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 443
NameVirtualHost *:443
<VirtualHost *:443>

# General setup for the virtual host
DocumentRoot "/usr/local/httpd/htdocs/ssl"
ServerName ssl.baishiz.com:443
ServerAdmin you@example.com
ErrorLog "/usr/local/httpd/logs/error_log"
TransferLog "/usr/local/httpd/logs/access_log"

SSLEngine on
SSLProtocol all -SSLv2
SSLCipherSuite HIGH:MEDIUM:!aNULL:!MD5

SSLCertificateFile "/usr/local/httpd/server.crt"
SSLCertificateKeyFile "/usr/local/httpd/server.key"

<FilesMatch ".(cgi|shtml|phtml|php)$">
SSLOptions +StdEnvVars
</FilesMatch>
<Directory "/usr/local/httpd/cgi-bin">
SSLOptions +StdEnvVars
</Directory>
BrowserMatch "MSIE [2-5]"
nokeepalive ssl-unclean-shutdown
downgrade-1.0 force-response-1.0
CustomLog "/usr/local/httpd/logs/ssl_request_log"
"%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x "%r" %b"

</VirtualHost>
