假设apache已经装好
1、使用yum install openssl,安装openssl
2、开启httpd.conf中LoadModule ssl_module modules/mod_ssl.so
3、制作证书
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: (输入一个密码)
Verifying - Enter pass phrase for ca.key: (再输入一次密码)
......
Self-sign the root CA... (签署根证书)
Enter pass phrase for ca.key: (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]:GanSu//随你喜欢
Locality Name (eg, city) [Sitiawan]:LanZhou//随你喜欢
Organization Name (eg, company) [My Directory Sdn
Bhd]:lzu//随你喜欢
Organizational Unit Name (eg, section) [Certification Services
Division]:lzu//随你喜欢
Common Name (eg, MD Root CA) []:dslab//随你喜欢
Email Address []:sunyanmeng@gmail.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]:GanSu
Locality Name (eg, city) [Sitiawan]: LanZhou
Organization Name (eg, company) [My Directory Sdn Bhd]:lzu
Organizational Unit Name (eg, section) [Secure Web Server]:lzu
Common Name (eg, www.domain.com) []:localhost
Email Address []:sunyanmeng@gmail.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: (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
下面要按照ssl.conf里面的设置，将证书放在适当的位置。
# chmod 400 server.key
# 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
4、配置ssl.conf(/etc/httpd/conf/ssl.conf)
打开ssl.conf文件
<VirtualHost *:443>
DocumentRoot "/var/www/html/"#你的WEB目录，和vhost里配置一样。
ServerName www.xxx.com:443
SSLCertificateFile /etc/httpd/conf.d/ssl.crt#你的文件在哪里就写哪里的路径
SSLCertificateKeyFile /etc/httpd/conf.d/ssl.key#你的文件在哪里就写哪里的路径
SSLCertificateChainFile /etc/httpd/conf.d/ca.crt#你的文件在哪里就写哪里的路径
</VirtualHost>
5、加载ssl的方式启动apache（这步很重要）
找到你的apachectl位置，
apachectl -D SSL -k start
