum install -y mod_ssl
2、用openssl工具生成密钥，证书请求文件，证书
在/usr/local/httpd目下，执行以下命令。
2.1生成密钥
openssl genrsa 1024 > server.key
说明：这是用128位rsa算法生成密钥，得到server.key文件
2.2生成证书请求文件
openssl req -new -out server.csr
说明：这是用步骤1的密钥生成证书请求文件server.csr, 这一步提很多问题，一一输入
2.3生成证书
命令：openssl req -x509 -days 365 -key server.key -in server.csr > server.crt
说明：这是用步骤1,2的的密钥和证书请求生成证书server.crt，-days参数指明证书有效期，单位为天
3、 配置apache
修改httpd.conf
LoadModule ssl_module /usr/lib64/httpd/modules/mod_ssl.so
Include conf/extra/httpd-ssl.conf
修改httpd-ssl.conf
添加虚拟主机：
Listen 443NameVirtualHost *:443<VirtualHost *:443>
# General setup for the virtual hostDocumentRoot "/usr/local/httpd/htdocs/ssl"ServerName ssl.baishiz.com:443ServerAdmin you@example.comErrorLog "/usr/local/httpd/logs/error_log"TransferLog "/usr/local/httpd/logs/access_log"
