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-2.2.22.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-2.2.22.tar.gz
cd httpd-2.2.22
./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

     
     
1 [root@BlackGhost ssl]# ./CA.sh -newca //建立主证书
2 CA certificate filename ( or enter to create)
3
4 Making CA certificate ...
5 Generating a 1024 bit RSA private key
6 ............++++++
7 ......++++++
8 writing new private key to ' ./demoCA/private/./cakey.pem '
9   Enter PEM pass phrase:
10 Verifying - Enter PEM pass phrase:
11 Verify failure
12   Enter PEM pass phrase:
13 Verifying - Enter PEM pass phrase:
14 -----
15 You are about to be asked to enter information that will be incorporated
16   into your certificate request.
17 What you are about to enter is what is called a Distinguished Name or a DN.
18 There are quite a few fields but you can leave some blank
19 For some fields there will be a default value,
20 If you enter ' . ' , the field will be left blank.

29
30 Please enter the following ' extra ' attributes
31 to be sent with your certificate request
32 A challenge password []:******************
33 An optional company name []:
34 Using configuration from /etc/ssl/openssl.cnf
35   Enter pass phrase for ./demoCA/private/./cakey. pem: //填的是上面的PEM密码
