openssl建立证书，非常详细配置ssl+apache
一，什么是ssl

SSL证书通过在客户端浏览器和Web服务器之间建立一条SSL安全通道（Secure socket layer(SSL)安全协议是由Netscape Communication公司设计开发。该安全协议主要用来提供对用户和服务器的认证；对传送的数据进行加密和隐藏；确保数据在传送中不被改变，即数据的完整性，现已成为该领域中全球化的标准。由于SSL技术已建立到所有主要的浏览器和WEB服务器程序中，因此，仅需安装服务器证书就可以激活该功能了）。即通过它可以激活SSL协议，实现数据信息在客户端和服务器之间的加密传输，可以防止数据信息的泄露。保证了双方传递信息的安全性，而且用户可以通过服务器证书验证他所访问的网站是否是真实可靠。

安全套接字层 (SSL) 技术通过加密信息和提供鉴权，保护您的网站安全。一份 SSL 证书包括一个公共密钥和一个私用密钥。公共密钥用于加密信息，私用密钥用于解译加密的信息。浏览器指向一个安全域时，SSL 同步确认服务器和客户端，并创建一种加密方式和一个唯一的会话密钥。它们可以启动一个保证消息的隐私性和完整性的安全会话。

首先要有一个主证书，然后用主证书来签发服务器证书和客户证书，服务器证书和客户证书是平级关系，SSL所使用的证书可以自己生成，也可以通过一个商业性CA（如Verisign 或 Thawte）签署证书。签发证书的问题：如果使用的是商业证书，具体的签署方法请查看相关销售商的说明；如果是知己签发的证书，可以使用openssl 自带的CA.sh脚本工具。如果不为单独的客户端签发证书，客户端证书可以不用生成，客户端与服务器端使用相同的证书。

二，安装所要的软件

openssl ：wget http://www.openssl.org/source/openssl-1.0.0a.tar.gz

apache： wget http://www.apache.org/dist/httpd/httpd-2.2.16.tar.gz

三，安装

在正式安装前，请不要直接看下面的安装，请看最后一部分，那是我安装时候所遇到的问题，这样可以使你少走不少弯路，我安装的时候，就走了不少弯路。

1，安装openssl

tar zxvf openssl-1.0.0a.tar.gz
cd openssl-1.0.0a
./config --prefix=/usr/local/openssl
make && make install

2,安装apache

如果你已经安装了apache，你又不想重新编译的话，请参考mod_ssl模块的安装，也就是添加ssl模块而已。

tar zxvf httpd-2.2.16.tar.gz
cd httpd-2.2.16
./configure --prefix=/usr/local/apache --enable-ssl --enable-rewrite --enable-so --with-ssl=/usr/local/openssl
make && make install

如果你是yum install ,apt-get,pacman这样的软件管理工具进行安装的话，上面的二步可以省掉。

3，创建主证书

在/usr/local/apache/conf/下面建个目录ssl

3.1，mkdir ssl

3.2，cp /openssl的安装目录/ssl/misc/CA.sh /usr/local/apache/conf/ssl/

3.3 用CA.sh来创建证书

5,产生客户端证书

生成客户私钥：
openssl genrsa -des3 -out client.key 1024

生成客户证书
openssl req -new -key client.key -out client.csr

签证：
openssl ca -in client.csr -out client.crt

转换成pkcs12格式，为客户端安装所用
openssl pkcs12 -export -clcerts -in client.crt -inkey client.key -out client.pfx

这一步根安装服务器的证书差不多，不同的是签证，最后安装的时候，client.pfx的密码要记住，在客户端安装的时候要用到的。

[root@BlackGhost ssl]# openssl pkcs12 -export -clcerts -in client.crt -inkey client.key -out client.pfx
Enter pass phrase for client.key:
Enter Export Password:
Verifying - Enter Export Password:

客户端和服务器端都可以使用服务器端证书，所以这一步不做也行。

6，集中所以证书和私私钥到一起

#cp demoCA/cacert.pem cacert.pem

同时复制一份证书，更名为ca.crt
#cp cacert.pem ca.crt

7，apache配置

vi /usr/local/apache/conf/extra/ssl.conf
查看复制打印 ?
1. ssl开启
2. SSLEngine on
4. 指定服务器证书位置
5. SSLCertificateFile /usr/local/apache/conf/ssl/server.crt
7. 指定服务器证书key位置
8. SSLCertificateKeyFile /usr/local/apache/conf/ssl/server.key
10. 证书目录
11. SSLCACertificatePath /usr/local/apache/conf/ssl
13. 根证书位置
14. SSLCACertificateFile /usr/local/apache/conf/ssl/cacert.pem
16. 要求客户拥有证书
17. SSLVerifyClient require
18. SSLVerifyDepth 1
19. SSLOptions +StdEnvVars
21. 记录log
22. CustomLog "/usr/local/apache/logs/ssl_request_log"
23. "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x "%r" %b"
vi /usr/local/apache/conf/extra/httpd_vhosts.conf
查看复制打印 ?
1. listen 443 https
2. NameVirtualHost *:443
3. <VirtualHost _default_:443>
5. DocumentRoot "/home/zhangy/www/metbee/trunk/src/web"
6. ServerName *:443
7. ErrorLog "/home/zhangy/apache/www.metbee.com-error.log"
8. CustomLog "/home/zhangy/apache/www.metbee.com-access.log" common
9. Include conf/extra/ssl.conf
11. </VirtualHost>
vi /usr/local/apache/conf/httpd.conf把Include conf/extra/httpd-vhosts.conf前面的注释去掉

启动 /usr/local/apache/bin/apachectl -D SSL -k start

Server *:10000 (RSA)
Enter pass phrase:输入的是server的密钥

OK: Pass Phrase Dialog successful.

8,安装客户端证书

把ca.crt和client.pfx copy到客户端，双击client.pfx就会进入证书的安装向导，下一步就行了，中间会让你输入密码

四，安装所遇到的问题

1，生成的密码很多，一会让输入密码，会忘得，并且主证书的密码和下面的证书的密码不能重得，会报错的，所以要搞个文本记下来。

2，升级openssl引发的问题

httpd: Syntax error on line 56 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/modules/libphp5.so into server: libssl.so.0.9.8: cannot open shared object file: No such file or directory

httpd: Syntax error on line 56 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/modules/libphp5.so into server: libcrypto.so.0.9.8: cannot open shared object file: No such file or directory

用ln -s来建立软链接，就可以了。不过这种方法不是万能的，比如我把libpng从1.2升到1.4，libjpeg从7.0升到8.0结果是系统差点崩掉，用软链接不管用，我把他们弄掉，从网上下的低版本重装。

3，证书的国家名称，省名要相同不然生成空证书，

The countryName field needed to be the same in the
CA certificate (cn) and the request (sh)

4，提示CommonName时，要添写全域名，会提示警告

RSA server certificate CommonName (CN) `cn' does NOT match server name!?

5，相同的证书不能生成二次，名字不一样也不行，也就是说server.cst和client.csr信息不能完相同，不然会报

failed to update database
TXT_DB error number 2

6，页面浏览时，会看到提示，你的证书是不可信的，是因为我配置的不对，还是自己建的证书就是不要信的呢？

7，当我加了SSLVerifyClient require SSLVerifyDepth 1 这二个配置时，在windows下面，要你输入证书后，就可以看到页面了，但在用firefox就是不行呢？看下面的ssl_request_log日志，192.168.18.3是用windows的IE浏览器

[09/Aug/2010:22:02:21 +0800] 127.0.0.1 TLSv1 DHE-RSA-CAMELLIA256-SHA "GET /robots.txt HTTP/1.1" 208
