RHEL6.3实现基于加密的用户认证验证访问

一、业务需求

Apache需要实现加密的基于用户身份认证的验证访问，来保证特定站点页面的安全。这里是需求的实现过程，请看如下分解。

二、具体实现步骤：
1、建立主目录及网页
[root@test1 www]# mkdir virt1
[root@test1 www]# ls
cgi-bin error html icons manual virt1
[root@test1 www]# cd virt1
[root@test1 virt1]# echo "welcomt to apache website">index.html
[root@test1 virt1]# ls
index.html
[root@test1 virt1]# cat index.html
welcomt to apache website

2、使用apache自带的htpasswd工具生成密码文件来作为用户访问认证的来源
格式：htpasswd options FilePath user
-c ：第一次创建时使用该选项
-m ：将密码使用MD5加密存放
-D ：从密码文件中删除用户

[root@test1 conf]# htpasswd -cm .htpasswd aaa
New password:
Re-type new password:
Adding password for user aaa
[root@test1 conf]# cat .htpasswd
aaa:$apr1$hhFTA/vU$GwUfNDRNGFGIyHWftqc2M1
[root@test1 conf]# htpasswd -m .htpasswd bbb
New password:
Re-type new password:
Adding password for user bbb
[root@test1 conf]# cat .htpasswd
aaa:$apr1$hhFTA/vU$GwUfNDRNGFGIyHWftqc2M1
bbb:$apr1$QHr2Dpff$wMtQI74PcbNOMrY0mPgpa0
[root@test1 conf]#

如果是要删除用户
#htpasswd -D .htpasswd aaa

3、对指定的网页目录使用基本身份认证验证
比如对test1.demo.com网站的访问需要基于用户认证验证
配置apache的主配置文件：/etc/httpd/conf/httpd.conf
NameVirtualHost 192.168.1.123:80
<VirtualHost 192.168.1.123:80>
DocumentRoot /var/www/virt1
ServerName test1.demo.com
ErrorLog logs/test1.demo.com-error.log
<Directory /var/www/virt1>
authName "realm"
AuthType basic
AuthUserFile /etc/httpd/conf/.htpasswd
Require User aaa bbb
</Directory>
</VirtualHost>
[root@test1 virt1]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: [ OK ]

4、加密配置
[root@test1 conf]# (umask 077;openssl genrsa -des3 -out server.key)
Generating RSA private key, 512 bit long modulus
....++++++++++++
....++++++++++++
e is 65537 (0x10001)
Enter pass phrase for server.key:
Verifying - Enter pass phrase for server.key:

[root@test1 conf]# openssl req -new -key server.key -out server.csr
Enter pass phrase for server.key:
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [CN]:CN
State or Province Name (full name) []:
Locality Name (eg, city) [Beijing]:Beijing
Organization Name (eg, company) [Default Company Ltd]:Tianli
Organizational Unit Name (eg, section) []:
Common Name (eg, your name or your server's hostname) []:test1.demo.com
Email Address []:

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
[root@test1 conf]# openssl ca -in server.csr -out server.crt
Using configuration from /etc/pki/tls/openssl.cnf
Enter pass phrase for /etc/pki/CA/private/my-ca.key:
Check that the request matches the signature
Signature ok
Certificate Details:

stateOrProvinceName = Hebei
organizationName = Default Company Ltd
commonName = test1.demo.com
X509v3 extensions:

Certificate is to be certified until Jan 31 05:37:44 2014 GMT (365 days)
Sign the certificate? [y/n]:y

将httpd.conf中的这一段复制放到ssl.conf中并修改和添加SSL认证语句
NameVirtualHost 192.168.1.123:443
<VirtualHost 192.168.1.123:443>
DocumentRoot /var/www/virt1
SSLEngine on
SSLCertificateFile /etc/httpd/conf/server.crt
SSLCertificateKeyFile /etc/httpd/conf/server.key
ServerName test1.demo.com
ErrorLog logs/test1.demo.com-error.log
<Directory /var/www/virt1>
authName "realm"
AuthType basic
AuthUserFile /etc/httpd/conf/.htpasswd
Require User aaa bbb
</Directory>
</VirtualHost>
注：需要将原httpd.conf文件中的这一段进行注释或屏蔽。
[root@test1 conf]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: [Thu Jan 31 01:29:41 2013] [warn] NameVirtualHost 192.168.1.123:80 has no VirtualHosts
Apache/2.2.15 mod_ssl/2.2.15 (Pass Phrase Dialog)
Some of your private key files are encrypted for security reasons.
In order to read them you have to provide the pass phrases.

Server test1.demo.com:443 (RSA)
Enter pass phrase:

OK: Pass Phrase Dialog successful.
[ OK ]
[root@test1 conf]#
