实验须知：
实验主机1:192.168.1.11，作为web服务器
实验主机2:192.168.1.12，作为CA签署证书的主机
配置流程：
（1） 为服务器申请数字证书；这里出于测试的目的，需要建立私有CA
创建私有CA
在web服务器上创建证书签署请求
CA证书签署
（2） 配置httpd支持使用ssl及使用的证书
（3） 测试基于https访问的主机
配置步骤：
在12主机：
[root@node2 ~]# cd /etc/pki/CA [root@node2 CA]# (umask 077;openssl genrsa -out private/cakey.pem2048)Generating RSA private key, 2048 bit long modulus ..............................................................................+++ ..................................................................+++ e is 65537 (0x10001) [root@node2 CA]# openssl req -new -x509 -key private/cakey.pem -outcacert.pem -days 10000 CN BJ BJ Magedu Ops ca.mageu.com [root@node2 CA]# touch index.txt [root@node2 CA]# echo 01 > serial
在11主机：
#cd/etc/httpd/ #mkdir ssl #cd ssl # (umask077;openssl genrsa -out http.key 1024) #openssl req-new -key http.key -out http.csr CN BJ BJ MageEdu Ops www.a.com #scp http.csr@172.16.11.12:/tmp
在12主机：
[root@node2 tmp]# cd /tmp/ [root@node2 tmp]# opensslca -in http.csr -out http.crt -days 3655 [root@node2 tmp]#scp http.crt172.16.100.11:/etc/httpd/ssl/
在11主机：
#yum install mod_ssl-y #rpm -ql mod_ssl #vim /etc/httpd/conf.d/ssl.conf ……….. <VirtualHost192.168.1.11:443> DocumentRoot "/vhosts/a.com/htdocs" ServerName www.a.com:443 ……… SSLCertificateFile/etc/httpd/ssl/http.crt SSLCertificateKeyFile/etc/httpd/ssl/http.key ……….. #httpd–t #servicehttpd restart #ss–tnl …..查看是否有443端口……..
在12主机：
#cd/etc/pki/CA #scpcacert.pem 172.16.1.11:/tmp
此时可以在浏览器中输入：https://192.168.1.11测试；
最后一步，将/tmp目录下的证书cacert.pem文件导入windows桌面，并更改名为cacert.crt,双击安装证书即可；现在我们需要在浏览器中输入：https://www.a.com能正常显示网页信息，就在windows里面改hosts文件：
……..添加…………..
192.168.1.11 www.a.com
再次输入https://ww.a.com，观察显示结果
压力测试工具ab的使用：
用法：
#ab [options] URL
-c：请求的最大并发数
-n:总的请求数
-k:以持久连接的模式测试
使用示例：
