最近在研究Linux下的apache-ssl配置，写点个人小心得，新人发博，敬请见谅。
软件环境
Apache Httpd 2.2.29 (http://httpd.apache.org )
OpenSSL 1.0.1h (http://www.openssl.org/source )
SSL-Tools (http://www.openssl.org/contrib/ssl.ca-0.1.tar.gz )
1. OpenSSL
#tar zxvf openssl-1.0.1h.tar.gz
#cd openssl-1.0.1h
#./config
#make
#make install
此举将安装最新的OpenSSL到/usr/local/ssl目录中，无需理会系统中已有版本的OpenSSL，也不要去卸载它，否则会导致很多的应用程序无法正常执行，例如X窗口无法进入等错误。
2. Apache Httpd
#tar zxvf httpd-2.2.29.tar.gz
#cd httpd-2.2.29
#./configure --prefix=/usr/local/apache/httpd --enable-ssl=static --with-ssl=/usr/local/ssl
#make
#make install
此步骤在/apache/httpd目录中安装httpd服务(通过参数--prefix指定)，同时使用--with-ssl指定刚才所安装OpenSSL的路径，用于将mod_ssl静态的编译到httpd服务中。
3.制作证书
我们必须手工来生成SSL用到的证书，对证书不熟悉的人，有一个工具可以使用：http://www.openssl.org/contrib/ssl.ca-0.1.tar.gz 。下面是如何通过这个工具来生成证书的过程：
#cp ssl.ca-0.1.tar.gz /usr/local/apache/httpd/conf
#cd /usr/local/apache/conf
#tar zxvf ssl.ca-0.1.tar.gz
#cd ssl.ca-0.1
#./new-root-ca.sh (生成根证书)
No Root CA key round. Generating one
Generating RSA private key, 1024 bit long modulus
...........................++++++
....++++++
e is 65537 (0x10001)
Enter pass phrase for ca.key:12345 (输入一个密码)
Verifying - Enter pass phrase for ca.key: 12345(再输入一次密码)
......
Self-sign the root CA... (签署根证书)
Enter pass phrase for ca.key:12345 (输入刚刚设置的密码)
........
........ (下面开始签署)
Country Name (2 letter code) [MY]:CN
State or Province Name (full name) [Perak]:SD //随你喜欢
Locality Name (eg, city) [Sitiawan]:QD //随你喜欢
Organization Name (eg, company) [My Directory Sdn Bhd]:GX //随你喜欢
Organizational Unit Name (eg, section) [Certification Services Division]:GX //随你喜欢
Common Name (eg, MD Root CA) []:gaoxin.com //随你喜欢
Email Address []:12345@163.com//随你喜欢
这样就生成了ca.key和ca.crt两个文件，下面还要为我们的服务器生成一个证书：
# ./new-server-cert.sh server (这个证书的名字是server)
......
......
Country Name (2 letter code) [MY]:CN
State or Province Name (full name) [Perak]:SD
Locality Name (eg, city) [Sitiawan]: QD
Organization Name (eg, company) [My Directory Sdn Bhd]:GX
Organizational Unit Name (eg, section) [Secure Web Server]:GX
Common Name (eg, www.domain.com) []:gaoxiaoit.com (必须与上面的不同，否则报错)
Email Address []:123456@163.com
这样就生成了server.csr和server.key这两个文件。
还需要签署一下才能使用的：
# ./sign-server-cert.sh server
CA signing: server.csr -> server.crt:
Using configuration from ca.config
Enter pass phrase for ./ca.key:12345 (输入上面设置的根证书密码)
Check that the request matches the signature
Signature ok
The Subject's Distinguished Name is as follows
countryName:PRINTABLE:'CN'
stateOrProvinceName:PRINTABLE:'GanSu'
localityName:PRINTABLE:'LanZhou'
organizationName:PRINTABLE:'lzu'
organizationalUnitName:PRINTABLE:'lzu'
commonName:PRINTABLE:'localhost'
emailAddress :IA5STRING:'sunyanmeng@gmail.com'
Certificate is to be certified until Jan 19 21:59:46 2011 GMT (365 days)
Sign the certificate? [y/n]:y
1 out of 1 certificate requests certified, commit? [y/n]y
Write out database with 1 new entries
Data Base Updated
CA verifying: server.crt <-> CA cert
server.crt: OK
配置conf/extr/httpd-ssl.conf
找到#include conf/extra/httpd-ssl.confm去掉注释
下面要按照httpd-ssl.conf里面的设置，将证书放在适当的位置。
# cd ..
# mkdir ssl.key
# mv ssl.ca-0.1/server.key ssl.key
# mkdir ssl.crt
# mv ssl.ca-0.1/server.crt ssl.crt
然后就可以启动啦！
# cd /usr/local/apache
注意，apache2.2之后不支持startssl，所以只用start即可
# ./bin/apachectl start
4. 测试HTTP服务
使用浏览器打开地址：https://127.0.0.1 完毕！
