SSL会话的简化过程
(1) 客户端发送可供选择的加密方式，并向服务器请求证书；
(2) 服务器端发送证书以及选定的加密方式给客户端；
(3) 客户端取得证书并进行证书验正：
如果信任给其发证书的CA：
(a) 验正证书来源的合法性；用CA的公钥解密证书上数字签名；
(b) 验正证书的内容的合法性：完整性验正
(c) 检查证书的有效期限；
(d) 检查证书是否被吊销；
(e) 证书中拥有者的名字，与访问的目标主机要一致；
(4) 客户端生成临时会话密钥（对称密钥），并使用服务器端的公钥加密此数据发送给服务器，完成密钥交换；
(5) 服务用此密钥加密用户请求的资源，响应给客户端；
注意：SSL会话是基于IP地址创建；所以单IP的主机上，仅可以使用一个https虚拟主机；
回顾几个术语：PKI，CA，CRL，X.509 (v1, v2, v3)
配置httpd支持https：
(1) 为服务器申请数字证书；
测试：通过私建CA发证书
(a) 创建私有CA
(b) 在服务器创建证书签署请求
(c) CA签证
(2) 配置httpd支持使用ssl，及使用的证书；
# yum -y install mod_ssl
配置文件：/etc/httpd/conf.d/ssl.conf
DocumentRoot
ServerName
SSLCertificateFile
SSLCertificateKeyFile
(3) 测试基于https访问相应的主机；
# openssl s_client [-connect host:port] [-cert filename] [-CApath directory] [-CAfile filename]
测试实例过程：

接下来把httpd.csr 传给ca服务器
[root@server ssl]# scp httpd.csr root@192.168.244.101:/tmp/
在ca服务器签署证书
[root@bogon CA]# openssl ca -in /tmp/httpd.csr -out certs/www.web1.com.crt -days 365
Using configuration from /etc/pki/tls/openssl.cnf
Check that the request matches the signature

再将签署好的证书返回给httpd服务器
[root@bogon CA]# scp certs/www.web1.com.crt 192.168.244.100:/etc/httpd/ssl
接下来配置httpd，让其支持使用ssl
[root@server ssl]# yum install -y mod_ssl
[root@server ssl]# httpd -M |grep ssl
ssl_module (shared)
[root@server ssl]# rpm -ql mod_ssl

浏览器要先导入ca
通过浏览器测试：
18、httpd自带的工具程序
htpasswd: basic认证基于文件实现时，用到的账号密码文件生成工具；
apachectl：httpd自带的服务控制脚本，支持start, stop；
apxs：由httpd-devel包提供的，扩展httpd使用第三方模块的工具；
rotatelogs：日志滚动工具；
access.log -->
access.log, access.1.log
access.log, access.1.log, access.2.log
suexec：
访问某些有特殊权限配置的资源时，临时切换至指定用户运行；
ab: apache benchmark
19、http压力测试工具
ab
webbench
http_load
jmeter
loadrunner
tcpcopy
ab [OPTIONS] URL
-n: 总的请求数
-c：模拟的并发数 （类似于多少个人同时请求）
-k: 以持久连接模式测试
ulimit -n #: 调整当前用户所同时打开的文件数；
测试例子：
[root@bogon CA]# ab -c 100 -n 10000 http://192.168.244.100/deflate.html
