编辑Apache根目录下 conf/httpd.conf 文件，
找到 #LoadModule ssl_module modules/mod_ssl.so 和 #Include conf/extra/httpd-ssl.conf，去掉前面的#号注释；
编辑Apache根目录下 conf/extra/httpd-ssl.conf 文件，修改如下内容：
<VirtualHost www.domain.com:443> DocumentRoot "/var/www/html" ServerName www.domain.com SSLEngine on SSLCertificateFile /usr/local/apache/conf/2_www.domain.com_cert.crt SSLCertificateKeyFile /usr/local/apache/conf/3_www.domain.com.key SSLCertificateChainFile /usr/local/apache/conf/1_root_bundle.crt </VirtualHost>
